    Perineal wound complications following abdominoperineal resection (APR) is a common occurrence. Risk factors such as operative technique, preoperative radiation therapy, and indication for surgery (i.e., rectal cancer, anal cancer, or inflammatory bowel disease [IBD]) are strong predictors of these complications. Patient risk factors include diabetes, obesity, and smoking. Intraoperative perineal wound management has evolved from open wound packing to primary closure with closed suctioned tra...

    Perineal wound complications following abdominoperineal resection (APR) is a common occurrence. Risk factors such as operative technique, preoperative radiation therapy, and indication for surgery (i.e., rectal cancer, anal cancer, or inflammatory bowel disease [IBD]) are strong predictors of these complications. Patient risk factors include diabetes, obesity, and smoking. Intraoperative perineal wound management has evolved from open wound packing to primary closure with closed suctioned transabdominal pelvic drains. Wide excision is used to gain local control in cancer patients, and coupled with the increased use of pelvic radiation therapy, we have experienced increased challenges with primary closure of the perineal wound. Tissue transfer techniques such as omental pedicle flaps, and vertical rectus abdominis and gracilis muscle or myocutaneous flaps are being used to reconstruct large perineal defects and decrease the incidence of perineal wound complications. Wound failure is frequently managed by wet to dry dressing changes, but can result in prolonged hospital stay, hospital readmission, home nursing wound care needs, and the expenditure of significant medical costs. Adjuvant therapies to conservative wound care have been suggested, but evidence is still lacking. The use of the vacuum-assisted closure device has shown promise in chronic soft tissue wounds; however, experience is lacking, and is likely due to the difficulty in application techniques.

    Mesh reconstruction has been proved to be an effective method in incisional hernia repairment. This study was designed to evaluate the effect of reconstructing the pelvic floor with the high-inlay expanded polytetrafluoroethylene (ePTFE) GORE-TEX Dual Mesh (WLGore And Associates, Flagstuff, USA) in abdominoperineal resection. Sixty patients who underwent abdominoperineal resection for rectal cancer were assigned to 2 groups. The pelvic peritoneum was closed by routine sutures in group 1 and reconstructed with ePTFE in group 2. Postoperative complications and related items were evaluated and the patients were followed up. Time of confining to bed, bowel function recovery, fasting, and detaining drainage were significantly different between two groups (P < 0.05). In group 1, three patients developed bowel obstruction (10%), while no bowel obstruction was observed in group 2. Reconstruction of the pelvic floor using ePTFE results in quicker postoperative recovery and could decrease the risk of postoperative intestinal obstruction.

    We compared the oncological outcomes of sphincter-saving resection (SSR) and abdominoperineal resection (APR) in 409 consecutive patients with very low rectal cancer (i.e., tumors within 3 cm from the anal verge); 335 (81.9%) patients underwent APR and 74 (18.1%) underwent SSR. The APR group comprised higher proportions of men (67.5% vs 55.4%, P = .049) and advanced-stage patients (P cancer stages. RFS was associated with ypT and ypN stages in patients who received PCRT, while pN stage, lymphovascular invasion (LVI), and circumferential resection margin (CRM) involvement were risk factors for RFS in those who did not receive PCRT. Notably, SSR was not found to be a risk factor for RFS in either subgroup. Patients who were stratified according to cancer stage and PCRT also showed no differences in RFS according to the mode of surgery. Our results demonstrate that, regardless of PCRT administration, SSR is an effective treatment for very low rectal cancer, while CRM is an important prognostic factor for patients who did not receive PCRT.

    Full Text Available The problem of wound closure after abdominoperineal resection to treat oncological diseases remains unsolved. Formation of a primary suture in the perineal wound can lead to multiple postoperative complications: seroma, abscess, wound disruption with subsequent perineal hernia. Chemoradiation therapy as a standard for locally advanced rectal or anal cancer doesn’t improve results of treatment of perineal wounds and increases duration of their healing. Currently, surgeons have several reconstructive and plastic techniques to improve both direct and long-term functional treatment results. In the article, the most common methods of allo- and autotransplantation are considered, benefits and deficiencies of various techniques are evaluated and analyzed.

    The purpose of this study was to evaluate the outcomes of patients who underwent colorectal resections and coloanal anastomosis for radiation-induced recto-vaginal fistulas (RVFs). The effect of the surgical treatment technique on bowel function, fecal continence, and quality of life of patients was also evaluated. Twenty-one female patients, who received adjuvant chemotherapy and external beam pelvic radiation for cervix carcinoma after radical hysterectomy + pelvic/paraaortic lymph node dissection, having RVF but without tumor recurrence, were included. All patients underwent an ultralow anterior resection (n = 11) or an abdominoperineal pull-through resection and straight coloanal anastomosis (n = 10). A bowel functions questionnaire and a Fecal Incontinence Quality of Life (FIQLI) questionnaire were applied to patients pre-operatively and also 6 months after the ileostomy closure procedures. No recurrent RVF was observed in a mean follow-up period of 20 months after ostomy reversal procedures. The FIQLI depression, lifestyle, and embarrassment scores were significantly improved on the follow-up questionnaire. The mean pre- and post-operative incontinence scores were not significantly different. The spontaneous closure rate after a simple diverting stoma is quite low and local repair procedures usually result in failure. In selected patients, performing a nearly total rectum resection and maintaining the intestinal continuity with a coloanal anastomosis may be accepted as a safe and curative option. Recurrence-free outcome and the improvement of the quality of life of the patients represent the efficiency of this treatment modality.

    Our aim was to evaluate complications and long-term functional outcome in patients who had sphincter reconstruction using the gluteus maximus muscle as the neosphincter after abdominoperineal resection for rectal cancer treatment. Seven patients underwent reconstruction from 2000 to 2010. First, the sigmoid colon was brought down to the perineum as a perineal colostomy, with the procedure protected by a loop ileostomy. Reconstruction of the sphincter mechanism using the gluteus maximus took place 3 months later, and after another 8-12 weeks, the loop ileostomy was closed. We studied the functional outcome of these interventions with follow-up interviews of patients and objectively assessed anorectal function using manometry and the Cleveland Clinic Florida (Jorge-Wexner) fecal incontinence score. The mean follow-up was 56 months (median 47; range 10-123 months). One patient had a perianal wound infection and another had fibrotic stricture in the colocutaneous anastomosis that required several digital dilatations. Anorectal manometry at 3-month follow-up showed resting pressures from 10 to 18 mm Hg and voluntary contraction pressures from 68 to 187 mm Hg. Four patients had excellent sphincter function (Jorge-Wexner scores ≤5). Our preliminary results show that sphincter reconstruction by means of gluteus maximus transposition can be effective in restoring gastrointestinal continuity and recovering fecal continence in patients who have undergone APR with permanent colostomy for rectal cancer. Furthermore, the reconstruction procedure can be performed 2-4 years after the APR.

    Full Text Available Background: Laparoscopic colorectal surgery results in less post-operative pain, faster recovery, shorter length of stay and reduced morbidity compared with open procedures. Less or minimally invasive techniques have been developed to further minimise surgical trauma and to decrease the size and number of incisions. This study describes the safety and feasibility of using an umbilical multi-instrument access (MIA port (Olympus TriPort+ device with the placement of just one 12-mm suprapubic trocar in laparoscopic (double-port abdominoperineal resections (APRs in rectal cancer patients. Patients and Methods: The study included 20 patients undergoing double-port APRs for rectal cancer between June 2011 and August 2013. Preoperative data were gathered in a prospective database, and post-operative data were collected retrospectively. Results: The 20 patients (30% female had a median age of 67 years (range 46-80 years, and their median body mass index (BMI was 26 kg/m2 (range 20-31 kg/m2. An additional third trocar was placed in 2 patients. No laparoscopic procedures were converted to an open procedure. Median operating time was 195 min (range 115-306 min. A radical resection (R0 resection was achieved in all patients, with a median of 14 lymph nodes harvested. Median length of stay was 8 days (range 5-43 days. Conclusion: Laparoscopic APR using a MIA trocar is a feasible and safe procedure. A MIA port might be of benefit as an extra option in the toolbox of the laparoscopic surgeon to further minimise surgical trauma.

    In colorectal cancer surgery, surgical site infection (SSI) is a common complication, and especially, perineal wound complications after abdominoperineal resection (APR) remain to be serious clinical problems. Vacuum-assisted closure (VAC) therapy was first reported in another surgical field in 1997, and it is useful for treating complex wounds because it promotes granulation. VAC therapy has been recently used for open abdominal wounds. We introduced VAC for treating open perineal wound of APR and report the usefulness of it. We treated four patients. Firstly, in cases 1 and 2, we introduced VAC therapy to the management of SSI of the perineal wound after APR, and it was useful to control postoperative perineal wound infection. And also, in cases 3 and 4, we introduced VAC therapy to prevent perineal wound infection. Perineal wound infection did not happen. A vertical rectus abdominis myocutaneous flap has been reported to decrease perineal wound complications including pelvic abscess and open perineal wound; however it results in significant operative blood loss, increased operative time, and additional surgical complications. In our cases, there were no complications relating to VAC therapy and it promoted rapid wound healing. Our results suggested that it is an effective treatment for APR in a high-risk case of an open perineal wound. VAC therapy is a less invasive method and a useful treatment for open perineal wound of APR. Copyright © 2015 The Authors. Published by Elsevier Ltd.. All rights reserved.

    Perineal wound complications are a main problem after abdominoperineal resection (APR). There is little evidence concerning perineal wound management. This study describes and evaluates the role of vacuum-assisted closure (VAC) therapy in wound management strategies of perineal wound infections after APR. Patients undergoing APR for malignant disease between January 2007 and January 2013 were identified retrospectively. Data regarding occurrence and management of perineal wound complications were collected. Perineal wound infections were classified into minor or major complications and time to wound healing was measured. Time to wound healing was compared between patients receiving routine care or with additional VAC therapy. Of 171 included patients, 76 (44.4%) had minor and 36 (21.1%) major perineal wound infections. Management of major infected perineal wounds consisted of drainage (n = 16), debridement (n = 4), drainage combined with debridement (n = 4), VAC therapy alone (n = 5), or VAC therapy combined with other treatments (n = 7). Median duration of perineal wound healing in major infected wounds was 141 days (range 17-739). Median time to wound healing was not different in patients treated with (172 days, range 23-368) or without VAC therapy (131 days, range 17-739). In this study, VAC therapy did not shorten time to wound healing. However, prospective studies are required to investigate the role of VAC therapy in management of infected perineal wounds after APR. Up to then, wound management will remain to be based on clinical perception and 'gut-feeling'. Copyright © 2015 IJS Publishing Group Limited. Published by Elsevier Ltd. All rights reserved.

    Abdominoperineal resection (APR) following radiotherapy is associated with a high rate of perineal wound complications. The anterolateral thigh (ALT) flap, combined with the vastus lateralis (VL) muscle, can cover complex perineal and pelvic anteroposterior defects. This is used for the first time transabdominally through the pelvis and the perineum (TAPP) in the infero-posterior directions; this technique has been described and illustrated in this study. Among over 90 patients who underwent perineal reconstruction between May 2004 and June 2011, six patients presented high-grade tumours invading perineum, pelvis and sacrum, thereby resulting in a continuous anteroposterior defect. ALT + VL TAPP reconstructions were performed after extended APR and, subsequently, sacrectomy. Patients were examined retrospectively to determine demographics, operative time, complications (general and flap-related), time to complete healing and length of hospital stay. Long-term flap coverage, flap volume stability and functional and aesthetic outcomes were assessed. Mean operating time of the reconstruction was 290 min. No deaths occurred. One patient presented partial flap necrosis. Another patient presented a novel wound dehiscence after flap healing, due to secondary skin dissemination of the primary tumour. Following volumetric flap analysis on serial post-operative CT scans, no significant flap atrophy was observed. All flaps fully covered the defects. No late complications such as fistulas or perineal hernias occurred. Donor-site recovery was uneventful with no functional deficits. The use of the ALT + VL flap transabdominally is an innovative method to reconstruct exceptionally complex perineal and pelvic defects extending up to the lower back. This flap guarantees superior bulk, obliterating all pelvic dead space, with the fascia lata (FL) supporting the pelvic floor.

    Abdominoperineal resection (APR) of anorectal cancers after neoadjuvant chemoradiotherapy may incur significant perineal morbidity. While vertical rectus abdominis muscle (V-RAM) flaps can fill the pelvic resection space with health tissue, their use has previously been described predominantly in association with laparotomy. Here, we describe a means of combination laparoscopic APR with V-RAM flap reconstruction that allows structural preservation of the entire abdominal wall throughout the oncological resection and of the deep parietal layers after V-RAM donation. Furthermore, a single port access device used at the end colostomy site allows a second senior surgeon assist with an additional two working instruments for the purpose of improved pelvic tissue retraction, especially useful in obese patients.

    Full Text Available In the treatment of distal rectal cancer, abdominoperineal resection is traditionally performed. However, the recognition of shorter safe distal resection line, intersphincteric resection technique has given a chance of sphincter-saving surgery for patients with distal rectal cancer during last two decades and still is being performed as an alternative choice of abdominoperineal resection. The first aim of this study is to assess the morbidity, mortality, oncological, and functional outcomes of intersphincteric resection. The second aim is to compare outcomes of patients who underwent intersphincteric resection with the outcomes of patients who underwent abdominoperineal resection.

    This study aimed to investigate the results of salvage abdominoperineal excision (APR) in patients with persistent or recurrent squamous cell carcinoma of the anus (SCCA). Patients with anal neoplasia were identified from a prospective database. Patients with invasive SCCA with demonstrated failure of chemoradiation therapy (CRT) who underwent salvage APR for one of three disease categories (persistent,  24 months post-CRT) were included. The primary outcome was overall survival after salvage APR. Tumour size, metastatic lymph nodes (LN), circumferential resection margin positivity (CRM) and neurolymphovascular invasion (NLVI) were correlated with the outcome. Thirty-six patients with a median 3-year overall survival of 46% (median follow-up 24 months) underwent salvage APR due to persistent or recurrent SCCA (14 men, mean age 59 years). Eleven (31%) patients were diagnosed with persistent disease, 17 (47%) with early and 8 (22%) with late recurrence. Two-year overall survival of Stage 0/I/II and III/IV disease was 81.5% and 33.74%, respectively (P = 0.022). Overall disease stage was associated with disease categorization (P = 0.009): patients with persistent disease or early recurrence had a significantly higher disease stage than patients with late recurrence (OR = 20.9 and 17.2). Despite apparently improved survival in patients with late disease recurrence on live table analysis, no significant difference was identified in overall survival when stratified by disease category on log-rank test analysis. Persistent and recurrent disease does not show any significant difference in survival, but patients with late recurrence may have a better prognosis.

    To evaluate the oncological results and possible benefits associated with extralevatory abdominoperineal excision (ELAPE) when compared with conventional abdominoperineal excision (APE). ELAPE was introduced in 2007 with the purpose of reducing the rate of positive resection margins after resection of low rectal cancers. Preliminary studies have shown promising results. No large-scale or nationwide data have been presented. Database study based on data from the Danish Colorectal Cancer Group's prospective database. Data on all ELAPEs and APEs performed in Denmark in the period January 1, 2009, through August 2012 were retrieved and evaluated for differences in demography, tumor characteristics, and oncological results. Uni- and multivariate logistic regression analyses were performed to identify risk factors for resection with a positive circumferential resection margin (CRM+). A total of 554 patients were included, 301(54%) were operated by ELAPE; 253(46%) by APE. Sixty-three percent were men, median (interquartile range) age was 69 (61-76 years) years, and tumors removed had predominantly T-stages T2 and T3 (32% and 45%, respectively). Overall, CRM+ was found in 13% of patients. When divided according to type of procedure, we found no significant differences in demography and tumor T- and N-stages. Resections with a CRM+ were more common after ELAPE (16% vs 7%; P = 0.006). After uni- and multivariate logistic regression analyses, surgery by ELAPE remained a risk factor for a CRM+ [odds ratio, 2.59 (95% confidence interval, 1.31-5.12); P = 0.006). In this nationwide study, resection of low rectal cancers by ELAPE did not improve short-term oncological results, when compared with conventional APE.

    Clinical study of 14 patients with radiation colitis who were treated surgically at our clinic in the past 16-year period and a patient whose treatment was very difficult are reported. Primary lesions included 13 cervical carcinomas and one ovarian cancer. Ten cases received surgery combined with radiation and 4 did radiation. Radiation dose was 6055 rad on average. Latent time ranged from 6 months to 25 years with the average of 8 years and 9 months. No significant correlation between radiation dose and latent time was noted. Symptoms included obstruction and stenosis in 56% (8/14), hematoemesis in 46% (5/14), and fistula in 46% (5/14). All lesions presented as remarkably adhesion and stenosis, and resection with anastomosis was performed in 9 (64%), colostomy in 5 (46%), and urostomy in 2 (14%). Lumbar plasty was added in one case. A 65-year-old female patient who had undergone radiation therapy 13 years before had a rectal perforation and pelvic fistula. Abdominoperineal resection of the rectum and closure of the fistula by transferring the major gluteal muscle pedicle were performed. The patient is followed on ambulant basis for more than one year, and no evidence of recurrence has been observed. (author).

    This study was designed to explore the factors influencing local recurrence and survival for low rectal cancer with pT1-2NxM0 stage after an abdominoperineal resection (APR). Data of 429 patients confirmed to have pT1-2NxM0 after APR were reviewed. The recurrence rate in patients with intraoperative perforation, less than 12 lymph nodes (LNs) harvested, T2 staging, and positive circumferential resection margin (CRM) was 25.1, 19.9, 9.5, and 26.1% compared with 6.9, 7.0, 0, and 5.8% in patients with no perforation, 12 or more LNs harvested, T1, and negative CRM. The 5-year survival rate in patients with age of at least 70, perforation, less than 12 LNs harvested, T2, and positive CRM was 71.1, 60.8, 58.8, 69.9, and 46.0%, but 73.4, 73.5, 73.8, 89.4, and 75.0% in patients with age less than 70, no perforation, 12 or more LNs harvested, T1, and negative CRM. Meanwhile, patients with N0, N1, and N2 had a survival rate of 90.7, 69.9, and 63.9%. Multivariate analysis showed that perforation (PCRM status (P=0.002) were associated with local recurrence, whereas age of the patients (P=0.023), N staging (PCRM status (P=0.004) were associated with survival. APR was affected by patients' age, operation performer, perforation, number of LNs harvested, T staging, N staging, differentiation, and CRM status. Perforation, number of LNs harvested, T staging, differentiation, and CRM status were independent factors for recurrence; meanwhile, age of the patients, N staging, differentiation, and CRM status were independent factors influencing survival.

    Full Text Available Background. Abdominoperineal resection (APR has been associated with impaired survival in nonmetastatic rectal cancer patients. It is unclear whether this adverse outcome is due to the surgical procedure itself or is a consequence of tumor-related characteristics. Study Design. Patients were identified from the Surveillance, Epidemiology, and End Results database. The impact of APR compared to coloanal anastomosis (CAA on survival was assessed by Cox regression and propensity-score matching. Results. In 36,488 patients with rectal cancer resection, the APR rate declined from 31.8% in 1998 to 19.2% in 2011, with a significant trend change in 2004 at 21.6% (P<0.001. To minimize a potential time-trend bias, survival analysis was limited to patients diagnosed after 2004. APR was associated with an increased risk of cancer-specific mortality after unadjusted analysis (HR = 1.61, 95% CI: 1.28–2.03, P<0.01 and multivariable adjustment (HR = 1.39, 95% CI: 1.10–1.76, P<0.01. After optimal adjustment of highly biased patient characteristics by propensity-score matching, APR was not identified as a risk factor for cancer-specific mortality (HR = 0.85, 95% CI: 0.56–1.29, P=0.456. Conclusions. The current propensity score-adjusted analysis provides evidence that worse oncological outcomes in patients undergoing APR compared to CAA are caused by different patient characteristics and not by the surgical procedure itself.

    Purpose: To compare the diagnostic value of dual-phase multidetector-row CT (MDCT) and MR imaging with dual-phase three-dimensional MR angiography (MRA) in the prediction of vascular involvement and resectability of pancreatic ductal adenocarcinoma. Methods and materials: 116 patients with proven pancreatic adenocarcinoma underwent both MDCT and combined MR imaging prior to surgery. Of 116 patients, 56 who underwent surgery were included. Two radiologists independently attempt to assess detectability, vascular involvement and resectability of pancreatic adenocarcinoma on both images. Results were compared with surgical findings and statistical analysis was performed. Results: MDCT detected pancreatic mass in 45 of 56 patients (80.3%) and MR imaging in 44 patients (78.6%). In assessment of vascular involvement, sensitivities and specificities of MDCT were 61% and 96% on a vessel-by-vessel basis, respectively. Those of MR imaging were 57% and 98%, respectively. In determining resectability, sensitivities and specificities of MDCT were 90% and 65%, respectively. Those of MR imaging were 90% and 41%, respectively. There was no statistical difference in detecting tumor, assessing vascular involvement and determining resectability between MDCT and MR imaging (p = 0.5). Conclusion: MDCT and MR imaging with MRA demonstrated an equal ability in detection, predicting vascular involvement, and determining resectability for a pancreatic ductal adenocarcinoma.

    Metatarsal head resection is a common and standardized treatment used as part of the surgical routine for metatarsal head osteomyelitis. The aim of this study was to define the influence of the amount of the metatarsal resection on the development of reulceration or ulcer recurrence in patients who suffered from plantar foot ulcer and underwent metatarsal surgery. We conducted a prospective study in 35 patients who underwent metatarsal head resection surgery to treat diabetic foot osteomyelitis with no prior history of foot surgeries, and these patients were included in a prospective follow-up over the course of at least 6 months in order to record reulceration or ulcer recurrences. Anteroposterior plain X-rays were taken before and after surgery. We also measured the portion of the metatarsal head that was removed and classified the patients according the resection rate of metatarsal (RRM) in first and second quartiles. We found statistical differences between the median RRM in patients who had an ulcer recurrence and patients without recurrences (21.48 ± 3.10% vs 28.12 ± 10.8%; P = .016). Seventeen (56.7%) patients were classified in the first quartile of RRM, which had an association with ulcer recurrence (P = .032; odds ratio = 1.41; 95% confidence interval = 1.04-1.92). RRM of less than 25% is associated with the development of a recurrence after surgery in the midterm follow-up, and therefore, planning before surgery is undertaken should be considered to avoid postsurgical complications. © The Author(s) 2015.

    Full Text Available A 72-year-old female presented with a six-month history of increased frequency of defecation, rectal bleeding, and severe rectal pain. Digital rectal examination and endoscopy revealed a low rectal lesion lying anteriorly. This was confirmed histologically as adenocarcinoma. Radiological staging was consistent with a T3N2 rectal tumour. Following long-course chemoradiotherapy repeat staging did not identify any metastatic disease. She underwent a laparoscopic cylindrical abdominoperineal excision with en bloc resection of the coccyx and posterior wall of the vagina with a negative circumferential resection margin. The perineal defect was reconstructed with Permacol (biological implant, Covidien mesh. She had no clinical evidence of a perineal hernia at serial followup. Dynamic MRI images of the pelvic floor obtained during valsalva at 10 months revealed an intact pelvic floor. A control case that had undergone a conventional abdominoperineal excision with primary perineal closure without clinical evidence of herniation was also imaged. This confirmed subclinical perineal herniation with significant downward migration of the bowel and bladder below the pubococcygeal line. We eagerly await further evidence supporting a role for dynamic MR imaging in assessing the integrity of a reconstructed pelvic floor following cylindrical abdominoperineal excision.

    Although the numeric-based lymph node (LN) staging was widely used in the worldwide, it did not represent the anatomical location of metastatic lymph nodes (MLNs) and not reflect extent of LN dissection. Therefore, in the present study, we investigated whether the anatomical location of MLNs was still necessary to evaluate the prognosis of node-positive gastric cancer (GC) patients. We reviewed 1451 GC patients who underwent radical gastrectomy in our institution between January 1986 and January 2008. All patients were reclassified into several groups according to the anatomical location of MLNs and the number of MLNs. The prognostic differences between different patient groups were compared and clinicopathologic features were analyzed. In the present study, both anatomical location of MLNs and the number of MLNs were identified as the independent prognostic factors (p location of MLNs was considered (p location of MLNs had no significant effect on the prognosis of these patients, the higher number of MLNs in the extraperigastric area was correlated with the unfavorable prognosis (p location of MLNs was an important factor influencing the prognostic outcome of GC patients. To provide more accurate prognostic information for GC patients, the anatomical location of MLNs should not be ignored.

    Lymphovascular invasion (LVI) in high-grade clinical T1 bladder cancer is usually considered a poor prognostic factor, but it is often difficult to achieve correct staging of T1 bladder cancer and diagnose the presence of LVI because of the inadequacy of conventional transurethral resection specimens. The aims of this study were to evaluate the prognostic value of LVI in patients with correctly staged high-grade pathological T1 (pT1) bladder cancer who initially underwent transurethral resection in one piece (TURBO). Eighty-six high-grade pT1 bladder cancer patients who underwent TURBO were enrolled. Risk of tumor understaging was avoided by examining the vertical resection margin of the TURBO specimen. Immunohistochemical staining using D2-40 and CD31 was performed to confirm LVI. We examined the association of LVI with other clinicopathological factors and the impact of LVI on progression-free survival and cancer-specific survival. The median follow-up period was 49 months (range, 6-142). In all patients, the tumors were accurately staged as pT1 at initial TURBO. LVI was detected in 15 patients (17%) and was significantly associated with tumor growth pattern (P = 0.001). Multivariate analysis identified LVI as the only independent predictor for reduced progression-free survival (HR, 4.48; 95% CI, 1.45-13.90; P = 0.009) and cancer-specific survival (HR, 4.35; 95% CI, 1.17-16.24; P = 0.029). The presence of LVI in TURBO specimens independently predicts poor clinical outcomes in patients with high-grade pT1 bladder cancer. This information may help urologists to counsel their patients when deciding whether to choose a bladder-preserving strategy or radical cystectomy.

    Full Text Available The epithelioid sarcoma (ES is an unusual variant of the sarcoma, not reaching 1% of all soft tissue sarcomas. Initially reported in 1970, it has a more aggressive variant, which was classified as the “proximal-type” in 1997. These are aggressive tumors with high rates of distant metastasis and local relapses. Isolated radio and chemotherapy responses are poor and free-margin surgical resection is the treatment of choice.This is the case report of a 25-year-old male patient diagnosed with “proximal-type” ES in the perineal region. He underwent surgical resection in another institution and was later admitted to our institution with local recurrence with rectal and left thigh muscle invasion. Neoadjuvant radio-chemotherapy was performed, followed by laparoscopic abdominoperineal rectal resection and partial left hemipelvectomy associated with left lower-limb amputation. The patient had no postoperative complications and is currently undergoing outpatient follow-up. The anatomopathological analysis showed tumor-free margins.The “proximal-type” ES is a rare soft-tissue sarcoma subtype. High local recurrence, as well as the metastasis rates, makes its treatment a challenging task.

    Although the pepsinogen I/II (PGI/II) ratio after Helicobacter pylori eradication is recovered at short-term follow-up, long-term follow-up studies of PGI/II are rare. A total of 773 patients with gastric cancer who underwent endoscopic resection and pepsinogen and H. pylori tests were enrolled. H. pylori was eradicated in these patients. Endoscopic and pepsinogen tests were performed every year. A low PGI/II ratio was defined as ≤3. The PGI/II ratio was higher in non-infected patients (n=275, 4.99) than infected patients (n=498, 3.53). After H. pylori eradication, the PGI/II ratio increased to 5.81 and 5.63 after 1 and 2 years (each ppylori eradication group became similar to that of the H. pylori-negative group at 3 (4.48 vs. 4.34), 4 (4.88 vs. 4.34), and 5 years (4.89 vs. 4.23). The adjusted odds ratios for a lower PG I/II ratio in the non-eradication group compared to the eradication group were 4.78 (95% CI 2.15-10.67) after 1year and 8.13 (95% CI 2.56-25.83) after 2 years. After H. pylori eradication, the PGI/II ratio increased and was similar to that of H. pylori-negative controls for up to 5 years of follow-up.

    Full Text Available Vaginal agenesis is known as one of the Mόllerian anomalies. Mόllerian anomalies occur during gonadal development and differentiation, and may lead to complex outcomes. McKusick-Kaufman syndrome (MKS is an autosomal recessive multiple malformation syndrome characterized by Mόllerian anomalies with hydrometrocolpos (HMC and postaxial polydactyly (PAP. We report a case of a female newborn that developed hydronephrosis and respiratory distress due to compression of the cystic mass and underwent surgery on postpartum day 3. Pull-through vaginoplasty was performed with an abdomino-perineal approach. We report the unique treatment approach in this case.

    The role of extralevator abdominoperineal excision (ELAPE) for distal rectal cancer remains controversial, and the procedure is not widely accepted or practiced. An electronic search of Medline, EMBASE, Web of Science, and similar databases for articles in English was performed from the inception of the study until October 31, 2017. Two reviewers extracted information and independently assessed the quality of included studies by the methodological index for nonrandomized studies, then data were analyzed with Review Manager 5.3 software and Stata version 12.0 software. Our meta-analysis included 17 studies with 3479 patients, of whom 1915 (55.0%) underwent ELAPE and 1564 (44.0%) underwent abdominoperineal excision (APE). Compared with patients undergoing APE, patients undergoing ELAPE had a significant reduced risk of no more than 3 years local recurrence (LR) (risk ratio [RR] = 0.27, 95% confidence interval [CI] = 0.08-0.94), 3-year mortality (odds ratio [OR] = 0.45, 95% CI = 0.20-0.97), intraoperative bowel perforation (IBP) involvement (RR = 0.48, 95% CI = 0.31-0.74), and circumferential resection margin (CRM) positivity (RR = 0.66, 95% CI = 0.43-1.00) at the threshold level. The application of ELAPE is more effective in reducing the chance of 3 years LR, mortality, IBP involvement and CRM positivity than conventional APE, and worthy of being widely applied in surgical treatment of the distal rectal cancer.

    To investigate the safety and clinical significance of pelvic floor reconstruction in extralevator abdominoperineal excision(ELAPE) for advanced low rectal cancer. The clinical efficacy was retrospectively analyzed in 30 patients with low rectal cancer who underwent ELAPE from January 2013 to December 2016 in Nanjing Drum Tower Hospital, the affiliated Hospital of Nanjing University Medical School. There were 21 male patients and 9 female, with an average age of 61.7 years old. We used 13*15 cm Biodesign biologic meshes(Cook, China) for the reconstruction and the procedure involved soaking in saline solution for 5 minutes and fixation of the mesh to the cut edges of the levators by non-absorbable 2-0 sutures. A perineal drain was used and was removed when drainage was minimal. Potassium permanganate was used for hip bath after removing the stitches. The surgical procedure, postoperative complications, prognosis and follow-up of all these patients were documented. The operations of all patients were completed successfully. ELAPE could remove more para cancer tissues in the distant rectum. There was no rectum perforation, and the circumferential resection margins of all specimens were proved to be negative. During the follow-up of 21 months, only 2 patients suffered incision infection and healed uneventfully after strengthening the dressing. No one developed perineal breakdown, bulge or intestinal obstruction, as well as local recurrence and pelvic floor hernia. There was also no complication related to mesh. The average hospitalization time was 10 days (9-15 days). The ELAPE could render a low occurrence of intraoperative perforations and circumferential resection margins. Reconstruction of pelvic floor with biologic meshmight lower the complication incidences associated with the perineal region.

    To evaluate the efficacy of extralevator abdominoperineal excision (ELAPE) of rectal cancer. PubMed, Cochrane Library and Embase database were searched for clinical studies comparing the ELAPE and abdominoperineal excision (APE) for rectal cancer between 2007 and 2016. Two reviewers independently screened the articles and extracted the data. The Newcastle-Ottawa Scale (NOS) was used to evaluate the quality of the observational studies and the score more than 5 points was the inclusion criteria. Cochrane Handbook for Systematic Reviews of Interventions v5.1.0 was used to evaluate the quality of the randomized controlled trials (RCT). Intra-operative perforation rate, circumferential resection margin (CRM) involvement, local recurrence rate, perineal wound complications were brought into meta-analysis by Review Manager 5.3 software. A total of 556 articles were retrieved and 12 articles were enrolled finally, including 11 observational studies and 1 RCT study. All the 12 articles were high quality (scores of all observational studies were more than 11 points, RCT study accorded with 6 criteria of the quality evaluation). A total of 3 788 patients were enrolled, including 2 141 cases of ELAPE and 1 647 cases of APE. Meta-analysis revealed that intra-operative perforation rate of ELAPE was lower than APE (RR=0.52, 95%CI:0.34-0.79, P=0.002). There were no significant differences between two groups in CRM involvement (RR=0.72, 95%CI:0.49-1.07, P=0.10), local recurrence rate (OR=0.55, 95%CI:0.24-1.29, P=0.17) and perineal wound complications (RR=0.94, 95%CI:0.58-1.53, P=0.800). Compared with APE, ELAPE reduces the intra-operative perforation rate, and does not increase the perineal wound complications, but it has no advantages in decreasing the CRM involvement and local recurrence rate.

    Full Text Available Abstract Background Primary closure of the perineum with drainage after abdominoperineal excision of the rectum for carcinoma, is widely accepted. However hematoma, perineal abscess and re-operation are significantly more frequent after primary closure than after packing of the perineal cavity. Those complications are frequently related to the patients' clinical antecedent (i.e radiotherapy, diabetes, smoking. Case presentation In the present report, vacuum assisted drainage was used after abdominoperineal excision for carcinoma in the very first step due to intraoperative gross septic contamination during tumor resection. The first case: A 57-years old man with a 30-years history of peri-anal Crohn's disease, the adenocarcinoma of the lowest part of the rectum and Crohn colitis with multiple area of severe dysplasia required panproctocolectomy with a perineal resection. The VAC system was used during 12 days (changed every 3 days. We observed complete healing 18 days after surgery. The second case: A 51-year-old man, with AIDS. An abdominoperineal resection was performed for recurrence epidermoid anal cancer. The patient was discharged at day 25 and complete healing was achieved 30 days later after surgery. Conclusion The satisfactory results showed in the present report appear to be favored by association of omentoplasty and VAC system. Those findings led us to favor VAC system in the case of pelvic exenteration associated with high risk of infection.

    Perineal wound healing is a significant challenge after extralevator abdominoperineal excision (ELAPE) due to a high rate of wound breakdown. Negative pressure therapy has proven benefits in open wounds, and recently a negative pressure system has been developed for use on closed wounds at high risk of breakdown, such as apronectomy and hysterectomy. The aim of the present study was to determine whether negative pressure therapy applied to closed perineal wounds after ELAPE improved wound healing and compare outcomes to the published literature and outcomes from a historical cohort of patients who had undergone 'standard' abdominoperineal resection (APR) and primary closure of the perineal wounds. Prospective data on consecutive patients having ELAPE in the period from November 2012 to April 2015 were collected. The pelvic floor defect was reconstructed with biologic mesh. The adipose tissue layer was closed with vicryl sutures, a suction drain was left in the deep layer, the subcuticular layer and skin were closed, and the negative pressure system was applied. Any wound breakdown within the first 30 days postoperatively was recorded. Of the 32 consecutive ELAPE patients whose perineal wounds were closed within 30 days with the use of the negative pressure system, there was 1 patient with major perineal wound breakdown and 2 patients with a 1 cm superficial wound defect, which needed no further treatment. In the remaining 29 (90 %) patients, the perineal wounds healed fully without complications. Twenty-five patients underwent standard APR in 2010-2011 with primary closure of their perineal wounds. Ten out of 25(40 %) of patients who had undergone standard APR and primary closure of perineal wounds had major wound complications (p = 0.01). Our results suggest that after ELAPE the application of a negative pressure system to the perineal wound closed with biologic mesh may reduce perineal wound complications and may reduce the need for major perineal

    Abdominoperineal excision of the rectum (APER) for cancer has been associated with higher circumferential resection margin (CRM) involvement and failure of local disease control. The aim of this study was to investigate whether the introduction of laparoscopic APER altered the incidence of CRM involvement. Consecutive patients undergoing open or laparoscopic APER for adenocarcinomas of the rectum were studied. Patient demographics, preoperative staging, neoadjuvant treatment, operative findings, length of stay and pathological details were collected from operative and radiology databases and compared. There were 16 laparoscopic and 25 open APER performed over a 3-year period. Neoadjuvant therapy was given to 43.8% (7/16) of the laparoscopic group and 56.0% (14/25) of the open group. Complete laparoscopic resection was possible in 14 (87.5%) of 16 patients. The median harvested number of nodes was 14 (4-33) in both groups. The median length of stay was 7 (3-13) and 15 (9-40) days in the laparoscopic and open groups (P CRM was clear in all cases. There was no local recurrence in either group at a median follow-up of 23 months. There were no in-hospital deaths and no significant differences in overall survival. There were no significant differences in preoperative or postoperative histopathological T stage between the two groups (P = 0.057 and P = 0.121). Laparoscopic APER for selected rectal cancers can achieve comparable oncological outcome to open surgery but is associated with a much shorter length of stay. Patient and tumour characteristics must be taken into consideration when deciding on a laparoscopic approach for low rectal cancer. © 2011 The Authors.

    An involved circumferential resection margin (CRM) following surgery for rectal cancer is the strongest predictor of local recurrence and may represent a failure of the multidisciplinary team (MDT) process. The study analyses the causes of positive CRM in patients undergoing elective surgery for rectal cancer with respect to the decision-making process of the MDT, preoperative rectal cancer staging and surgical technique. From March 2002 to September 2005, data were collected prospectively on all patients undergoing elective rectal cancer surgery with curative intent. The data on all patients identified with positive CRM were analysed. Of 158 patients (male:female = 2.2:1) who underwent potentially curative surgery, 16 (10%) patients had a positive CRM on postoperative histology. Four were due to failure of the pelvic magnetic resonance imaging (MRI) staging scans to predict an involved margin, two with an equivocal CRM on MRI did not have preoperative radiotherapy, one had an inaccurate assessment of the site of primary tumour and in one intra-operative difficulty was encountered. No failure of staging or surgery was identified in the remaining eight of the 16 patients. Abdominoperineal resection (APR) was associated with a 26% positive CRM, compared with 5% for anterior resection. No single consistent cause was found for a positive CRM. The current MDT process and/or surgical technique may be inadequate for low rectal tumours requiring APR.

    The impact of in vitro chemosensitivity test-guided platinum-based adjuvant chemotherapy on the surgical outcomes of patients undergoing complete resection for locally advanced non-small cell lung cancer (NSCLC) has yet to be elucidated. In the present study, the utility of adjuvant chemotherapy based on the collagen gel droplet embedded culture drug sensitivity test (CD-DST) in patients with p (pathology)-stage IIIA NSCLC was retrospectively analyzed. A series of 39 patients that had received platinum-based adjuvant chemotherapy following complete resection between 2007 and 2012 were enrolled. Their surgical specimens were subjected to the CD-DST. The patients were subsequently classified into two groups on the basis of in vitro anti-cancer drug sensitivity data obtained using the CD-DST: The sensitive group (25 patients) were treated with regimens including one or two of the anti-cancer drug(s) that were indicated to be effective by the CD-DST, whereas the non-sensitive group (14 patients) were treated with chemotherapy regimens that did not include any CD-DST-selected anti-cancer drugs. There were no significant differences in the background characteristics of the two groups [including in respect of the pathological TN (tumor-lymph node) stage, tumor histology, epidermal growth factor receptor mutation status, the frequency of each chemotherapy regimen, and the number of administered cycles]. The 5-year disease-free survival (DFS) rate of the sensitive group was 32.3%, whereas that of the non-sensitive group was 14.3% (P=0.037). In contrast, no difference in overall survival (OS) was observed (P=0.76). Multivariate analysis revealed that adjuvant chemotherapy based on the CD-DST had a significant favorable effect on the DFS (P=0.01). Therefore, the present study has demonstrated that CD-DST data obtained from surgical specimens aid the selection of effective platinum-based adjuvant chemotherapy regimens for patients undergoing complete resection for p-stage IIIA

    Full Text Available Laparoscopic colon resection has established its role as a minimally invasive approach to colorectal diseases. Better long-term survival rate is suggested to be achievable with this approach in colon cancer patients, whereas some doubts were raised about its safety in rectal cancer. Here we report on our single centre experience of rectal laparoscopic resections for cancer focusing on short- and long-term oncological outcomes. In the last 13 years, 248 patients underwent minimally invasive approach for rectal cancer at our centre. We focused on 99 stage I, II, and III patients with a minimum follow-up period of 5 years. Of them 43 had a middle and 56 lower rectal tumor. Laparoscopic anterior rectal resection was performed in 71 patients whereas laparoscopic abdomino-perineal resection in 28. The overall mortality rate was 1%; the overall morbidity rate was 29%. The 5-year disease-free survival rate was 69.7%, The 5-year overall survival rate was 78.8%.

    The aims of this study were to assess the feasibility of performing an extralevator abdominoperineal excision (ELAPE) after neoadjuvant chemoradiation (NCRT), to compare the rates of circumferential resection margin (CRM) involvement and intra-operative perforation (IOP) of the specimen, and to assess the amount of tissue removed around the muscularis propria (MP)/internal sphincter (IS) of the lower rectum in patients with low rectal cancer undergoing ELAPE compared with conventional abdominoperineal excision (CAPE) after NCRT. This was an open-label, parallel-arm pilot randomized trial conducted in India. Twenty patients were randomized to one of the study arms. The surgical specimens were fixed, serially cross-sectioned and photographed. Using specialized morphometry software, the amount of tissue resected with each operation was measured. There was a nonsignificant trend towards more IOPs (30% vs 0%, P = 0.06) and a higher CRM involvement rate (40% vs 20%, P = 0.32) in the CAPE arm. ELAPE removed a significantly greater amount of tissue around the IS/MP when compared with CAPE (mean ± SD: 1911.39 ± 382 mm 2 vs 1132.03 ± 371 mm 2 , P CRM was significantly greater in the ELAPE arm both in the posterior (mean ± SD: 28.28 ± 3 mm vs 9.63 ± 3 mm, P CRM involvement when compared with CAPE, even after NCRT.

    The goal of rectal cancer treatment is to minimize the local recurrence rate and extend the disease-free survival period and survival. For this aim, obtainment of negative circumferential radial margin (CRM) plays an important role. This study evaluated predictive factors for positive CRM status and its effect on patient survival in mid- and distal rectal tumors.Patients who underwent curative resection for rectal cancer were included. The main factors were demographic data, tumor location, surgical technique, neoadjuvant therapy, tumor diameter, tumor depth, lymph node metastasis, mesorectal integrity, CRM, the rate of local recurrence, distant metastasis, and overall and disease-free survival. Statistical analyses were performed by using the Chi-squared test, Fisher exact test, Student t test, Mann-Whitney U test and the Mantel-Cox log-rank sum test.A total of 420 patients were included, 232 (55%) of whom were male. We observed no significant differences in patient characteristics or surgical treatment between the patients who had positive CRM and who had negative CRM, but a higher positive CRM rate was observed in patients undergone abdominoperineal resection (APR) (P CRM status. Logistic regression analysis revealed that APR (P CRM status. Moreover, positive CRM was associated with decreased 5-year overall and disease-free survival (P = 0.002 and P = 0.004, respectively).This large single-institution series demonstrated that APR and open resection were independent predictive factors for positive CRM status in rectal cancer. Positive CRM independently decreased the 5-year overall and disease-free survival rates.

    Rectal GI stromal tumor is uncommon. Local excision with free resection margins provides adequate treatment, but extended surgery such as abdominoperineal resection has been frequently performed because of technical difficulties in the confined pelvic space. We aimed to report the technical details of a new method of local excision for rectal GI stromal tumor: the modified laparoscopic intersphincteric resection technique. This study was a retrospective analysis. This study was performed at a single institute. We included 3 patients with rectal GI stromal tumor who underwent this procedure following neoadjuvant imatinib therapy. Medial-to-lateral retroperitoneal dissection was begun near the sacral promontory, and rectal dissection while preserving autonomic nerves was performed down to the pelvic floor into the anal canal without dividing the inferior mesenteric artery. Dissection between the tumor and prostate was meticulously performed under laparoscopic magnified view. Next, circumferential connection between the laparoscopic and transanal dissections was performed through a transanal approach, and the rectum was extracted through the anus. Circular full-thickness local excision of the rectum and handsewn straight rectoanal anastomosis was performed. The safety and feasibility of this procedure were the primary outcomes measured by this study. The median operative time was 180 minutes, and the median estimated blood loss was 115 mL. There were no conversions or intraoperative complications, and there was 1 postoperative intestinal obstruction that recovered with conservative therapy. All patients had negative resection margins (R0), including 1 pathological complete response. The study was limited by the small number of patients. This modified laparoscopic intersphincteric resection technique is a novel and safe method for local excision of rectal GI stromal tumors located very close to the anus (see Video, Supplemental Digital Content 1, http

This study aims to evaluate the quality of life of patients underwent laparoscopic and open colorectal resections in the early postoperative period. METHODS: this is a prospective study which evaluated 42 patients underwent laparoscopic and open colorectal resection between May to November 2008 followed up until 60th postoperative day. Questionnaires of quality of life were applied in 3th, 7th and 30th postoperative days. Statistical analysis consisted of descriptive analysis of global healthy status scores, functional scores and symptoms of EORTC/QLQ 30. Shapiro-Wilk, Mann-Whitney e t de Student statistical tests were used to check the data, with level of significance in 0.05. RESULTS: Most of patients were females (57.1% with mean age of 61.5 years. It was observed significant difference of "global health status" score on the 30th postoperative between groups, with values of 75.0 and 58.3 for patients underwent laparoscopic and open procedures respectively (p = 0.005. There were no differences in terms of physical function and others as, accomplishment, emotional, cognitive and social functions. In relation to symptoms (fatigue, nausea, pain, dyspnea, insomnia, loss of appetite and constipation and financial difficulties, there were also no differences between groups. CONCLUSION: Our results have demonstrated that patients underwent laparoscopic colorectal resections have better quality of life at the end of first postoperative month when compared to patients underwent to open colorectal resections.

    Compared with single-incision laparoscopy, multiport laparoscopy is associated with greater risk of postoperative wound pain, infection, incisional hernias, and suboptimal cosmetic outcomes. The feasibility of minimally invasive single-incision laparoscopic surgery (SILS) for colorectal procedures is well-established, but outcome data remain limited. Patients with benign diverticular disease, Crohn's disease, or ulcerative colitis admitted to Klinikum Leverkusen, Germany, for colonic resection between July 2009 and March 2011 (n = 224) underwent single-incision laparoscopic surgery using the SILS port system. Surgeons had ≥7 years' experience in laparoscopic colon surgery but no SILS experience. Patient demographic and clinical data were collected prospectively. Pain was evaluated by using a visual analog scale (0-10). Data were analyzed by using the SPSS PASW Statistics 18 database. The majority of patients underwent sigmoid colectomy with high anterior resection (AR) or left hemicolectomy (n = 150) for diverticulitis. Our conversion rate to open surgery was 6.3 %, half in patients undergoing sigmoid colectomy with high AR or left hemicolectomy, 95 % of whom had diverticulitis. Mean operating time was 166 ± 74 (range, 40-441) min in the overall population, with shorter times for single-port transanal tumor resection (SPTTR; 89 ± 51 min; range, 40-153 min) and longer times for proctocolectomy (325 min; range, 110-441 min). Mean hospital stay was approximately 10 days, longer after abdominoperineal rectal resection or proctocolectomy (12-16 days). Most complications occurred following sigmoid colectomy with high AR or left hemicolectomy [19/25 (76 %) of early and 4/5 (80 %) of late complications, respectively]. Pain was surgery, conducted by experienced laparoscopic surgeons without specific training in use of the SILS port.

    Few investigations of robot-assisted intersphincteric resection (ISR) are presently available to support this procedure as a safe and efficient procedure. We aimed to evaluate the utility of robot-assisted ISR by comparison between ISR and abdominoperineal resection (APR) using both robot-assisted and open approaches. The 558 patients with lower rectal cancer (LRC) who underwent curative operation was enrolled between July 2010 and June 2015 to perform either by robot-assisted (ISR vs. APR = 310 vs. 34) or open approaches (144 vs. 70). Perioperative and functional outcomes including urogenital and anorectal dysfunctions were measured. Recurrence and survival were examined in 216 patients in which >3 years had elapsed after the operation. The robot-assisted approach was the most significant parameter to determine ISR achievement among potent parameters (OR = 3.467, 95% CI = 2.095-5.738, p robot-assisted ISR at 12 and 24 months, respectively (p robot-assisted ISR replaced a significant portion of APR to achieve successful SSO via mostly transabdominal approach and double-stapled anastomosis. The robot-assisted ISR with minimal invasiveness might be a help to reduce anorectal and urogenital dysfunctions.

    Full Text Available IntroductionThe aim of this review is to provide an overview of the evidence for the use of biologic mesh in the reconstruction of the pelvic floor after extralevator abdominoperineal excision of the rectum (ELAPE.MethodsA systematic search of PubMed was conducted using the search terms ‘ELAPE’, ‘extralevator abdominoperineal excision of rectum’ or ‘extralevator abdominoperineal resection’. The search yielded 17 studies.ResultsBiologic mesh was used in perineal reconstruction in 463 cases. There were 41 perineal hernias reported but rates were not consistently reported in all studies. The most common complications were perineal wound infection (n = 93, perineal sinus and fistulae (n = 26 and perineal haematoma or seroma (n = 11. There were very few comparative studies, with only one RCT identified that compared patients undergoing ELAPE with perineal reconstruction using a biological mesh, with patients undergoing a conventional abdominoperineal excision of the rectum with no mesh. There was no significant difference in perineal hernia rates or perineal wound infections between the groups. Other comparative studies comparing the use of biologic mesh with techniques such as the use of myocutaneous flaps were of low quality.ConclusionsBiologic mesh-assisted perineal reconstruction is a promising technique to improve wound healing and has comparable complications rates to other techniques. However, there is not enough evidence to support its use in all patients who have undergone ELAPE. Results from high-quality prospective RCTs and national/international collaborative audits are required.

    Lateral spreading tumors (LST) are relatively large flat lesions with diameters exceeding 10 mm in length. Endoscopic mucosal resection (EMR) is a commonly used technique for removing LST. We aimed to evaluate the risk factors for incomplete resection and complications of EMR for LST. Between January 2004 and December 2010, 497 patients who underwent EMR for LST were retrospectively reviewed. Risk factors for endoscopic and histopathological complete resection, complications, and clinical outcomes were investigated. Risks for incomplete resection by piecemeal resection and en bloc resection of a lesion ≥ 30 mm were higher than for en bloc resection of a lesion LST ≥ 30 mm, hospitalize patients for 12 h and note risk for incomplete resection. (iii) Following en bloc resection for LST<30 mm, hospitalize the patient for 12 h and expect complete resection. © 2012 The Authors.

    Intersphincteric resection has become a widely used treatment for patients with rectal cancer. However, the detailed anatomy of the anal canal related to this procedure has remained unclear. The purpose of this study was to clarify the detailed anatomy of the anal canal. This is a descriptive study. Histologic evaluations of paraffin-embedded tissue specimens were conducted at a tertiary referral hospital. Tissue specimens were obtained from cadavers of 5 adults and from 13 patients who underwent abdominoperineal resection for rectal cancer. Sagittal sections from 9 circumferential portions of the cadaveric anal canal (histologic staining) and 3 circumferential portions from patients were studied (immunohistochemistry for smooth and skeletal muscle fibers). Longitudinal fibers between the internal and external anal sphincters consisted primarily of smooth muscle fibers that continued from the longitudinal muscle of the rectum. The levator ani muscle attached directly to the lateral surface of the longitudinal smooth muscle of the rectum. The length of the attachment was longer in the anterolateral portion and shorter in the posterior portion of the anal canal. In the lateral and posterior portions, the levator ani muscle partially overlapped the external anal sphincter; however, there was less overlap in the anterolateral portion. In the posterior portion, thick smooth muscle was present on the surface of the levator ani muscle and it continued to the longitudinal muscle of the rectum. We observed only limited portions in some surgical specimens because of obstruction by tumors. The levator ani muscle attaches directly to the longitudinal muscle of the rectum. The spatial relationship between the smooth and skeletal muscles differed in different portions of the anal canal. For intersphincteric resection, dissection must be performed between the longitudinal muscle of the rectum and the levator ani muscle/external anal sphincter, and the appropriate surgical lines

    Extra-levator abdominoperineal excision (APE) of the rectum has been introduced with the aim of improving the oncological outcome of low rectal cancer. The procedure includes resection of the levator muscles en bloc with the mesorectum, leaving a larger perineal defect than after conventional APE. This study reports short-term outcome of gluteus maximus myocutaneous flap reconstruction on perineal wound healing. Sixty-five patients were studied after extra-levator APE and a one-sided myocutaneous flap for a low or locally recurrent rectal cancer at the Karolinska University Hospital from January 2002 to December 2008. Fifty-nine had received neoadjuvant radio- or radiochemotherapy. All perineal complications occurring within 30 days after surgery were registered. In addition, the status of the perineal reconstruction at 6 months and 1 year after surgery was assessed based on medical records from outpatient visits. Twenty-seven (41.5%) patients had one or more perineal wound complications. A minor wound infection occurred in 15, while 12 had either a more severe infection with dehiscence or a pelvic abscess. The reconstruction was completely healed in 91% of the patients at 1 year. Although the vast majority of the perineal reconstructions were healed at 1 year, the short-term perineal wound complication rate of gluteus maximus flap reconstruction was high. © 2011 The Authors.

    Between 1975 and 1990, 525 patients underwent resection of colorectal cancer in our unit. Of these, 38 had tumour invading adjacent structures and underwent an extended resection. Overall, there were 67 cases treated palliatively. Of these, three were in the group of 38 having an extended resection. When the groups of radical not extended (n = 423) and radical extended resections (n = 35) were compared, respective values for mortality (1.9% vs 0) and morbidity (12.8% vs 11.3%) were not different. Respective local recurrence rates (13% vs 26%) were significantly greater after extended resection. Five-year survival after extended resection was 30%, no different from the general survival rate for standard resections for T2-3 node-positive tumours. Extended resection is thus a safe and important approach for locally advanced tumours.

    Dissection of the perineal body (PB) during abdominoperineal excision (APE) for low rectal cancer is often difficult due to the lack of a natural plane of dissection. Understanding the PB and its relation to the anorectum is essential to permit safe dissection during the perineal phase of the operation and avoid damage to the anorectum and urogenital organs. This study describes the anatomy and histology of the PB relevant to APE. Six human adult cadaver pelvic exenteration specimens (three male, three female) from the Leeds GIFT Research Tissue Programme were studied. Paraffin-embedded mega-blocks were produced and serially sectioned at 50- and 250-μm intervals. Sections were stained by immunohistochemistry to show collagen, elastin and smooth muscle. The PB was cylindrically shaped in the male specimens and wedge-shaped in the female ones. Although centrally located between the anal and urogenital triangles, it was nearly completely formed by muscle fibres derived from the rectal muscularis propria. Thick bundles of smooth muscle, mostly arising from the longitudinal muscle, inserted into the PB and levator ani muscle (LAM). The recto-urethralis muscle originated from the PB and separated the anterolateral PB from the urogenital organs. Smooth muscle fibres derived from the rectal muscularis propria extend into the PB and LAM and appear to fix the anorectum. Dissection of the PB during APE is safe only when the smooth muscle fibres that extend into the PB are divided.

    We investigated the safety of simultaneous bilateral lung resection for lung metastases. We retrospectively analyzed 185 patients with pulmonary metastases who underwent unilateral or bilateral pulmonary resection from August 2009 to December 2016 at a single institution. Single-stage bilateral lung resection was undertaken in 19 patients, and the other 166 patients underwent unilateral pulmonary resection, including 20 patients who underwent repeated resections for synchronous or metachronous metastases. Operative time and drainage days in the bilateral group were significantly longer than those in the unilateral group (220±20 vs. 152±6.9 min: ppulmonary metastasectomy appears to be safe as long as only wedge resection is performed on at least one side.

    Full Text Available Abstract Background Pancreatic adenocarcinoma (PCA is one of the most lethal human malignancies, and radical surgery remains the cornerstone of treatment. After resection, the overall 5-year survival rate is only 10% to 29%. At the time of presentation, however, about 40% of patients generally have distant metastases and another 40% are usually diagnosed with locally advanced cancers. The remaining 20% of patients are indicated for surgery on the basis of the results of preoperative imaging studies; however, about half of these patients are found to be unsuitable for resection during surgical exploration. In the current study, we aimed to determine the clinicopathological characteristics that predict the resectability of PCA and to conduct a prognostic analysis of PCA after resection to identify favorable survival factors. Methods We retrospectively reviewed the medical files of 688 patients (422 men and 266 women who had undergone surgery for histopathologically proven PCA in the Department of Surgery at Chang Gung Memorial Hospital in Taiwan from 1981 to 2006. We compared the clinical characteristics of patients who underwent resection and patients who did not undergo resection in order to identify the predictive factors for successful resectability of PCA, and we conducted prognostic analysis for PCA after resection. Results A carbohydrate antigen 19–9 (CA 19–9 level of 37 U/ml or greater and a tumor size of 3 cm or more independently predicted resectability of PCA. In terms of survival after resection, PCA patients with better nutritional status (measured as having an albumin level greater than 3.5 g/dl, radical resection, early tumor stage and better-differentiated tumors were associated with favorable survival. Conclusions Besides traditional imaging studies, preoperative CA 19–9 levels and tumor size can also be used to determine the resectability of PCA. Better nutritional status, curative resection, early tumor stage and well

    2014-01-01

    Background Complete resection of the thymus is considered appropriate for a thymoma resection because any remaining thymic tissue can lead to local recurrence. However, there are few studies concerning the extent of thymus resection. Therefore, we conducted a retrospective study to investigate whether recurrence following thymoma resection correlated to the extent of resection. Methods Between 1986 and 2011, a total of 491 patients underwent resection of thymic epithelial tumors with curative intent. Of those, we excluded patients with an undetermined World Health Organization (WHO) histologic type, patients with type C thymoma, and patients who underwent incomplete resection (n = 21). The remaining 342 patients were reviewed retrospectively and compared recurrence according to the extent of resection. Results Extended thymectomy was performed in 239 patients (69.9%) and limited thymectomy was performed 103 patients (30.1%). In the extended thymectomy group, 29 recurrences occurred, and in the limited thymectomy group, 10 recurrences occurred. Comparing rates of freedom from recurrence between two groups, there was no significant statistical difference in total recurrence (p =0.472) or local recurrence (p =0.798). After matching patients by stage and tumor size, there was no significant difference in freedom from recurrence between the two groups (p = 0.162). Additionally, after adjusting for histologic type and MG, there was also no significant difference (p = 0.125) between groups. Conclusions No difference in the rate of recurrence was observed in patients following limited thymectomy compared with extended thymectomy. PMID:24646138

    Changes in motor function occur in the intestinal remnant after intestinal resection. Smooth muscle adaptation also occurs, particularly after extensive resection. The time course of these changes and their interrelationship are unclear. Our aim was to evaluate changes in canine smooth muscle structure and function during intestinal adaptation after transection and resection. Twenty-five dogs underwent either transection (N = 10), 50% distal resection (N = 10), or 50% proximal resection (N = 5). Thickness and length of the circular (CM) and longitudinal (LM) muscle layers were measured four and 12 weeks after resection. In vitro length-tension properties and response to a cholinergic agonist were studied in mid-jejunum and mid-ileum. Transection alone caused increased CM length in the jejunum proximal to the transection but did not affect LM length or muscle thickness. A 50% resection resulted in increased length of CM throughout the intestine and thickening of CM and LM near the anastomosis. Active tension of jejunal CM increased transiently four weeks after resection. Active tension in jejunal LM was decreased 12 weeks after transection and resection. Sensitivity of CM to carbachol was similar after transection and resection. It is concluded that: (1) Structural adaptation of both circular and longitudinal muscle occurs after intestinal resection. (2) This process is influenced by the site of the intestinal remnant. (3) Only minor and transient changes occur in smooth muscle function after resection. (4) Factors other than muscle adaptation are likely involved in the changes in motor function seen following massive bowel resection.

    This study compares the use of a standard 7 mm resection length to a variable 4:1 ratio of resection length to desired elevation nomogram when performing Muller's muscle conjunctival resection surgery. In this cross-sectional case control study, 2 groups were defined. The first underwent Muller's muscle conjunctival resection surgery with a standard 7 mm resection length and the second underwent the same surgery with a variable resection length determined by a 4:1 ratio of resection length to desired elevation nomogram. Groups were matched for age (within 5 years) and sex. Pre- and postoperative photographs were measured digitally. Change in upper marginal reflex distance 1 (MRD1) and final MRD1 were the primary outcome measures. The study was powered to detect a 1 mm difference in MRD1 to a beta error of 0.95. No significant preoperative differences between the groups were noted. No significant difference in final MRD1 (0.1 mm; p = 0.74) or change in MRD1 (0.2 mm; p = 0.52) was noted. Mean resection length to elevation ratios were 3.9:1 for standard group and 4.3:1 for the variable group (p = 0.54). The authors were not able to detect a significant difference in final MRD1 or change in MRD1 for patients undergoing Muller's muscle conjunctival resection surgery with standard or variable resection lengths. These results tend to argue against a purely mechanical mechanism for Muller's muscle conjunctival resection surgery.

    Reports on laparoscopic liver resection for intrahepatic cholangiocarcinoma are still scarce. With increased experience in laparoscopic liver resection, its application to intrahepatic cholangiocarcinoma can now be considered. Our aim is to determine the feasibility and safety of laparoscopic liver resection for intrahepatic cholangiocarcinoma and to analyze its clinical and oncologic outcomes. Among the 84 patients with intrahepatic cholangiocarcinoma operated on from March 2004 to April 2012, 37 patients with a T-stage of 2b or less were included in the study. Eleven patients underwent laparoscopic liver resection, and 26 underwent open liver resection. Treatment and survival outcomes were analyzed. Intraoperative blood loss was significantly greater in the open group (P=.024), but with no difference in the blood transfusion requirement between groups (P=.074), and no operative mortality occurred. The median operative time, postoperative resection margin, and length of hospital stay were comparable between groups (P=.111, P=.125, and P=.077, respectively). Four (36.4%) patients in the laparoscopic group developed recurrence compared with 12 (46.2%) patients in the open group (P=.583). After a median follow-up of 17 months, the 3- and 5-year overall survival rates were 77.9% and 77.9%, respectively, in the laparoscopic group compared with 66.2% and 66.2%, respectively, in the open group (P=.7). There was also no significant difference in the 3- and 5-year disease-free survival rates for the laparoscopic group at 56.2% and 56.2%, respectively, versus the open group at 39.4% and 39.4%, respectively (P=.688). Laparoscopic liver resection for intrahepatic cholangiocarcinoma is technically safe with survival outcome comparable to that of open liver resection in selected cases.

    Laparoscopic colon resection (LCR) has been performed in the United States sine 1990. This procedure has been accepted by many as a reasonable alternative for nonmalignant, colonic, surgical disease, but the laparoscopic approach remains controversial for curative treatment of carcinoma. In this paper, the results of a nonrandomized series of two large experiences of laparoscopic colon resections were performed and followed for 3 1/2 years in a prospective fashion against an equal number of patients who underwent open resection. The setting was several large metropolitan hospitals in San Antonio, Texas. Over 194 patients were involved in this study. Each patient once diagnosed with resectable colonic cancer was allowed to choose their own procedure, laparoscopic or open colon resection, either of which was performed by the authors. Factors considered include age, sex, body habitus, stage of cancer, margins of resection, numbers of lymph nodes retrieved, hospitalization time, and follow-up period. Observations at this time indicate the following: (1) LCR allows for resection comparable to the classical approach, (2) equal numbers of mesenteric lymph nodes can be retrieved, (3) adequacy of margins of resection can be accurately determined by colonoscopy during LCR, and (4) brief follow-up periods show comparable survival and disease-free intervals. It is the conclusion of the authors that with proper training LCR will come to be recognized as a safe, effective surgical option for treatment of selected patients with colon cancer.

    Full Text Available Primary pancreatic small cell carcinoma (SCC is rare, with just over 30 cases reported in the literature. Only 7 of these patients underwent surgical resection with a median survival of 6 months. Prognosis of SCC is therefore considered to be poor, and the role of adjuvant therapy is uncertain. Here we report two institutions’ experience with resectable pancreatic SCC. Six patients with pancreatic SCC treated at the Johns Hopkins Hospital (4 patients and the Mayo Clinic (2 patients were identified from prospectively collected pancreatic cancer databases and re-reviewed by pathology. All six patients underwent a pancreaticoduodenectomy. Clinicopathologic data were analyzed, and the literature on pancreatic SCC was reviewed. Median age at diagnosis was 50 years (range 27-60. All six tumors arose in the head of the pancreas. Median tumor size was 3 cm, and all cases had positive lymph nodes except for one patient who only had five nodes sampled. There were no perioperative deaths and three patients had at least one postoperative complication. All six patients received adjuvant therapy, five of whom were given combined modality treatment with radiation, cisplatin, and etoposide. Median survival was 20 months with a range of 9-173 months. The patient who lived for 9 months received chemotherapy only, while the patient who lived for 173 months was given chemoradiation with cisplatin and etoposide and represents the longest reported survival time from pancreatic SCC to date. Pancreatic SCC is an extremely rare form of cancer with a poor prognosis. Patients in this surgical series showed favorable survival rates when compared to prior reports of both resected and unresectable SCC. Cisplatin and etoposide appears to be the preferred chemotherapy regimen, although its efficacy remains uncertain, as does the role of combined modality treatment with radiation.

    Full Text Available Aim: Pediatric lung resection is a relatively uncommon procedure that is usually performed for congenital lesions. In recent years, thoracoscopic resection has become increasingly popular, particularly for small peripheral lesions. The aim of this study was to review our experience with traditional open lung resection in order to evaluate the existing "gold standard." Materials and Methods: We carried out a retrospective analysis of all children having lung resection for congenital lesions at our institution between 1997 and 2004. Data were collected from analysis of case notes, operative records and clinical consultation. The mean follow-up was 37.95 months. The data were analyzed using SPSS. Results: Forty-one children (13 F/28 M underwent major lung resections during the study period. Their median age was 4.66 months (1 day-9 years. The resected lesions included 21 congenital cystic adenomatoid malformations, 14 congenital lobar emphysema, four sequestrations and one bronchogenic cyst. Fifty percent of the lesions were diagnosed antenatally. Twenty-six patients had a complete lobectomy while 15 patients had parenchymal sparing resection of the lesion alone. Mean postoperative stay was 5.7 days. There have been no complications in any of the patients. All patients are currently alive, asymptomatic and well. None of the patients have any significant chest deformity. Conclusions: We conclude that open lung resection enables parenchymal sparing surgery, is versatile, has few complications and produces very good long-term results. It remains the "gold standard" against which minimally invasive techniques may be judged.

    Studies addressing the role of mechanical bowel preparation (MBP) in Crohn's disease (CD) patients are lacking. Consecutive elective colorectal resections for CD have been included in the present analysis. Exclusion criteria were small bowel resections not including colon, urgent surgeries, surgeries for cancer, and abdominoperineal resections for perianal disease. MBP was performed routinely between 1992 and 2004, omitted between 2005 and 2015, and reintroduced in 2016.Intraabdominal septic complications (IASC) were anastomotic leakage, intraabdominal abscess, intestinal fistula, and peritonitis. Overall, 680 bowel resections for CD have been performed between 1992 and 2017. After exclusion of the abovementioned patients, 549 patients were included in the present analysis. The IASC rate was 12% in patients undergoing surgery after MPB as opposed to 24% when MBP was omitted (P < 0.001). By the multivariate analysis, preoperative MBP significantly reduced the risk of IASC (Hazard ratio 0.45; 95% CI, 0.23 - 0.86; P = 0.016). Preoperative weight loss (HR 2.0; 95% CI, 1.1 - 3.6; P = 0.024), penetrating disease (HR 2.6; 95% CI, 1.3 - 5.4; P = 0.01), and stapled as opposed to hand-sewn ileocolic anastomosis (HR 3.3; 95% CI, 1.4 - 7.7; P = 0.006) were associated with an increased risk of IASC. The positive impact of MBP was strongest on anastomotic complication rate in patients undergoing ileocolic resections for penetrating disease (11% vs 36%, P < 0.001). Preoperative MPB should be strongly considered before colorectal surgery in patients with CD, especially in patients undergoing ileocolic resections for penetrating disease.

    Endoscopic resection of duodenal non-lifting adenomas and subepithelial tumors is challenging and harbors a significant risk of adverse events. We report on a novel technique for duodenal endoscopic full-thickness resection (EFTR) by using an over-the-scope device. Data of 4 consecutive patients who underwent duodenal EFTR were analyzed retrospectively. Main outcome measures were technical success, R0 resection, histologic confirmation of full-thickness resection, and adverse events. Resections were done with a novel, over-the-scope device (full-thickness resection device, FTRD). Four patients (median age 60 years) with non-lifting adenomas (2 patients) or subepithelial tumors (2 patients) underwent EFTR in the duodenum. All lesions could be resected successfully. Mean procedure time was 67.5 minutes (range 50-85 minutes). Minor bleeding was observed in 2 cases; blood transfusions were not required. There was no immediate or delayed perforation. Mean diameter of the resection specimen was 28.3 mm (range 22-40 mm). Histology confirmed complete (R0) full-thickness resection in 3 of 4 cases. To date, 2-month endoscopic follow-up has been obtained in 3 patients. In all cases, the over-the-scope clip was still in place and could be removed without adverse events; recurrences were not observed. EFTR in the duodenum with the FTRD is a promising technique that has the potential to spare surgical resections. Modifications of the device should be made to facilitate introduction by mouth. Prospective studies are needed to further evaluate efficacy and safety for duodenal resections. Copyright © 2015 American Society for Gastrointestinal Endoscopy. Published by Elsevier Inc.

    Urinary function was evaluated after personal interview in 34 patients and after examination of the results of a urodynamic study in 15 of these, in whom resection for carcinoma of the rectum with preoperative irradiation therapy was performed. From the results of the personal interview, urinary urgency was found to have occurred in 19.2% when preoperative radiation was over. Urinary function after surgery was preserved in the group of patients who had undergone bilateral and unilateral pelvic plexus nerve preserving operations, whereas urinary dysfunction occurred in 66.7% of the group of patients who had undergone operations without pelvic plexus nerve preservation. Urinary dysfunction was recognized in 53.9% of the group of patients who had undergone abdominoperineal resection, but in none of the group of patients who had undergone low anterior resection. The urodynamic study showed that 21.4% had residual urinary output of more than 40 ml, 23.1% had the first desire to void at less than 100 ml, 15.4% had the maximum desire to void at less than 200 ml, 28.6% had compliance of the bladder at less than 20 ml/cmH 2 O when preoperative irradiation was over, and these data became worse 1 month after surgery. However, these phenomena were improved 1 year after surgery. (author)

    Peptide receptor radionuclide therapy is a valid therapeutic option for pancreatic neuroendocrine neoplasms. The aim of this study was to describe an initial experience with the use of peptide receptor radionuclide therapy as a neoadjuvant agent for resectable or potentially resectable pancreatic neuroendocrine neoplasms. The postoperative outcomes of 23 patients with resectable or potentially resectable pancreatic neuroendocrine neoplasms at high risk of recurrence who underwent neoadjuvant peptide receptor radionuclide therapy (peptide receptor radionuclide therapy group) were compared with 23 patients who underwent upfront surgical operation (upfront surgery group). Patients were matched for tumor size, grade, and stage. Median follow-up was 61 months. The size (median greatest width) of the primary pancreatic neuroendocrine neoplasms decreased after neoadjuvant peptide receptor radionuclide therapy (59 to 50 mm; P=.047). There were no differences in intraoperative and postoperative outcomes and there were no operative deaths, but the risk of developing a pancreatic fistula tended to be less in the peptide receptor radionuclide therapy group when compared to the upfront surgery group (0/23 vs 4/23; P radionuclide therapy group (n= 9/23 vs 17/23; P.2) differed between groups, but progression-free survival in the 31 patients who had an R0 resection seemed to be greater in the 15 patients in the peptide receptor radionuclide therapy group versus 16 patients the upfront group (median progression-free survival not reached vs 36 months; Pradionuclide therapy for resectable or potentially resectable pancreatic neuroendocrine neoplasms in patients with high-risk features of recurrence seems to be beneficial, but well-designed and much larger prospective trials are needed to confirm the safety and the oncologic value of this approach.

    Patients with advanced colorectal cancer have a high incidence of postoperative complications. We sought to identify outcomes of patients who underwent resection for colon cancer by cancer stage. The National Surgical Quality Improvement Program database was used to evaluate all patients who underwent colon resection with a diagnosis of colon cancer from 2012 to 2014. Multivariate logistic regression analysis was performed to investigate patient outcomes by cancer stage. A total of 7,786 colon cancer patients who underwent colon resection were identified. Of these, 10.8% had metastasis at the time of operation. Patients with metastatic disease had significantly increased risks of perioperative morbidity (adjusted odds ratio [AOR]: 1.44, P = .01) and mortality (AOR: 3.72, P = .01). Patients with metastatic disease were significantly younger (AOR: .99, P colon cancer have metastatic disease. Postoperative morbidity and mortality are significantly higher than in patients with localized disease. Published by Elsevier Inc.

    Laparoscopic resection for transverse colon cancer remains controversial. The aim of this study is to investigate the short- and long-term outcomes of laparoscopic surgery for transverse colon cancer. A total of 278 patients with transverse colon cancer from a single institution were included. All patients underwent curative surgery, 156 patients underwent laparoscopic resection (LR), and 122 patients underwent open resection (OR). The short- and long-term results were compared between two groups. Baseline demographic and clinical characteristics were comparable between two groups. Conversions were required in eight (5.1 %) patients. LR group was associated with significantly longer median operating time (180 vs. 140 min; P colon cancer is associated with better short-term outcomes and equivalent long-term oncologic outcomes.

    The management of rectal cancer relies on accurate MRI staging. Multi-modal treatments can downstage rectal cancer prior to surgery and may have an effect on MRI accuracy. We aim to correlate the findings of MRI staging of rectal cancer with histological analysis, the effect of neoadjuvant therapy on this and the implications of circumferential resection margin (CRM) positivity following neoadjuvant therapy. An analysis of histological data and radiological staging of all cases of rectal cancer in a single centre between 2006 and 2011 were conducted. Two hundred forty-one patients had histologically proved rectal cancer during the study period. One hundred eighty-two patients underwent resection. Median age was 66.6 years, and male to female ratio was 13:5. R1 resection rate was 11.1%. MRI assessments of the circumferential resection margin in patients without neoadjuvant radiotherapy were 93.6 and 88.1% in patients who underwent neoadjuvant radiotherapy. Eighteen patients had predicted positive margins following chemoradiotherapy, of which 38.9% had an involved CRM on histological analysis. MRI assessment of the circumferential resection margin in rectal cancer is associated with high accuracy. Neoadjuvant chemoradiotherapy has a detrimental effect on this accuracy, although accuracy remains high. In the presence of persistently predicted positive margins, complete resection remains achievable but may necessitate a more radical approach to resection.

    The postoperative results of laparoscopic distal pancreatectomy for solid pseudopapillary neoplasm of the pancreas (SPN), including the effects of spleen-preserving resection, are still to be elucidated. Of the 139 patients who underwent laparoscopic pancreatectomy for non-cancerous tumors, 14 consecutive patients (average age, 29.6 years; 1 man, 13 women) with solitary SPN who underwent laparoscopic distal pancreatectomy between March 2004 and June 2015 were enrolled. The tumors had a mean diameter of 4.8 cm. Laparoscopic spleen-preserving distal pancreatectomy was performed in eight patients (spleen-preserving group), including two cases involving pancreatic tail preservation, and laparoscopic spleno-distal pancreatectomy was performed in six patients (standard resection group). The median operating time was 317 min, and the median blood loss was 50 mL. Postoperatively, grade B pancreatic fistulas appeared in two patients (14.3%) but resolved with conservative treatment. No patients had postoperative complications, other than pancreatic fistulas, or required reoperation. The median postoperative hospital stay was 11 days, and the postoperative mortality was zero.None of the patients had positive surgical margins or lymph nodes with metastasis. The median follow-up period did not significantly differ between the two groups (20 vs 39 months, P = 0.1368). All of the patients are alive and free from recurrent tumors without major late-phase complications. Laparoscopic distal pancreatectomy might be a suitable treatment for patients with SPN. A spleen-preserving operation is preferable for younger patients with SPN, and this study demonstrated the non-inferiority of the procedure compared to spleno-distal pancreatectomy. © 2015 Japan Society for Endoscopic Surgery, Asia Endosurgery Task Force and John Wiley & Sons Australia, Ltd.

    To describe the incidence, pattern, and course of postoperative enhancement within the operative bed using serial gadolinium-enhanced magnetic resonance imaging (MRI) following vestibular schwannoma (VS) resection and to identify clinical and radiologic variables associated with recurrence. Retrospective cohort study. All patients who underwent microsurgical resection of VS between January 2000 and January 2010 at a single tertiary referral center were reviewed. Postoperative enhancement patterns were characterized on serial MRI studies. Clinical follow-up and outcomes were recorded. During the last 10 years, 350 patients underwent microsurgical VS resection, and of these, 203 patients met study criteria (mean radiologic follow-up, 3.5 years). A total of 144 patients underwent gross total resection (GTR), 32 received near-total resection (NTR), and the remaining 27 underwent subtotal resection (STR); 98.5% of patients demonstrated enhancement within the operative bed following resection (58.5% linear, 41.5% nodular). Stable enhancement patterns were seen in 24.5% of patients, regression in 66.0%, and resolution in only 3.5% of patients on the most recent postoperative MRI. Twelve patients recurred a mean of 3.0 years following surgery. The average maximum linear diameter growth rate among recurrent tumors was 2.3 mm per year. Those receiving STR were more than nine times more likely to experience recurrence compared to those undergoing NTR or GTR (P assist the clinician in determining an appropriate postoperative MRI surveillance schedule.

    We clinically investigated 34 patients with obstructive colorectal cancer who underwent placement of a colonic stent as a bridge to surgery(BTS), focusing on endoscopic findings after stent placement.Twenty -nine patients(85.3%)underwent colonoscopy after stent placement, and the entire large intestine could be observed in 28(96.6%).Coexisting lesions were observed in 22(78.6%)of these 28 patients.The lesions comprised adenomatous polyps in 17 patients(60.7%), synchronous colon cancers in 5 patients(17.9%), and obstructive colitis in 3 patients(10.7%), with some overlapping cases.All patients with multiple cancers underwent one-stage surgery, and all lesions were excised at the same time.Colonoscopy after colonic stent placement is important for preoperative diagnosis of coexisting lesions and planning the extent of resection. These considerations support the utility of colonic stenting for BTS.

    The present retrospective study compared the efficacy of wedge resection (Winograd procedure) and wedge resection plus complete nail plate avulsion for the treatment of ingrown toenails (onychocryptosis). Two surgical methods were performed in 95 patients with a stage 2 or 3 ingrown toenail. Each patient was examined weekly until healing and then at 1, 6, and 12 months of follow-up. The outcomes measured were surgical duration, healing time, recurrence rate, the incidence of postoperative infection, and cosmetic appearance after surgery. Of the 95 patients (115 ingrown toenails) included in the present study, 39 (41.1%) underwent wedge resection (Winograd procedure) and 56 (59%), wedge resection plus complete nail plate avulsion. The mean surgical duration for wedge resection (Winograd procedure) and wedge resection plus complete nail plate avulsion was 14.9 ± 2.4 minutes and 15.1 ± 3.2 minutes, respectively (p = .73). The corresponding healing times were 2.8 ± 1.2 weeks and 2.7 ± 1.3 weeks (p = .70). Recurrence developed in 3 (3.2%) patients after wedge resection (Winograd procedure) and in 4 (4.2%) after wedge resection plus complete nail plate avulsion. In addition, postoperative infection occurred in 3 (3.2%) patients after wedge resection (Winograd procedure) and 2 (2.1%) after wedge resection plus complete nail plate avulsion. Both of the surgical procedures were practical and appropriate for the treatment of ingrown toenails, being simple and associated with low morbidity and a high success rate. However, cosmetically, wedge resection (Winograd procedure) would be the better choice because the nail plate remains intact. Copyright © 2015 American College of Foot and Ankle Surgeons.

    2012-01-01

    Full Text Available Background: A prospective case series of single incision multiport laparoscopic colorectal resections for malignancy using conventional laparoscopic trocars and instruments is described. Materials and Methods: Eleven patients (seven men and four women with colonic or rectal pathology underwent single incision multiport laparoscopic colectomy/rectal resection from July till December 2010. Four trocars were placed in a single transumblical incision. The bowel was mobilized laparoscopically and vessels controlled intracorporeally with either intra or extracorporeal anastomosis. Results: Three patients had carcinoma in the caecum, one in the hepatic flexure, two in the rectosigmoid, one in the descending colon, two in the rectum and two had ulcerative pancolitis (one with high grade dysplasia and another with carcinoma rectum. There was no conversion to standard multiport laparoscopy or open surgery. The median age was 52 years (range 24-78 years. The average operating time was 130 min (range 90-210 min. The average incision length was 3.2 cm (2.5-4.0 cm. There were no postoperative complications. The average length of stay was 4.5 days (range 3-8 days. Histopathology showed adequate proximal and distal resection margins with an average lymph node yield of 25 nodes (range 16-30 nodes. Conclusion: Single incision multiport laparoscopic colorectal surgery for malignancy is feasible without extra cost or specialized ports/instrumentation. It does not compromise the oncological radicality of resection. Short-term results are encouraging. Long-term results are awaited.

    Lateral spreading tumours are superficial spreading neoplasms now increasingly diagnosed using chromoscopic colonoscopy. The clinicopathological features and safety of endoscopic mucosal resection for lateral spreading tumours (G-type "aggregate" and F-type "flat") has yet to be clarified in Western cohorts. Eighty two patients underwent magnification chromoscopic colonoscopy using the Olympus CF240Z by a single endoscopist. All patients had received a previous colonoscopy where an endoscopic diagnosis of lateral spreading tumour was made. All lesions were examined initially using indigo carmine chromoscopy to delineate contour followed by crystal violet for magnification crypt pattern analysis. A 20 MHz "mini probe" ultrasound was used if T2 disease was suspected. Following endoscopic mucosal resection, patients were followed up at 3, 6, 12, and 24 months using total colonoscopy. Eighty two lateral spreading tumours were diagnosed in 80 patients (32% (26/82) F-type and 68% (56/82) G-type). G-type lesions were larger than F-type (G-type mean 42 (SD 14) mm v F-type 24 (6.4) mm; plateral spreading tumours using endoscopic mucosal resection at two years of follow-up was 96% (56/58). Endoscopic mucosal resection for lateral spreading tumours, staged as T1, is a safe and effective treatment despite their large size. Endoscopic mucosal resection may be an alternative to surgery in selected patients.

    Objectives To present our experience of reconstructing wide defects with porously titanium mesh after radical resection of malignant chest wall tumors. Methods A retrospective review of surgical reconstruction for large chest wall resections with titanium mesh was conducted from January 2009 to August 2014 in Shanghai Chest Hospital. Results A total of 27 patients underwent major chest wall reconstructions with titanium mesh, following oncological resections. Chest wall sarcomas were the most frequent (63.0%). The mean tumor size was 72.4 (range, 36-140) cm2. The average size of the applied porously titanium mesh was 140.9 (range, 80-225) cm2. Mean postoperative length of stay was 7.1 (range, 4-14) days. There were no perioperative mortalities. Four (14.8%) patients experienced treatable complications. All had a resection of at least 3 ribs (median 3, mean 3.5 ribs). A total of 22 patients underwent ribs without sternal resections, and five patients underwent partial sternal resections with adjacent costal cartilage. Anterior chest wall resections were performed in 13 patients while lateral chest wall resections were performed in 9 patients. Three patients had extended resections beyond the chest wall in patients with primary chest wall malignancies, including two with wedge resections of lung and one with partial resection of pericardium. No patient was lost to follow-up. Mean follow-up was 30.7 months. Neither chest wall instability nor wound infection/necrosis was observed. Of these, 23 patients (85.2%) were alive at the last follow-up. Local recurrence was detected in three cases. The 5-year disease-free and overall survivals of primary chest tumors were 72.1% and 80.8%, respectively. Conclusions Our results showed that chest wall reconstruction utilizing synthetic titanium meshes following extensive resections of the chest wall malignant tumors allowed adequate resection size, with acceptable complications and survival benefits.

    Park, Sanghoon; Lee, Tae Sung

    2018-01-01

    Sagittal resection of the mandible has been widely used to reduce the width of the lower face and is usually carried out in combination with a mandibular contouring procedure. However, the surgical outcomes of this procedure are unclear because sagittal resection is rarely performed as a single procedure. The authors clarify misunderstandings regarding this procedure and introduce an improved strategic approach for sagittal resection of the mandible. Under general anesthesia, mandible contouring was performed first with a curved osteotomy, followed by sagittal resection of the outer cortex of mandible. The amount and extent of each procedure was determined in accordance with preoperative analysis. From 2012 to 2014, a consecutive series of 212 patients who underwent mandible contouring surgery without concomitant chin surgery were included in the study. A total of 189 patients underwent both mandibular contouring surgery and sagittal resection, whereas 13 underwent only sagittal resection and 10 underwent only mandibular contouring surgery. All operations were carried out successfully without any severe complications, and most patients had satisfactory aesthetic outcomes. The authors found that the sagittal resection of the mandible should be performed in accordance with the shape of the mandible to effectively reduce facial width and achieve better aesthetic outcomes for both profile and frontal views. In an outcurved-type mandible, conventional mandibular contouring may be effective alone, whereas sagittal resection focusing on removing the mandible body region is essential for incurved-type mandibles. In straight line-type mandibles, both procedures are necessary. Therapeutic, IV.

    To show the advisability, satisfactory tolerance and good analgesic effect of surgery for pancreatic ductal carcinoma with celiac trunk invasion. Distal subtotal pancreatectomy with resection of celiac trunk and common hepatic artery was made in 21 patients. Early postoperative complications after distal subtotal pancreatectomy with celiac trunk resection occurred in 10 (47.6%) patients. There was no postoperative mortality. Resection edges including retroperitoneal space and pancreas did not contain tumor cells according to histological examination. Complete analgesic effect was obtained in 100% of patients after distal subtotal pancreatectomy with celiac trunk resection and neurodissection. 1- and 2-year survival was 59.1% and 21.5% respectively in patients with locally advanced pancreatic ductal carcinoma who underwent distal subtotal pancreatectomy with celiac trunk resection, median - 13 months, maximum lifetime - 57 months. Distal subtotal pancreatectomy with resection of celiac trunk and common hepatic artery is safe, provides significant analgesic effect, increases resectability and expands the indications for pancreatectomy.

    2015-03-01

    Thymoma is best treated by surgical resection; however, no clear guidelines have been created regarding lymph node sampling at the time of resection. Additionally, the prognostic implications of nodal metastases are unclear. The aim of this study was to analyze the prognostic implications of nodal metastases in thymoma. The Surveillance, Epidemiology, and End Results database was queried for patients who underwent surgical resection of thymoma with documented pathologic examination of lymph nodes. The impact of nodal status on survival and thymoma staging was examined. We identified 442 patients who underwent thymoma resection with pathologic evaluation of 1 or more lymph nodes. A median of 2 nodes were sampled per patient. Fifty-nine patients (59 of 442, 13.3%) had ≥ 1 positive node. Patients with positive nodes were younger and had smaller tumors than node-negative patients. Median survival in the node-positive patients was 98 months, compared with 144 months in node-negative patients (P = .013). In multivariable analysis, the presence of positive nodes had a significant, independent, adverse impact on survival (hazard ratio 1.945, 95% confidence interval 1.296-2.919, P = .001). The presence of nodal metastases resulted in a change in classification to a higher stage in 80% of patients, the majority from Masaoka-Koga stage III to stage IV. Nodal status seems to be an important prognostic factor in patients with thymoma. Until the prognostic significance of nodal metastases is better understood, surgical therapy for thymoma should include sampling of regional lymph nodes.

    The key to successful rectal cancer resection is to perform complete total mesorectal excision (TME). Laparoscopic TME can be challenging, especially in the narrow confines of the pelvis. Robotic-assisted surgery can overcome these limitations through superior three-dimensional (3-D) visualization and the increased range of movements provided by the endowrist function. To date, all totally robotic resections of the rectum have been described using da Vinci® S or Si systems. Due to the limitations of the standard system, only hybrid procedures have been described so far. To evaluate the feasibility and short-term outcomes of performing totally robotic-assisted laparoscopic colorectal resections using the standard da Vinci® system with a fourth arm extension. The standard system was docked from the patient's left hip. Four 8-mm robotic trocars were inserted. Upon completion of phase 1 (pedicle ligation, colonic mobilization, splenic flexure takedown), the two left-sided arms are repositioned to allow phase 2 (pelvic dissection), enabling the entire procedure except for the distal transection and anastomosis to be performed robotically. Twenty-one robotic procedures were performed from August 2008 to September 2009. The mean age of the patients was 61 years (13 males). The procedures performed included seven anterior resections, seven low anterior resections, five ultralow anterior resections, one abdominoperineal resection, and one resection rectopexy. The majority of the cases were performed in patients with colon or rectal cancer. Operative time ranged from 232 to 444 (mean 316) min. Postoperative morbidity occurred in three patients (14.3%) with no mortalities or conversions. Average hospital stay was 6.4 days. Mean lymph node yield for the cases with cancer was 17.8. The standard da Vinci® system with four arms can be used to perform totally robotic-assisted colorectal procedures for the left colon and rectum with short-term outcomes similar to those of

    During the period from 2002 to 2011, a total of 240 consecutive patients with resectable pancreatic cancer received preoperative chemoradiation therapy (CRT). Among 240 patients, 201 patients underwent the subsequent pancreatectomy (resection rate: 84%). The 5-year overall survival of resected cases was 56% and the median survival of 39 unresected cases was 11 months. The 5-year locoregional recurrence rate of resected cases was 15%. The 5-year overall survival of the entire cohort (n=240) was 47%. The preoperative CRT and subsequent pancreatectomy provided a favorable surgical result, which was contributed by several characteristics of preoperative CRT: the prominent locoregional treatment effect with lower incidence of locoregional recurrence, and the discrimination between patients who are likely to benefit from subsequent surgery and those who are not.

    2016-01-01

    OBJECTIVE: Chest drains are used routinely after wedge resection by video-assisted thoracoscopic surgery (VATS), although this practice is based largely on tradition rather than evidence. Chest drains may furthermore cause pain, infections, and prolonged length of stay. The aim of this prospective...... observational study was to assess the feasibility of avoiding chest drains following VATS wedge resection for pulmonary nodules. METHODS: Between 1 February and 25 August 2015 166 consecutive patients planned for VATS wedge resection of pulmonary nodules were screened for inclusion using the following criteria...... effusion and coagulopathy. Chest X-rays were done twice on the day of surgery. 30-day complications were compiled from patient records. RESULTS: 49 patients underwent 51 unilateral VATS wedge resections without using a post-operative chest drain. No patient required reinsertion of a chest drain. 30 (59...

    This study examined the results of surgical treatment of 90 patients with ulcerative stenosing disease of the stomach and duodenal ulcer between 1984 and 1995. 30 patients (study group) underwent stomach Roux resection. Truncal vagotomy with stomach Bilroth-I resection (control group) was made in 20 patients, 20 patients had a truncal vagotomy with pyloroplasty according to Heineke-Mikulicz (control group), and 20 patients had a selective proximal vagotomy with gastroduodenostomy by Joboulay (control group). Motor and evacuation functions of gallbladder were assessed by dynamic US and radioisotope scintigraphy. After a Roux stomach resection and a stomach Bilroth-I resection, respectively, hypokinetic and hyperkinetic types of the gallbladder's dyskinesia was established. After a selective proximal vagotomy with gastroduodenostomy by Joboulay and truncal vagotomy with pyloroplasty according to Heineke-Mikulicz essential change of the gallbladder refractive function wasn't observed.

    The first-line treatment of encephalocele is reduction of herniated structures. Large irreducible encephalocele entails resection of the lesion. In such case, it is essential to ascertain preoperatively if the herniated structure encloses critical venous drainage. Two cases of encephalocele presenting with large occipital mass underwent magnetic resonance (MR) imaging. In first case, the skin mass enclosed the broad space containing cerebrospinal fluid and a part of occipital lobe and cerebellum. The second case had occipital mass harboring a large portion of cerebrum enclosing dilated ventricular space. Both cases had common venous anomalies such as split superior sagittal sinus and high-positioned torcular herophili. They underwent resection of encephalocele without subsequent venous congestion. We could explain the pattern of venous anomalies in encephalocele based on normal developmental theory. Developmental theory connotes that major dural sinuses cannot herniate into the sac of encephalocele. Irrespective to its size, encephalocele can be resected safely at the neck without subsequent venous congestion.

  4. Comparison of acute kidney injury between open and laparoscopic liver resection: Propensity score analysis.

    Directory of Open Access Journals (Sweden)

    Young-Jin Moon

    Full Text Available The inflammatory response has been shown to be a major contributor to acute kidney injury. Considering that laparoscopic surgery is beneficial in reducing the inflammatory response, we compared the incidence of postoperative acute kidney injury between laparoscopic liver resection and open liver resection. Among 1173 patients who underwent liver resection surgery, 222 of 926 patients who underwent open liver resection were matched with 222 of 247 patients who underwent laparoscopic liver resection, by using propensity score analysis. The incidence of postoperative acute kidney injury assessed according to the creatinine criteria of the Kidney Disease: Improving Global Outcomes definition was compared between those 1:1 matched groups. A total 77 (6.6% cases of postoperative acute kidney injury occurred. Before matching, the incidence of acute kidney injury after laparoscopic liver resection was significantly lower than that after open liver resection [1.6% (4/247 vs. 7.9% (73/926, P < 0.001]. After 1:1 matching, the incidence of postoperative acute kidney injury was still significantly lower after laparoscopic liver resection than after open liver resection [1.8% (4/222 vs. 6.3% (14/222, P = 0.008; odds ratio 0.273, 95% confidence interval 0.088-0.842, P = 0.024]. The postoperative inflammatory marker was also lower in laparoscopic liver resection than in open liver resection in matched set data (white blood cell count 12.7 ± 4.0 × 103/μL vs. 14.9 ± 3.9 × 103/μL, P < 0.001. Our findings suggest that the laparoscopic technique, by decreasing the inflammatory response, may reduce the occurrence of postoperative acute kidney injury during liver resection surgery.

    Full Text Available Purpose: This study aimed to determine the urethral stricture (US rate and identify clinical and surgical risk factors associated with US occurrence after transurethral resection of the prostate using the bipolar Gyrus PlasmaKinetic Tissue Management System (PKTURP. Materials and Methods: This was an age-matched case-control study of US occurrence after PK-TURP. Retrospective data were collected from the hospital records of patients who had a minimum of 36 months of follow-up information. Among the data collected for analysis were prostate-specific antigen level, estimated prostate weight, the amount of prostate resected, operative time, history of urinary tract infection, previous transurethral resection of the prostate, and whether the PK-TURP was combined with other endourological procedures. The resection rate was calculated from the collected data. Univariate and multivariate analyses were performed to identify clinical and surgical risk factors related to US formation. Results: A total of 373 patients underwent PK-TURP between 2003 and 2009. There were 13 cases of US (3.5%, and most of them (10 of 13, 76.9% presented within 24 months of surgery. Most of the US cases (11 of 13, 84.6% occurred at the bulbar urethra. Multivariable logistic regression analyses identified slow resection rate as the only risk factor significantly associated with US occurrence. Conclusions: The US rate of 3.5% after PK-TURP in this study is comparable to contemporary series. A slow resection rate seems to be related to US occurrence. This should be confirmed by further studies; meanwhile, we must be mindful of this possibility when operating with the PK-TURP system.

    2016-01-01

    Full Text Available Background: Resection of sacral chordomas is challenging. The anatomy is complex, and there are often no bony landmarks to guide the resection. Achieving adequate surgical margins is, therefore, difficult, and the recurrence rate is high. Use of computer navigation may allow optimal preoperative planning and improve precision in tumor resection. The purpose of this study was to evaluate the safety and feasibility of computer navigation-aided resection of sacral chordomas. Methods: Between 2007 and 2013, a total of 26 patients with sacral chordoma underwent computer navigation-aided surgery were included and followed for a minimum of 18 months. There were 21 primary cases and 5 recurrent cases, with a mean age of 55.8 years old (range: 35-84 years old. Tumors were located above the level of the S3 neural foramen in 23 patients and below the level of the S3 neural foramen in 3 patients. Three-dimensional images were reconstructed with a computed tomography-based navigation system combined with the magnetic resonance images using the navigation software. Tumors were resected via a posterior approach assisted by the computer navigation. Mean follow-up was 38.6 months (range: 18-84 months. Results: Mean operative time was 307 min. Mean intraoperative blood loss was 3065 ml. For computer navigation, the mean registration deviation during surgery was 1.7 mm. There were 18 wide resections, 4 marginal resections, and 4 intralesional resections. All patients were alive at the final follow-up, with 2 (7.7% exhibiting tumor recurrence. The other 24 patients were tumor-free. The mean Musculoskeletal Tumor Society Score was 27.3 (range: 19-30. Conclusions: Computer-assisted navigation can be safely applied to the resection of the sacral chordomas, allowing execution of preoperative plans, and achieving good oncological outcomes. Nevertheless, this needs to be accomplished by surgeons with adequate experience and skill.

    Full Text Available Pigmented villonodular synovitis (PVNS is a rare, benign, but a locally aggressive tumor. It is characterized by the proliferation of synovial membrane, but it can also be seen in tendon sheaths and bursae. Clinical presentation of solitary lesions include compression and locking of the joint suggesting loose bodies in the joint and a subsequent findings of an effusion, whereas diffuse lesions manifest with pain and chronic swelling. In this article, we presented a curious case of PVNS in a female patient who have been followed up due to an acetabular cystic lesion. She underwent total hip arthroplasty for severe osteoarthritis of the hip joint and associated pain. The diagnosis of PVNS was established intraoperatively.

To study the efficacy of cardiovascular non-invasive complex assessment and pre-operative preparation in hypertensive patients needed in surgical treatment of urology dis- eases.Material and methods. Males (n=883, aged 40 to 80 years were included into the study. The main group consisted of patients that underwent laparotomic nephrectomy (LTN group; n=96 and patients who underwent laparoscopic nephrectomy (LSN group; n=53. Dynamics of ambulatory blood pressure monitoring (ABPM data was analyzed in these groups in the immediate postoperative period. The efficacy of a package of non-invasive methods for cardiovascular system assessment was studied. ABPM was performed after nephrectomy (2-nd and 10-th days after surgery in patients with complaints of vertigo episodes or intense general weakness to correct treatment.Results. In LTN group hypotension episodes or blood pressure (BP elevations were observed in 20 (20.8% and 22 (22.9% patients, respectively, on the 2-nd day after the operation. These complications required antihypertensive treatment correction. Patients with hypotension episodes were significantly older than patients with BP elevation and had significantly lower levels of 24-hour systolic BP, night diastolic BP and minimal night systolic BP.

    Full Text Available Introduction : Gastrointestinal stromal tumours (GISTs are a rare class of neoplasms that are seen most commonly in the stomach. Due to their malignant potential, surgical resection is the recommended method for management of these tumours. Many reports have described the ability to excise small and medium sized GISTs laparoscopically, but laparoscopic resection of GISTs greater than 5 cm is still a matter of debate. Aim: To investigate the feasibility and effectiveness of laparoscopic surgical techniques for management of large gastric GISTs greater than 4 cm and to detail characteristics of this type of tumour. Material and methods: The study cohort consisted of 11 patients with suspected gastric GISTs who were treated from 2011 to April 2014 in a single institution. All patients underwent laparoscopic resection of a gastric GIST. Results : Eleven patients underwent laparoscopic resection of a suspected gastric GIST between April 2011 and April 2014. The cohort consisted of 6 males and 5 females. Mean age was 67 years (range: 43–92 years. Sixty-four percent of these patients presented with symptomatic tumours. Four (36.4% patients underwent laparoscopic transgastric resection (LTR, 3 (27.3% laparoscopic sleeve gastrectomy (LSG, 3 (27.3% laparoscopic wedge resection (LWR and 1 (9% laparoscopic distal gastrectomy (LDG. The mean operative time was 215 min. The mean tumour size was 6 cm (range: 4–9 cm. The mean tumour size for LTR was 5.5 cm (range: 4–6.3 cm, for LWR 5.3 cm (range: 4.5–7 cm, for LSG 6.5 cm (range: 4–9 cm and for LDG 9 cm. We experienced only minor postoperative complications. Conclusions : Laparoscopic procedures can be successfully performed during management of large gastric GISTs, bigger than 4 cm, and should be considered for all non-metastatic cases. The appropriate approach can be determined by assessing the anatomical location of each tumour.

    Full Text Available ObjectiveTo compare clinical efficacy and recurrence between surgical resection and radiofrequency ablation (RFA in the treatment of small hepatocellular carcinoma (HCC. MethodsThe clinical data of 97 patients with small HCC, who underwent surgical resection or RFA as the initial treatment in The First Hospital of Jilin University from January 2002 to December 2008, were collected. Sixty-three cases, who survived 2 years after treatment, were followed up; of the 63 cases, 34 underwent surgical resection, and 29 underwent RFA. The recurrence of these patients was analyzed retrospectively. The measurement data were analyzed by chi-square test. The Cox regression analysis was used for determining the risk factors for recurrence. The log-rank test was used for disease-free survival (DFS difference analysis. ResultsThe 3-month, 1-year, and 2-year intrahepatic recurrence rates for the patients who underwent surgical resection were 15%, 38%, and 64%, respectively, versus 21%, 35%, and 45% for those who underwent RFA, without significant differences between the two groups of patients. The intrahepatic recurrence after initial treatment was not significantly associated with treatment method, sex, age, Child-Pugh grade, tumor size, number of nodules, presence of cirrhosis, and alpha-fetoprotein level. There was no significant difference in DFS between the two groups of patients. ConclusionRFA produces a comparable outcome to that by surgical resection in the treatment of small HCC. RFA holds promise as a substitute for surgical resection.

    Most submucosal tumors (SMTs) in the esophagogastric junction (EGJ) are irregularly shaped and different from those in the esophagus, where submucosal tunneling endoscopic resection (STER) has been proven effective and safe. However, few reports paid attention to STER for SMTs in the EGJ. The aim of the study was not only to evaluate the effect of STER in patients with SMTs in the EGJ but to analyze the risk factors for failure of en bloc resection. A consecutive of 47 patients with SMTs originating from the muscularis propria (MP) layer in the EGJ underwent STER were retrospectively included between September 2012 and December 2016. Thirty-five tumors underwent en bloc resection, and the other 12 tumors received piecemeal resection. The tumor size, operation time, en bloc resection rate, complications, residual, and local recurrence were achieved and compared between the two groups. Forty-six of 47 lesions (97.9%) were successfully resected. The mean lesion size was 29.7 ± 16.3 mm. Both the en bloc resection rate and complete resection rate were 74.5% (35/47). No severe complications occurred in the 47 patients. Patients in the piecemeal resection group had more irregularly shaped lesions, longer tumor diameter, larger tumor size (≥40 mm), longer operation time, and longer hospital stay after procedure (P  0.05). By univariate analysis and stepwise logistic regression analysis, irregular shape and tumor diameter ≥20 mm were two risk factors for failure of en bloc resection. STER is an effective and safe technique for the treatment of SMTs arising from the MP layer in the EGJ. Irregular shape and tumor diameter ≥20 mm are the reliable risk factors for en bloc resection failure.

    Prophylactic abdominal drainage is performed routinely after liver resection in many centers. The aim of this study was to examine the safety and validity of liver resection without abdominal drainage and to clarify whether routine abdominal drainage after liver resection is necessary. Patients who underwent elective liver resection without bilio-enteric anastomosis between July, 2006 and June, 2012 were divided into two groups, based on whether surgery was performed before or after, we adopted the no-drain strategy. The "former group" comprised 256 patients operated on between July, 2006 and June, 2009 and the "latter group" comprised 218 patients operated between July, 2009 and June, 2012. We compared the postoperative complications, percutaneous drainage, and postoperative hospital stay between the groups, retrospectively. There were no significant differences in the rates of postoperative bleeding, intraabdominal infection, or bile leakage between the groups. Drain insertion after liver resection did not reduce the rate of percutaneous drainage. Postoperative hospital stay was significantly shorter in the latter group. Routine abdominal drainage is unnecessary after liver resection without bilio-enteric anastomosis.

    There is limited veterinary literature about dogs or cats with ileocolic junction resection and its long-term follow-up. To evaluate the long-term outcome in a cohort of dogs and cats that underwent resection of the ileocolic junction without extensive (≥50%) small or large bowel resection. Medical records of dogs and cats that had the ileocolic junction resected were reviewed. Follow-up information was obtained either by telephone interview or e-mail correspondence with the referring veterinary surgeons. Nine dogs and nine cats were included. The most common cause of ileocolic junction resection was intussusception in dogs (5/9) and neoplasia in cats (6/9). Two dogs with ileocolic junction lymphoma died postoperatively. Only 2 of 15 animals, for which long-term follow-up information was available, had soft stools. However, three dogs with suspected chronic enteropathy required long-term treatment with hypoallergenic diets alone or in combination with medical treatment to avoid the development of diarrhoea. Four of 6 cats with ileocolic junction neoplasia were euthanised as a consequence of progressive disease. Dogs and cats undergoing ileocolic junction resection and surviving the perioperative period may have a good long-term outcome with mild or absent clinical signs but long-term medical management may be required.

    Background  About one-third of rhabdomyosarcomas arise in the head and neck, with parameningeal primaries accounting for half of these. Principles of management involve chemotherapy, radiation, or both, in addition to surgical biopsy, debulking, and complete or near-complete resection. In the head and neck, diagnostic biopsies have historically been performed without attempt at resection due to proximity to critical structures and cosmetic considerations. Methods  Retrospective chart review of three cases of rhabdomyosarcoma at the cranial base managed through minimally invasive endoscopic surgical resection and adjuvant therapy. Results  Three patients were identified as having undergone endoscopic surgical debulking or margin-negative resection of a rhabdomyosarcoma of the cranial base. Two of three patients had complete resection based on intraoperative margin control. All three patients underwent adjuvant therapy within 1 month of diagnosis. Follow-up time ranged from 5 months to 3 years with all patients disease-free at last follow-up. Conclusion  Skull base surgeons should routinely be involved in multidisciplinary treatment planning for parameningeal rhabdomyosarcomas, as surgical options have evolved to allow for potential endoscopic resection with low morbidity and no or minimal delay in additional treatment options.

    This study was performed to evaluate short-term clinical outcomes of laparoscopic intracorporeal ileocolic anastomosis following resection of the right colon. This was a retrospective study of selected patients who underwent laparoscopic intracorporeal ileocolic anastomosis following resection of the right colon for tumors or Crohn's disease by a single surgeon from July 2002 through June 2012. Data were retrieved from an Institutional Review Board-approved database. Study end point was postoperative adverse events, including mortality, complications, reoperations, and readmissions at 30 days. Antiperistaltic side-to-side anastomoses were fashioned laparoscopically with a 60-mm-long stapler cartridge and enterocolotomy was hand-sewn intracorporeally in two layers. Values were expressed as medians (ranges) for continuous variables. There were 243 patients (143 females) aged 61 (range = 19-96) years, with body mass index of 29 (18-43) kg/m(2) and ASA 1:2:3:4 of 52:110:77:4; 30 % had previous abdominal surgery and 38 % had a preexisting comorbidity. There were 84 ileocolic resections with ileo ascending anastomosis and 159 right colectomies with ileotransverse anastomosis. Operating time was 135 (60-220) min. Estimated blood loss was 50 (10-600) ml. Specimen extraction site incision length was 4.1 (3-4.4) cm. Conversion rate was 3 % and there was no mortality at 30 days, 15 complications (6.2 %), and 8 reoperations (3.3 %). Readmission rate was 8.7 %. Length of stay was 4 (2-32) days. Pathology confirmed Crohn's disease in 84 patients, adenocarcinoma in 152, and other tumors in 7 patients. Laparoscopic intracorporeal ileocolic anastomosis following resection of the right colon resulted in a favorable outcome in selected patients with Crohn's disease or tumors of the right colon.

    Reinsertion of the distal common bile duct (CBD) into the pancreatic resection cavity during duodenum-preserving pancreatic head excision (DPPHE) may be an alternative option to Whipple resection or bilioenteric anastomosis when chronic pancreatitis is associated with CBD stenosis. Outcome in 82 patients with chronic pancreatitis who underwent DPPHE with CBD reinsertion was compared with that in 432 who had DPPHE without reinsertion and 50 who had a Whipple procedure or pylorus-preserving pancreatoduodenectomy (PPPD). There were no deaths after DPPHE with CBD reinsertion, compared with four (0.9 per cent) after DPPHE without reinsertion and three (6 per cent) after classical resection. Overall morbidity rates were 30, 28.9 and 36 per cent respectively. Fifteen patients (18 per cent) who had DPPHE with CBD reinsertion developed a stricture at the reinsertion site, compared with a long-term stricture rate of 2.3 per cent (ten patients) after DPPHE without CBD reinsertion and 4 per cent (two patients) after PPPD/Whipple resection. Although associated with a high incidence of anastomotic stricture, reinsertion of the CBD into the resection cavity as part of DPPHE can be used to preserve duodenal passage and offers an alternative to extended resection for chronic pancreatitis. 2007 British Journal of Surgery Society Ltd.

    Endoscopic full-thickness resection of gastric subepithelial tumors with a full-thickness suturing device has been described as feasible in two small case series. The aim of this study was to evaluate the efficacy, safety, and clinical outcome of this resection technique. After 31 patients underwent endoscopic full-thickness resection, the data were analyzed retrospectively. Before snare resection, 1 to 3 full-thickness sutures were placed underneath each tumor with a device originally designed for endoscopic anti-reflux therapy. All tumors were resected successfully. Bleeding occurred in 12 patients (38.7 %); endoscopic hemostasis could be achieved in all cases. Perforation occurred in 3 patients (9.6 %), and all perforations could be managed endoscopically. Complete resection was histologically confirmed in 28 of 31 patients (90.3 %). Mean follow-up was 213 days (range, 1 - 1737), and no tumor recurrences were observed. Endoscopic full-thickness resection of gastric subepithelial tumors with the suturing technique described above is feasible and effective. After the resection of gastrointestinal stromal tumors (GISTs), we did not observe any recurrences during follow-up, indicating that endoscopic full-thickness resection may be an alternative to surgical resection for selected patients. © Georg Thieme Verlag KG Stuttgart · New York.

    We recently identified metastatic prostate carcinoma (PCA) within perirectal lymph nodes (PLNs) from 2 patients undergoing abdominoperineal resection (APR) for rectal adenocarcinoma (RA). As this phenomenon has not been addressed by any studies in the literature and because these positive PLNs had the potential to be mistakenly diagnosed as metastatic RA, we were prompted to undertake a retrospective study of rectal resections for RA to determine the frequency of PCA metastasizing to the PLNs in this patient population. The laboratory information system of the Department of Pathology, Capital Health, Halifax, Nova Scotia was searched for lymph node (LN)-positive RAs resected by low anterior resection or APR in male patients between January 1, 1992 and December 31, 2002. The hematoxylin and eosin slides were retrieved and reviewed, comparing the histology of the primary rectal tumor with that of the LN metastases in each case. Metastases having a different histologic appearance than the primary rectal tumor or having a pattern suggestive of metastatic PCA were analyzed by immunohistochemistry to detect prostate specific antigen (PSA), prostatic acid phosphatase (PAP), cytokeratin 7 (CK7), cytokeratin 20 (CK20), and carcinoembryonic antigen in LN metastases and in each RA. The presence or absence of mucin in the tumors was assessed by staining with Alcian blue, periodic acid-Schiff (PAS) +/- diastase, and modified PANFOPAS (2-hydroxy-3-naphthoic acid hydrazide/fast black B/saponification/periodic acid-Schiff). The study identified 112 cases of RA with positive LNs. Of those, 5 of 112 (4.5%) were identified as having metastatic PCA within the PLNs. All five were positive for PSA and PAP and only one case had rare CK20-positive tumor cells. The primary RAs were all diffusely positive for CK20 and carcinoembryonic antigen. Two cases of metastatic PCA expressed colonic type/acetylsialomucin, which was also seen in well-differentiated primary RAs. These 5 patients had a

    The role of integrated (18)F-2-fluoro-2-deoxy-D-glucose positron emission tomography computed tomography (PET-CT) is uncertain in gallbladder cancer. The aim of this study was to show the role of PET-CT in gallbladder cancer patients. Fifty-three patients with gallbladder cancer underwent preoperative computed tomography (CT) and PET-CT scans. Their medical records were retrospectively reviewed. Twenty-six patients underwent resection. Based on the final outcomes, PET-CT was in good agreement (0.61 to 0.80) with resectability whereas CT was in acceptable agreement (0.41 to 0.60) with resectability. When the diagnostic accuracy of the predictions for resectability was calculated with the ROC curve, the accuracy of PET-CT was higher than that of CT in patients who underwent surgical resection (P=0.03), however, there was no difference with all patients (P=0.12). CT and PET-CT had a discrepancy in assessing curative resection in nine patients. These consisted of two false negative and four false positive CT results (11.3%) and three false negative PET-CT results (5.1%). PET-CT was in good agreement with the final outcomes compared to CT. As a complementary role of PEC-CT to CT, PET-CT tended to show better prediction about resectability than CT, especially due to unexpected distant metastasis.

    2001-01-01

    Purpose: To assess the toxicity and the efficacy of preoperative radiotherapy with continuous infusion 5-fluorouracil (5-FU) for locally advanced adenocarcinoma of the rectum. Methods and Materials: Eligible patients had newly diagnosed localized adenocarcinoma of the rectum within 12 cm of the anal verge, Stage T3-4, and were suitable for curative resection. Eighty-two patients were treated with radiotherapy--50.4 Gy in 28 fractions in 5.6 weeks, given concurrently with continuous infusion 5-FU, using either 96-h/week infusion at 300 mg/m 2 /day or 7-days/week infusion at 225 mg/m 2 /day. Results: The median age was 59 years (range, 27-87), and 67% of patients were male. Pretreatment stages of the rectal cancer were T3, 89% and resectable T4, 11%, with endorectal ultrasound confirmation in 67% of patients. Grade 3 acute toxicity occurred in 5 of 82 patients (6%; 95% confidence interval [CI], 2-14%). Types of surgical resection were anterior resection, 61%; abdominoperineal resection, 35%; and other procedures, 4%. There was no operative mortality. Anastomotic leakage after low anterior resection occurred in 3 of 50 patients (6%; 95% CI, 1-17%). The pathologic complete response rate was 16% (95% CI, 9-26%). Pathologic Stages T2 or less occurred in 51%. Conclusion: Preoperative radiotherapy with continuous infusion 5-FU for locally advanced rectal cancer is a safe regimen, with a significant downstaging effect. It does not seem to lead to a significant increase in serious surgical complications

    Conventional endoscopic resection techniques such as endoscopic mucosal resection (EMR) or endoscopic submucosal dissection (ESD) are powerful tools for the treatment of gastrointestinal (GI) neoplasms. However, those techniques are limited to the superficial layers of the GI wall (mucosa and submucosa). Lesions without lifting sign (usually arising from deeper layers) or lesions in difficult anatomic positions (appendix, diverticulum) are difficult - if not impossible - to resect using conventional techniques, due to the increased risk of complications. For larger lesions (>2 cm), ESD appears to be superior to the conventional techniques because of the en bloc resection, but the procedure is technically challenging, time consuming, and associated with complications even in experienced hands. Since the development of the over-the-scope clips (OTSC), complications like bleeding or perforation can be endoscopically better managed. In recent years, different endoscopic full-thickness resection techniques came to the focus of interventional endoscopy. Since September 2014, the full-thickness resection device (FTRD) has the CE marking in Europe for full-thickness resection in the lower GI tract. Technically the device is based on the OTSC system and combines OTSC application and snare polypectomy in one step. This study shows all full-thickness resection techniques currently available, but clearly focuses on the experience with the FTRD in the lower GI tract.

    To determine the accuracy of preoperative MR imaging for evaluation of resectability of extrahepatic bile duct carcinoma. Thirty-four patients with proven extrahepatic bile duct carcinoma underwent pre-operative MR imaging. All MR examinations were performed with a 1.5T system, using a phased-array multicoil. Tumor resectability was prospectively determined by two radiologists who reached consensus. Ten patients did not undergo surgery because the preoperative MR imaging, CT and endoscopic findings all indicated unresectability. Twenty-five patients subsequently underwent surgical exploration, and their imaging and pathologic and laparotomic findings were compared. Twenty-two of 34 cases (65%) were resectable. Among the 22 cases resectable in laparotomy, pre-operative MR imaging had suggested that 20 were resectable, and sensitivity for resectability was thus 91%. Among the 22 cases in which MR imaging had suggested resectability, macroscopic clearance was complete in 20, giving a positive value of 91%. MR imaging underestimated portal venous or hepatic arterial invasion, and in one case missed small (<1cm) hepatic metastases. In two cases, MR imaging overestimated portal venous or hepatic arterial encasement. MR imaging is a useful diagnostic modality for preoperative assessment of resectability of extrahepatic bile duct cancer.=20.

    2014-12-16

    Management of subepithelial tumors (SETs) remains challenging. Endoscopic ultrasound (EUS) has improved differential diagnosis of these tumors but a definitive diagnosis on EUS findings alone can be achieved in the minority of cases. Complete endoscopic resection may provide a reasonable approach for tissue acquisition and may also be therapeutic in case of malignant lesions. Small SET restricted to the submucosa can be removed with established basic resection techniques. However, resection of SET arising from deeper layers of the gastrointestinal wall requires advanced endoscopic methods and harbours the risk of perforation. Innovative techniques such as submucosal tunneling and full thickness resection have expanded the frontiers of endoscopic therapy in the past years. This review will give an overview about endoscopic resection techniques of SET with a focus on novel methods.

    Full Text Available Introduction: Hypersplenism is a common complication of portal hypertension. Cytopenia in hypersplenism is predominantly caused by splenomegaly. Distal splenorenal shunt (Warren with partial spleen resection is an original surgical technique that regulates cytopenia by reduction of the enlarged spleen. Objective. The aim of our study was to present the advantages of distal splenorenal shunt (Warren with partial spleen resection comparing morbidity and mortality in a group of patients treated by distal splenorenal shunt with partial spleen resection with a group of patients treated only by a distal splenorenal shunt. Method. From 1995 to 2003, 41 patients with portal hypertension were surgically treated due to hypersplenism and oesophageal varices. The first group consisted of 20 patients (11 male, mean age 42.3 years who were treated by distal splenorenal shunt with partial spleen resection. The second group consisted of 21 patients (13 male, mean age 49.4 years that were treated by distal splenorenal shunt only. All patients underwent endoscopy and assessment of oesophageal varices. The size of the spleen was evaluated by ultrasound, CT or by scintigraphy. Angiography was performed in all patients. The platelet and white blood cell count and haemoglobin level were registered. Postoperatively, we noted blood transfusion, complications and total hospital stay. Follow-up period was 12 months, with first checkup after one month. Results In the first group, only one patient had splenomegaly postoperatively (5%, while in the second group there were 13 patients with splenomegaly (68%. Before surgery, the mean platelet count in the first group was 51.6±18.3x109/l, to 118.6±25.4x109/l postoperatively. The mean platelet count in the second group was 67.6±22.8x109/l, to 87.8±32.1x109/l postoperatively. Concerning postoperative splenomegaly, statistically significant difference was noted between the first and the second group (p<0.05. Comparing the

    After 20 years of experience in laparoscopic liver surgery there is still no clear definition of the best approach (totally laparoscopic [TLS] or hand-assisted [HAS]), the indications for surgery, position, instrumentation, immediate and long-term postoperative results, etc. To report our experience in laparoscopic liver resections (LLRs). Over a period of 10 years we performed 132 LLRs in 129 patients: 112 malignant tumours (90 hepatic metastases; 22 primary malignant tumours) and 20 benign lesions (18 benign tumours; 2 hydatid cysts). Twenty-eight cases received TLS and 104 had HAS. 6 right hepatectomies (2 as the second stage of a two-stage liver resection); 6 left hepatectomies; 9 resections of 3 segments; 42 resections of 2 segments; 64 resections of one segment; and 5 cases of local resections. There was no perioperative mortality, and morbidity was 3%. With TLS the resection was completed in 23/28 cases, whereas with HAS it was completed in all 104 cases. Transfusion: 4,5%; operating time: 150min; and mean length of stay: 3,5 days. The 1-, 3- and 5-year survival rates for the primary malignant tumours were 100, 86 and 62%, and for colorectal metastases 92, 82 and 52%, respectively. LLR via both TLS and HAS in selected cases are similar to the results of open surgery (similar 5-year morbidity, mortality and survival rates) but with the advantages of minimally invasive surgery.

    A growing number of operations for sigmoid diverticulitis are being done laparoscopically. There is a paucity of data on the outcome of laparoscopy for sigmoid diverticulitis complicated by colonic fistula. The aim of this study was to compare the results of laparoscopic resection of sigmoid diverticulitis with and without colonic fistula. A retrospective review was conducted of all patients who underwent laparoscopic resection of sigmoid diverticulitis complicated by fistula at a single tertiary care institution over a 7-year period. Comparison was made with a group of patients who underwent resection for diverticulitis without fistula during the same study period. Forty-two patients were analyzed (group 1: diverticular fistula, group 2: no fistula). The median age was similar (49 vs. 50 years, P = .68). A chronic abscess was present in 24% of patients in group 1 and 10% in group 2 (P = .40). Fistula types were colovesical (71%), colovaginal (19%), and colocutaneous (10%). Operation types were sigmoidectomy (57% vs. 81%) and anterior resection (43% vs. 19%) in groups 1 and 2, respectively (P = .18). Ureteral catheters were used more frequently in group 1 (67% vs. 33% [P = .06]). No difference was noted in operative time, blood loss, conversion rate, length of stay, overall complications, wound infection rate, readmission rate, reoperation rate, and mortality. All patients healed without fistula recurrence. Patients with sigmoid diverticulitis with fistula can be successfully treated with laparoscopic excision, with similar outcomes for patients without fistula.

    The role of perioperative chemotherapy in the management of initially resectable colorectal liver metastases (CRLM) is still unclear. The EPOC trial [the European Organization for Research and Treatment of Cancer (EORTC) 40983] is an important study that declares perioperative chemotherapy as the standard of care for patients with resectable CRLM, and the strategy is widely accepted in western countries. Compared with surgery alone, perioperative FOLFOX therapy significantly increased progression-free survival (PFS) in eligible patients or those with resected CRLM. Overall survival (OS) data from the EPOC trial were recently published in The Lancet Oncology, 2013. Here, we discussed the findings and recommendations from the EORTC 40983 trial. PMID:25713806

    Video thoracoscopic sympathectomy is the recommended surgical treatment for primary hyperhidrosis and has a high success rate. Despite this high success rate, some patients are unresponsive and eventually need a resympathectomy. Few studies have previously analysed exclusively the results of these resympathectomies in patients with primary hyperhidrosis. None of the studies have objectively evaluated the degree of response to surgery or the improvement in quality of life after resympathectomies. This is a retrospective study, evaluating 15 patients from an initial group of 2300 patients who underwent resympathectomy after failure of the primary surgical treatment. We evaluated sympathectomy levels of resection, technical difficulties, surgical complications preoperative quality of life, response to treatment and quality-of-life improvement 30 days after each surgery. Regarding gender, 11 (73.3%) patients were women. The average age was 23.2 with SD of 5.17 years, and the mean body mass index was 20.9 (SD 2.12). Ten patients had major complaints about their hands (66%) and 5 (33%) patients about their forearms. A high degree of response to sympathectomy occurred in 73% of patients. In 11 of these patients, the improvement in quality of life was considered high, 3 showed a mild improvement and 1 did not improve. No major complications occurred; the presence of adhesions was reported in 11 patients and pleural drainage was necessary in 4 patients. Resympathectomy is an effective procedure, and it improves the quality of life in patients with primary hyperhidrosis who failed after the first surgery. © The Author 2017.

    Available are the results of surgical treatment of 90 patients with stenotic gastroduodenal ulcer in Burdenko Surgical Faculty Hospital of Sechenov Moscow Medical Academy between 1984 and 1985. 30 patients (study group) underwent stomach Roux-type resection. Truncal vagotomy with a stomach Bilroth-I resection was made in 20 control patients, after 20 control patients had a truncal vagotomy with pyloroplasty according to Heineke-Mikulicz, and 20 patients had selective proximal vagotomy with gastroduodenostomy by Joboulay (the third control group). Exocrine function of the pancreas was assessed by serum concentration of immunoreactive trypsin, endocrine function by fasting blood sugar, oral glucose tolerance and serum concentration of immunoreactive insulin. The authors came to the conclusion that exocrine function of the pancreas was equally damaged in patients with a Roux stomach resection, stem vagotomy with a stomach Bilroth-I resection and a stem vagotomy with pyloroplasty Heineke-Mikulicz. After selective proximal vagotomy a level of immunoreactive trypsin was normal. After a Roux stomach resection relative incompetence of basophil cells of the pancreas and long increase of insulin in the blood were observed but without influence on the glucose curve. The changes of glucose curve and level of immunoreactive insulin were similar in the control groups.

    OBJECTIVE Recent studies have demonstrated that periventricular tumor location is associated with poorer survival and that tumor location near the ventricle limits the extent of resection. This finding may relate to the perception that ventricular entry leads to further complications and thus surgeons may choose to perform less aggressive resection in these areas. However, there is little support for this view in the literature. This study seeks to determine whether ventricular entry is associated with more complications during craniotomy for brain tumor resection. METHODS A retrospective analysis of patients who underwent craniotomy for tumor resection at Henry Ford Hospital between January 2010 and November 2012 was conducted. A total of 183 cases were reviewed with attention to operative entry into the ventricular system, postoperative use of an external ventricular drain (EVD), subdural hematoma, hydrocephalus, and symptomatic intraventricular hemorrhage (IVH). RESULTS Patients in whom the ventricles were entered had significantly higher rates of any complication (46% vs 21%). Complications included development of subdural hygroma, subdural hematoma, intraventricular hemorrhage, subgaleal collection, wound infection, urinary tract infection/deep venous thrombosis, hydrocephalus, and ventriculoperitoneal (VP) shunt placement. Specifically, these patients had significantly higher rates of EVD placement (23% vs 1%, p entry (11% vs 0%, p = 0.001) with 3 of 4 of these patients having a large ventricular entry (defined here as entry greater than a pinhole [entry). Furthermore, in a subset of glioblastoma patients with and without ventricular entry, Kaplan-Meier estimates for survival demonstrated a median survival time of 329 days for ventricular entry compared with 522 days for patients with no ventricular entry (HR 1.13, 95% CI 0.65-1.96; p = 0.67). CONCLUSIONS There are more complications associated with ventricular entry during brain tumor resection than in

    Full Text Available Aim. To study genes regulating the extracellular matrix (ECM and investigate the tissue remodelling following liver resection in porcine. Methods. Four pigs with 60% partial hepatectomy- (PHx- induced liver regeneration were studied over six weeks. Four pigs underwent sham surgery and another four pigs were used as controls of the normal liver growth. Liver biopsies were taken upon laparotomy, after three and six weeks. Gene expression profiles were obtained using porcine-specific oligonucleotide microarrays. Immunohistochemical staining was performed and a proliferative index was assessed. Results. More differentially expressed genes were associated with the regulation of ECM in the resection group compared to the sham and control groups. Secreted protein acidic and rich in cysteine (SPARC and collagen 1, alpha 2 (COL1A2 were both upregulated in the early phase of liver regeneration, validated by immunopositive cells during the remodelling phase of liver regeneration. A broadened connective tissue was demonstrated by Masson’s Trichrome staining, and an immunohistochemical staining against pan-Cytokeratin (pan-CK demonstrated a distinct pattern of migrating cells, followed by proliferating cell nuclear antigen (PCNA positive nuclei. Conclusions. The present study demonstrates both a distinct pattern of PCNA positive nuclei and a deposition of ECM proteins in the remodelling phase of liver regeneration.

    Deep organ space infection (DOSI) is a serious complication after emergency bowel resection and anastomosis. The aim of this study was to identify the incidence and risk factors for the development of DOSI. National Surgical Quality Improvement Program database study including patients who underwent large bowel or small bowel resection and primary anastomosis. The incidence, outcomes, and risk factors for DOSI were evaluated using univariate and multivariate analyses. A total of 87,562 patients underwent small bowel, large bowel, or rectal resection and anastomosis. Of these, 14,942 (17.1%) underwent emergency operations and formed the study population. The overall mortality rate in emergency operations was 12.5%, and the rate of DOSI was 5.6%. A total of 18.0% required ventilatory support in more than 48 hours, and 16.0% required reoperation. Predictors of DOSI included age, steroid use, sepsis or septic shock on admission, severe wound contamination, and advanced American Society of Anesthesiologists classification. The anatomic location of resection and anastomosis was not significantly associated with DOSI. Patients undergoing emergency bowel resection and anastomosis have a high mortality, risk of DOSI, and systemic complications. Independent predictors of DOSI include wound and American Society of Anesthesiologists classification, sepsis or septic shock on admission, and steroid use. The anatomic location of resection and anastomosis was not significantly associated with DOSI. Epidemiologic/prognostic study, level III.

    BACKGROUND Adrenocortical carcinoma (ACC) is an aggressive malignancy typically resistant to chemotherapy and radiation. Surgery, even in the setting of locally recurrent or metastatic disease, remains the only potentially curative option. However, the subset of patients who will benefit from repeat resection in this setting remains ill defined. The objective of this study was to propose a prognostic clinical score that facilitates selection of patients for repeat resection of recurrent ACC. STUDY DESIGN Patients who underwent curative-intent repeat resection for recurrent ACC at 1 of 13 academic medical centers participating in the US ACC Study Group were identified. End points included morbidity, mortality, and overall survival. RESULTS Fifty-six patients underwent repeat curative-intent resection for recurrent ACC (representing 21% of 265 patients who underwent resection for primary ACC) from 1997 to 2014. Median age was 52 years. Sites of resected recurrence included locoregional only (54%), lung only (14%), liver only (12%), combined locoregional and lung (4%), combined liver and lung (4%), and other distant sites (12%). Thirty-day morbidity and mortality rates were 40% and 5.4%, respectively. Cox regression analysis revealed that the presence of multifocal recurrence, disease-free interval 12 months, and locoregional or pulmonary recurrence. PMID:27618748

    Delayed gastric emptying is one of the most frequent postoperative complications after Whipple resection. In the present study we evaluated the role of enteral nutrition in the development of delayed gastric emptying after Whipple resection. Between January 1996 and June 1998, 64 patients (30 female, 34 male) underwent a classic (n = 27) or pylorus-preserving (n = 37) Whipple resection. Two patients were excluded; 30 patients received enteral and 32 patients received no-enteral nutrition. Delayed gastric emptying occurred significantly more in patients with enteral (17 of 30, 57%) than in patients with no-enteral nutrition (5 of 32, 16%) (P nasogastric tube for a significantly (Pindications.

    The aim of this study was to determine the optimal laparoscopic approach for wedge resection of gastric submucosal tumors (SMTs) based on tumor characteristics. Between March 2008 and June 2010, 57 patients underwent laparoscopic wedge resection for suspected gastric SMT. Of these 57 patients, 40 underwent exogastric wedge resection (EWR), with the remaining undergoing transgastric wedge resection (TWR). Fifty-seven consecutive patients undergoing surgical resection of gastric SMT were reviewed, with 40 and 17 tumors treated with EWR and TWR, respectively. The average tumor size was significantly greater in the EWR group (p = 0.004). A circular tumor location was a decisive factor for selecting the laparoscopic approach (p = 0.011). Tumors presenting with exophytic growths were predominantly found in the EWR group, and those with endophytic growth were dominant in the TWR group (p pattern.

    Sarcoma is the most common midface malignancy in children. While first-line treatment in adults is resection, the challenges associated with resection and reconstruction of these tumors in children often lead to radiation therapy as primary treatment. This report highlights the feasibility and efficacy of midface reconstruction in the pediatric population after resection. In most cases, the same principles utilized in reconstructing midface defects in adults hold for the pediatric population. From 2008 to 2013 seven pediatric patients underwent resection and reconstruction for maxillary sarcomas. These patients ranged in age from 18 months to 20 years. Five patients were reconstructed with six microvascular free flaps. Two patients received pedicled flaps. Follow-up ranged from 15 months to 4.5 years. Reconstructive, oncological, and functional outcomes were analyzed. Seven patients underwent eight reconstructions for sarcomas of the maxilla. Flaps utilized included vertical rectus abdominis, anterolateral thigh, fibula, and temporoparietal fascia. One flap was complicated by venous thrombosis but was successfully salvaged after thrombectomy and revision using vein graft. One patient developed recurrence after initial flap placement and required salvage resection and a second free flap. Six patients were judged to have good facial symmetry and tolerated a regular oral diet with normal or near-normal dental occlusion. Standard primary therapy for sarcomas of the maxilla in the pediatric population consists of nonsurgical management. However, a radiation-first approach is associated with significant morbidity and makes surgical salvage more difficult. Based on our experience, microsurgical reconstruction of the pediatric midface is safe and effective, and should be considered a first-line treatment option for midface sarcomas in children. In general, there is no significant area of departure between the principles that govern midface reconstruction in adults and

    The most serious complication of acute mesenteric vein thrombosis (MVT) is acute intestinal ischaemia requiring intestinal resection or causing death. Risk factors for this complication are unknown. To identify risk factors for severe intestinal ischaemia leading to intestinal resection in patients with acute MVT. We retrospectively analysed consecutive patients seen between 2002 and 2012 with acute MVT in 2 specialized units. Patients with cirrhosis were excluded. We compared patients who required intestinal resection to patients who did not. Among 57 patients, a local risk factor was identified in 14 (24%) patients, oral contraceptive use in 16 (29%), and at least one or more other systemic prothrombotic condition in 25 (44%). Five (9%) patients had diabetes mellitus (DM), 33 (58%) had overweight or obesity, 9 (18%) had hypertriglyceridemia and 10 (19%) had arterial hypertension. Eleven patients (19%) underwent intestinal resection. DM was significantly associated with intestinal resection (P = 0.02) while local factors or prothrombotic conditions were not. Computed tomography (CT) scans performed at diagnosis found that occlusion of second order radicles of the superior mesenteric vein was more frequently observed in patients who underwent intestinal resection (P = 0.009). In acute MVT, patients with underlying DM have an increased risk of requiring intestinal resection. Neither local factors nor systemic prothrombotic conditions are associated with intestinal resection. When CT scan shows the preservation of second order radicles of the superior mesenteric vein, the risk of severe resection is low. © 2013 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    The objective of this work was to report success rates as well as potential obstacles in transnasal endoscopic resection of anterior skull base meningiomas. The study design was a case series with chart review at tertiary referral centers in South Australia and New Zealand. The patients were 37 consecutive patients who underwent endoscopic resection of skull-base meningiomas between 2004 and 2013. Review of patient charts and operative details were performed. Outcomes including complications are reported. Eighty-four percent of patients were women. There were 28 primary and 9 revision cases. Tumor locations were as follows: 14 olfactory groove/subfrontal; 12 planum/jugum sphenoidale; 7 tuberculum sellae; 3 clinoidal; and 1 clival. Vision change was the most common presenting symptom. Mean tumor volume was 33.68 cm(3) , mean diameter was 2.78 cm. Average operating times decreased with an initial learning curve and then plateaued. Primary tumors larger than 60 cm(3) took an average of 10 hours to resect. Gross total removal was achieved in 29 patients. There were no perioperative deaths. Two deaths occurred within 1 year of surgery. Postoperative cerebrospinal fluid (CSF) leaks occurred in 13 patients. Seventy-five percent of patients presenting with visual loss reported visual improvement. Of the 29 patients considered to have had complete resection at surgery, one was found to have residual disease on a postoperative magnetic resonance imaging (MRI) and another one later developed radiological evidence of recurrence. Using a 2-team approach, meningiomas of the skull base were successfully removed via an intranasal endoscopic technique. Although complete resection is typically possible even with large tumors, the lengthy resection required time for tumors larger than 60 cm(3) (diameter ≥4 cm) may obviate some of the advantages of this approach. The rate of postoperative CSF leak decreases when a synthetic dural substitute is added but does not approach zero.

    The first-line treatment for resectable pancreatic cancer (RPC) is surgical resection. However, our patients have often experienced early recurrence after curative resection for RPC, with desperately poor prognosis. Some reports indicated that minimally distant metastasis not detected at operation might cause early recurrence. The present study aimed to identify preoperative clinicopathological features of early recurrence after curative resection of RPC. Ninety RPC patients who underwent curative resection between 2000 and 2014 at our institution were retrospectively analyzed. Of the 90 patients, 32 had recurrence within 1 year. Univariate analysis demonstrated that preoperative serum carbohydrate antigen (CA19-9) ≥529 U/mL (P = 0.0011), preoperative serum s-pancreas-1 antigen (SPan-1) ≥37 U/mL (P = 0.0038), and histological grades G2-G4 (P = 0.0158) were significantly associated with recurrence within 1 year after curative resection. Multivariate analysis demonstrated that preoperative serum CA19-9 ≥ 529 U/mL (P = 0.0477) and histological grade G2-G4 (P = 0.0129) were independent predictors of recurrence within 1 year. Recurrent cases within 1 year postoperatively had significantly more distant metastasis than cases with no recurrence within 1 year (P Preoperative serum CA19-9 ≥ 529 U/mL and histological grades G2-G4 were independent predictive factors for recurrence within 1 year after pancreatectomy for RPC. Furthermore, recurrent cases within 1 year had more frequent distant metastasis than cases with no recurrence within 1 year. These results suggest that RPC patients with preoperative serum CA19-9 ≥ 529 U/mL should receive preoperative therapy rather than surgery.

    The optimal strategy for pleural dissemination of advanced thymoma remains controversial, while a potential benefit from macroscopic clearance of disseminations has been reported. In this study, we review our mid-term results of surgical resection of pleural disseminations of invasive thymoma. Data from patients with pleural dissemination synchronously or metachronously to primary invasive thymoma who underwent surgical resection from 1991 to 2012 at our institute were retrospectively reviewed. Of 136 thymoma patients who underwent surgery during the study period, 13 consecutive patients with pleural dissemination (synchronous: 7, metachronous: 6) with a median age of 49 years (range: 27-78 years) at the time of dissemination resection were identified. No patients presented with haematogenous metastases. Operative procedures included the thorough resection of visible disseminated nodules in 11 patients and extrapleural pneumonectomy (EPP) in 2 patients. The median number of resected nodules was 6 (range: 1-52). The median follow-up was 948 days (range: 38-4025 days). One patient died of postoperative bleeding, but there were no tumour-related deaths during the study period. Pleural recurrence was found in 9 cases, including 2 EPP cases, and among them, 3 underwent repeated resection. The overall survival and the recurrence-free survival ratio at 5 years was 92.3 and 33.3%, respectively. Five patients, including 2 repeated resection cases, remained tumour-free at the final observation. Resection of pleural dissemination of invasive thymoma can be performed in selected patients and may offer optimal local control as part of a multimodal strategy. © The Author 2014.

    We report a case of an intractable fistula repaired by transsacral direct suture. A 65-year-old man underwent low anterior resection for rectal cancer. He subsequently underwent ileostomy due to anastomosis leakage. The fistula of the anastomosis persisted 3 months after surgery. He underwent surgery to repair the fistula using a transsacral approach. After removing the coccyx, the fistula in the postrectal space was exposed directly. The presence of the fistula was confirmed by an air leak test and was closed by direct suture. After 33 days, the patient underwent ileostomy closure.

    In esophageal cancer, circumferential resection margins (CRMs) are considered to be of relevant prognostic value, but a reliable definition of tumor-free CRM is still unclear. The aim of this study was to appraise the clinical prognostic value of microscopic CRM involvement and to determine the optimal limit of CRM. To define the optimal tumor-free CRM we included 98 consecutive patients who underwent extended esophagectomy with microscopic tumor-free resection margins (R0) between 1997 and 2006. CRMs were measured in tenths of millimeters with inked lateral margins. Outcome of patients with CRM involvement was compared with a statistically comparable control group of 21 patients with microscopic positive resection margins (R1). A cutoff point of CRM at 1.0 mm appeared to be an adequate marker for survival and prognosis (both P 0 mm was equal to that in patients with CRM of 0 mm (P = 0.43). CRM involvement was an independent prognostic factor for both recurrent disease (P = 0.001) and survival (P CRM is CRM is >1.0 mm. Patients with unfavorable CRM should be approached as patients with R1 resection with corresponding outcome.

    Full Text Available Background. It is unclear if the availability of new techniques for removal of large colonic polyps has affected the use of segmental colon resection. We sought to evaluate the characteristics of polyps undergoing surgical resection, including involvement of therapeutic gastroenterologists (TG. Methods. 484 patients had a colonic resection; 165 (34% were identified from the pathology database with polyp, adenoma, or mass in the clinical history field; these charts were reviewed. Results. 128 patients (mean age 68 yrs, 72% male were included. The mean polyp size was 2.9 cm (0.4 cm–12.0 cm. Adenocarcinoma was diagnosed in 50 (39.1%. 97 (75.8% patients had a polyp that was felt to be unresectable by EMR, and 31 (24.2% underwent successful EMR followed by surgery for adenocarcinoma (n=29. The indication for surgery in those with unresectable polyps was variable and was not clearly documented in 51 (52.6%; only 17 of these patients (17.5% had a TG involved. Conclusion. A high proportion of polyps managed by segmental resection did not contain adenocarcinoma. This data suggests that even in a tertiary care center where advanced endoscopic techniques are easily available, they are not always utilized. Educational endeavors to ensure that ideal pathways of intervention are utilized require implementation.

    Postoperative neurologic outcomes after primary somatosensory cortex (S1) resection have not been well documented. This study was designed to evaluate the neurologic deterioration that follows resection of the S1 areas and to assess the risk factors associated with these morbidities. We reviewed 48 consecutive patients with medically intractable epilepsy who underwent resection of the S1 and/or the adjacent cortex. The 48 patients were categorized into 4 groups according to the resected area as seen on postoperative magnetic resonance images: group 1 (resection of S1 only; n = 4), 2 (the posterior parietal cortex [PPC] only; n = 24), 3 (S1 and PPC; n = 10), and 4 (S1 and precentral gyrus; n = 10). After the resection of S1 areas, 19 patients (40%) experienced neurologic worsening, including 6 (13%) with permanent and 13 (27%) with transient deficits. Patients with permanent deficits included 2 with motor dysphasia, 1 with dysesthesia, 2 with equilibrium impairments, and 1 with fine movement disturbance of the hand. The overall and permanent neurologic risks were 25% and 0% in group 1, 17% and 4% in group 2, 80% and 20% in group 3, and 60% and 30% in group 4, respectively. Multivariate analysis determined that the resection of both S1 and PPC was the only significant risk factor for neurologic deficits (P = 0.002). The neurologic risk of the resection of S1 and/or its adjacent cortical areas was 40%. The additional resection of the PPC was significantly associated with the development of postoperative neurologic impairments. Copyright © 2017 Elsevier Inc. All rights reserved.

    Purpose: To evaluate, in a phase 2 study, the safety and efficacy of induction gemcitabine, oxaliplatin, and cetuximab followed by selective capecitabine-based chemoradiation in patients with borderline resectable or unresectable locally advanced pancreatic cancer (BRPC or LAPC, respectively). Methods and Materials: Patients received gemcitabine and oxaliplatin chemotherapy repeated every 14 days for 6 cycles, combined with weekly cetuximab. Patients were then restaged; “downstaged” patients with resectable disease underwent attempted resection. Remaining patients were treated with chemoradiation consisting of intensity modulated radiation therapy (54 Gy) and concurrent capecitabine; patients with borderline resectable disease or better at restaging underwent attempted resection. Results: A total of 39 patients were enrolled, of whom 37 were evaluable. Protocol treatment was generally well tolerated. Median follow-up for all patients was 11.9 months. Overall, 29.7% of patients underwent R0 surgical resection (69.2% of patients with BRPC; 8.3% of patients with LAPC). Overall 6-month progression-free survival (PFS) was 62%, and median PFS was 10.4 months. Median overall survival (OS) was 11.8 months. In patients with LAPC, median OS was 9.3 months; in patients with BRPC, median OS was 24.1 months. In the group of patients who underwent R0 resection (all of which were R0 resections), median survival had not yet been reached at the time of analysis. Conclusions: This regimen was well tolerated in patients with BRPC or LAPC, and almost one-third of patients underwent R0 resection. Although OS for the entire cohort was comparable to that in historical controls, PFS and OS in patients with BRPC and/or who underwent R0 resection was markedly improved

    Thymoma is an uncommon tumor without a widely accepted standard care to date. We aimed to investigate the clinicopathologic variables of patients with thymoma and identify possible predictors of survival and recurrence after initial resection. We retrospectively selected 307 patients with thymoma who underwent complete resection at the Cancer Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College (Beijing, China) between January 2003 and December 2014. The associations of patients' clinical characteristics with prognosis were estimated using Cox regression and Kaplan-Meier survival analyses. During follow-up (median, 86 months; range, 24-160 months), the 5- and 10-year disease-free survival (DFS) rates were 84.0% and 73.0%, respectively, and the 5- and 10-year overall survival (OS) rates were 91.0% and 74.0%, respectively. Masaoka stage (P thymoma who underwent repeated resection had increased post-recurrence survival rates compared with those who underwent therapies other than surgery (P = 0.017). Masaoka stage and WHO histological classification were independent prognostic factors of thymoma after initial complete resection. The recurrence pattern was an independent predictor of post-recurrence survival. Locoregional recurrence and repeated resection of the recurrent tumor were associated with favorable prognosis.

    Full Text Available Upper cervical chordoma (UCC is rare condition and poses unique challenges to surgeons. Even though transoral approach is commonly employed, a minimally invasive technique has not been established. We report a 44-year old Malay lady who presented with a 1 month history of insidious onset of progressive neck pain without neurological symptoms. She was diagnosed to have an axial (C2 chordoma. Intralesional resection of the tumour was performed transorally using the Destandau endoscopic system (Storz, Germany. Satisfactory intralesional excision of the tumour was achieved. She had a posterior fixation of C1-C4 prior to that. Her symptoms improved postoperatively and there were no complications noted. She underwent adjuvant radiotherapy to minimize local recurrence. Endoscopic excision of UCC via the transoral approach is a safe option as it provides an excellent magnified view and ease of resection while minimizing the operative morbidity.

    In this report, the feasibility, efficacy and safety of laparoscopic liver resection with radiofrequency has been evaluated in a small series of patients. From January 1993 to May 2002 we carried out 7 laparoscopic liver resections (3 men and 4 women), five of which were for benign pathology and two for metastases from colorectal cancer. In four of the above resections we used an argon coagulator; the last three were accomplished by means of a radiofrequency instrument. We had no perioperative or postoperative complications in this small series of patients. There were no deaths. Perioperative blood loss was of 120 mL (range 80-200) and the procedure took about 90 minutes (range 80-110). Hospitalization was of 4 days and pain was adequately controlled by 2 mL of Toradol twice a day. We think that the advantages of laparoscopic techniques together with the efficacy of the radiofrequency instrument in hepatic surgery will allow the diffusion of this method and its extension to safe execution of major resections.

    Full Text Available Surgical treatment of brain tumors, especially those located in the eloquent areas such as anterior temporal, frontal lobes, language, memory areas, and near the motor cortex causes high risk of eloquent impairment. Awake craniotomy displays major rule for maximum resection of the tumor with minimum functional impairment of the Central Nervous System. These case reports discuss the use of awake craniotomy during the brain surgery in Alzahra Hospital, Isfahan, Iran. A 56-year-old woman with left-sided body hypoesthesia since last 3 months and a 25-year-old with severe headache of 1 month duration were operated under craniotomy for brain tumors resection. An awake craniotomy was planned to allow maximum tumor intraoperative testing for resection and neurologic morbidity avoidance. The method of anesthesia should offer sufficient analgesia, hemodynamic stability, sedation, respiratory function, and also awake and cooperative patient for different neurological test. Airway management is the most important part of anesthesia during awake craniotomy. Tumor surgery with awake craniotomy is a safe technique that allows maximal resection of lesions in close relationship to eloquent cortex and has a low risk of neurological deficit.

    In order to improve the surgical treatment of rectal cancer, robot-assisted laparoscopy has been introduced. The robot has gained widespread use; however, the scientific basis for treatment of rectal cancer is still unclear. The aim of this study was to investigate whether robot-assisted laparoscopic rectal resection cause less perioperative pain than standard laparoscopic resection measured by the numerical rating scale (NRS score) as well as morphine consumption. Fifty-one patients were randomized to either laparoscopic or robot-assisted rectal resection at the Department of Surgery at Aarhus University Hospital in Denmark. The intra-operative analgetic consumption was recorded prospectively and registered in patient records. Likewise all postoperative medicine administration including analgesia was recorded prospectively at the hospital medical charts. All morphine analogues were converted into equivalent oral morphine by a converter. Postoperative pain where measured by numeric rating scale (NRS) every hour at the postoperative care unit and three times a day at the ward. Opioid consumption during operation was significantly lower during robotic-assisted surgery than during laparoscopic surgery (p=0.0001). However, there were no differences in opioid consumption or NRS in the period of recovery. We found no differences in length of surgery between the two groups; however, ten patients from the laparoscopic group underwent conversion to open surgery compared to one from the robotic group (p=0.005). No significant difference between groups with respect to complications where found. In the present study, we found that patients who underwent rectal cancer resection by robotic technique needed less analgetics during surgery than patients operated laparoscopically. We did, however, not find any difference in postoperative pain score or morphine consumption postoperatively between the robotic and laparoscopic group.

    Full Text Available PURPOSE: To report the risk of catecholamine crisis in patients undergoing resection of unsuspected pheochromocytoma. MATERIALS AND METHODS: Over a four-year period, we retrospectively identified four patients who underwent resection of adrenal pheochromocytoma in whom the diagnosis was unsuspected based on preoperative clinical, biochemical, and imaging evaluation. RESULTS: None of the patients exhibited preoperative clinical features of catecholamine excess. Preoperative biochemical screening in two patients was normal. CT scan performed in all patients demonstrated a nonspecific enhancing adrenal mass. During surgical resection of the adrenal mass, hemodynamic instability was observed in two of four patients, and one of these two patients also suffered a myocardial infarct. CONCLUSION: Both surgeons and radiologists should maintain a high index of suspicion for pheochromocytoma, as the tumor can be asymptomatic, biochemically negative, and have nonspecific imaging features. Resection of such unsuspected pheochromocytomas carries a substantial risk of intraoperative hemodynamic instability.

    The recent improvements in chemotherapy and surgical resection in Ewing sarcoma (ES) increased the overall survival as well as the importance of chest wall reconstruction. These improvements are in order to avoid asymmetrical growth, functional and cosmetic compromise after surgery. Chest wall reconstruction still remains a big issue in young patients with ES. We present a case of ES of the left chest wall, arising from a rib, in a 14-year-old patient. He was admitted after neoadjuvant chemotherapy and radiotherapy. The patient underwent a chest wall resection of three ribs and a wedge lung resection of the upper lobe followed by chest wall reconstruction with Stratos™ rib titanium prostheses. This new device is suitable for reconstruction after major chest wall resection with good cosmetic and functional results. During the follow-up, there was no evidence of local and distant recurrence, the pain was under control and there were no functional alterations in the chest wall.

    We report a rare case of spermatic cord metastasis from colon cancer. A man in his 50s underwent extended right hemicolectomy for transverse colon cancer followed by resection of a peritoneal recurrence. After receiving adjuvant chemotherapy for 6 months, he became aware of a right inguinal mass. A spermatic cord tumor was noted on computed tomography(CT) and FDG/PET-CT. He underwent radical orchiectomy. The resected tumor was histologically compatible with the colon cancer. Although he received additional chemotherapy, right inguinal recurrence was resected 6 months after orchiectomy. Colon cancer is the second most common origin, after gastric cancer, of metastatic spermatic tumor. As several metastatic routes have been reported, peritoneal seeding is mostly suspected in this case.

    Purpose We evaluated the prognostic value of 18F-2-fluoro-2-deoxyglucose positron emission tomography (FDG PET) in patients with resectable pancreatic cancer. Materials and Methods We retrospectively reviewed the medical records of pancreatic cancer patients who underwent curative resection, which included 64 consecutive patients who had preoperative FDG PET scans. For statistical analysis, the maximal standardized uptake value (SUVmax) of primary pancreatic cancer was measured. Survival time was estimated by the Kaplan-Meier method, and Cox's proportional hazard model was used to determine whether SUVmax added new predictive information concerning survival together with known prognostic factors. p3.5) showed significantly shorter OS and DFS than the low SUVmax group. Multivariate analysis of OS and DFS showed that both high SUVmax and poor tumor differentiation were independent poor prognostic factors. Conclusion Our study showed that degree of FDG uptake was an independent prognostic factor in pancreatic cancer patients who underwent curative resection. PMID:24142641

    Full Text Available AIM: To observe the change of lens antioxidant enzyme activity after glaucoma trabecular resection. METHODS: Thirty-two eyes of sixteen New-Zealand rabbits(2.2-2.4kgwere divided into two groups. The left eyes of rabbits underwent standard glaucoma trabecular resection were treatment group, and the normal right eyes served as controls. Transparency of lenses was monitored by a slit-lamp biomicroscopy before and after glaucoma trabecular resection. The morphology of lens cells was observed under the light microscope.The activities of Na+-K+-ATPase,catalase(CAT, glutathion peroxidase(GSH-px, glutathione reductase(GR, superoxide dismutase(SODand content of malondialdehyde(MDAin lenses were detected six months after trabecular resection. RESULTS: Lenses were clear in both treatment group and normal control group during the six months after operation. The morphology and structure of lens cells were normal under the light microscope in both operation group and normal group. The activity of lens cells antioxidant enzyme activity were significantly decreased in operation group compared with control group, Na+-K+-ATPase declined by 20.97%, CAT declined by 16.36%, SOD declined by 4.46%, GR declined by 4.85%, GSH-px declined by 10.02%, and MDA increased by 16.31%. CONCLUSION: Glaucoma trabecular resection can induce the change of Na+-K+-ATPase, CAT, GSH-px, GR, SOD and MDA in lens of rabbit. Glaucoma filtration surgery for the occurrence of cataract development mechanism has important guiding significance.

    Full Text Available For colorectal cancer patients, long-term survival is achievable only after complete resection of the disease. However, the decision to embark on a multi-visceral resection must be made after weighing the risks against the potential benefits. We retrospectively analyzed the demographics, tumor parameters, perioperative results, oncological outcomes and survival details of 35 patients who underwent multivisceral resection for colorectal carcinoma between 1996 and 2013. 'Multivisceral resection' was defined as the resection of at least one other organ in addition to cancer affected the colon. There were 19 males and 16 females who had a mean age of 52.7 ± 13.6 years. The most common primary site of the tumor was the rectum, followed by the sigmoid, the left, and the right colon. Most frequently resected additional organ was the pancreas followed by the uterus, small bowel, urinary bladder, ureter, vagina, spleen, duodenum, ovary, and liver. Postoperative histopathological examination confirmed tumor infiltration in the adjacent organs in 48.5%. The postoperative complication was developed in 21 (60% patients. There was no surgery-related mortality. Ten patients had evidence of recurrence at last follow-up in June 2014. The 5-year survival rate was of 73.1% according to Kaplan-Meier survival analysis. Multivisceral resection for colorectal cancer is associated with a high morbidity rate, but the long-term survival is good.

    To describe the characteristics of patients with colorectal endometriosis and extraserosal pelvic fascia (EPF) involvement and to assess the effect of EPF resection. Prospective cohort study (Canadian Task Force classification II-2). University hospital. Two hundred twenty-seven patients who underwent segmental colorectal resection to treat symptomatic deep infiltrating endometriosis between 2001 and 2011, with or without EPF resection. Segmental colorectal resection with or without EPF resection. One hundred twelve patients (49.4%) required EPF resection. In these patients the total American Society for Reproductive Medicine endometriosis scores were higher (p = .004), there were more associated resected lesions of deep infiltrating endometriosis (p <.001), and the operative time was longer (p <.001). They were more likely to require blood transfusion (p = .003) and to experience intraoperative complications (p = .01) and postoperative voiding dysfunction (p = .04). EPF infiltration reflects disease severity in patients with colorectal endometriosis. Its removal affects intraoperative morbidity and leads to a higher rate of voiding dysfunction.

    Objective  To determine the volume of ventral skull base tumor removed following endoscopic endonasal (EEA) resection using MRI-based volumetric analysis and to evaluate the inter-rater reliability of such analysis. Design  Retrospective case series. Setting  Academic tertiary care hospital. Participants  EEA patients November 2012 to August 2015. Main Outcome Measures  Volumetric analysis of pre- and immediately postoperative MR imaging was performed independently by two investigators. The percentage of total tumor resected was evaluated according to resection goal and tumor type. Results  A total of 39 patients underwent resection. Intraclass correlation coefficients between the raters were 0.9988 for preoperative and 0.9819 for postoperative images. Tumors (and average percentage removed) included 17 nonsecreting pituitary adenomas (95.3%), 8 secreting pituitary adenomas (86.2%), 4 meningiomas (81.6%), 3 olfactory neuroblastomas (100%), 2 craniopharyngiomas (100%), 1 large B-cell lymphoma (90.5%), 1 germ cell neoplasm (48.3), 1 benign fibrous connective tissue mass (93.4%), 1 epidermoid cyst (68.4%), and 1 chordoma (100%). For tumors treated with intent for gross total resection, 96.9 ± 4.8% was removed. Conclusion  EEAs achieved tumor resection rates of ∼97% when total resection was attempted. The radiographic finding of residual tumor is of uncertain clinical significance. The volumetric analysis employed in this study demonstrated high inter-rater reliability and could facilitate further study.

  10. Computational fluid dynamics as surgical planning tool: a pilot study on middle turbinate resection.

    Controversies exist regarding the resection or preservation of the middle turbinate (MT) during functional endoscopic sinus surgery. Any MT resection will perturb nasal airflow and may affect the mucociliary dynamics of the osteomeatal complex. Neither rhinometry nor computed tomography (CT) can adequately quantify nasal airflow pattern changes following surgery. This study explores the feasibility of assessing changes in nasal airflow dynamics following partial MT resection using computational fluid dynamics (CFD) techniques. We retrospectively converted the pre- and postoperative CT scans of a patient who underwent isolated partial MT concha bullosa resection into anatomically accurate three-dimensional numerical nasal models. Pre- and postsurgery nasal airflow simulations showed that the partial MT resection resulted in a shift of regional airflow towards the area of MT removal with a resultant decreased airflow velocity, decreased wall shear stress and increased local air pressure. However, the resection did not strongly affect the overall nasal airflow patterns, flow distributions in other areas of the nose, nor the odorant uptake rate to the olfactory cleft mucosa. Moreover, CFD predicted the patient's failure to perceive an improvement in his unilateral nasal obstruction following surgery. Accordingly, CFD techniques can be used to predict changes in nasal airflow dynamics following partial MT resection. However, the functional implications of this analysis await further clinical studies. Nevertheless, such techniques may potentially provide a quantitative evaluation of surgical effectiveness and may prove useful in preoperatively modeling the effects of surgical interventions. © 2014 Wiley Periodicals, Inc.

  11. The impact of pulmonary metastasectomy in patients with previously resected colorectal cancer liver metastases.

    Armin Wiegering

    Full Text Available 40-50% of patients with colorectal cancer (CRC will develop liver metastases (CRLM during the course of the disease. One third of these patients will additionally develop pulmonary metastases.137 consecutive patients with CRLM, were analyzed regarding survival data, clinical, histological data and treatment. Results were stratified according to the occurrence of pulmonary metastases and metastases resection.39% of all patients with liver resection due to CRLM developed additional lung metastases. 44% of these patients underwent subsequent pulmonary resection. Patients undergoing pulmonary metastasectomy showed a significantly better five-year survival compared to patients not qualified for curative resection (5-year survival 71.2% vs. 28.0%; p = 0.001. Interestingly, the 5-year survival of these patients was even superior to all patients with CRLM, who did not develop pulmonary metastases (77.5% vs. 63.5%; p = 0.015. Patients, whose pulmonary metastases were not resected, were more likely to redevelop liver metastases (50.0% vs 78.6%; p = 0.034. However, the rate of distant metastases did not differ between both groups (54.5 vs.53.6; p = 0.945.The occurrence of colorectal lung metastases after curative liver resection does not impact patient survival if pulmonary metastasectomy is feasible. Those patients clearly benefit from repeated resections of the liver and the lung metastases.

    Objectives We evaluated the accuracy of augmented reality (AR)-based navigation assistance through simulation of bone tumours in a pig femur model. Methods We developed an AR-based navigation system for bone tumour resection, which could be used on a tablet PC. To simulate a bone tumour in the pig femur, a cortical window was made in the diaphysis and bone cement was inserted. A total of 133 pig femurs were used and tumour resection was simulated with AR-assisted resection (164 resection in 82 femurs, half by an orthropaedic oncology expert and half by an orthopaedic resident) and resection with the conventional method (82 resection in 41 femurs). In the conventional group, resection was performed after measuring the distance from the edge of the condyle to the expected resection margin with a ruler as per routine clinical practice. Results The mean error of 164 resections in 82 femurs in the AR group was 1.71 mm (0 to 6). The mean error of 82 resections in 41 femurs in the conventional resection group was 2.64 mm (0 to 11) (p Augmented reality in bone tumour resection: An experimental study.

    Arguments against biliary drainage before pancreatoduodenectomy have been gaining momentum recently. The benefits of biliary drainage before hepatobiliary resection, ie, combined liver and extrahepatic bile duct resection, however, are still debatable. To review the outcomes of patients who underwent hepatobiliary resection, with special attention to preoperative biliary drainage, to investigate whether biliary drainage increases the risk of postoperative infectious complications. This study involved 587 patients who underwent hepatobiliary resection with cholangiojejunostomy, including 475 patients who underwent preoperative biliary drainage and 112 patients who did not. Before each operation, surveillance bile cultures were performed at least once a week. Postoperatively, the bile and drainage fluid were cultured on days 1, 4, and 7. The hospital records of consecutive patients who underwent hepatobiliary resection were reviewed retrospectively. Of the 475 patients with biliary drainage, 356 (74.9%) had a positive bile culture during the preoperative period. The incidence of postoperative infectious complications, including surgical-site infection and bacteremia, was similar between patients with biliary drainage and those without (28.2% vs 28.6%, P = .939). A positive bile culture during the perioperative period was highly associated with infectious complications and was one of the independent predictive factors related to infectious complications in a multivariate analysis. Preoperative biliary drainage is unlikely to increase the incidence of infectious complications after hepatobiliary resection. Perioperative surveillance bile culture is useful for the perioperative selection of appropriate antibiotics because of the high likelihood that micro-organisms isolated from infected sites are identical to those isolated from bile.

Our study was designed to assess whether AGR is associated with the prognosis of gastric cancer patients. Patients and methods: A total of 507 gastric cancer patients between 2005 and 2012 were included. The AGR was defined as the ratio of serum albumin to nonalbumin and calculated by the equation: albumin/(total protein - albumin. Furthermore, AGR was divided into two groups (low and high using the X-tile software. Survival analysis stratified by AGR groups was performed. Results: The mean survival time for each group was 36.62 months (95% CI: 33.92–39.32 for the low AGR group and 48.95 months (95% CI: 41.93–55.96, P=0.003 for the high AGR group. Patients in the high group (AGR ≥1.93 had a significantly lower 5-year mortality in comparison with the low group (AGR <1.93 (52.4% vs 78.5%, P=0.003. The high AGR group showed obviously better overall survival than the low AGR group according to Kaplan–Meier curves (P=0.003. Multivariate analysis showed that AGR was an independent predictive factor of prognosis in gastric patients. Conclusion: Pretreatment AGR is a significant and independent predictive factor of prognosis. Keywords: gastric cancer, survival, inflammation, albumin–globulin ratio

    Although robot-assisted pancreatic surgery has been considered critically in the past, it is nowadays an established standard technique in some centers, for distal pancreatectomy and pancreatic head resection. Compared with the laparoscopic approach, the use of robot-assisted surgery seems to be advantageous for acquiring the skills for pancreatic, bile duct and vascular anastomoses during pancreatic head resection and total pancreatectomy. On the other hand, the use of the robot is associated with increased costs and only highly effective and professional robotic programs in centers for pancreatic surgery will achieve top surgical and oncological quality, acceptable operation times and a reduction in duration of hospital stay. Moreover, new technologies, such as intraoperative fluorescence guidance and augmented reality will define additional indications for robot-assisted pancreatic surgery.

    ERAS is a multimodal perioperative care program which replaces traditional practices concerning analgesia, intravenous fluids, nutrition, mobilization as well as a number of other perioperative items, whose implementation is supported by evidence-based best practices. According to the RICA guidelines published in 2015, a review of the literature and the consensus established at a multidisciplinary meeting in 2015, we present a protocol that contains the basic procedures of an ERAS pathway for resective esophageal surgery. The measures involved in this ERAS pathway are structured into 3areas: preoperative, perioperative and postoperative. The consensus document integrates all the analyzed items in a unique time chart. ERAS programs in esophageal resection surgery can reduce postoperative morbidity, mortality, hospitalization and hospital costs. Copyright © 2018 AEC. Publicado por Elsevier España, S.L.U.

One trial included participants with Hinchey I characteristics as well as those who underwent Hartmann's procedure; the second trial included only participants with "a proven stage II/III disease according to the classification of Stock and Hansen"; the third trial considered for inclusion patients with "diverticular disease of sigmoid colon documented by colonoscopy and 2 episodes of uncomplicated diverticulitis, one at least being documented with CT scan, 1 episode of complicated diverticulitis, with a pericolic abscess (Hinchey stage I) or pelvic abscess (Hinchey stage II) requiring percutaneous drainage."We determined that two studies were at low risk of selection bias; two that reported considerable dropouts were at high risk of attrition bias; none reported blinding of outcome assessors (unclear detection bias); and all were exposed to performance bias owing to the nature of the intervention.Available low-quality evidence suggests that laparoscopic surgical resection may lead to little or no difference in mean hospital stay compared with open surgical resection (3 studies, 360 participants; MD -0.62 (days), 95% CI -2.49 to 1.25; I² = 0%).Low-quality evidence suggests that operating time was longer in the laparoscopic surgery group than in the open surgery group (3 studies, 360 participants; MD 49.28 (minutes), 95% CI 40.64 to 57.93; I² = 0%).We are uncertain whether laparoscopic surgery improves postoperative pain between day 1 and day 3 more effectively than open surgery. Low-quality evidence suggests that laparoscopic surgery may improve postoperative pain at the fourth postoperative day more effectively than open surgery (2 studies, 250 participants; MD = -0.65, 95% CI -1.04 to -0.25).Researchers reported quality of life differently across trials, hindering the possibility of meta-analysis.

    Full-thickness chest wall resection is the well-established treatment for primary or metastatic chest wall tumors. Adequate surgery with large resections is always needed to achieve a radical resection in healthy tissues, leading to optimal local control of the disease. The purpose of this study is to present our experience in chest wall reconstruction after major tumor resection. Patients and Methods: Between January 2006 and January 2010, 18 consecutive patients who underwent major chest wall resections for primary or metastatic chest wall tumors were studied. All had resection of at least three ribs and immediate reconstruction. Surgical procedures, extent of the resection, resulting defects and postoperative morbidity and mortality were discussed. Results: Surgical indications included primary, recurrent and metastatic chest wall neoplasms, sarcoma and recurrent breast cancer were the most frequent diagnoses. Resection of 3 ribs was performed in 8 patients, while resection of more than 3 ribs was performed in 10 patients. Resection of sternum and adjacent costal cartilages was performed in one patient, right chest wall resections were performed in 7 patients while left chest wall resections were performed in 10 patients. Immediate repair of the defects was performed in all cases, all patient had placement of prosthesis either polypropylene or polytetrafluoroethylene, 3 patients had methylacrylate in addition to the prosthesis. Coverage w as achieved using myocutaneous flaps in 7 patients. Mechanical ventilation was needed in 11 patients with a mean duration of ventilation 2.211.8 days (range between 1- 6 days). No 30-days mortality was recorded. Four patients 22.2% developed complications, 2 patients need prolonged mechanical ventilation for respiratory insufficiency and 2 patients had partial flap necrosis and wound infection. Mean hospital stay was 10.1±3.2 days. Conclusion: Immediate reconstruction of large full thickness chest wall defects following

    Objective: To compare the effectiveness, safety and morbidity of strictureplasty with resection anastomosis in patients with tuberculous small gut strictures. Subjects and Methods: Thirty patients who presented with intestinal obstruction due to tuberculous strictures, and underwent either resection anastomosis or strictureplasty where included in the study. Data was collected on a proforma and analyzed using software SPSS (version 8.0). Chi-square and t-test were used to test the hypothesis. Main outcome measures included the presence or absence of postoperative leakage anastomosis, wound infection, recurrence of intestinal obstruction and postoperative study. Results: Chi-square test applied to see the effectiveness showed no significant difference (p>0.5) between the two procedures. t-Test on the score of morbidity also showed no significant difference (p>0.5) between the two procedures. Conclusion: Both procedures performed were equally effective and had equal morbidity in cases of intestinal tuberculous strictures. Strictureplasty is superior to resection anastomosis in cases of multiple strictures as it conserves gut length and can even be performed safely in cases with coexistent gut perforation. (author)

    To study the clinically diagnosed disease process but also identify additional, clinically undetected pathologies in femoral heads resected for replacement arthroplasty. A retrospective review was carried out of the pathological findings in 460 surgically resected femoral heads. Serial sections were submitted to low-energy fine-detail radiography, then decalcified sections stained by the WHO method were examined. The preoperative clinical and imaging diagnoses were compared with the pathological findings and special interest was placed on assessing the clinical significance of any unexpected, clinically undetected findings. The most common findings included the presence of bone islands (solitary osteomas) and areas of avascular necrosis in addition to the primary joint disease for which the patient underwent surgery. The preoperative symptomatology did not distinguish between the known primary disease and the additional pathological findings. Some of the clinically unidentified lesions were of a size that fell below the ability of current clinical investigations to detect. However, the finding of lesions by tissue fine-detail radiography indicates that current, more sensitive clinical imaging techniques may identify them. Careful examination of surgically resected femoral heads is important to ensure that all pathologies are identified and assessed for clinical relevance. (orig.)

    The inclusion criteria were established for a videothoracoscopic resection of early-stage thymoma. We retrospectively evaluated the validity of these criteria in the treatment of early-stage thymoma. The computed tomography (CT) image characteristics and clinical information comprised these criteria. The image considerations included the location of the tumor in the anterior mediastinum, a distinct fat plane between the tumor and vital organs, unilateral tumor predominance, tumor encapsulation, the existence of residual normal-appearing thymic tissue, and no mass compression effect. All enrollees were expected to be free of pleural effusion, pericardial effusion, paralysis of the hemidiaphragm, and the encasement of great vessels. An elevation of either the serum α-fetoprotein or β-human chorionic gonadotropin levels, severe chest pain, superior vena cava syndrome, hoarseness, and age less than 20 years excluded the patient from enrollment. The heterogeneous content of the tumor was not an exclusion criterion, and the tumor size was not considered important. According to the above criteria, 44 patients were enrolled between November 1999 and November 2005. Twenty-seven patients had stage I thymoma and 17 had stage II thymoma. All patients successfully underwent a complete tumor resection using a three-port endoscopic technique. There was no open conversion. Based on these criteria, we can select suitable patients to confidently perform a thoracoscopic resection of early-stage thymoma. (author)

    Nonoperative management for patients with rectal cancer who have achieved a clinical complete response after chemoradiotherapy is becoming increasingly important in recent years. However, the definition of and modality used for patients with clinical complete response differ greatly between institutions, and the role of endoscopic assessment as a nonoperative approach has not been fully investigated. This study aimed to investigate the ability of endoscopic assessments to predict pathological regression of rectal cancer after chemoradiotherapy and the applicability of these assessments for the watchful waiting approach. This was a retrospective comparative study. This study was conducted at a single referral hospital. A total of 198 patients with rectal cancer underwent preoperative endoscopic assessments after chemoradiotherapy. Of them, 186 patients underwent radical surgery with lymph node dissection. The histopathological findings of resected tissues were compared with the preoperative endoscopic findings. Twelve patients refused radical surgery and chose watchful waiting; their outcomes were compared with the outcomes of patients who underwent radical surgery. The endoscopic criteria correlated well with tumor regression grading. The sensitivity and specificity for a pathological complete response were 65.0% to 87.1% and 39.1% to 78.3%. However, endoscopic assessment could not fully discriminate pathological complete responses, and the outcomes of patients who underwent watchful waiting were considerably poorer than the patients who underwent radical surgery. Eventually, 41.7% of the patients who underwent watchful waiting experienced uncontrollable local failure, and many of these occurrences were observed more than 3 years after chemoradiotherapy. The number of the patients treated with the watchful waiting strategy was limited, and the selection was not randomized. Although endoscopic assessment after chemoradiotherapy correlated with pathological response

    The role of adjuvant radiotherapy for central neurocytomas (CNs) is not clear. Therefore, we aimed to examine the clinical outcomes of treating histologically confirmed CNs with adjuvant RT after surgical resection. Sixty-three CN patients were retrospectively evaluated: 24 patients underwent gross total resection (GTR); 28, subtotal resection (STR); 9, partial resection (PR), and 2, biopsy (Bx). They underwent adjuvant RT after surgery (median dose, 54 Gy). The median follow-up was 69 months (15–129 months). The 5-year overall survival (OS) and 5-year progression-free survival (PFS) were 94.4% and 95% after GTR + RT, 96.4% and 100% after STR + RT, and 100% and 90.9% after PR + RT. Only three patients had tumor recurrence: at the primary site at 30 and 24 months in two GTR + PR patients, and dissemination to the spinal cord at 75 months in one STR + RT patient. Thirty-eight (63.3%) patients experienced late neurotoxicity (28, grade 1; 7, grade 2; 3, grade 3). Short-term memory impairment was the most common toxicity. RT after incomplete resection (IR) led to OS and PFS comparable to those for GTR. Considering the excellent outcomes and limited late toxicity, adjuvant RT maybe a good option for CN patients who undergo IR

    Synchronous/metachronous gastric epithelial neoplasias (GENs) in the remaining lesion can develop at sites other than the site of endoscopic resection. In the present study, we aimed to investigate the predictive value of serum pepsinogen for detecting multiple GENs in patients who underwent endoscopic resection. In total, 228 patients with GEN who underwent endoscopic resection and blood collection for pepsinogen I and II determination were evaluated retrospectively. The mean period of endoscopic follow-up was 748.8±34.7 days. Synchronous GENs developed in 46 of 228 (20.1%) and metachronous GENs in 27 of 228 (10.6%) patients during the follow-up period. Multiple GENs were associated with the presence of pepsinogen I <30 ng/mL (p<0.001). Synchronous GENs were associated with the presence of pepsinogen I <30 ng/mL (p<0.001). Low pepsinogen I levels predict multiple GENs after endoscopic resection, especially synchronous GENs. Cautious endoscopic examination prior to endoscopic resection to detect multiple GENs should be performed for these patients.

    Purpose: Pancreatic neuroendocrine tumors (NET) are rare and have better disease-related outcomes compared with pancreatic adenocarcinoma. Surgical resection remains the standard of care, although many patients present with locally advanced or metastatic disease. Little is known regarding the use of radiotherapy in the prevention of local recurrence after resection. To better define the role of radiotherapy, we performed an analysis of resected patients at our institution. Methods: Between 1994 and 2009, 33 patients with NET of the pancreatic head and neck underwent treatment with curative intent at Duke University Medical Center. Sixteen patients were treated with surgical resection alone while an additional 17 underwent resection with adjuvant or neoadjuvant radiation therapy, usually with concurrent fluoropyrimidine-based chemotherapy (CMT). Median radiation dose was 50.4 Gy and median follow-up 28 months. Results: Thirteen patients (39%) experienced treatment failure. Eleven of the initial failures were distant, one was local only and one was local and distant. Two-year overall survival was 77% for all patients. Two-year local control for all patients was 87%: 85% for the CMT group and 90% for the surgery alone group (p = 0.38). Two-year distant metastasis-free survival was 56% for all patients: 46% and 69% for the CMT and surgery patients, respectively (p = 0.10). Conclusions: The primary mode of failure is distant which often results in mortality, with local failure occurring much less commonly. The role of radiotherapy in the adjuvant management of NET remains unclear.

    Sublobar resection has been increasingly adopted in elderly patients with stage IA non-small cell lung cancer (NSCLC), but the equivalency of sublobar resection versus lobectomy among young patients with stage IA NSCLC is unknown. Using the Surveillance, Epidemiology, and End Results (SEER) registry, we identified patients aged ≤35 years who were diagnosed between 2004 and 2013 with pathological stage IA NSCLC and treated with sublobar resection or lobectomy. We used propensity-score matching to minimize the effect of potential confounders that existed in the baseline characteristics of patients in different treatment groups. The overall survival (OS) and lung cancer-specific survival (LCSS) rates of patients who underwent sublobar resection or lobectomy were compared in stratification analysis. Overall, we identified 188 patients who had stage IA disease, 32 (17%) of whom underwent sublobar resection. We did not identify any difference in OS/LCSS between patients who received sublobar resection versus lobectomy before (log-rank p = 0.6354) or after (log-rank p = 0.5305) adjusting for propensity scores. Similarly, we still could not recognize different OS/LCSS rates among stratified T stage groups or stratified lymph node-removed groups before or after adjusting for propensity scores. Sublobar resection is not inferior to lobectomy for young patients with stage IA NSCLC. Considering sublobar resection better preserves lung function and has reduced overall morbidity, sublobar resection may be preferable for the treatment of young patients with stage IA NSCLC.

    Homologous recombination is initiated by the so-called DNA end resection, the 5'-3' nucleolytic degradation of a single strand of the DNA at each side of the break. The presence of resected DNA is an obligatory step for homologous recombination. Moreover, the amount of resected DNA modulates the prevalence of different recombination pathways. In different model organisms, there are several published ways to visualize and measure with more or less detail the amount of DNA resected. In human cells, however, technical constraints hampered the study of resection at high resolution. Some information might be gathered from the study of endonuclease-created DSBs, in which the resection of breaks at known sites can be followed by PCR or ChIP. In this chapter, we describe in detail a novel assay to study DNA end resection in breaks located on unknown positions. Here, we use ionizing radiation to induce double-strand breaks, but the same approach can be used to monitor resection induced by different DNA damaging agents. By modifying the DNA-combing technique, used for high-resolution replication analyses, we can measure resection progression at the level of individual DNA fibers. Thus, we named the method Single Molecule Analysis of Resection Tracks (SMART). We use human cells in culture as a model system, but in principle the same approach would be feasible to any model organism adjusting accordingly the DNA isolation part of the protocol.

    To suggest the optimal radiation fields after a surgical resection based on a nationwide survey on the principles of radiotherapy for rectal cancer in the Korean Patterns of Care Study. A consensus committee, composed of radiation oncologists from 18 hospitals in Seoul Metropolitan area, developed a survey format to analyze radiation oncologist's treatment principles for rectal cancer after a surgical resection. The survey format included 19 questions on the principles of defining field margins, and was sent to the radiation oncologists in charge of gastrointestinal malignancies in all Korean hospitals (48 hospitals). Thirty three (69%) oncologists replied. On the basis of the replies and literature review, the committee developed guidelines for the optimal radiation fields for rectal cancer. The following guidelines were developed: superior border between the lower tip of the L5 vertebral body and upper sacroiliac joint; inferior border 2-3 cm distal to the anastomosis in patient whose sphincter was saved, and 2-3 cm distal to the perineal scar in patients whose anal sphincter was sacrificed; anterior margin at the posterior tip of the symphysis pubis or 2-3 cm anterior to the vertebral body, to include the internal iliac lymph node and posterior margin 1.5-2 cm posterior to the anterior surface of the sacrum, to include the presacral space with enough margin. Comparison with the guidelines, the replies on the superior margin coincided in 23 cases (70%), the inferior margin after sphincter saving surgery in 13 (39%), the inferior margin after abdominoperineal resection in 32 (97%), the lateral margin in 32 (97%), the posterior margins in 32 (97%) and the anterior margin in 16 (45%). These recommendations should be tailored to each patient according to the clinical characteristics such as tumor location, pathological and operative findings, for the optimal treatment. The adequacy of these guidelines should be proved by following the Korean Patterns of Care

    In patients with unresectable colorectal liver metastases (CLM) resistant to first-line chemotherapy, the impact of cetuximab therapy on resectability is unknown. This study was performed to determine the post-cetuximab resectability rate and to examine postoperative outcomes for these heavily pretreated patients. From February 2004 to April 2006, we evaluated 151 patients with unresectable CLM resistant to initial chemotherapy and subsequently treated with systemic cetuximab. Resectability rates, patient outcomes, and tumoral and nontumoral liver pathology were assessed. A total of 27 patients underwent surgery after a median of six cycles of cetuximab + irinotecan (20 of 27), oxaliplatin (four of 27), or both (one of 27). Eighteen patients (67%) had experienced treatment failure after at least two lines of chemotherapy before cetuximab. Twenty-five of the 27 patients who had surgery underwent hepatectomy: nine of 133 patients who were treated completely at our institution (resectability rate, 7%) and 16 of 18 patients who were referred from other institutions after systemic cetuximab therapy. Postoperative mortality was 3.7% (one of 27), with a complication rate of 50%. Histopathologic liver abnormalities were found in nine patients (36%), without specific lesions attributable to cetuximab. After median follow-up of 16 months, 23 of 25 patients who underwent resection (92%) were alive, and 10 patients (40%) were disease free. Median overall (OS) and progression-free survival (PFS) from initiation of cetuximab therapy were 20 and 13 months, respectively. For CLM refractory to conventional chemotherapy, combination therapy with cetuximab increases resectability rates without increasing operative mortality or liver injury. The median OS and PFS of 20 and 13 months, respectively, suggest that this novel oncosurgical strategy benefits patients with previously refractory disease who respond subsequently to cetuximab.

    To explore the relationship between the amount of resected Müller's muscle-conjunctiva (MMCR) and clinical outcome in patients undergoing upper eyelid ptosis surgery. 49 patients underwent 87 MMCR surgeries. The total areas of the specimen and of MM were measured in pixels. The average percentage of muscle tissue in relation to total excised tissue was 21%. Intraoperative MMC tissue measurements and postoperative improvement in eyelid position (delta marginal reflex distance 1 (MRD1)) were positively correlated (R=0.427, p=0.09). There was a weak correlation between total areas measured on the histological slides and the intraoperative MMCR values (R=0.3, p=0.057). Total histological areas did not correlate with the delta change in eyelid position or with the amount and percentage of resected muscle tissue and the extent of improvement in eyelid position (delta MRD1) or final eyelid position (postoperative MRD1). Post-MMCR improvement in eyelid positions did not correlate with the percentage of MM in the excised tissue. We believe that the mechanism responsible for surgical outcome is plication or scarring of the posterior lamella and not the amount of resected MM. More lift in eyelid position can be anticipated when more tissue is excised by MMCR, and not when more muscle is excised.

    The safety and efficacy of surgical resection of lung nodule without tissue diagnosis is controversial. We evaluated direct surgical resection of highly suspicious pulmonary nodules and the clinical and radiological predictors of malignancy. Retrospective analyses were performed on 113 patients who underwent surgical resection without prior tissue diagnosis for highly suspicious pulmonary nodules. Clinical and radiological characteristics were compared between histologically proven benign and malignant nodules after resection. Total costs, length of hospitalization and waiting time to surgery were compared with those of patients who had tissue diagnosis prior to surgery. Among 280 patients with pulmonary nodules suspicious for lung cancer, 113 (40.4%) underwent operation without prior tissue diagnosis. Lung nodules were diagnosed as malignant in 96 (85%) of the 113 patients. Except for forced expiratory volume in 1 s, clinical characteristics were not significantly different according to the pathologic results. Forty-five (90%) of 50 patients with ground-glass opacity nodules had a malignancy. Mixed ground-glass opacity, bubble lucency, irregular margin and larger size correlated with malignancy in ground-glass opacity nodules (P<0.05). Fifty-one (81%) of 67 patients with solid nodules had a malignancy. Spiculation, pre-contrast attenuation and contrast enhancement significantly correlated with malignancy in solid nodules (P<0.05). Surgical resection without tissue diagnosis significantly decreased total costs, hospital stay and waiting time (P<0.05). Direct surgical resection of highly suspicious pulmonary nodules can be a valid procedure. However, careful patient selection and further investigations are required to justify direct surgical resection. (author)

    Full Text Available Background and Aims. Biliary complications are the most frequent complications after common liver surgeries. In this study, accuracy of hepatobiliary scintigraphy (HBS and impact of hyperbilirubinemia were evaluated. Methods. Between November 2007 and February 2016, 131 patients underwent hepatobiliary scintigraphy after having liver surgery. 39 patients with 42 scans after LTX (n=13 or hepatic resection (n=26 were evaluated in the study; 27 were male, with mean age 60 years. The subjects underwent hepatobiliary scintigraphy with Tc-99m labeled Mebrofenin. The results were compared to ERCP as gold standard performed within one month after HBS. We calculated sensitivity, specificity, PPV, and NPV. We compared LTX patients to patients with other liver surgeries. Furthermore the influence of hyperbilirubinemia on HBS scans was evaluated. Results. HBS always provided the correct diagnosis in cases of bile leak in the liver-resected group (14/14. Overall diagnostic accuracy was 76% (19/25 in this group and 54% (7/13 in the LTX group. False negative (FN diagnoses occurred more often among LTX patients (p=0.011. Hyperbilirubinemia (>5 mg/dL significantly influenced the excretion function of the liver, prolonging HBS’s time-activity-curve (p=0.001. Conclusions. Hepatobiliary scintigraphy is a reliable tool to detect biliary complications, but reduced accuracy must be considered after LTX.

    The aim of this study was to review a series of patients submitted to hepatectomy for primary intrahepatic lithiasis to evaluate early and late results with an assessment of indications, methods and long-term outcomes. From January 1992 to December 2007, 40 patients (25 males and 15 females with a mean age of 51 years) underwent surgery for primary intrahepatic lithiasis in our Hepato-biliary Surgery Unit. Left hepatectomy (20 patients) and left lateral segmentectomy (12 patients) were the most common procedures performed. A cholangiocarcinoma was found in 4 patients (10%) and only two of these underwent liver resection, while an exploratory laparotomy was performed in the remaining two patients for an unresectable tumour, unexpected before surgery. There was no postoperative mortality. The morbidity rate was 22.5% with a prevalence of infectious complications related to bile leakage. Long-term results, assessed in 30 patients with a follow-up longer than 12 months, were good or fair in 28 patients (93.3%). Primary intrahepatic lithiasis is diagnosed increasingly in Western countries as a result of the improvement in imaging techniques. The stones originate inside the liver at the level of dilatations of the bile ducts above congenital strictures of the main hilar ducts. Biliary pain and cholangitis are the most common presenting symptoms, whereas cholangiocarcinoma represents the unfavourable complication of the disease. In the majority of cases, a single liver lobe or segment is involved and liver resection allows definitive treatment of the disease and prevention of cancer.

    Laparoscopic and endoluminal surgical techniques have evolved and allowed improvements in the methods for treating benign and malignant gastrointestinal diseases. To date, only case reports have been reported on the application of a laparo-endoscopic approach for resecting gastric submucosal tumors (SMT). In this study, we aimed to evaluate the efficacy, safety, and oncologic outcomes of a laparo-endoscopic transgastric approach to resect tumors that would traditionally require either a laparoscopic or open surgical approach. Herein, we present the largest single institution series utilizing this technique for the resection of gastric SMT in North America. We performed a retrospective review of a prospectively collected patient database. Patients who presented for evaluation of gastric SMT were offered this surgical procedure and informed consents were obtained for participation in the study. Fourteen patients were included in this study between August/2010 and January/2013. Eight (8) patients (57.1 %) were female and the median age was 56 years (range 29-78). Of the 14 cases, 8 patients (57.1 %) underwent laparo-endoscopic resection of SMTs with transgastric extraction, 5 patients (35.7 %) had conversions to traditional laparoscopic surgery, and 1 patient (7.2 %) was abandoned intraoperatively. The median operative time for this cohort was 80 min (range 35-167). Ten patients (71.4 %) had GISTs, 3 (21.4 %) had leiomyomas, and 1 (7.1 %) had schwannoma. There were no intraoperative complications. Two patients had postoperative staple line bleeding that required repeat endoscopy. The median hospital stay was 1 day (range 1-6) and there were no postoperative mortalities. At 12-month follow-up visit, only one GIST patient (10 %) had tumor recurrence. Our experience suggests that this surgical approach is safe and efficient in the resection of gastric SMT with transgastric extraction. This study found no intraoperative complications and optimal oncologic outcomes during

    To assess the safety, feasibility and clinical outcome of laparoscopic radical resection for low rectal cancer with telescopic anastomosis or with colostomy by stapler through transanal resection without abdominal incisions. From January 2010 to September 2014, 37 patients underwent laparoscopic radical resection for low rectal cancer through transanal resection without abdominal incisions. The tumors were 4-7 cm above the anal verge. On preoperative assessment, 26 cases were T1N0M0 and 11 were T2N0M0. For all cases, successful surgery was performed. In telescopic anastomosis group, the mean operative time was (178±21) min, with average blood loss of (76±11) ml and (13±7) lymph nodes harvested. Return of bowel function was (3.0±1.2) d and the hospital stay was (12.0±4.2) d without postoperative complications. Patients were followed up for 3-45 months. Twelve months after surgery, 94.6%(35/37) patients achieved anal function Kirwan grade 1, indicating that their anal function returned to normal. Laparoscopic radical resection for low rectal cancer with telescopic anastomosis or colostomy by stapler through transanal resection without abdominal incisions is safe and feasible. Satisfactory clinical outcome can be achieved mini-invasively.

    To benchmark severity of complications using the Accordion Severity Grading System (ASGS) in patients undergoing operation for severe pancreatic injuries. A prospective institutional database of 461 patients with pancreatic injuries treated from 1990 to 2015 was reviewed. One hundred and thirty patients with AAST grade 3, 4 or 5 pancreatic injuries underwent resection (pancreatoduodenectomy, n = 20, distal pancreatectomy, n = 110), including 30 who had an initial damage control laparotomy (DCL) and later definitive surgery. AAST injury grades, type of pancreatic resection, need for DCL and incidence and ASGS severity of complications were assessed. Uni- and multivariate logistic regression analysis was applied. Overall 238 complications occurred in 95 (73%) patients of which 73% were ASGS grades 3-6. Nineteen patients (14.6%) died. Patients more likely to have complications after pancreatic resection were older, had a revised trauma score (RTS) < 7.8, were shocked on admission, had grade 5 injuries of the head and neck of the pancreas with associated vascular and duodenal injuries, required a DCL, received a larger blood transfusion, had a pancreatoduodenectomy (PD) and repeat laparotomies. Applying univariate logistic regression analysis, mechanism of injury, RTS < 7.8, shock on admission, DCL, increasing AAST grade and type of pancreatic resection were significant variables for complications. Multivariate logistic regression analysis however showed that only age and type of pancreatic resection (PD) were significant. This ASGS-based study benchmarked postoperative morbidity after pancreatic resection for trauma. The detailed outcome analysis provided may serve as a reference for future institutional comparisons.

    Full Text Available Abstract Leiomyosarcoma of the inferior vena cava (IVCL is a rare retroperitoneal tumor. We report two cases of level II (middle level, renal veins to hepatic veins IVCL, who underwent en bloc resection with reconstruction of bilateral or left renal venous return using prosthetic grafts. In our cases, IVCL is documented to be occluded preoperatively, therefore, radical resection of tumor and/or right kidney was performed and the distal end of inferior vena cava was resected and without caval reconstruction. None of the patients developed edema or acute renal failure postoperatively. After surgical resection, adjuvant radiation therapy was administrated. The patients have been free of recurrence 2 years and 3 months, 9 months after surgery, respectively, indicating the complete surgical resection and radiotherapy contribute to the better survival. The reconstruction of inferior vena cava was not considered mandatory in level II IVCL, if the retroperitoneal venous collateral pathways have been established. In addition to the curative resection of IVCL, the renal vascular reconstruction minimized the risks of procedure-related acute renal failure, and was more physiologically preferable. This concept was reflected in the treatment of the two patients reported on.

    Objective Up to a third of all infants who develop necrotizing enterocolitis (NEC) require surgical resection of necrotic bowel. We hypothesized that the histopathological findings in surgically-resected bowel can predict the clinical outcome of these infants. Study design We reviewed the medical records and archived pathology specimens from all patients who underwent bowel resection/autopsy for NEC at a regional referral center over a 10-year period. Pathology specimens were graded for the depth and severity of necrosis, inflammation, bacteria invasion, and pneumatosis, and histopathological findings were correlated with clinical outcomes. Results We performed clinico-pathological analysis on 33 infants with confirmed NEC, of which 18 (54.5%) died. Depth of bacterial invasion in resected intestinal tissue predicted death from NEC (odds ratio 5.39 per unit change in the depth of bacterial invasion, 95% confidence interval 1.33-21.73). The presence of transmural necrosis and bacteria in the surgical margins of resected bowel was also associated with increased mortality. Conclusions Depth of bacterial invasion in resected intestinal tissue predicts mortality in surgical NEC. PMID:25950918

    Background and purpose: To evaluate the impact of intraoperative radiotherapy (IORT) combined with postoperative external beam irradiation in patients with pancreatic cancer treated with curative surgical resection. Materials and methods: From January 1986 to April 1995 25 patients (11 male and 14 female, median age 61 years) underwent a curative resection with IORT for pancreatic adenocarcinoma. The tumour was located in the head of the pancreatic gland in 22 patients, in the body in two patients and in the tail in one patient. The pathological stage was pT1 in nine patients, pT2 in nine patients, pT3 in seven patients, pN0 in 14 patients and pN1 in 11 patients. All the patients were pM0. A pancreaticoduodenectomy was performed in 22 patients, a distal pancreatectomy was performed in two patients and a total pancreatectomy was performed in one patient. The resection was considered to be complete in 20 patients. One patient had microscopic residual disease and gross residual disease was present in four patients. IORT using electrons with a median energy of 12 MeV was performed in all the patients with doses ranging from 12 to 25 Gy. Postoperative EBRT was delivered to 20 patients (median dose 44 Gy). Concurrent chemotherapy with 5-fluorouracil was given to seven patients. Results: The overall survival was 56% at 1 year, 20% at 2 years and 10% at 5 years. Nine local failures were observed. Twelve patients developed metastases without local recurrence. Twenty patients died from tumour progression and two patients died from early post-operative complications. Three patients are still alive; two patients in complete response at 17 and 94 months and one patient with hepatic metastases at 13 months. Conclusion: IORT after complete resection combined with postoperative external beam irradiation is feasible and well tolerated in patients with pancreatic adenocarcinoma

    Full Text Available BackgroundAggressive treatment of sternoclavicular joint (SCJ infection involves systemic antibiotics, surgical drainage and resection if indicated. The purpose of this paper is to describe a classification of post resectional SCJ defects and highlight our reconstructive algorithm. Defects were classified into A, where closure was possible often with the aid of topical negative pressure dressing; B, where parts of the manubrium, calvicular head, and first rib were excised; and C, where both clavicular, first ribs and most of the manubrium were resected.MethodsTwelve patients (age range, 42 to 72 years over the last 8 years underwent reconstruction after SCJ infection. There was 1 case of a type A defect, 10 type B defects, and 1 type C defect. Reconstruction was performed using the pectoralis major flap in 6 cases (50%, the latissimus dorsi flap in 4 cases (33%, secondary closure in 1 case and; the latissimus and the rectus flap in 1 case.ResultsAll wounds healed uneventfully with no flap failure. Nine patients had good shoulder motion. Three patients with extensive clavicular resection had restricted shoulder abduction and were unable to abduct their arm past 90°. Internal and external rotation were not affected.ConclusionsWe highlight our reconstructive algorithm which is summarised as follows: for an isolated type B SCJ defect we recommend the ipsilateral pectoralis major muscle for closure. For a type C bilateral defect, we suggest the latissimum dorsi flap. In cases of extensive infection where the thoracoacromial and internal mammary vessels are thrombosed, the pectoralis major and rectus abdominus cannot be used; and the latissimus dorsi flap is chosen.

    Transanal endoscopic microsurgery is considered a safe, appropriate, and minimally invasive approach, and complications after endoscopic microsurgery are rare. We report a case of sepsis and pneumoretroperitoneum after resection of a rectal lateral spreading tumor. The patient presented with rectal mucous discharge. Colonoscopy revealed a rectal lateral spreading tumor. The patient underwent an endoscopic transanal resection of the lesion. He presented with sepsis of the abdominal focus, and imaging tests revealed pneumoretroperitoneum. A new surgical intervention was performed with a loop colostomy. Despite the existence of other reports on pneumoretroperitoneum after transanal endoscopic microsurgery, what draws attention to this case is the association with sepsis.

    Standard approach for medically stable advanced ovarian cancer patients should be primary cytoreduction following platinum-based chemotherapy. The aim of surgical effort should be the complete removal of all visible disease. Our objective was to compare perioperative features, postoperative complications, and secondarily oncological outcomes of patients who underwent diaphragmatic stripping with those who underwent diaphragmatic resection for advanced ovarian cancer. One hundred twelve cases were identified, among them 79 underwent diaphragmatic stripping and 33 underwent diaphragmatic full-thickness resection. Data collected included patients' age, all perioperative details and pathological findings, International Federation of Gynecology and Obstetrics stage, adjuvant therapy, and follow-up data. Larger residual tumors (mean, 5.1 vs 1.6 mm, respectively; P < 0.01) but shorter operating time (25 minutes shorter operative time, P = 0.07) were observed in the stripping group. Higher postoperative pleural effusions rates (63.6% vs 37.9%, P = 0.01), but no differences in the remaining complications, were observed in the resection group. After a mean of 31 months of follow-up, disease-free survival rates were 27.8% in the stripping group and 39.4% in the resection group (P = 0.04). No significant differences were observed for overall survival. Diaphragmatic surgery at the time of primary cytoreductive surgery for advanced ovarian cancer may contribute to the achievement of complete cytoreduction with low perioperative complication rate; full-thickness resection is preferable if peritoneum stripping will not achieve a complete removal of the disease.

    Treatment of metastatic colon cancer may be driven as much by practice patterns as by features of disease. To optimize management, there is a need to better understand what is determining primary site resection use. We evaluated all patients with stage IV cancers in the National Cancer Data Base from 2002 to 2012 (50,791 patients, 1,230 hospitals). We first identified patient characteristics associated with primary tumor resection. Then, we assessed nationwide variation in hospital resection rates. Overall, 27,387 (53.9%) patients underwent primary site resection. Factors associated with resection included younger age, having less than 2 major comorbidities, and white race (P < .001). Nationwide, hospital-adjusted primary tumor resection rates ranged from 26.0% to 87.8% with broad differences across geographical areas and hospital accreditation types. There is statistically significant variation in hospital rates of primary site resection. This demonstrates inconsistent adherence to guidelines in the presence of conflicting evidence regarding resection benefit. Copyright © 2016 Elsevier Inc. All rights reserved.

    Prolonged air leak (PAL) after anatomic lung resection is a common and challenging complication in thoracic surgery. No available clinical prediction model of PAL has been established in China. The aim of this study was to construct a model to identify patients at increased risk of PAL by using preoperative factors exclusively. We retrospectively reviewed clinical data and PAL occurrence of patients after anatomic lung resection, in department of thoracic surgery, Anhui Provincial Hospital Affiliated to Anhui Medical University, from January 2016 to October 2016. 359 patients were in group A, clinical data including age, body mass index (BMI), gender, smoking history, surgical methods, pulmonary function index, pleural adhesion, pathologic diagnosis, side and site of resected lung were analyzed. By using univariate and multivariate analysis, we found the independent predictors of PAL after anatomic lung resection and subsequently established a clinical prediction model. Then, another 112 patients (group B), who underwent anatomic lung resection in different time by different team, were chosen to verify the accuracy of the prediction model. Receiver-operating characteristic (ROC) curve was constructed using the prediction model. Multivariate Logistic regression analysis was used to identify six clinical characteristics [BMI, gender, smoking history, forced expiratory volume in one second to forced vital capacity ratio (FEV1%), pleural adhesion, site of resection] as independent predictors of PAL after anatomic lung resection. The area under the ROC curve for our model was 0.886 (95%CI: 0.835-0.937). The best predictive P value was 0.299 with sensitivity of 78.5% and specificity of 93.2%. Our prediction model could accurately identify occurrence risk of PAL in patients after anatomic lung resection, which might allow for more effective use of intraoperative prophylactic strategies.

    Pancreatic cancer has a dismal prognosis. A technically perfect surgical operation may still not provide a survival advantage for patients with technically resectable pancreatic cancer. Appropriate selection of patients for surgical resections is an imminent issue. Recent studies have provided an important clue on what serum biomarkers may be used to select out the patients who would unlikely benefit from the surgical resection.

    The aim of this study was to review our experience with laparoscopic sigmoid colectomy for diverticular disease. All patients presenting with acute or chronic diverticulitis, obstruction, abscess, or fistula were included. Symptomatic diverticular disease was the main surgical indication (95%). Between March 1992 and August 1999 170 consecutive patients underwent surgery. Of these, 21 patients (12%) had significant obesity, with body mass index (BMI) greater than 30. The average length of surgery was 141 +/- 36 min. In 163 patients (96%), the procedure was performed solely with the laparoscope. The nasogastric tube was removed on postoperative day 2 +/- 1.9, and oral feeding was started on postoperative day 3.4 +/- 2.1. The average length of hospital stay after surgery was 8.5 +/- 3.7 days. During the first postoperative month, there were no deaths. However, 11 patients (6.5%) had surgical complications: 5 anastomotic leaks (2.9%), 1 intraabdominal abscess (0.6%), and 3 wound infections (1.7%). There were four reinterventions (2.4%), with two diverting colostomies. Secondarily, 10 anastomotic stenoses (5.9%) were observed. Eight patients required a reintervention: seven anastomotic resections by open laparotomy and one terminal colostomy. Seven patients (4.1%) reported retrograde ejaculation, and one reported impotence. The feasibility of the laparoscopic approach to diverticular disease is established with a conversion rate of 4%, a low incidence of acute septic complications (5.3%), and a mortality rate of 0%. Therefore, laparoscopic sigmoid colectomy has become our procedure of choice in the treatment of diverticular disease.

    Subxiphoid uniportal video-assisted thoracic surgery (SVATS) for major lung resections is a new approach. Clinical evidence is lacking. The aim of this article is to describe the learning curve of the 200 selected patients who underwent uniportal subxiphoid lobectomy or segmentectomy by subxiphoid midline incision, and with the lessons learned from this early experience in SVATS and from the experience with transthoracic uniportal VATS we sought to compile "tips and tricks" for managing the multiple intraoperative technical difficulties that can arise during the SVATS and help to set the recommendations for a SVATS program. We describe the learning curve of the first 200 selected patients who underwent uniportal subxiphoid lobectomy or segmentectomy by subxiphoid midline incision From September 2014 with early-stage non-small cell lung carcinoma (NSCLC) and benign disease. We examine the rate of conversion and the operating time comparing group one (first 100 cases) with group two (subsequent 100 cases). Of the 200 consecutive selected cases (72 males, 128 females) with a mean age of 57.4±9 years, underwent either uniportal subxiphoid lobectomy or segmentectomy 136 were lobectomies and 64 were segmental resections The mean operating time was 170±45 mins; the average and after the case 86 the rate of the operating time appears to be similar. The conversion rate decrease from 13% in group one to 8% in group two. There is a gradual reduction in the operating time and rate conversion with increasing experience. Lessons from our initial experience in the learning curve period in SVATS helps to create this trouble shooting guide that offers "tips and tricks" to both avoid and manage numerous intra-operative technical difficulties that commonly arise during the SVATS initial experience.

    The failure rate after arthroscopic meniscal repair ranges from 5% to 43.5% (mean, 15%) in the literature. But little is known about the amount of meniscal tissue removed after failed meniscal repair. The volume of subsequent meniscectomy after failed meniscal repair is not increased when compared with the volume of meniscectomy that would have been performed if not initially repaired. Case series; Level of evidence, 4. From January 2000 to December 2009, 295 knees underwent arthroscopic meniscal repair for unstable peripheral vertical tears. When present (219 cases), all anterior cruciate ligament (ACL) tears underwent reconstruction. Patients with multiple ligament injuries and posterior cruciate ligament injuries were excluded from the analysis. Thirty-two medial and 5 lateral menisci underwent subsequent meniscectomy after failed repair at a mean of 26 months postoperatively (range, 3-114 months). Five parameters were specifically evaluated: the amount of meniscectomy related to the initial tear, the ACL status, the appearance of chondral lesions, the time from the initial injury to meniscal repair, and the time from repair to meniscectomy. The posterior segment of the meniscus was involved in all tears and retears. Among failures, resection of the meniscal segments primarily repaired occurred for 17 medial and 2 lateral meniscal tears (52%); the tear extended in 5 cases (all medial menisci), and healing of some repaired segments led to a partial resection of the initial lesion in 35% of cases (10 medial menisci, 3 lateral menisci). The time from injury to meniscal repair was correlated with an increasing volume of meniscus removed (P lesions at revision (P meniscal lesion, even if it fails. The amount of meniscectomy is rarely increased when compared with the initial lesion. This study supports the hypothesis that the meniscus can be partially saved and that a risk of a partial failure should be taken when possible.

    AIM To benchmark severity of complications using the Accordion Severity Grading System (ASGS) in patients undergoing operation for severe pancreatic injuries. METHODS A prospective institutional database of 461 patients with pancreatic injuries treated from 1990 to 2015 was reviewed. One hundred and thirty patients with AAST grade 3, 4 or 5 pancreatic injuries underwent resection (pancreatoduodenectomy, n = 20, distal pancreatectomy, n = 110), including 30 who had an initial damage control laparotomy (DCL) and later definitive surgery. AAST injury grades, type of pancreatic resection, need for DCL and incidence and ASGS severity of complications were assessed. Uni- and multivariate logistic regression analysis was applied. RESULTS Overall 238 complications occurred in 95 (73%) patients of which 73% were ASGS grades 3-6. Nineteen patients (14.6%) died. Patients more likely to have complications after pancreatic resection were older, had a revised trauma score (RTS) trauma. The detailed outcome analysis provided may serve as a reference for future institutional comparisons. PMID:28396721

    Controlling Nutritional Status (CONUT), as calculated from serum albumin, total cholesterol concentration, and total lymphocyte count, was previously shown to be useful for nutritional assessment. The current study investigated the potential use of CONUT as a prognostic marker in gastric cancer patients after curative resection. Preoperative CONUT was retrospectively calculated in 416 gastric cancer patients who underwent curative resection at Kumamoto University Hospital from 2005 to 2014. The patients were divided into two groups: CONUT-high (≥4) and CONUT-low (≤3), according to time-dependent receiver operating characteristic (ROC) analysis. The associations of CONUT with clinicopathological factors and survival were evaluated. CONUT-high patients were significantly older (p nutritional status but also for predicting long-term OS in gastric cancer patients after curative resection.

  16. Computed tomography-guided cryoablation of local recurrence after primary resection of pancreatic adenocarcinoma

    2015-06-01

    Full Text Available The optimal management of local recurrences after primary resection of pancreatic cancer still remains to be clarified. A 58-yearold woman developed an isolated recurrence of pancreatic cancer six year after distal pancreatectomy. Re-resection was attempted but the lesion was deemed unresectable at surgery. Then chemotherapy was administrated without obtaining a reduction of the tumor size nor an improvement of the patient’s symptoms. Thus the patient underwent percutaneous cryoablation under computed tomography (CT-guidance obtaining tumor necrosis and a significant improvement in the quality of life. A CT scan one month later showed a stable lesion with no contrast enhancement. While the use of percutaneous cryoblation has widened its applications in patients with unresectable pancreatic cancer, it has never been described for the treatment of local pancreatic cancer recurrence after primary resection. Percutaneous cryoablation deserves further studies in the multimodality treatment of local recurrence after primary pancreatic surgery.

    Laparoscopic resection of the transplanted kidney has been very rarely reported in the literature. On the one hand, this is due to the extremely low incidence of tumors of renal transplants. On the other hand, these patients are usually managed by open surgery due to difficulties in laparoscopic resection because of the scar tissue in the kidney area. Other options, though rarely performed, are cryosurgery and radiofrequency ablation of the tumor. In this article we report our own experience with a patient who underwent laparoscopic resection of renal transplant for renal cell carcinoma T1aN0M0 19 years after kidney transplantation. The tumor sized 27 cm was found incidentally by routine ultrasound. The operative time was 115 minutes, the renal ischemia time - 28 min. No intra- and postoperative complications were observed. Histological examination revealed renal cell carcinoma, surgical margins were negative. The patient was discharged on the 7th day after the surgery, no graft dysfunction was observed.

  20. Biliary Stricture Following Hepatic Resection

    Directory of Open Access Journals (Sweden)

    Jeffrey B. Matthews

    1991-01-01

    Full Text Available Anatomic distortion and displacement of hilar structures due to liver lobe atrophy and hypertrophy occasionally complicates the surgical approach for biliary stricture repair. Benign biliary stricture following hepatic resection deserves special consideration in this regard because the inevitable hypertrophy of the residual liver causes marked rotation and displacement of the hepatic hilum that if not anticipated may render exposure for repair difficult and dangerous. Three patients with biliary stricture after hepatectomy illustrate the influence of hepatic regeneration on attempts at subsequent stricture repair. Following left hepatectomy, hypertrophy of the right and caudate lobes causes an anteromedial rotation and displacement of the portal structures. After right hepatectomy, the rotation is posterolateral, and a thoracoabdominal approach may be necessary for adequate exposure. Radiographs obtained in the standard anteroposterior projection may be deceptive, and lateral views are recommended to aid in operative planning.

    Introduction  We sought to identify factors associated with increased length of stay (LOS) and morbidity in patients undergoing resection of pituitary macroadenomas. Methods  We reviewed records of 203 consecutive patients who underwent endoscopic endonasal resection of a pituitary macroadenoma (mean age = 55.7 [16-88]) years, volume = 11.3 (1.0-134.3) cm 3 . Complete resection was possible in 60/29.6% patients. Mean follow-up was 575 days. Multivariate logistic regression was performed using MATLAB. Results  Mean LOS was 4.67 (1-66) days and was associated with CSF leak ( p  = 0.025), lumbar drain placement ( p  = 0.041; n  = 8/3.9% intraoperative, n  = 20/9.9% postoperative), and any infection ( p  = 0.066). Age, diabetes insipidus ( n  = 17/8.37%), and syndrome of inappropriate antidiuretic hormone secretion ( n  = 12/5.9%) were not associated with increased LOS ( p  > 0.2). Postoperative CSF leak in the hospital ( n  = 21/10.3%) was associated with intraoperative CSF leak ( p  = 0.002; n  = 82/40.4%) and complete resection ( p  = 0.012). There was no significant association ( p  > 0.1) between postoperative CSF leak in the hospital following surgery and the use of a fat graft ( n  = 61/30.1%), nasoseptal flap (155/76.4%), or perioperative lumbar drain placement ( n  = 8/3.94%). Conclusion  Complete resection is associated with increased risk of CSF leak and LOS. Operative strategies including placement of fat graft, nasoseptal flap, or intraoperative lumbar drain placement may have limited value in reducing the risk of postoperative CSF leak.

    Preoperative jaundice is frequent in gallbladder cancer (GBC) and indicates advanced disease. Resection is rarely recommended to treat advanced GBC. An aggressive surgical approach for advanced GBC remains lacking because of the association of this disease with serious postoperative complications and poor prognosis. This study aims to re-assess the prognostic value of jaundice for the morbidity, mortality, and survival of GBC patients who underwent surgical resection with curative intent. GBC patients who underwent surgical resection with curative intent at a single institution between January 2003 and December 2012 were identified from a prospectively maintained database. A total of 192 patients underwent surgical resection with curative intent, of whom 47 had preoperative jaundice and 145 had none. Compared with the non-jaundiced patients, the jaundiced patients had significantly longer operative time (p jaundice was the only independent predictor of postoperative complications. The jaundiced patients had lower survival rates than the non-jaundiced patients (p jaundiced patients. The survival rates of the jaundiced patients with preoperative biliary drainage (PBD) were similar to those of the jaundiced patients without PBD (p = 0.968). No significant differences in the rate of postoperative intra-abdominal abscesses were found between the jaundiced patients with and without PBD (n = 4, 21.1% vs. n = 5, 17.9%, p = 0.787). Preoperative jaundice indicates poor prognosis and high postoperative morbidity but is not a surgical contraindication. Gallbladder neck tumors significantly increase the surgical difficulty and reduce the opportunities for radical resection. Gallbladder neck tumors can independently predict poor outcome. PBD correlates with neither a low rate of postoperative intra-abdominal abscesses nor a high survival rate.

    In this study, the authors introduce and evaluate the feasibility of endoscopic resection using the retroauricular approach for various benign lesions of the upper neck. A retrospective comparative analysis was performed on the clinical outcomes of patients who underwent surgery for upper neck masses as endoscopic resection using the retroauricular approach or conventional transcervical resection at the authors' center from January 2010 through August 2011. The primary outcome was the cosmetic satisfaction of the patients in each group. In addition, the feasibility of the procedure was evaluated by comparing the operation time; hospital stay; amount and duration of drainage; complications such as marginal mandibular nerve, lingual, or hypoglossal nerve palsy; paresthesia of the ear lobe; and wound problems such as hematoma and skin necrosis. Statistical analysis was performed by independent-samples t test and the Fisher exact test, and a P value less than .05 was considered statistically significant. Thirty-six patients underwent endoscopic resection (endo group; 15 men, 21 women; mean age, 38.8 ± 15.0 years) and 40 patients underwent conventional transcervical resection (conventional group; 18 men, 22 women; mean age, 45.1 ± 14.1 years). The operating time in the endo group was longer than in the conventional group (P = .003). No significant difference was observed in the overall perioperative complications between the 2 groups. Cosmetic satisfaction evaluated with a graded scale showed much better results in the endo group (P cosmetic results. Copyright © 2013 American Association of Oral and Maxillofacial Surgeons.

    En bloc bladder resection is often required for treating colorectal cancer with suspected urinary bladder invasion. Our aim was to review our institutional experience in en bloc resection of locally advanced colorectal cancer involving the urinary bladder over a period of 17 years. The hospital records of 72 patients with locally advanced colorectal cancer who underwent en bloc urinary bladder resection at our institution between July 1987 and December 2004 were retrospectively reviewed. Clinical and oncologic outcomes were evaluated. The mean duration of follow-up was 64.3 months. Genuine tumor invasion into the urinary bladder was confirmed in 34 patients (47%) by histopathology. Forty patients (56%) underwent primary closure of the urinary bladder, while 32 patients (44%) required various kinds of urologic reconstructive procedures. Operative mortality occurred in four patients (6%). The overall postoperative morbidity rate was significantly higher in patients undergoing urologic reconstruction (81% vs. 45%, p = 0.002) when compared to that in patients undergoing primary closure. This was mostly attributable to significantly higher rates of urinary anastomotic leak (21.9% vs. 0%, p = 0.002) and urinary tract infection (50% vs. 18%, p = 0.003) in the urologic reconstruction group. For the 57 patients (79%) who underwent curative resection, the 5-year overall survival rate was 59%, and the local recurrence at 5 years was 15%. Both parameters were not significantly affected by the presence of pathologic bladder invasion or the extent of surgical procedures. En bloc bladder resection for locally advanced colorectal cancer involving the urinary bladder can produce reasonable long-term local control and patient survival.

    Functional magnetic resonance imaging can demonstrate the functional anatomy of cognitive processes. In patients with refractory temporal lobe epilepsy, evaluation of preoperative verbal and visual memory function is important as anterior temporal lobe resections may result in material specific memory impairment, typically verbal memory decline following left and visual memory decline after right anterior temporal lobe resection. This study aimed to investigate reorganization of memory functions in temporal lobe epilepsy and to determine whether preoperative memory functional magnetic resonance imaging may predict memory changes following anterior temporal lobe resection. We studied 72 patients with unilateral medial temporal lobe epilepsy (41 left) and 20 healthy controls. A functional magnetic resonance imaging memory encoding paradigm for pictures, words and faces was used testing verbal and visual memory in a single scanning session on a 3T magnetic resonance imaging scanner. Fifty-four patients subsequently underwent left (29) or right (25) anterior temporal lobe resection. Verbal and design learning were assessed before and 4 months after surgery. Event-related functional magnetic resonance imaging analysis revealed that in left temporal lobe epilepsy, greater left hippocampal activation for word encoding correlated with better verbal memory. In right temporal lobe epilepsy, greater right hippocampal activation for face encoding correlated with better visual memory. In left temporal lobe epilepsy, greater left than right anterior hippocampal activation on word encoding correlated with greater verbal memory decline after left anterior temporal lobe resection, while greater left than right posterior hippocampal activation correlated with better postoperative verbal memory outcome. In right temporal lobe epilepsy, greater right than left anterior hippocampal functional magnetic resonance imaging activation on face encoding predicted greater visual memory decline

    A 67-year-old woman, who was diagnosed with ovarian cancer with multiple metastases, underwent abdominal total hysterectomy, bilateral salpingo-oophorectomy, para-aortic lymph node dissection(b2), omental subtotal hysterectomy, and lower anterior rectal resection after receiving a combination of PTX plus CBDCA chemotherapy. Macroscopically, complete resection was achieved and histopathological examination of the resectedspecimen showedpoorly differentiatedserous adenocarcinoma. After surgery, additional chemotherapy was administered. However, increasing only lesser curvature of stomach lymph node, we performed laparoscopic lymph node resection as debulking surgery. It is often said that macroscopic complete resection of ovarian cancer improves the prognosis. In particular, we hope that this patient will survive longer with a sustainable quality of life as a result of laparoscopic stomach- andnerve -sparing surgery.

    To evaluate the effect of dienogest (DNG) in preventing the occurrence of pain and endometriomas after laparoscopic resection of uterosacral ligaments (USLs) with deep infiltrating endometriosis (DIE). This retrospective analysis included 126 patients who underwent laparoscopic resection of USLs with DIE followed by postoperative administration of DNG or no medication. Every 6 months postoperatively, patients answered questions and underwent ultrasound examination to identify pain and/or endometrioma. There were three (5.0%) cases of endometrioma in 59 patients from the DNG group and 21 (31.3%) cases in 67 patients from the no medication group (P=0.0002). Pain returned to preoperative levels in eight (11.9%) cases in the no medication group. No recurrence of pain occurred in the DNG group (P=0.0061). The administration of DNG after resection of USLs with DIE significantly reduces the occurrence rate of endometriosis-related pain and endometriomas. Copyright © 2017 Elsevier B.V.

    Full Text Available BACKGROUND: Although numerous prognostic factors have been reported for colorectal cancer liver metastasis (CRLM, few studies have reported intraoperative blood loss (IBL effects on clinical outcome after CRLM resection. METHODS: We retrospectively evaluated the clinical and histopathological characteristics of 139 patients who underwent liver resection for CRLM. The IBL cutoff volume was calculated using receiver operating characteristic curves. Overall survival (OS and recurrence free survival (RFS were assessed using the Kaplan-Meier and Cox regression methods. RESULTS: All patients underwent curative resection. The median follow up period was 25.0 months (range, 2.1-88.8. Body mass index (BMI and CRLM number and tumor size were associated with increased IBL. BMI (P=0.01; 95% CI = 1.3-8.5 and IBL (P500mL were 71%, 33%, and 0%, respectively (P<0.01. RFS of patients within three IBL volumes at the end of the first year were 67%, 38%, and 18%, respectively (P<0.01. CONCLUSIONS: IBL during CRLM resection is an independent predictor of long term survival and tumor recurrence, and its prognostic value was confirmed by a dose-response relationship.

    Materials and Methods. From January 1, 2004 to December, 2007 a total of 20 patients with pancreatic malignancies were retrospectively evaluated who underwent pancreatic surgery with synchronous resection of hepatic, adjacent organ, or peritoneal metastases for proven UICC stage IV periampullary cancer of the pancreas. Perioperative as well as clinicopathological parameters were evaluated. Results. There were 20 patients (9 men, 11 women; mean age 58 years identified. The primary tumor was located in the pancreatic head (n=9, 45%, in pancreatic tail (n=9, 45%, and in the papilla Vateri (n=2, 10%. Metastases were located in the liver (n=14, 70%, peritoneum (n=5, 25%, and omentum majus (n=2, 10%. Lymphnode metastases were present in 16 patients (80%. All patients received resection of their tumors together with metastasectomy. Pylorus preserving duodenopancreatectomy was performed in 8 patients, distal pancreatectomy in 8, duodenopancreatectomy in 2, and total pancreatectomy in 2. Morbidity was 45% and there was no perioperative mortality. Median postoperative survival was 10.7 months (2.6–37.7 months which was not significantly different from a matched-pair group of patients who underwent pancreatic resection for UICC adenocarcinoma of the pancreas (median survival 15.6 months; P=.1. Conclusion. Pancreatic resection for M1 periampullary cancer of the pancreas can be performed safely in well-selected patients. However, indication for surgery has to be made on an individual basis.

    The gold standard of treatment for esthesioneuroblastoma consists of en bloc craniofacial resection with postoperative therapy dictated by histology and tumor extent. Numerous studies have shown fully endoscopic approaches to provide comparable survival and recurrence rates with decreased patient morbidity. Here we report the first multi-institutional series assessing smell outcomes of patients who underwent unilateral endoscopic resection of esthesioneuroblastoma with preservation of the contralateral olfactory bulb. A multi-institutional retrospective review was performed identifying patients who underwent endoscopic unilateral resection of esthesioneuroblastoma with preservation of 1 olfactory bulb between 2003 and 2015. After completion of postoperative radiation, patients were administered the University of Pennsylvania Smell Identification Test (UPSIT) to assess olfactory function. Fourteen patients (7 males, 7 females) were identified and tested for posttreatment olfactory function. All 14 patients received postoperative radiotherapy and 4 patients received additional chemotherapy. Mean follow-up time was 51.7 months. There was no disease recurrence. Six patients (43%) were found to have residual smell function with 2 patients (14%) having normal or mildly reduced smell function. Here we report the first multi-institutional series demonstrating smell preservation after unilateral endoscopic resection of esthesioneuroblastoma. In carefully selected patients, this approach can yield comparable survival with decreased patient morbidity. © 2016 ARS-AAOA, LLC.

    This report describes our experience using a modified anterior levator resection approach in myogenic ptosis patients and presents the results from a consecutive series of patients treated with this method. This was a retrospective case series study. Forty-one patients with moderate and severe myogenic ptosis were included. All patients underwent a modified anterior levator resection approach under local anesthesia. The procedure involved exposing Whitnall's ligament, dissecting and resecting the underlying levator muscle from Whitnall's ligament, and leaving the aponeurosis intact. All patients underwent pre- and postoperative photography, and final outcomes were assessed after a minimum of 6 months. Outcome measures included pre- and post-marginal reflex distance (MRD1), symmetry of height, contour, and complications. Forty-one patients undergoing 56 procedures were included. The mean age of the patients was 15 (13-18) years. The mean postoperative MRD1 was 3.45 mm. Thirty-four patients achieved their desired lid height and contour, and 7 patients had undercorrection, including 1 patient with 2 mm of asymmetry, with a final success rate of 83% (34/41 patients). Our modified anterior levator resection approach had a high success rate and is particularly suitable for patients with moderate and severe myogenic ptosis.

    Full Text Available Abstract Thymic large cell neuroendocrine carcinomas (LCNECs are very rare. We here describe a case in which the tumor could be completely resected. A 55-year-old male was admitted to our hospital for treatment of an anterior mediastinal tumor found at a regular health check-up. The patient underwent an extended thymectomy of an invasive thymoma of Masaoka's stage II that had been suspected preoperatively. The tumor was located in the right lobe of the thymus and was completely resected. Final pathological diagnosis of the surgical specimen was thymic LCNEC. The patient underwent adjuvant chemotherapy with irinotecan and cisplatin in accordance with the diagnosis of a lung LCNEC, and is alive without recurrence or metastasis 16 months after surgery.

    The resection of left-sided perisylvian brain lesions harbours the risk of postoperative language impairment. Therefore the individual patient's language distribution is investigated by intraoperative direct cortical stimulation (DCS) during awake surgery. Yet, not all patients qualify for awake surgery. Non-invasive language mapping by repetitive navigated transcranial magnetic stimulation (rTMS) has frequently shown a high correlation in comparison with the results of DCS language mapping in terms of language-negative brain regions. The present study analyses the extent of resection (EOR) and functional outcome of patients who underwent left-sided perisylvian resection of brain lesions based purely on rTMS language mapping. Four patients with left-sided perisylvian brain lesions (two gliomas WHO III, one glioblastoma, one cavernous angioma) underwent rTMS language mapping prior to surgery. Data from rTMS language mapping and rTMS-based diffusion tensor imaging fibre tracking (DTI-FT) were transferred to the intraoperative neuronavigation system. Preoperatively, 5 days after surgery (POD5), and 3 months after surgery (POM3) clinical follow-up examinations were performed. No patient suffered from a new surgery-related aphasia at POM3. Three patients underwent complete resection immediately, while one patient required a second rTMS-based resection some days later to achieve the final, complete resection. The present study shows for the first time the feasibility of successfully resecting language-eloquent brain lesions based purely on the results of negative language maps provided by rTMS language mapping and rTMS-based DTI-FT. In very select cases, this technique can provide a rescue strategy with an optimal functional outcome and EOR when awake surgery is not feasible.

    A craniotomy with direct cortical/subcortical stimulation either awake or under general anesthesia (GA) present 2 approaches for removing eloquent region tumors. With a reported higher prevalence of intraoperative seizures occurring during awake resections of perirolandic lesions, oftentimes, surgery under GA is chosen for these lesions. To evaluate a single-surgeon's experience with awake craniotomies (AC) vs surgery under GA for resecting perirolandic, eloquent, motor-region gliomas. Between 2005 and 2015, a retrospective analysis of 27 patients with perirolandic, eloquent, motor-area gliomas that underwent an AC were case-control matched with 31 patients who underwent surgery under GA for gliomas in the same location. All patients underwent direct brain stimulation with neuromonitoring and perioperative risk factors, extent of resection, complications, and discharge status were assessed. The postoperative Karnofsky Performance Score (KPS) was significantly lower for the GA patients at 81.1 compared to the AC patients at 93.3 ( P = .040). The extent of resection for GA patients was 79.6% while the AC patients had an 86.3% resection ( P = .136). There were significantly more 100% total resections in the AC patients 25.9% compared to the GA group (6.5%; P = .041). Patients in the GA group had a longer mean length of hospitalization of 7.9 days compared to the AC group at 4.2 days ( P = .049). We show that AC can be performed with more frequent total resections, better postoperative KPS, shorter hospitalizations, as well as similar perioperative complication rates compared to surgery under GA for perirolandic, eloquent motor-region glioma.

    To describe the use of disposable skin staples for intestinal resection and anastomosis in dogs and report associated dehiscence and mortality rates. Retrospective evaluation of medical records of dogs that underwent intestinal resection and anastomosis using disposable skin staples between 2000 and 2014. Data regarding patient signalment, indication for surgery, location of the resection and anastomosis, number of procedures performed, evidence of peritonitis at the time of surgery, surgeon qualifications, dehiscence, and mortality were obtained from the medical records. Mortality was defined as failure to survive beyond 10 days following resection and anastomosis. The overall mortality rate of patients undergoing intestinal resection and anastomosis was 12·7% (8/63). The most common indication for resection and anastomosis was neoplasia (20/63 [31·7%]), followed by foreign body removal (19/63 [30·2%]). The overall dehiscence rate was 4·8% (3/63). No difference in mortality associated with indication for surgery, whether multiple procedures were performed, surgeon qualifications, or evidence of peritonitis at the time of surgery was identified. In this retrospective study, the overall mortality and dehiscence rates using disposable skin staples were similar to previously reported outcomes following resection and anastomosis. © 2016 British Small Animal Veterinary Association.

    The long-term postoperative improvement of quality of life (QOL) and employment were investigated in patients undergoing resection of epileptogenic lesions detected by magnetic resonance (MR) imaging to identify the associated preoperative factors. Thirty of 47 patients who underwent lesionectomy between 1987-2001 replied to questionnaires. Patients with extratemporal resection outnumbered those with temporal lobe resection. The mean follow-up period was 12.4±3.7 years. An arbitrary score for quantitatively assessing QOL was assigned. The mean increases in QOL score points were significantly higher in the late childhood onset group than those in the early childhood onset group, and were also significantly higher in the temporal resection group and extratemporal resection of non-dysplastic cortical pathology group than in the extratemporal resection of dysplastic cortical pathology group. Postoperative QOL improvement and occupational status of patients depended on the completeness of seizure control. Resection of lesions detected by MR imaging in patients with intractable epilepsy resulted in effective long-term QOL improvement and postoperative occupational status. Favorable outcome was related mainly to the pathology of the epileptogenic lesions, whether the lesion site was temporal or extratemporal, and the completeness of seizure control. (author)

    Patients with pulmonary metastases from colorectal cancer (CRC) may benefit from aggressive surgical therapy. The objective of this study was to determine the role of major anatomic resection for pulmonary metastasectomy to improve survival when compared with limited pulmonary resection. Data of 522 patients (64.2% men, mean age 64.5 years) who underwent pulmonary resections with curative intent for CRC metastases over a 2-year period were reviewed. All patients were followed for a minimum of 3 years. Disease-specific survival (DSS) and disease-free survival (DFS) were assessed with the Kaplan-Meier method. Factors associated with DSS and DFS were analyzed using a Cox proportional hazards regression model. A total of 394 (75.6%) patients underwent wedge resection, 19 (3.6%) anatomic segmentectomy, 5 (0.9%) lesser resections not described, 100 (19.3%) lobectomy, and 4 (0.8%) pneumonectomy. Accordingly, 104 (19.9%) patients were treated with major anatomic resection and 418 (80.1%) with lesser resection. Operations were carried out with video-assisted thoracoscopic surgery (VATS) in 93 patients. The overall DSS and DFS were 55 and 28.3 months, respectively. Significant differences in DSS and DFS in favor of major resection versus lesser resection (DSS median not reached versus 52.2 months, P = 0.03; DFS median not reached versus 23.9 months, P < 0.001) were found. In the multivariate analysis, major resection appeared to be a protective factor in DSS [hazard ratio (HR) 0.6, 95% confidence interval (CI) 0.41-0.96, P = 0.031] and DFS (HR 0.5, 95% CI 0.36-0.75, P < 0.001). The surgical approach (VATS versus open surgical resection) had no effect on outcome. Major anatomic resection with lymphadenectomy for pulmonary metastasectomy can be considered in selected CRC patient with sufficient functional reserve to improve the DSS and DFS. Further prospective randomized studies are needed to confirm the present results. © The Author 2016. Published by Oxford University Press

    Full Text Available Abstract Background Adoptive cell therapy (ACT with tumor-infiltrating lymphocytes (TIL in patients with metastatic melanoma has been reported to have a 56% overall response rate with 20% complete responders. To increase the availability of this promising therapy in patients with advanced melanoma, a minimally invasive approach to procure tumor for TIL generation is warranted. Methods A feasibility study was performed to determine the safety and efficacy of laparoscopic liver resection to generate TIL for ACT. Retrospective review of a prospectively maintained database identified 22 patients with advanced melanoma and visceral metastasis (AJCC Stage M1c who underwent laparoscopic liver resection between 1 October 2005 and 31 July 2011. The indication for resection in all patients was to receive postoperative ACT with TIL. Results Twenty patients (91% underwent resection utilizing a closed laparoscopic technique, one required hand-assistance and another required conversion to open resection. Median intraoperative blood loss was 100 mL with most cases performed without a Pringle maneuver. Median hospital stay was 3 days. Three (14% patients experienced a complication from resection with no mortality. TIL were generated from 18 of 22 (82% patients. Twelve of 15 (80% TIL tested were found to have in vitro tumor reactivity. Eleven patients (50% received the intended ACT. Two patients were rendered no evidence of disease after surgical resection, with one undergoing delayed ACT with generated TIL after relapse. Objective tumor response was seen in 5 of 11 patients (45% who received TIL, with one patient experiencing an ongoing complete response (32+ months. Conclusions Laparoscopic liver resection can be performed with minimal morbidity and serve as an effective means to procure tumor to generate therapeutic TIL for ACT to patients with metastatic melanoma.

    To evaluate the surgical technique of "Kou mode of hepatic hilar anastomosis" in the treatment for type III or IV hilar cholangiocarcinoma. The clinical data of 89 patients with type III or IV hilar cholangiocarcinoma surgically treated in our department between Jan. 1990 and Jan. 2008 were retrospectively analyzed. Since January 2000, "Kou mode of hepatic hilar anastomosis" was performed for some patients with advanced hilar cholangiocarcinoma. The patients were divided into two groups: group A treated between 1990 and 1999, group B between 2000 and 2008. The rate of resection, therapeutic efficacy and complications in these two groups were compared, respectively. Of the 37 cases with hilar cholangiocarcinoma in group A, 4 were surgically treated (10.8%), with 1 (2.7%) radical resection and 3 (8.1%) palliative resection. Among the 52 cases with hilar cholangiocarcinoma in the group B, 35 (67.3%) received surgical resection, of them 15 (28.8%) underwent radical resection and 20 (38.5%) had palliative resection. Twenty-eight of these 35 cases underwent the "Kou mode of hepatic hilar anastomosis". The resection rate of advanced hilar cholangiocarcinoma in the group B was significantly higher than that in group A (P anastomosis" developed bile leakage to a varying degree and recovered after drainage and symptomatic treatment. The resection rate of type III or IV advanced hilar cholangiocarcinoma can be remarkably improved by using a novel alternative surgical technique called "Kou mode of hepatic hilar anastomosis". However, the long-term outcome still needs to be determined by close follow-up and further observation.

    Surgical treatment of giant pituitary adenomas is sometimes challenging. We present our surgical series of giant nonfunctioning adenomas to shed light on the limitations of effective and safe tumor resection. The preoperative tumor characteristics, surgical approaches, outcome, and histology of giant nonfunctioning adenoma (>40 mm) in 128 consecutive surgical patients are reviewed. The follow-up period ranged from 19 to 113 months (mean 62.2 months). A transsphenoidal approach was used in the treatment of 109 patients and a combined transsphenoidal transcranial approach in 19 patients. A total of 93 patients (72.7%) underwent total resection or subtotal resection apart from the cavernous sinus (CS). The degree of tumor resection, excluding the marked CS invasion, was lower in tumors that were larger (P = 0.0107), showed massive intracranial extension (P = 0.0352), and had an irregular configuration (P = 0.0016). Permanent surgical complications developed in 28 patients (22.0%). Long-term tumor control was achieved in all patients by single surgery, including 43 patients with adjuvant radiotherapy. Most tumors were histologically benign, with a low MIB-1 index (inherent factors that independently limit effective resection. These high-risk tumors require an individualized therapeutic strategy.

    Laparoscopic resection of transverse colon cancer at splenic flexure is technical demanding and its efficacy remains controversial. The aim of this study was to investigate its technical aspects such as pitfalls and overcoming them, and to demonstrate the short-term and oncologic long-term outcomes. To overcome the difficulty in laparoscopic resection of transverse colon cancer at splenic flexure, we recognized the following technical tips as essential. First of all, we have to precisely identify major vessels variations feeding tumor. Secondary, anatomical dissection of mesocolon through medial approach is indispensible. Third, safe takedown of splenic flexure to fully mobilization of left hemicolon is mandatory. This cohort study analyzed 95 patients with stage II (43) and III (52) underwent resection of transverse colon cancer at splenic flexure. 61 laparoscopic surgeries (LAC) and 34 conventional open surgeries (OC) from December 1996 to December 2009 were evaluated. Short-term and oncologic long-term outcomes were recorded. Operative time was longer in LAC. However, blood loss was less, recovery of bowel function and hospital stay were shorter in LAC. There was no conversion in LAC and no significant difference in the postoperative complications. Regarding oncologic long-term outcomes, there were no significant differences between OC and LAC. Laparoscopic resection of transverse colon cancer at splenic flexure resulted in acceptable short-term and oncologic long-term outcomes. Once technical tips acquired, laparoscopic resection of transverse colon cancer at splenic flexure could be feasible as minimally invasive surgery.

    Background: Open liver resection is the current standard of care for lesions in the right posterior liver section. The objective of this study was to determine the safety of robot-assisted liver resection for lesions located in segments 6 and 7 in comparison with open surgery. Methods: Demographics, comorbidities, clinicopathologic characteristics, surgical treatments, and outcomes from patients who underwent open and robot-assisted liver resection at 2 centers for lesions in the right posterior section between January 2007 and June 2012 were reviewed. A 1:3 matched analysis was performed by individually matching patients in the robotic cohort to patients in the open cohort on the basis of demographics, comorbidities, performance status, tumor stage, and location. Results: Matched patients undergoing robotic and open liver resections displayed no significant differences in postoperative outcomes as measured by blood loss, transfusion rate, hospital stay, overall complication rate (15.8% vs 13%), R0 negative margin rate, and mortality. Patients undergoing robotic liver surgery had significantly longer operative time (mean, 303 vs 233 minutes) and inflow occlusion time (mean, 75 vs 29 minutes) compared with their open counterparts. Conclusions: Robotic and open liver resections in the right posterior section display similar safety and feasibility. PMID:25516700

    The purpose of this study was to assess the capability of contrast-enhanced ultrasound (CEUS) to identify residual tumor mass during glioblastoma multiforme (GBM) surgery, to increase the extent of resection. The authors prospectively evaluated 10 patients who underwent surgery for GBM removal with navigated ultrasound guidance. Navigated B-mode and CEUS were performed prior to resection, during resection, and after complete tumor resection. Areas suspected for residual tumors on B-mode and CEUS studies were localized within the surgical field with navigated ultrasound and samples were sent separately for histopathological analysis to confirm tumor presence. In all cases tumor remnants were visualized as hyperechoic areas on B-mode, highlighted as CEUS-positive areas, and confirmed as tumoral areas on histopathological analysis. In 1 case only, CEUS partially failed to demonstrate residual tumor because the residual hyperechoic area was devascularized prior to ultrasound contrast agent injection. In all cases CEUS enhanced B-mode findings. As has already been shown in other neoplastic lesions in other organs, CEUS is extremely specific in the identification of residual tumor. The ability of CEUS to distinguish between tumor and artifacts or normal brain on B-mode is based on its capacity to show the vascularization degree and not the echogenicity of the tissues. Therefore, CEUS can play a decisive role in the process of maximizing GBM resection.

    To investigate whether the routine use of fibrin glue applied onto the hepatic resection area can diminish postoperative volume of bloody or biliary fluids drained via intraoperatively placed perihepatic tubes and can thus lower the complication rate. Two groups of consecutive patients with a comparable spectrum of recent hepatic resections were compared: (1) 13 patients who underwent application of fibrin glue immediately after resection of liver parenchyma; (2) 12 patients who did not. Volumes of postoperative drainage fluid were determined in 4-h intervals through 24 h indicating the intervention caused bloody and biliary segregation. Through the first 8 h postoperatively, there was a tendency of higher amounts of fluids in patients with no additional application of fibrin glue while through the following intervals, a significant increase of drainage volumes was documented in comparison with the first two 4-h intervals, e.g., after 12 h, 149.6 mL +/-110 mL vs 63.2 mL +/-78 mL. Using fibrin glue, postoperative fluid amounts were significantly lower through the postoperative observation period of 24 h (851 mL +/-715 mL vs 315 mL +/-305 mL). For hepatic resections, the use of fibrin glue appears to be advantageous in terms of a significant decrease of surgically associated segregation of blood or bile out of the resection area. This might result in a better outcome.

    We report the cases of two children who underwent CT, MR, MRA and angiography in the diagnosis of postoperative aneurysmal dilatation of the supraclinoid carotid arteries following surgical resection of craniopharyngioma. Craniopharyngiomas are relatively common lesions, accounting for 6-7 % of brain tumors in children. They are histologically benign, causing symptoms by their growth within the sella and suprasellar cistern with compression of adjacent structures, especially the pituitary gland, hypothalamus and optic nerves, chiasm, and tracts.

    Full Text Available Abstract Introduction Amyloidosis most often manifests as a systemic involvement of multiple tissues and organs, and an amyloidal deposit confined to the stomach is extremely rare. It is sometimes difficult to provide a definitive diagnosis of localized gastric amyloidosis by biopsy specimen and diagnosis of amyloidosis in some cases has been finalized only after surgical resection of the stomach. Case presentation A 76-year-old Japanese woman with epigastric discomfort underwent an esophagogastroduodenoscopy procedure. The esophagogastroduodenoscopy revealed gastric wall thickening, suggesting scirrhous gastric carcinoma, at the greater curvature from the upper to the lower part of the gastric corpus. A biopsy specimen revealed amyloid deposits in the submucosal layer with no malignant findings. We resected a representative portion of the lesion by endoscopic mucosal resection using the strip biopsy method to obtain sufficient tissue specimens, and then conducted a detailed histological evaluation of the samples. The resected specimens revealed deposition of amyloidal materials in the gastric mucosa and submucosa without any malignant findings. Congo red staining results were positive for amyloidal protein and exhibited green birefringence under polarized light. Congo red staining with prior potassium permanganate incubation confirmed the light chain (AL amyloid protein type. Based on these results, gastric malignancy, systemic amyloidosis and amyloid deposits induced by inflammatory disease were excluded and this lesion was consequently diagnosed as localized gastric amyloidosis. Our patient was an older woman and there were no findings relative to an increase in gastrointestinal symptoms or anemia, so no further treatment was performed. She continued to be in good condition without any finding of disease progression six years after verification of our diagnosis. Conclusions We report an unusual case of primary amyloidosis of the stomach

    To assess safety/efficacy of yttrium-90 radioembolization (Y90) in patients with recurrent hepatocellular carcinoma (HCC) following curative surgical resection. With IRB approval, we searched our prospectively acquired database for patients that were treated with Y90 for recurrent disease following resection. Baseline characteristics and bilirubin toxicities following Y90 were evaluated. Intention-to-treat overall survival (OS) and time-to-progression (TTP) from Y90 were assessed. Forty-one patients met study inclusion criteria. Twenty-six (63%) patients had undergone minor (≤3 hepatic segments) resection while 15 (37%) patients underwent major (>3 hepatic segments) resections. Two patients (5%) had biliary-enteric anastomoses created during surgical resection. The median time from HCC resection to the first radioembolization was 17 months (95% CI: 13-37). The median number of Y90 treatment sessions was 1 (range: 1-5). Ten patients received (entire remnant) lobar Y90 treatment while 31 patients received selective (≤2 hepatic segments) treatment. Grades 1/2/3/4 bilirubin toxicity were seen in nine (22%), four (10%), four (10%), and zero (0%) patients following Y90. No differences in bilirubin toxicities were identified when comparing lobar with selective approaches (P = 0.20). No post-Y90 infectious complications were identified. Median TTP and OS were 11.3 (CI: 6.5-15.5) and 22.1 months (CI: 10.3-31.3), respectively. Radioembolization is a safe and effective method for treating recurrent HCC following surgical resection, with prolonged TTP and promising survival outcomes. (orig.)

    The prognosis and survival of patients with advanced gastric cancer is poor. Although completeness of resection (R0) is one of the most important factors affecting survival, multivisceral resection (MVR) for locally advanced (clinical T4b, cT4b) gastric cancer remains controversial. The aim of this study was to evaluate the factors affecting prognosis and survival after MVR in patients with cT4b gastric cancer. Between 2005 and 2015, we retrospectively reviewed the medical records of 103 patients who underwent MVR for cT4b gastric cancer with suspected direct invasion to adjacent organs. Patient characteristics, related complications, long-term survival, and prognostic factors of cT4b gastric cancer were analyzed. Postoperative mortality and morbidity rates of patients after MVR were 1.0 and 37.9%, respectively. R0 resection was achieved in 82.5% patients, all of whom had a significantly improved survival rate. Overall survival rates at 1 and 3 years were 78.3 and 47.7% for R0 resection and 46.6 and 14.3% for R1 resection, respectively (R0 vs. R1, P < 0.002). Multivariate analysis revealed that completeness of resection (R0) was an independent prognostic factor associated with longer survival. In patients with cT4b gastric cancer, gastrectomy with MVR to achieve an R0 resection can be performed with acceptable postoperative morbidity and mortality rates and can have a positive impact on long-term survival.

    Surgery is the treatment of choice in patients with colorectal liver metastases. However, only 10% to 20% of these cases are resectable. The use of neoadjuvant chemotherapy may allow surgery in patients with tumors initially considered unresectable. The aim of this study was to compare the results of liver resection due to colorectal liver metastases in patients with and without neoadjuvant chemotherapy. We studied 105 patients who underwent surgery for liver metastases from colorectal cancer. The patients were divided into two groups according to treatment: surgery in patients with initially resectable tumors (group 1) and neoadjuvant chemotherapy plus surgery (group 2) in patients with initially irresectable tumors, who were considered for surgery after response to chemotherapy. Age, sex, origin of primary tumor, time of presentation, number, maximum size and location of metastases, CEA, resection margin, postoperative morbidity and mortality, length of hospital stay, recurrence rate, survival and disease-free survival were compared between the 2 groups of patients. When group 1 was compared with group 2, statistically significant differences were observed in synchronicity (30.8% vs 77.4%), bilobarity (13.5% vs 58.5%), number and size of metastases (1 vs 3 nodules and 4 cm vs 2 cm), resectability rate (96.1% vs 81.1%), disease-free interval (25 vs 11 months) and long-term survival at 1, 3 and 5 years (93%, 67% and 36% vs 78%, 26% and 12%). However, no statistically significant differences were found in postoperative morbidity and mortality (28.8% and 0% in group 1 and 22.6% and 1.8% in group 2, respectively). Neoadjuvant chemotherapy was not associated with greater postoperative morbidity and mortality after resection of colorectal liver metastases, but long-term survival was lower in the group of patients receiving this treatment modality than in those with tumors initially considered resectable.

    Despite recent advances in the treatment of advanced gastric carcinomas, no satisfactory outcomes are available because of micrometastases and free-floating carcinoma cells already existing in the peritoneal cavity. From 1990, we started using intraperitoneal hyperthermo-chemo-perfusion (IHCP) to prevent and to treat peritoneal metastasis after surgical resection of stomach cancer. We analyzed 103 serosa-invasive gastric carcinoma patients who underwent surgical resection between 1990 and 1995. Fifty-two patients who received surgery plus IHCP were compared with 51 patients who underwent surgery only, as controls. IHCP was administered for 2 h with an automatic IHCP device (closed-circuit system) just after surgical resection, with the patient under hypothermic general anesthesia (32.4 degrees C-34.0 degrees C). As perfusate, we used 1.5% peritoneal dialysis solution mixed with 10 micrograms/ml of mitomycin-C (MMC), warmed at an inflow temperature of over 44 degrees C. The overall 5-year survival rate (5-YSR) of the 103 patients was 29.97%. The 5-YSR was higher in the IHCP group than in the control group, at 32.7% and 27.1%, respectively, but this difference was not significant. However, in the 65 serosa-invasive gastric carcinoma patients (excluding those in stage IV) the 5-YSR was significantly higher (P = 0.0379) in the IHCP group than in the control group, at 58.6% and 44.4%, respectively. On multivariate analysis of all 103 patients, depth of tumor invasion and lymph node metastasis were significant factors for survival, whereas significant factors on univariate analysis, such as combined operation, distant metastasis, and peritoneal metastasis, were not significant. The most common recurrence patterns were loco-regional in the IHCP group and peritoneal in the control group. Complete cytoreductive surgery plus IHCP is effective to prevent and to treat peritoneal metastasis, and it should lead to long-term survival for serosa-invasive gastric carcinoma patients

    Pancreatic cancer is the fourth leading cause of cancer death in the United States. While surgical resection remains the only curative option, more than 80% of patients present with unresectable disease. Unfortunately, even among those who undergo resection, the reported median survival is 15-23 mo, with a 5-year survival of approximately 20%. Disappointingly, over the past several decades, despite improvements in diagnostic imaging, surgical technique and chemotherapeutic options, only modest improvements in survival have been realized. Nevertheless, it remains clear that surgical resection is a prerequisite for achieving long-term survival and cure. There is now emerging consensus that a subgroup of patients, previously considered poor candidates for resection because of the relationship of their primary tumor to surrounding vasculature, may benefit from resection, particularly when preceded by neoadjuvant therapy. This stage of disease, termed borderline resectable pancreatic cancer, has become of increasing interest and is now the focus of a multi-institutional clinical trial. Here we outline the history, progress, current treatment recommendations, and future directions for research in borderline resectable pancreatic cancer. PMID:25152577

    Pancreatic cancer is the third most common cause of cancer deaths in the United States. Surgical resection with negative margins still constitutes the cornerstone of potentially curative therapy, but is possible only in 15-20% of patients at the time of initial diagnosis. Accumulating evidence suggests that the neoadjuvant approach may improve R0 resection rate in localized resectable and borderline resectable diseases, and potentially downstage locally advanced disease to achieve surgical resection, though the impact on survival is to be determined. Despite advancements in the last decade in developing effective combinational chemo-radio therapeutic options, preoperative treatment strategies, and better peri-operative care, pancreatic cancer continues to carry a dismal prognosis in the majority. Prodigious efforts are currently being made in optimizing the neoadjuvant therapy with a better toxicity profile, developing novel agents, imaging techniques, and identification of biomarkers for the disease. Advancement in our understanding of the tumor microenvironment and molecular pathology is urgently needed to facilitate the development of novel targeted and immunotherapies for this setting. In this review, we detail the current literature on contemporary management of resectable, borderline resectable and locally advanced pancreatic cancer with a focus on future directions in the field.

    Augmented Reality (AR) guidance is a technology that allows a surgeon to see sub-surface structures, by overlaying pre-operative imaging data on a live laparoscopic video. Our objectives were to evaluate a state-of-the-art AR guidance system in a tumor surgical resection model, comparing the accuracy of the resection with and without the system. Our system has three phases. Phase 1: using the MRI images, the kidney's and pseudotumor's surfaces are segmented to construct a 3D model. Phase 2: the intra-operative 3D model of the kidney is computed. Phase 3: the pre-operative and intra-operative models are registered, and the laparoscopic view is augmented with the pre-operative data. We performed a prospective experimental study on ex vivo porcine kidneys. Alginate was injected into the parenchyma to create pseudotumors measuring 4-10 mm. The kidneys were then analyzed by MRI. Next, the kidneys were placed into pelvictrainers, and the pseudotumors were laparoscopically resected. The AR guidance system allows the surgeon to see tumors and margins using classical laparoscopic instruments, and a classical screen. The resection margins were measured microscopically to evaluate the accuracy of resection. Ninety tumors were segmented: 28 were used to optimize the AR software, and 62 were used to randomly compare surgical resection: 29 tumors were resected using AR and 33 without AR. The analysis of our pathological results showed 4 failures (tumor with positive margins) (13.8%) in the AR group, and 10 (30.3%) in the Non-AR group. There was no complete miss in the AR group, while there were 4 complete misses in the non-AR group. In total, 14 (42.4%) tumors were completely missed or had a positive margin in the non-AR group. Our AR system enhances the accuracy of surgical resection, particularly for small tumors. Crucial information such as resection margins and vascularization could also be displayed.

    Background: Recurrence of thymomas even after complete resection is common, but the relapse patterns remain controversial. This study aimed to define the patterns and predictors of relapse after complete resection of thymoma. Methods: A single-institution retrospective study was performed with 331 patients who underwent radical resection of thymoma between 1991 and 2012. Results: After a median follow-up of 59 months, the recurrence rate was 6.9% (23/331). Relapse occurred in 23 patients with the pleura (14) and tumor bed (6) as the most common sites of recurrence. According to the definitions of the International Thymic Malignancy Interest Group, 10 (43.5%) patients had local relapse, 15 (65.2%) had regional relapse, 10 (43.5%) had distant relapse. The difference in survival following relapse between lung and regional relapse was statistically significant (P = 0.027) but that between lung and distant relapse was not (P = 0.808). The recurrence rates correlated with the initial Masaoka stage. Further, recurrence also correlated with World Health Organization (WHO) tumor type. The recurrence-free survival rates in patients with tumor size ⩾8 cm were worse than those of patients with tumor size <8 cm (P = 0.007). Tumor size was also correlated with stage (r = 0.110). As tumor becomes larger, the stage is more advanced (P = 0.023). Multivariate analysis showed that Masaoka stage (P = 0.005), tumor size (P = 0.033), and WHO histological type (P = 0.046) were predictive factors of relapse. Conclusion: Regional recurrence is the most common relapse pattern but local and distant relapse are also common. Advanced Masaoka stage, larger tumor size, and type B3 are risk factors of recurrence. Lung relapse should be considered distant relapse. Further, tumor size was correlated with Masaoka stage and therefore should be considered in the staging system

    This randomized controlled trial (RCT) was performed to test the hypothesis that adverse event rates following primary anastomosis (PRA) are not inferior to those following nonrestorative colon resection for perforated diverticulitis with peritonitis. Patients admitted for perforated diverticulitis with peritonitis were randomly assigned to PRA (left colon resection with PRA and loop ileostomy) or nonrestorative colon resection (left colon resection with end colostomy). The endpoint was adverse events defined as mortality and morbidity following PRA or nonrestorative colon resection and stoma reversal. The estimated sample size was 300 patients in each study arm (alpha 0.10; 90% power). During a 9-year period, 90 patients were randomly assigned to undergo PRA or nonrestorative colon resection in 14 centres in eight countries. Thirty-four PRA patients were comparable to 56 nonrestorative colon resection patients for age (P = 0.481), gender (P = 0.190), APACHE III (P = 0.281), Hinchey stage III vs IV (P = 0.394) and Mannheim Peritonitis Index (P = 0.145). There were no differences in operating time (P = 0.231), surgeries performed at night (P = 0.083), open vs laparoscopic approach (P = 0.419) and litres of peritoneal irrigation (P = 0.096). There was no significant difference in mortality (2.9 vs 10.7%; P = 0.247) and morbidity (35.3 vs 46.4%; P = 0.38) following PRA or nonrestorative colon resection. After a similar lag time (P = 0.43), 64.7% of PRA patients and 60% of nonrestorative colon resection patients underwent stoma reversal (P = 0.659). Adverse event rates following stoma reversal differed significantly after PRA and reversal of nonrestorative resection (4.5 vs 23.5%; P = 0.0589). No conclusions may be drawn on preference of one treatment over another from this RCT because it was prematurely terminated following accrual of 15% of its sample size. © 2012 The Authors.

    Whether preoperative chemoradiotherapy (CRT) is better than postoperative CRT in oncologic outcome and toxicity is contentious in prospective randomized clinical trials. We systematically analyze and compare the treatment result, toxicity, and sphincter preservation rate between preoperative CRT and postoperative CRT in stage II–III rectal cancer. We searched Medline, Embase, and Cochrane Library from 1990 to 2014 for relevant trials. Only phase III randomized studies performing CRT and curative surgery were selected and the data were extracted. Meta-analysis was used to pool oncologic outcome and toxicity data across studies. Three randomized phase III trials were finally identified. The meta-analysis results showed significantly lower 5-year locoregional recurrence rate in the preoperative-CRT group than in the postoperative-CRT group (hazard ratio, 0.59; 95% confidence interval, 0.41–0.84; p = 0.004). The 5-year distant recurrence rate (p = 0.55), relapse-free survival (p = 0.14), and overall survival (p = 0.22) showed no significant difference between two groups. Acute toxicity was significantly lower in the preoperativeCRT group than in the postoperative-CRT group (p < 0.001). However, there was no significant difference between two groups in perioperative and chronic complications (p = 0.53). The sphincter-saving rate was not significantly different between two groups (p = 0.24). The conversion rate from abdominoperineal resection to low anterior resection in low rectal cancer was significantly higher in the preoperative-CRT group than in the postoperative-CRT group (p < 0.001). As compared to postoperative CRT, preoperative CRT improves only locoregional control, not distant control and survival, with similar chronic toxicity and sphincter preservation rate in rectal cancer patients.

    Conventional endoscopic resection techniques such as endoscopic mucosal resection or endoscopic submucosal dissection are powerful tools for treatment of gastrointestinal neoplasms. However, those techniques are restricted to superficial layers of the gastrointestinal wall. Endoscopic full-thickness resection (EFTR) is an evolving technique, which is just about to enter clinical routine. It is not only a powerful tool for diagnostic tissue acquisition but also has the potential to spare surgical therapy in selected patients. This review will give an overview about current EFTR techniques and devices.

    The aim of this study is to assess the short-term outcome of intraoperative colonic irrigation and primary anastomosis and to suggest the usefulness of the procedure when a preoperative mechanical bowel preparation is inappropriate. This retrospective study included 38 consecutive patients (19 male patients) who underwent intraoperative colonic irrigation and primary anastomosis for left colon disease between January 2010 and December 2016. The medical records of the patients were reviewed to evaluate the patients' characteristics, operative data, and postoperative short-term outcomes. Twenty-nine patients had colorectal cancer, 7 patients had perforated diverticulitis, and the remaining 2 patients included 1 with sigmoid volvulus and 1 with a perforated colon due to focal colonic ischemia. A diverting loop ileostomy was created in 4 patients who underwent a low anterior resection. Complications occurred in 15 patients (39.5%), and the majority was superficial surgical site infections (18.4%). Anastomotic leakage occurred in one patient (2.6%) who underwent an anterior resection due sigmoid colon cancer with obstruction. No significant difference in overall postoperative complications and superficial surgical site infections between patients with obstruction and those with peritonitis were noted. No mortality occurred during the first 30 postoperative days. The median hospital stay after surgery was 15 days (range, 8-39 days). Intraoperative colonic irrigation and primary anastomosis seem safe and feasible in selected patients. This procedure may reduce the burden of colostomy in patients requiring a left colon resection with an inappropriate preoperative mechanical bowel preparation.

    The relationship of scope of practice (predominantly adult, versus predominantly pediatric) with the outcomes of brain tumor surgery in children remains uncertain. We investigated the association of practice focus with the outcomes of neurosurgical oncology operations in pediatric patients. We performed a cohort study of all pediatric patients (younger than 18 years old) who underwent craniotomies for tumor resections from 2009 to 2013 and were registered in the Statewide Planning and Research Cooperative System (SPARCS) database. In order to control for confounding, we used propensity score conditioning with mixed effects analysis to account for clustering at the hospital level. During the study period, there were 770 pediatric patients who underwent craniotomy for tumor resection and met the inclusion criteria. Of these, 370 (48.1%) underwent treatment by providers with predominantly adult practices and 400 (51.9%) by physicians who operated predominantly on children. Mixed-effects multivariable regression analysis demonstrated lack of association of predominantly adult practice with inpatient mortality (OR, 1.12; 95% CI, 0.48-2.58), and discharge to a facility (OR, 1.25; 95% CI, 0.77-2.03). These associations persisted in propensity-adjusted models. In a cohort of pediatric patients undergoing craniotomy for tumor resection from a comprehensive all-payer database, we did not demonstrate a difference in mortality, and discharge to a facility between providers with predominantly adult and predominantly pediatric practices.

    Full Text Available Pheochromocytoma (PCC is a rare cause of hypertension during pregnancy [1:54000 pregnancies]. Fetomaternal morbidity and mortality is about 58% if the diagnosis is missed. Administration of anesthesia to patients with PCC is challenging. Associated pregnancy adds to the problems. This is a case report of a patient having PCC diagnosed at 26 weeks of gestation. With medical management pregnancy was continued till 34 weeks. She was posted for cesarean section and resection of PCC. Patient underwent surgery lasting for 7 h due to inferior vena cava tear and had stormy intra as well as postoperative course. Mother and baby had uneventful recovery due to continuous invasive monitoring and a good teamwork, despite limited anesthetic resources.

    Para-aortic lymph node (PALN) metastasis from colorectal cancer is rare and often not suitable for surgery. However, in selected patients, radical resection may bring about longer survival. The aim of this study was to evaluate long-term outcomes of resection of left-sided colon or rectal cancer with simultaneous PALN metastasis. The study included 2122 patients with left-sided colon or rectal cancer (30 patients with and 2092 patients without PALN metastasis) who underwent resection with curative intent between 2002 and 2013. Clinicopathological characteristics, long-term outcomes of resection, and factors related to poor postoperative survival in patients with PALN metastasis were investigated. Of a total of 2122 total patients, 16 of 50 patients (32.0%) with lymph node metastasis at the root of the inferior mesenteric artery had PALN metastasis. The 5-year overall survival rates for 18 patients who underwent R0 resection and 12 patients who did not were 29.1 and 10.4%, respectively (p = 0.017). Factors associated with poor postoperative survival among patients who underwent R0 resection were presence of conversion therapy, lack of adjuvant chemotherapy, carcinoembryonic antigen >20 ng/mL, and lateral lymph node metastasis in rectal cancer patients. The 5-year recurrence-free survival rate was 14.8%. Although recurrence was frequent, R0 resection for left-sided colon or rectal cancer with PALN metastasis was associated with longer survival than R1/R2 resection. Furthermore, the 5-year overall survival rate in the R0 group was relatively favorable for stage IV. Therefore, R0 resection may prolong survival compared with chemotherapy alone in selected patients.

    To determine the effect on eyelid elevation of excising excess skin, orbicularis oculi muscle, and herniated orbital fat and reconstructing the upper eyelid crease (blepharoplasty) concomitant with a Müller muscle-conjunctival resection. The charts of 202 patients who had undergone Müller muscle-conjunctival resection during an 8-year interval were reviewed. Three hundred forty-five eyelids were divided into two groups. Group 1 (n = 162) underwent a Müller muscle-conjunctival resection only, and group 2 (n = 183) had this procedure combined with excision of skin, orbicularis muscle, and herniated orbital fat with upper eyelid crease reconstruction. Each group was divided into three subgroups based on the amount of Müller muscle-conjunctival resection. Subgroup A had resection less than 7.75 mm; subgroup B, resection of 7.75 to 8.75 mm; and subgroup C, resection greater than 8.75 mm. The change in margin reflex distance-1 (MRD1) measurements of the upper eyelid levels (postoperative MRD1 minus preoperative MRD1) were calculated and compared between groups. The mean (+/- standard deviation) change in MRD1 was, respectively, 2.3 +/-1.0 mm and 1.9+/-1.0 mm for groups 1A and 2A; 3.1+/-1.3 mm and 2.1+/-1.2 mm for groups 1B and 2B; and 3.4+/-1.2 mm and 2.8+/-1.3 for groups 1C and 2C. Blepharoplasty performed concomitant with a Müller muscle-conjunctival resection reduced the anticipated postoperative eyelid elevation by as much as 1 mm. Surgeons who perform these procedures together should be aware that a larger Müller muscle-conjunctival resection may be required to obtain the desired increase in eyelid height postoperatively.

    Endoscopic full-thickness resection (EFTR) in the lower gastrointestinal tract may be a valuable therapeutic and diagnostic approach for a variety of indications. Although feasibility of EFTR has been demonstrated, there is a lack of safe and effective endoscopic devices for routine use. The aim of this study was to investigate the efficacy and safety of a novel over-the-scope device for colorectal EFTR. Between July 2012 and July 2014, 25 patients underwent EFTR at two tertiary referral centers. All resections were performed using the full-thickness resection device (FTRD; Ovesco Endoscopy, Tübingen, Germany). Data were collected retrospectively. Indications for EFTR were: recurrent or incompletely resected adenoma with nonlifting sign (n = 11), untreated adenoma and nonlifting sign (n = 2), adenoma involving the appendix (n = 5), flat adenoma in a patient with coagulopathy (n = 1), diagnostic re-resection after incomplete resection of a T1 carcinoma (n = 2), adenoma involving a diverticulum (n = 1), submucosal tumor (n = 2), and diagnostic resection in a patient with suspected Hirschsprung's disease (n = 1). In one patient, the lesion could not be reached because of a sigmoid stenosis. In the other patients, resection of the lesion was macroscopically complete and en bloc in 20/24 patients (83.3 %). The mean diameter of the resection specimen was 24 mm (range 12 - 40 mm). The R0 resection rate was 75.0 % (18/24), and full-thickness resection was histologically confirmed in 87.5 %. No perforations or major bleeding were observed during or after resection. Two patients developed postpolypectomy syndrome, which was managed with antibiotic therapy. Full-thickness resection in the lower gastrointestinal tract with the novel FTRD was feasible and effective. Prospective studies are needed to further evaluate the device and technique. © Georg Thieme Verlag KG Stuttgart · New York.

    Interstitial pregnancy is a dangerous and uncommon variation of ectopic pregnancy occurring in the interstitial part of the fallopian tube and extending beyond the muscular layer of the uterus. This ectopic pregnancy-related mortality rate has been reported to be as high as 2%-2,5% due to complications involving bleeding and hypervascularity. No prospective clinical trials have evaluated available treatment options for interstitial ectopic pregnancy due to its low incidence; there is thus no consensus regarding optimal treatment. Surgical treatment can be divided into conservative approaches, such as cornuectomy or cornuostomy, and radical approaches such as hysterectomy. However, intraoperative hemorrhage is an ever-present risk, regardless of the surgical approach adopted. This paper presents a case involving a patient who underwent laparoscopic resection of an interstitial twin ectopic pregnancy; a barbed suture pursestring was used which proved useful during the surgical technique and improved hemostasia.

    Full Text Available Abstract Objective: The present study investigated effect of using pump on postoperative pleural effusion in patients who underwent coronary artery bypass grafting. Methods: A total of 256 patients who underwent isolated coronary artery bypass grafting surgery in the Cardiovascular Surgery clinic were enrolled in the study. Jostra-Cobe (Model 043213 105, VLC 865, Sweden heart-lung machine was used in on-pump coronary artery bypass grafting. Off-pump coronary artery bypass grafting was performed using Octopus and Starfish. Proximal anastomoses to the aorta in both on-pump and off-pump techniques were performed by side clamps. The patients were discharged from the hospital between postoperative day 6 and day 11. Results: The incidence of postoperative right pleural effusion and bilateral pleural effusion was found to be higher as a count in Group 1 (on-pump as compared to Group 2 (off-pump. But the difference was not statistically significant [P>0.05 for right pleural effusion (P=0.893, P>0.05 for bilateral pleural effusion (P=0.780]. Left pleural effusion was encountered to be lower in Group 2 (off-pump. The difference was found to be statistically significant (P<0.05, P=0.006. Conclusion: Under the light of these results, it can be said that left pleural effusion is less prevalent in the patients that underwent off-pump coronary artery bypass grafting when compared to the patients that underwent on-pump coronary artery bypass grafting.

    Full Text Available BACKGROUND: Clinical experiences of adults who underwent surgery for esophageal atresia at birth is limited. There is some evidence that suggests considerable long-term morbidity, partly because of dysphagia, which has been reported in up to 85% of adult patients who undergo surgery for esophageal atresia. The authors hypothesized that dysphagia in this population is caused by dysmotility and/or anatomical anomalies.

    The classifications of acute uncomplicated diverticulitis and complicated diverticulitis have served us well for many years. However, in recent years, we have noted the prevalence of variations of uncomplicated diverticulitis, which have not precisely fit under the classification of 'acute resolving uncomplicated diverticulitis', which manifests itself with the typical left lower quadrant pain, fever, diarrhea, elevated white blood count, and CT findings, such as stranding, and which resolves fairly promptly and completely on oral antibiotic therapy. For these other variations, we would suggest we use the term chronic diverticulitis, as a subset of uncomplicated diverticulitis, meaning there is no abscess, stricture, or fistula, but the episode does not respond to the usual antibiotic treatment, and there is a rebound symptomatology once the treatment has stopped, or there is continuing subliminal inflammation that continues, typically, for several weeks after the initial episode without complete resolution. This variation could also be termed 'smoldering' diverticulitis. A second variation of uncomplicated diverticulitis should be termed atypical diverticulitis, since this variant does not manifest all of the usual components of acute diverticulitis, particularly an absence of fever, and even white blood count elevation, and there may be a lack of diagnostic evidence of acute diverticulitis. This diagnosis must be compared with diarrhea-predominant irritable bowel syndrome, and it is sometimes very difficult to distinguish between these two entities. The character of the pain in irritable bowel syndrome is typically cramping intermittently, compared with the more constant pain in smoldering diverticulitis. In our study by Horgan, McConnell, Wolff and coworkers, 5% of 930 patients who underwent sigmoid resection fit into this category of atypical uncomplicated diverticulitis. These 47 patients all had diverticulosis, and 76% that had surgery had evidence of acute

    Full Text Available Introduction: There is a steady increase in the number of elderly patients with severe cardiovascular diseases who require a surgical procedure to recover some quality of life that allows them a socially meaningful existence, despite the risks.Objectives: To analyze the behavior of elderly patients who underwent cardiac surgery with cardiopulmonary bypass.Method: A descriptive, retrospective, cross-sectional study was conducted with patients over 65 years of age who underwent surgery at the Cardiocentro Ernesto Che Guevara, in Santa Clara, from January 2013 to March 2014.Results: In the study, 73.1% of patients were men; and there was a predominance of subjects between 65 and 70 years of age, accounting for 67.3%. Coronary artery bypass graft was the most prevalent type of surgery and had the longest cardiopulmonary bypass times. Hypertension was present in 98.1% of patients. The most frequent postoperative complications were renal dysfunction and severe low cardiac output, with 44.2% and 34.6% respectively.Conclusions: There was a predominance of men, the age group of 65 to 70 years, hypertension, and patients who underwent coronary artery bypass graft with prolonged cardiopulmonary bypass. Renal dysfunction was the most frequent complication.

    Full Text Available BACKGROUND: Atherosclerosis is the main cause of peripheral artery occlusive disease (PAOD of the lower limbs. Patients with PAOD often also have obstructive atherosclerosis in other arterial sites, mainly the coronary arteries. This means that patients who undergo infrainguinal bypass to treat critical ischemia have a higher risk of AMI. There are, however, few reports in the literature that have assessed this risk properly. OBJECTIVE: The aim of this study was to determine the incidence of acute myocardial infarction in patients who underwent infrainguinal bypass to treat critical ischemia of the lower limbs caused by PAOD. MATERIAL AND METHODS: A total of 64 patients who underwent 82 infrainguinal bypass operations, from February 2011 to July 2012 were studied. All patients had electrocardiograms and troponin I blood assays during the postoperative period (within 72 hours. RESULTS: There were abnormal ECG findings and elevated blood troponin I levels suggestive of AMI in five (6% of the 82 operations performed. All five had conventional surgery. The incidence of AMI as a proportion of the 52 conventional surgery cases was 9.6%. Two patients died. CONCLUSION: There was a 6% AMI incidence among patients who underwent infrainguinal bypass due to PAOD. Considering only cases operated using conventional surgery, the incidence of AMI was 9.6%.

    Our objective was to assess the ability of dual-phase helical CT (DHCT) to predict resectability of carcinoma of gallbladder (CaGB). Thirty-two consecutive patients suspected of having CaGB on clinical examination and sonography presented to our centre over 10-month period. All these 32 patients underwent DHCT. Fifteen patients were considered inoperable and 2 had xanthogranulomatous cholecystitis. The remaining 15 patients (10 women, 5 men; age range 33-72 years) underwent surgery and had histopathological confirmation of CaGB and were included in the study based on the following criteria: presence of mass in gallbladder fossa on sonography and DHCT, and confirmation at surgery and histopathological examination. Axial reconstructions of 2 mm were obtained (collimation 3 mm, table speed 4.5 mm/s) for arterial (scan delay 20 s) and venous (scan delay 60 s) phases on a helical scanner. The criteria used for unresectability were: distant metastasis (liver, peritoneum, lymph nodes), extensive local contiguous organ spread, involvement of secondary biliary confluence of both lobes of liver, tumoral invasion of main portal vein, or proper hepatic artery or simultaneous invasion of one side hepatic artery and the other side portal vein. The CT findings related to unresectability were correlated with surgical findings. On the basis of CT findings, 10 patients were unresectable and 5 were resectable. Of the 10 patients considered unresectable, 9 had tumours that were unresectable at surgery (sensitivity 100%, positive predictive value 90%). Five patients had more than one reason and 4 had one reason alone for being unresectable (lymph nodes, n=2; hepatic metastasis, n=1; and vascular invasion, n=1). All 5 patients considered resectable based on CT findings had resectable tumours at surgery (negative predictive value 100%). The overall accuracy of CT was 93.3%. Dual-phase helical CT comprehensively evaluates CaGB and may be a useful tool in preoperative staging of this

    To evaluate the value of physical examination as a monitoring tool during subcortical resection in awake craniotomy patients and surgical outcomes. Authors reviewed medical records of patients underwent awake craniotomy with continuous physical examination for pathology adjacent to the eloquent area. Between January 2006 and August 2015, there were 37 patients underwent awake craniotomy with continuous physical examination. Pathology was located in the left cerebral hemisphere in 28 patients (75.7%). Thirty patients (81.1%) had neuroepithelial tumors. Degree of resections were defined as total, subtotal, and partial in 16 (43.2%), 11 (29.7%) and 10 (27.0%) patients, respectively. Median follow up duration was 14 months. The reasons for termination of subcortical resection were divided into 3 groups as follows: 1) by anatomical landmark with the aid of neuronavigation in 20 patients (54%), 2) by reaching subcortical stimulation threshold in 8 patients (21.6%), and 3) by abnormal physical examination in 9 patients (24.3%). Among these 3 groups, there were statistically significant differences in the intraoperative (p=0.002) and early postoperative neurological deficit (p=0.005) with the lowest deficit in neuronavigation group. However, there were no differences in neurological outcome at later follow up (3-months p=0.103; 6-months p=0.285). There were no differences in the degree of resection among the groups. Continuous physical examination has shown to be of value as an additional layer of monitoring of subcortical white matter during resection and combining several methods may help increase the efficacy of mapping and monitoring of subcortical functions.

    Sessile serrated polyps (SSPs) are associated with higher rates of incomplete resection compared to conventional adenomas after traditional snare polypectomy. Outcomes after endoscopic mucosal resection (EMR) are less established. The aim of this study was to evaluate the rate of residual neoplasia at surveillance colonoscopy for SSPs compared to conventional adenomas ≥ 10 mm after en bloc EMR. Retrospective cohort study of consecutive patients referred for EMR of a colonic lesion ≥ 10 mm from 2005 to 2013. Data on procedures, histopathology, and surveillance colonoscopies were recorded. The primary outcome was rate of macroscopically evident residual neoplasia at surveillance colonoscopy for SSPs compared to adenomas. Secondary outcomes included rate of neoplasia at the resection margin. 283 consecutive patients with 293 polyps underwent en bloc EMR including 101 SSPs and 192 adenomas. Pathology commented on the lateral resection margins of the specimen in 235 cases (80%). Of these, neoplasia was noted at the resection margin in 29/64 SSPs (45.3%) compared to 65/171 adenomas (38.0%; P = .37). Surveillance data were available for 153 index lesions with a median interval of 13 months (interquartile range, 10.75-23.25 months). Ten resection sites (6.5%) were found to have residual neoplasia, including 2/52 SSPs (3.8%) and 8/101 adenomas (7.9%; P = .50). Of the cases with surveillance data 128/153 (84%) commented on the lateral margin of the resection specimen. Residual neoplasia was noted in 3/68 lesions (4.4%) with negative margins compared to 5/60 lesions (8.3%) with positive margins (P = .47). En bloc EMR for colonic lesions ≥ 10 mm is associated with a 6.5% rate of macroscopic residual neoplasia. Although 45% of SSPs had neoplasia extending to the resection margin, rates of residual neoplasia at surveillance colonoscopy were low. These results suggest that when feasible en bloc EMR is a reasonable option to resect SSPs ≥ 10 mm.

    2016-01-01

    Endoscopic resection of early gastric cancer is defined as incomplete when tumor cells are found at the resection margin upon histopathological examination. However, a tumor-positive resection margin does not always indicate residual tumor; it can also be caused by tissue contraction during fixation, by the cautery effect during endoscopic resection, or by incorrect histopathological mapping. Cases of highly suspicious residual tumor require additional endoscopic or surgical resection. For in...

    To determine the safety and efficacy of fibrin sealant for use in Müller muscle-conjunctiva resection ptosis repair. This was a retrospective review of a consecutive case series. All patients underwent Müller muscle-conjunctiva resection ptosis repair with fibrin sealant used for wound closure. Surgery was performed in a manner similar to a previously described technique, using fibrin tissue sealant rather that suture for wound closure. Postoperative symmetry was defined as MRD1 of each eyelid within 0.5 mm. Müller muscle-conjunctiva resection ptosis repair with fibrin sealant used for wound closure was performed on 53 eyelids of 33 patients. There were 27 female patients and 6 male patients. Twenty patients underwent bilateral ptosis repair and 13 patients underwent unilateral ptosis repair. Average follow-up was 17 weeks (range, 3 to 45 weeks). Mean preoperative MRD1 was 1.22 mm (range, -1.5 to 2.5 mm) in the right upper eyelid and 1.50 mm (range, 0 to 2 mm) in the left upper eyelid. Mean postoperative MRD1 was 3.11 mm (range, 2 to 4.5 mm) in the right upper eyelid and 3.12 mm (range, 1 to 4.5 mm) in the left upper eyelid. Postoperative symmetry was found in 32 of 33 patients (97%). We found no evidence of keratopathy or other complications attributable to the fibrin sealant. Müller muscle-conjunctiva resection ptosis repair with fibrin sealant used for wound closure may allow for predictable results with few complications and appears to be an acceptable alternative to traditional suture techniques.

    Full Text Available Background: Submucous myomas may be associated with menorrhagia, infertility and dysmenorrhea. Objective: The aim of this study was to determine the long term effects of submucousal myoma resection on menorrhagia and infertility; also to detect whether the type, size, and location of myoma affect the surgical success. Materials and Methods: .Totally 98 women referred to hysteroscopy for symptomatic submucousal fibroids (menorrhagia (n=51 and infertility (n=47 between 2005- 2010 were enrolled in this historical cohort study Pregnancy rates and menstrual improvement rates were compared according to myoma characteristics (size, type and location. Results: After a mean postoperative period of 23±10 months in 51 patients with excessive bleeding, 13 had recurrent menorrhagia (25%. In Other 38 patients excessive bleeding was improved (75%. The improvement rates by location and myoma type: lower segment 100%, fundus 92%, and corpus 63%; type 0 70%, type 1 78%, type 2 80%. The mean sizes of myoma in recurred and improved patients were 23.33 mm and 29.88 mm respectively. 28 of 47 infertile women spontaneously experienced thirty pregnancies (60%. Pregnancy rates according to myoma location and type: lower segment 50%, fundus 57%, and corpus 80%; type 0 75%, type 1 62%, type 2 50%. The mean myoma size in patients who became pregnant was 30.38 mm; in patients who did not conceive was 29.95 mm. Conclusion: The myoma characetesitics do not affect improvement rates after hysteroscopic myomectomy in patients with unexplained infertility or excessive uterine bleeding.

    The aim of this study was to update our previous experience and describe long-term results after resection of non-small-cell lung cancer (NSCLC) invading the thoracic inlet. Patients from a single center undergoing resection of NSCLC invading the thoracic inlet were reviewed with data retrieved retrospectively from their charts. Sixty-five consecutive patients with a median age of 61 (32-76) years underwent resection of NSCLC invading the thoracic inlet from 1991 to 2011. Tumor location was divided into 5 anatomic zones from anterior to posterior. Fifty-two (80%) patients had induction therapy, mostly with 2 cycles of cisplatin-etoposide and 45 Gy of concurrent irradiation. All patients underwent at least first rib resection. Lobectomy was performed in 60 patients (92%). Twenty-four patients (37%) had vertebral resection. Arterial resections were performed in 7 patients (11%). Postoperative morbidity and mortality were 46% and 6%, respectively. Pathologic response to induction was complete (pCR) (n = 19) or nearly complete (pNR) (n = 12) in 31 patients (48%). Adjuvant treatment was administered in 14 (25%) patients. After a median follow-up of 20 (0-193) months, 34 patients are alive without recurrence. The overall 5-year survival reached 69%. Univariate analysis identified site of tumor within the thoracic inlet (p = 0.050), response to induction (p = 0.004), and presence of adjuvant treatment (p = 0.028) as survival predictors. Survival after resection of NSCLC invading the thoracic inlet in highly selected patients reached 69% at 5 years. Tumor location within the thoracic inlet, pathologic response to induction therapy, and adjuvant treatments were significant survival predictors. Copyright © 2014 The Society of Thoracic Surgeons.

    Local recurrence after resection of rectal cancer is usually regarded as being due to a 'failure' of surgery. The completeness of resection of the mesorectum has been proposed as an indicator of the 'quality' of the resection. We determined the prognostic value of macroscopic evaluation of rectal cancer resection specimens and the circumferential resection margin (CRM) after curative surgery. From 1999 to 2006, the macroscopic quality of the mesorectum and the CRM were prospectively assessed in 127 patients who underwent rectal cancer resection with curative intent (R0+R1). Chemoradiotherapy was administered for 61 tumours staged as locally advanced tumours (T3, T4 and N+). Univariate analysis of time to local recurrence and cancer-free survival were tested (Kaplan-Meier) and multivariate analysis calculated with a Cox regression model. The mesorectum was incomplete in 34 (26.8%) patients. At a median follow up of 34 months (range, 9-96 months), in the group with an adequate mesorectal excision, the cumulative risk of local recurrence at 5 years was 10%. This was 25% if the mesorectum was incomplete (P CRM and the mesorectal score as independent factors for local recurrence, and T and N status and the mesorectal score as independent factors for disease-free survival. The outcome of surgical treatment of rectal cancer is related to the completeness of mesorectal excision. It is a more discriminative prognostic factor than the classic tumour-node-metastasis (TNM) system. © 2011 The Authors.

    Hepatoblastoma is the most common primary malignant liver tumor in children and is usually diagnosed during the first 3 years of life. Overall survival has increased 50% due to chemotherapeutic schemes, expertise surgery centers, and liver transplantation. A retrospective collection of data was performed from pediatric patients with diagnosis of hepatoblastoma. Variables included demographic, diagnostic tools and histological classification; chemotherapy and surgical treatment; and outcomes and patient survival. The PRETEXT classification was applied, which included the risk evaluation, and according to the medical criterion in an individualized way, underwent resection or transplant. The morbidity of patients was evaluated by the Clavien-Dindo classification. Statistical analysis was performed according to the distribution of data and the survival analysis was carried out using the Kaplan-Meier method. The patients (n = 16) were divided in a resection group (n = 8) and a transplant group (n = 8). The median age at the time of diagnosis was 13.5 months. The motive for the initial consultation was the discovery of a mass; all patients had high levels of α-fetoprotein and an imaging study. Ten of 16 patients required chemotherapy before the surgical procedure. In the resection group, 5 of 8 patients were classified as Clavien I and 4 of 8 patients of the transplant group were classified as Clavien II. Patient survival at 30 months was 100% in the resection group and 65% in the liver transplantation group. To our knowledge, this is the first case report of pediatric patients with hepatoblastoma and liver resection or transplant in Colombia and Latin America. Our results are comparable with the series worldwide, showing that resection and transplant increase the survival of the pediatric patients with hepatoblastoma. It is important to advocate for an increase of reporting in the scientific literature in Latin America.

    Full Text Available Effective therapy preserving reproductive function in adenomyosis is warranted. From June 2003 to June 2004, patients diagnosed as having adenomyosis by transvaginal ultrasound and had symptoms of menorrhagia, dysmenorrhea, and pelvic pain were randomly allocated to either receive laparoscopic resection or myolysis. GnRH analog was given for 3 cycles after surgery. Within 6 months, symptoms were evaluated using questionnaires and at the end of follow up, adenomyosis volume was assessed by transvaginal ultra-sound. There were 20 patients included, 10 patients had resection and the rest underwent myolysis. Both procedures did not yield sig-nificant complications. Subjective evaluation by questionnaires was done in all patients. Three patients could not be evaluated objec-tively by transvaginal ultrasound, 2 patients resigned and 1 was pregnant. There was no significant difference in menorrhagia and dysmenorrhea reduction score between the 2 groups (p=0.399 and 0.213, respectively. In both groups, dysmenorrhea was reduced significantly after treatment. No significant statistical difference was found in median adenomyosis volume increment (p=0.630 be-tween the resection (median=+15.35% (-100-159} and myolysis groups (median=+48.43% (-100-553. Five patients were pregnant, 3 from the resection group and 2 from the myolysis group. Uterine rupture was found in 1 patient (from the myolysis group at the age of 8 months of pregnancy. The effectiveness of laparoscopic adenomyosis resection was not significantly different compared with lapa-rascopic myolysis as an alternative conservative surgery in treating symptomatic adenomyosis. Myolysis was not recommended for women who wish to be pregnant. (Med J Indones 2006; 15:9-17Keywords: laparascopy, resection, myolysis, conservative surgery, symptomatic adenomyosis

    In the recent International Study Group of Pancreatic Surgery (ISGPS) consensus on extended pancreatectomy, several issues on perioperative outcome and long-term survival remained unclear. Robust data on outcomes are sparse. The present study aimed to assess the outcome of extended pancreatectomy for borderline resectable and locally advanced pancreatic cancer. A consecutive series of patients with primary pancreatic adenocarcinoma undergoing extended pancreatectomies, as defined by the new ISGPS consensus, were compared with patients who had a standard pancreatectomy. Univariable and multivariable analysis was performed to identify risk factors for perioperative mortality and characteristics associated with survival. Long-term outcome was assessed by means of Kaplan-Meier analysis. The 611 patients who had an extended pancreatectomy had significantly greater surgical morbidity than the 1217 patients who underwent a standard resection (42·7 versus 34·2 per cent respectively), and higher 30-day mortality (4·3 versus 1·8 per cent) and in-hospital mortality (7·5 versus 3·6 per cent) rates. Operating time of 300 min or more, extended total pancreatectomy, and ASA fitness grade of III or IV were associated with increased in-hospital mortality in multivariable analysis, whereas resections involving the colon, portal vein or arteries were not. Median survival and 5-year overall survival rate were reduced in patients having extended pancreatectomy compared with those undergoing a standard resection (16·1 versus 23·6 months, and 11·3 versus 20·6 per cent, respectively). Older age, G3/4 tumours, two or more positive lymph nodes, macroscopic positive resection margins, duration of surgery of 420 min or above, and blood loss of 1000 ml or more were independently associated with decreased overall survival. Extended resections are associated with increased perioperative morbidity and mortality, particularly when extended total pancreatectomy is performed. Favourable

    High complication rates have been cited following olfactory groove meningioma (OGM) resection but data are lacking on attendant risk factors. We aimed to review the complications following OGM resection and identify prognostic factors. A retrospective review was performed on 34 consecutive patients who underwent primary OGM resection at a single London institution between March 2008 and February 2013. Collected data included patient comorbidities, pre-operative corticosteroid use, tumour characteristics, imaging features, operative details, extent of resection, histology, use of elective post-operative ventilation, complications, recurrence and mortality. Complication rate was 39%. 58% of complications required intensive care or re-operation. Higher complication rates occurred with OGM > 40 mm diameter versus ≤ 40 mm (53 vs. 28%; p = 0.16); OGM with versus without severe perilesional oedema (59 vs. 19%; p = 0.26), more evident when corrected for tumour size; and patients receiving 1-2 days versus 3-5 days of pre-operative dexamethasone (75 vs. 19%; p = 0.016). Patients who were electively ventilated post-operatively versus those who were not had higher risk tumours but a lower complication rate (17 vs. 44%; p = 0.36) and a higher proportion making a good recovery (83 vs. 55%; p = 0.20). Complete versus incomplete resection had a higher complication rate (50 vs. 23%; p = 0.16) but no recurrence (0 vs. 25%; p = 0.07). Risk of morbidity with OGM resection is high. Higher complication risk is associated with larger tumours and greater perilesional oedema. Pre-operative dexamethasone for 3-5 days versus shorter periods may reduce the risk of complications. We describe a characteristic pattern of perilesional oedema termed 'sabre-tooth' sign, whose presence is associated with a higher complication rate and may represent an important radiological prognostic sign. Elective post-operative ventilation for patients with high-risk tumours may reduce the risk of complications.

    Only a few reports describe chest wall reconstruction after sternal resection using Gore-Tex dual mesh, and very few reports describe the use of a vascularized rib to support the thoracic cage. We present a case of a breast cancer patient who underwent anterior chest wall resection for recurrent sternal cancer. Her sternoclavicular joints bilaterally and lower sternum were divided using an electric saw. The bony chest wall was reconstructed using Gore-Tex dual mesh, and a vascularized rib was used to bridge the space between the clavicular heads to support the thoracic cage. The patient's postoperative course was uneventful, without complications, such as paradoxical respiration or pneumonia.

    2016-01-01

    Conclusion: Imaging is essential in planning the operative treatment to detect the extent of the Caroli disease and define the extent of resection. Any residual disease due to inappropriate imaging planning may cost the patient another cycle of suffering and may need another surgical intervention as in our case. We recommend using intraoperative ultrasound for accurate determination of the line of resection.

    Robotic rectal cancer surgery is gaining popularity, but limited data are available regarding safety and efficacy. To compare robotic-assisted vs conventional laparoscopic surgery for risk of conversion to open laparotomy among patients undergoing resection for rectal cancer. Randomized clinical trial comparing robotic-assisted vs conventional laparoscopic surgery among 471 patients with rectal adenocarcinoma suitable for curative resection conducted at 29 sites across 10 countries, including 40 surgeons. Recruitment of patients was from January 7, 2011, to September 30, 2014, follow-up was conducted at 30 days and 6 months, and final follow-up was on June 16, 2015. Patients were randomized to robotic-assisted (n = 237) or conventional (n = 234) laparoscopic rectal cancer resection, performed by either high (upper rectum) or low (total rectum) anterior resection or abdominoperineal resection (rectum and perineum). The primary outcome was conversion to open laparotomy. Secondary end points included intraoperative and postoperative complications, circumferential resection margin positivity (CRM+) and other pathological outcomes, quality of life (36-Item Short Form Survey and 20-item Multidimensional Fatigue Inventory), bladder and sexual dysfunction (International Prostate Symptom Score, International Index of Erectile Function, and Female Sexual Function Index), and oncological outcomes. Among 471 randomized patients (mean [SD] age, 64.9 [11.0] years; 320 [67.9%] men), 466 (98.9%) completed the study. The overall rate of conversion to open laparotomy was 10.1%: 19 of 236 patients (8.1%) in the robotic-assisted laparoscopic group and 28 of 230 patients (12.2%) in the conventional laparoscopic group (unadjusted risk difference = 4.1% [95% CI, -1.4% to 9.6%]; adjusted odds ratio = 0.61 [95% CI, 0.31 to 1.21]; P = .16). The overall CRM+ rate was 5.7%; CRM+ occurred in 14 (6.3%) of 224 patients in the conventional laparoscopic group and 12 (5.1%) of

    This study aimed at evaluating the voiding patterns of adult patients who underwent hypospadias repair in childhood. Following IRB approval 103 (22.7%) of 449 adult patients who underwent hypospadias repair between 1978 and 1993 responded to the following questionnaires: International Prostate Symptom Score (I-PSS) and Short Form 12 questionnaire (SF-12). Uroflowmetry (UF) was performed for all patients. The patients were divided into three groups according to the primary meatus localization. Group I had 63 patients (61.5%) treated for glanular hypospadias, group II had 19 patients (18.4%) treated for distal hypospadias, and group III comprised the remaining 21 patients (20.4%) treated for proximal hypospadias. The mean ± SD I-PSS score for all patients who responded to the questionnaire was 2.3 ± 2.4, and UF was 21.1 ± 4.3 mL/s. The patients from groups I and III had fewer urinary symptoms compared with those of the group II: 1.3 ± 1.5, 5.5 ± 2.4, and 1.6 ± 1.4, respectively (p hypospadias repair in childhood had normal or mild voiding disturbance, with no effects on their physical or mental status.

    We investigated into association of quality of life(QOL)and prognosis of breast cancer patients who underwent neoadjuvant chemotherapy(NAC). We retrospectively studied 228 patients with breast cancer who were performed NAC during a period between 2007 and 2015. TheQ OL score was measured with"The QOL Questionnaire for Cancer Patients Treated with Anticancer Drugs(QOL-ACD)". We evaluate association between QOL score with antitumor effect and prognosis. Changes in the QOL score between before and after NAC were compared as well. We divided 2 groups by QOL-ACD scoreinto high and low groups. Therapeautic effect of NAC on 75 patients were pathological complete response(pCR). QOL-ACD score was not significantly associated with pCR rate in both high and low groups(p=0.199). High group was significantly associated with higher survival rate in both of disease free survival(p=0.009, logrank)and overall survival(p=0.040, logrank). QOLACD score decreased after NAC in both of pCR and non-pCR patients. In conclusion, QOL evaluation using QOL-ACD could be an indicator of breast cancer patients' prognosis who underwent NAC.

    The role of HLA-G in several clinical conditions related to reproduction has been investigated. Important polymorphisms have been found within the 5'URR and 3'UTR regions of the HLA-G promoter. The aim of the present study was to investigate 16 SNPs in the 5'URR and 14-bp insertion/deletion (ins/del) polymorphism located in the 3'UTR region of the HLA-G gene and its possible association with the implantation outcome in couples who underwent assisted reproduction treatments (ART). The case group was composed of 25 ART couples. Ninety-four couples with two or more term pregnancies composed the control group. Polymorphism haplotype frequencies of the HLA-G were determined for both groups. The Haplotype 5, Haplotype 8 and Haplotype 11 were absolute absence in ART couples. The HLA-G*01:01:02a, HLA-G*01:01:02b alleles and the 14-bp ins polymorphism, Haplotype 2, showed an increased frequency in case women and similar distribution between case and control men. However, this susceptibility haplotype is significantly presented in case women and in couple with failure implantation after treatment, which led us to suggest a maternal effect, associated with this haplotype, once their presence in women is related to a higher number of couples who underwent ART.

    A geriatric assessment is needed to identify high-risk elderly patients with gastric cancer. However, the current geriatric assessment has been considered to be either time-consuming or subjective. The present study aimed to investigate the predictive effect of sarcopenia on the postoperative complications for elderly patients who underwent radical gastrectomy. We conducted a prospective study of patients who underwent radical gastrectomy from August 2014 to December 2015. Computed tomography-assessed lumbar skeletal muscle, handgrip strength, and gait speed were measured to define sarcopenia. Sarcopenia was present in 69 of 240 patients (28.8%) and was associated with lower body mass index, lower serum albumin, lower hemoglobin, and higher nutritional risk screening 2002 scores. Postoperative complications significantly increased in the sarcopenic patients (49.3% versus 24.6%, P sarcopenia (odds ratio: 2.959, 95% CI: 1.629-5.373, P Sarcopenia, presented as a new geriatric assessment factor, was a strong and independent risk factor for postoperative complications of elderly patients with gastric cancer.

    Full Text Available Background. S100B protein, previously proposed as a consolidated marker of brain damage in congenital heart disease (CHD newborns who underwent cardiac surgery and cardiopulmonary bypass (CPB, has been progressively abandoned due to S100B CNS extra-source such as adipose tissue. The present study investigated CHD newborns, if adipose tissue contributes significantly to S100B serum levels. Methods. We conducted a prospective study in 26 CHD infants, without preexisting neurological disorders, who underwent cardiac surgery and CPB in whom blood samples for S100B and adiponectin (ADN measurement were drawn at five perioperative time-points. Results. S100B showed a significant increase from hospital admission up to 24 h after procedure reaching its maximum peak (P0.05 have been found all along perioperative monitoring. ADN/S100B ratio pattern was identical to S100B alone with the higher peak at the end of CPB and remained higher up to 24 h from surgery. Conclusions. The present study provides evidence that, in CHD infants, S100B protein is not affected by an extra-source adipose tissue release as suggested by no changes in circulating ADN concentrations.

    Full Text Available Objective: To observe the effect of different CO2 pneumoperitoneum pressure on the stress state in patients underwent gynecological laparoscopy. Methods: A total of 90 patients who were admitted in our hospital from February, 2015 to October, 2015 for gynecological laparoscopy were included in the study and divided into groups A, B, and C according to different CO2 pneumoperitoneum pressure. The changes of HR, BP, and PetCO2 during the operation process in the three groups were recorded. The changes of stress indicators before operation (T0, 30 min during operation (T1, and 12 h after operation (T2 were compared. Results: The difference of HR, BP, and PetCO2 levels before operation among the three groups was not statistically significant (P>0.05. HR, BP, and PetCO2 levels 30 min after pneumoperitoneum were significantly elevated when compared with before operation (P0.05. PetCO2 level 30 min after pneumoperitoneum in group B was significantly higher than that in group A (P0.05. Conclusions: Low pneumoperitoneum pressure has a small effect on the stress state in patients underwent gynecological laparoscopy, will not affect the surgical operation, and can obtain a preferable muscular relaxation and vision field; therefore, it can be selected in preference.

    Intestinal resections are frequently required for treatment of diseases involving the gastrointestinal tract, with Crohn’s disease and colon cancer being two common examples. Despite the frequency of these procedures, a significant knowledge gap remains in describing the inherent effects of intestinal resection on host physiology and disease pathophysiology. This article provides detailed instructions for an ileocolic resection with primary end-to-end anastomosis in mice, as well as essential aspects of peri-operative care to maximize post-operative success. When followed closely, this procedure yields a 95% long-term survival rate, no failure to thrive, and minimizes post-operative complications of bowel obstruction and anastomotic leak. The technical challenges of performing the procedure in mice are a barrier to its wide spread use in research. The skills described in this article can be acquired without previous surgical experience. Once mastered, the murine ileocolic resection procedure will provide a reproducible tool for studying the effects of intestinal resection in models of human disease. PMID:25406841

    Broad narrative review. To review the evolution, operative technique, outcomes, and complications associated with posterior vertebral column resection. A literature review of posterior vertebral column resection was performed. The authors' surgical technique is outlined in detail. The authors' experience and the literature regarding vertebral column resection are discussed at length. Treatment of severe, rigid coronal and/or sagittal malalignment with posterior vertebral column resection results in approximately 50-70% correction depending on the type of deformity. Surgical site infection rates range from 2.9% to 9.7%. Transient and permanent neurologic injury rates range from 0% to 13.8% and 0% to 6.3%, respectively. Although there are significant variations in EBL throughout the literature, it can be minimized by utilizing tranexamic acid intraoperatively. The ability to correct a rigid deformity in the spine relies on osteotomies. Each osteotomy is associated with a particular magnitude of correction at a single level. Posterior vertebral column resection is the most powerful posterior osteotomy method providing a successful correction of fixed complex deformities. Despite meticulous surgical technique and precision, this robust osteotomy technique can be associated with significant morbidity even in the most experienced hands.

    Laparoscopic resection is a standard procedure for gastric submucosal tumors. Herein, we analyzed the features of various laparoscopic approaches. Between January 2007 and November 2013, 168 consecutive patients who underwent laparoscopic resection for gastric submucosal tumors were enrolled. Patients' demographics and clinicopathologic and perioperative data were reviewed retrospectively. Among the 168 patients, exogastric wedge resection was performed in 99 cases (58.9%), single-port intragastric resection was performed in 30 cases (17.9%), eversion technique was used in 17 cases (10.1%), transgastric resection was performed in 8 cases (4.8%), and single-port wedge resection was performed in 6 cases (3.6%). The remaining cases underwent single-port exogastric wedge resection, laparoscopic and endoscopic cooperative surgery, or major resection. Mean age was 56.8 ± 13.3 years, and body mass index was 24.0 ± 3.2 kg/m(2). Mean operation time was 96.1 ± 58.9 min; laparoscopic proximal gastrectomy had the longest operation time (3 cases, 291.7 ± 129.0 min). In contrast, the laparoscopic eversion technique had the shortest operation time (82.6 ± 32.8 min). Pathologic data revealed a mean tumor size of 2.9 ± 1.2 cm (with a range of 0.8-8.0 cm). Tumors were most common on the body (98 cases, 58.3%), followed by the fundus (44 cases, 26.2%). Exophytic growth occurred in 39 cases (23.2%), endophytic growth occurred in 89 cases (53.0%), and dumbbell-type growth occurred in 40 cases (23.8%). Gastrointestinal stromal tumors occurred in 130 cases (77.4%), and schwannomas occurred in 23 (13.7%). Thirteen patients had postoperative complications (delayed gastric emptying in 5, stricture in 3, bleeding in 3, others in 2). The mean follow-up period was 28.8 ± 20.8 months, and there were three recurrences (1.8%) at 6, 19 and 31 months after the initial surgery. For gastric submucosal tumors with appropriate locations and growth types, laparoscopic tailored resection which

    When evaluating the effects of the preparation of the flexion gap on the extension gap in total knee arthroplasty (TKA), the effects of posterior condylar resection and osteophyte removal on the extension gap should be differentiated. Although the amount of osteophytes differs between patients, posterior condylar resection is a procedure that is routinely implemented in TKA. The aim of this study was to assess the effects of the resection of the posterior condyle of the femur on the extension gap in posterior-stabilized (PS) TKA. We enrolled 40 knees that underwent PS TKA between July 2010 and February 2011 with no or minimal osteophytes in the posterior compartment and a varus deformity of <15°. We measured the extension gap before and after the resection of the posterior condyle of the femur using a tensor under 20 and 40 lb of distraction force. Under 20 lb of distraction force, the average extension gap was 13.3 mm (standard deviation [SD], 1.6) before and 13.8 mm (SD, 1.6) after posterior condylar resection. Under 40 lb of distraction force, the average extension gap was 15.1 mm (SD, 1.5) before and 16.1 mm (SD, 1.7) after posterior condylar resection. The resection of the posterior condyle of the femur in PS TKA increased the extension gap. However, this increase was only by approximately 1 mm. In conclusion, posterior condylar resection does increase the extension gap by approximately 1 mm. However, in most case, this change in unlikely to be clinically important.

    Objective: To evaluate the prognostic implication of the negative conversion of predicted circumferential resection margin status before surgery in patients with locally advanced rectal cancer with predicted circumferential resection margin involvement. Methods: Thirty-eight patients (28 men, 10 women; median age, 61 years; age range, 39–80 years) with locally advanced rectal cancer with predicted circumferential resection margin involvement who underwent preoperative chemoradiotherapy followed by radical surgery were analyzed. Involvement of the circumferential resection margin was predicted on the basis of pre- and post-chemoradiotherapy magnetic resonance imaging. The primary endpoints were 3-year local recurrence-free survival and overall survival. Results: The median follow-up time was 41.1 months (range, 13.9–85.2 months). The negative conversion rate of predicted circumferential resection margin status after preoperative chemoradiotherapy was 65.8%. Patients who experienced negative conversion of predicted circumferential resection margin status had a significantly higher 3-year local recurrence-free survival rate (100.0% vs. 76.9%; P = 0.013), disease-free survival rate (91.7% vs. 59.3%; P = 0.023), and overall survival rate (96.0% vs. 73.8%; P = 0.016) than those who had persistent circumferential resection margin involvement. Conclusions: The negative conversion of the predicted circumferential resection margin status as predicted by magnetic resonance imaging will assist in individual risk stratification as a predictive factor for treatment response and survival before surgery. These findings may help physicians determine whether to administer more intense adjuvant chemotherapy or change the surgical plan for patients displaying resistance to preoperative chemoradiotherapy.

    We compared the safety and efficacy of aquablation and transurethral prostate resection for the treatment of lower urinary tract symptoms related to benign prostatic hyperplasia. In a double-blind, multicenter, prospective, randomized, controlled trial 181 patients with moderate to severe lower urinary tract symptoms related to benign prostatic hyperplasia underwent transurethral prostate resection or aquablation. The primary efficacy end point was the reduction in I-PSS (International Prostate Symptom Score) at 6 months. The primary safety end point was the development of Clavien-Dindo persistent grade 1, or 2 or higher operative complications. Mean total operative time was similar for aquablation and transurethral prostate resection (33 vs 36 minutes, p = 0.2752) but resection time was lower for aquablation (4 vs 27 minutes, p prostate resection experienced large I-PSS improvements. The prespecified study noninferiority hypothesis was satisfied (p prostate resection 26% and 42%, respectively, experienced a primary safety end point, which met the study primary noninferiority safety hypothesis and subsequently demonstrated superiority (p = 0.0149). Among sexually active men the rate of anejaculation was lower in those treated with aquablation (10% vs 36%, p = 0.0003). Surgical prostate resection using aquablation showed noninferior symptom relief compared to transurethral prostate resection but with a lower risk of sexual dysfunction. Larger prostates (50 to 80 ml) demonstrated a more pronounced superior safety and efficacy benefit. Longer term followup would help assess the clinical value of aquablation.

    Our objective was to determine the incidence and optimal management of chylothorax after pulmonary resection with complete thoracic mediastinal lymph node dissection (MLND). This is a retrospective review of patients who underwent pulmonary resection with MLND. Between January 2000 and December 2012, 2,838 patients underwent pulmonary resection with MLND by one surgeon (RJC). Forty-one (1.4%) of these patients experienced a chylothorax. Univariate analysis showed that lobectomy (p<0.001), a robotic approach (p=0.03), right-sided operations (p<0.001), and pathologic N2 disease (p=0.007) were significantly associated with the development of chylothorax. Multivariate analysis showed that lobectomy (p=0.011), a robotic approach (p=0.032), and pathologic N2 disease (p=0.027) remained predictors. All patients were initially treated with cessation of oral intake and 200 μg subcutaneous somatostatin every 8 hours. If after 48 hours the chest tube output was less than 450 mL/day and the effluent was clear, patients was given a medium-chain triglyceride (MCT) diet and were observed for 48 hours in the hospital. If the chest tube output remained below 450 mL/day, the chest tube was removed, they were discharged home with directions to continue the MCT diet and to return in 2 weeks. Patients were instructed to consume a high-fat meal 24 hours before their clinic appointment. If the patient's chest roentgenogram was clear at that time, they were considered "treated." This approach was successful in 37 (90%) patients. The 4 patients in whom the initial treatment was unsuccessful underwent reoperation with pleurodesis and duct ligation. Chylothorax after pulmonary resection and MLND occurred in 1.4% of patients. Its incidence was higher in those with pathologic N2 disease and those who underwent robotic resection. Nonoperative therapy is almost always effective. Copyright © 2014 The Society of Thoracic Surgeons. Published by Elsevier Inc. All rights reserved.

    2017-11-13

    N-acetylcysteine (NAC) has many uses in medicine; notable in the management of paracetamol toxicity, acute liver failure and liver surgery. The aim of this review was to critically appraise the published literature for the routine use of NAC in liver resection surgery. An electronic search was performed of EBSCOhost (Medline and CINAHL database), PubMed and the Cochrane Library for the period 1990-2016. MeSH headings: 'acetyl-cysteine', 'liver resection' and 'hepatectomy' were used to identify all relevant articles published in English. Following the search criteria used, three articles were included. Two of these studies were randomized controlled trials. All the studies collated data on morbidity and mortality. All three studies did not show a significant difference in overall complications rates in patients that underwent hepatic resection that had NAC infusion compared with patients that did not. In one study, NAC administration was associated with a higher frequency of grade A post-hepatectomy liver failure. In another study, a significantly higher incidence of delirium was observed in the NAC group, which led to the trial to be terminated early. The current published data do not support the routine use of NAC following liver resection. © 2017 Royal Australasian College of Surgeons.

    Robotic-assisted surgery offers a solution to fundamental limitations of conventional laparoscopic surgery, and its use is gaining wide popularity. However, the application of this technology has yet to be established in hepatic surgery. A retrospective analysis of our prospectively collected liver surgery database was performed. Over a 6-month period, all consecutive patients who underwent robotic-assisted hepatic resection for a liver neoplasm were included. Demographics, operative time, and morbidity encountered were evaluated. A total of 7 robotic-assisted liver resections were performed, including 2 robotic-assisted single-port access liver resections with the da Vinci-Si Surgical System (Intuitive Surgical Sunnyvalle, Calif.) USA. The mean age was 44.6 years (range, 21-68 years); there were 5 male and 2 female patients. The mean operative time (± SD) was 61.4 ± 26.7 minutes; the mean operative console time (± SD) was 38.2 ± 23 minutes. No conversions were required. The mean blood loss was 100.7 mL (range, 10-200 mL). The mean hospital stay (± SD) was 2 ± 0.4 days. No postoperative morbidity related to the procedure or death was encountered. Our initial experience with robotic liver resection confirms that this technique is both feasible and safe. Robotic-assisted technology appears to improve the precision and ergonomics of single-access surgery while preserving the known benefits of laparoscopic surgery, including cosmesis, minimal morbidity, and faster recovery.

    Complete surgical resection is the treatment of choice for tailgut cysts, because of their malignant potential and tendency to regrow if incompletely resected. We report our experience of treating patients with tailgut cysts, and discuss diagnostics, surgical approaches, and follow-up. We performed extended distal rectal segmental resection of the tailgut cyst, with rectoanal anastomosis. We report the clinical, radiological, pathological, and surgical findings, describe the procedures performed, and summarize follow-up data. Two patients underwent en-bloc resection of a tailgut cyst, the adjacent part of the levator muscle, and the distal rectal segment, followed by an end-to-end rectoanal anastomosis. There was no evidence of anastomotic leakage postoperatively. At the time of writing, our patients were relapse-free with no, or non-limiting, symptoms of anal incontinence, respectively. This surgical approach appears to have a low complication rate and good recovery outcomes. Moreover, as the sphincter is preserved, so is the postoperative anorectal function. This approach could result in a low recurrence rate.

    The study aim was to analyse the safety and feasibility of laparoscopic intersphincteric resection with stapled coloanal anastomosis for low rectal cancer. Between March 2009 and August 2010, 22 patients underwent laparoscopic intersphincteric resection with a stapled coloanal anastomosis without a diverting ileostomy. The results were compared retrospectively with hand-sewn coloanal anastomoses performed between January 2001 and May 2009, which included 55 open and 38 laparoscopic intersphincteric resections. The morbidity comparison only included data relevant to the anastomosis. Function was compared using the Saito function questionnaire and the Wexner score and only involved data relevant to the laparoscopy. The anastomotic complication rates were similar for fistula, bleeding and neorectal mucosal prolapse (P = 0.526, P = 0.653 and P = 0.411, respectively). Anastomotic leakage and stricture formation of the stapled coloanal anastomosis were significantly lower than those of the hand-sewn coloanal anastomosis (P = 0.037 and P = 0.028, respectively). There were no significant differences in the Saito function questionnaire and the Wexner score between the stapled and hand-sewn coloanal anastomotic groups (all P > 0.05). Laparoscopic intersphincteric resection with a stapled coloanal anastomosis is technically feasible and is less likely to result in anastomotic leakage and stricture formation than a hand-sewn anastomosis.

    To investigate the risk factors for the initial bowel resection and postoperative recurrence in a cohort of patients with Crohn disease(CD). A total of 216 consecutive patients who were regularly followed up in the Department of Gastroenterology at the First Affiliated Hospital of Sun Yat-sen University between 2003 and 2009 were included. Probabilities for initial intestinal resection were calculated with Kaplan-Meier method. The influence of concomitant covariates on the cumulative probability rates was examined using Cox proportional hazard model. The risk of postoperative recurrence, including endoscopic recurrence, clinical recurrence and surgical recurrence, was also investigated during the follow-up. Logistic analysis was performed for the risk factors of recurrence. The median follow-up was 55 months. A total of 44 patients(20.4%) underwent bowel resection. The cumulative frequency of surgery was 11%, 25%, and 45% at 1, 5, and 10 years after initial onset. Multivariate analyses showed that age at diagnosis and disease behavior were independent risk factors for initial intestinal resection(Pdisease was the only independent risk factor for clinical recurrence(Pdisease behavior are associated with the probability of initial surgery. The presence of perianal disease is associated with a higher risk of clinical recurrence.

    Recently, minimize incisions has led to a reduction in the number of ports, and has led to transumbilical single-port surgery. We evaluated the treatment result of single-port, intragastric, full thickness resections for gastric SMTs. In addition, we introduce a novel intracorporeal knot tying method. From August 2010 to March 2011, five patients underwent single-port intragastric, full thickness gastric wedge resections. After performing a gastrostomy, a single port was inserted into the stomach. After full thickness resection, the defect in the gastric wall was sutured by full thickness interrupted suture and a new knot tying technique. The mean operative time was 129 ± 21.0 min and the mean mass size was 3.0±0.6 cm. There were two very low-risk GISTs, 2 leiomyomas, and 1 carcinoid. The post-operative course was uneventful in all patients. The mean hospital stay was 7.2±1.2 days. Single-port intra-gastric full thickness resection with novel intracorporeal knot tying method is feasible and safe. novel intracorporeal knot tying method is a very useful knot tying method. We expect the application of novel intracorporeal knot tying method to be diverse and broad.

    Late-onset and solitary recurrence of gastric signet ring cell (SRC) carcinoma is rare. We report a successful surgical resection of late solitary locoregional recurrence after curative gastrectomy for gastric SRC carcinoma. The patient underwent total gastrectomy for advanced gastric carcinoma at age 52. Seven years after the primary operation, he visited us again with sudden onset of abdominal pain and vomiting. We finally decided to perform an operation, based on a diagnosis of colon obstruction due to the recurrence of gastric cancer by clinical findings and instrumental examinations. The laparotomic intra-abdominal findings showed that the recurrent tumor existed in the region surrounded by the left diaphragm, colon of splenic flexure, and pancreas tail. There was no evidence of peritoneal dissemination, and peritoneal lavage fluid cytology was negative. We performed complete resection of the recurrent tumor with partial colectomy, distal pancreatectomy, and partial diaphragmectomy. Histological examination of the resected specimen revealed SRC carcinoma, identical in appearance to the previously resected gastric cancer. We confirmed that the intra-abdominal tumor was a locoregional gastric cancer recurrence in the stomach bed. The patient showed a long-term survival of 27 months after the second operation. In the absence of effective alternative treatment for recurrent gastric carcinoma, surgical options should be pursued, especially for late and solitary recurrence.

    Full Text Available Introduction. Simultaneous resection of primary colorectal carcinoma (CRC and synchronous liver metastases (SLMs is subject of debate with respect to morbidity in comparison to staged resection. The aim of this study was to evaluate our initial experience with this approach. Methods. Five patients with primary CRC and a clinical diagnosis of SLM underwent combined laparoscopic colorectal and liver surgery. Patient and tumor characteristics, operative variables, and postoperative outcomes were evaluated retrospectively. Results. The primary tumor was located in the colon in two patients and in the rectum in three patients. The SLM was solitary in four patients and multiple in the remaining patient. Surgical approach was total laparoscopic (2 patients or hand-assisted laparoscopic (3 patients. The midline umbilical or transverse suprapubic incision created for the hand port and/or extraction of the specimen varied between 5 and 10 cm. Median operation time was 303 (range 151–384 minutes with a total blood loss of 700 (range 200–850 mL. Postoperative hospital stay was 5, 5, 9, 14, and 30 days. An R0 resection was achieved in all patients. Conclusions. From this initial single-center experience, simultaneous laparoscopic colorectal and liver resection appears to be feasible in selected patients with CRC and SLM, with satisfying short-term results.

    Full Text Available Introduction: We expanded upon our previous experience using involved-field fractionated radiotherapy (IFRT as an alternative to whole brain radiotherapy (WBRT or stereotactic radiosurgery (SRS for patients with surgically resected brain metastases.Material and Methods: All patients with single brain metastases who underwent surgical resection followed by IFRT at our institution from 2006-2013 were evaluated. Local recurrence-free survival, distant failure-free survival and overall survival were determined. Analyses were performed associating clinical variables with local recurrence and distant failure. Salvage approaches and toxicity of treatment for each patient were also assessed.Results: Median follow-up was 19.1 months. Fifty-six patients were treated with a median dose of 40.05 Gy/15 fractions with IFRT to the resection cavity. Local recurrence-free survival was 91.4%, distant failure-free survival was 68.4%, and overall survival was 77.7% at 12 months. No variables were associated with increased local recurrence, however melanoma histopathology and infratentorial location were associated with distant failure on multivariate analysis. Local recurrences were salvaged in 5/8 patients, and distant failures were salvaged in 24/29 patients. Two patients developed radionecrosis.Conclusions: Adjuvant IFRT is feasible and safe for well-selected patients with surgically resected single brain metastases. Acceptable rates of local control and salvage of distal intracranial recurrences continue to be achieved with continued follow-up.

    We reviewed our ten-year experience with surgical en-bloc chest wall and vertebral resection for sarcoma invading the spine, and verified five-year survival and feasibility of this aggressive surgery. From 1994 to 1999, 13 patients underwent surgical en-bloc resection for primary sarcoma of the chest wall involving the spine. Concurrent pulmonary resection was performed in 12 cases. A single hemi-vertebrectomy was performed in 2 patients, a triple hemi-vertebrectomy in 2, a complete vertebrectomy in 4, a triple complete vertebrectomy in 5. Significative morbidity occurred in 1 patient who had lower limbs paralysis (9%). Perioperative mortality occurred in 2 patients (15.4%): 1 operative death for bleeding and 1 patients for a adult respiratory distress syndrome (ARDS). The overall five-year survival was 30.8%, excluding the 2 perioperative deaths the five-year survival resulted 36.4%. In spite of the limited number of patients, the morbidity and mortality outcome and the five-year survival leads us to think that surgery is the main therapy for primary chest wall sarcomas involving the spine. En-bloc chest wall and vertebral resection is a safe and effective treatment.

    Full Text Available BACKGROUND: Laparoscopic surgery has been reported to be one of the approaches for total mesorectal excision (TME in rectal cancer surgery. Intersphincteric resection (ISR has been reported as a promising method for sphincter-preserving operation in selected patients with very low rectal cancer. METHODS: We try to underline the important surgical issues surrounding the management of patients with low rectal cancer indicated to laparoscopic intersphincteric resection (ISR. From January 2007 till now, 35 patients with very low rectal cancer underwent laparoscopic TME with ISR. We report and analyze the results from them RESULTS: Conversion to open surgery was necessary in one (3% patient. The median operation time was 293 min and median estimated blood loss was 40 ml. The pelvic plexus was completely preserved in 32 patients. There was no mortality. Postoperative complications occurred in three (9% patients. The median length of postoperative hospital stay was 11 days. Macroscopic complete mesorectal excision was achieved in all cases. Complete resection (R0 was achieved in 21 (91% patients.CONCLUSIONS: Laparoscopic TME with ISR is technically feasible and a safe alternative to laparotomy with favorable short-term postoperative outcomes. The literature research made by us found that the laparoscopic approach can be underwent in most patients with low rectal cancer in which laparoscopic ISR represents a feasible alternative to conventional open surgery.

    This study was designed to evaluate the use of human amniotic membrane for ocular surface reconstruction after conjunctival squamous cell carcinoma resection. Amniotic membrane was obtained at the time of cesarean section and was preserved at -80 masculineC in glycerol and cornea culture media at a ratio of 1:1. The inclusion criteria were patients presenting proliferating lesions suggestive of squamous cell carcinoma (flat or elevated white lesions resembling "fish meat") that involve the conjunctiva, limbus and cornea. Eight eyes of 8 patients with conjunctival "squamous cell carcinoma" underwent tumor resection with amniotic membrane transplantation. Three of these cases underwent total corneal epitheliectomy and amniotic membrane transplantation associated with limbal autograft. Mean follow-up time was 17.8 months (range, 10-35 months). In four patients (71.4%) surgical treatment was successful, with good ocular surface stability. In two patients (28.6%) results were partially successful, with mild cicatricial alterations. One patient was excluded from the study due to aggressive tumor recurrence with intraocular invasion that needed to be removed with exenteration. This study suggests that amniotic membrane transplantation is a good alternative for ocular surface reconstruction after conjunctival squamous cell carcinoma resection.

    A frequent complication for the diabetic patient is neuropathic ulceration on the plantar surface of the first metatarsophalangeal (MTP) joint which can be difficult to manage. Debridement and resection arthroplasty with temporary external fixation and VAC dressing (Kinetic Concepts Inc, San Antonio, TX) is an alternative operative treatment to amputation. This study examined the outcomes of one center's experience with patients who have undergone this procedure. This retrospective cohort study examined patients who underwent the procedure between March 2002 and March 2010. Information was obtained on relevant outcomes including: the initial procedure, secondary procedures on either foot, total time in external fixation, time until amputation, cause of ulceration and co-morbid conditions. During the study period, 16 patients underwent resection arthroplasty with external fixation for first MTP ulceration. Fourteen of these patients had underlying diabetes mellitus, one had Charcot-Marie-Tooth disease and one had neuropathy of unknown cause. All were available for followup at the end of the study period. Median followup was 38 (range, 3 to 96) months. At latest followup, six patients required amputation, either transmetatarsal or transtibial, to treat their recurring ulceration. Resection arthroplasty with temporary external fixation appears to be a safe, effective and possible alternative to amputation for the treatment of neuropathic ulceration of the first MTP.

    Resection of retroperitoneal tumors is usually perfomed using the anterior retroperitoneal approach. Our report presents an innovative method utilizing a robotic surgical system. A 50-yr-old male patient visited our hospital due to a known paravertebral mass. Magnetic resonance imaging showed a well-encapsulated mass slightly abutting the abdominal aorta and left psoas muscle at the L4-L5 level. The tumor seemed to be originated from the prevertebral sympathetic plexus or lumbosacral trunk and contained traversing vessels around the tumor capsule. A full-time robotic transperitoneal tumor resection was performed. Three trocars were used for the robotic camera and working arms. The da Vinci Surgical System® provided delicate dissection in the small space and the tumor was completely removed without damage to the surrounding organs and great vessels. This case demonstrates the feasibility of robotic resection in retroperitoneal space. Robotic surgery offered less invasiveness in contrast to conventional open surgery. PMID:21218046

    The authors describe neurologic deficit (sensory, motor, and sphincteral) resulting from sacrifice of the sacral nerve roots removed during resection of the sacrum. The anatomical and functional bases of sphincteral continence and the amount of neurologic deficit are discussed based on level of sacral resection. A large review of the literature on the subject is reported and discussed. The authors emphasize how the neurophysiological bases of sphincteral continence (rectum and bladder) and of sexual ability are still not well known, and how the literature reveals disagreement on the subject. A score system is proposed to evaluate neurologic deficit. The clinical model of neurologic deficit caused by resection of the sacrum may be extended to an evaluation of post-traumatic deficit.

    Full Text Available Cushing’s syndrome (CS may lead to severe maternal and fetal morbidities and even mortalities in pregnancy. However, pregnancy complicates the diagnosis and treatment of CS. This study describes a 26-year-old pregnant woman admitted with hypertension-induced headache. Hormonal analyses performed due to her cushingoid phenotype revealed a diagnosis of adrenocorticotropic hormone- (ACTH- independent CS. MRI showed a 3.5 cm adenoma in her right adrenal gland. After preoperative metyrapone therapy, she underwent a successful unilateral laparoscopic adrenalectomy at 14-week gestation. Although she had a temporary postoperative adrenal insufficiency, hormonal analyses showed that she has been in remission since delivery. Findings in this patient, as well as those in previous patients, indicate that pregnancy is not an absolute contraindication for laparoscopic adrenalectomy. Rather, such surgery should be considered a safe and efficient treatment method for pregnant women with cortisol-secreting adrenal adenomas.

    Compare the visual acuity of patients who underwent cataract surgery by phacoemulsification with IOL AcrySof(®) toric implantation versus AcrySof(®) IQ and evaluate the reduction of cylindrical diopters (CD) in the postoperative period. Analytical and retrospective study of 149 eyes with 1 or more diopters of regular symmetrical keratometric astigmatism, which underwent cataract surgery by phacoemulsification. The eyes were divided into two groups: the toric group with 85 eyes and the non-toric group with 64 eyes. In the pre-operative phase, topographic data and refraction of each eye to be operated were assessed. In the postoperative phase, refraction and visual acuity with and without correction were measured. The preoperative topographic astigmatism ranged from 1.00 to 5.6 DC in both groups. Average reduction of 1.37 CD (p<0.001) and 0.16 CD (p=0.057) was obtained for the toric and non-toric group when compared to the refractive astigmatism, respectively. Considering visual acuity without correction (NCVA), the toric group presented 44 eyes (51.7%) with NCVA of 0 logMAR (20/20) or 0.1 logMAR (20/25) and the toric group presented 7 eyes (10.93%) with these same NCVA values. The results show that patients with a significant keratometric astigmatism presented visual benefits with the toric IOL implantation. The reduction of the use of optical aids may be obtained provided aberrations of the human eye are corrected more accurately. Currently, phacoemulsification surgery has been used not only for functional improvement, but also as a refraction procedure.

    To determine the effects of total parenteral nutrition (TPN) and enteral nutrition (EN) on biochemical and clinical outcomes in pancreatic cancer patients who underwent pancreaticoduodenectomy. From the year 2006 to 2008, 60 patients who underwent pancreaticoduodenectomy in Tianjin Third Central Hospital were enrolled in this study. They were randomly divided into the EN group and the TPN group. The biochemical and clinical parameters were recorded and analyzed between the two groups. There was no significant difference in the nutritional status, liver and kidney function, and blood glucose levels between the TPN and EN groups on the preoperative day, the 1st and 3 rd postoperative days. However, on the 7th postoperative day, there was significant difference between the two groups in 24 h urinary nitrogen, serum levels of, total protein (TP), transferrin (TF), alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), and γ-glutamyl transpeptadase (GGT), blood urea nitrogen (BUN) and creatinine (Cr). On the 14th postoperative day, there was a significant difference between the two groups in terms of urinary levels of 24 h nitrogen, TP, TF, retinol binding protein, ALT, AST, ALP, GGT, total bilirubin, direct bilirubin, BUN, Cr, and glucose. The incidence of delayed gastric emptying in the EN and TPN groups was 0% and 20%, respectively. Moreover, the incidence of pancreatic fistulas and hemorrhages in the EN group were 3.6% and 3.6%, versus 26.7% and 30% in the TPN group, respectively. EN is better than TPN for pancreatic cancer patients who received pancreaticoduodenectomy.

    Hepatic surgery has been performed on condition that the liver regenerates after hepatic resection, and the development of liver anatomy due to Glisson, Rex, and Couinaud has thrown light on hepatic surgery Understanding of feeding and drainage vessels became feasible for systemic hepatic resection; however, it seems to have been the most important problem to control the bleeding during hepatic resection. New types of devices such as cavitron ultrasonic surgical aspirator (CUSA) and Microwave coagulation were exploited to control blood loss during hepatic surgery. Pringle maneuver for exclusion feeding vessels of the liver and the decrease of central venous pressure during anesthesia enabled further decrease of blood loss. Nowadays, 3D-CT imaging may depict feeding and drainage vessels in relation to liver mass, and surgeons can simulate hepatic surgery in virtual reality before surgery, allowing hepatectomy to be performed without blood transfusion. Thus, hepatic resection has been a safe procedure, but there's been a significant research on how much of the liver can be resected without hepatic failure. A prediction scoring system based on ICGR15, resection rates, and age is mostly reliable in some criteria. Even if hepatectomy is performed with a good prediction score, the massive bleeding and associated infection may induce postoperative hepatic failure, while the criteria of postoperative hepatic failure have not yet established. Hepatic failure is supposed to be induced by the apoptosis of mature hepatocytes and necrosis originated from microcirculation disturbance of the liver. Prostaglandin E1 for the improvement of microcirculation, steroid for the inhibition of cytokines inducing apoptosis, and blood purification to exclude cytokines have been tried separately or concomitantly. New therapeutic approaches, especially hepatic regeneration from the stem cell, are expected. (author)

    Tracheal resection and reconstruction (TRR) is the treatment of choice for most patients with tracheal stenosis or tracheal tumors. Anesthesia for TRR offers distinct challenges, especially for the less experienced practitioner. This article explores the preoperative assessment, strategies for induction and emergence from anesthesia, the essential coordination between the surgical and anesthesia teams during airway excision and anastomosis, and postoperative care. The most common complications are reviewed. Targeted readership is practitioners with less extensive experience in managing airway surgery cases. As such, the article focuses first on the most common proximal tracheal resection. Final sections discuss specific considerations for more complicated cases. Copyright © 2012 Elsevier Inc.

    Introduction Mucosal malignant melanoma of the anorectum is a rare and aggressive disease, in which early diagnosis is difficult. The prognosis remains extremely poor, irrespective of the treatment. We share our experience in treating this malignancy at our centre in South India. Methods This study describes a retrospective analysis of 31 cases of anorectal melanoma presented to our centre between January 2001 and December 2013. Results Twenty-two patients (71%) presented with metastasis and had a median overall survival of nine months. None of the 22 patients survived for two years. Nine patients (29%) had curative surgery, in the form of abdominoperineal resection (six patients), abdominoperineal resection with bilateral inguinal node dissection (one patient), abdominoperineal resection with liver resection (one patient) and posterior exenteration (one patient). In patients who underwent curative surgery, the median overall survival was 15 months and disease-free survival was nine months, with a two-year overall survival of 22%. Conclusions Anorectal melanoma is an aggressive disease with a poor prognosis. The majority of patients present with distant metastases. Prognosis depends on stage at presentation. Early diagnosis and surgical resection may improve the overall outcome. Newer modalities such as immunotherapy and targeted therapies such as anti-CTLA4 monoclonal antibody and anti-programmed cell death protein 1 monoclonal antibodies have radically changed the management of mucosal melanoma and may, in the future, improve the overall prognosis of anorectal melanoma.

    Postoperative pancreatic fistula (POPF) and its complications remain problems. This study evaluated combination treatment with modified Blumgart anastomosis and an original infection control method (complete packing method) following pancreatic head resection. This study included 374 consecutive patients who underwent pancreatic head resection: 103 patients underwent Cattell-Warren anastomosis (CWA); 170 patients underwent modified Kakita anastomosis (KA); and 101 patients underwent modified Blumgart anastomosis with the complete packing method (BAC). The outcomes of the KA and BAC groups were compared statistically. The POPF rate was significantly lower in the BAC group than in the KA group (28.8% vs 2.97%; p anastomosis and the complete packing method is a simple and useful method for reducing the incidence of POPF and postoperative complications.

    Full Text Available Background: Segmental resection of bone in Giant Cell Tumor (GCT around the knee, in indicated cases, leaves a gap which requires a complex reconstructive procedure. The present study analyzes various reconstructive procedures in terms of morbidity and various complications encountered. Materials and Methods: Thirteen cases (M-six and F-seven; lower end femur-six and upper end tibia -seven of GCT around the knee, radiologically either Campanacci Grade II, Grade II with pathological fracture or Grade III were included. Mean age was 25.6 years (range 19-30 years. Resection arthrodesis with telescoping (shortening over intramedullary nail ( n=5, resection arthrodesis with an intercalary allograft threaded over a long intramedullary nail ( n=3 and resection arthrodesis with intercalary fibular autograft and simultaneous limb lengthening ( n=5 were the procedure performed. Results: Shortening was the major problem following resection arthrodesis with telescoping (shortening over intramedullary nail. Only two patients agreed for subsequent limb lengthening. The rest continued to walk with shortening. Infection was the major problem in all cases of resection arthrodesis with an intercalary allograft threaded over a long intramedullary nail and required multiple drainage procedures. Fusion was achieved after two years in two patients. In the third patient the allograft sequestrated. The patient underwent sequestrectomy, telescoping of fragments and ilizarov fixator application with subsequent limb lengthening. The patient was finally given an ischial weight relieving orthosis, 54 months after the index procedure. After resection arthrodesis with intercalary autograft and simultaneous lengthening the resultant gap (~15cm was partially bridged by intercalary nonvascularized dual fibular strut graft (6-7cm and additional corticocancellous bone graft from ipsilateral patella. Simultaneous limb lengthening with a distal tibial corticotomy was performed on an

    Patient immobilization is essential factor for successful radiation therapy and major problem is reproducibility to maintain patient position during total radiation therapy period. Purpose of this study is evaluation for usefulness of the custom made immobilization device for the anteroperitoneal resection patients with rectal cancer. The object of this study were patients who underwent anteroperitoneal resection and undergo radiation therapy at present with rectal cancer. We made immobilization device for patient individually and analyzed its set up reproducibility, patient position deviation and errors. There was 5 mm-10 mm deviation in patient position without individual immobilization device, but we improved the deviation within few mm limitation with individual immobilization device. Custom made immobilization device was very helpful for anteroperitoneal resection patient with rectal cancer. We improved the patient position deviation within few mm limitation, shorten the set up time and we could give the comfort to patients.

To determine, in pediatric patients with neuromuscular deformity undergoing vertebral column resection (VCR), the (1) characteristics of the surgery performed; (2) amount of pelvic obliquity restoration, and coronal and sagittal correction achieved; (3) associated blood loss and complications; and (4) extent to which curve type and VCR approach influenced correction, blood loss, and complications. VCR allows for correction of severe, rigid spinal deformity. This technique has not been previously reported in children with neuromuscular disorders. We retrospectively reviewed the records of 23 children with neuromuscular disorders (mean age, 15 years) and spinal deformities (severe scoliosis, 9; global kyphosis or angular kyphosis, 4; kyphoscoliosis, 10) who underwent VCR. The Student t test was used to compare correction differences (statistical significance, P < 0.05). A mean 1.5 vertebrae (27 thoracic and 6 lumbar) were resected per patient. Significant corrections were achieved in pelvic obliquity (11°, from 19° ± 13° to 8° ± 7°), in major coronal curve (56°, from 94° ± 36° to 38° ± 20°), and in major sagittal curve (46°, from 86° ± 37° to 40° ± 19°). There was no difference in correction between various curve types. VCR was associated with substantial blood loss (mean, 76% [estimated blood loss per total blood volume]), which correlated with patient weight and operating time. Overall, 6 patients experienced major complications: spinal cord injury, pleural effusion requiring chest tube insertion, pneumonia, pancreatitis, deep wound infection, and prominent implant requiring revision surgery. There were no deaths or permanent neurological injuries. VCR achieved significant pelvic obliquity restoration and coronal and sagittal correction in children with neuromuscular disorders and severe, rigid spinal deformity. However, this challenging procedure involves the potential for major complications.

    Purpose: To evaluate the local control rates, survival rates, and patterns of failure for esophageal cancer patients receiving preoperative concurrent chemotherapy and hyperfractionated radiotherapy followed by esophagectomy. Methods and Materials: From May 1993 through January 1997, 94 patients with resectable esophageal cancers received continuous hyperfractionated radiation (4,800 cGy/40 fx/4 weeks), with concurrent FP chemotherapy (5-FU 1 g/m 2 /day, days 2-6, 30-34, CDDP 60 mg/m 2 /day, days 1, 29) followed by esophagectomy 3-4 weeks later. If there was evidence of disease progression on preoperative re-evaluation work-up, or if the patient refused surgery, definitive chemoradiotherapy was delivered. Minimum follow-up time was 2 years. Results: All patients successfully completed preoperative treatment and were then followed until death. Fifty-three patients received surgical resection, and another 30 were treated with definitive chemoradiotherapy. Eleven patients did not receive further treatment. Among 91 patients who received clinical reevaluation, we observed 35 having clinical complete response (CR) (38.5%). Pathologic CR rate was 49% (26 patients). Overall survival rate was 59.8% at 2 years and 40.3% at 5 years. Median survival time was 32 months. In 83 patients who were treated with surgery or definitive chemoradiotherapy, the esophagectomy group showed significantly higher survival, disease-free survival, and local disease-free survival rates than those in the definitive chemoradiation group. Conclusion: Preoperative chemoradiotherapy in this trial showed improved clinical and pathologic tumor response and survival when compared to historical results. Patients who underwent esophagectomy following chemoradiation showed decreased local recurrence and improved survival and disease-free survival rates compared to the definitive chemoradiation group

  10. Rectovaginal fistula after low anterior resection for rectal cancer healed by nonoperative treatment

    Shigenobu Emoto

    Full Text Available Background: Rectovaginal fistula (RVF is a serious complication after colorectal anastomosis using a double-stapling technique. RVF following this procedure has been considered to be refractory to conservative treatment. Case presentation: A 75-year-old woman who underwent laparoscopy-assisted low anterior resection for early rectal cancer developed RVF on the 12th postoperative day. Conservative treatment was chosen and was successful. She was discharged from the hospital after 3 weeks with a normal oral diet. Colonoscopy on the 50th postoperative day showed that the RVF was closed. Conclusion: Conservative treatment may be effective for RVF after colorectal anastomosis using a double-stapling technique when there is no evidence of defecation through the vagina.

    This study aims to evaluate the efficacy of processed images to predict postoperative appearance following levator resection. Analysis involved 109 eyes from 65 patients with blepharoptosis who underwent advancement of levator aponeurosis and Müller's muscle complex (levator resection). Predictive images were prepared from preoperative photographs using the image processing software (Adobe Photoshop ® ). Images of selected eyes were digitally enlarged in an appropriate manner and shown to patients prior to surgery. Approximately 1 month postoperatively, we surveyed our patients using questionnaires. Fifty-six patients (89.2%) were satisfied with their postoperative appearances, and 55 patients (84.8%) positively responded to the usefulness of processed images to predict postoperative appearance. Showing processed images that predict postoperative appearance to patients prior to blepharoptosis surgery can be useful for those patients concerned with their postoperative appearance. This approach may serve as a useful tool to simulate blepharoptosis surgery.

    Full Text Available We report a rare case of postoperative colon cancer recurrence who presented with hematuria 13 years after resection of the primary colonic cancer. The patient was 72 years of age and underwent surgical resection of sigmoid colon cancer at another regional hospital in 1994. Since June 2007, this patient has complained of hematuria and bloody stool. On physical examination, tenderness and a hard, indurated mass was palpable in the lower mid-abdomen. Abdominal computed tomography showed a metastatic tumor at the lower midline peritoneum with invasion of the adjacent abdominal wall. Her serum carcinoembryonic antigen level was elevated to 32 ng/dL. Histopathology revealed metastatic colonic adenocarcinoma in the jejunum and abdominal wall.

    Full Text Available Marginal mandibular resection to treat neoplasms leads to loss of alveolar bone and teeth at the affected side. Consequently patient suffers with poor masticatory performance and esthetic disfigurement, which we need to restore with the help of prosthodontic rehabilitation. The success of rehabilitation of these patients depends on strategic treatment planning and choice of most suitable treatment modality. In this article, case of a patient has been presented who underwent marginal mandibular resection and reported with many limiting factors like obliterated buccal and lingual sulci, attachment of lingual frenum and lower lip at the level of alveolar ridge and Macroglossia. Impression making and fabrication of a retentive prosthesis were the main challenges. Therefore, a modified impression technique was used to fabricate mandibular cast partial denture with extracoronal semi precision attachments to enhance the retention of the prosthesis.

    The neurosurgical treatment of skull base temporal encephalocele for patients with epilepsy is variable. We describe two adult cases of temporal lobe epilepsy (TLE) with spheno-temporal encephalocele, currently seizure-free for more than two years after anterior temporal lobectomy (ATL) and lesionectomy sparing the hippocampus without long-term intracranial electroencephalogram (EEG) monitoring. Encephaloceles were detected by magnetic resonance imaging (MRI) and confirmed by maxillofacial head computed tomography (CT) scans. Seizures were captured by scalp video-EEG recording. One case underwent intraoperative electrocorticography (ECoG) with pathology demonstrating neuronal heterotopia. We propose that in some patients with skull base temporal encephaloceles, minimal surgical resection of herniated and adjacent temporal cortex (lesionectomy) is sufficient to render seizure freedom. In future cases, where an associated malformation of cortical development is suspected, newer techniques such as minimally invasive EEG monitoring with stereotactic-depth EEG electrodes should be considered to tailor the surrounding margins of the resected epileptogenic zone.

    Full Text Available Abdominal tumors that can grow through vascular lumen and spread to the right heart are rare. Although these tumors have different histologic aspects, they may cause similar abdominal and cardiac symptoms and are a serious risk factor for pulmonary embolism and sudden death when they reach the right atrium and tricuspid valve. The best treatment is radical surgical resection of the entire tumor using cardiopulmonary bypass with or without deep hypothermia and total circulatory arrest. We report the cases of two patients, the first with leiomyosarcoma of the inferior vena cava and the other with intravenous leiomyomatosis of the uterus that showed intravascular growth up to right atrium and ventricle, who underwent successful radical resection in a one-stage procedure with the use of cardiopulmonary bypass. We discuss the clinical and histologic aspects and imaging diagnosis and review the literature.

    A 2 yr old castrated male Pomeranian was evaluated for a 6 wk history of chronic vomiting, intermittent anorexia, and lethargy. Physical examination revealed a palpable, nonpainful, soft-tissue mass in the midabdominal area. Abdominal radiographs and ultrasound revealed a focal, eccentric thickening of the jejunal wall with associated jejunal mural foreign body and partial mechanical obstruction. Following diagnosis of a partial intestinal obstruction as the cause of chronic vomiting, the patient underwent general anesthesia for a laparoscopic-assisted, midjejunal resection and anastomosis using a single-incision laparoscopic surgery port. The patient was discharged the day after surgery, and clinical signs abated according to information obtained during a telephone interview conducted 2 and 8 wk postoperatively. The dog described in this report is a unique case of partial intestinal obstruction treated by laparoscopic-assisted resection and anastomosis using a single-incision laparoscopic surgery port.

    By analyzing seroma volume changes in the patients who underwent Partial breast radiation therapy after breast conserving surgery, we try to contribute to the improvement of radiotherapy effect. Enrolled 20 patients who underwent partial breast radiation therapy by ViewRay MRIdian System were subject. After seeking for the size of the removed sample in the patients during surgery and obtained seroma volume changes on a weekly basis. On the Basis of acquired volume, it was compared with age, term from start of the first treatment after surgery, BMI (body mass index) and the extracted sample size during surgery. And using the ViewRay MRIdian RTP System, the figure was analyzed by PTV(=seroma volume + margin) to obtain a specific volume of the Partial breast radiation therapy. The changes of seroma volume from MR simulation to the first treatment (a week) is 0~5% in 8, 5~10% in 3, 10 to 15% in 2, and 20% or more in 5 people. Two patients(A, B patient) among subjects showed the biggest change. The A patient's 100% of the prescribed dose volume is 213.08 cc, PTV is 181.93 cc, seroma volume is 15.3 cc in initial plan. However, while seroma volume decreased 65.36% to 5.3 cc, 100% of the prescribed dose volume was reduced to 3.4% to 102.43 cc and PTV also did 43.6% to 102.54 cc. In the case of the B patient, seroma volume decreased 42.57% from 20.2 cc to 11.6 cc. Because of that, 100% of the prescribed dose volume decreased 8.1% and PTV also did to 40%. As the period between the first therapy and surgery is shorter, the patient is elder and the size of sample is smaller than 100 cc, the change grow bigger. It is desirable to establish an adaptive plan according to each patient's changes of seroma volume through continuous observation. Because partial breast patients is more sensitive than WBRT patients about dose conformity in accordance with the volume change.

    The circumferential resection margin (CRM) is a key prognostic factor after rectal cancer resection. We sought to identify factors associated with CRM involvement (CRM+). A retrospective review was performed of the National Cancer Database, 2004-2011. Patients with rectal cancer who underwent radical resection and had a recorded CRM were included. Multivariable analysis of the association between clinicopathologic characteristics and CRM was performed. Tumor CRM+. Of 23,464 eligible patients, 13.3% were CRM+. Factors associated with CRM+ were diagnosis later in the study period, lack of insurance, advanced stage, higher grade, undergoing APR, and receiving radiation. Nearly half of CRM+ patients did not receive neoadjuvant therapy. CRM+ patients who did not receive neoadjuvant therapy were more likely to be female, older, with more comorbidities, smaller tumors, earlier clinical stage, advanced pathologic stage, and CEA-negative disease compared to those who received it. Factors associated with CRM+ include features of advanced disease, undergoing APR, and lack of health insurance. Half of CRM+ patients did not receive neoadjuvant treatment. These represent cases where CRM status may be modifiable with appropriate pre-operative selection and multidisciplinary management. Copyright © 2016 IJS Publishing Group Limited.

    One of the main drawbacks in the surgery of large craniopharyngiomas is the presence of a prefixed optic chiasm. Our main objective in this study is to compare the predictive value of the optic nerve length and optic chiasm location on large craniopharyngiomas' extent of resection. We retrospectively studied 21 consecutive patients with large craniopharyngiomas who underwent tumor resection through the trans-eyebrow supraorbital approach. Clinical and radiological findings on preoperative MRI were recorded, including the optic chiasm location classified as prefixed, postfixed or normal. We registered the optic nerve length measured intraoperatively prior to tumor removal and confirmed the measurements on preoperative MRI. Using a linear regression model, we calculated a prediction formula of the percentage of the extent of resection as a function of optic nerve length. On preoperative MRI, 15 patients were considered to have an optic chiasm in a normal location, 3 cases had a prefixed chiasm, and the remaining 3 had a postfixed chiasm. In the group with normal optic chiasm location, a wide range of percentage of extent of resection was observed (75-100%). The percentage of extent of resection of large craniopharyngiomas was observed to be dependent on the optic nerve length in a linear regression model (p < 0.0001). According to this model in the normal optic chiasm location group, we obtained an 87% resection in 9-mm optic nerve length patients, a 90.5% resection in 10-mm optic nerve length patients and 100% resection in 11-mm optic nerve length patients. Optic chiasm location provides useful information to predict the percentage of resection in both prefixed and postfixed chiasm patients but not in the normal optic chiasm location group. Optic nerve length was proven to provide a more accurate way to predict the percentage of resection than the optic chiasm location in the normal optic chiasm location group.

    The current treatment model for the management of malignant biliary obstruction is to place a plastic stent for unstaged pancreatic cancer. In patients with unresectable disease but a life expectancy of more than 6 months, self-expandable metal stents (SEMS) are favored because of their more prolonged patency. We analyzed the efficacy and cost-effectiveness of covered SEMS (CSEMS) in patients with pancreatic cancer and distal biliary obstruction without regard to surgical resectability. Between March 2001 and March 2005, 101 consecutive patients with obstructive jaundice secondary to pancreatic cancer underwent placement of a CSEMS. Patients with resectable tumor were offered pancreaticoduodenectomy. A model was developed to compare the costs of CSEMS and polyethylene and DoubleLayer stents. A total of 21 patients underwent staging laparoscopy, of whom 16 had a resection (76%). The 85 patients who did not have a resection had a mean survival of 5.9 months (range 1-25 months) and a mean CSEMS patency duration of 5.5 months (range 1-16 months). Life-table analysis demonstrated CSEMS patency rates of 97% at 3 months, 85% at 6 months, and 68% at 12 months. In a cost model that accounted for polyethylene and DoubleLayer stent malfunction and surgical resections, initial CSEMS placement (3177 euros per patient) was a less costly intervention than either DoubleLayer stent placement (3224 euros per patient) or polyethylene stent placement with revision (3570 euros per patient). Covered SEMS are an effective treatment for distal biliary obstructions caused by pancreatic carcinoma. Their prolonged patency and removability makes them an attractive option for biliary decompression, regardless of resectability. The strategy of initial covered SEMS placement might be the most cost-effective strategy in these patients.

    The optimal surgical strategy for treating colorectal cancer with synchronous liver metastases is subject to debate. The current study sought to evaluate the outcomes of simultaneous colorectal cancer and liver metastases resection in a single center. Prospectively collected data on all patients with synchronous colorectal liver metastases who underwent simultaneous resection with curative intent were analyzed retrospectively. Patient outcomes were compared depending on the primary tumor location and type of liver resection (major or minor). Between January 2005 and August 2016, 108 patients underwent simultaneous resection of primary colorectal cancer and liver metastases. The tumor was localized to the right side of the colon in 24 patients (22%), to the left side in 40 (37%), and to the rectum in 44 (41%). Perioperative mortality occurred in 3 patients (3%). Postoperative complications were noted in 32 patients (30%), and most of these complications (75%) were grade 1 to 3 according to the Clavien-Dindo classification. Neither perioperative mortality nor the rate of postoperative complications after simultaneous resection differed among patients with cancer of the right side of the colon, those with cancer of the left side of the colon, and those with rectal cancer (4%, 2.5%, and 2%, respectively, p = 0.89) and (17%, 33%, and 34%, respectively; p = 0.29)]. The 5-year overall survival of the entire sample was 54% and the 3-year overall survival was 67 %. In conclusion, simultaneous resection for primary colorectal cancer and liver metastases is a safe procedure and can be performed without excess morbidity in carefully selected patients regardless of the location of the primary tumor and type of hepatectomy.

    To compare fibrin sealant (Tisseel) versus suture for wound closure in Müller muscle-conjunctiva resection ptosis repair. The charts of 114 patients (211 eyelids) who had undergone Müller muscle-conjunctiva resection were retrospectively reviewed. Suture versus Tisseel were used for wound closure. Preoperative and postoperative eyelid measurements, postoperative symmetry within 0.5 mm, and complications were compared. Müller muscle-conjunctiva resection ptosis repair was performed on 211 eyelids of 114 patients. Seventeen cases were unilateral and 97 cases were bilateral. Method of wound closure included suture (45 eyelids of 31 patients) versus Tisseel (166 eyelids of 83 patients). For the suture group, the mean preoperative MRD1 was 1.2 mm and the postoperative MRD1 was 3.0 mm; the difference was 1.9. For the Tisseel group, the mean preoperative MRD1 was 1.2 mm and the postoperative MRD1 was 3.0 mm; the difference was 1.8. The 2 groups did not differ statistically in preoperative (p = 0.97) or postoperative MRD1 values (p = 0.53), the difference (p = 0.63), or postoperative symmetry within 0.5 mm (p = 0.39). In the suture group, complications included moderate to severe pain (10%), suture granuloma (6%), corneal abrasion (3%), loose suture (3%), and persistent keratopathy (3%). We found no evidence of keratopathy attributable to the Tisseel (p = 0.0001). This difference in the prevalence of complications was statistically significant (p = 0.0001). Four patients in the suture group (13%) underwent subsequent procedures including suture granuloma removal (2) and suture removal (1); 1 patient (3%) required levator resection. Three patients in the Tisseel group (4%) subsequently underwent levator resection. Müller muscle-conjunctiva resection ptosis repair using fibrin sealant for wound closure offers comparable eyelid position results compared with suture. Use of Tisseel showed fewer postoperative complications and was associated with fewer subsequent surgical

    The adjunctive role of magnetic resonance imaging of the liver before pancreatic ductal adenocarcinoma has been unclear. We evaluated whether the combination of hepatic magnetic resonance imaging with multidetector computed tomography using a pancreatic protocol (pCT) could help surgeons select appropriate candidates and decrease the risk of early recurrence. We retrospectively enrolled 167 patients in whom complete resection was achieved without grossly visible residual tumor; 102 patients underwent pCT alone (CT group) and 65 underwent both hepatic magnetic resonance imaging and pCT (magnetic resonance imaging group). By adding hepatic magnetic resonance imaging during preoperative evaluation, hepatic metastases were newly discovered in 3 of 58 patients (5%) without hepatic lesions on pCT and 17 of 53 patients (32%) with indeterminate hepatic lesions on pCT. Patients with borderline resectability, a tumor size >3 cm, or preoperative carbohydrate antigen 19-9 level >1,000 U/mL had a greater rate of hepatic metastasis on subsequent hepatic magnetic resonance imaging. Among 167 patients in whom R0/R1 resection was achieved, the median overall survival was 18.2 vs 24.7 months (P = .020) and the disease-free survival was 8.5 vs 10.0 months (P = .016) in the CT and magnetic resonance imaging groups, respectively (median follow-up, 18.3 months). Recurrence developed in 82 (80%) and 43 (66%) patients in the CT and magnetic resonance imaging groups, respectively. The cumulative hepatic recurrence rate was greater in the CT group than in the magnetic resonance imaging group (P magnetic resonance imaging should be considered in patients with potentially resectable pancreatic ductal adenocarcinoma, especially those with high tumor burden.

    AIM: The aim of this study was to determine the sensitivity of ultrasonography for detecting hepatocellular carcinoma in patients who underwent surgical liver resection. MATERIALS AND METHODS: The preoperative ultrasonography reports of 103 patients who underwent hepatic resection surgery were retrospectively reviewed. The patients had chronic liver disease with good liver function and a relatively normal liver echotexture. The presence of a mass or masses in the resected part of the liver segments on preoperative ultrasonography was regarded as possible hepatocellular carcinoma, and these results were compared with the surgically resected hepatic lobes or segments. Accuracy for detection was assessed on a lesion-by-lesion basis, on a segment-by-segment basis, and on a patient basis. RESULTS: One hundred and fifty-seven hepatocellular carcinomas were found in 244 hepatic segments of 103 patients. One hundred and one of 157 hepatocellular carcinomas were detected using ultrasonography in 97 patients resulting in a sensitivity of 64%. In six patients, a solitary hepatocellular carcinoma was missed in each patient, a patient sensitivity being 94%. Using ultrasonography, 87 of 100 (87%) hepatocellular carcinomas larger than 2 cm in diameter, and 14 of 57 (25%) hepatocellular carcinomas 2 cm or smaller in diameter were revealed. On the basis of segment-by-segment analysis, the sensitivity was 78% (99 of 127 segments), specificity was 97% (114 of 117 segments), accuracy was 87% (213 of 244 segments), positive predictive value was 97% (99 of 102 segments), and negative predictive value was 80% (114 of 142 segments). CONCLUSION: In patients with chronic liver disease and good hepatic function, ultrasonography has a sensitivity of 94% in the identification of affected patients, but for individual lesions, the sensitivity is only 64%

    Robotic surgery was introduced as a platform for minimally invasive lung resection in Canada in October 2011. We present the first Canadian series of robotic pulmonary resection for lung cancer. Prospective databases at 2 institutions were queried for patients who underwent robotic resection for lung cancer between October 2011 and June 2015. To examine the effect of learning curves on patient and process outcomes, data were organized into 3 temporal tertiles, stratified by surgeon. A total of 167 consecutive patients were included in the study. Median age was 66 (range 27-88) years, and 46.1% ( n = 77) of patients were men. The majority of patients ( n = 141, 84%) underwent robotic lobectomy. Median duration of surgery was 270 (interquartile range [IQR] 233-326) minutes, and median length of stay (LOS) was 4 (IQR 3-6) days. Twelve patients (7%) were converted to thoracotomy. Total duration of surgery and console time decreased significantly ( p < 0.001) across tertiles, with a steady decline until case 20, followed by a plateau effect. Across tertiles, there was no significant difference in LOS, number of lymph node stations removed, or perioperative complications. The results of this case series are comparable to those reported in the literature. A prospective study to examine the outcomes and cost of robotic pulmonary resection compared with video-assisted thoracoscopic surgery should be done in the context of the Canadian health care system. We have presented the first consecutive case series of robotic lobectomy in Canada. Outcomes compare favourably to other series in the literature.

    Full Text Available Abstract Background Myocardial infarction can be difficult to diagnose after lung surgery. As recent diagnostic criteria emphasize serum cardiac markers (in particular serum troponin we set out to evaluate its clinical utility and to establish the long term prognostic impact of detected abnormal postoperative troponin levels after lung resection. Methods We studied a historic cohort of patients with primary lung cancer who underwent intended surgical resection. Patients were grouped according to known postoperative troponin status and survival calculated by Kaplan Meier method and compared using log rank. Parametric survival analysis was used to ascertain independent predictors of mortality. Results From 2001 to 2004, a total of 207 patients underwent lung resection for primary lung cancer of which 14 (7% were identified with elevated serum troponin levels within 30 days of surgery, with 9 (64% having classical features of myocardial infarction. The median time to follow up (interquartile range was 22 (1 to 52 months, and the one and five year survival probabilities (95% CI for patients without and with postoperative troponin elevation were 92% (85 to 96 versus 60% (31 to 80 and 61% (51 to 71 versus 18% (3 to 43 respectively (p T stage and postoperative troponin elevation remained independent predictors of mortality in the final multivariable model. The acceleration factor for death of elevated serum troponin after adjusting for tumour stage was 9.19 (95% CI 3.75 to 22.54. Conclusion Patients with detected serum troponin elevation are at high risk of early mortality with or without symptoms of myocardial infarction after lung resection.

    We sought to determine whether anesthetic type (general vs spinal) would influence cancer recurrence following transurethral resection of bladder tumors. With institutional ethics board approval we examined the electronic medical records of all patients who underwent transurethral bladder tumor resection for nonmuscle invasive urothelial bladder cancer between 2011 and 2013 at a single tertiary care center. Followup information was gathered on all patients in December 2016. The time to first cancer recurrence and the incidence of cancer recurrence were the main outcome measures. A total of 231 patients underwent 1 or more transurethral bladder tumor resections between 2011 and 2013. Of the 231 patients 135 received spinal anesthesia and 96 received general anesthesia. On univariable analysis the 135 patients who received spinal anesthesia had a longer median time to recurrence than the 96 who received general anesthesia (42.1 vs 17.2 months, p = 0.014). As anticipated, adjuvant therapies and risk category were associated with recurrence rates (p = 0.003 and 0.042, respectively). On multivariable analyses incorporating a priori variables of nonmuscle invasive bladder cancer risk stratification and postoperative therapies the patients who received general anesthesia had a higher incidence of recurrence (OR 2.06, 95% CI 1.14-3.74, p = 0.017) and an earlier time to recurrence (HR 1.57, 95% CI 1.13-2.19, p = 0.008) than those who received spinal anesthesia. Anesthetic type was not associated with cancer progression or overall mortality. Patients who received spinal anesthesia had a lower incidence of recurrence and a delayed time to recurrence following transurethral bladder tumor resection for nonmuscle invasive bladder cancer. These findings should prompt large-scale prospective studies to confirm this association. Copyright © 2018 American Urological Association Education and Research, Inc. Published by Elsevier Inc.

    Soft-tissue sarcomas most frequently metastasize to the lung. Surgical resection of pulmonary metastases is the primary treatment modality. Although lobectomy is widely acknowledged as the standard procedure to treat primary pulmonary tumors, the standard for pulmonary metastases is not well defined; furthermore, compromised lung function may tip the scales in favor of a less invasive approach. Here, we report the results of a patient treated with wedge resection and intraoperative cesium-131 ((131)Cs). A 58-year-old African American female was diagnosed with the American Joint Committee on Cancer Stage IIA mixed uterine leiomyosarcoma and underwent total abdominal hysterectomy and bilateral salpingo-oophorectomy followed by adjuvant external beam radiotherapy to a total dose of 45 Gy and vaginal brachytherapy to a total dose of 20 Gy. At 2 years, a routine CT scan of the chest revealed metastasis to right upper lobe of the lung. The patient's poor pulmonary function, related to a 45 pack-year smoking history and chronic emphysema, precluded a lobectomy. After the patient underwent a lung-sparing wedge resection of the pulmonary right upper lobe metastasis and intraoperative brachytherapy with (131)Cs seeds to a total dose of 80 Gy, she remained disease free in the implanted area. At a 2-year followup, imaging continued to reveal 100% local control of the area treated with wedge resection and intraoperative (131)Cs brachytherapy. The patient had no complications from this treatment. Such treatment approach may become an attractive option in patients with oligometastatic disease and compromised pulmonary function.

    Full Text Available ABSTRACT OBJECTIVES: To evaluate through the visual analog scale (VAS the pain in patients undergoing total knee replacement (TKR with different pressures of the pneumatic tourniquet. METHODS: An observational, randomized, descriptive study on an analytical basis, with 60 patients who underwent TKR, divided into two groups, which were matched: a group where TKR was performed with tourniquet pressures of 350 mmHg (standard and the other with systolic blood pressure plus 100 mmHg (P + 100. These patients had their pain assessed by VAS at 48 h, and at the 5th and 15th days after procedure. Secondarily, the following were also measured: range of motion (ROM, complications, and blood drainage volume in each group; the data were subjected to statistical analysis. RESULTS: After data analysis, there was no statistical difference regarding the incidence of complications (p = 0.612, ROM (p = 0.202, bleeding after 24 and 48 h (p = 0.432 and p = 0.254 or in relation to VAS. No correlation was observed between time of ischemia compared to VAS and bleeding. CONCLUSIONS: The use of the pneumatic tourniquet pressure at 350 mmHg or systolic blood pressure plus 100 mmHg did not influence the pain, blood loss, ROM, and complications. Therefore the pressures at these levels are safe and do not change the surgery outcomes; the time of ischemia must be closely observed to avoid major complications.

    There are increasingly more patients seeking minimally invasive procedures, which have become more effective and safer in reducing the signs of facial aging. This study included 40 female adult patients who voluntarily underwent selected minimally invasive procedures (filling with hyaluronic acid and botulinum toxin injection) for facial rejuvenation. All patients were followed for a period of 6 months. They were evaluated with the use of questionnaires, a quality-of-life questionnaire (DLQI), the self-esteem scale of Rosenberg (EPM/Rosenberg), and a pain scale. The minimally invasive procedures resulted in improvement in quality of life and self-esteem, which were stronger the first 3 months after the procedures but remained at a higher level than that before treatment, even after 6 months. Hyaluronic acid with lidocaine in the formula is more comfortable for the patient as it makes the injection less painful.

    Basal and squamous cell carcinomas are the most common malignant cutaneous lesions affecting the nose. With the rising incidence of skin cancers, plastic surgeons increasingly face nasal reconstruction challenges. Although multiple options exist, optimal results are obtained when "like is used to repair like". We aimed to introduce a simple algorithm for the reconstruction of nasal defects with local flaps, realizing that there is always more than one option for reconstruction. We retrospectively reviewed 163 patients who underwent nasal reconstruction after excision of non-melanoma skin cancer between March 2011 and April 2014. We analyzed the location of the defects and correlated them with the techniques used to reconstruct them. There were 66 males and 97 females (age, 21-98 years). Basal cell carcinoma was diagnosed in 121 patients and squamous cell carcinoma in 42. After tumor excision, all the defects were immediately closed by either primary closure or local flap options such as Limberg, Miter, glabellar, bilobed, nasolabial, V-Y advancement, and forehead flaps. Obtaining tumor-free borders and a pleasing aesthetic result are major concerns in nasal reconstruction. Defect reconstruction and cosmesis are as important as rapid recovery and quick return to normal daily activities, and these should be considered before performing any procedure, particularly in elderly patients.

    We investigated the risk factor of perioperative asthmatic attack and effectiveness of preventing treatment for asthmatic attack before operation. We performed retrospective chart review of one hundred eleven patients with asthma underwent general anesthesia and surgical intervention from January 2006 to October 2007 in our hospital. The rate of perioperative asthmatic attack were as follows; 10.2% (5 in 49 cases) in no pretreatment group, 7.5% (3 in 40 cases) in any pretreatments except for systemic steroid, and 4.5% (1 in 22 cases) in systemic steroid pretreatment group. Neither preoperative asthma severity nor duration from the last attack had significant relevancy to perioperative attack rate. The otolaryngological surgery, especially those have nasal polyp and oral surgery had high perioperative asthma attack rate, although there was no significant difference. We recommend the systemic steroid pretreatment for asthmatic patients, especially when they have known risk factor such as administration of the systemic steroid within 6 months, or possibly new risk factor such as nasal polyp, otolaryngological and oral surgery.

    Full Text Available Background. Hypothermia in the surgical patients can be the consequence of long duration of surgical intervention, general anesthesia and low temperature in operating room. Postoperative hypothermia contributes to a number of postoperative complications such as arrhythmia, myocardial ischemia, hypertension, bleeding, wound infection, coagulopathy, prolonged effect of muscle relaxants. External heating procedures are used to prevent this condition, but some investigations reported that infusion of aminoacids during surgery can induce thermogenesis and prevent postoperative hypothermia. Case report. We reported two males who underwent major colorectal surgery for rectal carcinoma. One patient received Aminosol 15% solution, 125 ml/h, while the other did not. The esophageal temperatures in both cases were measured every 30 minutes during the operation and 60 minutes after in Intensive Care Unit. We were monitoring blood pressure, heart rate, ECG, and shivering. Patient who received aminoacids showed ameliorated postoperative hypothermia without hypertension, arrhythmia, or shivering, while the other showed all symptoms mentioned above. Conclusion. According to literature data, as well as our findings, we can conclude that intraoperative intravenous treatment with amino acid solution ameliorates postoperative hypothermia along with its complications. .

    To determine the prevalence and spontaneous resolution of congenital hydrocele diagnosed in male neonates who underwent circumcision at our centre. All male neonates presented for circumcision at the University of Benin Teaching Hospital, Benin City, Nigeria between January 2002 and December 2006 were examined for the presence of hydrocele. Those diagnosed with this condition were recruited and followed up in a surgical outpatient clinic for 2 years. The number of cases of spontaneous resolution and age at which this occurred were documented on a structured pro forma. A total of 2715 neonates were circumcised and 128 (4.7%) were diagnosed with 163 cases of hydrocele, while 27 cases in 25 (0.9%) children failed to resolve at the age of 2 years. Neonatal hydrocele was bilateral in 112 (68.7%), and there were 20 (12.3%) right and 31 (19.0%) left. Among those with hydrocele, 28.1% were delivered preterm and resolution was spontaneous in many of them, with no observed significant statistical difference to those delivered full term (P=0.4740). Of the 163 hydrocele cases, 136 (83.4%) resolved spontaneously by age 18 months with peak resolution at 4-6 months. No spontaneous resolution occurred after 18 months and no hydrocele-related complication occurred during follow up. Neonates with congenital hydrocele should be observed for spontaneous resolution for at least 18 months before being subjected to surgery.

    To describe the psychological stress and quality of life experienced by women who underwent fertility treatment in Taiwan. Cross-sectional, correlational study. Recruitment was conducted and questionnaires administered at a reproductive medicine center in Chiayi City, Taiwan. Informed consent to participate was obtained from 126 women who sought fertility treatment at the center. The Chinese Fertility Problem Inventory and Fertility Quality of Life scale were used to measure participants' levels of fertility-related stress and fertility-related quality of life. Descriptive statistics, correlation, and regression analysis were used. Overall, participants reported low levels of fertility-related stress and fertility-related quality of life; however, they had relatively high levels of stress related to need for parenthood. Women who were older, had greater body mass indexes, and consumed coffee regularly had lower fertility-related quality of life. Social and relationship concerns and stress related to need for parenthood were significant predictors of low fertility-related quality of life. In a culture in which childbearing is generally an expectation and an important part of family life, women who experience infertility are at risk to experience fertility-related stress. Social support and family consultation might be offered to improve women's fertility-related quality of life.

    Resections involving oral cavity mucosa, bone, and skin present a unique challenge. Optimizing outcomes often requires technically demanding reconstruction. The purpose of this study is to evaluate outcomes of several reconstructive approaches for patients with composite through-and-through defects, with a focus on the osteocutaneous radial forearm free flap (RFFF). We conducted a retrospective evaluation of the cohort of patients treated for composite through-and-through defects with cutaneous involvement who underwent free flap reconstruction from August 2012 through October 2015. Seventeen patients received a single flap (12 cases of osteocutaneous RFFF), whereas 10 patients underwent a combination of flaps. Complication rates and functional outcomes were favorable in patients who underwent osteocutaneous RFFFs. The supraclavicular artery island flap (SCAIF) was used as a second flap in 3 cases. The osteocutaneous RFFF provides a valuable reconstructive option for complex composite resection defects involving skin. When 2 flaps are required, the SCAIF is a viable alternative to a second free flap or pectoralis flap. © 2018 Wiley Periodicals, Inc.

    Objective was to present our 8 year experience in the prevention of the obturator nerve reflex during transurethral resection of bladder tumors. This study was performed in Ataturk University Hospital between 1999 and 2007. We retrospectively reviewed the records of 89 patients with inferolateral bladder tumors, who underwent transurethral resection under epidural or general anesthesia and requested obturator nerve reflex inhibition. Epidural anesthesia was administered to 57 patients, while the remaining 32 patients underwent general anesthesia via mask; and succinylcholine was administered prior to resection. Of the 57 patients received epidural anesthesia, 18 were diagnosed as inferolateral bladder tumors during endoscopy and had to undergo general anesthesia. Obturator nerve block was attempted preoperatively in 39 patients. However, a nerve identification failure, hematoma and 4 obturator nerve reflex events, despite the block, were observed and these patients were subjected to general anesthesia with succinylcholine. Fifty-six patients (32 patients initially had general anesthesia and 24 converted from epidural to general anesthesia) were all given succinylcholine prior to resection. Due to its mechanisms of action, succinylcholine is completely effective and represents a simple alternative to obturator nerve block. No contraction was observed in any patient given succinylcholine. (author)

    IMPORTANCE Despite professional recommendations to delay elective colon resection for patients with uncomplicated diverticulitis, early surgery (after diverticulitis episodes. However, the relevance of these factors in early surgery has not been well tested, and most prior studies have focused on hospitalizations, missing outpatient events and making it difficult to assess guideline adherence in earlier interventions. OBJECTIVE To describe patterns of episodes of diverticulitis before surgery and factors associated with earlier interventions using inpatient, outpatient, and antibiotic prescription claims. DESIGN, SETTING, AND PARTICIPANTS This investigation was a nationwide retrospective cohort study from January 1, 2009, to December 31, 2012. The dates of the analysis were July 2014 to May 2015. Participants were immunocompetent adult patients (age range, 18-64 years) with incident, uncomplicated diverticulitis. EXPOSURE Elective colectomy for diverticulitis. MAIN OUTCOMES AND MEASURES Inpatient, outpatient, and antibiotic prescription claims for diverticulitis captured in the MarketScan (Truven Health Analytics) databases. RESULTS Of 87 461 immunocompetent patients having at least 1 claim for diverticulitis, 6.4% (n = 5604) underwent a resection. The final study cohort comprised 3054 nonimmunocompromised patients who underwent elective resection for uncomplicated diverticulitis, of whom 55.6% (n = 1699) were male. Before elective surgery, they had a mean (SD) of 1.0 (0.9) inpatient claims, 1.5 (1.5) outpatient claims, and 0.5 (1.2) antibiotic prescription claims related to diverticulitis. Resection occurred after fewer than 3 episodes in 94.9% (2897 of 3054) of patients if counting inpatient claims only, in 80.5% (2459 of 3054) if counting inpatient and outpatient claims only, and in 56.3% (1720 of 3054) if counting all types of claims. Based on all types of claims, patients having surgery after fewer than 3 episodes were of similar mean age compared with

    Proper femoral component alignment in the axial plane during total knee arthroplasty (TKA) depends on accurate bone cuts and soft tissue balancing. Two methods that are used to achieve this are "measured resection" and "gap balancing." However, a controversy exists as to which method is more accurate and leads to better outcomes. Therefore, the purpose of this study was to evaluate: (1) implant survivorship, (2) patient outcomes, (3) complications, and (4) radiographic analysis comparing patients who underwent TKA with either gap-balancing or measured resection techniques. A total of 214 consecutive patients (221 knees) underwent primary TKA by a single surgeon between 2011 and 2012. Component alignment was achieved by using measured resection in 116 knees and gap balancing was used in 105 knees. The patients had a mean age of 66 years (range, 44-86 years) and a mean body mass index of 32 kg/m 2 (range, 22-52 kg/m 2 ). Patient range-of-motion (ROM) and Knee Society (KS) function and pain scores, and radiographic assessment, were assessed preoperatively and postoperatively at ∼6 weeks, 3 months, 1 year, and then annually. The mean follow-up time was 3 years. A Kaplan-Meier's analysis was performed to calculate the survivorship. The aseptic survivorship was 98% in both the measured resection and gap-balancing groups. The mean ROM was not significantly different between the measured resection and gap-balancing groups (123 vs. 123 degrees, p  = 0.990). There were no significant differences between the two groups in terms of the KS function scores (86 vs. 85 points, p  = 0.829) or the KS pain scores (93 vs. 92 points, p  = 0.425). Otherwise, the radiographic evaluation at latest follow-up did not demonstrate any evidence of progressive radiolucencies or loosening, of any prosthesis. The results of this study found that at a mean follow-up of 3 years, both the measured resection and gap-balancing techniques achieved excellent survivorship and

    Osseous overgrowth is a common complication in children after humeral transcortical amputation. Capping tibial overgrowth with the proximal fibula has been shown to be the most effective treatment. However, best treatment practices are not clear for the humerus. We compared patients treated surgically for humeral osseous overgrowth with simple resection or autologous osteocartilaginous graft to determine if this treatment were as effective in the humerus as it has been in the tibia. A retrospective review of humeral amputees from 1987 to 2011 at a pediatric hospital was performed. Patients with 2 years follow-up who underwent surgical treatment for established humeral overgrowth were included. Patients initially managed with simple resection were compared with those managed with autologous osteocartilaginous grafts. Descriptive statistics were calculated for demographic and outcome variables. T tests and χ tests were used to compare differences between groups. Eighteen humeri in 16 patients met inclusion criteria. Mean age at surgery was 8.3 (2.6 to 13.6) years and mean follow-up was 6.3 (1.5 to 10.4) years. Thirteen humeri underwent simple resection, with recurrent overgrowth in 9, and revision surgery in 8 at a mean 2.6 years. Five humeri were primarily managed with autologous osteocartilaginous grafts. Two developed non-overgrowth-related complications at 1 and 42 months. Including revision procedures after simple resection, 10 humeri were managed with autologous osteocartilaginous grafts. Thirty percent (3/10) required revision surgery; however, there were no cases of recurrent overgrowth. χ comparison showed lower rates of complications (P=0.004) and reoperation (P=0.012) with capping as compared with simple resection. Autologous osteocartilaginous capping of the humerus has a significantly lower rate of complications and reoperation compared with simple resection. However, the capping procedure has the potential for other complications related to difficulty

    Full Text Available BACKGROUND: It remains unclear which patients can benefit from simultaneous resection of synchronous colorectal liver metastases (SCRLMs. This study aimed to examine the prognostic value of patient- and tumor-related factors in predicting long-term outcomes of patients undergoing simultaneous resection of SCRLMs and to help patients select a suitable therapeutic regimen and proper surveillance. METHODS: Clinicopathological and outcome data of 154 consecutive SCRLM patients who underwent simultaneous resection between July 2003 and July 2013 were collected from our prospectively established SCRLM data and analyzed with univariate and multivariate methods, and the prognostic index (PI was formulated based on the regression coefficients (β of the Cox model. The patients were classified into high- and low-risk groups according to the PI value; the cut-off point was the third quartile. RESULTS: The 5-year overall survival rate was 46%, and the 5-year disease-free survival rate was 35%. Five factors were found to be independent predictors of poor overall survival (OS by multivariate analysis: positive lymph node status, vascular invasion, BRAF mutation, the distribution of bilobar liver metastases (LMs and non-R0 resection of LMs. Compared to low PI (≤5.978, high PI (>5.978 was highly predictive of shorter OS. Three factors were found to be independent predictors of poor disease-free survival (DFS by multivariate analysis: tumor deposits, BRAF mutation and bilobar LM distribution. We also determined the PI for DFS. Compared to low PI (≤2.945, high PI (>2.945 was highly predictive of shorter DFS. CONCLUSIONS: Simultaneous resection of SCRLM may lead to various long-term outcomes. Patients with low PI have longer OS and DFS, while those with high PI have shorter OS and DFS. Thus, patients with high PI may receive more aggressive treatment and intensive surveillance, This model needs further validation.

    The traditional unilateral or bilateral buccogingival or bicoronal approach often seems to impose limitations on achieving complete resection and reconstruction of the extensive midfacial fibrous dysplasia. Therefore, we hypothesized that the midfacial degloving approach could be used for the correction of maxillary fibrous dysplasia, which has been primarily used for paranasal sinus lesions or nasopharyngeal tumor. The study involved 5 maxillofacial fibrous dysplasia patients who underwent a midfacial degloving surgical procedure. There were 4 male patients and 1 female patient with a mean age of 16.8 years. The average, mean follow-up duration was 17.8 months. A wide, subperiosteal dissection was made along the anterior wall of the maxilla and pyriform aperture over the level of the infraorbital foramen. A bilateral, circumferential, nasal vestibular incision and dissection allowed for bilateral degloving of the middle third of the face over the infraorbital rim. Then total or subtotal resection, followed by reconstruction using an iliac bone graft, was performed. The midface, degloving approach provided visualization of the medial maxillary wall, the pterygoid junction, nasofrontal suture, infraorbital rim, and laterally to the temporal process of the zygoma. Subtotal or total resection of the lesions and reconstruction with bone grafts was possible in all 5 patients, and there were no complications. There was also no visible facial scarring and all patients expressed satisfaction with the cosmetic outcome. The midfacial, degloving approach was found to be safe and effective for maxillofacial fibrous dysplasia, and nearly total resection was possible. This approach allows for a wider dissection and resection compared with the traditional buccogingival approaches, and there was no visible facial scarring.

    Introduction Tracheal stenosis following intubation is the most common indication for tracheal resection and reconstruction. Endoscopic dilation is almost always associated with recurrence. This study investigated first-line surgical resection and anastomosis performed in fit patients presenting with postintubation tracheal stenosis. Methods Between February 2011 and November 2014, a prospective study was performed involving patients who underwent first-line tracheal resection and primary anastomosis after presenting with postintubation tracheal stenosis. Results A total of 30 patients (20 male) were operated on. The median age was 23.5 years (range: 13-77 years). Seventeen patients (56.7%) had had previous endoscopic tracheal dilation, four (13.3%) had had tracheal stents inserted prior to surgery and one (3.3%) had undergone previous tracheal resection. Nineteen patients (63.3%) had had a tracheostomy. Eight patients (26.7%) had had no previous tracheal interventions. The median time of intubation in those developing tracheal stenosis was 20.5 days (range: 0-45 days). The median length of hospital stay was 10.5 days (range: 7-21 days). The success rate for anastomoses was 96.7% (29/30). One patient needed a permanent tracheostomy. The in-hospital mortality rate was 3.3%: 1 patient died from a chest infection 21 days after surgery. There was no mortality or morbidity in the group undergoing first-line surgery for de novo tracheal lesions. Conclusions First-line tracheal resection with primary anastomosis is a safe option for the treatment of tracheal stenosis following intubation and obviates the need for repeated dilations. Endoscopic dilation should be reserved for those patients with significant co-morbidities or as a temporary measure in non-equipped centres.

    Surgical treatment of acute complicated sigmoid diverticulitis is still under debate while elective treatment of recurrent diverticulitis has proven benefits. The aim of this study was to evaluate the clinical and histological outcome of acute and elective laparoscopic sigmoid colectomy in patients with diverticulitis. A retrospective review was conducted where 197 patients were analyzed undergoing laparoscopic sigmoid resection for acute complicated diverticulitis and recurrent diverticulitis. Single-stage laparoscopic resection and primary anastomosis were routinely performed using a 3-trocar technique. Recorded data included age, sex, American Society of Anesthesiologists (ASA)-score, operative time, duration of hospital stay, complications, and histological results. Ninety-one patients received laparoscopy for acute diverticular disease (group I) and 93 patients underwent elective laparoscopic sigmoid resection for diverticulitis (group II). M/F ratio was 49:42 for group I and 37:56 for group II. Mean operative time and hospital stay was similar in both groups. Majority of patients were ASA II in both groups. Rate of minor complications was 14.3 % in group I and 7.5 % in group II. Major complications were 2.2 % for acute treatment and 4.3 % for elective resections. No anastomotic leakage and no mortality occurred. In 32.3 % of the patients of elective group II, destruction of the colonic wall with pericolic abscess, fistulization, or fibrinoid purulent peritonitis were identified. Laparoscopic surgery for acute diverticular disease is safe and effective. Continuing bowl inflammations in histological specimens justify sigmoid resection in elective patients, but more effective pre-operative parameters need to be found to identify patients that would benefit from surgery during the initial episode.

    Although the deltoid muscle has been assumed to be an essential shoulder muscle, the full extent of postoperative functions of the upper extremity following its complete resection due to sarcoma has not been thoroughly investigated. In this study, we review patients who underwent wide resection for sarcoma in the deltoid muscle, followed by functional reconstruction using pedicled latissimus dorsi (LD) muscle transfer. Four patients with sarcoma arising in the deltoid muscle were reviewed. Tumor resection with a wide surgical margin resulted in loss of the entire deltoid muscle together with the axillary nerve. For reconstruction, the ipsilateral pedicled LD muscle was transferred on its neurovascular pedicle for use as a functional substitute. One case had local recurrence and the transferred LD myocutaneous flap was resected. There were no serious complications after the operation, and all flaps survived perfectly. Wound healing at both the recipient and donor sites was uneventful. Active abduction of the shoulder joint was >160° in all patients. The muscle manual test of shoulder flexion was good to normal and abduction was fair to good. Musculoskeletal Tumor Society scores were excellent in all cases and the average score was 92% (range, 87-93%). Our results suggest that removal of the entire deltoid muscle resulted in a slight impairment of function. Pedicled LD musculocutaneous flaps are useful for covering the defect that results from resection of the deltoid muscle and they contribute additional function to the affected shoulder.

    For patients undergoing liver resection that leaves an empty intraparenchymal cavity, traditional topical agents might be inadequate to achieve additional hemostasis. A new hemostatic expanding topical foam (BioFoam(®)) has been designed to provide a mechanical seal. The objective of this study was to report our preliminary results regarding the safety and the efficacy using this foam. Between 2009 and 2011, BioFoam(®) was used to fill a three-dimensional defect following liver resection in 14 patients. The operative results and postoperative course of these patients were compared to those of 14 matched controls who underwent liver resection but did not receive BioFoam(®). The two groups were similar in terms of demographics, indications for liver resection, type of surgical procedure, and type and duration of clamping. BioFoam(®) patients experienced significantly less operative blood loss (275 vs. 630 ml, p = 0.032) but similar operative transfusion rates (28.6 vs. 35.7 %, p = 0.686) compared to no-BioFoam(®) patients. The postoperative mortality was nil and no patient developed postoperative hemorrhage. While the two groups shared similar overall (64.3 vs. 57.1 %, p = 0.599) and major (28.6 vs. 14.3 %, p = 0.357) complications rates, BioFoam(®) patients experienced significantly higher major vascular thrombosis compared to no-BioFoam(®) patients (29 vs. 0 %, p = 0.04). In the BioFoam(®) group, major vascular thrombosis was associated with exposure of the vessel along the transection plane. While the clinical benefit of BioFoam(®) in high-risk liver resections leaving a deep parenchymal defect remains to be proven, the associated risk of vascular thrombosis should preclude its use in contact with major veins.

    To investigate cognitive outcomes after frontal lobe resection (FLR) for epilepsy in a consecutive single centre series. Neuropsychological examinations were performed prior to and two years (mean test interval 2.5 years) after surgery in 30 consecutive patients who underwent FLR. Cognitive outcome was evaluated with particular consideration to the site of surgery (lateral, premotor/SMA [supplementary motor area], mesial/orbital). Cognitive domains assessed were speed, language, memory, attention, executive functions and intelligence. 25 healthy controls were assessed at corresponding time points (mean test interval 3.0 years). Analyses were made both at group and individual levels. At baseline the patients performed below controls in variables depending on speed, executive functions, global and verbal intelligence. Two years after surgery, the analyses at the subgroup level indicated that the lateral resection group had less improvement than the controls in global intelligence, FSIQ (p=.037). However, at the individual level, the majority of the change scores (74-100%) were classified as within the normal range for all but one variable. The exception was the variable "Comprehension" (measuring verbal reasoning ability) with reliable declines in 44% (8/18) of the patients. This pattern of decline was observed in the lateral (4/7 patients) and premotor/SMA (4/7 patients) resection groups. Seizure outcome and side of surgery did not influence these results. The main finding was cognitive stability at group level two years after FLR. A reliable decline in verbal reasoning ability was rather common at an individual level, but only in the lateral and premotor/SMA resection groups. The lateral resection group also had less improvement than the controls in global intelligence. Copyright © 2015 British Epilepsy Association. Published by Elsevier Ltd. All rights reserved.

    The aim of this study was to evaluate the long-term outcomes of four patients with tracheal agenesis who underwent airway and esophageal/alimentary reconstruction. We reviewed the medical records of four long-term survivors of tracheal agenesis and collected the following data: age, sex, type of tracheal agenesis, method of reconstruction, nutritional management, and physical and neurological development. The patients consisted of three boys and one girl, who ranged in age from 77 to 109months. The severity of their condition was classified as Floyd's type I (n=2), II (n=1), or III (n=1). Mechanical respiratory support was not necessary in any of the cases. Esophageal/alimentary reconstruction was performed using the small intestine (n=2), a gastric tube (n=1), and the esophagus (n=1). The age at esophageal reconstruction ranged from 41 to 55months. All of the cases required enteral nutrition via gastrostomy. Three of the patients were able to swallow a small amount of liquid and one was able to take pureed food orally. The physical development of the subjects was moderately delayed-borderline in childhood. Neurological development was normal in two cases and slightly delayed in two cases. None of the long-term survivors of tracheal agenesis required the use of an artificial respirator, and their development was close to normal. Future studies should aim to elucidate the optimal method for performing esophageal reconstruction to allow tracheal agenesis patients to achieve their full oral intake.

    Roux-en-Y gastric bypass (RYGB) is a highly effective treatment for obesity and results in long-term weight loss and resolution of co-morbidities. However, weight regain may occur as soon as 1-2 years after surgery. This retrospective study aimed to investigate the prevalence of weight regain and possible preoperative predictors of this phenomenon after RYGB. An academic medical center in the United States. A total of 1426 obese patients (15.8% male) who underwent RYGB during January 2000 to 2012 and had at least a 2-year follow-up were reviewed. We included only patients who were initially successful, having achieved at least 50% excess weight loss at 1 year postoperatively. Patients were then categorized into either the weight regain group (WR) or sustained weight loss (SWL) group based upon whether they gained≥15% of their 1-year postoperative weight. Weight regain was observed in 244 patients (17.1%). Preoperative body mass index was similar between groups. Body mass index was significantly higher and percent excess weight loss was significantly lower in the WR group (Pweight regain was 19.5±9.3 kg and-.8±8.5 in the WR and SWL groups, respectively (Pweight loss. Moreover, a longer duration after RYGB was associated with weight regain. Multivariate analysis revealed that younger age was a significant predictor of weight regain even after adjusting for time since RYGB. The present study confirmed that a longer interval after RYGB was associated with weight regain. Younger age was a significant predictor of weight regain even after adjusting for time since RYGB. The findings of this study underscore the complexity of the mechanisms underlying weight loss and regain after RYGB. Future prospective studies are needed to further explore the prevalence, predictors, and mechanisms of weight regain after RYGB. Copyright © 2016 American Society for Bariatric Surgery.

    The study objective was to report the outcomes of biventricular repair in patients with double outlet right ventricle. Patients with double outlet right ventricle who underwent biventricular repair at Fuwai Hospital from January 2005 to December 2012 were included. Patients were excluded if double outlet right ventricle was combined with atrioventricular septal defect, heterotaxy syndrome, atrioventricular discordance, or univentricular physiology. A total of 380 consecutive patients with a mean age of 1.9 ± 2.1 years (range, 1 month to 6 years) were included. Varied types of biventricular repair were customized individually. Follow-up was 90.4% complete, and the mean follow-up time was 3.4 ± 3.9 years. There were 17 (4.5%) early deaths and 7 (2.1%) late deaths. Preoperative pulmonary hypertension was the only risk factor for early mortality. Postoperative significant left ventricular outflow tract obstruction was present in 9 survivors. Patients with noncommitted ventricular septal defect had a longer crossclamp time, longer cardiopulmonary bypass time, and higher incidence of postdischarge left ventricular outflow tract obstruction. There were 4 reoperations, all of which were caused by subaortic left ventricular outflow tract obstruction. All of the pressure gradients were decreased to less than 20 mm Hg after the modified Konno procedure with an uneventful postoperative course. Optimal results of varied types of biventricular repair for double outlet right ventricle have been acquired. Although noncommitted ventricular septal defect is technically difficult, the outcomes of patients are favorable. Late-onset left ventricular outflow tract obstruction is the main reason for reoperation but can be successfully relieved by the modified Konno procedure.

    Full Text Available The relationship between a perioperative change in sarcopenic status and clinical outcome of liver transplantation (LT is unknown. We investigated whether post-LT sarcopenia and changes in sarcopenic status were associated with the survival of patients.This retrospective study was based on a cohort of 145 patients from a single transplant center who during a mean of 1 year after LT underwent computed tomography imaging evaluation. The cross-sectional area of the psoas muscle of LT patients was compared with that of age- and sex-matched healthy individuals. The Cox proportional hazards regression model was used to determine whether post-LT sarcopenia and changes in sarcopenic status affect post-LT survival.The mean age at LT of the 116 male and 29 female patients was 50.2 ± 7.9 years; the mean follow-up duration was 51.6 ± 32.9 months. All pre-LT patients with sarcopenia still had sarcopenia 1 year after LT; 14 (15% patients had newly developed sarcopenia. The mean survival duration was 91.8 ± 4.2 months for non-sarcopenic patients and 80.0 ± 5.2 months for sarcopenic patients (log-rank test, p = 0.069. In subgroup analysis, newly developed sarcopenia was an independent negative predictor for post-LT survival (hazard ratio: 10.53, 95% confidence interval: 1.37-80.93, p = 0.024.Sarcopenia in LT recipients did not improve in any of the previously sarcopenic patients and newly developed within 1 year in others. Newly developed sarcopenia was associated with increased mortality. Newly developed sarcopenia can be used to stratify patients with regard to the risk of post-LT mortality.

    We evaluated the accuracy of augmented reality (AR)-based navigation assistance through simulation of bone tumours in a pig femur model. We developed an AR-based navigation system for bone tumour resection, which could be used on a tablet PC. To simulate a bone tumour in the pig femur, a cortical window was made in the diaphysis and bone cement was inserted. A total of 133 pig femurs were used and tumour resection was simulated with AR-assisted resection (164 resection in 82 femurs, half by an orthropaedic oncology expert and half by an orthopaedic resident) and resection with the conventional method (82 resection in 41 femurs). In the conventional group, resection was performed after measuring the distance from the edge of the condyle to the expected resection margin with a ruler as per routine clinical practice. The mean error of 164 resections in 82 femurs in the AR group was 1.71 mm (0 to 6). The mean error of 82 resections in 41 femurs in the conventional resection group was 2.64 mm (0 to 11) (p Augmented reality in bone tumour resection: An experimental study.

    The purpose of this work was to compare measured and estimated volumetry prior to liver resection. Data for consecutive patients submitted to major liver resection for colorectal liver metastases at two centres during 2004-2012 were reviewed. All patients underwent volumetric analysis to define the measured total liver volume (mTLV) and measured future liver remnant ratio (mR(FLR)). The estimated total liver volume (eTLV) standardized to body surface area and estimated future liver remnant ratio (eR(FLR)) were calculated. Descriptive statistics were generated and compared. A difference between mR(FLR) and eR(FLR) of ±5% was considered clinically relevant. Data for a total of 116 patients were included. All patients underwent major resection and 51% underwent portal vein embolization. The mean difference between mTLV and eTLV was 157 ml (P < 0.0001), whereas the mean difference between mR(FLR) and eR(FLR) was -1.7% (P = 0.013). By linear regression, eTLV was only moderately predictive of mTLV (R(2) = 0.35). The distribution of differences between mR(FLR) and eR(FLR) demonstrated that the formula over- or underestimated mR(FLR) by ≥5% in 31.9% of patients. Measured and estimated volumetry yielded differences in the FLR of ≥5% in almost one-third of patients, potentially affecting clinical decision making. Estimated volumetry should be used cautiously and cannot be recommended for general use. © 2015 International Hepato-Pancreato-Biliary Association.

    Endoscopic mucosal resection (EMR) has emerged for evaluation and treatment of esophageal nodules. We report our initial experience with EMR for T staging and management of early esophageal cancer. We reviewed patients undergoing EMR for esophageal adenocarcinoma between 2008 and 2013. The primary outcome measure was needed for esophagectomy. Secondary outcomes included complete eradication of adenocarcinoma, recurrence or persistence of cancer, nodal status for those undergoing esophagectomy, and complications of endoscopic treatment. During the study period, 24 patients underwent EMR demonstrating carcinoma, and a grossly margin negative endoscopic resection was achieved in all cases. Ten patients (42 %) had evidence of submucosal invasion and were referred for esophagectomy. Patients with margin negative EMR (n = 10, 42 %) or positive radial margins (n = 4, 16 %) underwent endoscopic surveillance and treatment with radiofrequency ablation or repeat EMR as needed. Thirteen patients (93 %) with intramucosal cancer (IMC) have been successfully managed with ongoing endoscopic surveillance and treatment with a median follow-up of 15.5 months. One patient underwent esophagectomy due to recurrent IMC in the setting of long-segment multifocal high-grade dysplasia. There were no esophageal perforations, one patient developed a self-limited gastrointestinal hemorrhage following EMR, and one had an esophageal stricture following endoscopic management. IMC can be successfully managed endoscopically and thus esophagectomy is avoided in a significant proportion of patients. Endoscopic management may be utilized in the setting of complete resection or radial margin involvement without evidence of submucosal invasion. Close endoscopic follow-up is of paramount importance even in those with negative margins, because recurrent disease may occur following EMR in these patients.

    Surgical therapies for hepatocellular carcinoma (HCC) represent the potentially curative approaches and provide patients the greatest survival advantage. We sought to examine the outcomes of patients with HCC treated with surgical resection, transplantation, and local ablation. The Surveillance, Epidemiology, and End Results database was queried for all patients with nonmetastatic HCC from 2004 to 2007 who underwent local ablation (LA), segmental resection (SR), hemihepatectomy or extended resection (ER), or transplantation (TP). Of 16,209 patients with HCC, 3,989 (24.6 %) met criteria for inclusion and received therapies: 1,550 LA (39 %), 703 SR (18 %), 619 ER (16 %), and 1,117 TP (28 %). AFP was elevated in 69 % (2,026 of 2,921), and fibrosis grade 0-4 was noted in 32 % (368 of 1,156). The 3-year survival by procedure was 34 % (LA), 50 % (SR), 54 % (ER), and 74 % (TP), p = .001. In patients with minimal fibrosis, 1-year survival for patients undergoing resection was similar to TP (85 vs. 92 %, p = .346), but greater than LA (69 %, p = .001). Survival after surgical resection for HCC patients without extensive fibrosis appears to be superior to ablation and non-inferior to transplantation. In an era of organ shortage, transplantation may be better reserved for patients with cirrhosis and/or unresectable disease.

    Considering the epileptogenic effect of cavernoma-surrounding hemosiderin, assumptions are made that resection only of the cavernoma itself may not be sufficient as treatment of symptomatic epilepsy in patients with cavernous malformations. The purpose of this study was to test the hypothesis whether seizure outcome after removal of cavernous malformations may be related to the extent of resection of surrounding hemosiderin-stained brain tissue. In this retrospective study, 31 consecutive patients with pharmacotherapy-refractory epilepsy due to a cavernous malformation were included. In all patients, cavernomas were resected, and all patients underwent pre- and postoperative magnetic resonance imaging (MRI). We grouped patients according to MRI findings (hemosiderin completely removed versus not/partially removed) and compared seizure outcome (as assessed by the Engel Outcome Classification score) between the two groups. Three years after resection of cavernomas, patients in whom hemosiderin-stained brain tissue had been removed completely had a better chance for a favorable long-term seizure outcome compared with those with detectable postoperative hemosiderin (p=0.037). Our study suggests that complete removal of cavernoma-surrounding hemosiderin-stained brain tissue may improve epileptic outcome after resection of cavernous malformations.

    Objective To determine the effects of exogenous glucagon-like peptide-2 (GLP-2), with or without massive distal bowel resection, on adaptation of jejunal mucosa, enteric neurons, gut hormones and tissue reserves in rats. Background GLP-2 is a gut hormone known to be trophic for small bowel mucosa, and to mimic intestinal adaptation in short bowel syndrome (SBS). However, the effects of exogenous GLP-2 and SBS on enteric neurons are unclear. Methods Sprague Dawley rats were randomized to four treatments: Transected Bowel (TB) (n = 8), TB + GLP-2 (2.5 nmol/kg/h, n = 8), SBS (n = 5), or SBS + GLP-2 (2.5 nmol/kg/h, n = 9). SBS groups underwent a 60% jejunoileal resection with cecectomy and jejunocolic anastomosis. All rats were maintained on parenteral nutrition for 7 d. Parameters measured included gut morphometry, qPCR for hexose transporter (SGLT-1, GLUT-2, GLUT-5) and GLP-2 receptor mRNA, whole mount immunohistochemistry for neurons (HuC/D, VIP, nNOS), plasma glucose, gut hormones, and body composition. Results Resection increased the proportion of nNOS immunopositive myenteric neurons, intestinal muscularis propria thickness and crypt cell proliferation, which were not recapitulated by GLP-2 therapy. Exogenous GLP-2 increased jejunal mucosal surface area without affecting enteric VIP or nNOS neuronal immunopositivity, attenuated resection-induced reductions in jejunal hexose transporter abundance (SGLT-1, GLUT-2), increased plasma amylin and decreased peptide YY concentrations.

    Full Text Available To determine the effects of exogenous glucagon-like peptide-2 (GLP-2, with or without massive distal bowel resection, on adaptation of jejunal mucosa, enteric neurons, gut hormones and tissue reserves in rats.GLP-2 is a gut hormone known to be trophic for small bowel mucosa, and to mimic intestinal adaptation in short bowel syndrome (SBS. However, the effects of exogenous GLP-2 and SBS on enteric neurons are unclear.Sprague Dawley rats were randomized to four treatments: Transected Bowel (TB (n = 8, TB + GLP-2 (2.5 nmol/kg/h, n = 8, SBS (n = 5, or SBS + GLP-2 (2.5 nmol/kg/h, n = 9. SBS groups underwent a 60% jejunoileal resection with cecectomy and jejunocolic anastomosis. All rats were maintained on parenteral nutrition for 7 d. Parameters measured included gut morphometry, qPCR for hexose transporter (SGLT-1, GLUT-2, GLUT-5 and GLP-2 receptor mRNA, whole mount immunohistochemistry for neurons (HuC/D, VIP, nNOS, plasma glucose, gut hormones, and body composition.Resection increased the proportion of nNOS immunopositive myenteric neurons, intestinal muscularis propria thickness and crypt cell proliferation, which were not recapitulated by GLP-2 therapy. Exogenous GLP-2 increased jejunal mucosal surface area without affecting enteric VIP or nNOS neuronal immunopositivity, attenuated resection-induced reductions in jejunal hexose transporter abundance (SGLT-1, GLUT-2, increased plasma amylin and decreased peptide YY concentrations. Exogenous GLP-2 attenuated resection-induced increases in blood glucose and body fat loss.Exogenous GLP-2 stimulates jejunal adaptation independent of enteric neuronal VIP or nNOS changes, and has divergent effects on plasma amylin and peptide YY concentrations.

    Perforated colonic diverticulitis usually requires surgical resection, which is associated with significant morbidity. Cohort studies have suggested that laparoscopic lavage may treat perforated diverticulitis with less morbidity than resection procedures. To compare the outcomes from laparoscopic lavage with those for colon resection for perforated diverticulitis. Multicenter, randomized clinical superiority trial recruiting participants from 21 centers in Sweden and Norway from February 2010 to June 2014. The last patient follow-up was in December 2014 and final review and verification of the medical records was assessed in March 2015. Patients with suspected perforated diverticulitis, a clinical indication for emergency surgery, and free air on an abdominal computed tomography scan were eligible. Of 509 patients screened, 415 were eligible and 199 were enrolled. Patients were assigned to undergo laparoscopic peritoneal lavage (n = 101) or colon resection (n = 98) based on a computer-generated, center-stratified block randomization. All patients with fecal peritonitis (15 patients in the laparoscopic peritoneal lavage group vs 13 in the colon resection group) underwent colon resection. Patients with a pathology requiring treatment beyond that necessary for perforated diverticulitis (12 in the laparoscopic lavage group vs 13 in the colon resection group) were also excluded from the protocol operations and treated as required for the pathology encountered. The primary outcome was severe postoperative complications (Clavien-Dindo score >IIIa) within 90 days. Secondary outcomes included other postoperative complications, reoperations, length of operating time, length of postoperative hospital stay, and quality of life. The primary outcome was observed in 31 of 101 patients (30.7%) in the laparoscopic lavage group and 25 of 96 patients (26.0%) in the colon resection group (difference, 4.7% [95% CI, -7.9% to 17.0%]; P = .53). Mortality at 90 days did not

    Purpose: Neural progenitor cells in the subventricular zone (SVZ) have a controversial role in glioblastoma multiforme (GBM) as potential tumor-initiating cells. The purpose of this study was to examine the relationship between radiation dose to the SVZ and survival in GBM patients. Methods and Materials: The study included 116 patients with primary GBM treated at the Johns Hopkins Hospital between 2006 and 2009. All patients underwent surgical resection followed by adjuvant radiation therapy with intensity modulated radiation therapy (60 Gy/30 fractions) and concomitant temozolomide. Ipsilateral, contralateral, and bilateral SVZs were contoured on treatment plans by use of coregistered magnetic resonance imaging and computed tomography. Multivariate Cox regression was used to examine the relationship between mean SVZ dose and progression-free survival (PFS), as well as overall survival (OS). Age, Karnofsky Performance Status score, and extent of resection were used as covariates. The median age was 58 years (range, 29-80 years). Results: Of the patients, 12% underwent biopsy, 53% had subtotal resection (STR), and 35% had gross total resection (GTR). The Karnofsky Performance Status score was less than 90 in 54 patients and was 90 or greater in 62 patients. The median ipsilateral, contralateral, and bilateral mean SVZ doses were 48.7 Gy, 34.4 Gy, and 41.5 Gy, respectively. Among patients who underwent GTR, a mean ipsilateral SVZ dose of 40 Gy or greater was associated with a significantly improved PFS compared with patients who received less than 40 Gy (15.1 months vs 10.3 months; P=.028; hazard ratio, 0.385 [95% confidence interval, 0.165-0.901]) but not in patients undergoing STR or biopsy. The subgroup of GTR patients who received an ipsilateral dose of 40 Gy or greater also had a significantly improved OS (17.5 months vs 15.6 months; P=.027; hazard ratio, 0.385 [95% confidence interval, 0.165-0.895]). No association was found between SVZ radiation dose and PFS

    Minimally invasive thymectomy (MIT) is a surgical approach to thymectomy that has more favorable short-term outcomes for myasthenia gravis than open thymectomy (OT). The oncologic outcomes of MIT performed for thymoma have not been rigorously evaluated. We analyzed determinants of complete (R0) resection among patients undergoing MIT and OT in a large international database. The retrospective database of the International Thymic Malignancy Interest Group was queried. Chi-square and Wilcoxon rank sum tests, multivariate logistic regression models, and propensity matching were performed. A total of 2514 patients underwent thymectomy for thymoma between 1997 and 2012; 2053 of them (82%) underwent OT and 461 (18%) underwent MIT, with the use of MIT increasing significantly in recent years. The rate of R0 resection among patients undergoing OT was 86%, and among those undergoing MIT it was 94% (p thymoma has been increasing substantially over time, and MIT can achieve rates of R0 resection for thymoma similar to those achieved with OT.

    1995-01-01

    Purpose: To determine if preoperative radiation therapy allows sphincter preservation in the treatment of rectal cancer. Methods and Materials: Thirty patients with the diagnosis of invasive, resectable, primary adenocarcinoma of the rectum limited to the pelvis were enrolled on a Phase I/II trial of preoperative radiation therapy plus low anterior resection/coloanal anastomosis. By preoperative assessment, all patients had invasive tumors (2: T2, 28: T3) involving the distal half of the rectum and required an abdominoperineal resection. The median tumor size was 4 cm (range: 1.5-6 cm) and the median distance from the anal verge was 4 cm (range: 3-7 cm). The whole pelvis received 46.8 Gy followed by a 3.60 Gy boost to the primary tumor bed. The median follow-up was 43 months (range: 6-82 months). Results: Of the 29 patients who underwent resection, 3 (10%) had a complete pathologic response and 24 (83%) were able to successfully undergo a low anterior resection/coloanal anastomosis. The incidence of local failure was crude: 17% and 4-year actuarial: 23%. The 4-year actuarial survival was 75%. One patient developed a partial disruption of the anastomosis and two developed rectal stenosis. Analysis of sphincter function using a previously published scale was performed at the time of last follow-up in 22 of the 24 patients who underwent a low anterior resection/coloanal anastomosis. Function was good or excellent in 77%. The median number of bowel movements/day was two (range: 1-6). Conclusions: This technique may be an alternative to an abdominoperineal resection in selected patients. Continued follow-up is needed to determine if this approach ultimately has similar local control and survival rates as an abdominoperineal resection

    Demidov, V.P.; Bityutskij, P.G.; Sorokina, N.A.; Kozhanov, L.G. (Akademiya Meditsinskikh Nauk SSSR, Moscow. Inst. Onkologii)

    A study was made of an X-ray picture of the larynx and the state of the pharyngoesophageal anastomosis after salvage operations in 72 patients. Horizontal resection was performed in 42 patients, frontal-lateral in 27 and reconstructive laryngectomy in 3. An analysis of clinicoroentgenological changes showed that their nature depended on the type of resection and the area of resected anatomical structures and elements in the larynx as well as on concomitant manifestations of tumor recurrence or inflammatory disorders. Accurate data on resection type and the area of resectable laryngeal structures are indispensable in assessing X-ray changes.

    Circumferential resection margin (CRM) involvement (R1) is used to audit rectal cancer surgical quality. However, when downsizing chemoradiation (dCRT) is used, CRM audits both dCRT and surgery, its use reflecting a high casemix of locally advanced tumours. We aimed to evaluate predictors of R1 and benchmark R1 rates in the dCRT era, and to assess the influence of failure of steps in the multidisciplinary team (MDT) process to CRM involvement. A retrospective analysis of prospectively collected rectal cancer data was undertaken. Patients were classified according to CRM status. Uni- and multivariate analysis was undertaken of risk factors for R1 resection. The contribution of the steps of the MDT process to CRM involvement was assessed. Two hundred and ten rectal cancers were evaluated (68% T3 or T4 on preoperative staging). R1 (microscopic) and R2 (macroscopic) resections occurred in 20 (10%) and 6 patients (3%), respectively. Of several factors associated with R1 resections on univariate analysis, only total mesorectal excision (TME) specimen defects and threatened/involved CRM on preoperative imaging remained as independent predictors of R1 resections on multivariate analysis. Causes of R1 failure by MDT step classification found that less than half were associated with and only 15% solely attributable to a suboptimal TME specimen. Total mesorectal excision specimen defects and staging-predicted threatened or involved CRM are independent strong predictors of R1 resections. In most R1 resections, the TME specimen was intact. It is important to remember the contribution of both the local staging casemix and dCRT failure when using R1 rates to assess purely surgical competence.

    Lung cancer is localized in the upper lobes in more than half of the cases. The risk of tumor infiltration of centrally located structures, such as bronchi and vessels are enhanced due to the anatomic topography. Pneumonectomy competes with sleeve resection for the surgical resection of centrally located tumors. The present review deals with the question if pneumonectomy should be considered as an alternative to sleeve resection for the treatment of lung cancer. Primary pneumonectomy does not provide any advantage even in advanced nodal disease. Extended lymph node dissection is not a contraindication for sleeve resections. Local recurrence rate is lower after sleeve resections despite the same radicality for both surgical treatment options. Mortality and morbidity rates are significantly lower for sleeve resections. Sleeve resections are associated with prolonged survival and better quality of life even in elderly patients.

    Discussion: The patient required only physical therapy and oral prednisone following surgery for treatment of the neuropraxia. She responded well and has regained significant neuromotor function of the affected limb. Cases presenting with post-resection neurological sequelae without any known intraoperative nerve injury may respond very well to conservative treatment. Hence, it is very important to collaborate with Neurology and Physical Therapy to achieve best possible outcome.

    Full Text Available Introduction: Surgical treatment of malignant thoracic wall tumors represents a formidable challenge. In particular, locally advanced tumors that have already infiltrated critical anatomic structures are associated with a high surgical morbidity and can result in full thickness defects of the thoracic wall. Plastic surgery can reduce this surgical morbidity by reconstructing the thoracic wall through various tissue transfer techniques. Sufficient soft tissue reconstruction of the thoracic wall improves life quality and mitigates functional impairment after extensive resection. The aim of this article is to illustrate the various plastic surgery treatment options in the multimodal therapy of patients with malignant thoracic wall tumors.Material und methods: This article is based on a review of the current literature and the evaluation of a patient database.Results: Several plastic surgical treatment options can be implemented in the curative and palliative therapy of patients with malignant solid tumors of the chest wall. Large soft tissue defects after tumor resection can be covered by local, pedicled or free flaps. In cases of large full-thickness defects, flaps can be combined with polypropylene mesh to improve chest wall stability and to maintain pulmonary function. The success of modern medicine has resulted in an increasing number of patients with prolonged survival suffering from locally advanced tumors that can be painful, malodorous or prone to bleeding. Resection of these tumors followed by thoracic wall reconstruction with viable tissue can substantially enhance the life quality of these patients. Discussion: In curative treatment regimens, chest wall reconstruction enables complete resection of locally advanced tumors and subsequent adjuvant radiotherapy. In palliative disease treatment, stadium plastic surgical techniques of thoracic wall reconstruction provide palliation of tumor-associated morbidity and can therefore improve

    Jan Plzák

    Full Text Available OBJECTIVES: Access to the pterygopalatine fossa is very difficult due to its complex anatomy. Therefore, an open approach is traditionally used, but morbidity is unavoidable. To overcome this problem, an endoscopic endonasal approach was developed as a minimally invasive procedure. The surgical aim of the present study was to evaluate the utility of the endoscopic endonasal approach for the management of both benign and malignant tumors of the pterygopalatine fossa. METHOD: We report our experience with the endoscopic endonasal approach for the management of both benign and malignant tumors and summarize recent recommendations. A total of 13 patients underwent surgery via the endoscopic endonasal approach for pterygopalatine fossa masses from 2014 to 2016. This case group consisted of 12 benign tumors (10 juvenile nasopharyngeal angiofibromas and two schwannomas and one malignant tumor. RESULTS: No recurrent tumor developed during the follow-up period. One residual tumor (juvenile nasopharyngeal angiofibroma that remained in the cavernous sinus was stable. There were no significant complications. Typical sequelae included hypesthesia of the maxillary nerve, trismus, and dry eye syndrome. CONCLUSION: The low frequency of complications together with the high efficacy of resection support the use of the endoscopic endonasal approach as a feasible, safe, and beneficial technique for the management of masses in the pterygopalatine fossa.

    Anoopa A. Koshy MD

    2013-01-01

    Full Text Available A 56-year-old woman presented to our clinic for recurrent hypoglycemia after undergoing resection of an incidentally discovered nonfunctional pancreatic endocrine tumor 6 years ago. She underwent a distal pancreatectomy and splenectomy, after which she developed diabetes and was placed on an insulin pump. Pathology showed a pancreatic endocrine neoplasm with negative islet hormone immunostains. Two years later, computed tomography scan of the abdomen showed multiple liver lesions. Biopsy of a liver lesion showed a well-differentiated neuroendocrine neoplasm, consistent with pancreatic origin. Six years later, she presented to clinic with 1.5 years of recurrent hypoglycemia. Laboratory results showed elevated proinsulin, insulin levels, and c-peptide levels during a hypoglycemic episode. Computed tomography scan of the abdomen redemonstrated multiple liver lesions. Repeated transarterial catheter chemoembolization and microwave thermal ablation controlled hypoglycemia. The unusual features of interest of this case include the transformation of nonfunctioning pancreatic endocrine tumor to a metastatic insulinoma and the occurrence of atrial flutter after octreotide for treatment.

    Recurrent ulceration following gastrectomy for peptic ulcer disease typically occurs within the first several years postoperatively. Since 1990, we have managed 20 patients who had undergone previous gastrectomy for peptic ulcer and developed ulcer recurrence more than 10 years postoperatively. Mean age at recurrence was 64 years, and the average time from original surgery to recurrent ulceration was 21 years (range, 10-36 years). All patients had undergone vagotomy and antrectomy (17 patients) or subtotal gastrectomy (3 patients). Presenting symptoms included gastric outlet obstruction (70%) and bezoar formation (60%). Endoscopic findings in this group of patients included a stenotic gastric outlet (70%) and marginal ulcerations (80%). Thirteen of 15 patients tested (87%) were Helicobacter pylori positive. Reoperation included partial resection of the gastric pouch and exploration for persistent vagus nerve. Twelve patients underwent Roux-en-Y reconstruction, whereas eight patients had Bilroth II reconstruction. Three of the latter group also had Braun enteroenterostomy performed. Good to excellent clinical results were obtained in 80 per cent of patients. The four patients with poor outcomes shared the following characteristics: 1) H. pylori-positive status, 2) presence of a preoperative bezoar, 3) Roux-en-Y reconstruction. Our current approach is to avoid Roux-en-Y construction in favor of Braun enteroenterostomy. Further prospective analysis of long-term postgastrectomy patients is needed to determine whether this clinical picture represents a new postgastrectomy syndrome.

    Myxomas are the most common benign cardiac tumors, which are considered emergency surgery. The resection should not be delayed because 8-9% of affected patients may die due to intracardiac blood flow obstruction. We presente a clinical case of a 47 year old female, history of dyslipidemia. Disease starts with retrosternal oppression feeling, dyspnea on moderate exercise, dizziness, pain in joints hands. Arrhytmic heart sounds, diastolic mitral murmur II/IV, breth sounds present, no lymph. Laboratory: hemoglobin 11.0, leucocyte 9000, glucose 96 mg/dL, chest RX medium arch prominence cardiac silhouette. ECO transthoracic LVEF 60 %, with left atrial intracardiac tumor 13x11 cm, pedicle fixed the interatrial septum, the mitral valve bulges, with mild mitral valve. Half sternotomy is performed intracardiac tumor resection, pericardial placement interatrial with extracorporeal circulation support 65', aortic clamping time of 40'. Intracardiac tumor surgical findings interatrial septum fixed to left side, pedicle, rounded, yellow, multiloculated, soft, 13x10 cm in diameter. Histopathological diagnosis cardiac myxoma. We conclude that the tumor resection was carried in a timely manner with satisfactory evolution.

    Transient vision loss after major surgical procedures is a rare clinical complication. The most common etiologies are cardiac, spinal, head, and neck surgeries. There has been no report on vision loss after lung resection. A 65-year-old man was admitted to our clinic with lung cancer. Resection was performed using right upper lobectomy with no complications. Cortical blindness developed 12 hours later in the postoperative period. Results from magnetic resonance imaging and diffusion-weighted investigations were normal. The neurologic examination was normal. The blood glucose level was 92 mg/dL and blood gas analysis showed a PO 2 of 82 mm Hg. After 24 hours, the patient began to see and could count fingers, and his vision was fully restored within 72 hours after this point. Autonomic dysfunction due to impaired microvascular structures in diabetes mellitus may induce posterior circulation dysfunction, even when the hemodynamic state is normal in the perioperative period. The physician must keep in mind that vision loss may occur after lung resection due to autonomic dysfunction, especially in older patients with diabetes mellitus. PMID:28824977

    The influence of EGFR pathway mutations on cetuximab-containing rectal cancer preoperative chemoradiation (CRT) is uncertain. In a prospective phase II trial (EXCITE), patients with magnetic resonance imaging (MRI)-defined non-metastatic rectal adenocarinoma threatening/involving the surgical resection plane received pelvic radiotherapy with concurrent capecitabine, irinotecan and cetuximab. Resection was recommended 8 weeks later. The primary endpoint was histopathologically clear (R0) resection margin. Pre-planned retrospective DNA pyrosequencing (PS) and next generation sequencing (NGS) of KRAS, NRAS, PIK3CA and BRAF was performed on the pre-treatment biopsy and resected specimen. Eighty-two patients were recruited and 76 underwent surgery, with R0 resection in 67 (82%, 90%CI: 73-88%) (four patients with clinical complete response declined surgery). Twenty-four patients (30%) had an excellent clinical or pathological response (ECPR). Using NGS 24 (46%) of 52 matched biopsies/resections were discrepant: ten patients (19%) gained 13 new resection mutations compared to biopsy (12 KRAS, one PIK3CA) and 18 (35%) lost 22 mutations (15 KRAS, 7 PIK3CA). Tumours only ever testing RAS wild-type had significantly greater ECPR than tumours with either biopsy or resection RAS mutations (14/29 [48%] vs 10/51 [20%], P=0.008), with a trend towards increased overall survival (HR 0.23, 95% CI 0.05-1.03, P=0.055). This regimen was feasible and the primary study endpoint was met. For the first time using pre-operative rectal CRT, emergence of clinically important new resection mutations is described, likely reflecting intratumoural heterogeneity manifesting either as treatment-driven selective clonal expansion or a geographical biopsy sampling miss.

    Full Text Available Abstract Background Radiofrequency ablation (RFA is a thermal energy delivery system used for coagulative cellular destruction of small tumors through percutaneous or intraoperative application of its needle electrode to the target area, and for assisting partial resection of liver and kidney. We tried to evaluate the regional oxidative and pre-inflammatory stress of RFA-assisted wedge lung resection, by measuring the MDA and tumor Necrosis Factor Alpha (TNF-α concentration in the resected lung tissue of a swine model. Method Fourteen white male swines, divided in two groups, the RFA-group and the control group (C-group underwent a small left thoracotomy and wedge lung resection of the lingula. The wedge resection in the RFA-group was performed using the RFA technique whereas in C-group the simple "cut and sew" method was performed. We measured the malondialdehyde (MDA and TNF-α concentration in the resected lung tissue of both groups. Results In C-group the MDA mean deviation rate was 113 ± 42.6 whereas in RFA-group the MDA mean deviation rate was significantly higher 353 ± 184 (p = 0.006. A statistically significant increase in TNF-α levels was also observed in the RFA-group (5.25 ± 1.36 compared to C-group (mean ± SD = 8.48 ± 2.82 (p = 0.006. Conclusion Our data indicate that RFA-assisted wedge lung resection in a swine model increases regional MDA and TNF-a factors affecting by this oxidative and pre-inflammatory stress of the procedure. Although RFA-assisted liver resection can be well tolerated in humans, the possible use of this method to the lung has to be further investigated in terms of regional and systemic reactions and the feasibility of performing larger lung resections.

    A duodenum-preserving pancreatic head resection (DPPHR) was first reported by Beger et al. in 1980. However, its application has been limited to chronic pancreatitis because of it is a subtotal pancreatic head resection. In 1990, we reported duodenum-preserving total pancreatic head resection (DPTPHR) in 26 cases. This opened the way for total pancreatic head resection, expanding the application of this approach to tumorigenic morbidities such as intraductal papillary mucinous tumor (IMPT), other benign tumors, and small pancreatic cancers. On the other hand, Nakao et al. reported pancreatic head resection with segmental duodenectomy (PHRSD) as an alternative pylorus-preserving pancreatoduodenectomy technique in 24 cases. Hirata et al. also reported this technique as a new pylorus-preserving pancreatoduodenostomy with increased vessel preservation. When performing DPTPHR, the surgeon should ensure adequate duodenal blood supply. Avoidance of duodenal ischemia is very important in this operation, and thus it is necessary to maintain blood flow in the posterior pancreatoduodenal artery and to preserve the mesoduodenal vessels. Postoperative pancreatic functional tests reveal that DPTPHR is superior to PPPD, including PHSRD, because the entire duodenum and duodenal integrity is very important for postoperative pancreatic function.

    Metastatic adrenocortical carcinoma (ACC) is rapidly fatal, with few options for treatment. Patients with metachronous recurrence may benefit from surgical resection. The survival benefit in patients with hematogenous metastasis at initial presentation is unknown. A review of all patients undergoing surgery (European Network for the Study of Adrenal Tumors) stage IV ACC between January 2000 and December 2012 from two referral centers was performed. Kaplan-Meier estimates were analyzed for disease-free and overall survival (OS). We identified 27 patients undergoing surgery for stage IV ACC. Metastases were present in the lung (19), liver (11), and brain (1). A complete resection (R0) was achieved in 11 patients. The median OS was improved in patients undergoing R0 versus R2 resection (860 vs. 390 days; p = 0.02). The 1- and 2-year OS was also improved in patients undergoing R0 versus R2 resection (69.9 %, 46.9 % vs. 53.0 %, 22.1 %; p = 0.02). Patients undergoing neoadjuvant therapy (eight patients) had a trend towards improved survival at 1, 2, and 5 years versus no neoadjuvant therapy (18 patients) [83.3 %, 62.5 %, 41.7 % vs. 56.8 %, 26.6 %, 8.9 %; p = 0.1]. Adjuvant therapy was associated with improved recurrence-free survival at 6 months and 1 year (67 %, 33 % vs. 40 %, 20 %; p = 0.04) but not improved OS (p = 0.63). Sex (p = 0.13), age (p = 0.95), and location of metastasis (lung, p = 0.51; liver, p = 0.67) did not correlate with OS after operative intervention. Symptoms of hormonal excess improved in 86 % of patients. Operative intervention, especially when an R0 resection can be achieved, following systemic therapy may improve outcomes, including OS, in select patients with stage IV ACC. Response to neoadjuvant chemotherapy may be of use in defining which patients may benefit from surgical intervention. Adjuvant therapy was associated with decreased recurrence but did not improve OS.

    The fate of suboptimal anastomosis is unknown and early detection of anastomotic leakage after colon resection is crucial for the proper management of patients. Twenty-six rats were assigned to "Control", "Leakage" and "Suboptimal anastomosis" groups where they underwent either sham laparotomy, cecal ligation, and puncture or anastomosis with four sutures following colon resection, respectively. At the fifth hour and on the third and ninth days; peripheral blood and peritoneal washing samples through relaparotomy were obtained. The abdomen was inspected macroscopically for anastomotic healing. Polymerase chain reaction (PCR) with 16s rRNA and E.coli-specific primers were run on all samples along with aerobic and anaerobic cultures. The sensitivity and specificity of PCR on different bodily fluids with 16s rRNA and E.coli-specific primers were 100% and 78%, respectively. All samples of peritoneal washing fluids on the third and ninth days showed presence of bacteria in both PCR and culture. The inspection of the abdomen revealed signs of anastomotic leakage in eight rats (80%), whereas mortality related with anastomosis was detected in two (20%). Anastomotic leakage with suboptimal anastomosis after colon resection is high and the early detection is possible by running PCR on peritoneal samples as early as 72 hours.

    The objectives of this study were to evaluate blood and abdominal fluid lactate and glucose, fluid cytology, culture, and volume 24 and 48 hr following intestinal resection and anastomosis in dogs with and without closed-suction drains and to correlate findings with survival. Thirty-five client-owned dogs that underwent intestinal resection and anastomosis were prospectively enrolled in the study. Abdominal fluid was submitted for culture at surgery and again 24 hr postoperatively. Twenty-four and 48 hr postoperatively, blood and abdominal fluid glucose and lactate were measured and fluid was submitted for cytology. Abdominal fluid was collected either from a closed-suction drain or by abdominocentesis. Patients were followed either for 14 days or until death. Comparisons were made based on development of dehiscence and presence or absence of a drain. Patients with dehiscence were more likely to have positive cultures at 24 hr and to have had more bowel resected. Surviving patients without drains had significantly smaller differences in blood and fluid glucose and lactate both 24 and 48 hr postoperatively than surviving patients with drains. The significant differences identified between patients with and without drains suggests a need for further research into the effect of drains on abdominal fluid values.

  18. Mucociliary clearance following tracheal resection and end-to-end anastomosis.

    Mucociliary clearance is an important cleaning system of the bronchial tree. The complex transport system reacts sensitively to medicinal stimuli and inhaled substances. A disturbance causes secretion retention which encourages the development of acute and chronic pulmonary diseases. It is not yet known in which way sectional resection of the central airway effects mucociliary clearance. A large number of the surgical failures are attributable to septic complications in the area of the anastomosis. In order to study the transportation process over the anastomosis, ten dogs underwent a tracheal resection with end-to-end anastomosis, and the mucociliary activity was recorded using a bronchoscopic video-technical method. Recommencement of mucous transport was observed on the third, and transport over the anastomosis from the sixth to tenth, postoperative days. The mucociliary clearance had completely recovered on the twenty-first day in the majority of dogs. Histological examination of the anastomoses nine months postoperatively showed a flat substitute epithelium without cilia-bearing cells in all dogs. This contrasts with the quick restitution of the transport function. In case of undamaged respiratory mucosa, a good adaptation of the resection margins suffices for the mucous film to slide over the anastomosis.

    Primary cardiac tumors are rare and myxoma constitutes the majority. The present study summarizes our 30-year clinical outcomes of surgical myxoma resection. Between January 1986 and December 2015, 93 patients (30 men, 63 women; mean age, 54.7 ± 16.6 years) underwent surgical myxoma resection. The most common origin site was the left atrium. Surgery was performed via a biatrial approach in 74.2%, atrial septotomy through right atriotomy in 17.2%, and left atriotomy only in 8.6%. Mean myxoma size based on longest length was 4.73 ± 1.92 cm (range, 1.2-11.0 cm). The mean follow-up duration was 9.9 ± 7.8 years (range, 0-29 years). In-hospital mortality was 3.2%. The most common postoperative complication was atrial fibrillation (4.3%). The 5-, 10-, and 30-year survival rates were 92.9%, 87.2%, and 75.5%, respectively. Recurrence occurred in two patients (2.1%), which were detected at 20 and 79 months after the first surgery, respectively. Long-term survival after myxoma resection was excellent and recurrence was rare. Based on our experience, surgical method did not affect the outcome.

    A 47-year-old woman with a single-nodule hepatic tumor was referred to our hospital. She had no symptoms. The tumor was located at the surface of the right lobe of the liver; it showed peripheral low signal intensity on a magnetic resonance imaging apparent diffusion coefficient (ADC) map, and an influx of blood flow into the peripheral area of the tumor at the early vascular phase on perflubutane microbubble (Sonazoid(®)) contrast-enhanced (CE) ultrasonography. Since we suspected a malignant tumor, the patient underwent surgical resection. The hepatic tumor was resected curatively. Pathological examination revealed that the tumor was composed of epithelioid cells with an epithelioid structure and/or cord-like structure. Immunohistochemical staining was positive for cluster of differentiation 34 and factor VIII-related antigen. Based on the above, a final diagnosis of hepatic epithelioid hemangioendothelioma (EHE) was made. Hepatic EHE is a rare hepatic tumor: only a few cases of hepatic EHE with curative resection have been reported. We were unable to reach a diagnosis of hepatic EHE by imaging studies; however, an ADC map was useful in showing the malignant potential of the tumor, and CE ultrasonography was useful in revealing the peripheral blood flow of the tumor. When an unusual hepatic mass is encountered, hepatic EHE should be kept in mind, and the mass should be inspected with more than one imaging modality, including an ADC map, in the process of differential diagnosis.

    We report a case of repeated surgical resections for the tumor seeding of hepatocellular carcinoma(HCC)after radiofrequency ablation(RFA). A 79-year-old man, who had an intrahepatic recurrence of HCC(segment 2)5 months after RFA, was referred to our hospital for surgery, and underwent a laparoscopic lateral segmentectomy. Histological examination showed a poorly differentiated HCC(pStage II). Eight months after RFA, subcutaneous nodules along the RFA needle tract were pointed out by abdominal CT, and a tumorectomy was performed. Nineteen months after RFA, abdominal CT showed a 33mm tumor on the side of the spleen, leading to the diagnosis of the peritoneal dissemination following RFA. The tumor has been growing up to 49mm in size in spite of a radiation therapy. Accordingly, a laparoscopic tumorectomy was performed 26 months after RFA. His resected tumors were morphologically identical to the intrahepatic recurrence of HCC. The patient had remained recurrence-free for 4 months after the second tumorectomy. Our case demonstrated the utility of surgical resection for the tumor seeding of HCC following RFA.

    Age has been classically considered as a determining factor for the development of postoperative complications related to lung resection for bronchogenic carcinoma. The Postoperative Complications Study Group of the Spanish Society of Thoracic Surgery has promoted a registry to analyze this factor. A total of 3,307 patients who underwent any type of surgical resection for bronchogenic carcinoma have been systematically and prospectively recorded in any of the 24 units that are part of the group. Several variables related to comorbidity and age, as well as postoperative complications, were analyzed. The mean age of patients was 65,44. Men were significantly more common than female. The most frequent complication was prolonged air leak, which was observed in more than one third of patients. In a univariant analysis, air leak presence and postsurgical atelectasis showed statistical association with patient age, when stratified in age groups. In a multivariate analysis, age was recognized as an independent prognostic factor in relation to air leak onset. However, this could not be confirmed for postoperative atelectasis. Age is a predisposing factor for the development of postoperative complications after lung resection. Other associated factors also influence the occurrence of these complications.

    Firstly described in 2002, the robotic liver surgery has not spread widely due to its high cost and the lack of a standardized training program. Still being considered as a 'development in progress' technique, it has however a potential to overcome the traditional limitations of the laparoscopic approach in liver interventions. We analyzed the postoperative outcomes of 10 patients who had undergone robotic partial resection of the caudate lobe (Spiegel lobe) from March 2014 to May 2016 in order to evaluate the advantages of robotic technique in hands of a young surgeon. The mean operative time was 258min (150-522) and the estimated blood loss 137ml (50-359), in none of the cases a blood transfusion was required. No patient underwent a conversion to open surgery; the overall morbidity was 2/10 (20%) and all the complications occurred (biliary fistula and pleural effusion) did not require a surgical revision. At histological examination, the mean tumour size was 2.63cm and we achieved R0-resection rate of 100%. The 90-day mortality rate was null. The 1-year overall and disease free-survival rates were 100% and 80%, respectively. Despite several concerns regarding the cost-effectiveness, a fully robotic partial resection of caudate lobe is an advantageous, implementable technique providing promising short-term postoperative outcomes with acceptable benefit-risk profile.

    To evaluate the oncological safety and pregnant outcomes of fertility-sparing uterine lesion resection in treating gestational trophoblastic neoplasias. After the treatment of surgery and chemotherapy, all the patients achieved complete remission. With a median follow-up time of 44 months (range, 6-188), 3 patients (3.85%) relapsed within 3-26 months. Multivariate analysis showed that tumor size was the independent risk factor of recurrence and the cutoff value was 4.2cm. Among 37 patients who attempted to conceive, 31 achieved clinical pregnancy. The rate of pregnancy and live birth were 83.8% and 77.4%. Uterine rupture did not occurred no matter in cesarean section or vaginal delivery. No congenital abnormalities were reported among the live births. From January 1995 to December 2014, 78 patients with gestational trophoblastic neoplasias who underwent fertility-sparing uterine lesion resection at Peking Union Medical College Hospital were reviewed. The complete remission rate, fertility rate, pregnant outcomes and risk factors of recurrence were analyzed. Fertility-sparing uterine lesion resection might be considered as a safe and reasonable alternative for high-selected young women to remove uterine lesion in the treatment of gestational trophoblastic neoplasias.

    This study retrospectively reviewed 48 cases of gastric submucosal tumors (SMTs) treated by endolumenal endoscopic full-thickness resection (EFR) microsurgery in our gastrointestinal endoscopy center. From November 2009 to October 2012, 48 cases underwent endolumenal EFR for resection of muscularis propria-originating gastric SMTs. Characteristics of the 48 patients, clinical efficacy, safety of EFR, and post-EFR pathological diagnoses were evaluated retrospectively. EFR was successfully performed in 48 cases with 52 lesions. The median operation time was 59.72 minutes (range, 30-270 minutes; standard deviation, 39.72 minutes). The mean tumor size was 1.59 cm (range, 0.50-4.80 cm; standard deviation, 1.01 cm). During the EFR process, dual-channel gastroscopy was applied in 20 cases of SMTs, and paracentesis during the EFR process was applied in 9 cases. EFR for larger SMTs and gastric corpus-originating SMTs had longer operative times. Pathological diagnosis included 43 gastrointestinal stromal tumors, 4 leiomyomas, and 1 schwannoma. A larger tumor size was associated with higher risk of malignancy. No severe postoperative complications were observed. No tumor recurrences were confirmed in follow-up gastroscopy. The endolumenal EFR technique proved to be feasible and minimally invasive, even for the resection of large gastric tumors originating from the muscularis propria. However, more data on EFR must be obtained and analyzed.

    The strategic management of primary lung cancer in patients with poor cardiopulmonary status is still controversial. The aim of this study was to ascertain the early and late results of wide-margin wedge resection with curative intent in this group of patients. Between January 1995 and January 2002, 24 patients (13 males; mean age, 69.96 years) with baseline poor cardiopulmonary status underwent wide-margin wedge resection of preoperatively diagnosed primary lung cancer. All patients suffered from chronic obstructive pulmonary disease and 9 (37.5%) also had symptomatic ischemic heart disease. Eight patients were in New York Heart Association class III and 12 were in class IV. There were no post-operative deaths. Complications included chest infection in 3, surgical emphysema with prolonged air leak in 1, and atrial fibrillation in 6. Overall 7-year survival was 23.3%. Three patients with ischemic heart disease suffered late non-cancer-related death due to myocardial infarction at 48, 60, and 60 months postoperatively. Cancer-free 5-year survival was 54.3%, with 7/24 (29%) late recurrences. Our study suggests that wide-margin wedge resection is a valuable surgical option for primary lung cancer in patients with poor cardiopulmonary status.

    Video-assisted thoracic surgery (VATS) has significantly developed over the last decade. However, a VATS approach for thymoma remains controversial. The aim of this study was to evaluate the feasibility of VATS thymectomy for the treatment of early-stage thymoma and to compare the outcomes with open resection. A comparative study of 59 patients who underwent surgical resection for early stage thymoma (VATS: 44 and open resection: 15) between 1993 and 2011 was performed. Data of patient characteristics, morbidity, mortality, length of hospital stay, the relationship between miasthenia gravis-thymoma, recurrence, and survival were collected for statistical analysis. Thymomas were classified according to Masaoka staging system: 38 in stage I (VATS group: 29 and open group: 9) and 21 in stage II (VATS group: 15 and open group: 6). The mean tumor size in the open group was 7.6cm (13-4cm) and in the VATS group 6.9cm (12-2.5cm). The average length of stay was shorter in the VATS group than in the open group (Pthymoma is technically feasible and is associated with a shorter hospital stay. The 5-year oncologic outcomes were similar in the open and VATS groups. Copyright © 2013 AEC. Publicado por Elsevier España, S.L.U. All rights reserved.

    The management of obstructive left colon cancer (OLCC) remains debatable with the single-stage procedure of primary colonic anastomosis after cancer resection and on-table intracolonic lavage now being supported. Patients with acute OLCC who were admitted between January 2008 and January 2015 were distributed into 5 different groups. Group ICI underwent emergency laparotomy for primary anastomosis following colonic resection and intraoperative colonic lavage; Group HP underwent emergency Hartmann's Procedure; Group CON consisted of patients treated by conservative management with subsequent elective open cancer resection; Group COL were colostomy patients; and Group INT consisted of patients who had interventional radiology followed by open elective colon cancer resection. The demographics of the patients and comorbidity, intraoperative data, and postoperative data were collected, with P  .05). Group INT and Group CON, when compared to the three surgical groups, Groups ICI, Group COL, and Group HP, individually, were statistically significant for the duration of surgery (P anastomosis following colonic resection after irrigation can be safely performed in selected patients, with the necessary surgical expertise, with no increased risk in mortality, anastomotic leakage, and other postoperative complications.

In 18 (75 % patients of Group I and in 14 (77.7 % patients of Group II, total mesorectumectomy(TME was assessed as grade 3 (p=0.83. The frequency of postoperative complications in uLAR-treated group was 20.8 %, not requiring a secondary revision procedure, and 27.8 % in ISR-treated group, requiring repeated surgery. The mean value of the fecal incontinence according to the Wechsler scale in a month after surgery was significantly higher in group II than in Group I patients (9.3 versus 6.2, р=0.01. The average treatment cost for uLAR was higher by 45,000 rubles than that for ISR. Conclusion. Both surgical procedures were matched by the duration of operation, amount of blood loss and the quality of mesorectumectomy. The complication rate was not significantly different between two groups, however, 16.8 % of Group II patients required relaparotomy, likely due to the mastering of the ISR technique. Ultra-low anterior resections of the rectum are functionally preferred. When performing ISR, the technique of reservoir colo-anal anastomosis with preservation of the portion of the internal sphincter provides functional results comparable with those obtained using LAR.

    Navigated transcranial magnetic stimulation (nTMS) helps to determine the distribution of motor eloquent areas prior to brain surgery. Yet, the eloquence of primary motor areas frontal to the precentral gyrus identified via nTMS is unclear. To investigate the resection of nTMS-positive prerolandic motor areas and its correlation with postsurgical impairment of motor function. Forty-three patients with rolandic or prerolandic gliomas (WHO grade I-IV) underwent nTMS prior to surgery. Only patients without ischemia within the motor system in postoperative MRI diffusion sequences were enrolled. Based on the 3-dimensional fusion of preoperative nTMS motor mapping data with postsurgical MRI scans, we identified nTMS points that were resected in the infiltration zone of the tumor. We then classified the resected points according to the localization and latency of their motor evoked potentials. Surgery-related paresis was graded as transient (≤6 weeks) or permanent (>6 weeks). Out of 43, 31 patients (72%) showed nTMS-positive motor points in the prerolandic gyri. In general, 13 out of 43 patients (30%) underwent resection of nTMS points. Ten out of these patients showed postoperative paresis. There were 2 (15%) patients with a transient and 8 (62%) with a permanent surgery-related paresis. In 3 cases (23%), motor function remained unimpaired. After resection of nTMS-positive motor points, 62% of patients suffered from a new permanent paresis. Thus, even though they are located in the superior or middle frontal gyrus, these cortical areas must undergo intraoperative mapping. Copyright © 2017 by the Congress of Neurological Surgeons.

    The management of non-small cell lung cancer (NSCLC) depends on the stage, with a satellite nodule in the same lobe being classified as T4 stage IIIB even in node negative patients. Controversy exists as to the optimal management of these patients. Our objectives were to evaluate the outcomes in surgically resected patients with a T4 satellite lesion and to analyze the prognostic factors associated with outcome. Patients who underwent resection for T4 (satellite nodule) N0-2M0 were identified. Patients with pure bronchoalveolar carcinoma were excluded. The primary endpoint studied was overall survival. Multiple covariates were analyzed for association with survival and recurrence. A total of 51 T4 N0-2 patients (men 22, women 29; median age 71 years [48 to 87]) underwent resection over a 7-year period. At a median follow-up of 26.4 months the estimated 5-year overall survival was 26% (95% confidence interval [CI] 14% to 50%; median survival 25.2 months). The estimated 5-year overall survival for T4 N0 patients was 40% (95% CI 23% to 68%; median survival 34.8 months). Size of the primary tumor, histology, and nodal status were significantly associated with overall survival; size and nodal status were significantly associated with disease-free survival. Our results indicate that T4 (satellite nodule) N0 patients experienced excellent survival after surgical resection. These data support surgical resection in node negative patients. Size, histology, and nodal status were important prognostic variables associated with outcome. Consideration should be given to multimodality treatment in patients with adverse prognostic features. Further larger multiinstitutional studies are required to validate these findings.

    Purpose: To compare the outcome of surgical resection followed by whole brain radiotherapy (WBRT) with WBRT alone in patients treated for single brain metastasis. Methods and Materials: The data from 195 patients with single brain metastases were retrospectively evaluated. Of the 195 patients, 99 underwent resection of the metastasis followed by WBRT and 96 underwent WBRT alone. Seven additional potential prognostic factors were investigated: age, gender, Eastern Cooperative Oncology Group performance score, tumor type, interval between initial tumor diagnosis and WBRT, extracranial metastases, and recursive partitioning analysis class. Both treatment groups were well balanced for these factors. Results: On multivariate analysis, improved survival was associated with resection (relative risk [RR], 1.20; 95% confidence interval [CI], 1.11-1.31; p < 0.001), lower recursive partitioning analysis class (RR, 1.58; 95% CI, 1.22-2.06; p < 0.001), age ≤61 years (RR, 1.79; 95% CI, 1.23-2.61; p = 0.002), Eastern Cooperative Oncology Group performance score of 0-1 (RR, 2.47; 95% CI, 1.70-3.59; p < 0.001), and the absence of extracranial metastases (RR, 1.99; 95% CI, 1.41-2.79; p < 0.001). Improved local control was associated with resection (RR, 1.25; 95% CI, 1.11-1.41; p < 0.001) and age ≤61 years (RR, 1.77; 95% CI, 1.09-2.88; p = 0.020). Improved brain control distant from the original site was associated with lower recursive partitioning analysis class (RR, 1.65; 95% CI, 1.03-2.69; p < 0.035), age ≤61 years (RR, 1.81; 95% CI, 1.12-2.96; p = 0.016), and the absence of extracranial metastases (RR, 2.42; 95% CI, 1.52-3.88; p < 0.001). Improved control within the entire brain was associated with surgery (RR, 1.24; 95% CI, 1.12-1.38; p < 0.001) and age ≤61 years (RR, 1.83; 95% CI, 1.21-2.77; p = 0.004). Conclusion: In patients with a single brain metastasis, the addition of resection to WBRT improved survival, local control at the original metastatic site, and control

    The neutrophil-to-lymphocyte ratio (neutrophil count divided by lymphocyte count) is a marker of inflammation associated with poor cancer outcomes. The role of neutrophil-to-lymphocyte ratio in borderline resectable pancreatic ductal adenocarcinoma is unknown. We hypothesized that increased neutrophil-to-lymphocyte ratio in patients with borderline resectable pancreatic ductal adenocarcinoma after neoadjuvant therapy is inversely associated with survival. We used our borderline resectable pancreatic ductal adenocarcinoma database to identify patients who had completed neoadjuvant therapy and underwent resection. The neutrophil-to-lymphocyte ratio difference was calculated as the neutrophil-to-lymphocyte ratio after neoadjuvant therapy minus the neutrophil-to-lymphocyte ratio before neoadjuvant therapy. Patients were assigned to the increased neutrophil-to-lymphocyte ratio cohort if the difference was ≥2.5 units; all others were assigned to the stable neutrophil-to-lymphocyte ratio cohort. Statistical analyses were performed with t test and regression. Of 62 patients identified, 43 were assigned to the stable neutrophil-to-lymphocyte ratio cohort, and 19 to the increased neutrophil-to-lymphocyte ratio cohort. There were no differences in stage, age, or sex. The preneoadjuvant neutrophil-to-lymphocyte ratio was 3.1 ± 2.4, whereas the postneoadjuvant neutrophil-to-lymphocyte ratio was 4.4 ± 3.5 (P = .002). Overall survival was worse in the increased neutrophil-to-lymphocyte ratio cohort compared with the stable neutrophil-to-lymphocyte ratio cohort (P = .009) with a Cox hazard ratio of 2.9 (P = .02). N0 disease conferred a survival advantage over N1 disease (Cox hazard ratio = 0.3, P = .01). On multivariate Cox hazard regression analysis, both increased neutrophil-to-lymphocyte ratio and N1 stage were associated with worse survival (P ratio in patients with borderline resectable pancreatic ductal adenocarcinoma. These findings support exploring

    Around 10 % of colorectal cancers are locally advanced at diagnosis. There are higher incidences for sigmoid and rectal cancer adhered to urinary bladder (UB) rather than other segments of colon cancer. Surgeons often performed partial cystectomy as possible for preservation of patient's life quality. This study investigates prognostic factors in patients who underwent bladder preservation en bloc resection for UB adherent colorectal cancer. From 2000 to 2011, 123 patients with clinically UB involvement colorectal cancer underwent primary colorectal cancer with urinary bladder resection. Seventeen patients were excluded because of the concurrent distant metastasis at diagnosis and another 22 patients were excluded because of total cystectomy with uretero-ileal urinary diversion. Finally, 84 patients with clinical stage IIIC (T4bN0M0, according to AJCC 7th edition) that underwent en bloc colorectal cancer resection with partial cystectomy were enrolled into this study for further analysis. Preoperative colovesical fistula and positive CT result were significantly more in the urinary bladder invasion group (p = 0.043 and 0.010, respectively). Pathological UB invasion is an independent predictor of intravesical recurrence (p = 0.04; HR, 10.71; 95 % CI = 1.12∼102.94) and distant metastasis (p = 0.016; HR, 4.85; 95 % CI = 1.34 ∼ 17.53) in multivariate analysis. For bladder preservation en bloc resection of urinary bladder adherent colorectal cancer, the pathological urinary bladder invasion is significantly associated with more urinary bladder recurrence and distant metastasis. This result helps surgeons make decisions at surgical planning and establish follow-up protocol.

    Results of Muller's muscle resection in patients with ptosis and its relationship with levator and Muller's muscle function. Prospective review of medical records of all pateints who underwent open sky Mullerectomy for correction of upper eyelid ptosis. The study period was from January 2008 to July 2009. Levator function, MRD1, Phenylepherine test result and extent of ptosis correction were recorded. Excised muscle tissue in few cases were subjected to histopathology. In 11 patients who underwent 13 mullerectomy procedures for correction of upper eyelid ptosis, MRD1 increased an average by 2.54 mm. The amount of ptosis correction was 4.28 mm in pateints with either good levator function and/or Muller's action and 1mm in patients where both responses to phenylepherine and levator functions were poor. Histopathology revealed both straited and smooth muscle tissue in the excised specimens in all cases. Mullerectomy porbably involves plication of the posterior layer of the levator aponeurosis. Results of Muller's muscle resection is good in patients with good levator function and/or good Mullers action and poor if both Muller and levator function are poor.

To report the results of lateral rectus muscle recession, medial rectus muscle resection, and superior oblique muscle transposition in the restoration and maintenance of ocular alignment in primary position for patients with total third-nerve palsy. Methods. The medical records of patients who underwent surgery between March 2007 and September 2011 for total third-nerve palsy were reviewed. All patients underwent a preoperative assessment, including a detailed ophthalmologic examination. Results. A total of 6 patients (age range, 14–45 years were included. The median preoperative horizontal deviation was 67.5 Prism Diopter (PD (interquartile range [IQR] 57.5–70 and vertical deviation was 13.5 PD (IQR 10–20. The median postoperative horizontal residual exodeviation was 8.0 PD (IQR 1–16, and the vertical deviation was 0 PD (IQR 0–4. The median correction of hypotropia following superior oblique transposition was 13.5 ± 2.9 PD (range, 10–16. All cases were vertically aligned within 5 PD. Four of the six cases were aligned within 10 PD of the horizontal deviation. Adduction and head posture were improved in all patients. All patients gained new area of binocular single vision in the primary position after the operation. Conclusion. Lateral rectus recession, medial rectus resection, and superior oblique transposition may be used to achieve satisfactory cosmetic and functional results in total third-nerve palsy.

    The extended transnasal approach, a recent surgical advancements for the ventral skull base, allows excellent midline access to and visibility of the anterior cranial fossa, which was previously thought to be approachable only via a transcranial route. The extended transnasal approach allows early decompression of the optic canals, obviates the need for brain retraction, and reduces neurovascular manipulation. Between 2004 and 2007, 11 consecutive patients underwent transnasal resection of anterior cranial fossa meningiomas--4 olfactory groove (OGM) and 7 tuberculum sellae (TSM) meningiomas. Age at surgery, sex, symptoms, and imaging studies were reviewed. Tumor size and tumor extension were estimated, and the anteroposterior, vertical, and horizontal diameters were measred on MR images. Medical records, surgical complications, and outcomes of the patients were collected. A gross-total removal of the lesion was achieved in 10 patients (91%), and in 1 patient with a TSM only a near-total (> 90%) resection was possible. Four patients with preoperative visual function defect had a complete recovery, whereas 3 patients experienced a transient worsening of vision, fully recovered within few days. In 3 patients (2 with TSMs and 1 with an OGM), a postoperative CSF leak occurred, requiring a endoscopic surgery for skull base defect repair. Another patient (a case involving a TSM) developed transient diabetes insipidus. The operative time ranged from 6 to 10 hours in the OGM group and from 4.5 to 9 hours in the TSM group. The mean duration of the hospital stay was 13.5 and 10 days in the OGM and TSM groups, respectively. Six patients (3 with OGMs and 3 with TSMs) required a blood transfusion. Surgery-related death occurred in 1 patient with TSM, in whom the tumor was successfully removed. The technique offers a minimally invasive route to the midline anterior skull base, allowing the surgeon to avoid using brain retraction and reducing manipulation of the large vessels and

    To assess laparoscopic radical resection of lower rectal cancer with telescopic anastomosis through transanal resection without abdominal incisions. From March 2010 to June 2014, 30 patients (14 men and 16 women, aged 36-78 years, mean age 59.8 years) underwent laparoscopic radical resection of lower rectal cancer with telescopic anastomosis through anus-preserving transanal resection. The tumors were 5-7 cm away from the anal margin in 24 cases, and 4 cm in six cases. In preoperative assessment, there were 21 cases of T1N0M0 and nine of T2N0M0. Through the middle approach, the sigmoid mesentery was freed at the root with an ultrasonic scalpel and the roots of the inferior mesenteric artery and vein were dissected, clamped and cut. Following the total mesorectal excision principle, the rectum was separated until the anorectal ring reached 3-5 cm from the distal end of the tumor. For perineal surgery, a ring incision was made 2 cm above the dentate line, and sharp dissection was performed submucosally towards the superior direction, until the plane of the levator ani muscle, to transect the rectum. The rectum and distal sigmoid colon were removed together from the anus, followed by a telescopic anastomosis between the full thickness of the proximal colon and the mucosa and submucosal tissue of the rectum. For the present cohort of 30 cases, the mean operative time was 178 min, with an average of 13 positive lymph nodes detected. One case of postoperative anastomotic leak was observed, requiring temporary colostomy, which was closed and recovered 3 mo later. The postoperative pathology showed T1-T2N0M0 in 19 cases and T2N1M0 in 11 cases. Twelve months after surgery, 94.4% patients achieved anal function Kirwan grade 1, indicating that their anal function returned to normal. The patients were followed up for 1-36 mo, with an average of 23 mo. There was no local recurrence, and 17 patients survived for > 3 years (with a survival rate of 100%). Laparoscopic radical

    The impact of hepatitis B virus (HBV) infection on outcomes after resection of intrahepatic cholangiocarcinoma (ICC) has not been reported. The aim of this study was to examine the impact of antiviral therapy on survival outcomes after liver resection for patients with ICC and underlying HBV infection. Data on 928 patients with ICC and HBV infection who underwent liver resection at two medical centers between 2006 and 2011 were analyzed. Data on viral reactivation, tumor recurrence, cancer-specific survival (CSS) and overall survival (OS) were obtained. Survival rates were analyzed using the time-dependent Cox regression model adjusted for potential covariates. Postoperative viral reactivation occurred in 3.3%, 8.3% and 15.7% of patients who received preoperative antiviral therapy, who did not receive preoperative antiviral therapy with a low, or a high HBV-DNA level (antiviral therapy (70.5%, 46.9% and 43.0%) compared with patients who did not receive antiviral therapy and had a high viral level (86.5%, 20.9% and 20.5%, all p antiviral therapy patients with a low viral level (71.7%, 35.5% and 33.5%, p = 0.057, 0.051 and 0.060, respectively). Compared to patients with a high viral level who received no antiviral therapy, patients who initiated antiviral therapy either before or after surgery had better long-term outcomes (HR 0.44 and 0.54 for recurrence; 0.38 and 0.57 for CSS; 0.46 and 0.54 for OS, respectively). Viral reactivation was associated with worse prognoses after liver resection for HBV-infected patients with ICC. Antiviral therapy decreased viral reactivation and prolonged long-term survival for patients with ICC and a high viral level. Postoperative hepatitis B virus reactivation was associated with an increased complication rate and a decreased survival rate after liver resection in patients with ICC and hepatitis B virus infection. Antiviral therapy before liver resection reduced the risk of postoperative viral reactivation. Both pre- and

    BACKGROUND: A variety of approaches are available for division of major vascular structures during laparoscopic colorectal resection. Ultrasonic coagulating shears (UCS), vascular staplers, plastic or titanium clips and electrothermal bipolar vessel sealing (EBVS) are currently available. We report our experience with an EBVS device, LigaSure (Covidien AG), used in division of the ileocolic, middle colic and inferior mesenteric arteries during laparoscopic colorectal resection. METHODS: We report the immediate outcome of 802 consecutive unselected patients who underwent elective laparoscopic colorectal cancer resection performed with use of the LigaSure (5 and 10 mm) at our institution over a 5-year period. Operative procedures included right hemicolectomy (n = 180), left hemicolectomy (n = 96), sigmoid colectomy (n = 347) and anterior resection (n = 179). Data were collected from a prospectively maintained cancer database and operative records. The procedures were performed primarily by three consultant surgeons with an interest in laparoscopic colorectal resection. RESULTS: Of 802 cases in which the LigaSure device was employed to divide major vascular structures, immediate effective vessel sealing was achieved in 99.8% (n = 800). Two patients experienced related adverse events both following division of the inferior mesenteric artery with a 5 mm LigaSure. Both patients had immediate uncontrolled haemorrhage that required laparotomy. CONCLUSIONS: Use of the LigaSure device to seal and divide the major mesenteric vessels during laparoscopic colorectal resection is very effective, with a high success rate of 99.8%. Caution should be exercised in elderly atherosclerotic patients, particularly when using the 5-mm LigaSure device.

    Initial management of diverticulitis with abscess formation has progressed from a surgical emergency to nonoperative management with antibiotics and percutaneous drainage followed by delayed resection. Controversy has arisen regarding the necessity of elective surgery, when nonoperative management has successfully resolved the index attack. The aim of this systematic review was to analyze the literature to determine the recurrence rate in those patients who were successfully managed nonoperatively and determine the role of elective surgical resection. An electronic literature search of PubMed, MEDLINE, EMBASE, and the Cochrane Database of Collected Reviews performed from 1986 to 2014. The search terms used were as follows: "diverticulitis," "abscess," "diverticular abscess," "percutaneous drainage," and "surgery." Studies included for review evaluated the management of diverticular abscesses and the subsequent role of delayed elective resection. All of the studies were systematically reviewed and underwent a meta-analysis. End points were the need for surgery and recurrent attacks without surgery. Twenty-two studies reporting a total of 1051 patients with acute diverticulitis with abscess formation (modified Hinchey grades IB and II) were included in the review. Percutaneous drainage was successful in 49% patients (diameter, >3 cm) and antibiotic therapy in 14% patients. Urgent surgery during the index hospitalization was performed in 30% of patients, elective resection in 36%, and no surgery in 35%. Recurrence rates were high, with 39% in patients awaiting elective resection and 18% in the nonsurgery group, with an overall recurrence rate of 28%. Of the whole cohort, only 28% had no surgery and no recurrence during follow-up. Sample size, heterogeneity, selection and treatment bias, and limited follow-up of included studies were limitations to this study. The evidence from the literature is weak but still suggests that complicated diverticulitis with abscess

    The survival benefit of neoadjuvant therapy for patients with borderline resectable pancreatic carcinoma has been reported recently. However, prognostic factors for this strategy have not been clearly elucidated. The aim of this study was to clarify prognostic factors for patients with borderline resectable pancreatic carcinoma who received neoadjuvant chemotherapy. Medical records of 66 patients with pancreatic carcinoma with arterial contact who intended to undergo tumor resection following neoadjuvant chemotherapy were analyzed retrospectively. Prognostic factors were investigated by analyzing the clinicopathological factors with univariate and multivariate survival analyses. Gemcitabine plus S-1 was generally used as neoadjuvant chemotherapy. The objective response rate was 24%, and normalization of serum tumor markers following neoadjuvant chemotherapy was achieved in 29 patients (44%). Of the 66 patients, 60 patients underwent tumor resection and the remaining six patients did not due to distant metastases following neoadjuvant chemotherapy. For all 66 patients, overall 1-, 2-, and 5-year survival rates were 87.8, 54.5, and 20.5%, respectively (median survival time, 27.1 months) and multivariate analysis revealed that normalization of serum tumor markers was found to be an independent prognostic factor of better overall survival (P = 0.023). Moreover, for 60 patients who undergo tumor resection, normalization of serum tumor markers (P = 0.005) was independently associated with better overall survival by multivariate analysis. Patients with pancreatic carcinoma with arterial contact who undergo neoadjuvant chemotherapy and experience normalization of serum tumor markers thereafter may be good candidates for tumor resection.

    Full Text Available Introduction: Tracheal stenosis is a complex condition caused by altered inflammatory response to injury and subsequent excessive circumferential scar formation. Surgical resection, wherever possible, offers the best long-term results. Nonsurgical methods provide immediate relief to all can be curative in few but mostly serve as an excellent bridge to surgery in majority. The purpose of this study is to retrospectively evaluate the outcome following surgery for benign tracheal stenosis at our center. Materials and Methods: This retrospective analysis was conducted on 18 patients who underwent resection and anastomosis for tracheal stenosis at our center between March 2012 and December 2015. Their records were analyzed for demography, history, clinical presentation, computed tomography, bronchoscopy details, preoperative interventions, indications for and details of surgery, the procedure performed, postoperative complications, and course during 6 months follow-up. Results: The patients had a varied list of pathologies for which they were either intubated or tracheostomized. The length of stenosis ranged between 1 cm and 4 cm. The diameter of stenotic segment ranged between 0 mm and 10 mm. Average length of resected segment was 3 cm, and number of tracheal rings resected ranged from 2 to 9. Postoperative complications occurred in four patients (22.22%. All our patients were in the “excellent outcome” category at discharge as well as at 3 months follow-up. Conclusions: Surgical management of tracheal stenosis is challenging and requires multidisciplinary team approach. Thorough preoperative preparation and multidisciplinary planning regarding need for and timing of surgery, meticulous intraoperative technique, and aggressive postoperative care is key to successful surgery, which can provide long-lasting cure to these patients.

    Abstract The occurrence of anastomotic leakage (AL) remains a major concern in the early postoperative stage. Because of the relatively high morbidity and mortality of AL in patients with laparoscopic low rectal cancer who receive an anterior resection, a fecal diverting method is usually introduced. The Valtrac™-secured intracolonic bypass (VIB) was used in open rectal resection, and played a role of protecting the anastomotic site. This study was designed to assess the efficacy and safety of the VIB in protecting laparoscopic low rectal anastomosis and to compare the efficacy and complications of VIB with those of loop ileostomy (LI). Medical records of the 43 patients with rectal cancer who underwent elective laparoscopic low anterior resection and received VIB procedure or LI between May 2011 and May 2013 were retrospectively analyzed, including the patients’ demographics, clinical features, and operative data. Twenty-four patients received a VIB and 19 patients a LI procedure. Most of the demographics and clinical features of the groups, including Dukes stages, were similar. However, the median distance of the tumor edge from the anus verge in the VIB group was significantly longer (7.5 cm; inter-quartile range [IQR] 7.0–9.5 cm) than that of the L1 group (6.0 cm; IQR 6.0–7.0 cm). None of the patients developed clinical AL. The comparisons between the LI and the VIB groups were adjusted for the significant differences in the tumor level of the groups. After adjustment, the LI group experienced longer overall postoperative hospital stay (14.0 days, IQR: 12.0, 16.0 days; P resection, appears to be a safe and effective, but time-limited, diverting technique to protect an elective low colorectal anastomosis.

    Summary Purpose Intracranial electroencephalography (EEG) is performed as part of an epilepsy surgery evaluation when noninvasive tests are incongruent or the putative seizure-onset zone is near eloquent cortex. Determining the seizure-onset zone using intracranial EEG has been conventionally based on identification of specific ictal patterns with visual inspection. High-frequency oscillations (HFOs, >80 Hz) have been recognized recently as highly correlated with the epileptogenic zone. However, HFOs can be difficult to detect because of their low amplitude. Therefore, the prevalence of ictal HFOs and their role in localization of epileptogenic zone on intracranial EEG are unknown. Methods We identified 48 patients who underwent surgical treatment after the surgical evaluation with intracranial EEG, and 44 patients met criteria for this retrospective study. Results were not used in surgical decision making. Intracranial EEG recordings were collected with a sampling rate of 2,000 Hz. Recordings were first inspected visually to determine ictal onset and then analyzed further with time-frequency analysis. Forty-one (93%) of 44 patients had ictal HFOs determined with time-frequency analysis of intracranial EEG. Key Findings Twenty-two (54%) of the 41 patients with ictal HFOs had complete resection of HFO regions, regardless of frequency bands. Complete resection of HFOs (n = 22) resulted in a seizure-free outcome in 18 (82%) of 22 patients, significantly higher than the seizure-free outcome with incomplete HFO resection (4/19, 21%). Significance Our study shows that ictal HFOs are commonly found with intracranial EEG in our population largely of children with cortical dysplasia, and have localizing value. The use of ictal HFOs may add more promising information compared to interictal HFOs because of the evidence of ictal propagation and followed by clinical aspect of seizures. Complete resection of HFOs is a favorable prognostic indicator for surgical outcome. PMID

    Children with spastic diplegia frequently show excessive knee extension (stiff-knee gait) throughout swing phase, which may interfere with foot clearance. Abnormal rectus femoris activity is commonly associated with a stiff-knee gait. Rectus femoris transfer has been recommended to enhance knee flexion during swing. However, recent studies suggest the transfer does not generate a knee flexor moment but diminishes knee extension moment in swing and MRI studies show the transferred tendons can be constrained by scarring to underlying muscles. Thus, it is possible knee flexion would be improved by distal rectus release rather than transfer since it would not be adherent to the underlying muscles. We therefore determined whether rectus femoris distal tendon resection improves knee ROM and kinematic characteristics of stiff-knee gait in patients with spastic diplegia. We studied 45 patients who underwent rectus femoris distal tendon resection as a part of multilevel surgery. Rectus femoris procedures were indicated based on kinematic characteristics of stiff-knee gait. All patients were walkers and had a mean age at surgery of 13 years (range, 6-22 years). We obtained gait analyses before surgery and at mean 2-year followup. We based postoperative assessment on clinical evaluation and gait analysis data. At followup, rectus femoris distal tendon resection was associated with improved knee ROM and timing of peak knee flexion in swing, and the absolute values of peak knee flexion became normal for those patients who showed abnormal preoperative values. Kinematic parameters of stiff-knee gait improved after rectus femoris distal tendon resection. Given the preliminary nature of our report, we intend to study the same patients to assess outcomes at a longer followup. Level IV, therapeutic study.

    The prognostic significance of the number of lymph nodes sampled (NLNS) during resection for non-small cell lung cancer (NSCLC) is unclear. The NLNS is influenced by many factors, and some have argued that it should be a surrogate for quality. We sought to determine the influence of the NLNS on overall survival and cancer-specific survival for surgically resected NSCLC. The California Cancer Registry was queried from 2004 to 2011 for cases of stage I to III NSCLC treated with surgical resection, identifying 16,393 patients. Kaplan-Meier and Cox proportional hazards modeling were used to determine the influence of NLNS on overall survival and cancer-specific survival. In all, 15,195 patients had information regarding nodal sampling. Eighty percent (13,167 of 15,195) were treated with lobectomy. Patients who were younger, male, non-Hispanic white, highest socioeconomic status, higher stage, or larger size tumor had more nodes removed. Sampling fewer than 10 nodes was associated with poorer overall survival when compared with sampling 10 or more nodes after adjustment for demographic and clinical factors for stage I: overall survival hazard ratio 1.78 (95% confidence interval: 1.54 to 2.05, p < 0.0001), hazard ratio 1.43 (95% confidence interval: 1.27 to 1.59, p < 0.0001), and hazard ratio 1.16 (95% confidence interval: 1.05 to 1.28, p = 0.004), for 0, 1 to 3, and 4 to 10 nodes, respectively. Of patients who underwent sublobar resection, 43.8% had no nodes sampled. For NSCLC, the NLNS influenced both overall survival and cancer-specific survival, but the influence is dependent on stage. Surgeons should perform mediastinal lymphadenectomy to maximize patient survival, but the optimal NLNS remains unclear. Copyright © 2017 The Society of Thoracic Surgeons. Published by Elsevier Inc.

    We sought to evaluate the clinical utility of chest tube management after pulmonary resection based on objective digital monitoring of pleural pressure and digital surveillance for air leaks. We prospectively recorded the perioperative data of 308 patients who underwent pulmonary resection between December 2013 and January 2016. We used information from a digital monitoring thoracic drainage system to measure peak air leakage during the first 24 hours after the operation, patterns of air leakage over the first 72 hours, and patterns of pleural pressure changes until the chest tubes were removed. There were 240 patients with lung cancer and 68 patients with other diseases. The operations included 49 wedge resections, 58 segmentectomies, and 201 lobectomies. A postoperative air leak was observed in 61 patients (20%). A prolonged air leak exceeding 20 mL/min lasting 5 days or more was observed in 18 patients (5.8%). Multivariate analysis of various perioperative factors showed forced expiratory volume in 1 second below 70%, patterns of air leakage, defined as exacerbating and remitting or without a trend toward improvement, and peak air leakage of 100 mL/min or more were significant positive predictors of prolonged air leak. Fluctuations in pleural pressure occurred just after the air leakage rate decreased to less than 20 mL/min. Digital monitoring of peak air leakage and patterns of air leakage were useful for predicting prolonged air leak after pulmonary resection. Information on the disappearance of air leak could be derived from the change in the rate of air leakage and from the increase in fluctuation of pleural pressure.

    Full Text Available Background: Low anterior rectal resection is an option for low rectal cancer. The aim of this study was to assess the clinical and manometric findings before and after low anterior resection in patients with rectal cancer. Methods: In a before-after prospective experimental study, 29 patients with colon cancer who were candidate for elective low anterior resection surgery in Imam Khomeini hospital were enrolled. In preoperative period, the data regarding the anorectal function were gathered and all the patients were assessed by an eight channel rectal manometer. After the surgery, patients were evaluated regarding current anorectal function and underwent rectal manometry for the second time. Results: The mean of defecation time was significantly higher in postoperative period compared with preoperative period (2.48±0.78 vs. 0.94±0.36 time per day. In postoperative period, gas incontinence was significantly higher in comparison to the preoperative period (27.59% vs. 0%. However, the fecal incontinence rates were comparable. Compared with preoperative period, max resting pressure was significantly reduced in postoperative period (53.20±17.45 vs. 64.32±17.33 mmHg. The same was true about max squeezing pressure (140.21±35.50 vs. 150.37±33.16 mmHg. Urgency also increased in postoperative period (48.28% vs. 0%. Conclusions: The results of this study revealed that following low anterior resection surgery for patients with rectal cancer, the defecation time, gas incontinence and urgency increase but max resting and squeezing pressure decrease.

    Soft tissue sarcoma (STS) of the chest wall is uncommon, and our knowledge is limited to small, single institutional case series. Although some series have examined prognostic factors for survival with this rare set of neoplasms, our knowledge of the patterns of relapse is limited. We performed a retrospective review of a prospectively maintained database of consecutive patients treated for STS of the chest wall. Predictors of survival and recurrence were analyzed using Cox and competing-risk regression analyses. From 1989 to 2011, 192 patients underwent resection for STS of the chest wall. The most common histopathologic type was desmoid (33 [17%]), followed by undifferentiated pleomorphic sarcoma (32 [16%]), liposarcoma (22 [11%]), and myxofibrosarcoma (22 [11%]). The median follow-up was 50.9 months. The 5- and 10-year survival rates were 73% and 61%, respectively. Recurrences occurred in 45 patients (23%): 17 developed local recurrences, and 28 developed distant recurrences. Among the patients who developed recurrences, the median time to event was 11.6 months for local recurrences and 13.5 months for distant recurrences. The most common histologic type among recurrences was undifferentiated pleomorphic sarcoma (n = 12), and the most common site of distant recurrences was lung (n = 18). The primary treatment modality for both local and distant recurrences was surgical resection; median survival after recurrence was 19.4 months. Recurrences of STS are common after surgical resection. Although local or distant recurrences can occur soon after surgery, both can often be treated with resection, producing reasonable outcomes. Copyright © 2013 The Society of Thoracic Surgeons.
