    Three-column lumbar spinal resection osteotomies including pedicle subtraction osteotomy (PSO), vertebral column resection (VCR), and total en bloc spondylectomy (TES) can potentially lead to dorsal root ganglion (DRG) injury which may cause postoperative dysesthesia (POD). The purpose of retrospective study was to describe the uncommon complication of POD in lumbar spinal resection osteotomies. Between January 2009 and December 2013, 64 patients were treated with lumbar three-column spinal resection osteotomies (PSO, n = 31; VCR, n = 29; TES, n = 4) in investigator group. POD was defined as dysesthetic pain or burning dysesthesia at a proper DRG innervated region, whether spontaneous or evoked. Non-steroidal antiinflammatory drugs, central none-opioid analgesic agent, neuropathic pain drugs and/or intervertebral foramen block were selectively used to treat POD. There were 5 cases of POD (5/64, 7.8 %), which consisted of 1 patient in PSO (1/31, 3.2 %), 3 patients in PVCR (3/29, 10.3 %), and 1 patient in TES (1/4, 25 %). After the treatment by drugs administration plus DRG block, all patients presented pain relief with duration from 8 to 38 days. A gradual pain moving to distal end of a proper DRG innervated region was found as the beginning of end. Although POD is a unique and rare complication and maybe misdiagnosed as nerve root injury in lumbar spinal resection osteotomies, combination drug therapy and DRG block have an effective result of pain relief. The appearance of a gradual pain moving to distal end of a proper DRG innervated region during recovering may be used as a sign for the good prognosis.

    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...

    In past decades, the surgical techniques for treating laryngeal carcinoma have been vastly improved. For circumscribed tumors, voice-conserving resections are possible and for extensive neoplasms, radical laryngectomy, sometimes combined with chemoradiation, has been developed. Postoperative complications regarding swallowing function are not uncommon. Radiologic examinations, especially pharyngography and videofluoroscopy, are most often used to evaluate patients with complications after laryngeal surgery. An optimized videofluoroscopic technique for evaluation of complications is described. The radiologic appearance of early and late complications, such as fistulas, hematomas, aspiration, strictures, dysfunction of the pharyngoesophageal sphincter, tumor recurrence, and metachronous tumors is demonstrated.

    A total of forty patients with resected N2 stage non-small cell lung cancer treated with postoperative adjuvant radiation therapy between Jan. 1975 and Dec. 1990 at the Department of Radiation Oncology, Yonsei University College of Medicine, Yonsei Cancer Center were retrospectively analysed to evaluate whether postoperative radiation therapy improves survival. Patterns of failure and prognostic factors affecting survival were also analysed. The 5 year overall and disease free survival rate were 26.3%, 27.3% and median survival 23.5 months. The 5 year survival rates by T-stage were T1 66.7%, T2 25.6% and T3 12.5%. Loco-regional failure rate was 14.3% and distant metastasis rate was 42.9% and both 2.9%. Statistically significant factor affecting distant failure rate was number of positive lymph nodes(>= 4). This retrospective study suggests that postoperative radiation therapy in resected N2 stage non-small cell lung cancer can reduce loco-regional recurrence and may improve survival rate as compared with other studies which were treated by surgery alone. Further study of systemic control is also needed due to high rate of distant metastasis

    Background: The 5-year survival of patients with completely resected node-positive gastric cancer ranges from 15% to 25%. We explored the feasibility of a chemoradiation regime consisting of concomitant hyperfractionated radiotherapy and 5-fluorouracil protracted venous infusion (5-FU PVI). Materials and Methods: Forty patients received a total or partial gastrectomy operation and D2 nodal resection for Stage III gastric cancer; they were then irradiated by linac with 6-15-MV photons. The target included the gastric bed, the anastomosis, stumps, and regional nodes. A total dose of 55 Gy was given in 50 fractions using 1.1 Gy b.i.d. All patients received a concomitant 200 mg/m2/day 5-FU PVI. Patients were examined during the follow-up period as programmed. Toxicity was recorded according to RTOG criteria. Results: After a median follow-up of 75.6 months (range: 22-136 months), 24 (60%) patients had died, and 16 (40%) were alive and free of disease. The 5-year actuarial incidence of relapse was 39%, 22%, and 2% for distant metastases, out-field peritoneal seeding, and in-field local regional recurrences, respectively. The 5-year actuarial cause-specific survival was 43%. Three patients survived more than 11 years. Acute ≥ Grade 3 toxicity consisted of hematologic (22.5%) and gastrointestinal toxicity (nausea and vomiting 22.5%, diarrhea 2.8%, and abdominal pain 2.6%). No late toxicity was observed. Conclusion: This regime of concomitant 5-FU PVI and hyperfractionated radiotherapy was well tolerated and resulted in successful locoregional control and satisfactory survival

    The purpose of this study was to determine whether advancement of the levator aponeurosis in external levator resection surgery or Mueller's muscle and conjunctiva in Mueller's muscle conjunctival resection (MMCR) surgery has a differential effect on variation in eyelid position during the postoperative period. In this retrospective observational cohort study, 2 groups of patients were defined. The first underwent MMCR surgery without tarsectomy by surgeon 1. The second underwent external levator resection without dissection posterior to the levator aponeurosis by surgeon 2. Marginal reflex distance (MRD1) was calculated based on digital photographs at baseline, 1 week postoperatively and at 3-month follow up. The primary outcome measure was change in MRD1 over time. The secondary outcome was defined as the proportion of patients with minimal early postoperative change (change of MRD1 less than 0.5 mm at 1 week postoperatively). Repeated measures analysis of variance, t test, and chi-square analyses were performed. Of the 114 eyes in the sample, there were 68 in the MMCR group and 46 in the external levator resection group. A significant interaction between group and time was noted (p MRD1 over time was different between the groups. Bonferroni corrected multiple comparisons yielded significant differences between each time point for MMCR surgery (p MRD1 was noted for the external levator resection group from the early to late postoperative visit. Comparing each time point across groups revealed significantly lower MRD1 for the MMCR group at the early postoperative visit (p MRD1 did not significantly differ between the groups. Regarding the secondary outcome, patients undergoing MMCR surgery were 3.7× as likely to demonstrate MRD1 at week 1 (p MRD1 increase >1 mm from the early postoperative to the late postoperative time points. Both external levator resection and MMCR can effectively elevate the eyelid in cases of primary involutional ptosis, and have similar

    Our purpose was to correlate the morphological changes seen on MRI studies of the sellar region after trans-sphenoidal resection of pituitary adenomas with clinical and hormonal studies. Between January 1993 and March 1994, 16 patients with a pituitary adenoma (9 macroadenomas and 7 microadenomas) were subjected to trans-sphenoidal resection and included in a prospective study. The protocol consisted of MRI, hormonal and visual studies at the following times: immediately postoperative (1st week), 1st month, 4th month and 1st year after surgery. The evolution of the contents of the sella turcica (tumour remnant, packing material and gland tissue), effects on the infundibulum, optic chiasm, cavernous sinus and sphenoid sinus were correlated with the clinical and hormonal studies. Stabilisation of the postsurgical changes occurred by the 4th month. Tumour remnants were noted in the immediate postoperative period in macroadenomas. Compression of the infundibulum was the only reliable indicator of possible involvement. Optic chiasm compression, defined as close contact between the chiasm and the tumour, was the only morphological finding that indicated visual impairment. There was no standard repneumatisation pattern in the sphenoid sinus, since mucosal changes resembling sinusitis were one of the postsurgical changes. We found MRI not to be useful for follow-up of microadenomas. (orig.). With 4 figs., 4 tabs

    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.

    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.

    Early postoperative small bowel obstruction is associated with considerable morbidity and mortality but has not been well documented in the era of laparoscopic surgery for colorectal cancer. Consecutive patients who had undergone laparoscopic resection for colorectal cancer were studied. In total, 1787 patients (105 with and 1682 without early postoperative small bowel obstruction) with colorectal cancer requiring laparoscopic colorectal surgery were evaluated in this study. Ten patients (0.56% among the total patient population, 9.5% among patients who experienced early postoperative small bowel obstruction) who did not respond to conservative treatment for more than 14 days required surgical intervention. Multivariate analysis showed that male sex (adjusted odds ratio [AOR]=2.27), combined operation (AOR=2.23), and diverting stoma (AOR=4.79) were associated with a higher early postoperative small bowel obstruction rate. For factors related to surgical difficulty, open conversion (AOR=2.85), blood transfusion (AOR=3.51), and an operation time longer than 180 minutes (AOR=1.91) were independent factors associated with an increased early postoperative small bowel obstruction rate. Early postoperative small bowel obstruction following laparoscopic resection for colorectal cancer occurred in 5.9% of patients. Factors for predicting the development of early postoperative small bowel obstruction in patients with colorectal cancer are variables reflective of a more difficult surgery, rather than pathologic disease severity or anatomical location. In addition, most patients with early postoperative small bowel obstruction improved with conservative treatment, and surgical treatment was rarely needed.

    The occurrence of remote epidural hematoma as a postoperative complication after intracranial tumor resection is rare. This study reviewed experiences treating these hematomas and speculated on the causes of this disease. This study reviewed the treatment experience of 14 such cases. The 14 patients included 10 males and 4 females, with an age range of 19 to 65 years old. Six cases of tumors occurred in the sellar region, two cases in the lateral ventricle, one case in the fourth ventricle, one case in a cerebellar hemisphere, and four cases in other sites. Among them, five cases were complicated with supratentorial hydrocephalus. The tumors included five cases of meningioma tumors, two cases of pituitary adenomas, three cases of ependymomas, two cases of craniopharyngiomas, one case of astrocytoma, and one case of tuberculosis tumor. For the cases complicated with hydrocephalus, ventricular drainage was provided if needed, and the tumor resection was then performed, with close observation for postoperative changes. If neurological symptoms and disturbance of consciousness occurred, computed tomography (CT) examination was immediately performed. If a remote epidural hematoma was found, the hematoma was evacuated by craniotomy. The patients were followed up after surgery. In the five cases complicated with hydrocephalus, ventricular drainage was first provided for three cases. All of the 14 cases underwent total tumor resection, and postoperative remote epidural hematoma occurred in all cases, including eight cases on the ipsilateral side and adjacent to the supratentorial operative field; two cases occurred on the contralateral side; two cases occurred on bilateral sides; and two cases occurred in distant areas (with infratentorial surgery, the hematoma occurred on the supratentorial area). Postoperative remote epidural hematoma usually occurred 0.5-5 h after the tumor resection, when the tentorial hernia had already occurred. Following tumor resection and

    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.

    2014-03-01

    Ingrown (or ingrowing) toenail is a commonly used term for onychocryptosis, in which the nail becomes inserted into the lateral fold of the toe. The resulting effect on a person's health, well-being, and ability to work suggests the importance of clear treatment guidance, but little consensus exists. To explore postoperative recovery after surgery for ingrown toenails using chemical (sodium hydroxide (NaOH)) or mechanical (wedge resection) matricectomy and thus contribute to understanding within the field on which to base treatment guidelines. One hundred sixty-one procedures were undertaken, 94 using NaOH and 67 using wedge resection. Four measures of postoperative recovery were recorded: recurrence, infection, time to discharge, and number of postoperative visits. Patients treated with NaOH had lower rates of recurrence (p = .048) and infection (p = .03) than those treated with wedge resection, and time to discharge was shorter (p = .02), but they had more postoperative visits (p = .003). Low rates of recurrence and infection and short postoperative recovery time were found after both procedures, with a small advantage with treatment with NaOH. The authors argue for the value of clinical intervention using matricectomy in early stages to avoid complications resulting from granulation tissue growth. © 2014 by the American Society for Dermatologic Surgery, Inc.

    Lung scintigraphy and ordinary lung function test as well as split lung function test by using bronchospirometry was performed in 78 patients with primary lung cancer and clinical significance of ventilation and perfusion scintigraphy was evaluated. Results obtained from this study are as follows. 1) The ratio of right VC to total VC obtained by preoperative bronchospirometry was well correlated to the ratio of right lung count to the total lung count obtained by ventiration and/or perfusion scintigraphy (r = 0.84, r = 0.69). 2) Evaluation of the data obtained from the patients undergoing pneumonectomy indicated that the right and left VC obtained preoperatively by bronchospirometry have their clinical significance only in the form of left to right ratio not in the form their absolure value. 3) As to the reliability of predicting the residual vital capacity after pneumonectomy on the basis of left-to-right of lung scintigraphy, ventilation scintigraphy is more reliable than perfusion scintigraphy. 4) Irrespective of using ventilation scintigraphy or perfusion scintigraphy, Ali's formular showed high reliability in predicting the residual vital capacity as well as FEV 1.0 after lobectomy. 5) Reduction of the perfusion rate in the operated side of the lung is more marked than of the ventilation rate, resulting in a significant elevation of ventilation/perfusion ratio of the operated side of the lung. From the results descrived above, it can be said that lung ventilation and perfusion scintigraphy are very useful method to predict the residual lung function as well as the change of ventilation/perfusion ratio after pulmonary resection.

    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.

    Optimal management of postoperative radiation therapy for completely resected invasive thymoma remains controversial. This study was conducted to assess the efficacy of postoperative mediastinal irradiation in patients with completely resected invasive thymoma. Between 1981 and 1996, 21 patients with completely resected invasive thymoma were referred for postoperative mediastinal irradiation. The distribution of Masaoka stages was stage II in 14 patients and stage III in seven patients. Nine patients had pleural invasion by the tumor. Thirteen patients were treated with a localized field and eight were treated with the whole mediastinal field with boost. The total dose to the primary tumor was 40-61 Gy (median: 52 Gy). The median follow-up time of the 16 living patients was 67 months (range: 29-202 months). The 5- and 10-year actuarial overall survival rates in all patients were both 77%. Relapses were observed in five patients, in all of whom the sites of the first relapse involved pleural dissemination. There were no relapses within the irradiated field in any of the 21 cases. Five of nine (56%) patients with pleural invasion had relapse of pleural dissemination, while 0 of 12 (0%) patients without pleural invasion had relapse. In univariate analysis, pleural invasion had a statistically significant impact on intrathoracic control (P=0.01). The results indicated that pleural invasion might be predictive of pleural-based relapse for completely resected invasive thymoma. In patients with pleural invasion, mediastinal irradiation alone might be insufficient to avoid pleural-based relapse even after complete resection. (author)

    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.

    Right ventricular (RV) dysfunction after pulmonary resection in the early postoperative period is documented by reduced RV ejection fraction and increased RV end-diastolic volume index. Supraventricular arrhythmia, particularly atrial fibrillation, is common after pulmonary resection. RV assessment can be done by non-invasive methods and/or invasive approaches such as right cardiac catheterization. Incorporation of a rapid response thermistor to pulmonary artery catheter permits continuous measurements of cardiac output, right ventricular ejection fraction, and right ventricular end-diastolic volume. It can also be used for right atrial and right ventricular pacing, and for measuring right-sided pressures, including pulmonary capillary wedge pressure. This study included 178 patients who underwent major pulmonary resections, 36 who underwent pneumonectomy assigned as group (I) and 142 who underwent lobectomy assigned as group (II). The study was conducted at the cardiothoracic surgery department of Benha University hospital in Egypt; patients enrolled were operated on from February 2012 to February 2016. A rapid response thermistor pulmonary artery catheter was inserted via the right internal jugular vein. Preoperatively the following was recorded: central venous pressure, mean pulmonary artery pressure, pulmonary capillary wedge pressure, cardiac output, right ventricular ejection fraction and volumes. The same parameters were collected in fixed time intervals after 3 hours, 6 hours, 12 hours, 24 hours, and 48 hours postoperatively. For group (I): There were no statistically significant changes between the preoperative and postoperative records in the central venous pressure and mean arterial pressure; there were no statistically significant changes in the preoperative and 12, 24, and 48 hour postoperative records for cardiac index; 3 and 6 hours postoperative showed significant changes. There were statistically significant changes between the preoperative and

    Institutionalized patients pose various surgical difficulties as many have conditions requiring psychiatric medications with the propensity for anticholinergic side effects. This study was initiated to determine the impact of institutionalization and anticholinergic medication on postoperative outcomes. A total of 430 colorectal resection cases from 2006 to 2012 were studied. Among them, 19 were institutionalized patients and 17 were on long-term anticholinergic medications. Surgical outcomes were quantified by Clavien scoring, need for reoperations and postoperative deaths. Patients who were institutionalized or on anticholinergic medication were more likely to have increased postoperative morbidity requiring invasive interventions or worse (Clavien score ≥ 3; odds ratios 5.02 and 3.63, 95% confidence intervals 1.93-13.06 and 1.29-10.21 respectively). However, only institutionalization was found to be an independent risk factor. This study identified institutionalized patients as a higher risk group associated with postoperative complications compared to patients from the community. Thus, they merit a more thorough preoperative optimization closer postoperative monitoring regime. Copyright © 2015. Published by Elsevier Taiwan.

    In malignant brain tumours which may disseminate staging, usually by cranial and spinal MRI is necessary. If MRI is performed in the postoperative period pitfalls should be considered. Nonspecific subdural contrast enhancement on spinal staging MRI is rarely reported after resection of posterior fossa tumours, which may be mistaken for dissemination of malignancy. We investigated the frequency of spinal subdural enhancement after posterior cranial fossa neurosurgery in children. We reviewed 53 postoperative spinal MRI studies performed for staging of paediatric malignant brain tumours, mainly infratentorial primitive neuroectodermal tumours 2-40 days after surgery. There was contrast enhancement in the spinal subdural space in seven cases. This was not seen in any of eight patients who had been operated upon for a supratentorial tumour. After resection of 45 posterior cranial fossa tumours the frequency of subdural enhancement was 15.5%. MRI showing subdural enhancement was obtained up to 25 days postoperatively. No patient with subdural enhancement had cerebrospinal fluid (CSF) examinations positive for tumour cells or developed dissemination of disease in the CSF. Because the characteristic appearances of subdural contrast enhancement, appropriate interpretation is possible; diagnosis of neoplastic meningitis should rarely be impeded. Because of the striking similarity to that in patients with a low CSF-pressure syndrome and in view of the fact that only resection of tumours of the posterior cranial fossa, usually associated with obstructive hydrocephalus, was followed by this type of enhancement one might suggest that rapid changes in CSF pressure are implicated, rather the effects of blood introduced into the spinal canal at surgery.

    Transurethral resection of prostate (TURP) is considered the gold standard for the surgical treatment of BPH. Irrigant fluid absorption by the patient is a potentially serious complication of TURP and can lead to dilutional hyponatremia and TURP syndrome. Other common complications of TURP include urinary tract infection and secondary haemorrhage. The objective of this study was to compare the frequency of postoperative complications (Urinary Tract infection and dilutional hyponatremia) between 1.5% glycine and sterile distilled water used as irrigant in BPH patients after TURP. Methods: This randomized controlled trial was conducted in department of Urology, PIMS Islamabad, from August 2013 to February 2014. A total of 170 adult male patients between 50-80 years of age undergoing TURP with prostate volume more than 30cc on ultrasound. 85 patients each were randomly allocated to two groups. In group-A, glycine was used as irrigant solution during TURP while in group-B distilled water was used. Serum sodium levels were measured at 6th postoperative hour to look for dilutional hyponatremia. On the 15th postoperative day they were inquired about any clinical features of urinary tract infection. Also urine routine examination was performed to look for the presence of WBCs in the urine. Results: Post-operative dilutional hyponatremia was observed in 13 (15.3%) patients in Group A and in 10 (11.8%) patients in group-B. The difference between both the groups being non-significant (p-value=0.501).Frequency of postoperative urinary tract infection on 15th postoperative day in group-A was 23(27.1%) while in group-B it was 16 (18.8%), the difference among both the groups being insignificant (p-value=0.202). Conclusion: Although the frequency of postoperative complications like UTI and dilutional hyponatremia was less with sterile distilled water, yet, the difference was statistically not significant.

    As surgical resection is not curative in Crohn's disease, postoperative recurrence remains a crucial issue. The selection of patients, according to available risk factors, remains disappointing in clinical practice highlighting the need for better criteria, such as histologic features. To investigate whether submucosal and myenteric plexitis increase the risk of endoscopic, clinical and surgical postoperative recurrence in Crohn's disease. From the pathology department database, we retrospectively retrieved the data of all the patients who have undergone ileocolonic resection for Crohn's disease. Two pathologists, blinded from clinical data, reviewed all specimens to evaluate the presence of plexitis at the proximal resection margin. Of the 75 included CD patients, 19 (25.3%) had histological involvement of resection margin. Inflammatory cells count for myenteric and submucosal plexus were performed in 56 patients. In multivariate analysis, the myenteric plexitis was a risk factor for endoscopic postoperative recurrence (HR 8.83 CI95% [1.6-48.6], p=0.012), and the presence of at least one myenteric lymphocyte (HR 4.02 CI95% [1.4-11.2], p=0.008) was predictive of clinical postoperative recurrence. We observed no histologic predictor for surgical postoperative recurrence. Myenteric plexitis in proximal margins of ileocolonic resection specimens is independently associated with endoscopic and clinical postoperative recurrence in Crohn's disease.

    The role of adjuvant radiotherapy (RT) for patients with stage III thymoma after complete resection is not definite. Some authors have advocated postoperative RT after complete tumor resection, but some others suggested observation. In this study, we retrospectively evaluated the effect of postoperative RT on survival as well as tumor control in patients with Masaoka stage III thymoma. Between June 1982 and December 2010, 65 patients who underwent complete resection of stage III thymoma entered the study. Fifty-three patients had adjuvant RT after surgery (S + R) and 12 had surgery only (S alone). Of patients who had adjuvant RT, 28 had three-dimensional conformal RT (3D-CRT)/intensity modulated RT (IMRT) and 25 had conventional RT. A median prescribed dose of 56 Gy (range, 28–60 Gy) was given. The median follow-up time was 50 months (range, 5–360 months). Five- and 10-year overall survival (OS) rates were 91.7% and 71.6%, respectively, for S + R and 81.5% and 65.2% for S alone (P = 0.5), respectively. In the subgroup analysis, patients with 3D-CRT/IMRT showed a trend of improved 5-year OS rate compared with conventional RT (100% vs. 86.9%, P =0.12). Compared with S alone, the 5-year OS rate was significantly improved (100% vs. 81.5%, P = 0.049). Relapses occurred in 15 patients (23.1%). There was a trend of lower crude local recurrence rates for S + R (3.8%) compared with S alone (16.7%) (P = 0.09), whereas the crude regional recurrence rates were similar (P = 0.9). No clear dose–response relationship was found according to prescribed doses. Adjuvant 3D-CRT/IMRT showed potential advantages in improving survival and reducing relapse in patients with stage III thymoma after complete resection, whereas adjuvant RT did not significantly improve survival or reduce recurrence for the cohort as a whole. Doses of ≤ 50 Gy may be effective and could be prescribed for adjuvant RT. To confirm the role of adjuvant 3D-CRT/IMRT in patients who undergo a complete

    To study surgical treatment of postoperative stricture of anastomosis for lower rectal cancer. The data of 9 cases who were diagnosed as postoperative stricture of anastomosis after operation of intersphincteric resection for lower rectal cancer during January 2008 to June 2011 were analyzed retrospectively. Transanal excision of stricture were used in 3 cases diagnosed as membranous stricture. Transanal radial incision of stricture were used in 5 cases diagnosed as tubulous stricture. Biologic patch was used to repair the defect of the posterior wall of rectum after excision of severe stricture in 1 case. All 9 cases of postoperative stricture of anastomosis were cured by surgery. Anal dilation were performed every day by patients themselves after discharge. Digital examination showed that 1 to 2 fingers could pass through the anastomosis after operation. The patient whose rectal defect was repaired by biological patch underwent colonoscopy examination two weeks after operation. Colonoscopy showed that the biological patch had been filled with granulation and integrated into the surrounding intestinal tissue. All patients defecated without difficulty and the anal function of all patients was good after restoration of intestinal continuity. Aggressive surgery, combining with the use of biological patch if necessary is an effective therapy of postoperative stricture of anastomosis for lower rectal cancer.

    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)

    This meta-analysis aimed to provide a pooled analysis of clinical studies correlating postoperative radiotherapy (PORT) with survival in patients with completely resected thymoma. According to the recommendations of the Cochrane Collaboration, we established a rigorous study protocol. An electronic search was conducted using online databases. Hazard ratios (HRs) and 95% confidence intervals (CIs) were used in this meta-analysis and were calculated from published survival data. A meta-analysis was conducted to assess the impact of PORT in completely resected thymoma on overall survival (OS), disease-free survival (DFS). and disease-specific survival (DSS). We also performed a subgroup analysis for OS of patients with stage II and stage III thymoma. Fourteen studies, which included 3,823 patients (2,096 patients who received PORT and 1,727 patients who did not receive PORT), met the selection criteria. From the available data, the thymoma patients with PORT who did not undergo resection did not have significantly improved OS (HR 0.99; 95% CI 0.87 to 1.13; p = 0.87), DFS (HR 1.21; 95% CI 0.97 to 1.51; p = 0.09), or DSS (HR 0.66; 95% CI 0.39 to 1.13; p = 0.13) compared with the patients who did not undergo PORT. However, our subgroup analysis showed a significant difference in OS in patients with stage II thymoma (HR 0.57; 95% CI 0.41 to 0.80; p = 0.001) and patients with stage III thymoma (HR 0.73; 95% CI 0.59 to 0.90; p = 0.004). Our results showed that for completely resected thymoma, PORT had no advantage in the overall group of patients but increased OS in the patients with stage II and III thymoma after a complete resection. On the basis of this study, PORT is beneficial in patients with stage II and III patients after a complete resection. Copyright © 2016 The Society of Thoracic Surgeons. Published by Elsevier Inc.

    Background Sarcopenia is a surrogate marker of patient frailty that estimates the physiologic reserve of an individual patient. We sought to investigate the impact of sarcopenia on short- and long-term outcomes in patients having undergone surgical intervention for primary hepatic malignancies. Methods Ninety-six patients who underwent hepatic resection or liver transplantation for HCC or ICC at the John Hopkins Hospital between 2000 and 2013 met inclusion criteria. Sarcopenia was assessed by the measurement of total psoas major volume (TPV) and total psoas area (TPA). The impact of sarcopenia on perioperative complications and survival was assessed. Results Mean age was 61.9 years and most patients were men (61.4 %). Mean adjusted TPV was lower in women (23.3 cm3/m) versus men (34.9 cm3/m) (Psarcopenia. The incidence of a postoperative complication was 40.4 % among patients with sarcopenia versus 18.4 % among patients who did not have sarcopenia (P=0.01). Of note, all Clavien grade ≥3 complications (n=11, 23.4 %) occurred in the sarcopenic group. On multivariable analysis, the presence of sarcopenia was an independent predictive factor of postoperative complications (OR=3.06). Sarcopenia was not associated with long-term survival (HR=1.23; P=0.51). Conclusions Sarcopenia, as assessed by TPV, was an independent factor predictive of postoperative complications following surgical intervention for primary hepatic malignancies. PMID:25389056

    To evaluate a closed-loop system providing continuous monitoring and strict control of perioperative blood glucose following pancreatic resection. Prospective, randomized clinical trial. Thirty patients who had pancreatic resection for pancreatic neoplasm. Patients were prospectively randomized. Perioperative blood glucose levels were continuously monitored using an artificial endocrine pancreas (STG-22). Glucose levels were controlled using either the sliding scale method (sliding scale group, n = 13) or the artificial pancreas (artificial pancreas group, n = 17). Incidence of severe hypoglycemia (artificial pancreas. The secondary outcome measure was the total amount of insulin required for glycemic control in the first 18 hours after pancreatic resection in each patient group. In the sliding scale group, postoperative blood glucose levels rose initially before reaching a plateau of approximately 200 mg/dL between 4 and 6 hours after pancreatectomy. The levels remained high for 18 hours postoperatively. In the artificial pancreas group, blood glucose levels reduced steadily, reaching the target zone (80-110 mg/dL) by 6 hours after surgery. The total insulin dose administered per patient during the first postoperative 18 hours was significantly higher in the artificial pancreas group (mean [SD], 107 [109] IU) than the sliding scale group (8 [6] IU; P artificial endocrine pancreas to control pancreatogenic diabetes after pancreatic resection is an easy and effective way to maintain near-normal blood glucose levels. The artificial pancreas shows promise for use as insulin treatment for patients with pancreatogenic diabetes after pancreatic resection.

    Antibiotic prophylaxis has been recommended to reduce post-operative infectious complications. Discontinuation of post-operative antibiotic administration within 24 hours of operation is currently recommended. Many surgeons, however, conventionally tend to extend the duration of prophylactic antibiotic use. In this study, we performed a retrospective analysis to assess the efficacy of extended post-operative antibiotic use in patients who underwent elective liver resection. A total of 208 consecutive patients who underwent liver resection without biliary reconstruction were investigated. Patients were divided into two groups according to the duration of post-operative antibiotic use: Only once after the operation (the post-operative day [POD] 0 group) and until three days after the operation (the POD 3 group). Post-operative complications in the two groups were analyzed and compared. Incisional surgical site infections (SSIs) were observed in 5% of the POD 0 group and 3% of the POD 3 group (p = 0.517). Organ/space SSIs were observed in 2% of the POD 0 group and 3% of the POD 3 group (p = 0.694). Overall infectious complications including SSIs and remote site infections were observed in 12% of the POD 0 group and 11% of the POD 3 group. Multi-variable analyses revealed that the short-term post-operative antibiotic regimen did not confer additional risk for infectious complications. In elective liver resection, the administration of prophylactic antibiotics on the operative day alone appears to be sufficient, because no additional benefit in the incidence of post-operative infectious complications was conferred on patients given antibiotic agents for three days.

    Oncological margins and prognosis are the most important factors for operative planning of soft tissue sarcomas, but prediction of postoperative function is also necessary. The purpose of this study was to predict the knee flexion strength and postoperative function after knee flexor muscle resection for soft tissue sarcoma of the lower limbs. Seventeen patients underwent knee flexor muscle resection for soft tissue sarcoma of the lower limbs between 1991 and 2015. The type of resected muscles was surveyed, knee flexion strength (ratio of affected to unaffected side) was evaluated using the Biodex System isokinetic dynamometer, and differences between the type of resected muscles were examined. The Musculoskeletal Tumor Society (MSTS) score, Toronto Extremity Salvage Score (TESS), European Quality of Life-5 Dimensions (EQ-5D), and Short Form 8 (SF-8) were used to assess postoperative function and examine correlations with flexion strength. The cutoff value for flexion strength to predict good postoperative results was calculated by a receiver operating characteristic (ROC) curve and Fisher's exact test. Median flexion strength decreased in the resection of sartorius (97.8%), gracilis (95.4%), gastrocnemius (85.2%; interquartile range (IQR): 85.0-86.2), medial hamstrings (semimembranosus and semitendinosus, 76.2%; IQR: 73.3-78.0), lateral hamstrings (long and short head of biceps femoris, 66.1%; IQR: 65.9-70.4), and bilateral hamstrings (27.3%; IQR: 26.6-31.5). A significant difference was observed between lateral and bilateral hamstrings resection (P=0.049). Flexion strength was associated with lower functional scales (MSTS score, P=0.021; TESS, P=0.008; EQ-5D, P=0.034). Satisfactory function was obtained at a flexion strength cutoff value of 65.7%, and strength remained above the cutoff value up to unilateral hamstrings resection. Greater knee flexor muscles resection can result in functional deficits that are associated with decreased flexion strength. If

    Laparoscopic sigmoid resection is a feasible and frequent operation for patients who suffer from recurrent diverticulitis. There is still an ongoing debate about the optimal timing for surgery in patients who suffer from recurrent diverticulitis episodes. In elective situations the complication rate for this procedure is moderate, but there are patients at high risk for perioperative complications. The few identified risk factors so far refer to open surgery. Data for the elective laparoscopic approach is rare. The objective of this study was to identify potential predictive risk factors for intra- and postoperative complications in patients who underwent laparoscopic sigmoid resection due to diverticular disease. Uni- and multivariate analyses of a prospectively gathered database (1993-2006) were performed on a consecutive series of 526 patients who underwent laparoscopic sigmoid resection due to recurrent diverticulitis in a single institution. Patients were assessed for demographic data, operative indications, and intra- and postoperative complications. Altogether, we analyzed 17 potential risk factors to identify significant influence on the intra- and postoperative outcome, including timing of surgery. Statistical analysis of specific medical and surgical complications revealed anemia, previous myocardial infarction, heart failure, experience of the surgeon, and male gender, as independent predictive risk factors for postoperative complications. Patients older than age 75 years was the only independent risk factor for intraoperative complications in a multiple logistic regression model. Early elective surgery led to increased conversion rate but did not influence the postoperative complication rate. This large, single-center study provides first evidence of the significance of specific predictive risk factors for intra- and postoperative complications in laparoscopic sigmoid resection for diverticular disease.

    The metrics for measuring early postoperative morbidity after resection of pancreatic neoplastic tumors are overall morbidity, severe surgery-related morbidity, frequency of reoperation and reintervention, in-hospital, 30-day and 90-day mortality and length of hospital stay. Thirty-day readmission after discharge is additionally an indispensable criterion to assess quality of surgery. The metrics for surgery-associated long-term results after pancreatic resections are survival times, new onset of diabetes (DM), impaired glucose tolerance, exocrine pancreatic insufficiency, body mass index and GI motility dysfunctions. Following pancreaticoduodenectomy (PD) performed on pancreatic normo-glycemic patients for malignant and benign tumors, 4-30% develop postoperative new onset of diabetes. Long-term persistence of diabetes mellitus is observed after surgery for benign tumors in 14% and in 15.5% of patients after cancer resection. Pancreatic exocrine insufficiency after PD is observed in the early postoperative period in 23-80% of patients. Persistence of exocrine dysfunctions exists in 25% and 49% of patients. Following left-sided pancreatic resection, new onset DM is observed in 14% of cases; an exocrine insufficiency persisting in the long-term outcome is observed in 16-28% of patients.

    A randomized controlled trial was performed to assess the outcome of early oral postoperative feeding (EOF) compared with traditional oral feeding (TOF) in gynecologic oncology patients undergoing laparotomy with associated intestinal resection. Patients aged 18-75 years, undergoing elective laparotomy, and with preoperative diagnosis of gynecologic malignancy, were eligible. Exclusion criteria included infectious conditions, intestinal obstruction, severe malnutrition, American Society of Anesthesiologists (ASA) score > or =4, and postoperative stay in the intensive care unit lasting >24 h. Patients allocated to EOF received liquid diet in the first postoperative day and then regular diet. Patients received traditional feeding scheme until resolution of postoperative ileus to start liquid diet. The primary end-point of the trial was length of hospital stay. Between January 1st, 2007 and March 15th, 2008, 40 patients were randomized to receive either EOF or TOF. Hospital stay in patients who received EOF (n = 18) was 6.9 days versus 9.1 days in the TOF group (n = 22) (P = 0.022). Requirements for analgesic and antiemetic drugs, intensity of pain, intestinal function recovery, mean levels of postoperative satisfaction, postoperative complications, and quality-of-life scores did not differ between the two groups. Early resumption of oral intake is feasible and safe in gynecologic oncology patients undergoing intestinal resection as part of a planned surgical procedure. Moreover, significant reduction in length of hospital stay was demonstrated.

    Postoperative computed tomography (CT) scan patterns after colorectal resection are difficult to analyze for both clinicians and radiologists. This study aimed to assess the role of single CT scan on postoperative day 5 in predicting postoperative morbidity. From October 2007 to August 2009, 78 patients undergoing laparoscopic colorectal resection were enrolled in a research study involving a routine contrast-enhanced multi-detector CT scan on postoperative day 5. Two groups were defined: patients with intra-abdominal postoperative morbidity requiring specific management, i.e., surgical or radiological procedure, and/or antibiotic therapy ("complications" group), and patients with uneventful postoperative outcome ("uneventful" group). CT findings were compared between the two groups with Fisher's exact test or chi-square test. Postoperative abdominal complications occurred in 16 patients (21 %). Of the CT findings on day 5, pneumonia, pulmonary embolism, portal or mesenteric thrombosis, operative area fat infiltration, peritoneal effusion, pneumoperitoneum, intra-abdominal collection, parietal inflammation or collection, and subcutaneous emphysema were observed in both groups without any significant difference. Only small bowel distension [25 % (4/16) in the "complications" group vs. 5 % (3/62) in the "uneventful" group; p = 0.029] and pleural effusion [81 % (13/16) vs. 48 % (30/62); p = 0.024, respectively] were observed significantly more often in the "complications" group. This study suggested that abdominal complications cannot be predicted by a CT scan on day 5 after laparoscopic colorectal resection. Thus, it cannot be recommended for routine use.

    Sarcopenia has been proposed to be a prognostic factor of outcomes for various diseases but has not been applied to Crohn's disease (CD). We aimed to assess the impact of sarcopenia on postoperative outcomes after bowel resection in patients with CD. Abdominal computed tomography images within 30 days before bowel resection in 114 patients with CD between May 2011 and March 2014 were assessed for sarcopenia as well as visceral fat areas and subcutaneous fat areas. The impact of sarcopenia on postoperative outcomes was evaluated using univariate and multivariate analyses. Of 114 patients, 70 (61.4%) had sarcopenia. Patients with sarcopenia had a lower body mass index, lower preoperative levels of serum albumin, and more major complications (15.7% vs 2.3%, P = .027) compared with patients without sarcopenia. Moreover, predictors of major postoperative complications were sarcopenia (odds ratio [OR], 9.24; P = .04) and a decreased skeletal muscle index (1.11; P = .023). Preoperative enteral nutrition (OR, 0.13; P = .004) and preoperative serum albumin level >35 g/L (0.19; P = .017) were protective factors in multivariate analyses. The prevalence of sarcopenia is high in patients with CD requiring bowel resection. It significantly increases the risk of major postoperative complications and has clinical implications with respect to nutrition management before surgery for CD.

    The objective was to evaluate the analgesic efficacy of pre- and postoperative administration of meloxicam on the postsurgical convalescence period of lame dairy cows undergoing resection of the coffin joint. In a blinded, placebo-controlled, explorative clinical trial, 19 lame German Holstein-Friesian cows weighing 536 ± 98 kg (mean ± SD) and aged 5.7 ± 2.8 yr were included. All cows suffered from unilateral lameness due to septic arthritis of the coffin joint. Lame cows were randomly allocated to either the meloxicam group (n=9) or the control group (n=10) and received an intravenous injection of meloxicam (0.5mg/kg of BW) or an equal volume of saline immediately before surgery (d 0) and once daily from d 1 to 4. All cows received a retrograde intravenous local anesthesia (20 mL of procaine 2%) before the surgical intervention. Heart rate, respiratory rate, body temperature, plasma concentrations of cortisol, as well as production parameters (milk yield and feed intake) were evaluated from d 0 to 7. The gait of the animals was assessed daily by lameness scores and by monitoring the cows' activity by means of pedometers attached to both hind legs. Possible adverse effects on abomasal mucosal integrity were monitored by fecal occult blood tests and blood cell counts from d 0 to 7 and on d 14. Under meloxicam treatment plasma cortisol levels, lameness scores, and body temperature were significantly reduced compared with controls. While being treated with meloxicam, the time cows were standing per day was significantly longer compared with controls. In the healthy limb significantly more steps were registered in meloxicam-treated cows than in controls. Feed intake and milk yield were not significantly affected by meloxicam. No group differences were found in number of positive tests for fecal occult blood or blood cell counts. In conclusion, repeated meloxicam application demonstrated effective analgesia in the postsurgical period after resection of septically

    Changes in the portal circulatory pattern and regional hepatic blood flow (rHBF) after surgical liver resection were studied by 133 Xe-scintiphotosplenoportography (SSP). The visual patterns of pre- and postoperative portal circulation were compared. Different patterns were observed after the operation in five of 27 patients (porto-systemic shunt formation 3, progression 1, regression 1). The patients with porto-systemic shunt showed postopertive complications (massive ascites, jaundice, cardiopulmonary failure) more frequently than those without it. The ratio of rHBF increase (post-/pre-operative rHBF) was 1.36±0.63 on average. The ratio was higher in patients with good liver function or without liver cirrhosis. The ratio also correlated with the weight of the liver resected. But operation time, blood loss or whether hepatic blood supply was clamped off during the operation did not affect the ratio. Resection in the right lobe, however, caused a greater rHBF increase in the residual liver than the same degree of resection in the left lobe. SSP could be a useful method for investigating the effect of hepatic resection on portal hemodynamics and it is suggested that existence of portosystemic shunt influences the postoperative course.

    Purpose: Given the neurocognitive toxicity associated with whole-brain irradiation (WBRT), approaches to defer or avoid WBRT after surgical resection of brain metastases are desirable. Our initial experience with stereotactic radiosurgery (SRS) targeting the resection cavity showed promising results. We examined the outcomes of postoperative resection cavity SRS to determine the effect of adding a 2-mm margin around the resection cavity on local failure (LF) and toxicity. Patients and Methods: We retrospectively evaluated 120 cavities in 112 patients treated from 1998-2009. Factors associated with LF and distant brain failure (DF) were analyzed using competing risks analysis, with death as a competing risk. The overall survival (OS) rate was calculated by the Kaplan-Meier product-limit method; variables associated with OS were evaluated using the Cox proportional hazards and log rank tests. Results: The 12-month cumulative incidence rates of LF and DF, with death as a competing risk, were 9.5% and 54%, respectively. On univariate analysis, expansion of the cavity with a 2-mm margin was associated with decreased LF; the 12-month cumulative incidence rates of LF with and without margin were 3% and 16%, respectively (P=.042). The 12-month toxicity rates with and without margin were 3% and 8%, respectively (P=.27). On multivariate analysis, melanoma histology (P=.038) and number of brain metastases (P=.0097) were associated with higher DF. The median OS time was 17 months (range, 2-114 months), with a 12-month OS rate of 62%. Overall, WBRT was avoided in 72% of the patients. Conclusion: Adjuvant SRS targeting the resection cavity of brain metastases results in excellent local control and allows WBRT to be avoided in a majority of patients. A 2-mm margin around the resection cavity improved local control without increasing toxicity compared with our prior technique with no margin.

    Purpose: We sought to determine the risk of leptomeningeal disease (LMD) in patients treated with stereotactic radiosurgery (SRS) targeting the postsurgical resection cavity of a brain metastasis, deferring whole-brain radiation therapy (WBRT) in all patients. Methods and Materials: We retrospectively reviewed 175 brain metastasis resection cavities in 165 patients treated from 1998 to 2011 with postoperative SRS. The cumulative incidence rates, with death as a competing risk, of LMD, local failure (LF), and distant brain parenchymal failure (DF) were estimated. Variables associated with LMD were evaluated, including LF, DF, posterior fossa location, resection type (en-bloc vs piecemeal or unknown), and histology (lung, colon, breast, melanoma, gynecologic, other). Results: With a median follow-up of 12 months (range, 1-157 months), median overall survival was 17 months. Twenty-one of 165 patients (13%) developed LMD at a median of 5 months (range, 2-33 months) following SRS. The 1-year cumulative incidence rates, with death as a competing risk, were 10% (95% confidence interval [CI], 6%-15%) for developing LF, 54% (95% CI, 46%-61%) for DF, and 11% (95% CI, 7%-17%) for LMD. On univariate analysis, only breast cancer histology (hazard ratio, 2.96) was associated with an increased risk of LMD. The 1-year cumulative incidence of LMD was 24% (95% CI, 9%-41%) for breast cancer compared to 9% (95% CI, 5%-14%) for non-breast histology (P=.004). Conclusions: In patients treated with SRS targeting the postoperative cavity following resection, those with breast cancer histology were at higher risk of LMD. It is unknown whether the inclusion of whole-brain irradiation or novel strategies such as preresection SRS would improve this risk or if the rate of LMD is inherently higher with breast histology.

    Abdominal perineal excision (APE) has been associated with a high risk of positive circumferential resection margin (CRM+) and local recurrence rates in the treatment of rectal cancer. An alternative extralevator approach (ELAPE) has been suggested to improve the quality of resection by avoiding coning of the specimen decreasing the risk of tumor perforation and CRM+. The aim of this study is to compare the quality of the resected specimen and postoperative complication rates between ELAPE and "standard" APE. All patients between 1998 and 2014 undergoing abdominal perineal excision for primary or recurrent rectal cancer at a single Institution were reviewed. Between 1998 and 2008, all patients underwent standard APE. In 2009 ELAPE was introduced at our Institution and all patients requiring APE underwent this alternative procedure (ELAPE). The groups were compared according to pathological characteristics, specimen quality (CRM status, perforation and failure to provide the rectum and anus in a single specimen-fragmentation) and postoperative morbidity. Fifty patients underwent standard APEs, while 22 underwent ELAPE. There were no differences in CRM+ (10.6 vs. 13.6%; p = 0.70) or tumor perforation rates (8 vs. 0%; p = 0.30) between APE and ELAPE. However, ELAPE were less likely to result in a fragmented specimen (42 vs. 4%; p = 0.002). Advanced pT-stage was also a risk factor for specimen fragmentation (p = 0.03). There were no differences in severe (Grade 3/4) postoperative morbidity (13 vs. 10%; p = 0.5). Perineal wound dehiscences were less frequent among ELAPE (52 vs 13%; p < 0.01). Despite short follow-up (median 21 mo.), 2-year local recurrence-free survival was better for patients undergoing ELAPE when compared to APE (87 vs. 49%; p = 0.04). ELAPE may be safely implemented into routine clinical practice with no increase in postoperative morbidity and considerable improvements in the quality of the resected specimen of patients with low rectal

    Few studies have been designed to investigate the incidence of postoperative pneumonia after radical gastrectomy and its effect on prognosis of these patients. Incidences of postoperative pneumonia after radical gastrectomy in our department between January 1996 and December 2014 were summarized. Their effects on prognosis were retrospectively analyzed using survival curves and Cox regression. A total of 5237 patients were included in this study, 767 (14.4%) of them had complications, including 383 cases of postoperative pneumonia (7.2%). The 5-year overall and disease-specific survival of patients with postoperative pneumonia were both lower than those without this complication (P pneumonia were independent risk factors for disease-specific survival.

    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

    Perioperative nutritional support in liver surgery remains specific regarding the role of the liver in the metabolism regulation. The loss of functional liver tissue following resection procedures may result in significant metabolic disorders, particularly in patients with preoperative liver impairment in chronic conditions. Perioperative nutritional support is indicated in patients suffering from malnutrition, chronic liver disorders and also following liver resections with limiting residual parenchyma. The retrospective study assessed the effect of complete parenteral nutrition enriched with branched chain amino acids on liver function and the rate of postoperative complications following liver resections (of at least two segments) for colorectal carcinoma metastases. 142 subjects following liver resections for colorectal carcinoma metastases were included in the study. In 42 subjects with anatomical resections of at least two segments, complete parenteral nutrition enriched with branched chain amino acids (3.8 g) was administered postoperatively from Day 1. The parenteral nutrition was maintained for 5 to 7 days, from Day 3, additional oral diet regime was indicated. In 100 subjects with a single segment resections or wedge resections, a combination of glucose 10% and crystalloid solutions was administered from Day 1, and early oral diet was added from Day2. Liver tests were performed during the first postoperative week and protein electrophoresis 14 days postoperatively. During the first postoperative week, the liver test values reached normal values in patients with specialized complete parenteral nutrition. In subjects, where the specialized parenteral nutrition was not administered, increased alcaline phosphatase levels and gamma glutamyl transpherase levels were recorded through the postoperative Day 7. No significant differences were detected in protein electrophoresis values and in rates of postoperative complications (14% in both patient groups). Liver

    To establish the sufficient therapy for elderly colorectal cancer patients, we retrospectively compared postoperative Tegafur/Uracil (UFT; Taiho Pharmaceutical Co., Ltd., Tokyo, Japan) and UFT plus protein-bound polysaccharide kureha (PSK) therapies in elderly patients with resected colorectal cancer. A total of 63 patients were collected; 39 patients were administered only with UFT (control group) and 24 patients were treated with UFT+PSK (PSK group). There were no differences in patient background, surgical outcomes, and drug compliance between the two groups. The 3-year relapse-free survival rate was 47.8% in the control group and 76.2% in the PSK group (p = 0.041). The 3-year overall survival (OS) rate was 52.8% in the control group and 80.8% in the PSK group (p = 0.0498). By subset analysis, in the patients whose tumor location was the colon (p = 0.016) and whose preoperative lymphocyte percentage was below 18.7% (p = 0.017), RFS was significantly better in the PSK group. Adverse drug reactions were rarely observed. All the adverse reactions were grade 2 or below, with no severe reactions. The present retrospective study suggests a possible efficacy of postoperative adjuvant therapy with UFT plus PSK in elderly patients over 70 years of age with resected colorectal cancer.

    Despite the efficacy of postoperative adjuvant cisplatin (CDDP)-based chemotherapy for patients who have undergone surgical resection of non-small cell lung cancer (NSCLC), few reports have presented survival data for Asian patients treated with adjuvant chemotherapy involving a combination of CDDP and vinorelbine (VNR). This study was performed to evaluate the survival of patients with NSCLC who received postoperative adjuvant chemotherapy comprising CDDP + VNR. We retrospectively evaluated patients with NSCLC who received adjuvant chemotherapy comprising CDDP + VNR at the Shizuoka Cancer Center between February 2006 and October 2011. One hundred patients who underwent surgical resection of NSCLC were included in this study. The patients' characteristics were as follows: median age 63 years (range 36-74 years), female 34%, never-smokers 20%, and non-squamous NSCLC 73%. Pathological stages IIA, IIB, and IIIA were observed in 31, 22, and 47% of patients, respectively. The 5- and 2-year overall survival rates were 73 and 93%, respectively. The 5- and 2-year relapse-free survival rates were 53 and 62%, respectively. Univariate analysis of prognostic factors showed that patient characteristics (sex, histology, and pathological stage) and CDDP dose intensity were not significantly associated with survival. In 48 patients who developed NSCLC recurrence, the 5-year survival rate after recurrence was 29%, and the median survival time after recurrence was 37 months. Our results suggest that the prognosis after surgical resection of NSCLC and adjuvant chemotherapy comprising CDDP + VNR might be improving compared with previous survival data of adjuvant chemotherapy for NSCLC.

    To analyze prognostic factors for locoregional recurrence (LRR), distant metastasis (DM), and overall survival (OS) in cervical cancer patients who underwent radical hysterectomy followed by postoperative radiotherapy (PORT) in a single institute. Clinicopathologic data of 135 patients with clinical stage IA2 to IIA2 cervical cancer treated with PORT from 2001 to 2012 were reviewed, retrospectively. Postoperative parametrial resection margin (PRM) and vaginal resection margin (VRM) were investigated separately. The median treatment dosage of external beam radiotherapy (EBRT) to the whole pelvis was 50.4 Gy in 1.8 Gy/fraction. High-dose-rate vaginal brachytherapy after EBRT was given to patients with positive or close VRMs. Concurrent platinum-based chemoradiotherapy (CCRT) was administered to 73 patients with positive resection margin, lymph node (LN) metastasis, or direct extension of parametrium. Kaplan-Meier method and log-rank test were used for analyzing LRR, DM, and OS; Cox regression was applied to analyze prognostic factors. The 5-year disease-free survival was 79% and 5-year OS was 91%. In univariate analysis, positive or close PRM, LN metastasis, direct extension of parametrium, lymphovascular invasion, histology of adenocarcinoma, and chemotherapy were related with more DM and poor OS. In multivariate analysis, PRM and LN metastasis remained independent prognostic factors for OS. PORT after radical hysterectomy in uterine cervical cancer showed excellent OS in this study. Positive or close PRM after radical hysterectomy in uterine cervical cancer correlates with poor prognosis even with CCRT. Therefore, additional treatments to improve local control such as radiation boosting need to be considered.

    Purpose: To evaluate the clinical outcomes with linear accelerator-based multidose stereotactic radiosurgery (SRS) to large postoperative resection cavities in patients with large brain metastases. Methods and Materials: Between March 2005 to May 2012, 101 patients with a single brain metastasis were treated with surgery and multidose SRS (9 Gy × 3) for large resection cavities (>3 cm). The target volume was the resection cavity with the inclusion of a 2-mm margin. The median cavity volume was 17.5 cm{sup 3} (range, 12.6-35.7 cm{sup 3}). The primary endpoint was local control. Secondary endpoints were survival and distant failure rates, cause of death, performance measurements, and toxicity of treatment. Results: With a median follow-up of 16 months (range, 6-44 months), the 1-year and 2-year actuarial survival rates were 69% and 34%, respectively. The 1-year and 2-year local control rates were 93% and 84%, with respective incidences of new distant brain metastases of 50% and 66%. Local control was similar for radiosensitive (non-small cell lung cancer and breast cancer) and radioresistant (melanoma and renal cell cancer) brain metastases. On multivariate Cox analysis stable extracranial disease, breast cancer histology, and Karnofsky performance status >70 were associated with significant survival benefit. Brain radionecrosis occurred in 9 patients (9%), being symptomatic in 5 patients (5%). Conclusions: Adjuvant multidose SRS to resection cavity represents an effective treatment option that achieves excellent local control and defers the use of whole-brain radiation therapy in selected patients with large brain metastases.

    The objectives of this study were to develop a risk-adjusted model to estimate individual postoperative costs after major lung resection and to use it for internal economic audit. Variable and fixed hospital costs were collected for 679 consecutive patients who underwent major lung resection from January 2000 through October 2006 at our unit. Several preoperative variables were used to develop a risk-adjusted econometric model from all patients operated on during the period 2000 through 2003 by a stepwise multiple regression analysis (validated by bootstrap). The model was then used to estimate the postoperative costs in the patients operated on during the 3 subsequent periods (years 2004, 2005, and 2006). Observed and predicted costs were then compared within each period by the Wilcoxon signed rank test. Multiple regression and bootstrap analysis yielded the following model predicting postoperative cost: 11,078 + 1340.3X (age > 70 years) + 1927.8X cardiac comorbidity - 95X ppoFEV1%. No differences between predicted and observed costs were noted in the first 2 periods analyzed (year 2004, $6188.40 vs $6241.40, P = .3; year 2005, $6308.60 vs $6483.60, P = .4), whereas in the most recent period (2006) observed costs were significantly lower than the predicted ones ($3457.30 vs $6162.70, P < .0001). Greater precision in predicting outcome and costs after therapy may assist clinicians in the optimization of clinical pathways and allocation of resources. Our economic model may be used as a methodologic template for economic audit in our specialty and complement more traditional outcome measures in the assessment of performance.

    The objective of this study was to evaluate whether a digital thoracic drainage system (group D) is clinically useful compared with a traditional thoracic drainage system (group T) in chest tube management following anatomic lung resection. Patients scheduled to undergo segmentectomy or lobectomy were prospectively randomized before surgery to group D or T. A stratification randomization was performed according to the following air leak risk factors: age, sex, smoking status, and presence of emphysema and/or chronic obstructive pulmonary disease. The primary end point was the duration of chest tube placement. No statistically significant differences were found between groups D (n = 135) and T (n = 164) with regard to the duration of chest tube placement (median, 2.0 vs 3.0 days; P = .149), duration of hospitalization (median, 6.0 vs 7.0 days; P = .548), or frequency of postoperative adverse events (25.1% vs 20.7%; P = .361). In subgroup analyses of the 64 patients with postoperative air leak (20 in group D and 44 in group T), the duration of chest tube placement (median, 4.5 vs 4.0 days; P = .225) and duration of postoperative air leak (median, 3.0 vs 3.0 days; P = .226) were not significantly different between subgroups. The use of a digital thoracic drainage system did not shorten the duration of chest tube placement in comparison to a traditional thoracic drainage system after anatomic lung resection.

    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.

    Esophageal resection is associated with a high incidence of postoperative pneumonia. Respiratory complications account for almost half of the readmissions to the critical care unit. Postoperative complications can result in prolonged hospital stay and consequently increase healthcare costs. In cardiac surgery a preoperative inspiratory muscle training program has shown to prevent postoperative pneumonia and reduce length of hospital stay. While in some surgical centers inspiratory muscle training is already used in the preoperative phase in patients undergoing esophageal resection, the added value of this intervention on the reduction of pulmonary complications has not yet been investigated in large surgical populations other than cardiac surgery in a randomized and controlled study design. The effect of a preoperative inspiratory muscle training program on the incidence of postoperative pneumonia in patients undergoing esophageal resection will be studied in a single blind multicenter randomized controlled trial (the PREPARE study). In total 248 patients (age >18 years) undergoing esophageal resection for esophageal cancer will be included in this study. They are randomized to either usual care or usual care with an additional inspiratory muscle training intervention according to a high-intensity protocol which is performed with a tapered flow resistive inspiratory loading device. Patients have to complete 30 dynamic inspiratory efforts twice daily for 7 days a week until surgery with a minimum of 2 weeks. The starting training load will be aimed to be 60% of maximal inspiratory pressure and will be increased based on the rate of perceived exertion.The main study endpoint is the incidence of postoperative pneumonia. Secondary objectives are to evaluate the effect of preoperative inspiratory muscle training on length of hospital stay, duration of mechanical ventilation, incidence of other postoperative (pulmonary) complications, quality of life, and on

    Bronchoplastic resections emerged as an alternative to pneumonectomy for patients with impaired pulmonary function and have gained popularity due to a marked decrease in morbidity and at least similar oncological outcome. Actual guidelines recommend sleeve resections whenever technically feasible, even in cases with adequate pulmonary reserve for pneumonectomy, in order to maximally preserve functional lung parenchyma. Various suture techniques were described; the existing evidence, however, is insufficient to recommend one of them as standard. The aim of this study was to compare two suture techniques for bronchus repair after sleeve resection. Two groups of patients from two separate institutions were retrospectively analysed. In Group A (n = 20), the anastomosis was performed with a running suture at the membranous part and an interrupted suture for the rest of the circumference. In Group B (n = 40), a telescoping continuous suture was used. Intra- and postoperative findings directly related to the anastomosis were compared. The parameters were assessed as absolute numbers and percentages; the statistical significance was determined using Pearson's χ(2) test for categorical variables and Student's t-test for continuous data (P resection type (predominance of the right upper lobe for Group B), the groups were comparable regarding patient characteristics. The intraoperative anastomotic assessment revealed: patency 100% in both groups, initial air tightness (100 vs 82.5%; P = 0.047) and buttressing 85 vs 5%. No suture revision was necessary in both groups. The analysis of anastomosis-related morbidity revealed no significant difference: atelectasis (1 in Group A and 2 in Group B; P = 1), reversible anastomotic changes (0 vs 2; P = 0.309), early stenosis (0 vs 0), bronchopleural fistula (1 vs 0; P = 0.154), bronchovascular fistula (0 vs 0), late stenosis (1 vs 0; P = 0.119) and reoperations (15 vs 5%; P = 0.186). The operative mortality rate was similar (2 vs 3; P

    Anastomotic leakage (AL) is one of the most devastating complications after rectal cancer surgery. The double stapling technique has greatly facilitated intestinal reconstruction especially for anastomosis after low anterior resection (LAR). Risk factor analyses for AL after open LAR have been widely reported. However, a few studies have analyzed the risk factors for AL after laparoscopic LAR. Laparoscopic rectal surgery provides an excellent operative field in a narrow pelvic space, and enables total mesorectal excision surgery and preservation of the autonomic nervous system with greater precision. However, rectal transection using a laparoscopic linear stapler is relatively difficult compared with open surgery because of the width and limited performance of the linear stapler. Moreover, laparoscopic LAR exhibits a different postoperative course compared with open LAR, which suggests that the risk factors for AL after laparoscopic LAR may also differ from those after open LAR. In this review, we will discuss the risk factors for AL after laparoscopic LAR.

    Full Text Available Gabapentin is well known for its pain control and antiepileptic effect, but its antiemetic effect is poorly investigated. Here we report on effective gabapentin use for refractory vomiting after craniotomy in two children with medulloblastoma in the fourth ventricle. The two pediatric patients (an 11-year-old girl and a 4-year-old boy underwent near-total excision of the tumor via craniotomy. Both patients suffered from refractory postoperative nausea and vomiting, treated with multiple traditional antiemetic drugs but without relief. After gabapentin intake, their nausea and vomiting improved from one to two episodes per day to complete resolution of symptoms. This report suggests that gabapentin may be a novel antiemetic therapeutic intervention for patients with refractory nausea and vomiting after craniotomy.

    Full Text Available AIM:To discuss the long-term postoperative results of bilateral lateral rectus recession (BLR and unilateral lateral rectus recession-medial rectus resection (RR in therapy of intermittent exotropia.METHODS: We retrospectively analyzed 213 cases of intermittent exotropia who underwent surgery between 2008 and 2010. The patients were grouped into BLR group and RR group. Motor outcomes were divided into three groups on the basis of the angle of deviation after surgery:overcorrection (esotropia/phoria >5△, orthophoria (esotropia/phoria ≤5△to exotropia/phoria ≤10△, and undercorrection/recurrence (exotropia/phoria>10△. Titmus test was used to evaluate stereoacuity, the stereoacuity <800s of arc meaned the patients had stereopsis. Surgical outcome including motor criteria and sensory status were compared at postoperative 6, 12, 24mo and at 36mo examination between groups.RESULTS:At 12, 24mo after surgery, the motor outcomes had no difference (P>0.05 between groups. However, the motor outcomes at 6, 36mo were signally different in each group, indicating the success rate in RR group at 6mo was higher than that in BLR group (83.02% vs 82.24%, P<0.05 but the result was contrary at the 3y examination (60.75% vs 43.40%, P<0.05. No statistical significance were found in the sensory outcomes between the groups at mean of 3.7y follow-up.CONCLUSION:Themotor outcomes in RR group were better than in BLR group at 6mo after surgery, while the 3y outcomes were better in BLR group. This may be due to the recurrence rate of the BLR was lower than the RR group’s.

    Purpose: To determine the potential role for adjuvant proton-based radiotherapy (PT) for resected pancreatic head cancer. Methods and Materials: Between June 2008 and November 2008, 8 consecutive patients with resected pancreatic head cancers underwent optimized intensity-modulated radiotherapy (IMRT) treatment planning. IMRT plans used between 10 and 18 fields and delivered 45 Gy to the initial planning target volume (PTV) and a 5.4 Gy boost to a reduced PTV. PTVs were defined according to the Radiation Therapy Oncology Group 9704 radiotherapy guidelines. Ninety-five percent of PTVs received 100% of the target dose and 100% of the PTVs received 95% of the target dose. Normal tissue constraints were as follows: right kidney V18 Gy to <70%; left kidney V18 Gy to <30%; small bowel/stomach V20 Gy to <50%, V45 Gy to <15%, V50 Gy to <10%, and V54 Gy to <5%; liver V30 Gy to <60%; and spinal cord maximum to 46 Gy. Optimized two- to three-field three-dimensional conformal proton plans were retrospectively generated on the same patients. The team generating the proton plans was blinded to the dose distributions achieved by the IMRT plans. The IMRT and proton plans were then compared. A Wilcoxon paired t-test was performed to compare various dosimetric points between the two plans for each patient. Results: All proton plans met all normal tissue constraints and were isoeffective with the corresponding IMRT plans in terms of PTV coverage. The proton plans offered significantly reduced normal-tissue exposure over the IMRT plans with respect to the following: median small bowel V20 Gy, 15.4% with protons versus 47.0% with IMRT (p = 0.0156); median gastric V20 Gy, 2.3% with protons versus 20.0% with IMRT (p = 0.0313); and median right kidney V18 Gy, 27.3% with protons versus 50.5% with IMRT (p = 0.0156). Conclusions: By reducing small bowel and stomach exposure, protons have the potential to reduce the acute and late toxicities of postoperative chemoradiation in this setting.

    Esophagectomy remains the most reliable technique for managing esophageal cancer, but anastomotic complications including postoperative leak, ischemia and stricture negatively affect outcomes of this specific surgery. The aim of this study was to evaluate the effects of a novel method of esophagogastric anastomosis for reducing postoperative dysphagia and stricture formation. Eighty patients who were scheduled for esophagectomy due to esophageal cancer were randomly assigned into two groups: intervention and control (40 each). In the control group, the esophagogastric anastomosis was performed with a linear gastric incision, whilst in the intervention group a new method of disc-shaped gastric resection for anastomosis was applied. Postoperative outcomes were compared between the two groups. The incidence of postoperative dysphagia and anastomotic stricture was significantly lower in the disc-shaped resection group (dysphagia 45% vs 75%, P = 0.02; stricture 12.5% vs 32.5%, P = 0.03), whilst the length of stay in an intensive care unit (ICU), anastomotic leakage and other complications were not significantly different between the two groups (all P > 0.05). Anastomotic complications can be reduced by improving surgical techniques. The decreased incidence of postoperative dysphagia and anastomotic stricture in our study may be partly due to providing the proper diameter for the site of anastomosis when using the disc-shaped gastric resection method. Hence, this new method can improve the clinical outcomes of patients who undergo esophagectomy with esophagogastric anastomosis. © The Author(s) 2016.

Classification of COPD severity was based on guidelines of the Global Initiative for Chronic Obstructive Lung Disease (GOLD. Characteristics among the three subgroups were compared and recurrence-free survivals were analyzed.Results: A total of 172 patients were diagnosed with COPD (124 as GOLD-1, 46 as GOLD-2, and two as GOLD-3. The frequencies of recurrence were significantly higher in patients with higher COPD grades (P<0.001. Recurrence-free survival at 5 years was 78.1%, 70.4%, and 46.4% in non-COPD, mild COPD, and moderate/severe COPD groups, respectively (P<0.001. By univariate analysis, the age, sex, smoking history, COPD severity, tumor size, histology, and pathological stage were associated with recurrence-free survival. Multivariate analysis showed that older age, male, moderate/severe COPD, and advanced stage were independent risk factors associated with recurrence-free survival.Conclusion: NSCLC patients with COPD are at high risk for postoperative recurrence, and moderate/severe COPD is an independent unfavorable prognostic factor.

    Full Text Available Introduction. Laparoscopic liver resection is considered risky in cirrhotic patients, even if minor surgical trauma of laparoscopy could be useful to prevent deterioration of a compromised liver function. This study aimed to identify the differences in terms of perioperative complications and early outcome in cirrhotic patients undergoing minor hepatic resection for hepatocellular carcinoma with open or laparoscopic technique. Methods. In this retrospective study, 156 cirrhotic patients undergoing liver resection for hepatocellular carcinoma were divided into two groups according to type of surgical approach: laparoscopy (LS group: 23 patients or laparotomy (LT group: 133 patients. Perioperative data, mortality, and length of hospital stay were recorded. Results. Groups were matched for type of resection, median number of nodules, and median diameter of largest lesions. Groups were also homogeneous for preoperative liver and renal function tests. Intraoperative haemoglobin decrease and transfusions of red blood cells and fresh frozen plasma were significantly lower in LS group. MELD score lasted stable after laparoscopic resection, while it increased in laparotomic group. Postoperative liver and renal failure and mortality were all lower in LS group. Conclusions. Lower morbidity and mortality, maintenance of liver function, and shorter hospital stay suggest the safety and benefit of laparoscopic approach.

    To analyze treatment outcomes and patterns of recurrence, and to examine the impact of adjuvant postoperative radiotherapy (PORT) after esophagectomy in esophageal squamous cell carcinoma (SqCC) regarding the status of circumferential resection margin (CRM). We performed a retrospective review of esophageal cancer patients operated in Seoul National University Hospital between 2003 and 2010. Pathologically proven T3 SqCC patients with written reports mentioning the status of CRM were selected. Fifty-nine out of 71 patients (83.1%) had CRM+. Twenty-eight patients had radiotherapy in CRM+ and CRM-, respectively. The median follow-up period was 17.1 months (range: 5.2-63.1). Median survival and 2-year overall survival were 13.8 months and 41.9% in CRM+, and 27.3 months and 74.1% in CRM-, respectively. Loco-regional relapse-free survival (LRRFS) rate at 2 years was 33.6% and 74.1% in each groups (P = 0.029). Loco-regional recurrence was the major pattern of failure in CRM+. PORT did not improve LRRFS. The esophageal SqCC patients with CRM+ after resection showed worse LRRFS. This finding validated the prognostic value of CRM status. Nevertheless, we failed to demonstrate the benefits of adjuvant PORT in CRM+. This might suggest the necessity of neoadjuvant therapy to decrease the CRM+ rate after esophagectomy.

    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.

    Patient and disease-related factors, as well as operation technique all have the potential to impact on postoperative outcome in Crohn's disease. The available evidence is based on small series and often displays conflicting results. To investigate the effect of pre- and intra-operative risk factors on 30-day postoperative outcome in patients undergoing surgery for Crohn's disease. International prospective snapshot audit including consecutive patients undergoing right hemicolectomy or ileocaecal resection. This study analysed a subset of patients who underwent surgery for Crohn's disease. The primary outcome measure was the overall Clavien-Dindo postoperative complication rate. The key secondary outcomes were anastomotic leak, re-operation, surgical site infection and length of stay at hospital. Multivariable binary logistic regression analyses were used to produce odds ratios (OR) and 95% confidence intervals (CI). Three hundred and seventy five resections in 375 patients were included. The median age was 37 and 57.1% were female. In multivariate analyses, postoperative complications were associated with preoperative parenteral nutrition (OR 2.36 95% CI 1.10-4.97)], urgent/expedited surgical intervention (OR 2.00, 95% CI 1.13-3.55) and unplanned intraoperative adverse events (OR 2.30, 95% CI 1.20-4.45). The postoperative length of stay in hospital was prolonged in patients who received preoperative parenteral nutrition (OR 31, CI [1.08-1.61]) and those who had urgent/expedited operations (OR 1.21, CI [1.07-1.37]). Preoperative parenteral nutritional support, urgent/expedited operation and unplanned intraoperative adverse events were associated with unfavourable postoperative outcome. Enhanced preoperative optimization and improved planning of operation pathways and timings may improve outcomes for patients. This article is protected by copyright. All rights reserved.

    Purpose: To evaluate the efficacy of postoperative adjuvant radiotherapy (RT) for positive resection margin and/or pathologic T3 (pT3) adenocarcinoma of the prostate with undetectable postoperative prostate-specific antigen (PSA) levels. Methods and materials: We retrospectively analyzed 125 patients with a positive resection margin and/or pT3 adenocarcinoma of the prostate who had undetectable postoperative serum PSA levels after radical prostatectomy. Seventy-three patients received postoperative adjuvant RT and 52 did not. Follow-up ranged from 1.5 to 12.0 years (median 4.2 for the irradiated group and 4.9 for the nonirradiated group). PSA outcome was available for all patients. Freedom from failure was defined as the maintenance of a serum PSA level of ≤0.2 ng/mL, as well as the absence of clinical local recurrence and distant metastasis. Results: No difference was found in the 5-year actuarial overall survival between the irradiated and nonirradiated group (94% vs. 95%). However, patients receiving adjuvant RT had a statistically superior 5-year actuarial relapse-free rate, including freedom from PSA failure, compared with those treated with surgery alone (88% vs. 65%, p=0.0013). In the irradiated group, 8 patients had relapse with PSA failure alone. None had local or distant recurrence. In the nonirradiated group, 15, 1, and 2 had PSA failure, local recurrence, and distant metastasis, respectively. On Cox regression analysis, pre-radical prostatectomy PSA level and adjuvant RT were statistically significant predictive factors for relapse, and Gleason score, extracapsular invasion, and resection margin status were not. There was a suggestion that seminal vesicle invasion was associated with an increased risk of relapse. The morbidity of postoperative adjuvant RT was acceptable, with only 2 patients developing Radiation Therapy Oncology Group Grade 3 genitourinary complications. Adjuvant RT had a minimal adverse effect on urinary continence and did not cause

    Loco-regional and distant relapses contribute to impair the outcome of rectal cancer patients. As to the former, either pre-or post-operative radiation therapy (RT) significantly reduce loco-regional recurrence; post-operative chemotherapy (CT), alone or in different combinations with RT, is effective in improving both disease-free survival and survival. However, many drawbacks still exist regarding the method of RT delivery as well as the toxicity of combination adjuvant chemotherapy. The aim of this trial is to assess the effectiveness and toxicity of adjuvant post-operative RT vs combined RT and CT (5-FU plus levamisole) in patients with TNM stage II-III resectable rectal cancer (pT3-4, pN0, M0; pT1-4, pN1-3, M0). The primary endpoint is overall survival; secondary endpoints are disease-free survival rate of loco-regional recurrence, and treatment-related toxicity/morbidity. (author).

    Full Text Available Objective: To study the effect of surgical resection combined with transcatheter arterial chemoembolization (TACE on postoperative serum tumor marker levels and stem cell characteristics during tumor recurrence. Methods: A total of 98 patients with liver cancer who received radical resection in our hospital between May 2013 and July 2015 were reviewed and divided into TACE group and control group according to whether they received TACE within two months after surgical resection. Serum levels of tumor markers were detected 4 weeks after operation; the tumor recurrence was followed up within 3 years after operation, and the expression of stem cell marker molecules and cell proliferation molecules in recurrent lesions were detected. Results: 4 weeks after radical hepatectomy, serum AFP, AFP-L3, GP73 and GPC3 levels in TACE group were significantly lower than those in control group; Nanog, CD133, EpCAM, PICK1, CyclinD1, C-myc and Survivin expression in surgically removed lesions of TACE group were not different from those of control group while Nanog, CD133, EpCAM, PICK1, CyclinD1, C-myc and Survivin expression in recurrent lesions were significantly lower than those of control group. Conclusion: Surgical resection combined with TACE can more effectively remove liver cancer lesions, reduce the tumor marker levels and inhibit the tumor stem cell characteristics and cell proliferation activity in recurrent lesions.

    To evaluate the impact of rectal balloon (RB) inflation on post-transurethral resection of the prostate (TURP) bleeding in patients with symptomatic benign prostatic hyperplasia. After institutional review board approval, patients who were eligible for TURP were randomized into two equal groups, depending on whether they received postoperative endorectal balloon (RB) (GII) or not (GI). The tip of three-way Foley catheter was fixed to a balloon by a blaster strip to prepare air-tight RB. Postoperatively, the RB was inflated for 15 minutes by a pressure-controlled sphygmomanometer. Perioperative data were compared between both groups, including hemoglobin (Hb) deficit 24-hour postoperatively and at time of discharge. Functional outcomes, anorectal complaints, and adverse events were assessed perioperatively and after 1 and 3 months. Fifty patients were enrolled, including 13 (26%) patients who presented with indwelling urethral catheters. Baseline data and mean resected tissue weight were comparable between both groups, including preoperative Hb (p = 0.17). Immediate postoperative Hb deficit was, comparable between GI and GII patients (0.58 ± 0.18 vs 0.60 ± 0.2, p = 0.56) before RB inflation, respectively. However, compared to GI patients, mean Hb deficit significantly decreased in GII patients 24-hour postoperatively (0.2 ± 0.2 vs 0.7 ± 0.3 g, p = 0.002) and at time of discharge (0.8 ± 0.2 vs 1.3 ± 0.4 g, p = 0.003). GII patients needed significantly less postoperative irrigation (2.1 ± 1.6 vs 8.3 ± 1.8 L, p inflation seems to be simple, safe, and an efficient procedure to reduce postoperative bleeding and irrigation volume. It is significantly associated with shorter catheterization time and hospital stay.

    Background Postoperative pulmonary and shoulder complications are important causes of postoperative morbidity following thoracotomy. While physiotherapy aims to prevent or minimise these complications, currently there are no randomised controlled trials to support or refute effectiveness of physiotherapy in this setting. Methods/Design This single blind randomised controlled trial aims to recruit 184 patients following lung resection via open thoracotomy. All subjects will receive a preoperative physiotherapy information booklet and following surgery will be randomly allocated to a Treatment Group receiving postoperative physiotherapy or a Control Group receiving standard care nursing and medical interventions but no physiotherapy. The Treatment Group will receive a standardised daily physiotherapy programme to prevent respiratory and musculoskeletal complications. On discharge Treatment Group subjects will receive an exercise programme and exercise diary to complete. The primary outcome measure is the incidence of postoperative pulmonary complications, which will be determined on a daily basis whilst the patient is in hospital by a blinded assessor. Secondary outcome measures are the length of postoperative hospital stay, severity of pain, shoulder function as measured by the self-reported shoulder pain and disability index, and quality of life measured by the Medical Outcomes Study Short Form 36 v2 New Zealand standard version. Pain, shoulder function and quality of life will be measured at baseline, on discharge from hospital, one month and three months postoperatively. Additionally a subgroup of subjects will have measurement of shoulder range of movement and muscle strength by a blinded assessor. Discussion Results from this study will contribute to the increasing volume of evidence regarding the effectiveness of physiotherapy following major surgery and will guide physiotherapists in their interventions for patients following thoracotomy.

    Surgical treatment of carcinoma of the distal third of the rectum with anal sphincter preservation is increasingly used in accredited cancer centers. This study aimed to evaluate the diagnostic usefulness of radiological investigations in the management of patients who had undergone resection with coloanal anastomosis for carcinoma of the rectum, in the immediate post-operative period, during closure of the protective colostomy and in the follow-up of symptomatic recanalized patients. A total of 175 patients who had undergone total rectal resection with end-to-side anastomosis for carcinoma of the distal third of the rectal ampulla, most of whom had received postoperative radiotherapy, were evaluated radiologically. In the postoperative period radiological investigation was ordered only for symptomatic patients to detect pathology of the anastomosis and the pouch sutures and was used direct film abdominal radiography and contrast-enhanced radiography of the rectal stump with a water-soluble radio-opaque agent. Before closure of the colostomy, 2 months after rectal excision or approximately 4 months after if postoperative radiotherapy was given, the anastomosis and pouch of all patients, even asymptomatic ones, were studied with water-soluble contrast enema to check for normal canalization. In the follow-up after recanalization radiological examinations were done to complete the study of the large intestine if the endoscopist was not able to examine it up to the cecum. Of the 175 patients examined radiologically during the postoperative period and/or subsequent follow-up, 95 showed no pathological findings. Seventy-nine patients had fistulas of the coloanal anastomosis or the pouch, 23 of which supplied a presacral collection. In the absence of severe sepsis, the only therapeutic measures were systemic antibiotics and washing of the surgical catheters to maintain efficient operation.

    Full Text Available ABSTRACT: Introduction & Objective: Transurethral Resection of Prostate (TURP is usually performed under regional or general anesthesia. An alternative to conventional anesthesia is performing of TURP under local anesthetic infiltration with sedation. The aim of this study was to evaluate the efficacy and complication of sedoanalgesia in TURP. Material & Methods: In a prospective clinical trial from September 2006 to December 2007, 60 patients (30 in each group with prostate hypertrophy, candidate for TURP, were randomly assigned into two groups. In the first group, standard spinal anesthesia was done. In the second group, five minutes before the operation, 25 mgs of diazepam plus 25-50 mgs of pethedine was intravenously administered followed by injection of 10 ml lidocaine 2% gel in the urethra and the skin in the suprapubic area was anesthetized with 2 ml of 1% lidocaine. Using a 22 gauge nephrostomy needle, the suprapubic skin was punctured and the needle was directed toward prostate apex and 10-20ml of 1% lidocaine was injected at the serosal aspect of the rectal wall. For dorsal nerve block, 5-10ml of 1% lidocaine was injected at penopubic junction, and then a standard TURP was performed. Patients were switched to another anesthetic technique if the selected technique failed. Severity of pain was assessed by visual analogue scale. Results: The average prostate size was 25 grs (range10-50grs in the local anesthetic group (group 1 and 27.5 grs (range 10-50 grs in the spinal group (group2. In the local anesthetic group, 82.3% had no or mild pain while moderate to severe pain was reported in 16, 7% of the patients. In the group with spinal anesthesia, these were 93.1% and 6.9% respectively. Intolerable pain was observed in 23.3% and 13.8% of groups 1 and 2 respectively (p>0.05.

    To investigate the association between preoperative fecal organic acid concentrations and the incidence of postoperative infectious complications in patients undergoing major hepatectomy with extrahepatic bile duct resection for biliary malignancies. The fecal samples of 44 patients were collected before undergoing hepatectomy with bile duct resection for biliary malignancies. The concentrations of fecal organic acids, including acetic acid, butyric acid, and lactic acid, and representative fecal bacteria were measured. The perioperative clinical characteristics and the concentrations of fecal organic acids were compared between patients with and without postoperative infectious complications. Among 44 patients, 13 (30%) developed postoperative infectious complications. Patient age and intraoperative bleeding were significantly greater in patients with postoperative infectious complications compared with those without postoperative infectious complications. The concentrations of fecal acetic acid and butyric acid were significantly less, whereas the concentration of fecal lactic acid tended to be greater in the patients with postoperative infectious complications. The calculated gap between the concentrations of fecal acetic acid plus butyric acid minus lactic acid gap was less in the patients with postoperative infectious complications (median 43.5 vs 76.1 μmol/g of feces, P = .011). Multivariate analysis revealed that an acetic acid plus butyric acid minus lactic acid gap acid profile (especially low acetic acid, low butyric acid, and high lactic acid) had a clinically important impact on the incidence of postoperative infectious complications in patients undergoing major hepatectomy with extrahepatic bile duct resection.

    We report a rare case of intractable bile leakage after liver resection due to stenosis of the anastomosis of a choledochojejunostomy after pancreaticoduodenectomy. A 65-year-old woman was diagnosed with pancreatic and right breast cancer, and underwent pancreaticoduodenectomy and right mastectomy with simultaneous axillary lymph node dissection. Adjuvant chemotherapy and follow-up were performed in our department. After 18 months, computed tomography revealed a liver metastasis of 2.5 cm in segment 8. Because the primary nest of liver metastasis was unknown and performing a biopsy was difficult due to the location, partial resection of the liver was performed. Pathological examination confirmed liver metastasis from the breast cancer. She was rehospitalized due to a right subdiaphragmatic abscess 33 days post-surgery. Abscess drainage revealed bile leakage, and the cause was believed to be stenosis of the anastomosis created by the choledochojejunostomy. Percutaneous transhepatic cholangiographic drainage was performed, and the bile leakage disappeared immediately. However, it was difficult to release the anastomotic stenosis by choledochoscopy; therefore, a retrograde drainage tube was placed in the hepatic duct using enteroscopy, and it formed an internal fistula. The patient has continued to undergo chemotherapy for recurrence in the remnant liver that was observed 16 months after the hepatectomy. In conclusion, when hepatic resection is performed after pancreaticoduodenectomy, attention should be paid to the possible occurrence of bile leakage.

    Gastrointestinal recovery is a critical milestone after bowel resection with postoperative ileus resulting in increased risk of complications and prolonged hospitalization. The aim of this study is to evaluate the efficacy and safety of ulimorelin, a ghrelin receptor agonist given postoperatively in 2 identically designed phase 3 studies (ClinicalTrials.gov NCT01285570 and NCT01296620). This investigation is designed as a multicenter, double-blind, randomized, parallel-group study. This study involves hospital inpatients. Adult patients undergoing partial bowel resection were included. Thirty-minute intravenous infusions (160 µg/kg, 480 µg/kg ulimorelin, or placebo) once daily were started within 60 minutes after the end of surgery and ended at the first of the following: primary efficacy end point fulfilled (defined below), hospital discharge, or 7 days treatment. The primary efficacy end point was the time from the end of surgery to the composite end point of the later of first bowel movement and tolerance of solid food. Safety was assessed with the use of standard assessments including adverse events and laboratory tests. Ulimorelin Study of Efficacy and Safety 007, n = 332 patients; Ulimorelin Study of Efficacy and Safety 008, n = 330 patients: in both studies, the primary efficacy end point and the secondary efficacy outcomes, which included postsurgical time to first bowel movement, tolerance of solid food, and discharge eligibility, did not differ significantly among patients treated with either dose of ulimorelin versus placebo. Rates of serious adverse events were comparable across all treatment groups. There was no statistically significant difference from placebo in regard to events of interest, namely nausea, vomiting, ileus as an adverse event, nasogastric tube reinsertion, anastomotic complications, and infections. A possible limitation is the variance inherent in surgery and comorbidities. Although the efficacy of ulimorelin in reducing the

    Radiotherapy is an effective treatment for the postoperative loco-regional recurrence of esophageal cancer; however, the optimal treatment field remains controversial. This study aims to evaluate the outcome of local field radiotherapy without elective nodal irradiation for postoperative loco-regional recurrence of esophageal cancer. We retrospectively investigated 35 patients treated for a postoperative loco-regional recurrence of esophageal cancer with local field radiotherapy between December 2008 and March 2016. The median irradiation dose was 60 Gy (range: 50-67.5 Gy). Thirty-one (88.6%) patients received concurrent chemotherapy. The median follow-up period was 18 months (range: 5-94 months). The 2-year overall survival was 55.7%, with a median survival time of 29.9 months. In the univariate analysis, the maximal diameter ≤20 mm (P = 0.0383), solitary lesion (P = 0.0352), and the complete remission after treatment (P = 0.00411) had a significantly better prognosis. A total of 27 of 35 patients (77.1%) had progressive disease (loco-regional failure [n = 9], distant metastasis [n = 7], and both loco-regional failure and distant metastasis [n = 11]). No patients had Grade 3 or greater mucositis. Local field radiotherapy is a considerable treatment option for postoperative loco-regional recurrence of esophageal cancer. © The Author 2017.

    Novel local anesthetic blocks have become increasingly popular in the multimodal pain management following abdominal surgery, but have not been evaluated in a procedure-specific manner in colorectal surgery. This study aims to evaluate the efficacy of novel local anesthetic techniques in colorectal surgery. Electronic literature search of PubMed, EMBASE, and Cochrane databases (date range, January 1990 to February 2013) STUDY SELECTION: Randomized controlled trials comparing a novel local anesthetic technique with placebo/routine analgesia in adults undergoing open or laparoscopic colonic or rectal resection were selected. This is a meta-analysis of randomized controlled trials evaluating novel local anesthetic wound infiltration techniques such as wound catheter, transversus abdominis plane block, and intraperitoneal instillation in colorectal surgical procedures. The comparator group was defined as placebo/routine analgesia. The primary outcome was opiate requirement at 24 hours. Secondary outcomes included opiate requirements at 48 hours, pain numerical rating score at 24 and 48 hours at rest and on movement, recovery (length of stay, nausea and vomiting, time until bowel movement and diet resumption), and complications. Subgroup analysis was performed to evaluate specific local anesthetic techniques and open and laparoscopic surgery. Twelve randomized controlled trials compared local anesthetic techniques with placebo/routine analgesia. Local anesthetic techniques demonstrated a significant reduction in opiate requirement at 48 hours. Local anesthetic techniques were also associated with lower pain scores on movement at 24 and 48 hours, shorter length of stay, and earlier resumption of diet. The diverse study design led to statistical heterogeneity in several analyses. Novel local anesthetic wound infiltration techniques in colorectal surgery appear to reduce opiate requirements, to reduce pain scores, and to improve recovery in comparison with placebo

    Full Text Available Abstract Background It is difficult for neurosurgeons to perceive the complex three-dimensional anatomical relationships in the sellar region. Methods To investigate the value of using a virtual reality system for planning resection of sellar region tumors. The study included 60 patients with sellar tumors. All patients underwent computed tomography angiography, MRI-T1W1, and contrast enhanced MRI-T1W1 image sequence scanning. The CT and MRI scanning data were collected and then imported into a Dextroscope imaging workstation, a virtual reality system that allows structures to be viewed stereoscopically. During preoperative assessment, typical images for each patient were chosen and printed out for use by the surgeons as references during surgery. Results All sellar tumor models clearly displayed bone, the internal carotid artery, circle of Willis and its branches, the optic nerve and chiasm, ventricular system, tumor, brain, soft tissue and adjacent structures. Depending on the location of the tumors, we simulated the transmononasal sphenoid sinus approach, transpterional approach, and other approaches. Eleven surgeons who used virtual reality models completed a survey questionnaire. Nine of the participants said that the virtual reality images were superior to other images but that other images needed to be used in combination with the virtual reality images. Conclusions The three-dimensional virtual reality models were helpful for individualized planning of surgery in the sellar region. Virtual reality appears to be promising as a valuable tool for sellar region surgery in the future.

    Ileocolonoscopy allows early detection of recurrence after surgical resection for Crohn's disease [CD]. Plexitis, defined as presence of inflammatory cells in or around enteric ganglia or nerve bundles, in the proximal surgical margin has been associated with an increased overall recurrence risk. We investigated prospectively whether plexitis can predict endoscopic recurrence [ER] in a consecutive cohort of CD patients undergoing ileocolonic resection. All CD patients undergoing ileocolonic resection in our institution between October 2009 and December 2012 were eligible for this study. Clinical data were obtained prospectively from the patients' files, and biopsies from the proximal surgical margins were analysed immunohistochemically for inflammation at the myenteric and submucosal plexus [lymphocytes, mast cells, eosinophils]. The degree of plexitis was correlated with the presence of ER at 6 months, defined as a modified Rutgeerts' score of ≥ i2b. Multivariate models were developed and tested to predict posterior probability of ER. A total of 74 patients were included. Six months after ileocolonic resection, 50% showed ER. Known risk factors such as penetrating disease, previous resections, and active smoking, showed no relation with ER. On the other hand, submucosal lymphocytic plexitis was associated with ER [p = 0.020]. The predictive value of lymphocytic cell count increased with more extensive biopsy sampling and with application of immunohistochemistry. Submucosal lymphocytic plexitis in the proximal surgical margin was significantly related with a higher risk for ER after ileocolonic resection. These data support development of a postoperative prevention trial with vedolizumab, which may block lymphocytic trafficking in the postoperative bowel.

    Purpose: The role of adjuvant chemoradiotherapy (CRT) in D2-resected gastric-cancer patients has not been defined yet. We investigated the effect of postoperative chemoradiotherapy on the relapse rate and survival rate of patients with D2-resected gastric cancer. Methods and Materials: From August 1995 to April 2001, 544 patients received postoperative CRT after curative D2 resection. During the same period of time, 446 patients received surgery without further adjuvant treatment. The adjuvant CRT consisted of 400 mg/m 2 of fluorouracil plus 20 mg/m 2 of leucovorin for 5 days, followed by 4,500 cGy of radiotherapy for 5 weeks, with fluorouracil and leucovorin on the first 4 and the last 3 days of radiotherapy. Two 5-day cycles of fluorouracil and leucovorin were given 4 weeks after the completion of radiotherapy. Results: The median duration of overall survival was significantly longer in the CRT group than in the comparison group (95.3 months vs. 62.6 months), which corresponds to a hazard ratio for death of 0.80 (p = 0.0200) or a reduction of 20% in the risk of death in the CRT group. The 5-year survival rates were consistently longer in the CRT group at Stages II, IIIA, IIIB, and IV than those in the comparison group. The CRT was associated with increases in the median duration of relapse-free survival (75.6 months vs. 52.7 months; hazard ratio for relapse, 0.80, p = 0.0160). Conclusion: Our results highly suggest that the postoperative chemoradiotherapy in D2-resected gastric-cancer patients can prolong survival and decrease recurrence

    With the use of the operating microscope, a variety of malignant as well as benign lesions of the pineal region can be excised safely. In cases in which complete excision is impossible, obtaining tissue for a histological diagnosis has been extremely helpful in planning appropriate postoperative radiotherapy and chemotherapy. Reducing tumor bulk may also be beneficial, as has been shown to be the case in medulloblastoma. As adjunctive modes of therapy for malignant pineal tumors become available, such as chemotherapy and possibly immunotherapy, the authors believe that the burden will be on the neurosurgeon to provide a tissue diagnosis. Complete myelography should be considered preoperatively or postoperatively to detect asymptomatic meningeal implants. The presence of such metastases makes postoperative craniospinal irradiation essential. The authors advocate liberal dosages of corticosteroids (i.e. 10-20 mg dexamethasone/day) for 24-48 hr prior to surgery. The authors recommend postoperative radiotherapy in all patients with malignant pineal region lesions regardless of whether or not complete excision was possible. The lowest incidence of recurrence in the literature seems to occur following 5,000-5,500 rads. In the face of negative myelography and CSF cytology, there is controversy regarding prophylactic spinal axis irradiation. The use of chemotherapy and/or radiotherapy is probably the initial therapy of choice in such a patient. Following this, if a small, localized tumor burden remains, it can be removed surgically, as is done with localized residual tumor in testicular cancer. Failure to adequately assess the presence of meningeal seeding by cytology and melography may make certain patients vulnerable to spinal recurrence of disease in the face of complete local remission

    postoperative complications (C1-2: 71%; SA: 22%; p = 0.03). Both local and distant tumor recurrence was greatest for C1-2 tumors (local C1-2: 29%; local SA: 11%; distant C1-2: 14%; distant SA: 0%). Statistical analysis of tumor recurrence based on tumor location was not possible due to the small number of cases. There was no between-groups difference in exposure to postoperative adjuvant radiotherapy. There was no difference in median survival between groups receiving proton beam radiotherapy or intensity-modulated radiotherapy versus no radiation therapy (p = 0.8). Compared with en bloc resection of chordomas involving the subaxial cervical spine, en bloc resection of chordomas involving the upper cervical spine (C1-2) is associated with poorer outcomes, such as less favorable margins, higher rates of complications, and increased tumor recurrence. Data from this cohort do not support a statistically significant difference in survival for patients with C1-2 versus subaxial disease, but larger studies are needed to further study survival differences.

    Dutch national guidelines on the diagnosis and treatment of gastric cancer recommend the use of perioperative chemotherapy in patients with resectable gastric cancer. However, adjuvant chemotherapy is often not administered. The aim of this study was to evaluate hospital variation on the probability to receive adjuvant chemotherapy and to identify associated factors with special attention to postoperative complications. All patients who received neoadjuvant chemotherapy and underwent an elective surgical resection for stage IB-IVa (M0) gastric adenocarcinoma between 2011 and 2015 were identified from a national database (Dutch Upper GI Cancer Audit). A multivariable linear mixed model was used to evaluate case-mix adjusted hospital variation and to identify factors associated with adjuvant therapy. Of all surgically treated gastric cancer patients who received neoadjuvant chemotherapy (n = 882), 68% received adjuvant chemo(radio)therapy. After adjusting for case-mix and random variation, a large hospital variation in the administration rates for adjuvant was observed (OR range 0.31-7.1). In multivariable analysis, weight loss, a poor health status and failure of neoadjuvant chemotherapy completion were strongly associated with an increased likelihood of adjuvant therapy omission. Patients with severe postoperative complications had a threefold increased likelihood of adjuvant therapy omission (OR 3.07 95% CI 2.04-4.65). Despite national guidelines, considerable hospital variation was observed in the probability of receiving adjuvant chemo(radio)therapy. Postoperative complications were strongly associated with adjuvant chemo(radio)therapy omission, underlining the need to further reduce perioperative morbidity in gastric cancer surgery.

    The aim of this study was to determine whether postoperative radiation therapy (PORT) is associated with an overall survival (OS) benefit in patients with completely resected Masaoka or Masaoka-Koga stage II and III thymoma. All patients with completely resected (R0) stage II or III thymoma were identified in a large database of the International Thymic Malignancy Interest Group. Clinical, pathologic, treatment, and follow-up information were extracted. OS was the primary end point. A univariate analysis using the log-rank test was performed, and a multivariate Cox model was created to identify factors associated with OS. Of 1263 patients meeting the selection criteria, 870 (69%) had stage II thymoma. The WHO histologic subtype was A/AB in 360 patients (30%) and B1/B2/B3 in 827 (70%). PORT was given to 55% of patients (n = 689), 15% (n = 180) received chemotherapy, and 10% (n = 122) received both. The 5- and 10-year OS rates for patients having undergone an operation plus PORT were 95% and 86%, respectively, compared with 90% and 79% for patients receiving an operation alone (p = 0.002). This OS benefit remained significant when patients with stage II (p = 0.02) and stage III thymoma (p = 0.0005) were analyzed separately. On multivariate analysis, earlier stage, younger age, absence of paraneoplastic syndrome, and PORT were significantly associated with improved OS. We observed an OS benefit with the use of PORT in completely resected stage II and III thymoma. In the absence of a randomized trial, this represents the most comprehensive analysis of individual patient data and strong evidence in favor of PORT in this patient population.

    Adjuvant chemotherapy for resected rectal cancer is widely used. However, studies on adjuvant treatment following neoadjuvant chemoradiotherapy (CRT) and total mesorectal excision (TME) have yielded conflicting results. Recent studies have focused on adding oxaliplatin to both preoperative and postoperative therapy, making it difficult to assess the impact of adjuvant oxaliplatin alone. This study was aimed at determining the impact of (i) any adjuvant treatment and (ii) oxaliplatin-containing adjuvant treatment on disease-free survival in CRT-pretreated, R0-resected rectal cancer patients. Patients undergoing R0 TME following 5-fluorouracil (5FU)-only-based CRT between January 1, 2008, and December 31, 2010, were selected from a nationwide registry. After propensity score matching (PSM), comparison of disease-free survival (DFS) using Kaplan-Meier analysis and log-rank test was performed in (i) patients receiving no vs. any adjuvant treatment and (ii) patients treated with adjuvant 5FU/capecitabine without vs. with oxaliplatin. Out of 1497 patients, 520 matched pairs were generated for analysis of no vs. any adjuvant treatment. Mean DFS was significantly prolonged with adjuvant treatment (81.8 ± 2.06 vs. 70.1 ± 3.02 months, p rectal cancer patients treated with neoadjuvant CRT and TME surgery under routine conditions, adjuvant chemotherapy significantly improved DFS. No benefit was observed for the addition of oxaliplatin to adjuvant chemotherapy in this setting.

    This study aims to assess the feasibility of acupuncture and a Pericardium 6 (PC6) wristband as an add-on intervention of antiemetic medication for the prevention of postoperative nausea and vomiting (PONV) in patients undergoing elective laparoscopic colorectal cancer resection. A total of 60 participants who are scheduled to undergo elective laparoscopic resection of colorectal cancer will be recruited. An enhanced recovery after surgery protocol using standardised antiemetic medication will be provided for all participants. Participants will be equally randomised into acupuncture plus PC6 wristband (Acupuncture), PC6 wristband alone (Wristband), or no acupuncture or wristband (Control) groups using computer-generated random numbers concealed in opaque, sealed, sequentially numbered envelopes. For the acupuncture combined with PC6 wristband group, the embedded auricular acupuncture technique for preoperative anxiolysis and up to three sessions of acupuncture treatments with manual and electrical stimulation within 48 hours after surgery will be provided by qualified Korean medicine doctors. The PC6 wristband will be applied in the Acupuncture and Wristband groups, beginning 1 hour before surgery and lasting 48 hours postoperatively. The primary outcome will be the number of participants who experience moderate or severe nausea, defined as nausea at least 4 out of 10 on a severity numeric rating scale or vomiting at 24 hours after surgery. Secondary outcomes, including symptom severity, participant global assessments and satisfaction, quality of life, physiological recovery, use of medication and length of hospital stay, will be assessed. Adverse events and postoperative complications will be measured for 1 month after surgery. All participants will provide written informed consent. The study has been approved by the institutional review board (IRB). This pilot trial will inform a full-scale randomised trial of acupuncture combined with PC6 stimulation

    (NIPEC-LT) gemcitabine for 6 months postoperatively is suggested as a new treatment that has demonstrated decreases in local-regional failure and promises to more adequately target micrometastases in the peritoneal space, in the liver and lymph nodes. Pancreas cancer surgery should attempt to achieve negative margins of resection with the removal of at least 12 lymph nodes. Hyperthermic intraperitoneal gemcitabine can adequately eradicate malignant cells dislodged from the cancer specimen into the bed of the resection at high density and on distant peritoneal surfaces as peritoneal metastases. Long-term intraperitoneal gemcitabine may act on micrometastases in the liver through absorption into the portal vein blood and the lymph nodes as a result of gemcitabine absorption by subperitoneal lymphatic channels. The use of HIPEC and NIPEC-LT gemcitabine may improve local control of resected pancreas cancer. Copyright © 2017 Elsevier Ltd. All rights reserved.

    To highlight on the versatility of superiorly based pedicled gastrocnemius muscle flap in the limb-sparing surgery for bone or soft tissue sarcoma around the knee and popliteal fossa. Patients and Methods: A total of 30 patients with localized bone or soft tissue sarcoma around the knee and popliteal fossa were treated with limb-salvage procedure. The study included 5 cases with bone sarcoma of the distal femur, 15 cases having bone sarcoma of proximal tibia and 10 cases having soft tissue sarcoma around the knee region and popliteal fossa. Routine preoperative staging studies were done for every patient and included local plain radiography, local MRI, isotopic bone scan and CT chest. Local MRA or angiography was done in selected cases. According to the Enneking staging system, 19 patients had stage IIB and 11 had stage IIA. Patients having bone sarcoma of the proximal tibia were subjected to wide resection, endo prosthetic reconstruction and reconstruction of the extensor mechanism by the medial gastrocnemius muscle flap. Patients having bone sarcoma of the distal femur were subjected to wide resection, endo prosthetic reconstruction and coverage of the prosthesis and re balance of the patellar tendon by the medial gas-trocnemius flap. Patients having soft tissue sarcoma were subjected to wide resection and soft tissue coverage with either medial or lateral myocutaneous gastrocnemius flap or muscle flap with grafting. Limb function was evaluated according to MSTS functional scores. Adjuvant chemotherapy or radiotherapy was given according to nationally agreed protocols. Results: There were 18 males and 12 females with a mean age of 29 years at the time of surgery (range 11-44 years). The mean follow-up period was 52 months (range 25-72 months). Resection with a negative bony and soft tissue margins could be achieved in all cases. A total of 30 flaps were used and included medial gastrocnemius muscle flaps in 21 cases (15 cases had proximal tibia endoprothesis, 5

    Surgical resection of lung cancer is frequently required in patients with severely impaired lung function resulting from chronic obstructive pulmonary disease. Twenty patients with obstructive lung disease and cancer (mean preoperative forced expiratory volume in 1 second [FEV1] . 1.73 L) were studied preoperatively and postoperatively by spirometry and radionuclide perfusion, single-breath ventilation, and washout techniques to test the ability of these methods to predict preoperatively the partial loss of lung function by the resection. Postoperative FEV1 and forced vital capacity (FVC) were accurately predicted by the formula: postoperative FEV1 (or FVC) . preoperative FEV1 X percent function of regions of lung not to be resected (r . 0.88 and 0.95, respectively). Ventilation and perfusion scans are equally effective in prediction. Washout data add to the sophistication of the method by permitting the qualitative evaluation of ventilation during tidal breathing. Criteria for patients requiring the study are suggested

    To evaluate the accuracy of craniomaxillofacial resections performed with an image-guided surgical sagittal saw. Twenty-four craniomaxillofacial resections were performed using an image-guided sagittal saw. Surgical outcomes were compared with a preoperative virtual plan in terms of the resected bone volume, control point position and osteotomy trajectory angle. Each measurement was performed twice by two independent observers. The best convergence between the planned and actual bone resection was observed for the orbital region (6.33 ± 4.04%). The smallest mean difference between the preoperative and postoperative control point positions (2.00 ± 0.66 mm) and the lowest mean angular deviation between the virtual and actual osteotomy (5.49 ± 3.17 degrees) were documented for the maxillary region. When all the performed procedures were analyzed together, mean difference between the planned and actual bone resection volumes was 9.48 ± 4.91%, mean difference between the preoperative and postoperative control point positions amounted to 2.59 ± 1.41 mm, and mean angular deviation between the planned and actual osteotomy trajectory equaled 8.21 ± 5.69 degrees. The results of this study are encouraging but not fully satisfactory. If further improved, the hereby presented navigation technique may become a valuable supporting method for craniomaxillofacial resections.

    PURPOSE To assess corneal microarchitecture and regional epithelial thickness profile in eyes with keratoconus, postoperative corneal ectasia, and normal unoperated eyes using spectral-domain optical coherence tomography (SD OCT). METHODS Regional corneal epithelial thickness profiles of eyes with keratoconus (KC) and postoperative corneal ectasia (Ectasia) were measured with anterior segment SC OCT (Optovue RTVue-100, Optovue Inc., Fremont, CA) and compared retrospectively to those of normal eyes (Control). Epithelial thickness was assessed at 21 points, 0.5 mm apart, across the central 6-mm of the corneal apex in the horizontal and vertical meridians. RESULTS One hundred twenty eyes were evaluated, including 49 eyes from 29 patients with KC, 32 eyes from 16 patients with Ectasia, and 39 eyes from 21 control patients. Average epithelial thickness at the corneal apex was 41.18±6.47μm (range 30 to 51 μm) in eyes with KC, 46.5±6.72μm in eyes with ectasia (range 34 to 60 μm), and 50.45±3.92 μm in normal eyes (range 42 to 55 μm). Apical epithelial thickness was significantly thinner in eyes with KC (p ectasia (p=.0007) than it was in controls. Epithelial thickness ranges in all other areas varied widely for KC (SD, range 21 to 101 μm) and ectasia (SD, range 30 to 82 μm) compared to controls (SD, range 43 to 64), p = .0063 CONCLUSION Central epithelial thickness was, on average, significantly thinner in ectatic corneas compared to controls; however, both central and regional epithelial thickness was highly irregular and variable in corneas with keratoconus and postoperative corneal ectasia. These thickness variations may alter preoperative topographic features and measurements in unpredictable ways, especially steepest K values. Regional epithelial thickness cannot be assumed to be uniform in ectatic corneas and therefore may require direct measurement when considering treatments for which underlying stromal thickness is particularly important, such as

    Currently, there is limited evidence to support the safety of neuraxial catheters in neonates. Safety concerns have been cited as a major barrier to performing large randomized trials in this population. The main objective of this study is to examine the safety of neuraxial catheters in neonates across multiple institutions. Specifically, we sought to determine the incidence of overall and individual complications encountered when neuraxial catheters were used for postoperative analgesia in neonates. This was an observational study that used the Pediatric Regional Anesthesia Network database. Complications and adverse events were defined by the presence of at least 1 of the following intraoperative and/or postoperative factors: catheter malfunction (dislodgment/occlusion), infection, block abandoned (unable to place), block failure (no evidence of block), vascular (blood aspiration/hematoma), local anesthetic systemic toxicity, excessive motor block, paresthesia, persistent neurologic deficit, and other (e.g., intra-abdominal misplacement, tremors). Additional analyses were performed to identify the use of potentially toxic doses of local anesthetics. The study cohort included 307 neonates with a neuraxial catheter. There were 41 adverse events and complications recorded, resulting in an overall incidence of complications of 13.3% (95% confidence interval, 9.8%-17.4%). Among the complications, catheter malfunction, catheter contamination, and vascular puncture were common. None of the complications resulted in long-term complications and/or sequelae, resulting in an estimated incidence of any serious complications of 0.3% (95% confidence interval, 0.08%-1.8%). There were 120 of 307 patients who received intraoperative and/or postoperative infusions consistent with a potentially toxic local anesthetic dose in neonates. The incidence of potentially toxic local anesthetic infusion rates increased over time (P = 0.008). Neuraxial catheter techniques for intraoperative

    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.

    Approximately 15-30 % of surgical procedures involving the lumbar spine are associated with complications that require further diagnostic work-up. The choice of imaging modality for postoperative complications depends on the extent, pattern and temporal evolution of the postoperative neurological signs and symptoms as well as on the preoperative clinical status, the surgical procedure itself and the underlying pathology. The interpretation of imaging findings, in particular the distinction between postoperative complications and normally expected nonspecific postoperative imaging alterations can be challenging and requires the integration of clinical neurological information and the results of laboratory tests. The combination of different imaging techniques might help in cases of equivocal imaging results. (orig.)

    Preoperative differential diagnosis of gastric submucosal tumors has generally been difficult because they are covered with normal mucosa. However, recent advances in endoscopic ultrasound (EUS)-guided sampling of submucosal gastrointestinal lesions have made it possible to achieve preoperative differential diagnosis of gastric submucosal tumors. A 76-year-old woman was referred to our hospital with a gastric submucosal tumor. The tumor was observed in the antrum of the stomach. It was preoperatively diagnosed as a schwannoma after immunohistochemical evaluation of a biopsy specimen, obtained using endoscopic ultrasound-guided fine needle aspiration. A computed tomography scan of the abdomen revealed lymphadenopathies near the tumor indicating the possibility of lymph node metastasis from the gastric tumor. The patient underwent laparoscopic distal gastrectomy with D1 + lymph node dissection. The resected tumor was a submucosal tumor measuring 65 × 45 × 35 mm; it was histopathologically diagnosed as a schwannoma. Resected lymph nodes were enlarged in the absence of lymph node metastasis as a result of reactive lymphadenopathy. A definitive preoperative diagnosis of gastric schwannoma is possible using immunohistochemical staining techniques and EUS-guided sampling techniques. After definitive preoperative diagnosis of gastric schwannoma, minimal surgery is recommended to achieve R0 resection.

  19. Gabapentin Does Not Appear to Improve Postoperative Pain and Sleep Patterns in Patients Who Concomitantly Receive Regional Anesthesia for Lower Extremity Orthopedic Surgery: A Randomized Control Trial

    Full Text Available In recent years, gabapentin has gained popularity as an adjuvant therapy for the treatment of postoperative pain. Numerous studies have shown a decrease in pain score, even with immediate postoperative activity, which is significant for early post-op ambulation and regaining functionality sooner. However, studies have been in conclusive in patients undergoing lower extremity orthopedic surgery. For this reason, we hoped to study the effect of gabapentin on postoperative pain in patients undergoing total knee arthroplasty, total hip arthroplasty, or a hip fracture repair. This was done in the setting of ensuring adequate postoperative analgesia with regional blocks and opioid PCA, as is protocol at our institution. Given the sedative effects of gabapentin and the potential for improving postoperative sleep patterns, we also studied the drug’s effect on this aspect of our patient’s postoperative course. We utilized the Pittsburg Sleep Quality Index and Visual Analog Scale for pain to obtain a more objective standardized score amongst our study population. Our results indicate that gabapentin does not offer any additional relief in pain or improve sleep habits in patients who have received either a femoral or lumbar plexus block for lower extremity orthopedic surgery. This trial is registered with NCT01546857.

    A 60-year-old man underwent palliative surgery with a diagnosis of unresectable cancer, and he visited our hospital for further treatment. Since the cancer was unresectable and multiple hepatic tumors were revealed in CT images that were not metastases, we decided to perform curative surgery for the pancreatic cancer accompanied by partial liver invasion. Pancreaticoduodenectomy plus partial hepatectomy were performed, and 2 tumors were detected in the resected specimen: one in the pancreas-duodenum region and a submucosal tumor in the duodenum bulb. The large tumor that occupied the pancreasduodenum region was histologically diagnosed as an undifferentiated carcinoma, and the duodenal submucosal tumor was consistent with findings of a poorly differentiated adenocarcinoma. Two years after surgery, CT examination revealed a mass extending into the inferior vena cava(IVC)from near the right renal vein. We eventually diagnosed lymph node recurrence with tumor thrombosis inthe IVC and started chemotherapy(FOLFIRINOX). After the tumor decreased, we performed salvage surgery involving resection of the lymph node, thrombectomy, and right nephrectomy. The tumor revealed atypical cells in the region of thrombosis, and the pathological findings were not in conflict with the findings of metastases from pancreatic cancer 2 years prior. After the treatment, chemotherapy was administered and he survived without any recurrence for 15 months after surgery.

    Laparoscopic resection of stomach was done in 84 patients with complicated peptic ulcer of stomach and duodenum. There were 1.2% post-operative complications in case of laparoscopic resection of stomach in comparison with open resection, which had 33.3% complications. There were not deaths in case of laparoscopic resection of stomach. This indication was about 4% in patients after open resection. It was determined that functionalefficiency afterlaparoscopic resection was in 1.6-1.8 times higher than afteropen resectionof stomach.

    To assess corneal microarchitecture and regional epithelial thickness profile in eyes with keratoconus, postoperative corneal ectasia (ectasia), and normal unoperated eyes (controls) using spectral-domain optical coherence tomography (SD-OCT). Regional corneal epithelial thickness profiles were measured with anterior segment SD-OCT (Optovue RTVue-100, Optovue Inc., Fremont, CA). Epithelial thickness was assessed at 21 points, 0.5 mm apart, across the central 6-mm of the corneal apex in the horizontal and vertical meridians. One hundred twenty eyes were evaluated, including 49 eyes from 29 patients with keratoconus, 32 eyes from 16 patients with ectasia, and 39 eyes from 21 control patients. Average epithelial thickness at the corneal apex was 41.18 ± 6.47 μm (range: 30 to 51 μm) for keratoconus, 46.5 ± 6.72 μm for ectasia (range: 34 to 60 μm), and 50.45 ± 3.92 μm for controls (range: 42 to 55 μm). Apical epithelial thickness was significantly thinner in eyes with keratoconus (P ectasia (P = .0007) than in controls. Epithelial thickness ranges in all other areas varied widely for keratoconus (range: 21 to 101 μm) and ectasia (range: 30 to 82 μm) compared to controls (range: 43 to 64) (P = .0063). SD-OCT demonstrated significant central and regional epithelial thickness profile differences between keratoconus, ectasia, and control eyes, with significant variability and unpredictability in ectatic eyes. This regional irregularity may necessitate direct epithelial thickness measurement for treatments where underlying stromal variations may be clinically relevant, including corneal collagen cross-linking or topography-guided ablations.

    The employment of surgery as a single treatment modality for patients with resectable locally advanced head and neck squamous cell carcinoma (HNSCC) has been associated with high rates of locoregional recurrences even after adequate resection. The addition of postoperative radiotherapy (RT) as adjuvant to surgical resection for advanced HNSCC was investigated in an effort to decrease locoregional failure rates and improve treatment outcome. The unsatisfactory results in terms of locoregional control (LRC) and survival rates achieved with postoperative RT in patients with high-risk features have led to the necessity of exploring the role of concurrent chemotherapy in the adjuvant treatment in resectable advanced HNSCC with confirmed presence of high-risk pathological features. Two prospective randomized independent trials designed and conducted by Radiation Therapy Oncology Group (RTOG) and the European Organization for Research and Treatment of Cancer (EORTC) demonstrated that the addition of cisplatin-based chemotherapy improved LRC and disease-free survival (DFS). Significant improvement in overall survival (OS) with the use of postoperative concurrent chemoradiotherapy (CCRT) was observed in the EORTC trial. High-risk pathological features in patients with resected head and neck cancer representing adverse prognostic factors that are predictive for local and/or regional recurrence are related to the primary tumor and/or metastatic lymph nodes in the neck. Extracapsular extension (ECE) of nodal disease in the neck has been confirmed as a high-risk pathological feature negatively influencing LRC and survival in patients treated with either postoperative RT or postoperative CCRT. This article reviews the historical progress in the management of resectable locally advanced HNSCC and the impact of ECE on clinical outcome in patients treated with adjuvant therapy following surgery. It can be concluded that strong evidence exists for an improved outcome for high

    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.

    Pancreatectomy with arterial resection for locally advanced pancreatic duct adenocarcinoma (PDA) is associated with high morbidity and is thus considered as a contraindication. The aim of our study was to report our experience of pancreatectomy with planned arterial resection for locally advanced PDA based on specific selection criteria. All patients receiving pancreatectomy for PDA between October 2008 and July 2014 were reviewed. The patients were classified into group 1, pancreatectomy without vascular resection (66 patients); group 2, pancreatectomy with isolated venous resection (31 patients), and group 3, pancreatectomy with arterial resection for locally advanced PDA (14 patients). The primary selection criteria for arterial resection was the possibility of achieving a complete resection based on the extent of axial encasement, the absence of tumor invasion at the origin of celiac trunk (CT) and superior mesenteric artery (SMA), and a free distal arterial segment allowing reconstruction. Patient outcomes and survival were analyzed. Six SMA, two CT, four common hepatic artery, and two replaced right hepatic artery resections were undertaken. The preferred arterial reconstruction was splenic artery transposition. Group 3 had a higher preoperative weight loss, a longer operative time, and a higher incidence of intraoperative blood transfusion. Ninety-day mortality occurred in three patients in groups 1 and 2. There were no statistically significant differences in the incidence, grade, and type of complications in the three groups. Postoperative pancreatic fistula and postpancreatectomy hemorrhage were also comparable. In group 3, none had arterial wall invasion and nine patients had recurrence (seven metastatic and two loco-regional). Survival and disease-free survival were comparable between groups. Planned arterial resection for PDA can be performed safely with a good outcome in highly selected patients. Key elements for defining the resectability is based on

    Sternal resection is occasionally required for patients with malignant tumors, particularly sarcomas, in the sternal region. Few reports have described post-operative respiratory and shoulder function after sternal resection for patients with bone and soft-tissue sarcomas. Eight consecutive patients with bone and soft tissue sarcomas requiring sternal resection were the focus of this study. Chest wall was reconstructed with a non-rigid or semi-rigid prosthesis combined, in most cases, with soft tissue flap reconstruction. Clinical outcomes investigated included complications, shoulder function, evaluated with Musculoskeletal Tumor Society-International Symposium of Limb Salvage system, and respiratory function, evaluated by use of spirometry. The anterior chest wall was reconstructed with non-rigid strings for 3 patients and with polypropylene mesh for 5. There were no severe post-operative complications, for example surgical site infection or pneumonia. All 3 patients with non-rigid reconstruction experienced paradoxical breathing, whereas none with polypropylene mesh did so. Post-operatively, FEV(1)% was unchanged but %VC was significantly reduced (p = 0.01), irrespective of the reconstruction method used (strings or polypropylene mesh). Shoulder function was not impaired. Among patients undergoing sternal resection, post-operative shoulder function was excellent. Pulmonary function was slightly restricted, but not sufficiently so to interfere with the activities of daily living (ADL). Paradoxical breathing is a slight concern for non-rigid reconstruction.

    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.

    To determine brain plasticity changes due to resective epilepsy surgery in children, we performed a longitudinal connectome analysis on the pattern of axonal connectivity in the contralateral hemisphere. Pre- and postoperative diffusion tensor imaging (DTI) data were acquired from 35 children with intractable focal epilepsy. A total of 54 brain regions of interest (ROIs) were generated in the hemisphere contralateral to the resection. Within a 54 × 54 connectivity matrix, a pairwise connectivity score was calculated for each connection between two ROIs, based on the DTI fiber streamline number in each connection. A permuted Spearman's ρ-rank analysis was used to identify specific inter-regional connections showing a significant association between the postoperative change of connectivity score and clinical variables. Nineteen connections in the contralateral hemisphere showed postoperative increases in the strength of connectivity. Postoperative increase in connectivity between insular-inferior frontal operculum regions as well as that between superior frontal orbital and mid frontal orbital regions were both significantly associated with a larger surgical resection volume (ρ > +0.40) and a younger patient age (ρ > -0.34). These increases were more robust in patients with frontal resection and in those achieving seizure freedom. Neuropsychological evaluation on subsets of patients revealed that such increases in connectivity were associated with preserved or improved cognitive functions such as visual memory and planning. Resective epilepsy surgery may lead to increased contralateral axonal connectivity in children with focal epilepsy. Our data lead to a hypothesis that such increased connectivity may be an imaging marker of postoperative brain plasticity to compensate for cognitive function.

    Full Text Available Background: Spinal anesthesia is the technique of choice in transurethral resection of prostate (TURP. The major complication of spinal technique is risk of hypotension. Saddle block paralyzed pelvic muscles and sacral nerve roots and hemodynamic derangement is less. Aims and objectives: To compare the hemodynamic changes and adequate surgical condition between saddle block and subarachnoid block for TURP. Material and methods: Ninety patients of aged between 50 to 70 years of ASA-PS I, II scheduled for TURP were randomly allocated into 2 groups of 45 in each group. Group A patients were received spinal (2 ml of hyperbaric bupivacaine and Group B were received saddle block (2 ml of hyperbaric bupivacaine. Baseline systolic, diastolic and mean arterial pressure, heart rate, oxygen saturation were recorded and measured subsequently. The height of block was noted in both groups. Hypotension was corrected by administration of phenylephrine 50 mcg bolus and total requirement of vasopressor was noted. Complications (volume overload, TURP syndrome etc. were noted. Results: Incidence of hypotension and vasopressor requirement was less (P < 0.01 in Gr B patients.Adequate surgical condition was achieved in both groups. There was no incidence of volume overload, TURP syndrome, and bladder perforation. Conclusion: TURP can be safely performed under saddle block without hypotension and less vasopressor requirement.

    Twenty-four patients who had undergone radical pancreatic resection were evaluated by CT one week to 11 years after surgery. Eighteen patients had had the Whipple procedure; six had had total pancreatectomy. The region between the aorta and superior mesenteric artery, previously occupied by the uncinate process of the pancreas, is an important area to evaluate for tumor recurrence because periampullary tumors tend to metastasize to the lymph nodes in this region. Tumor recurrence here is readily detectable by CT since radical pancreatectomy leaves this area area free of soft tissue attenuation material. CT demonstrated postoperative complications or tumor recurrence in 16 of the 24 patients and was 100% accurate in patients who had follow-up.

    To analyze the clinicopathologic factors related to recurrence and metastasis of stage II or III colon cancer after radical resection. The clinical and pathological data of 628 patients with stage II or III colon cancer after radical resection from Jan. 2005 to Dec. 2008 in our hospital were retrospectively reviewed and analyzed. The overall recurrence and metastasis rate was 28.5% (179/628). The 5-year disease-free survival (DFS) rate was 70.3% and 5-year overall survival (OS) rate was 78.5%. Univariate analysis showed that age, smoking intensity, depth of tumor invasion, lymph node metastasis, TNM stage, gross classification, histological differentiation, blood vessel tumor embolus, tumor gross pathology, multiple primary tumors, preoperative and postoperative serum concentration of CEA and CA19-9, and the regimen of adjuvant chemotherapy were correlated to recurrence and metastasis of colon cancer after radical resection. Multivariate analysis showed that regional lymph node metastasis, TNM stage, the regimen of postoperative adjuvant chemotherapy, and preoperative serum concentration of CEA and CA19-9 were independent factors affecting the prognosis of colon cancer patients. Regional lymph node metastasis, TNM stage, elevated preoperative serum concentration of CEA and CA19-9, the regimen of postoperative adjuvant chemotherapy with single fluorouracil type drug are independent risk factors of recurrence and metastasis in patients with stage II-III colon cancer after radical resection.

    The aim of this study was to evaluate the results of postoperative radiotherapy in a case of perihilar cholagiocarcinoma by analyzing overall survival rate, patterns of failure, prognostic factors for overall survival, and toxicity. Between January 1998 and March 2008, 38 patients with perihilar cholangiocarcinoma underwent a surgical resection and adjuvant radiotherapy. The median patient age was 59 years (range, 28 to 72 years), which included 23 men and 15 women. The extent of surgery was complete resection in 9 patients, microscopically positive margins in 25 patients, and a subtotal resection in 4 patients. The tumor bed and regional lymphatics initially received 45 Gy or 50 Gy, but was subsequently boosted to a total dose of 59.4 Gy or 60 Gy in incompletely resected patients. The median radiotherapy dose was 59.4 Gy. Concurrent chemotherapy was administered in 30 patients. The median follow-up period was 14 months (range, 6 to 45 months). The 3-year overall survival and 3-year progression free survival rates were 30% and 8%, respectively. The median survival time was 28 months. A multivariate analysis showed that differentiation was the only significant factor for overall survival. The 3-year overall survival was 34% in R0 patients and 20% in R1 patients. No statistically significant differences in survival were found between the 2 groups (p=0.3067). The first site of failure was local in 18 patients (47%). No patient experienced grade 3 or higher acute toxicity and duodenal bleeding developed in 2 patients. Our results suggest that adjuvant RT might be a significant factor in patients with a positive margin following a radical resection. However, there was still a high locoregional recurrence rate following surgery and postoperative radiotherapy. Further study is necessary to enhance the effect of the adjuvant radiotherapy.

    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.

    A review was performed on entero-cutaneous fistula (ECF) repair and early recurrence, adding our twenty adult patients (65% had multiple fistulas). The search yielded 4.098 articles but only 15 were relevant: 1.217 patients underwent surgery. The interval time between fistula's diagnosis and operative repair was between 3 months and 1 year. A bowel resection with primary anastomosis was performed in 1.048 patients, 192 (18.3%) underwent a covering stoma: 856 patients (81.7%) had a fistula takedown in one procedure. The patients had 14.3% recurrence and 13.1% mortality rate. In our experience 75% were surgically treated after a period equal or above one year from fistula occurrence: surgery was very demolitive (in 40% remnant small bowel was less than 100 cm). We performed a bowel resection with a hand-sewn anastomosis (95%) without temporary stoma. In-hospital mortality was 0% and at discharge all were back to oral intake with 0% early re-fistulisation. Literature supports our experience: ECF takedown could be safely performed after an adequate period of recovery from 3 months to one year from fistula occurrence. In our series primary repair (bowel resection plus reconnection surgery without temporary stoma) avoided an early recurrence without mortality.

    NSQIP Risk Calculator was developed to allow surgeons to inform their patients about their individual risks for surgery. Its ability to predict complication rates and length of stay (LOS) has made it an appealing tool for both patients and surgeons. However, the NSQIP Risk Calculator has been criticized for its generality and lack of detail towards surgical subspecialties, including the hepatopancreaticobiliary (HPB) surgery. We wish to determine whether the NSQIP Risk Calculator is predictive of post-operative complications and LOS with respect to Whipple's resections for our patient population. As well, we wish to identify strategies to optimize early surgical outcomes in patients with pancreatic cancer. We conducted a retrospective review of patients who underwent elective Whipple's procedure for benign or malignant pancreatic head lesions at Health Sciences North (Sudbury, Ontario), a tertiary care center, from February 2014 to August 2016. Comparisons of LOS and post-operative complications between NSQIP-predicted and actual ones were carried out. NSQIP-predicted complications rates were obtained using the NSQIP Risk Calculator through pre-defined preoperative risk factors. Clinical outcomes examined, at 30 days post-operation, included pneumonia, cardiac events, surgical site infection (SSI), urinary tract infection (UTI), venous thromboembolism (VTE), renal failure, readmission, and reoperation for procedural complications. As well, mortality, disposition to nursing or rehabilitation facilities, and LOS were assessed. A total of 40 patients underwent Whipple's procedure at our center from February 2014 to August 2016. The average age was 68 (50-85), and there were 22 males and 18 females. The majority of patients had independent baseline functional status (39/40) with minimal pre-operative comorbidities. The overall post-operative morbidity was 47.5% (19/40). The rate of serious complication was 17.5% with four Clavien grade II, two grade III, and one grade

    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.

  1. General versus regional anaesthesia for cataract surgery: effects on neutrophil apoptosis and the postoperative pro-inflammatory state.

    At clinically relevant concentrations, volatile anaesthetic agents influence neutrophil function. Our hypothesis was that sevoflurane would inhibit neutrophil apoptosis and consequently influence the postoperative pro-inflammatory state. In order to identify selectively the effect of the anaesthetic agent sevoflurane, we studied patients undergoing minimally stimulating (cataract) surgery randomly allocated to receive either sevoflurane (n = 11) or local anaesthesia (n = 12). Venous blood samples were taken immediately prior to anaesthesia and at 1, 8 and 24 h thereafter. The rate of neutrophil apoptosis, plasma concentration of cytokines and differential white cell count were measured. The rates of neutrophil apoptosis and plasma concentrations of IL-1beta, TNF-alpha and IL-8 at each time point were similar in the two groups. IL-6 concentrations increased significantly and to a similar extent compared to preanaesthetic levels at 8 and 24 h. This study demonstrates that sevoflurane does not influence the rate of neutrophil apoptosis, cytokine concentrations and neutrophil count following cataract surgery.

    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

    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.

    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.

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.

    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.

    closed pleural drainage (0.5-in multiperforated chest tube in the postoperative period following pulmonary resection (lobectomy, segmentectomy and pulmonary nodule resection were evaluated. The decision for chest tube removal followed clinical criteria defined by the surgical team, who did not participate in the study. Vital capacity, pain intensity (using a visual analog pain scale and the distance covered on the six-minute walk test were determined 30 min prior to and 30 min after the removal of the chest tube. The statistical analysis was performed using paired t-tests, and the level of significance was set at 0.05. RESULTS: After the removal of the chest tube, the visual analog scale pain scores were significantly lower (3.46 cm vs. 1.77 cm; p = 0.001 and the distance covered on the six-minute walk test was significantly higher (374.34 m vs. 444.62 m; p = 0.03. Vital capacity prior to and after chest tube removal was not significantly affected (2.15 L and 2.25 L, respectively; p = 0.540. CONCLUSIONS: The results of the present study suggest that the presence of a chest tube is a factor significantly associated with postoperative pain and functional limitation in patients submitted to pulmonary resection.

    From January 1978 through December 1982, a total of 241 cases with lung cancer underwent surgery. Twenty-nine cases (operative death: 7, relative non-curative operation: 13, exploratory thoracotomy: 9) were excluded because they did not receive radiation therapy (RT). The remaining 212 cases were available for this analysis. Forty-two of them were treated with RT postoperatively. Three-year survival rates according to curability in the non-RT and RT groups were 83 % and 71 % (NS) in the curative operation group. In the relatively curative operation group, the corresponding figures were 40 % and 33 % (NS), and in the absolutely non-curative operation group, 3 % and 20 % (p < 0.01), respectively. The analysis of background factors revealed that in the curative operation group the rate of combined resection and in the relatively curative operation group pT3 and combined resection were significantly higher in the RT group than non-RT group. In the absolutely non-curative operation group, the rate of pM1 was significantly lower in RT group than the non-RT group. The pattern of failure of the RT group by histology was analysed. Local and regional failure was most common in the squamous cell carcinoma group and distant failure in the adenocarcinoma group. However, in the adenocarcinoma group local and regional or supraclavicular lymph node failure was also frequently noted. The relationship between the radiation field and local and regional or supraclavicular lymph node failure was analysed. In the squamous cell carcinoma group, in-field failure was most common, whereas in the adenocarcinoma group, outside (marginal) failure was common, especially in the supraclavicular lymph nodes. Concerning squamous cell carcinoma, microscopic or macroscopic residual tumor at the surgical margin, which includes the chest wall, stump (BS or VS) and pericardium was well controlled in each operation group with more than 50 Gy of RT.

  10. 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.

    The right prefrontal lobe has not traditionally been considered eloquent brain. Resection of tumours within this region does not typically lead to permanent functional impairment. In this report, we highlight the case of a patient who developed autobiographical memory loss following an uncomplicated resection of a right prefrontal tumour. A previously fit and well 15-year old presented with a persistent right-sided headache. An MRI demonstrated an expanded right mid-frontal gyrus with changes consistent with a low-grade tumour. The patient underwent a right-sided craniotomy and resection of the lesion which was confirmed as a WHO grade II diffuse astrocytoma. Postoperatively, the patient reported profound retrograde amnesia for a range of memory components, in particular autobiographical memory and semantic memory. Postoperative imaging showed a good resection margin with no evidence of underlying brain injury. Over an 18-month period, the patient showed no improvement in autobiographical memory; however, significant relearning of semantic knowledge took place and her academic performance was found to be in line with expectations for her age. In this report, we discuss a case and review the literature on the role of the right prefrontal cortex in memory and caution on the perception of right prefrontal non-eloquence.

    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.

    2008-01-01

    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.

    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.

    Focal cortical dysplasia type IIb (FCD IIb) lesions are highly epileptogenic and frequently cause pharmacoresistant epilepsy. Complete surgical resection leads to seizure freedom in most cases. However, the term "complete" resection is controversial with regard to the necessity of performing resections of the subcortical zone, which is frequently seen in these lesions on magnetic resonance imaging (MRI). We retrospectively analyzed 50 epilepsy patients with histologically proven FCD IIb. The extent of surgical resection was determined by SPM5-based coregistration of the preoperative and postoperative MRI scans. Postoperative outcome was analyzed with regard to (1) the completeness of the resection of the cortical abnormality and (2) the completeness of the resection of the subcortical abnormality. Complete resection of the cortical abnormality led to postoperative seizure freedom (Engel class Ia) in 34 of 37 patients (92%), whereas incomplete cortical resection achieved this in only one of 13 patients (8%, p < 0.001). Among the patients with complete cortical resection, 36 had FCDs with a subcortical hyperintensity according to MRI. In this group, complete resection of the subcortical abnormality did not result in a better postoperative outcome than incomplete resection (90% vs. 93% for Engel class Ia, n.s.). Complete resection of the MRI-documented cortical abnormality in FCD IIb is crucial for a favorable postoperative outcome. However, resection of the subcortical hyperintense zone is not essential for seizure freedom. Therefore, sparing of the subcortical white matter may reduce the surgical risk of encroaching on relevant fiber tracts. In addition, these findings give an interesting insight into the epileptogenic propensity of different parts of these lesions. Wiley Periodicals, Inc. © 2011 International League Against Epilepsy.

    To perform the first randomized controlled trial to compare laparoscopic and open liver resection. Laparoscopic liver resection is increasingly used for the surgical treatment of liver tumors. However, high-level evidence to conclude that laparoscopic liver resection is superior to open liver resection is lacking. Explanatory, assessor-blinded, single center, randomized superiority trial recruiting patients from Oslo University Hospital, Oslo, Norway from February 2012 to January 2016. A total of 280 patients with resectable liver metastases from colorectal cancer were randomly assigned to undergo laparoscopic (n = 133) or open (n = 147) parenchyma-sparing liver resection. The primary outcome was postoperative complications within 30 days (Accordion grade 2 or higher). Secondary outcomes included cost-effectiveness, postoperative hospital stay, blood loss, operation time, and resection margins. The postoperative complication rate was 19% in the laparoscopic-surgery group and 31% in the open-surgery group (12 percentage points difference [95% confidence interval 1.67-21.8; P = 0.021]). The postoperative hospital stay was shorter for laparoscopic surgery (53 vs 96 hours, P < 0.001), whereas there were no differences in blood loss, operation time, and resection margins. Mortality at 90 days did not differ significantly from the laparoscopic group (0 patients) to the open group (1 patient). In a 4-month perspective, the costs were equal, whereas patients in the laparoscopic-surgery group gained 0.011 quality-adjusted life years compared to patients in the open-surgery group (P = 0.001). In patients undergoing parenchyma-sparing liver resection for colorectal metastases, laparoscopic surgery was associated with significantly less postoperative complications compared to open surgery. Laparoscopic resection was cost-effective compared to open resection with a 67% probability. The rate of free resection margins was the same in both groups. Our results support the continued

    As a rule, postoperative imaging is carried out after spinal interventions to document the exact position of the implant material. Imaging is absolutely necessary when new clinical symptoms occur postoperatively. In this case a rebleeding or an incorrect implant position abutting a root or the spinal cord must be proven. In addition to these immediately occurring postoperative clinical symptoms, there are a number of complications that can occur several days, weeks or even months later. These include the failed back surgery syndrome, implant loosening or breakage of the material and relapse of a disc herniation and spondylodiscitis. In addition to knowledge of the original clinical symptoms, it is also important to know the operation details, such as the access route and the material used. In almost all postoperative cases, imaging with contrast medium administration and corresponding correction of artefacts by the implant material, such as the dual energy technique, correction algorithms and the use of special magnetic resonance (MR) sequences are necessary. In order to correctly assess the postoperative imaging, knowledge of the surgical procedure and the previous clinical symptoms are mandatory besides special computed tomography (CT) techniques and MR sequences.

    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

    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.

    Epilepsy surgery is a potentially curative treatment option for pharmacoresistent patients. If non-invasive methods alone do not allow to delineate the epileptogenic brain areas the surgical candidates undergo long-term monitoring with intracranial EEG. Visual EEG analysis is then used to identify the seizure onset zone for targeted resection as a standard procedure. Despite of its great potential to assess the epileptogenicty of brain tissue, quantitative EEG analysis has not yet found its way into routine clinical practice. To demonstrate that quantitative EEG may yield clinically highly relevant information we retrospectively investigated how post-operative seizure control is associated with four selected EEG measures evaluated in the resected brain tissue and the seizure onset zone. Importantly, the exact spatial location of the intracranial electrodes was determined by coregistration of pre-operative MRI and post-implantation CT and coregistration with post-resection MRI was used to delineate the extent of tissue resection. Using data-driven thresholding, quantitative EEG results were separated into normally contributing and salient channels. In patients with favorable post-surgical seizure control a significantly larger fraction of salient channels in three of the four quantitative EEG measures was resected than in patients with unfavorable outcome in terms of seizure control (median over the whole peri-ictal recordings). The same statistics revealed no association with post-operative seizure control when EEG channels contributing to the seizure onset zone were studied. We conclude that quantitative EEG measures provide clinically relevant and objective markers of target tissue, which may be used to optimize epilepsy surgery. The finding that differentiation between favorable and unfavorable outcome was better for the fraction of salient values in the resected brain tissue than in the seizure onset zone is consistent with growing evidence that spatially

    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)

    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.

    It is essential to preserve as many of the parathyroid glands, as possible, during surgery of the thyroid gland. This is achieved by visualizing them and by minimal handling of the glands. Truncal ligation of the inferior thyroid artery is quite safe. Capsular ligation of the branches of the artery is theoretically superior but requires a greater degree of skill and experience in thyroid surgery. It also puts the recurrent laryngeal nerve at a greater risk of injury. Calcitriol or 1.25 dihydroxy vitamin D is a very useful drug in managing patients with severe post-operative hypoparathyroidism

    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.

    The purpose of the present study was to determine the response of the porcine coeliac-superior mesenteric ganglion complex (CSMG) neurons projecting to the prepyloric area of the porcine stomach to peripheral neuronal damage following partial stomach resection. To identify the sympathetic neurons innervating the studied area of stomach, the neuronal retrograde tracer Fast Blue (FB) was applied to control and partial stomach resection (RES) groups. On the 22nd day after FB injection, following laparotomy, the partial resection of the previously FB-injected stomach prepyloric area was performed in animals of RES group. On the 28th day, all animals were re-anaesthetized and euthanized. The CSMG complex was then collected and processed for double-labeling immunofluorescence. In control animals, retrograde-labelled perikarya were immunoreactive to tyrosine hydroxylase (TH), dopamine β-hydroxylase (DβH), neuropeptide Y (NPY) and galanin (GAL). Partial stomach resection decreased the numbers of FB-positive neurons immunopositive for TH and DβH. However, the strong increase of NPY and GAL expression, as well as de novo-synthesis of neuronal nitric oxide synthase (nNOS) and leu5-Enkephalin (LENK) was noted in studied neurons. Furthermore, FB-positive neurons in all pigs were surrounded by a network of cocaine- and amphetamine-regulated transcript peptide (CART)-, calcitonin gene-related peptide (CGRP)-, and substance P (SP)-, vasoactive intestinal peptide (VIP)-, LENK- and nNOS- immunoreactive nerve fibers. This may suggest neuroprotective contribution of these neurotransmitters in traumatic responses of sympathetic neurons to peripheral axonal damage. Copyright © 2015 Elsevier B.V.

    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.

    The local resection of the stomach is an ideal method for preventing postoperative symptoms. There are various procedures for performing local resection, such as the laparoscopic lesion lifting method, non-touch lesion lifting method, endoscopic full-thickness resection, and laparoscopic endoscopic cooperative surgery. After the invention and widespread use of endoscopic submucosal dissection, local resection has become outdated as a curative surgical technique for gastric cancer. Nevertheless, local resection of the stomach in the treatment of gastric cancer in now expected to make a comeback with the clinical use of sentinel node navigation surgery. However, there are many issues associated with local resection for gastric cancer, other than the normal indications. These include gastric deformation, functional impairment, ensuring a safe surgical margin, the possibility of inducing peritoneal dissemination, and the associated increase in the risk of metachronous gastric cancer. In view of these issues, there is a tendency to regard local resection as an investigative treatment, to be applied only in carefully selected cases. The ideal model for local resection of the stomach for gastric cancer would be a combination of endoscopic full-thickness resection of the stomach using an ESD device and hand sutured closure using a laparoscope or a surgical robot, for achieving both oncological safety and preserved functions.

    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.

    The authors retrospectively assessed the usefulness of postoperative radiation therapy after local resection of adenoid cystic carcinoma, with emphasis on organ-conserving treatment and the cosmetic results. Between 1985 and 1995, 32 patients underwent local resection followed by postoperative radiation therapy with curative and organ-conserving intent. None of patients received any form of chemotherapy as part of their initial treatment. Radiation therapy was carried out by techniques that were appropriate for the site and extension of each tumor. The 5-year local control, disease-free, and overall survival rates of all patients were 76%, 68%, and 86%, respectively. The 5-year local control rate and disease-free survival rate of patients with microscopically positive margins were 89% and 75%, respectively, and higher than in patients with macroscopically residual disease, but no significant difference in 5-year overall survival rate was observed. The postoperative cosmetic results in 29 patients with head and neck lesions were evaluated. No difference was documented between the cosmetic results postoperatively setting and after postoperative radiotherapy, and no significant differences in cosmetic results were observed according to radiation dose. The combination of local resection with organ-conserving intent and postoperative radiation therapy provided good cosmetic results in patients with T1 or T2 lesions. Postoperative radiation therapy with smaller fractions is useful, because good local control can be achieved in patients with adenoid cystic carcinoma having microscopically positive margins without inducing any late adverse reactions. However, the number of patients was too small and the follow-up period was too short to draw any definite conclusion in regard to fraction size. A much longer follow-up study with a larger number patients will be required to accurately determine the optimal treatment intensity and duration of treatment. (K.H.)

    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.

    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.

    Full Text Available The discovery of markers to lymphatic endothelial cells and the development of novel antibodies to these markers have brought increasing attention to the lymphatics and progress in the understanding of lymphangiogenesis and cancer metastasis. In this study, we investigate the presence of lymphatic vessel invasion (LVI detected by D2-40 immunohistochemical staining in resected esophageal cancer and correlated with clinicopathologic data and patient survival. Sixty nine patients, who had a primary resection of esophageal cancer, were analyzed by univariate and multivariate logistic regression, and univariate and multivariate survival analysis. The total rate of LVI was 72% (50/69. Positive LVI was significantly correlated with lymph node metastasis (p < 0.001, tumor size (p < 0.001, histological grading (p = 0.017, tumor depth (p = 0.001, and stage (p < 0.001. Multivariate logistic analysis identified LVI (p = 0.036 as a predictor of regional lymph node metastasis. On univariate survival analysis, patients with LVI had a significantly shorter disease-free survival, cancer-specific survival and overall survival. Multivariate analysis proved that LVI diagnosed by D2-40 is an independent prognostic factor of both disease-free survival (p = 0.04 and overall survival (p = 0.032 in resected esophageal cancer. These results show that LVI assessment identifies patients at high risk for regional lymph node metastasis and that LVI is an independent prognostic factor in patients with esophageal cancer.

    Full Text Available Introduction. Three-column vertebral resections are frequently applied to correct sagittal malalignment; their effects on distant unfused levels need to be understood. Methods. 134 consecutive adult PSO patients were included (29 thoracic, 105 lumbar. Radiographic analysis included pre- and postoperative regional curvatures and pelvic parameters, with paired independent t-tests to evaluate changes. Results. A thoracic osteotomy with limited fusion leads to a correction of the kyphosis and to a spontaneous decrease of the unfused lumbar lordosis (−8°. When the fusion was extended, the lumbar lordosis increased (+8°. A lumbar osteotomy with limited fusion leads to a correction of the lumbar lordosis and to a spontaneous increase of the unfused thoracic kyphosis (+13°. When the fusion was extended, the thoracic kyphosis increased by 6°. Conclusion. Data from this study suggest that lumbar and thoracic resection leads to reciprocal changes in unfused segments and requires consideration beyond focal corrections.

    Purpose: To compare the pre- and postoperative MR appearance of craniopharyngiomas with respect to lesion size, tumour morphology and identification of surrounding normal structures. Material and Methods: MR images obtained prior to and following craniopharyngioma resection were evaluated retrospectively in 10 patients. Tumour signal charcteristics, size and extension with particular reference to the optic chiasm, the pituitary gland, the pituitary stalk and the third ventricle were evaluated. Results: Following surgery, tumour volume was reduced in all patients. In 6 patients there was further tumour volume reduction between the first and second postoperative images. Two of these patients received radiation therapy between the 2 postoperative studies, while 4 had no adjuvant treatment to the surgical intervention. There was improved visualization of the optic chiasm, in 3, the pituitary stalk in one, and the third ventricle in 9 of the 10 patients. The pituitary gland was identified preoperatively only in one patient, postoperatively only in another, pre- and postoperatively in 5, and neither pre- nor postoperatively in 3 patients. In 3 patients MR imaging 0-7 days postoperatively identified tumour remnants not seen at the end of the surgical procedure. The signal intensities of solid and cystic tumour components were stable from pre- to the first postoperative MR images. Optic tract increased signal prior to surgery was gone 28 days postoperatively in one patient, but persisted on the left side for 197 days after surgery in another. Conclusion: Postoperative MR imaging of craniopharyngiomas demonstrated tumour volume reduction and tumour remnants not seen at surgery. Early postoperative MR imaging of craniopharyngiomas may overestimate the size of residual tumour. Improved visualization of peritumoral structures may be achieved. (orig.).

    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.

    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.

    Eighty consecutive patients with advanced head and neck cancer were treated with combined therapy of radical surgery and post-operative radiotherapy. Indications for post-operative radiotherapy were pathological staging of the primary tumour (pT3 or pT4), poorly differentiated or undifferentiated carcinoma (G3, G4), tumour thickness, tumour invasion in the surrounding tissues with slender tumour strands and solitary tumour cells, perineural spread, lymphangio-invasive tumour growth, multiple positive neck nodes or extranodal spread, and microscopical irradicality of the surgical margins. The contribution for prognosis of these indications for post-operative radiotherapy were retrospectively calculated in univariate and multivariate analysis. Of all investigated parameters, the mode of tumour invasion and lymphangio-invasive growth were independent prognostic factors. If these unfavourable prognostic signs are present, post-operative radiotherapy has to be intensified to at least curative doses of 66 Gy or more to areas at risk. (author).

    Between 1985 and 1999, 43 patients with locally-advanced, resectable oropharyngeal cancer were treated with combined surgery and post-operative radiation therapy (RT) at Oregon Health and Science University. Five patients (12 per cent) had Stage III disease and 38 patients (88 per cent) had Stage IV disease. All patients had gross total resections of the primary tumour. Thirty-seven patients had neck dissections for regional disease. RT consisted of a mean tumour-bed dose of 63.0 Gy delivered in 1.8-2.0 Gy fractions over a mean of 49 days. At three- and five-years, the actuarial local control was 96 per cent and the actuarial local/regional control was 80 per cent. The three- and five-year actuarial rates of distant metastases were 41 per cent and 46 per cent, respectively. The actuarial overall survival at three- and five-years was 41 per cent and 34 per cent, respectively. The actuarial rates of progression-free survival were 49 per cent at three-years and 45 per cent at five years. Combined surgery and post-operative RT for advanced-stage oropharyngeal cancer results in excellent local/regional control. This particular group of patients experienced a high-rate of developing distant metastases.

    Purpose: With the conventional approach of surgery and postoperative radiotherapy for patients with Masaoka Stage III thymoma, progress has been slow for an improvement in the long-term survival rate over the past 20 years. The objective of this study was to evaluate the pattern of failure and survival after surgery and postoperative radiotherapy in Stage III thymoma and search for a new direction for better therapy outcome. Methods and Materials: Between 1975 and 1993, 111 patients with thymoma were treated at Massachusetts General Hospital. Of these, 32 patients were determined to have Masaoka Stage III thymoma. The initial treatment included surgery for clinically resectable disease in 25 patients and preoperative therapy for unresectable disease in 7 patients. Surgical procedure consisted of thymectomy plus resection of involved tissues. For postoperative radiotherapy (n = 23), radiation dose consisted of 45-50 Gy for close resection margins, 54 Gy for microscopically positive resection margins, and 60 Gy for grossly positive margins administered in 1.8 to 2.0 Gy of daily dose fractions, 5 fractions a week, over a period of 5 to 6.6 weeks. In preoperative radiotherapy, a dose of 40 Gy was administered in 2.0 Gy of daily dose fractions, 5 days a week. For patients with large tumor requiring more than 30% of total lung volume included in the target volume (n = 3), a preoperative radiation dose of 30 Gy was administered and an additional dose of 24-30 Gy was given to the tumor bed region after surgery for positive resection margins. Results: Patients with Stage III thymoma accounted for 29% (32/111 patients) of all patients. The median age was 57 years with a range from 27 to 81 years; gender ratio was 10:22 for male to female. The median follow-up time was 6 years. Histologic subtypes included well-differentiated thymic carcinoma in 19 (59%), high-grade carcinoma in 6 (19%), organoid thymoma in 4 (13%), and cortical thymoma in 3 (9%) according to the Marino and

    Osteosarcoma resection is challenging due to the variable location of tumors and their proximity with surrounding tissues. It also carries a high risk of postoperative complications. To overcome the challenge in precise osteosarcoma resection, computer-aided design (CAD) was used to design patient-specific guiding templates for osteosarcoma resection on the basis of the computer tomography (CT) scan and magnetic resonance imaging (MRI) of the osteosarcoma of human patients. Then 3D printing technique was used to fabricate the guiding templates. The guiding templates were used to guide the osteosarcoma surgery, leading to more precise resection of the tumorous bone and the implantation of the bone implants, less blood loss, shorter operation time and reduced radiation exposure during the operation. Follow-up studies show that the patients recovered well to reach a mean Musculoskeletal Tumor Society score of 27.125.

    The results of postoperative radiation therapy in 12 patients with stage III thymoma treated during 1966-1986 were reviewed. Surgical therapy consisted of total resection in one, subtotal resection in seven, and biopsy only in four. Megavoltage irradiation in the dose range of 3,000-5,600 cGy was employed, with nine patients receiving a dose of at least 5,000 cGy. The local control rate was 67%. The actuarial observed and adjusted 5-year survival rates were 57% and 75%, respectively. These results indicate that postoperative radiation therapy is an effective therapeutic modality in the control of stage III thymoma

    Resection and end-to-end anastomosis of the trachea is a practical procedure for the correction of various forms of tracheal stenosis. Preplacing retention sutures facilitates manipulation of the trachea and rapid apposition of the tracheal ends. These same sutures then relieve tension on the primary suture line, assuring early epithelialization. Two dogs with tracheal stenosis were treated by use of this technique. Slight narrowing of the trachea was evident postoperatively in both dogs, but neither dyspnea nor coughing occurred during the follow-up period.

    Between 1/85 and 1/90, 14 consecutive patients were entered into a prospective study of conventional adjuvant post-operative external beam radiotherapy after complete resection for a pancreatic adeno-carcinoma. The surgical procedure was a Whipple resection in 9 patients, a distal pancrea-tectomy in 1 patient. There were 3 T[sub 1b], 8 T[sub 2] and 3 T[sub 3] tumors (UICC 1987); nodal involvement was present in 5 cases. The radiotherapy was delivered using a 4-field box technique with a 23 x MV photon beam. All patients received a total dose of 54 Gy to the tumor bed. The mean treated volume was 900 cm[sup 3]. Acute toxicities consisted mainly of weight loss (mean: 2 kg). Two patients had a grade 2 diarrhea and 2 patients a grade 2 gastritis. Late effects were minimal and only observed in 2 patients. The overall loco-regional recurrence (LR) rate was 50%. The median disease-free survival was 12 months, and the median survival was 23 months. This post-operative conventional radiotherapy treatment gives results that are comparable to the results of GITSG-adjuvant study using a combination of split-course radiotherapy and 5-fluorouracil (5-FU).

    The benefit of elective primary tumor resection for non-curable stage IV colorectal cancer (CRC) remains largely undefined. We wanted to identify risk factors for postoperative complications and short survival. Using a prospective database, we analyzed potential risk factors in 233 patients, who were electively operated for non-curable stage IV CRC between 1996 and 2002. Patients with recurrent tumors, resectable metastases, emergency operations, and non-resective surgery were excluded. Risk factors for increased postoperative morbidity and limited postoperative survival were identified by multivariate analyses. Patients with colon cancer (CC = 156) and rectal cancer (RC = 77) were comparable with regard to age, sex, comorbidity, American Society of Anesthesiologists score, carcinoembryonic antigen levels, hepatic spread, tumor grade, resection margins, 30-day mortality (CC 5.1%, RC 3.9%) and postoperative chemotherapy. pT4 tumors, carcinomatosis, and non-anatomical resections were more common in colon cancer patients, whereas enterostomies (CC 1.3%, RC 67.5%, p 50%, and comorbidity >1 organ. Prognostic factors for limited postoperative survival were hepatic tumor load >50%, pT4 tumors, lymphatic spread, R1-2 resection, and lack of chemotherapy. Palliative resection is associated with a particularly unfavorable outcome in rectal cancer patients presenting with a locally advanced tumor (pT4, expected R2 resection) or an extensive comorbidity, and in all CRC patients who show a hepatic tumor load >50%. For such patients, surgery might be contraindicated unless the tumor is immediately life-threatening.

  11. Postoperative Airway Obstruction by a Bone Fragment

    2017-01-01

    Full Text Available Postoperative airway obstructions are potentially life-threatening complications. These obstructions may be classified as functional (sagging tongue, laryngospasm, or bronchospasm, pathoanatomical (airway swelling or hematoma within the airways, or foreign body-related. Various cases of airway obstruction by foreign bodies have previously been reported, for example, by broken teeth or damaged airway instruments. Here we present the exceptional case of a postoperative airway obstruction due to a large fragment of the patient’s maxillary bone, left accidentally in situ after transoral surgical tumor resection. Concerning this type of airway obstruction, we discuss possible causes, diagnosis, and treatment options. Although it is an exceptional case after surgery, clinicians should be aware of this potentially life-threatening complication. In summary, this case demonstrates that the differential diagnosis of postoperative airway obstructions should include foreign bodies derived from surgery, including tissue and bone fragments.

    To determine (1) the short- (to hospital discharge) and long- (>6 months) term survival, (2) factors associated with short-term survival, and (3) the perioperative course for horses with resection and anastomosis of the descending colon. Multicentered case series. Horses (n=43) that had descending colon resection and anastomosis. Medical records (January 1995-June 2009) of 7 equine referral hospitals were reviewed for horses that had descending colon resection and anastomosis and were recovered from anesthesia. Retrieved data included history, results of clinical and clinicopathologic examinations, surgical findings, postsurgical treatment and complications, and short-term survival (hospital discharge). Long-term survival was defined as survival > or =6 months after hospital discharge. Of 43 horses, 36 (84%) were discharged from the hospital. Twenty-eight of 30 horses with follow-up information survived > or =6 months. No significant associations between perioperative factors and short-term survival were identified. Lesions included strangulating lipoma (n=27), postfoaling trauma (4), infarction (4), intraluminal obstruction (2), and other (6). Common postoperative complications included fever and diarrhea. During hospitalization 7 horses were euthanatized or died because of septic peritonitis (3), endotoxemia (3), and colic and ileus (1). Descending colon resection and anastomosis has a favorable prognosis for hospital discharge and survival > or =6 months. The most common cause of small colon incarceration was strangulating lipoma. Complications include postoperative fever and diarrhea but the prognosis is good after small colon resection and anastomosis.

    A borderline resectable group (APBR) has recently been defined in adenocarcinoma of the pancreas. The objective of the study is to evaluate the results in the surgical treatment after neoadjuvancy of the APBR. Between 2010 and 2014, we included patients with APBR in a neoadjuvant and surgery protocol, staged by multidetector computed tomography (MDCT). Treatment with chemotherapy was based on gemcitabine and oxaliplatin. Subsequently, MDCT was performed to rule out progression, and 5-FU infusion and concomitant radiotherapy were given. MDCT and resection were performed in absence of progression. A descriptive statistical study was performed, dividing the series into: surgery group (GR group) and progression group (PROG group). We indicated neoadjuvant treatment to 22 patients, 11 of them were operated, 9 pancreatoduodenectomies, and 2 distal pancreatectomies. Of the 11 patients, 7 required some type of vascular resection; 5 venous resections, one arterial and one both. No postoperative mortality was recorded, 7 (63%) had any complications, and 4 were reoperated. The median postoperative stay was 17 (7-75) days. The pathological study showed complete response (ypT0) in 27%, and free microscopic margins (R0) in 63%. At study clossure, all patients had died, with a median actuarial survival of 13 months (9,6-16,3). The median actuarial survival of the GR group was higher than the PROG group (25 vs. 9 months; p vascular resection in most cases. Copyright © 2017 AEC. Publicado por Elsevier España, S.L.U.

    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.

    Full Text Available Objective. Improve the effectiveness of surgical treatment in patients with bilateral destructive pulmonary tuberculosis by mini-invasive resection and collapse therapy. Materials and Methods: Retrospective analysis of 222 patients’ cards with bilateral destructive pulmonary tuberculosis who were treated in the period from 1995 to 2014 in the thoracic department of Dnepropetrovsk regional clinical therapeutic and prophylactic association "Phthisiology". Patients were divided into 2 groups: basic (111 patients who underwent mini-invasive surgery and control (111 patients, who underwent standard surgical approach. The distribution of patients in investigated groups was representative by the majority of parameters. Results and discussion. The average duration of simultaneous bilateral VATS lung resections was 1,90 ± 0,12 hour, standard thoracotomies - 2,13 ± 0,19 per hour, estimated blood loss was 234±5,20ml and 433±3,70ml respectively. The average postoperative time in-patient was 52,40±2,63 days in basic and 80,10±3,58 days in the control group. Number of postoperative complications after lung resection with VATS was significantly lower (1.6 times, as compared with standard surgical approach. Volume of blood loss less than 400 ml was 93,40±3,20% in basic and 72,60±4,80% in the control group, the amount of intraoperative complications reduced by 2.2 times. Complete clinical response (decontamination and closing of cavities have been achieved in patients of the basic group by 1.6 times more often. Conclusions: For patients with bilateral pulmonary tuberculosis to perform mini-invasive surgical approach is the best option. Mini-invasive interventions with VATS due to its good abilities to visualize tissues and anatomical structures may significantly decrease the amount of intraoperative blood and plasma loss in the first postoperative day. It leads to the stabilization of tuberculosis process in the contralateral lung, responsible for

    Enhanced recovery after surgery is a modality of perioperative management with the purpose of improving results and providing a faster recovery of patients. This kind of protocol has been applied frequently in colorectal surgery, presenting less available experience and evidence in gastric surgery. According to the RICA guidelines published in 2015, a review of the bibliography and the consensus established in a multidisciplinary meeting in Zaragoza on the 9th of October 2015, we present a protocol that contains the basic procedures of fast-track for resective gastric surgery. The measures to be applied are divided in a preoperative, perioperative and postoperative stage. This document provides recommendations concerning the appropriate information, limited fasting and administration of carbohydrate drinks 2hours before surgery, specialized anesthetic strategies, minimal invasive surgery, no routine use of drainages and tubes, mobilization and early oral tolerance during the immediate postoperative period, as well as criteria for discharge. The application of a protocol of enhanced recovery after surgery in resective gastric surgery can improve and accelerate the functional recovery of our patients, requiring an appropriate multidisciplinary coordination, the evaluation of obtained results with the application of these measures and the investigation of controversial topics about which we currently have limited evidence.

    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

    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.

    Physiotherapy is considered an important component of the perioperative period of lung resection surgery. A systematic review was conducted to assess evidence for the effectiveness of different physiotherapy interventions in patients undergoing lung cancer resection surgery. Online literature databases [Medline, the Cochrane Central Register of Controlled Trials (CENTRAL), EMBASE, SCOPUS, PEDro and CINAHL] were searched up until June 2013. Studies were included if they were randomized controlled trials, compared 2 or more perioperative physiotherapy interventions or compared one intervention with no intervention, included only patients undergoing pulmonary resection for lung cancer and assessed at least 2 or more of the following variables: functional capacity parameters, postoperative pulmonary complications or length of hospital stay. Reviews and meta-analyses were excluded. Eight studies were selected for inclusion in this review. They included a total of 599 patients. Seven of the studies were identified as having a low risk of bias. Two studies assessed preoperative interventions, 4 postoperative interventions and the remaining 2 investigated the efficacy of interventions that were started preoperatively and then continued after surgery. The substantial heterogeneity in the interventions across the studies meant that it was not possible to conduct a meta-analysis. The most important finding of this systematic review is that presurgical interventions based on moderate-intense aerobic exercise in patients undergoing lung resection for lung cancer improve functional capacity and reduce postoperative morbidity, whereas interventions performed only during the postoperative period do not seem to reduce postoperative pulmonary complications or length of hospital stay. Nevertheless, no firm conclusions can be drawn because of the heterogeneity of the studies included. Further research into the efficacy and effectiveness of perioperative respiratory physiotherapy in

    Smoking is a risk factor for postoperative pulmonary complications (PPC) following non-small cell lung cancer (NSCLC) surgery. The optimal timing for preoperative smoking cessation has not been identified. Our study aimed to observe the impact of preoperative smoking cessation on PPC incidence and other postoperative outcomes including long-term survival. A prospective study included consecutive patients following resection for NSCLC in a regional thoracic centre over a 4-year period (2010-2014). Patients were stratified according to self-reported preoperative smoking status. The primary endpoint was PPC incidence, which was assessed from postoperative day one onwards using the Melbourne Group Scale. Secondary endpoints included short-term outcomes (hospital length of stay [LOS], intensive therapy unit [ITU] admission, 30-day hospital readmission rate) and long-term survival. Four hundred and sixty-two patients included 111 (24%) current smokers, 55 (12%) ex-smokers smoking groups prior to surgery. There was no significant difference in long-term survival found between the groups of differing smoking status (median follow-up 29.8 months, 95%CI 28.4-31.1). Current smokers have higher postoperative morbidity; this risk reduces following smoking cessation but 6 weeks does not appear to identify a time-point where differences in outcomes are noted.

  5. Uniportal VATS: A Sublimation of Micro-invasive Lung Cancer Resection

    Full Text Available Micro-invasive thoracic surgery, especially represented by video-assisted thoracic surgery (VATS, has become the mainstream of lung cancer resection. Traditional multi-portal VATS techniques, including four-port, three-port, and two-port VATS, have been widely used to perform nearly all kinds of lung cancer resections. However, how to make lung cancer resection less invasive is always the subject that all thoracic surgeons never stop pursuing. Compared with multi-portal VATS, uniportal VATS causes less postoperative pain and paresthesia because only one small incision is made and one intercoastal space is involved. In recent years, good clinical results have been obtained from uniportal VATS in lung cancer resections. In this paper, we’d like to present a brief summary about the progresses made in the application of uniportal VATS in lung cancer resection. Uniportal VATS is a sublimation of micro-invasive lung cancer resection.

    Duodenal endoscopic resection is the most difficult type of endoscopic treatment in the gastrointestinal tract (GI) and is technically challenging because of anatomical specificities. In addition to these technical difficulties, this procedure is associated with a significantly higher rate of complication than endoscopic treatment in other parts of the GI tract. Postoperative delayed perforation and bleeding are hazardous complications, and emergency surgical intervention is sometimes required. Therefore, it is urgently necessary to establish a management protocol for preventing serious complications. For instance, the prophylactic closure of large mucosal defects after endoscopic resection may reduce the risk of hazardous complications. However, the size of mucosal defects after endoscopic submucosal dissection (ESD) is relatively large compared with the size after endoscopic mucosal resection, making it impossible to achieve complete closure using only conventional clips. The over-the-scope clip and polyglycolic acid sheets with fibrin gel make it possible to close large mucosal defects after duodenal ESD. In addition to the combination of laparoscopic surgery and endoscopic resection, endoscopic full-thickness resection holds therapeutic potential for difficult duodenal lesions and may overcome the disadvantages of endoscopic resection in the near future. This review aims to summarize the complications and closure techniques of large mucosal defects and to highlight some directions for management after duodenal endoscopic treatment.

    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.

    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.

    The purpose of the study was to identify risk factors for early clinical and surgical recurrence in Crohn's disease (CD) patients who underwent intestinal resection. This was a retrospective study. Consecutive patients who underwent intestinal resection with a primary anastomosis from January 2011-December 2014 were enrolled. Gender, age at surgery, clinical phenotypes of CD, serum albumin and C-reactive protein level the day before surgery, smoking status at surgery, anastomosis technique, number of anastomoses, details of postoperative complications, the postoperative prophylactic treatment were assessed to figure out risk factors for postoperative clinical and surgical recurrence within 1 year after the initial resection by univariate and then multivariate analysis. Two hundred and thirty-seven patients were analyzed. The risk of early postoperative clinical recurrence was 2.99 times higher in patients suffered postoperative infectious complications [odds ratio (OR) 2.99; 95% CIs, 1.42-6.32; p = 0.004], while never-smoking was found to be a protective factor for early clinical recurrence (OR 0.326; 95% CIs, 0.18-0.59; p risk factor (OR 6.77; 95% CIs, 1.61-28.5; p = 0.009). Smoker at surgery was also a risk factor for early surgical recurrence (OR 5.41; 95% CIs, 1.36-21.5; p = 0.017). The presence of postoperative infectious complications was identified as a possible risk factor for early postoperative clinical recurrence after resection in CD patients.

    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.

  12. Local anesthetics for brain tumor resection: current perspectives

    2018-01-01

    This review summarizes the added value of local anesthetics in patients undergoing craniotomy for brain tumor resection, which is a procedure that is carried out frequently in neurosurgical practice. The procedure can be carried out under general anesthesia, sedation with local anesthesia or under local anesthesia only. Literature shows a large variation in the postoperative pain intensity ranging from no postoperative analgesia requirement in two-thirds of the patients up to a rate of 96% of the patients suffering from severe postoperative pain. The only identified causative factor predicting higher postoperative pain scores is infratentorial surgery. Postoperative analgesia can be achieved with multimodal pain management where local anesthesia is associated with lower postoperative pain intensity, reduction in opioid requirement and prevention of development of chronic pain. In awake craniotomy patients, sufficient local anesthesia is a cornerstone of the procedure. An awake craniotomy and brain tumor resection can be carried out completely under local anesthesia only. However, the use of sedative drugs is common to improve patient comfort during craniotomy and closure. Local anesthesia for craniotomy can be performed by directly blocking the six different nerves that provide the sensory innervation of the scalp, or by local infiltration of the surgical site and the placement of the pins of the Mayfield clamp. Direct nerve block has potential complications and pitfalls and is technically more challenging, but mostly requires lower total doses of the local anesthetics than the doses required in surgical-site infiltration. Due to a lack of comparative studies, there is no evidence showing superiority of one technique versus the other. Besides the use of other local anesthetics for analgesia, intravenous lidocaine administration has proven to be a safe and effective method in the prevention of coughing during emergence from general anesthesia and extubation, which

    To investigate the impact of HPV status in patients with locally advanced head and neck squamous cell carcinoma (HNSCC), who received surgery and cisplatin-based postoperative radiochemotherapy. For 221 patients with locally advanced squamous cell carcinoma of the hypopharynx, oropharynx or oral cavity treated at the 8 partner sites of the German Cancer Consortium, the impact of HPV DNA, p16 overexpression and p53 expression on outcome were retrospectively analysed. The primary endpoint was loco-regional tumour control; secondary endpoints were distant metastases and overall survival. In the total patient population, univariate analyses revealed a significant impact of HPV16 DNA positivity, p16 overexpression, p53 positivity and tumour site on loco-regional tumour control. Multivariate analysis stratified for tumour site showed that positive HPV 16 DNA status correlated with loco-regional tumour control in patients with oropharyngeal carcinoma (p=0.02) but not in the oral cavity carcinoma group. Multivariate evaluation of the secondary endpoints in the total population revealed a significant association of HPV16 DNA positivity with overall survival (p<0.01) but not with distant metastases. HPV16 DNA status appears to be a strong prognosticator of loco-regional tumour control after postoperative cisplatin-based radiochemotherapy of locally advanced oropharyngeal carcinoma and is now being explored in a prospective validation trial.

    Storey, Mark R.; Garden, Adam S.; Morrison, William H.; Eicher, Susan A.; Schechter, Naomi R.; Ang, K. Kian

    2001-01-01

    Purpose: This retrospective study assessed the outcome and patterns of failure for patients with malignant submandibular tumors treated with surgery and postoperative radiation. Methods and Materials: Between 1965 and 1995, 83 patients aged 11-83 years old received postoperative radiotherapy after resection of submandibular gland carcinomas. The most common radiation technique was an appositional field to the submandibular gland bed using electrons either alone or mixed with photons. Primary tumor bed doses ranged from 50 to 69 Gy (median, 60 Gy). Regional lymph nodes (ipsilateral Levels I-IV) were irradiated in 66 patients to a median dose of 50 Gy. Follow-up time ranged from 5 to 321 months (median, 82 months). Results: Actuarial locoregional control rates were 90%, 88%, and 88% at 2, 5, and 10 years, respectively. The corresponding disease-free survival rates were 76%, 60%, and 53%, because 27 of 74 patients (36%) who attained locoregional control developed distant metastases. Adenocarcinoma, high-grade histology, and treatment during the earlier years of the study were associated with worse locoregional control and disease-free survival. The median survival times for patients with and without locoregional control were 183 months and 19 months, respectively. Actuarial 2-, 5-, and 10-year survival rates were 84%, 71%, and 55%, respectively. Late complications occurred in 8 patients (osteoradionecrosis, 5 patients). Conclusions: High-risk cancers of the submandibular gland have a historic control rate of approximately 50% when treated with surgery alone. In the current series, locoregional control rates for high-risk patients with submandibular gland cancers treated with surgery and postoperative radiotherapy were excellent, with an actuarial locoregional control rate of 88% at 10 years

    1997-01-01

    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 Abstract Background Surgery after (chemoradiation (RCTX/RTX is felt to be plagued with a high incidence of wound healing complications reported to be as high as 70%. The additional use of vascularized flaps may help to decrease this high rate of complications. Therefore, we examined within a retrospective single-institutional study the peri--and postoperative complications in patients who underwent surgery for salvage, palliation or functional rehabilitation after (chemoradiation with regional and free flaps. As a second study end point the Karnofsky performance status (KPS was determined preoperatively and 3 months postoperatively to assess the impact of such extensive procedures on the overall performance status of this heavily pretreated patient population. Findings 21 patients were treated between 2005 and 2010 in a single institution (17 male, 4 female for salvage (10/21, palliation (4/21, or functional rehabilitation (7/21. Overall 23 flaps were performed of which 8 were free flaps. Major recipient site complications were observed in only 4 pts. (19% (1 postoperative haemorrhage, 1 partial flap loss, 2 fistulas and major donor site complications in 1 pt (wound dehiscence. Also 2 minor donor site complications were observed. The overall complication rate was 33%. There was no free flap loss. Assessment of pre- and postoperative KPS revealed improvement in 13 out of 21 patients (62%. A decline of KPS was noted in only one patient. Conclusions We conclude that within this (chemoradiated patient population surgical interventions for salvage, palliation or improve function can be safely performed once vascularised grafts are used.

    A case of tracheal stenosis in the cervical portion of the trachea was encountered in a 5.5-month-old St. Bernard-Rottweiler cross dog. Breathing difficulty was seen in the clinical examination and presence of an obvious narrowing between the 3rd-5th cervical tracheal rings was determined in the radiological examination. Under general anesthesia the portion with stenosis was resected and the healthy trachea ends were anastomosed using the split cartilage technique. In the postoperative period the breathing difficulty disappeared and there was no development of a new stenosis in the anastomosis region. In the late period check-up the patient was seen to lead a healthy life

    Colon cancer surveillance guidelines do not routinely include positron emission tomography (PET) imaging; however, its use after surgical resection has been increasing. We evaluated the secular patterns of PET use after surgical resection of colon cancer among elderly patients and identified factors associated with its increasing use. We used the SEER-linked Medicare database (July 2001 through December 2009) to establish a retrospective cohort of patients age ≥ 66 years who had undergone surgical resection for colon cancer. Postoperative PET use was assessed with the test for trends. Patient, tumor, and treatment characteristics were analyzed using univariable and multivariable logistic regression analyses. Of the 39,221 patients with colon cancer, 6,326 (16.1%) had undergone a PET scan within 2 years after surgery. The use rate steadily increased over time. The majority of PET scans had been performed within 2 months after surgery. Among patients who had undergone a PET scan, 3,644 (57.6%) had also undergone preoperative imaging, and 1,977 (54.3%) of these patients had undergone reimaging with PET within 2 months after surgery. Marriage, year of diagnosis, tumor stage, preoperative imaging, postoperative visit to a medical oncologist, and adjuvant chemotherapy were significantly associated with increased PET use. PET use after colon cancer resection is steadily increasing, and further study is needed to understand the clinical value and effectiveness of PET scans and the reasons for this departure from guideline-concordant care.

    To present the surgical results of, and postoperative complications after, resection of the levator aponeurosis as a treatment for aponeurotic blepharoptosis in patients with grafted corneas. Nine eyes with grafted corneas displaying aponeurotic blepharoptosis were investigated. Undercorrective resection of levator aponeurosis was performed on all nine patients. The margin reflex distance 1 (MRD1) values prior to the operation and at 7 days and 6 months after the operation were compared. The postoperative MRD1 values of patients with both poor and fair levator function were also evaluated. Differences in visual acuity and visual field before and after surgery were also assessed. The MRD1 values at 7 days and 6 months after the surgery were higher than before surgery, and there was no difference between the MRD1 values of patients with poor and fair levator function at these time points. Levator function 6 months after surgery improved compared with that before surgery. Neither visual acuity nor the visual field changed after the blepharoptosis surgery. There was no preoperative corneal problem in any patient, and postoperative corneal erosion in some patients resolved with only conservative care. In blepharoptosis patients with grafted corneas, the undercorrection of blepharoptosis by levator resection showed satisfactory surgical results regardless of levator function status (poor or fair), and did not adversely affect the survival of grafted corneas.

    Enhanced recovery after surgery (ERAS) programs can accelerate recovery and shorten the hospital stay after colorectal resections. The RAPID (remove, ambulate, postoperative analgesia, introduce diet) protocol is a simplified ERAS program that consists of a simplified, user-friendly single-page pro forma schedule. This study aimed to evaluate the impact of the RAPID protocol on patients undergoing both laparoscopic and open colorectal resections in two specialized colorectal units.

    Objectives  To describe the orbitopterional approach with extradural clinoidectomy for the resection of a tuberculum sellae meningioma, with an emphasis on the microsurgical and pathological anatomy of such lesions. Design  After completing the orbitopterional craniotomy in one piece, the optic nerve is identified extradurally, unroofed, and the clinoid process resected. The falciform ligament is divided and the optic nerve is decompressed extradurally. Opening the frontotemporal dura exposes the tumor in the subfrontal region. The tumor is followed along the ipsilateral and contralateral optic nerves, and its dural tail is cut and coagulated at the level of the tuberculum. Care is taken to preserve the optic nerve perforators during the dissection. Photographs of the region are borrowed from Dr Rhoton's laboratory to illustrate the microsurgical anatomy. Participants  The surgery was performed by the senior author assisted by Dr. Jaafar Basma, neurosurgery fourth-year resident. The video was edited by Dr. Vincent Nguyen, neurosurgery third-year resident. Outcome Measures  Outcome was assessed with the extent of resection and visual symptoms. Results  A near-total resection of the tumor was achieved. A small part of tumor significantly adherent to the optic nerve was intentionally left behind. The patient had a stable vision examination postoperatively. Conclusions  Understanding the microsurgical anatomy of the suprasellar region and the pathological anatomy of the tuberculum sellae meningioma is necessary to achieve a good resection of these tumors while preserving functionality of the optic apparatus. The orbitopterional approach with anterior clinoidectomy provides the appropriate access for such endeavor. The link to the video can be found at: https://youtu.be/WtAP8uqSW0M .

    2015-01-01

    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.

    female. Inclusion criteria differed among studies. 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. Low-quality evidence from one trial using the Short Form (SF)-36 questionnaire six weeks after surgery suggests that

    Laparoscopic liver surgery, especially when resective, requires both the skill of an expert laparoscopist and the experience of a liver surgeon. The aims of the study were to assess the feasibility of minor laparoscopic liver resection by means of a radiofrequency dissector and to evaluate the laparoscopic approach. From January 1993 to November 2002 we carried out 7 laparoscopic liver resections (3 men, 4 women), 5 of which for benign diseases and 2 for metastases from colorectal cancer. In 4 of the above resections we used an argon coagulator, while the last 3 were performed using a radiofrequency instrument. We had no perioperative or postoperative complications in this small series of patients. The mean perioperative blood loss was 120 ml (range: 80-200) and the procedure took about 90 minutes on average (range: 80-110). The mean hospital stay was 4 days and pain was adequately controlled by administering 2 ml of Toradol twice daily. We believe that the advantages of the laparoscopic technique together with the efficacy of the radiofrequency instrument in liver surgery will lead to a more widespread use of this procedure and extension of its use to include the safe execution of both minor and major resections.

    Purpose/Objective: Surgical resection offers an opportunity for long term survival for patients with cancer of the pancreas. Unfavorable pathologic prognostic factors following resection of these lesions include positive surgical margins and positive lymph nodes. The purpose of this study was to analyze the influence of IORT on survival of completely resected adenocarcinomas of the pancreas in patients with these poor pathologic features. Materials and Methods: From 1988 to 1994, 391 newly diagnosed patients with carcinoma of the pancreas were seen at Thomas Jefferson University Hospital. Pre-operative work-up identified 166 patients with clinically localized disease. These patients were evaluated by the Department of Radiation Oncology for possible treatment with IORT. These patients underwent exploratory laparotomy and 26 had a complete surgical resection (i.e. Whipple procedure or total pancreatectomy) and received IORT. Mean patient age was 66 ± 2 years (range: 43-80) with 15 male and 11 female patients. All patients had histologically proven adenocarcinoma of the pancreas. IORT was delivered to the surgical tumor bed and regional lymph nodes with a median dose of 15.0 Gy (range: 10.0-20.0 Gy). Technique, field size, and energy of the electron radiation beam varied with the clinical situation and were determined by the radiation oncologist. All 26 patients received post-operative external beam radiation therapy (EBRT) with concurrent weekly 5-FU chemotherapy. Follow-up times ranged from one to 84 months (median: 15 months). Actuarial survival rates were calculated by the Life-Table Method. Patient outcome was evaluated with respect to surgical margin and pathological lymph node status. Results: The overall actuarial 2-year survival rate was 44%. The overall median survival time (MST) was 19 months. At pathological review, five of the 26 patients (19%) were found to have positive surgical margins, four of whom also had involved lymph nodes. Thus, only one

    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.

    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

    Factors determining recurrence of nonfunctioning pituitary adenomas (NFAs) that require further therapy are unclear as are postoperative follow-up imaging guidelines. We aimed to identify predictors for secondary therapy after surgical resection of NFAs and use this knowledge to inform postoperative management. A single-centre retrospective study of surgically resected NFAs in 108 patients followed for up to 15 years. Serial tumour images were analysed for size, location and growth rate (GR) and tissue analysed for hormone cell type and proliferation indices with secondary treatment as outcome measure. Twenty-four of 66 (36%) patients harbouring a postoperative remnant required secondary treatment, all occurring within 10 years. No secondary treatment was required in any of 42 patients with complete tumour resection. Age, gender, remnant volume and tumour histology were not different between patients requiring and not requiring secondary therapy. Remnant GRs in those requiring secondary therapy were more than 10-fold higher (Prisk for secondary therapy. Tumour GR in the first three postoperative years correlated significantly (r 2 =.6, P<.01) with GR during the period of follow-up. In surgically resected NFAs further treatment is dependent on the presence of residual tumour, growth rate and location but not tumour histology. Postoperative growth rate of NFAs in the first 3 years of imaging can be used to tailor long-term follow-up to optimize use of health resources. © 2017 John Wiley & Sons Ltd.

    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.

    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.

    Full Text Available The exact incidence of common post-operative complications in children is not known. Most common one is post-operative nausea and vomiting followed by respiratory complications leading to hypoxia. Cardiac complications are less in children without associated congenital cardiac anomaly. Post-operative shivering, agitation and delirium are seen more often in children anaesthetised with newer inhalational agents like sevoflurane and desflurane. Urinary retention in the post-operative period could be influenced by anaesthetic drugs and regional blocks. The purpose of this article is to review the literature and present to the postgraduate students comprehensive information about the current understanding and practice pattern on various common complications in the post-operative period. Extensive literature was searched with key words of various complications from Pubmed, Google scholar and specific journal, namely paediatric anaesthesia. The relevant articles, review article meta-analysis and editorials were the primary source of information for this article.

    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.

  14. Intraperitoneal Gemcitabine Chemotherapy Treatment for Patients with Resected Pancreatic Cancer: Rationale and Report of Early Data

    Directory of Open Access Journals (Sweden)

    Paul H. Sugarbaker

    2011-01-01

    Full Text Available Currently, the surgical management of pancreas cancer is recognized around the world as inadequate. Despite a potentially curative R0 resection, long-term survival is rare. There is a strong rationale for the use of chemotherapy in the operating room to reduce local-regional of recurrent/progressive disease. Gemcitabine monotherapy administered by an intraperitoneal route in the operating room with hyperthermia and then for long-term treatment postoperatively has a pharmacologic basis in that the exposure of peritoneal surfaces to intraperitoneal gemcitabine is approximately 200–500 times the exposure that occurs within the plasma. A standardized treatment with intraoperative and long-term chemotherapy that is well tolerated would greatly facilitate further improvements in pancreas cancer treatment and may lead the way to an evolution of more successful treatment strategies of this dread disease. The aim of this paper is to present the early data on a protocol in progress in patients with resected pancreatic cancer.

    The visual evaluation of the degree of GBM resection based upon postoperative enhanced MRI is still difficult. It is explained by intricate complex of tumor residual fragments, blood cells, hemostatic tissues and perifocal edema that located in the postoperative area. We introduce the new software-based method for postoperative MRI data's objective estimation. Five independent specialists had examined 16 patients' MRI data (including 12 GBM and 4 patients with noninfiltrative intracerebral tumors) and tested the method's specificity and sensitivity against the enhanced residual tumor (ERT). Our software determines the 100% sensitivity and specificity against hemostatic agent Surgicel, the high recurrence rate of results while estimating the volume of ERT (0,14 ± 0,02 cm³) and low considerable time (5,21 ± 0,14 min). The software was can be used both daily practice and research of malignant glioma management.

    Andersson lesion (AL) can occur in patients with ankylosing spondylitis (AS). Surgical instrumentation and fusion is considered the principle management in symptomatic AL that fails to resolve from a conservative treatment. However, there is significant controversy over the ideal management. The purpose of this study is to introduce our experience and explore the efficacy and feasibility of transpedicular subtraction and disc resection osteotomy technique for patients with AL-complicating AS. From January 2009 to January 2013, 17 consecutive patients with Andersson lesion-complicating ankylosing spondylitis treated with transpedicular subtraction and disc resection osteotomy technique were retrospectively reviewed. All patients completed a follow-up of at least 2 years. The average surgical time was 219 min with a mean intraoperative blood loss of 876 ml. The average preoperative regional angle was 29.1°, 4.9° postoperatively, and 5.9° at the final follow-up. The global angle changed from 59.1° preoperatively to 24.7° after surgery with the sagittal vertical axis (SVA) changed from 153.7 to 41.1 mm. The mean VAS back pain scores decreased from 6.4 preoperatively to 1.1 postoperatively and the ODI score improved from 50.9 preoperatively to 16.9 at the final follow-up. Solid fusion was obtained in all patients. The transpedicular subtraction and disc resection osteotomy achieve satisfactory kyphosis correction, good fusion and favorable clinical outcomes with less blood loss and complications than other approaches, implying an alternative method in patients with Andersson lesion-complicating ankylosing spondylitis.

    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.

    To clarify the role of postoperative radiotherapy for adenoid cystic carcinoma of the tracheobronchial system (ACC), we analyzed patients treated at the National Cancer Center Hospital, Tokyo. Seven patients with ACC were treated with resective surgery and postoperative radiotherapy from 1962-1990. None of the primary lesions was completely surgically resected. Postoperative irradiation was delivered by standard fractionation at a dose range of 49.2-72 Gy. Four of seven patients lived more than 5 years, up to 21 years, without local recurrence. In contrast, three other patients who showed recurrence within 2 years died of disease before 5 years. Three of four patients who received postoperative irradiation of 60 Gy or more attained local control. One of three patients who received less than 60 Gy failed locally. A high dose of postoperative radiotherapy for patients with a positive surgical margin of ACC seems to improve local control and result in long-term survival. (author)

    Periocular hemangiomas can induce irreversible amblyopia by multiple mechanisms: visual deprivation, refractive error (astigmatism and/or anisometropia), or strabismus. There is a subset of complicated periocular hemangiomas most effectively managed by resection. The authors reviewed all patients from 1999 to 2008 with a periocular hemangioma that was either completely resected or debulked; whenever necessary, the levator apparatus was reinserted. Infants were included in the study if they had complete preoperative and postoperative ophthalmic assessments and there was more than a 6-month follow-up interval. Thirty-three children were treated with a mean operative age of 6.2 months and a mean follow-up interval of 48.2 months. The majority of hemangiomas were well-localized and caused corneal deformation with astigmatism or blepharoptosis. Intralesional or oral corticosteroid administration was attempted in almost one-half of patients. Postoperatively, the degree of astigmatism was statistically improved: from 3.0 diopters to 1.11 diopters (p correction was slightly greater postoperatively (from 2.76 diopters to 0.80 diopters). Resection performed after 3 months (14 patients) of age also resulted in improvement of astigmatism (from 3.39 diopters to 1.38 diopters). Reinsertion of the levator expansion was required in 34 percent of patients. The authors advocate early resection of a well-localized periocular hemangioma to prevent potentially irreversible amblyopia caused by either corneal deformation or blepharoptosis. The longer a complicated periocular hemangioma is observed, the greater the astigmatism and the less amenable it will be to correction following tumor removal.

    Anterior temporal lobe resection controls seizures in 50-60% of patients with intractable temporal lobe epilepsy but may impair memory function, typically verbal memory following left, and visual memory following right anterior temporal lobe resection. Functional reorganization can occur within the ipsilateral and contralateral hemispheres. We investigated the reorganization of memory function in patients with temporal lobe epilepsy before and after left or right anterior temporal lobe resection and the efficiency of postoperative memory networks. We studied 46 patients with unilateral medial temporal lobe epilepsy (25/26 left hippocampal sclerosis, 16/20 right hippocampal sclerosis) before and after anterior temporal lobe resection on a 3 T General Electric magnetic resonance imaging scanner. All subjects had neuropsychological testing and performed a functional magnetic resonance imaging memory encoding paradigm for words, pictures and faces, testing verbal and visual memory in a single scanning session, preoperatively and again 4 months after surgery. Event-related analysis revealed that patients with left temporal lobe epilepsy had greater activation in the left posterior medial temporal lobe when successfully encoding words postoperatively than preoperatively. Greater pre- than postoperative activation in the ipsilateral posterior medial temporal lobe for encoding words correlated with better verbal memory outcome after left anterior temporal lobe resection. In contrast, greater postoperative than preoperative activation in the ipsilateral posterior medial temporal lobe correlated with worse postoperative verbal memory performance. These postoperative effects were not observed for visual memory function after right anterior temporal lobe resection. Our findings provide evidence for effective preoperative reorganization of verbal memory function to the ipsilateral posterior medial temporal lobe due to the underlying disease, suggesting that it is the capacity

    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

    The role of pancreatectomy with en bloc venous resection and the prognostic impact of pathological venous invasion are still debated. The authors analyzed perioperative, survival results, and prognostic factors of pancreatectomy with en bloc portal (PV) or superior mesenteric vein (SMV) resection for borderline resectable pancreatic carcinoma, focusing on predictive factors of histological venous invasion and its prognostic role. A multicenter database of 406 patients submitted to pancreatectomy with en bloc SMV and/or PV resection for pancreatic adenocarcinoma was analyzed retrospectively. Univariate and multivariate analysis of factors related to histological venous invasion were performed using logistic regression model. Prognostic factors were analyzed with log-rank test and multivariate proportional hazard regression analysis. Complications occurred in 51.9 % of patients and postoperative death in 7.1 %. Histological invasion of the resected vein was confirmed in 56.7 % of specimens. Five-year survival was 24.4 % with median survival of 24 months. Vein invasion at preoperative computed tomography (CT), N status, number of metastatic lymph nodes, preoperative serum albumin were related to pathological venous invasion at univariate analysis, and vein invasion at CT was independently related to venous invasion at multivariate analysis. Use of preoperative biliary drain was significantly associated with postoperative complications. Multivariate proportional hazard regression analysis demonstrated a significant correlation between overall survival and histological venous invasion and administration of adjuvant therapy. This study identifies predictive factors of pathological venous invasion and prognostic factors for overall survival, including pathological venous invasion, which may help with patients' selection for different treatment protocols.

    Purpose: To analyze retrospectively the outcome of postoperative radiation therapy with or without concurrent chemotherapy for curatively resected stage II pancreatic cancer with T3 or N1 disease. Materials and Methods: Between January 1996 and December 2005, twenty-eight patients completed adjuvant radiation therapy at Ajou University Hospital. The patients had either pathologic T3 stage or N1 stage. The radiation target volume encompassed the initial tumor bed identified preoperatively, resection margin area and celiac nodal area. In the case of N1 patients, the radiation field extended to the lower margin of the L3 vertebra for covering both para-aortic lymph nodes bearing area. The median total radiation dose was 50 Gy. Ten patients received concurrent chemotherapy. Results: Thirteen patients (46%) showed loco-regional recurrences. The celiac axis nodal area was the most frequent site (4 patients). Five patients showed both loco-regional recurrence and a distant metastasis. Patients with positive lymph nodes had a relatively high probability of a distant metastasis (57.1%). Patients that had a positive resection margin showed a relatively high local failure rate (57.1%). The median disease-free survival period of all patients was 6 months and the 1- and 2-year disease free survival rates were 27.4% and 8.2%, respectively. The median overall survival period was 9 months. The 2- and 3-year overall survival rates were 31.6% and 15.8%, respectively. Conclusion: The pancreatic cancer patients with stage II had a high risk of local failure and a high risk of a distant metastasis. We suggest the concurrent use of an effective radiation-sensitizing chemotherapeutic drug and adjuvant chemotherapy after postoperative radiation therapy for the treatment of patients with stage II pancreatic cancer.

    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.

    Elastofibroma (EF) is a benign proliferation of connective tissue and is typically located at the dorsal thoracic wall. Most patients complain about pain during motion in the shoulder girdle. The aim of our study was to evaluate the outcome after surgical treatment of EF. This study provides an overview of typical clinical findings, diagnostics and pathogenesis of this rare entity. In this retrospective study we analyzed data of 12 patients (6 male, 6 female) with EF treated in our institution between 2004 and 2012. The mean follow-up was 4.7 years (range: 5 months to 7.5 years). All tumors were found to be unilateral and all patients had a negative medical history for EF. Visual analogue scale and range of motion (ROM) was documented pre- and postoperatively. In all patients indication for surgical resection was pain or uneasiness during movement. There was no statistically significant difference in ROM of the shoulder between pre- and postoperatively but all patients reported significantly less pain after surgical resection. Patients benefited from tumor resection by a significant reduction of pain levels and improvement of the motion-dependent discomfort.

    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)

    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.

    Posterior fossa syndrome (PFS) is a serious complication faced by neurosurgeons and their patients, especially in paediatric medulloblastoma patients. The uncertain aetiology of PFS, myriad of cited risk factors and therapeutic challenges make this phenomenon an elusive entity. The primary objective of this study was to identify associative factors related to the development of PFS in medulloblastoma patient post-tumour resection. This is a retrospective study based at a single institution. Patient data and all related information were collected from the hospital records, in accordance to a list of possible risk factors associated with PFS. These included pre-operative tumour volume, hydrocephalus, age, gender, extent of resection, metastasis, ventriculoperitoneal shunt insertion, post-operative meningitis and radiological changes in MRI. Additional variables included molecular and histological subtypes of each patient's medulloblastoma tumour. Statistical analysis was employed to determine evidence of each variable's significance in PFS permanence. A total of 19 patients with appropriately complete data was identified. Initial univariate analysis did not show any statistical significance. However, multivariate analysis for MRI-specific changes reported bilateral DWI restricted diffusion changes involving both right and left sides of the surgical cavity was of statistical significance for PFS permanence. The authors performed a clinical study that evaluated possible risk factors for permanent PFS in paediatric medulloblastoma patients. Analysis of collated results found that post-operative DWI restriction in bilateral regions within the surgical cavity demonstrated statistical significance as a predictor of PFS permanence-a novel finding in the current literature.

    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.

    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.

    At present, surgical treatment of comminuted radial head fractures without associated instability continues to be controversial. When anatomical reconstruction is not possible, radial head excision is performed. However, the appearance of long-term complications with this technique, along with the development of new radial head implants situates arthroplasty as a promising surgical alternative. The purpose of the present study was to compare the mid-term functional outcomes of both techniques. A retrospective study was performed between 2002 and 2011 on 25 Mason type-III fractures, 11 patients treated with primary radial head resection and 14 who received treatment of the fracture with metal prosthesis. At the end of follow-up, patients were contacted and outcomes evaluated according to: Mayo Elbow Performance Score (MEPS), the Disabilities of the Arm, Shoulder and Hand score (DASH) and strength measurement. Radiographic assessment (proximal migration of the radius, osteoarthritic changes, and signs of prosthesis loosening) was also performed. The average age of the sample was 53.7 years in the resection group, and 54.4 years in the replacement group, with a mean follow-up of 60.3 and 42 months respectively. According to the MEPS scale, there were 6 excellent cases, 3 good and 2 acceptable in the resection group, and 6 excellent cases, 3 good, 3 acceptable, and 2 poor in the prosthesis group. The mean DASH score were 13.5, and 24.8 for the resection and the replacement group respectively. We found one postoperative complication in the resection group (stiffness and valgus instability) and 6 in the replacement group: 3 of joint stiffness, 1 case of prosthesis breakage, and 2 neurological injuries. Although this is a retrospective study, the high complication rate occurring after radial head replacement in comparison with radial head resection, as well as good functional results obtained with this last technique, leads us to recommend it for comminuted radial head

    The aim of this study was to evaluate the clinical results of postoperative radiotherapy for parotid gland malignancy, and determine prognostic factors for locoregional control and survival. Between 1980 and 2002, 130 patients with parotid malignancy were registered in the database of the Department of Radiation Oncology, Seoul National University Hospital. The subjects of this analysis were the 72 of these 130 patients who underwent postoperative irradiation. There were 42 males and 30 females, with a median age of 46.5 years. The most common histological type was a mucoepidermoid carcinoma. There were 6, 23, 23 and 20 patients in Stages I, II, III and IV, respectively. The median dose to the tumor bed was 60 Gy, with a median fraction size of 1.8 Gy. The overall 5 and 10 year survival rates were 85 and 76%, respectively. The five-year locoregional control rate was 85%, which reached a plateau phase after 6 years. Sex and histological type were found to be statistically significant for overall survival from a multivariate analysis. No other factors, including age, facial nerve palsy and stage, were related to overall survival. For locoregional control, nodal involvement and positive resection margin were associated with poor local control. Histological type, tumor size, perineural invasion and type of surgery were not significant for locoregional control. A high survival rate of parotid gland malignancies, with surgery and postoperative radiotherapy, was confirmed. Sex and histological type were significant prognostic factors for overall survival. Nodal involvement and a positive resection margin were associated with poor locoregional control

    With the advances in microsurgical and monitoring techniques, spinal ependymomas are gross totally resected more frequently. The use of adjuvant radiotherapy has become questionable with gross total resection and its role for residual neoplasm need to be redefined. A retrospective analysis of a series of patients was carried out to investigate our clinical outcome and selected use of postoperative radiotherapy. Clinical materials and methods Between July 1990 and May 1995, nineteen patients [M : F = 12 : 7; age range: 21 to 71 years] with a spinal ependymoma were treated at University of Miami by the senior author. (BAG). Pre-operative MRI diagnosed the intraspinal tumor, and pathology reports demonstrated that each patient had a histologically confirmed ependymoma. At the time of diagnosis, the most common symptoms presented were pain (in 16 patients = 84.2%). The pattern of progression of clinical symptoms was directly related to the location of the tumor. Each patient had an MRI immediately after surgery, approximately 6 months post-operatively, and then annually. Results: All 19 patients underwent intradural microsurgical exploration with an attempted gross total resection (achieved in 16 patients = 79%) of the ependymoma through a posterior approach. Direct neural tissue stimulation halted further resection in 2 patients with questionable tumor margins. Radiation therapy was employed as a surgical adjunct in 3 patients (15.8%) because of possible residual tumor. All patients were followed up postoperatively for an average of 50.6 months (range 6 months to 6 years). All patients are surviving to date. Surgical resection of these tumors led to significant alleviation of pre-operative symptoms. There has been no radiographic evidence of tumor recurrence or growth in any patient to date. Conclusion: Surgical resection of spinal ependymoma leads to significant improvement of pre-operative symptom. Surgical removal alone, with an attempt to grossly resect the tumor

    During liver resection, bleeding remains the most important challenge. A reduction in blood loss and avoiding the need for a blood transfusion are important objectives for liver surgeons today. The authors compared the intra- and postoperative course of patients undergoing laparoscopic liver resections under intermittent total pedicle occlusion (IPO), hemihepatic vascular occlusion (HVO), and selective vascular occlusion (SVO). Retrospective analysis was conducted of patient data from 41 cases of laparoscopic liver resection in three groups of patients under different occlusion methods, including 15 cases of IPO, 15 cases of HVO, and 11 cases of SVO. The advantages and disadvantages of the various methods were compared, as well as blood loss, operation time, changes in postoperative liver function, and complications. There was no operative death in any of the 41 patients. Generally, there was no significant difference among the three groups in blood loss, clamping time, or operative time. After the operation, the effect on liver function for the HVO and SVO groups was significantly less severe than that for the IPO group (P<.05). The incidence of postoperative complications was mainly related to IPO and the larger amount of bleeding. Both HVO and SVO are feasible in laparoscopic hepatectomy and have the advantage of reducing liver remnant ischemia injury and modality rate over IPO. HVO is easy to do for left lateral lobe or resection of the left half of the liver. SVO is suitable for right lobe resection.

    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.

    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

    Conclusion: In contrast to some surgeries for emergency conditions such as long bone fracture or acute abdomen, the perioperative complications in the elderly receiving elective liver resection surgery did not differ markedly from those of younger patients. However, elderly patients would benefit even more if comprehensive postoperative care or newly improved therapies can be provided to lessen the incidence of perioperative respiratory complications.

    Gastric surgery may be performed for the treatment of a variety of benign and malignant diseases of the upper gastrointestinal tract, including peptic ulcers and gastric carcinoma. Radiographic studies with water-soluble contrast agents often are obtained to rule out leaks, obstruction, or other acute complications during the early postoperative period. Barium studies may also be obtained to evaluate for anastomotic strictures or ulcers, bile reflux gastritis, recurrent tumor, or other chronic complications during the late postoperative period. Cross-sectional imaging studies such as CT are also helpful for detecting abscesses or other postoperative collections, recurrent or metastatic tumor, or less common complications such as afferent loop syndrome or gastrojejunal intussusception. It is important for radiologists to be familiar not only with the radiographic findings associated with these various abnormalities but also with the normal appearances of the postoperative stomach on radiographic examinations, so that such appearances are not mistaken for pseudoleaks or other postoperative complications. The purpose of this article is to describe the normal postsurgical anatomy after the most commonly performed operations (including partial gastrectomy, esophagogastrectomy and gastric pull-through, and total gastrectomy and esophagojejunostomy) and to review the acute and chronic complications, normal postoperative findings, and major abnormalities detected on radiographic examinations in these patients.

    During the past 20 years, laparoscopy has revolutionized colorectal surgery. With proven benefits in patient outcomes and healthcare utilization, laparoscopic colorectal surgery has steadily increased in use. Robotic surgery, a new addition to colorectal surgery, has been suggested to facilitate and overcome limitations of laparoscopic surgery. Our objective was to compare the outcomes of robot-assisted laparoscopic resection (RALR) to laparoscopic resections (LAP) in colorectal surgery. A national inpatient database was evaluated for colorectal resections performed over a 30-month period. Cases were divided into traditional LAP and RALR resection groups. Cost of robot acquisition and servicing were not measured. Main outcome measures were hospital length of stay (LOS), operative time, complications, and costs between groups. A total of 17,265 LAP and 744 RARL procedures were identified. The RALR cases had significantly higher total cost ($5,272 increase, p < 0.001) and direct cost ($4,432 increase, p < 0.001), significantly longer operating time (39 min, p < 0.001), and were more likely to develop postoperative bleeding (odds ratio 1.6; p = 0.014) than traditional laparoscopic patients. LOS, complications, and discharge disposition were comparable. Similar findings were noted for both laparoscopic colonic and rectal surgery. RALR had significantly higher costs and operative time than traditional LAP without a measurable benefit.

    2000-06-01

    The indications for low anterior resection are based mainly on tumor location, penetration depth, histology, macroscopic appearance, etc. Patients with tumors located 2 cm above the puborectal muscle by digital examination can undergo low anterior resection. Distal surgical margins should be at least 1 cm from the tumor in cases of differentiated cancer and localized tumors of stage T2 or less and more than 2 cm in poorly differentiated cancer and tumors of stage T3 or greater with total mesorectal excision (TME). Longer distal surgical margins should be provided in patients with unlocalized tumors and extensive node metastasis. The final decision on whether low anterior resection is appropriate should be made after mesorectal preparation down to the levator muscles with adequate surgical margins. Low anterior resection is contraindicated in patients with poor anorectal function and high age. A rectal stump 1 to 2 cm from the dentate line should be maintained for better postoperative anorectal function if radical excision can still be performed.

    Full Text Available Respiratory deficits are common following curative intent lung cancer surgery and may reduce the patient's ability to be physically active. We evaluated the influence of surgery on pulmonary function, respiratory muscle strength and physical performance after lung resection. Pulmonary function, respiratory muscle strength (maximal inspiratory/expiratory pressure and 6-min walk test (6MWT were assessed pre-operatively, 2 weeks post-operatively and 6 months post-operatively in 80 patients (age 68±9 years. Video-assisted thoracoscopic surgery was performed in 58% of cases. Two weeks post-operatively, we found a significant decline in pulmonary function (forced vital capacity −0.6±0.6 L and forced expiratory volume in 1 s −0.43±0.4 L; both p<0.0001, 6MWT (−37.6±74.8 m; p<0.0001 and oxygenation (−2.9±4.7 units; p<0.001, while maximal inspiratory and maximal expiratory pressure were unaffected. At 6 months post-operatively, pulmonary function and oxygenation remained significantly decreased (p<0.001, whereas 6MWT was recovered. We conclude that lung resection has a significant short- and long-term impact on pulmonary function and oxygenation, but not on respiratory muscle strength. Future research should focus on mechanisms negatively influencing post-operative pulmonary function other than impaired respiratory muscle strength.

    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.

  14. Role of buprenorphine in acute postoperative pain

    Directory of Open Access Journals (Sweden)

    2016-07-01

    Full Text Available Nowadays acute postoperative pain persists as a high prevalence symptom. The incidence, intensity and duration of postoperative pain vary considerably from one patient to another, from one surgery to another, from one hospital to another, and even from one country to another. It is important to learn about recent developments in central sensitisation, as it plays an important role in postoperative pain. Postoperative pain is mainly nociceptive somatic, in response to surgical damage. The surgical trauma and pain cause an endocrine response that increases the secretion of cortisol, catecholamines, and other stress hormones. Tachycardia, hypertension, decreased regional blood flow, impaired immune response, hyperglycaemia, lipolysis, and negative nitrogen balance also occur. All this plays an important role in morbidity and mortality in the postoperative period. Buprenorphine is a semi-synthetic opioid derived from thebaine. It has a binding affinity for the mu, kappa and delta receptors, and has a slow dissociation from these receptors. Because of its action on the mu and kappa receptors it can be used as an analgesic, as well as for maintenance therapy in patients with a history of drug abuse. This article will describe the characteristics of acute postoperative pain, the pharmacology of buprenorphine, and its interference in the management of postoperative pain.

    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.

    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.

    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.

  19. Conservative treatment of rectal cancer with local excision and postoperative radiation therapy

    1995-01-01

    The conventional surgical treatment for patients with potentially curable transmural and/or node positive rectal cancer is a low anterior resection or abdominoperineal resection. Recently, there has been increasing interest in the use of local excision and postoperative radiation therapy as primary therapy for selected rectal cancers. The limited data suggest that the approach of local excision and postoperative radiation therapy should be limited to patients with either T 1 tumours with adverse pathological factors or T 2 tumours. Transmural tumours, which have a 24% local failure rate, are treated more effectively with standard surgery and pre- or postoperative therapy. The results of local excision and postoperative radiation therapy are encouraging, but more experience is needed to determine if this approach ultimately has similar local control and survival rates as standard surgery.

  20. Anesthetic Routines: The Anesthesiologist's Role in GI Recovery and Postoperative Ileus

    Directory of Open Access Journals (Sweden)

    John B. Leslie

    2011-01-01

    Full Text Available All patients undergoing bowel resection experience postoperative ileus, a transient cessation of bowel motility that prevents effective transit of intestinal contents or tolerance of oral intake, to varying degrees. An anesthesiologist plays a critical role, not only in the initiation of surgical anesthesia, but also with the selection and transition to effective postoperative analgesia regimens. Attempts to reduce the duration of postoperative ileus have prompted the study of various preoperative, perioperative, and postoperative regimens to facilitate gastrointestinal recovery. These include modifiable variables such as epidural anesthesia and analgesia, opioid-sparing anesthesia and analgesia, fluid restriction, colloid versus crystalloid combinations, prokinetic drugs, and use of the new peripherally acting mu-opioid receptor (PAM-OR antagonists. Review and appropriate adaptation of these multiple modifiable interventions by anesthesiologists and their surgical colleagues will facilitate implementation of a best-practice management routine for bowel resection procedures that will benefit the patient and the healthcare system.

  1. Role of exercise stress testing in preoperative evaluation of patients for lung resection.

    Science.gov (United States)

    Gilbreth, E M; Weisman, I M

    1994-06-01

    Patients with diagnosed or suspected lung cancer first require appropriate staging and proven anatomic resectability. Excellent pre-operative spirometric data (FEV1 > 2.0 L, > 60% predicted) should recommend the patient for surgery immediately without further testing. Those whose preoperative FEV1 is less than 60% predicted or whose DLCO is less than 60% predicted should be sent for quantitative lung scanning to estimate postoperative spirometry and diffusing capacity. Results showing FEV1-PPO and DLCO-PPO greater than 40% of normal suggest an acceptable surgical risk, and the patient should be referred accordingly. Those whose results are less than 40% of predicted should be exercised in some capacity to assess oxygen transport. We believe that cycle ergometry with incremental workloads and the standard monitoring is the best technique available for this (Table 1). Patients with a predicted postoperative FEV1 (or DLCO) greater than 35% of normal values and whose peak exercise VO2 is greater than 15 mL/kg/min should be offered surgery with the goal of removing the smallest volume of tissue that would be compatible with a cure. Those who do not meet these criteria, however, should not be summarily refused surgery if they are willing to accept the possibility of an earlier death or prolonged disability over the certainty of a cancer-related death in the foreseeable months ahead. Because the lung scan prediction of postoperative regional physiology and the exercise test of global oxygen transport examine different aspects of physiologic operability, we would not disagree with anyone who would advocate doing both tests in those at high risk by virtue of spirometric criteria. The logic of this combined approach is illustrated by Figure 1.

    Full Text Available Postoperative spinal wound infection is a potentially devastating complication after operative spinal procedures. Despite the utilization of perioperative prophylactic antibiotics in recent years and improvements in surgical technique and postoperative care, wound infection continues to compromise patients’ outcome after spinal surgery. In the modern era of pending health care reform with increasing financial constraints, the financial burden of post-operative spinal infections also deserves consideration. The aim of our work is to give to the reader an updated review of the latest achievements in prevention, risk factors, diagnosis, microbiology and treatment of post-operative spinal wound infections. A review of the scientific literature was carried out using electronic medical databases Pubmed, Google Scholar, Web of Science and Scopus for the years 1973-2012 to obtain access to all publications involving the incidence, risk factors, prevention, diagnosis, treatment of postoperative spinal wound infections. We initially identified 119 studies; of these 60 were selected. Despite all the measures intended to reduce the incidence of surgical site infections in spine surgery, these remain a common and potentially dangerous complication.

    The role of carcinoembryonic antigen (CEA) in pancreatic cancer remains poorly understood. Therefore, this study aimed to determine whether CEA is complementary to carbohydrate antigen 19-9 (CA19-9) in prognosis prediction after pancreatic cancer curative resection. We retrospectively reviewed records of 144 stage II curatively resected pancreatic cancer patients with preoperative and postoperative CEA and CA19-9 levels. Patients with normal preoperative CA19-9 were excluded. R0 resection margin, adjuvant treatment, and absence of angiolymphatic invasion were associated with better overall survival. There was no significant difference in median survival according to preoperative CEA levels. However, patients with normal postoperative CA19-9 (59.8 vs.16.2 months, P < 0.001) and CEA (29.4 vs. 9.3 months, P = 0.001) levels had longer overall survival than those with elevated levels. Among 76 patients with high postoperative CA19-9 levels, a better prognosis was observed in those with normal postoperative CEA levels than in those with elevated levels (19.1 vs. 9.3 months, P = 0.004). Postoperative CEA and CA19-9 levels are valuable prognostic markers in resected pancreatic cancer. Normal postoperative CEA levels indicate longer survival, even in patients with elevated postoperative CA19-9.

    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.

    The chronically dislocated paralytic hip causes postural difficulties, nursing and hygiene problems, and pain. Therapeutic options are limited. This study reviews the results of resection arthroplasty on 18 hips of 15 such patients. This procedure has many complications, including hip ankylosis, heterotopic ossification, abduction contracture and bony overgrowth. Despite this, all of the nursing goals were achieved and most patients had relief of pain. The operation is most successful in the skeletally mature patients, and it relies on soft-tissue interposition between the bony fragments and postoperative positioning to ensure optimum posture.

    Full Text Available Due to the better diagnostic feasibilities of health care facilities, the proportion of patients with small renal tumors (T1a has substantiallyincreased in recent years. In accordance with the international standards, these patients should undergo nephron-sparing surgery: neoplas-tic kidney resection. At Russian hospitals, organ-preserving treatment is not in adequate use for the technical difficulties associated withresection and for the likelihood of postoperative complications. The performed study has yielded a simple highly effective procedure ofnephrectomy in neoplasms, by using vasoselective parenchymatous sutures enhanced with polymer stripe-implants.

    A case of bladder explosion with wide rupture during transurethral resection of the prostate (TURP) is reported. Immediate cystography was performed and the patient was promptly operated; the postoperative course was uneventful. Intravesical explosion is caused by explosive gas formation and the more dangerous combination is the mixture of air and hydrogen; therefore, the introduction of air during TURP is necessary in order to produce a bladder explosion. This unusual complication of a common urological procedure is rare but serious, and should it arise always requires immediate surgical correction. Copyright 2003 S. Karger AG, Basel

    1988-01-01

    Measurement of regional cerebral blood flow (rCBF) using the i.v. 133Xe technique was carried out during resection of a right temporooccipital arteriovenous malformation (AVM) with ipsilateral middle and posterior cerebral arterial supply. Intraoperatively, a rCBF detector was in place over the right frontotemporal area, about 5 to 6 cm from the border of the AVM. Anesthesia was 0.75% isoflurane in oxygen and nitrous oxide. After dural exposure, the rCBF was 27 ml/100 g/min at a pCO2 of 29 mm Hg and a mean arterial pressure (MAP) of 90 mm Hg. The pCO2 was then elevated to 40 mm Hg, and the rCBF was increased to 55 ml/100 g/min at a MAP of 83 mm Hg. After AVM removal, the rCBF rose to 50 ml/100 g/min at a pCO2 of 27 mm Hg and a MAP of 75 mm Hg. The pCO2 was elevated to 33 mm Hg and the rCBF increased to 86 ml/100 g/min at a MAP of 97 mm Hg. During skin closure, the rCBF was 94 ml/100 g/min at a pCO2 of 26 mm Hg and a MAP of 97 mm Hg. The patient was neurologically normal postoperatively except for a mild, new visual field defect. After 2 to 3 days, the patient gradually developed lethargy, confusion, and nausea with relatively normal blood pressure. An angiogram revealed residual enlargement of the posterior cerebral artery feeding vessel. Computed tomography showed edema extending from the area of AVM resection as far as the frontal region, producing a significant midline shift anteriorly. Intraoperative rCBF monitoring revealed significant hyperperfusion after AVM resection, which was associated with signs and symptoms of the normal perfusion pressure breakthrough syndrome

    To describe a surgical technique for resection of the entire bladder neck, including the trigone and proximal urethra in dogs with invasive tumors causing life-threatening urinary tract obstruction. Clinical case reports. Dogs (n=2) with bladder tumors. Circumferential excision of the bladder neck and proximal urethra with preservation of the neurovascular pedicles was performed to remove a rhabdomyosarcoma (dog 1) and a transitional cell carcinoma (dog 2) involving the trigone and bladder neck that were causing urinary tract obstruction. Reconstruction of the bladder and proximal urethra included bilateral ureteroneocystostomy. Adjuvant chemotherapy was administered postoperatively to both dogs. Postoperatively, dogs 1 and 2 were continent after 7 and 17 days, respectively, and regained normal urinary function after resolution of a transient pollakiuria. Dog 1 had no evidence of local or regional recurrence; however, a large solitary pulmonary metastatic lesion was diagnosed 8 months later. The dog was euthanatized despite a lack of clinical signs. Dog 2 had at least 1 metastatic lesion in the abdominal wall 6 months later and was euthanatized at 580 days because of renal failure. En-bloc removal of the bladder neck and proximal urethra with preservation of the dorsal vascular and nervous pedicles, although a technically challenging procedure, can be performed without associated urinary incontinence or bladder wall necrosis. In dogs with invasive bladder tumors causing life-threatening urinary tract obstruction, resection of the bladder neck and proximal urethra should be considered as a promising surgical alternative to urinary diversion.

    To analyze the results of tracheal resection for cicatricial stenosis depending on the presence of tracheostomy. 1128 patients with tracheal cicatricial stenosis were treated for the period 1963-2015. The first group consisted of 297 patients for the period 1963-2000, the second group - 831 patients for the period 2001-2015. Most of them 684 (60.6%) were young and able-bodied (age from 21 to 50 years). In the first group 139 (46.8%) out of 297 patients had functioning tracheostomy. For the period 2001-2015 tracheostomy was made in 430 (51.7%) out of 831 patients with cicatricial stenosis. Time of cannulation varied from a few weeks to 21 years. Re-tracheostomy within various terms after decanulation was performed in 68 (15.8%) patients. Tracheal resection with anastomosis was performed in 59 and 330 in both groups respectively. At present time these operations are performed more often in view of their standard fashion in everyday practice. In the second group tracheal resection followed by anastomosis was observed in 110 (25.6%) out of 430 patients with tracheostomy that is 4.4 times more often than in previous years. In total 2 patients died after 330 circular tracheal resections within 2001-2015 including one patient with and one patient without tracheostomy. Mortality was 0.6%. Moreover, this value was slightly higher in patients operated with a functioning tracheostomy compared with those without it - 0.9 vs. 0.5% respectively. The causes of death were bleeding into tracheobronchial lumen and pulmonary embolism. The source of bleeding after tracheal resection was innominate artery. Overall incidence of postoperative complications was 2 times higher in tracheostomy patients compared with those without it - 22 (20%) vs. 26 (11.8%) cases respectively. Convalescence may be achieved in 89.8% patients after circular tracheal resection. Adverse long-term results are associated with postoperative complications. So their prevention and treatment will improve the

    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 analyze the pelvic stability after type I resection of iliac tumor. Six adult cadaveric specimens were tested. The iliac subtotal resection models were established according to Ennecking's type I resection. Markers were affixed to the key region of the pelves. Axial loading from the proximal lumbar was applied by MTS load cell in the gradient of 0-500 N in the double feet standing state. Images in front view were obtained using CCD camera. Based on Image J software, displacements of the first sacral vertebrae (S1) of the resected pelves and the intact pelves were calculated using digital marker tracing method with center-of-mass algorithm. Serious instabilities were found in the resected pelves. S1 rotational movements around the normal side femoral head of the resected pelvis were found. The average vertical displacement of S1 of the resected pelvis was (7 +/- 3) mm under vertical load of 500 newtons, which were 8.3 times compared to the intact pelvis. The average angle of S1 rotation around the normal side femoral head of the resected pelvis was (4.0 +/- 1.8) degrees, which were 12.5 times compared to the intact pelvis. Biomechanical model of type I resection of iliac tumor are established. Essential pelvic reconstruction must be introduced because of the serious instability of the bone defection after tumor resection.

    Full Text Available Synchronous major vessel resection during pancreaticoduodenectomy (PD for borderline resectable pancreatic adenocarcinoma remains controversial. In the 1970s, regional pancreatectomy advocated by Fortner was associated with unacceptably high morbidity and mortality rates, with no impact on long-term survival. With the establishment of a multidisciplinary approach, improvements in preoperative staging techniques, surgical expertise, and perioperative care reduced mortality rates and improved 5-year-survival rates are now achieved following resection in high-volume centres. Perioperative morbidity and mortality following PD with portal vein resection are comparable to standard PD, with reported 5-year-survival rates of up to 17%. Segmental resection and reconstruction of the common hepatic artery/proper hepatic artery (CHA/PHA can be performed to achieve an R0 resection in selected patients with limited involvement of the CHA/PHA at the origin of the gastroduodenal artery (GDA. PD with concomitant major vessel resection for borderline resectable tumours should be performed when a margin-negative resection is anticipated at high-volume centres with expertise in complex pancreatic surgery. Where an incomplete (R1 or R2 resection is likely neoadjuvant treatment with systemic chemotherapy followed by chemoradiation as part of a clinical trial should be offered to all patients.

    Surgical treatment of extensive cervicofacial lymphatic malformations is often challenging due to a high rate of postoperative fluid re-accumulation and lesion recurrence resulting from incomplete resection. This study suggests a combined treatment of surgical resection and postoperative adjuvant OK-432 sclerotherapy via closed suction drainage. Using comparative analysis, this study aims to evaluate the efficacy of adjuvant sclerotherapy. A retrospective chart review was performed on patients who underwent surgical resection of cervicofacial lymphatic malformations between January 2009 and July 2013. Patients were divided into two groups based on whether or not adjuvant OK-432 sclerotherapy was administered via closed suction drainage after surgery. Both surgery-related and adjuvant sclerotherapy-related complications were assessed, and treatment effectiveness was measured based on the change in Cologne Disease Score (CDS) or the need for further treatment. A total of 17 patients underwent surgical resection. Nine of these patients underwent surgical resection only, while the other eight underwent surgical resection with adjuvant OK-432 sclerotherapy. The increase in total Cologne Disease Score (CDS) and change of progression parameters were significantly higher for the adjuvant sclerotherapy group compared to the surgery-only group. Additionally, there were no cases of postoperative lymphatic fluid retention among the adjuvant sclerotherapy group. The two groups exhibited similar complication rates with no statistically significant difference. Adjuvant OK-432 sclerotherapy via closed suction drainage is a safe and effective treatment modality. The combination of surgical resection and post-operative adjuvant sclerotherapy via closed suction drainage should be integrated into the treatment algorithm of extensive cervicofacial lymphatic malformation.

    Purpose: Current National Comprehensive Cancer Network guidelines recommend postoperative radiation therapy (PORT) for patients with resected non-small cell lung cancer (NSCLC) with N2 involvement. We investigated the relationship between nodal stage and local-regional recurrence (LR), distant recurrence (DR) and overall survival (OS) for patients having an R0 resection. Methods and Materials: A multi-institutional database of consecutive patients undergoing R0 resection for stage I-IIIA NSCLC from 1995 to 2008 was used. Patients receiving any radiation therapy before relapse were excluded. A total of 1241, 202, and 125 patients were identified with N0, N1, and N2 involvement, respectively; 161 patients received chemotherapy. Cumulative incidence rates were calculated for LR and DR as first sites of failure, and Kaplan-Meier estimates were made for OS. Competing risk analysis and proportional hazards models were used to examine LR, DR, and OS. Independent variables included age, sex, surgical procedure, extent of lymph node sampling, histology, lymphatic or vascular invasion, tumor size, tumor grade, chemotherapy, nodal stage, and visceral pleural invasion. Results: The median follow-up time was 28.7 months. Patients with N1 or N2 nodal stage had rates of LR similar to those of patients with N0 disease, but were at significantly increased risk for both DR (N1, hazard ratio [HR] = 1.84, 95% confidence interval [CI]: 1.30-2.59; P=.001; N2, HR = 2.32, 95% CI: 1.55-3.48; P<.001) and death (N1, HR = 1.46, 95% CI: 1.18-1.81; P<.001; N2, HR = 2.33, 95% CI: 1.78-3.04; P<.001). LR was associated with squamous histology, visceral pleural involvement, tumor size, age, wedge resection, and segmentectomy. The most frequent site of LR was the mediastinum. Conclusions: Our investigation demonstrated that nodal stage is directly associated with DR and OS but not with LR. Thus, even some patients with, N0-N1 disease are at relatively high risk of local recurrence. Prospective

    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.

  19. Perioperative glucocorticoid administration for prevention of systemic organ failure in patients undergoing esophageal resection for esophageal carcinoma

    Directory of Open Access Journals (Sweden)

    Antônio Marcos Raimondi

    Full Text Available CONTEXT AND OBJECTIVE: Preoperative glucocorticoid administration has been proposed for reducing postoperative morbidity. This is not widely used before esophageal resection because of incomplete knowledge regarding its effectiveness. The aim here was to assess the effects of preoperative glucocorticoid administration in adults undergoing esophageal resection for esophageal carcinoma. SEARCH STRATEGY: Studies were identified by searching the Cochrane Controlled Trials Register, MEDLINE, EMBASE, Cancer Lit, SCIELO and Cochrane Library, and by manual searching from relevant articles. The last search for clinical trials for this systematic review was performed in December 2004. SELECTION CRITERIA: This review included randomized studies of patients with potentially resectable carcinomas of the esophagus that compared preoperative glucocorticoid administration with placebo. DATA COLLECTION AND ANALYSIS: Data were extracted by the same reviewers, and the trial quality was assessed using Jadad scoring. Relative risk and weighted mean difference with 95% confidence limits were used to assess the significance of the difference between the treatment arms. RESULTS: Four randomized trials involving 146 patients were found. There were no differences in postoperative mortality, sepsis, anastomotic leakage, hepatic and renal failure between the glucocorticoid and placebo groups. There were fewer postoperative respiratory complications (p = 0.005 and multiple postoperative complications (p = 0.004 and lower postoperative plasma interleukin-6 levels (p = 0.00001 with preoperative glucocorticoid administration. There was a higher postoperative PaO2/FiO2 ratio (p = 0.0001 with preoperative glucocorticoid administration. CONCLUSION: Prophylactic administration of glucocorticoids is associated with decreased postoperative complications.

    2000-03-01

    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.

  1. VATS intraoperative tattooing to facilitate solitary pulmonary nodule resection

    2008-03-01

    Full Text Available Abstract Introduction Video-assisted thoracic surgery (VATS has become routine and widely accepted for the removal of solitary pulmonary nodules of unknown etiology. Thoracosopic techniques continue to evolve with better instruments, robotic applications, and increased patient acceptance and awareness. Several techniques have been described to localize peripheral pulmonary nodules, including pre-operative CT-guided tattooing with methylene blue, CT scan guided spiral/hook wire placement, and transthoracic ultrasound. As pulmonary surgeons well know, the lung and visceral pleura may appear featureless on top of a pulmonary nodule. Case description This paper presents a rapid, direct and inexpensive approach to peripheral lung lesion resection by marking the lung parenchyma on top of the nodule using direct methylene blue injection. Methods In two patients with peripherally located lung nodules (n = 3 scheduled for VATS, we used direct methylene blue injection for intraoperative localization of the pulmonary nodule. Our technique was the following: After finger palpation of the lung, a spinal 25 gauge needle was inserted through an existing port and 0.1 ml of methylene blue was used to tattoo the pleura perpendicular to the localized nodule. The methylene blue tattoo immediately marks the lung surface over the nodule. The surgeon avoids repeated finger palpation, while lining up stapler, graspers and camera, because of the visible tattoo. Our technique eliminates regrasping and repalpating the lung once again to identify a non marked lesion. Results Three lung nodules were resected in two patients. Once each lesion was palpated it was marked, and the area was resected with security of accurate localization. All lung nodules were resected in totality with normal lung parenchymal margins. Our technique added about one minute to the operative time. The two patients were discharged home on the second postoperative day, with no morbidity. Conclusion

  2. Impaired defecatory function after resection of rectal cancer

    2007-01-01

    Combination of symptoms such as frequent bowel movement, minor fecal incontinence, defecatory urgency, and evacuation difficulty are common after sphincter-preserving surgery for rectal cancer. A number of factors including loss of reservoir function of the rectum and impaired function of the internal anal sphincter are thought to be causative of symptoms. Presentation of impaired anal function before operation, anastomosis close to the anal margin, and anastomotic leakage are known to be associated with poor postoperative function. Colonic J-pouch reconstruction and coloplasty used as methods to increase the neorectal capacity and compensate the loss of reservoir function have been reported to improve postoperative defecatory function. Neoadjuvant radiotherapy and neoadjuvant chemoradiotherapy are known to enhance the severity of impaired defecatory function. In patients who have undergone intersphincteric resection for very low rectal cancer, fecal incontinence is common but is improved with the use of colonic J-pouch reconstruction. (author)

    We aim to elaborate upon a basically new animal model for esophageal resection. A total of 17 operations on 10 dogs were performed in order to develop a model in which resection of the cervical part of the esophagus involves two steps. The first step comprises omental flap transplantation from the abdomen to the cervical region by a microsurgical method, this omental flap improving the blood supply to the organ (prevascularization). The second step is segmental resection of the esophagus 14 days later. Of the five transplanted grafts, four still survived one week after the operation; for technical reasons, one flap had thrombotized. In the two long-term survival cases with esophageal resection after prevascularizastion, there were no major complications: the resections were successful, and the omental flap 'grew into' the tissue structure of the esophagus, assisting the healing of the anastomosis. Segmental resection of the cervical part of the esophagus was performed successfully via a new type of operation on dogs.

    Digital nerve injuries in the hand are common and can result in significant impairment and functional restriction. Despite this, there is relatively little literature, particularly with respect to postoperative rehabilitation. Splinting after repair, purported to protect the repaired nerve from excessive stretch is still commonly used. Recent cadaveric studies indicate postoperative rehabilitation is not necessary with resection up to 2.5mm. A randomized controlled trial was therefore undertaken to determine whether splinting after isolated 5th degree digital nerve transection is in fact necessary. Twenty-six subjects were recruited over a two-year period and randomized to either three weeks of hand-based splinting or free active motion. ANCOVA indicated no differences in sensibility at six months between the two groups. Subjects also reported their greatest functional limitations were because of hyperesthesia. Although this study is underpowered, these limited results suggest splinting may not be required postoperatively.

    To compare magnetic resonance imaging (MRI) characteristics of torn and untorn post-operative menisci. The study group consisted of 140 patients with 148 partially resected menisci who were evaluated with a repeat knee MRI examination and subsequent repeat arthroscopic knee surgery. Two musculoskeletal radiologists retrospectively assessed the following MRI characteristics of the post-operative meniscus: contour (smooth or irregular), T2 line through the meniscus (no line, intermediate signal line, intermediate-to-high signal line, and high fluid-like signal line), displaced meniscus fragment, and change in signal pattern through the meniscus compared with baseline MRI. Positive predictive values (PPV) and negative predictive values (NPV) were calculated using arthroscopy as the reference standard. All 36 post-operative menisci with no T2 line were untorn at surgery (100% NPV), whereas 46 of the 79 post-operative menisci with intermediate T2 line, 16 of the 18 post-operative menisci with intermediate-to-high T2 line, and 14 of the 15 post-operative menisci with high T2 line were torn at surgery (58.2%, 88.9%, and 93.3% PPV respectively). Additional MRI characteristics associated with torn post-operative meniscus at surgery were irregular meniscus contour (PPV 85.7%), displaced meniscus fragment (PPV 100%), and change in signal pattern through the meniscus (PPV 99.4%). Post-operative menisci with no T2 signal line were untorn at surgery. The most useful MRI characteristics for predicting torn post-operative menisci at surgery were change in signal pattern through the meniscus compared with baseline MRI, and displaced meniscus fragment followed by high T2 line through the meniscus, intermediate-to-high T2 line through the meniscus, and irregular meniscus contour.

    The authors retrospectively studied the records and Tc-99m sulfur colloid (TSC) splenic artery and vein resection for donation to HLA-compatible relatives. Of 37 patients with postoperative TSC studies, four had no postoperative splenic abnormalities. Nineteen of the abnormal TSC studies were followed with TSC studies 2 weeks to 14 months later; three showed no change, seven showed improvements,and ten became normal. One patient required splenectomy 2 days after pancreatectomy for splenic infarction; her TSC study showed no uptake. These data suggest that the spleen usually survives splenic artery and vein resection. Absent splenic TSC uptake raises the possibility of splenic infarction but usually improves

    Non-functioning pituitary adenomas (NFAs) are the most common pituitary tumors. There is significant variability in clinical practice in terms of post-operative imaging evaluation. The objective of this manuscript is to provide an exhaustive review of published articles pertaining to the post-operative imaging evaluation of NFAs. The MEDLINE database was queried for studies investigating imaging for the post-operative evaluation of pituitary adenomas. From an initial search of 5589 articles, 37 articles were evaluated in detail and included in this review. Magnetic resonance imaging (MRI) is the gold standard for post-operative monitoring of NFAs, although functional imaging modalities may improve identification of residual tumor in conjunction with MRI. The residual tumor can be distinguished from post-operative changes by experienced practitioners using high-resolution MRI in the immediate post-operative setting (within 1 week of surgery). However, continued imaging evolution in the appearance of residual tumor or resection cavity is expected up to 3 months post-operatively. Post-operative imaging appearance of the pituitary gland, optic apparatus, and pneumocephalus patterns, correlated with the clinical outcomes. Long-term, lifetime follow-up is warranted for NFA patients who underwent surgical resection.

    The aim of this study was to determine the factors associated with postoperative atrial fibrillation (AF) in patients with left atrial (LA) myxoma. Thirty-six consecutive patients with LA myxoma (10 men, mean age: 49.3 ± 15.7 years), who were operated on between March 2010 and July 2012, were included in this retrospective study. Pre-operative electrocardiograms and echocardiographic examinations of each patient were reviewed. Postoperative AF developed in 10 patients, whereas there was no evidence of paroxysmal AF after resection of the LA myxoma in the remaining 26 patients. The patients who developed AF postoperatively were significantly older than those who did not develop AF (median: 61.5 vs 46 years; p = 0.009). Among the electrocardiographic parameters, only P-wave dispersion differed significantly between postoperative AF and non-AF patients (median: 57.6 vs 39.8 ms, p = 0.004). Logistic regression analysis revealed P- wave dispersion (OR: 1.11, 95% CI: 1.003-1.224, p = 0.043) and age (OR: 1.13, 95% CI: 1.001-1.278, p = 0.048) as independent predictors of postoperative AF in our cohort of patients. P-wave dispersion is a simple and useful parameter for the prediction of postoperative AF in patients with LA myxoma.

    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.

    Purpose: To present our single-institution experience of intensity-modulated radiotherapy (IMRT) for oral cavity cancer. Methods and Materials: Between September 2000 and December 2006, 35 patients with histologically confirmed squamous cell carcinoma of the oral cavity underwent surgery followed by postoperative IMRT. The sites included were buccal mucosa in 8, oral tongue in 11, floor of the mouth in 9, gingiva in 4, hard palate in 2, and retromolar trigone in 1. Most patients had Stage III-IV disease (80%). Ten patients (29%) also received concurrent postoperative chemotherapy with IMRT. The median prescribed radiation dose was 60 Gy. Results: The median follow-up for surviving patients was 28.1 months (range, 11.9-85.1). Treatment failure occurred in 11 cases as follows: local in 4, regional in 2, and distant metastases in 5. Of the 5 patients with distant metastases, 2 presented with dermal metastases. The 2- and 3-year estimates of locoregional progression-free survival, distant metastasis-free survival, disease-free survival, and overall survival were 84% and 77%, 85% and 85%, 70% and 64%, and 74% and 74%, respectively. Acute Grade 2 or greater dermatitis, mucositis, and esophageal reactions were experienced by 54%, 66%, and 40% of the patients, respectively. Documented late complications included trismus (17%) and osteoradionecrosis (5%). Conclusion: IMRT as an adjuvant treatment after surgical resection for oral cavity tumors is feasible and effective, with promising results and acceptable toxicity

    Current standard treatment of Pleomorphic Salivary Adenoma (PSA) of the Parotid Gland is by surgical excision. The management of incomplete excision remains undecided with post-operative radiotherapy advocated by some and observation by others. 190 patients who underwent resection of PSA of the parotid gland within the West of Scotland region from 1981 to 2008 were identified and data collected. 78/190 patients had a primary incomplete excision. 25/78 received post-operative radiotherapy and 53 were observed. Recurrences occurred in 11/53 in those observed and in 1/25 of those who received radiotherapy. 21/25 complained of significant side effects from the radiotherapy. 38 surgeons performed 190 procedures, with a range of experience from 1 to28 procedures. Radiotherapy does appear to reduce recurrence with incomplete excision, however it is associated with significant side effects. We therefore feel radiotherapy should not be routinely recommended. Subspecialisation should be adopted to increase the operating surgeon's experience. Copyright © 2014 British Association of Plastic, Reconstructive and Aesthetic Surgeons. Published by Elsevier Ltd.

    Full Text Available Background. Biliary cystadenomas (BCAs are rare, benign, potentially malignant cystic lesions of the liver, accounting for less than 5% of cystic liver tumours. We report the outcome following resection of biliary cystadenoma from a single tertiary centre. Methods. Data of patients who had resection of BCA between January 1993 and July 2014 were obtained from liver surgical database. Patient demographics, clinicopathological characteristics, operative data, and postoperative outcome were analysed. Results. 29 patients had surgery for BCA. Male : female ratio was 1 : 28. Clinical presentation was abdominal pain (74%, jaundice (20%, abdominal mass (14%, and deranged liver function tests (3%. Cyst characteristics included septations (48%, wall thickening (31%, wall irregularity (38%, papillary projections (10%, and mural nodule (3%. Surgical procedures included atypical liver resection (52%, left hemihepatectomy (34%, right hemihepatectomy (10%, and left lateral segmentectomy (3%. Median length of stay was 7 (IQ 6.5–8.5 days. Two patients developed postoperative bile leak. No patients had malignancy on final histology. Median follow-up was 13 (IQ 6.5–15.7 years. One patient developed delayed biliary stricture and one died of cholangiocarcinoma 11 years later. Conclusion. Biliary cystadenomas can be resected safely with significantly low morbidity. Malignant transformation and recurrence are rare. Complete surgical resection provides a cure.

    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.

    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.

    Despite best efforts, postoperative complications such as postoperative respiratory failure may occur and prompt recognition of the process and management is required. Postoperative respiratory failure, such as postoperative pneumonia, postpneumonectomy pulmonary edema, acute respiratory distress-like syndromes, and pulmonary embolism, are associated with high morbidity and mortality. The causes of these complications are multifactorial and depend on preoperative, intraoperative, and postoperative factors, some of which are modifiable. The article identifies some of the risk factors, causes, and treatment strategies for successful management of the patient with postoperative respiratory failure. Copyright © 2015 Elsevier Inc.

    Emphysema is a well-known risk factor for developing air leak or persistent air leak after pulmonary resection. Although quantitative computed tomography (CT) and spirometry are used to diagnose emphysema, it remains controversial whether these tests are predictive of the duration of postoperative air leak. Sixty-two consecutive patients who were scheduled to undergo major lung resection for cancer were enrolled in this prospective study to define the best predictor of postoperative air leak duration. Preoperative factors analyzed included spirometric variables and area of emphysema (proportion of the low-attenuation area) that was quantified in a three-dimensional CT lung model. Chest tubes were removed the day after disappearance of the air leak, regardless of pleural drainage. Univariate and multivariate proportional hazards analyses were used to determine the influence of preoperative factors on chest tube time (air leak duration). By univariate analysis, site of resection (upper, lower), forced expiratory volume in 1 second, predicted postoperative forced expiratory volume in 1 second, and area of emphysema ( 10%) were significant predictors of air leak duration. By multivariate analysis, site of resection and area of emphysema were the best independent determinants of air leak duration. The results were similar for patients with a smoking history (n = 40), but neither forced expiratory volume in 1 second nor predicted postoperative forced expiratory volume in 1 second were predictive of air leak duration. Quantitative CT is superior to spirometry in predicting air leak duration after major lung resection for cancer. Quantitative CT may aid in the identification of patients, particularly among those with a smoking history, requiring additional preventive procedures against air leak.

    Surgical navigation relies on accurately mapping the intraoperative state of the patient to models derived from preoperative images. In image-guided neurosurgery, soft tissue deformations are common and have been shown to compromise the accuracy of guidance systems. In lieu of whole-brain intraoperative imaging, some advocate the use of intraoperatively acquired sparse data from laser-range scans, ultrasound imaging, or stereo reconstruction coupled with a computational model to drive subsurface deformations. Some authors have reported on compensating for brain sag, swelling, retraction, and the application of pharmaceuticals such as mannitol with these models. To date, strategies for modeling tissue resection have been limited. In this paper, we report our experiences with a novel digitization approach, called a conoprobe, to document tissue resection cavities and assess the impact of resection on model-based guidance systems. Specifically, the conoprobe was used to digitize the interior of the resection cavity during eight brain tumor resection surgeries and then compared against model prediction results of tumor locations. We should note that no effort was made to incorporate resection into the model but rather the objective was to determine if measurement was possible to study the impact on modeling tissue resection. In addition, the digitized resection cavity was compared with early postoperative MRI scans to determine whether these scans can further inform tissue resection. The results demonstrate benefit in model correction despite not having resection explicitly modeled. However, results also indicate the challenge that resection provides for model-correction approaches. With respect to the digitization technology, it is clear that the conoprobe provides important real-time data regarding resection and adds another dimension to our noncontact instrumentation framework for soft-tissue deformation compensation in guidance systems.

    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.

    Postoperative pancreatic fistula (POPF) with leakage of pancreatic juice is a rare, severe complication following pancreatic resection or, less commonly, splenectomy. Definitive treatment can require multidisciplinary approaches. We report a case of stenosis of the main pancreatic duct with distal tail GRADE C POPF, occurred after splenectomy for Hodgkin lymphoma, successfully treated with combined radiological-endoscopic approach.

    Root resection was performed on endodontically treated extracted human teeth exposed to pulsed Er:YAG laser radiation at energy levels between 50 -90 mJ/pulse in wet and dry fields. The lased surfaces were examined by optical and scanning electron microscopy. The smooth, clean resected root surfaces, devoid of charring (in wet fields) indicate that the Er:YAG laser can replace the mechanical drills currently employed in endodontic periapical procedures. In addition, the laser would promote hemostasis and sterilization of the surgical field, resulting in diminished postoperative discomfort.

    Summary: Putterman clamp, a muscle clamp, is commonly used in conjunctival müllerectomies. We report 3 cases of senile ptosis repaired with levator muscle resection using the Putterman clamp. The redundant levator aponeurosis was removed with electrocautery after clamping with the Putterman clamp. The levator muscle was refixed to the tarsus with three 4-0 Vicryl stitches after adjusting the height of the eyelid fissure. No intraoperative difficulties were encountered. Ecchymosis and edema were limited in the immediate postoperative period. No complications were noted during the follow-up. The benefits of using the Putterman clamp in levator muscle resection are illustrated in these cases. PMID:27482474

    Full Text Available The Heart Institute of the University of São Paulo, Medical School is a referral center for the treatment of congenital heart diseases of neonates and infants. In the recent years, the excellent surgical results obtained in our institution may be in part due to modern anesthetic care and to postoperative care based on well-structured protocols. The purpose of this article is to review unique aspects of neonate cardiovascular physiology, the impact of extracorporeal circulation on postoperative evolution, and the prescription for pharmacological support of acute cardiac dysfunction based on our cardiac unit protocols. The main causes of low cardiac output after surgical correction of heart congenital disease are reviewed, and methods of treatment and support are proposed as derived from the relevant literature and our protocols.

    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.

    Full Text Available The incidence of squamous cell carcinoma of the head and neck remains high and ranks tenth in the structure of overall cancer morbidity. Surgical radicality has remained one of the major determinants of the long-term results of treatment so far. In the period December 2014 to January 2016, our clinic performed surgical interventions as transoral laser oral cavity and oropharyngeal resections using carbon dioxide (CO2 laser in 34 patients. Tumors are most commonly located in the area of the tongue root and oropharynx in 16 (47.1 % patients, tongue (its anterior two thirds in 14 (41.2 %, and mouth floor in 4 (11.7 %. The average length of hospital stay after transoral laser resections was 10.14 days. A nasogastric tube was postoperatively placed in 6 (17.6 % patients for 8 to 17 days. According to the results of planned histological examination, surgical interventions were microscopically radical in all cases. Transoral CO2 laser resections make possible to perform rather large radical surgical interventions with a satisfactory functional and cosmetic results, without deteriorating the long-term results of treatment.

    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

    Surgical resection is a universal component of glioma therapy. Little is known about the postoperative microenvironment due to limited preclinical models. Thus, we sought to develop a glioma resection and recurrence model in syngeneic immune-competent mice to understand how surgical resection influences tumor biology and the local microenvironment. We genetically engineered cells from a murine glioma mouse model to express fluorescent and bioluminescent reporters. Established allografts were resected using image-guided microsurgery. Postoperative tumor recurrence was monitored by serial imaging, and the peritumoral microenvironment was characterized by histopathology and immunohistochemistry. Coculture techniques were used to explore how astrocyte injury influences tumor aggressiveness in vitro. Transcriptome and secretome alterations in injured astrocytes was examined by RNA-seq and Luminex. We found that image-guided resection achieved >90% reduction in tumor volume but failed to prevent both local and distant tumor recurrence. Immunostaining for glial fibrillary acidic protein and nestin showed that resection-induced injury led to temporal and spatial alterations in reactive astrocytes within the peritumoral microenvironment. In vitro, we found that astrocyte injury induced transcriptome and secretome alterations and promoted tumor proliferation, as well as migration. This study demonstrates a unique syngeneic model of glioma resection and recurrence in immune-competent mice. Furthermore, this model provided insights into the pattern of postsurgical tumor recurrence and changes in the peritumoral microenvironment, as well as the impact of injured astrocytes on glioma growth and invasion. A better understanding of the postsurgical tumor microenvironment will allow development of targeted anticancer agents that improve surgery-mediated effects on tumor biology. © The Author(s) 2016.

    Radiation-induced rectovaginal fistula (RVF) is a severe and difficult complication after pelvic malignancy radiation. This study was to retrospectively compare the outcomes of restorative resection and colostomy only in remission of anorectal symptoms. We enrolled a cohort of 26 consecutive cases who developed RVF after pelvic radiation. Two main procedures for these patients in our institution were used: one was restorative resection and pull-through coloanal anastomosis with a prophylactic colostomy, and another was a simple colostomy without resection. Thus, we divided these patients into these two groups. Anorectal symptoms including rectal pain, bleeding, tenesmus, and perineal mucous discharge were recorded and scored prior to surgery and at postoperative multiple time points. The baseline was similar among the two groups. All patients acquired good efficacy with improved symptoms at postoperative 6, 12, and 24 months, when compared to baseline. In addition, the resection group showed a better remission of tenesmus (6 months 33.3 vs 0%; 12 months 66.7 vs 16.7%) and perineal mucous discharge (6 months 88.9 vs 6.7%; 12 months 77.8 vs 15.4%; 24 months 85.7 vs 25.0%). Furthermore, three (30%) patients in the resection group successfully reversed stomas while no stoma was closed in the simple colostomy group. Both restorative resection procedure and colostomy only can improve anorectal symptoms of radiation-induced RVF, but restorative resection can completely relieve anorectal symptoms in selected cases.

    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.

    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.

    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.

    Purpose: We analyzed long-term local control and complications in patients with either pathologically confirmed or clinical World Health Organization Grade I meningiomas treated with definitive or postoperative radiotherapy (RT) at the University of Florida. Methods: Between 1984 and 2006, 146 patients were treated with definitive (n = 88) or postoperative RT after subtotal resection (n = 57) or gross total resection (n = 1). Patients were treated with conventional (n = 41), stereotactic (n = 103), or intensity-modulated RT (n = 2) to a median dose of 52.7 Gy and followed for a median of 7.3 years (range, 0.6-22.0 years) Results: The local control rates at 5 and 10 years were as follows: definitive RT, 99% and 99%; postoperative RT, 96% and 93%; and overall, 97% and 96%, respectively. The 5- and 10-year cause-specific survival rates were as follows: definitive RT 94% and 94%, postoperative RT, 100% and 96%; and overall, 96% and 95%, respectively. The 5- and 10-year overall survival rates were as follows: definitive RT, 81% and 75%; postoperative RT, 96% and 85%; and overall, 87% and 79%, respectively. Severe RT complications occurred in 6.8% of patients; severe surgery-related complications occurred in 10 (17%) of 58 patients treated surgically. Conclusions: The likelihood of cure after definitive RT or following subtotal resection is excellent. However, a small population of patients experience severe complications, even at the moderate dose used for this disease.

    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.

    The increase in liver surgery and the proportion of resections done on the margin to postoperative liver failure make preoperative calculations regarding liver volume important. Earlier studies have shown good correlation between calculations done with ImageJ and specimen weight as well as volume calculations done with more robust systems. The correlation to actual volumes of resected liver tissue has not been investigated, and this was the aim of this study. A total of 30 patients undergoing well-defined liver resections were included in this study. Volumes calculated with ImageJ were compared to volume measurements done after the retrieval of resected liver tissue. A strong correlation between calculated and measured liver volume was found with sample concordance correlation coefficient (ρc) = 0.9950. The knowledge on the nature of liver resections sets liver surgeons in a unique position to be able to accurately predict the volumes to be resected and, therefore, also the volume that will remain after surgery. This becomes increasingly important with the evolvement of methods to extend the boundaries of liver surgery. ImageJ is a reliable tool to preoperatively assess liver volume. © The Finnish Surgical Society 2015.

    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.

    Among the various controversies in the treatment strategies for patients with thymoma, the optimal mode of resection needs to be defined. To explore whether or not the mode of resection affects the prognosis/recurrence in patients with thymoma, we evaluated the treatment outcome of patients with resected thymoma. One hundred seventy-three nonmyasthenic patients with stage I or II resected thymoma were studied. Patients were divided into two groups: a thymomectomy (resection of thymoma without total thymectomy) group (n = 100) and a thymothymomectomy (resection of thymoma with total thymectomy) group (n = 73). The differences in the clinicopathological characteristics and prognosis between the two groups were examined. Myasthenia gravis developed postoperatively in three patients (3%) in the thymomectomy group and in 6 (8%) in the thymothymomectomy group. The 5- and 10-year overall survival rates in the thymomectomy group were 96.7% and 92.2%, and those in the thymothymomectomy group were 94.0% and 86.2%, respectively (P = 0.755). Two patients (2%) in the thymomectomy group and 4 (5%) in the thymothymomectomy group experienced recurrence. There was no difference in prognosis/recurrence between the two groups. Thymothymomectomy might not always be necessary for nonmyasthenic patients with stage I or II thymoma. © 2013 Wiley Periodicals, Inc.

    2008-10-21

    While up to a third of patients may experience a decline in memory following an anterior temporal lobe resection (ATL) for epilepsy, between 10 and 20% may experience a postoperative improvement in function. The aim of this study was to examine the preoperative characteristics of these patients. Logistic regression analyses were used to determine which variables influenced postoperative memory improvement following ATL on standardized memory tests in 237 patients with unilateral hippocampal sclerosis (105 right; 132 left). A total of 22% of the right ATL and 9% of the left ATL group demonstrated a significant postoperative improvement in verbal learning. A total of 9% of the right ATL and 16% of the left ATL group demonstrated a significant postoperative improvement in visual learning. In the R ATL group, postoperative improvements in verbal learning were associated with poor preoperative verbal learning, a shorter duration of epilepsy, higher scores on the visual learning task, and an older age at the time of surgery. In the L ATL group, postoperative improvements in visual learning were associated with poor preoperative visual learning, a shorter duration of epilepsy, and a higher IQ. Postoperative improvements in memory functions associated with the ipsilateral temporal lobe were not associated with demographic or epilepsy-related variables. Memory deficits normally associated with the function of the contralateral temporal lobe in patients with unilateral hippocampal sclerosis may improve postoperatively in patients with a shorter duration of epilepsy and the cognitive capacity to develop compensatory strategies.

    Post-operative hyperbilirubinaemia in patients undergoing liver resections is associated with high morbidity and mortality. Apart from different known factors responsible for the development of post-operative jaundice, little is known about the role of hepatobiliary transport systems in the pathogenesis of post-operative jaundice in humans after liver resection. Two liver tissue samples were taken from 14 patients undergoing liver resection before and after Pringle manoeuvre. Patients were retrospectively divided into two groups according to post-operative bilirubin serum levels. The two groups were analysed comparing the results of hepatobiliary transporter [Na-taurocholate cotransporter (NTCP); multidrug resistance gene/phospholipid export pump(MDR3); bile salt export pump (BSEP); canalicular bile salt export pump (MRP2)], heat shock protein 70 (HSP70) expression as well as the results of routinely taken post-operative liver chemistry tests. Patients with low post-operative bilirubin had lower levels of NTCP, MDR3 and BSEP mRNA compared to those with high bilirubin after Pringle manoeuvre. HSP70 levels were significantly higher after ischaemia-reperfusion (IR) injury in both groups resulting in 4.5-fold median increase. Baseline median mRNA expression of all four transporters prior to Pringle manoeuvre tended to be lower in the low bilirubin group whereas expression of HSP70 was higher in the low bilirubin group compared to the high bilirubin group. Higher mRNA levels of HSP70 in the low bilirubin group could indicate a possible protective effect of high HSP70 levels against IR injury. Although the exact role of hepatobiliary transport systems in the development of post-operative hyper bilirubinemia is not yet completely understood, this study provides new insights into the molecular aspects of post-operative jaundice after liver surgery. © 2011 John Wiley & Sons A/S.

    Transumbilical single-port surgery has been associated with less postoperative pain and offers better cosmetic outcomes than conventional 3-port laparoscopic surgery. This study compares the safety and efficacy of transumbilical thoracoscopy and conventional thoracoscopy for lung wedge resection. The animals (n = 16) were randomly assigned to the transumbilical thoracoscopic approach group (n = 8) or conventional thoracoscopic approach group (n = 8). Transumbilical lung resection was performed via an umbilical incision and a diaphragmatic incision. In the conventional thoracoscopic group, lung resection was completed through a thoracic incision. For both procedures, we compared the surgical outcomes, for example, operating time and operative complications; physiologic parameters, for example, respiratory rate and body temperature; inflammatory parameters, for example, white blood cell count; and pulmonary parameters, for example, arterial blood gas levels. The animals were euthanized 2 weeks after the surgery for gross and histologic evaluations. The lung wedge resection was successfully performed in all animals. There was no significant difference in the mean operating times or complications between the transumbilical and the conventional thoracoscopic approach groups. With regard to the physiologic impact of the surgeries, the transumbilical approach was associated with significant elevations in body temperature on postoperative day 1, when compared with the standard thoracoscopic approach. This study suggests that both approaches for performing lung wedge resection were comparable in efficacy and postoperative complications. © The Author(s) 2014.

    Full Text Available Objective. Reporting of a rare case of postoperative submandibular gland swelling following craniotomy. Case Report. A 33-year-old male underwent resection for a brain tumor under general anesthesia. The tumor was resected via a retrosigmoid suboccipital approach and the patient was placed in a lateral position with his face down and turned to the right. Slight swelling of the right submandibular gland was observed just after the surgery. Seven hours after surgery, edematous change around the submandibular gland worsened and he required emergent reintubation due to airway compromise. The cause of submandibular gland swelling seemed to be an obstruction of the salivary duct due to surgical positioning. Conclusion. Once submandibular swelling and edematous change around the submandibular gland occur, they can worsen and compromise the air way within several hours after operation. Adequate precaution must be taken for any predisposing skull-base surgery that requires strong cervical rotation and flexion.

    Post-traumatic kyphosis is a common potential complication of spinal trauma and correct management of this problem is becoming ever more important. Although posterior vertebra column resection has been increasingly adopted to correct severe spinal deformity, no series of reports were found on severe post-traumatic kyphosis in the thoracolumbar region. Therefore, the present cohort retrospective study is presented to evaluate the clinical and radiographic results of posterior vertebra column resection with instrument fusion performed in patients with severe post-traumatic kyphosis. From May 2004 to May 2006, 53 patients (38 male, 15 female) at an average age of 37.6 years (range, 24 to 66 years), were surgically treated for symptomatic post-traumatic thoracolumbar kyphosis with a posterior wedge closing osteotomy at our hospital. Among them, 5 consecutive adult patients with severe post-traumatic kyphosis were included in this study. Operation time, blood loss and complications were noted in each case. Radiographic documentation was made on the basis of standing anterior-posterior (AP) and lateral views and three dimensional reconstruction images of computed tomography (CT) scans were used to further identify the apex region of a sharp angular deformity. Sagittal correction was assessed in terms of effective regional deformity (ERD) for the injury level. Assessment of radiological fusion at follow-up was based on the presence of trabecular bone bridging at the osteotomy site according to Brantigan. Preoperative and postoperative clinical assessments were performed by using Oswestry disability index (ODI), back pain was rated in all patients by the visual analog scale (VAS) preoperatively, postoperatively and at the latest follow-up. The mean operating time was 265 minutes (220 - 408 minutes), with an average blood loss of 1362 ml (870 - 2570 ml). Each patient finished at least two years of follow-up. The average ERD significantly decreased from 69 degrees (58

    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.

    Purpose: The combination of pelvic radiotherapy and 5-fluorouracil-based chemotherapy is associated with an increase in acute gastrointestinal toxicity during rectal adjuvant therapy, most notably an increased incidence of diarrhea. Previous randomized, prospective studies have limited their analysis to presenting rates of severe and life-threatening diarrhea (Grade 3 or greater), and few data are available detailing the extent of mild to moderate diarrhea. To provide baseline data for future studies, we conducted a detailed analysis of diarrhea from a prior clinical trial of adjuvant therapy for rectal cancer. Methods and Materials: In a multiinstitutional clinical trial, 204 eligible patients with rectal carcinoma that either was deeply invasive (T3-T4) or involved regional lymph nodes were randomized to receive either postoperative pelvic radiotherapy alone (45 to 50.4 Gy) or pelvic radiotherapy and bolus 5-fluorouracil-based chemotherapy. Toxicity was assessed prospectively. Results: For the 99 eligible patients who received pelvic radiotherapy alone, rates of Grades 0, 1, 2, 3, and 4 diarrhea during treatment were 59, 20, 17, 4, and 0%, respectively. For the 96 eligible patients who received radiotherapy and 5-fluorouracil, the overall rates of grades 0, 1, 2, 3, and 4 diarrhea were 21, 34, 23, 20, and 2%, respectively. The increased rates of diarrhea during adjuvant rectal therapy were manifested across all toxicity levels for patients receiving chemotherapy and pelvic radiotherapy. Of primary clinical importance is the substantial increase in severe or life-threatening diarrhea (Grade 3 or more) (22 vs. 4%, p = 0.001) Additionally, increased rates of any diarrhea and also severe or life-threatening diarrhea were observed in patients who had a low anterior resection compared with those who had an abdominoperineal resection (p < 0.001 and p = 0.006, respectively). Conclusion: These results will be of value as a baseline for investigators who want to use

    Conversion disorder is a psychiatric disorder in which psychological stress causes neurologic deficits. A 28-year-old female surgical patient had uneventful general anesthesia and emergence but developed conversion disorder 1 hour postoperatively. She reported difficulty speaking, right-hand numbness and weakness, and right-leg paralysis. Neurologic examination and imaging revealed no neuronal damage, herniation, hemorrhage, or stroke. The patient mentioned failing examinations the day before surgery and discontinuing her prescribed antidepressant medication, leading us to diagnose conversion disorder, with eventual confirmation by neuroimaging and follow-up examinations.

    Purpose: Because of the trade-off between the potentially negative quality-of-life (QoL) effects and uncertain favorable survival effect of neoadjuvant chemoradiotherapy (CRT) in patients with resectable esophageal cancer, we assessed heath-related QoL (HRQoL) for up to 1 year postoperatively in these patients treated with preoperative CRT with a non-platinum-based outpatient regimen followed by esophagectomy. Methods and Materials: Patients undergoing neoadjuvant paclitaxel and carboplatin therapy concurrent with radiotherapy followed by surgery completed standardized HRQoL questionnaires before and after CRT and at regular times up to 1 year postoperatively. We analyzed differences in generic Qol core questionnaire [QLQ-C30] and condition-specific (esophageal site-specific [OES-18]) HRQoL scores over time by using a linear mixed-effects model. Results: Mean scores of most HRQoL scales deteriorated significantly during neoadjuvant CRT. The largest deterioration was observed for physical and role-functioning scales. All except two symptom scores worsened significantly. Postoperatively, most mean HRQoL scores improved until recovery to baseline level. Speed of improvement varied. Average taste score returned to baseline 3 months postoperatively, whereas it took 1 year for the average role-functioning score to restore. The emotional-functioning score showed a different pattern; it was worst at baseline and increased over time during CRT and postoperatively. Dysphagia and pain scores worsened considerably during CRT, restored to baseline 3 months postoperatively, and were even significantly better 1 year postoperatively. Conclusions: Preoperative CRT with paclitaxel and carboplatin for patients with resectable esophageal cancer had a considerable temporary negative effect on most aspects of HRQoL. Nonetheless, all HRQoL scores were restored or even improved 1 year postoperatively

    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: To evaluate local control after surgical resection and postoperative stereotactic radiosurgery (SRS) for brain metastases. Methods and Materials: A total of 49 patients (50 lesions) were enrolled and available for analysis. Eligibility criteria included histologically confirmed malignancy with 1 or 2 intraparenchymal brain metastases, age ≥18 years, and Karnofsky performance status (KPS) ≥70. A Cox proportional hazard regression model was used to test for significant associations between clinical factors and overall survival (OS). Competing risks regression models, as well as cumulative incidence functions, were fit using the method of Fine and Gray to assess the association between clinical factors and both local failure (LF; recurrence within surgical cavity or SRS target), and regional failure (RF; intracranial metastasis outside of treated volume). Results: The median follow-up was 12.0 months (range, 1.0-94.1 months). After surgical resection, 39 patients with 40 lesions were treated a median of 31 days (range, 7-56 days) later with SRS to the surgical bed to a median dose of 1800 cGy (range, 1500-2200 cGy). Of the 50 lesions, 15 (30%) demonstrated LF after surgery. The cumulative LF and RF rates were 22% and 44% at 12 months. Patients who went on to receive SRS had a significantly lower incidence of LF (P=.008). Other factors associated with improved local control include non-small cell lung cancer histology (P=.048), tumor diameter <3 cm (P=.010), and deep parenchymal tumors (P=.036). Large tumors (≥3 cm) with superficial dural/pial involvement showed the highest risk for LF (53.3% at 12 months). Large superficial lesions treated with SRS had a 54.5% LF. Infratentorial lesions were associated with a higher risk of developing RF compared to supratentorial lesions (P<.001). Conclusions: Postoperative SRS is associated with high rates of local control, especially for deep brain metastases <3 cm. Tumors ≥3 cm with superficial dural

    Background: Squamous cell carcinoma is the most frequently seen malignant tumor of the lower lip The more tissue is lost from the lip after tumor resection, the more challenging is the reconstruction. Many methods have been described, but each has its own advantages and its disadvantages. The author presents through his own clinical experience with lower lip reconstruction at tbe NCI, an evaluation of the commonly practiced techniques. Patients and Methods: Over a 3 year period from May 2002 till May 2005, 17 cases presented at the National Cancer Institute, Cairo University, with lower lip squamous cell carcinoma. The lesions involved various regions of the lower lip excluding the commissures. Following resection, the resulting defects ranged from 1/3 of lip to total lip loss. The age of the patients ranged from 28 to 67 years and they were 13 males and 4 females With regards to the reconstructive procedures used, Karapandzic technique (orbicularis oris myocutaneous flaps) was used in 7 patients, 3 of whom underwent secondary lower lip augmentation with upper lip switch flaps Primary Abbe (Lip switch) nap reconstruction was used in two patients, while 2 other patients were reconstructed with bilateral fan flaps with vermilion reconstruction by mucosal advancement in one case and tongue flap in the other The radial forearm free nap was used only in 2 cases, and direct wound closure was achieved in three cases. All patients were evaluated for early postoperative results emphasizing on flap viability and wound problems and for late results emphasizing on oral continence, microstomia, and aesthetic outcome, in addition to the usual oncological follow-up. Results: All flaps used in this study survived completely including the 2 free flaps. In the early postoperative period, minor wound breakdown occurred in all three cases reconstructed by utilizing adjacent cheek skin flaps, but all wounds healed spontaneously. The latter three cases Involved defects greater than 2

    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.

    The incidence of vulvar cancer is increasing, but surgical treatment-the current standard of care-often leads to unsatisfactory outcomes, especially in patients with node-positive disease. Preliminary results at our centre showed that locoregional spread of vulvar carcinoma occurs within tissue domains defined by stepwise embryonic and fetal development (ontogenetic cancer fields and associated lymph node regions). We propose that clinical translation of these insights into practice could improve outcomes of surgical treatment of vulvar cancer. We did a single-centre prospective trial at the University of Leipzig's Cancer Center. Eligible patients were aged 18 years or older, had ontogenetic stage 1-3b histologically proven primary carcinoma of the vulva, and had not undergone previous surgical or radiotherapy treatment for vulvar cancer or any other major perineal or pelvic disease. In view of staged morphogenesis of the vulva from the cloacal membrane endoderm at Carnegie stage 11 to adulthood, we defined the tissue domains of tumour spread according to the theory of ontogenetic cancer fields. On the basis of ontogenetic staging, patients were treated locally with partial, total, or extended vulvar field resection; regionally with therapeutic inguinopelvic lymph node dissection; and anatomical reconstruction without adjuvant radiotherapy. The primary endpoints were recurrence-free survival, disease-specific survival, and early postoperative complications. Analysis of tumour spread and early postoperative surgical complications was done by intention to treat (ie, all patients were included), whereas outcome analyses were done per protocol. This ongoing trial is registered with the German Clinical Trials Register, number DRKS00013358. Between March 1, 2009, and June 8, 2017, 97 consecutive patients were included in the study, of whom 94 were treated per protocol with vulvar field resection, therapeutic inguinopelvic lymph node dissection, and anatomical

    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.

    A cephalic aura is a common sensory aura typically seen in frontal lobe epilepsy. The generation mechanism of cephalic aura is not fully understood. It is hypothesized that to generate a cephalic aura extensive cortical areas need to be excited. We report a patient who started to have cephalic aura after right frontal lobe resection. Magnetoencephalography (MEG) showed interictal spike and ictal change during cephalic aura, both of which were distributed in the right frontal region, and the latter involved much more widespread areas than the former on MEG sensors. The peculiar seizure onset pattern may indicate that surgical modification of the epileptic network was related to the appearance of cephalic aura. We hypothesize that generation of cephalic aura may be associated with more extensive cortical involvement of epileptic activity than that of interictal activity, in at least a subset of cases.

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

    Directory of Open Access Journals (Sweden)

    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.

    OBJECTIVE: Pre- and post-operative plasma tissue inhibitor of metalloproteinases-1 (TIMP-1) levels have a prognostic impact on patients with colorectal cancer. However, the surgical trauma may play an essential role in regulation of plasma TIMP-1 levels, which in turn may influence subsequent TIMP......-1 measurements. PATIENTS AND METHODS: Consecutively, 48 patients with colon cancer (CC) and 12 patients with nonmalignant colonic disease were randomised to undergo elective laparoscopically assisted or open resection followed by fast track recovery. Plasma samples were collected just before and 1...... to preoperative levels 30 days after surgery. Patients undergoing laparoscopically assisted or open resection had similar TIMP-1 levels at each time point. CONCLUSIONS: Major surgery has considerable impact on plasma TIMP-1 levels. Intra- and post-operative changes of plasma TIMP-1 levels are independent...

    So far, opposing outcomes have been reported following neonatal apex resection in mice, questioning the validity of this injury model to investigate regenerative mechanisms. We performed a systematic evaluation, up to 180 days after surgery, of the pathophysiological events activated upon apex resection. In response to cardiac injury, we observed increased cardiomyocyte proliferation in remote and apex regions, neovascularization, and local fibrosis. In adulthood, resected hearts remain consistently shorter and display permanent fibrotic tissue deposition in the center of the resection plane, indicating limited apex regrowth. However, thickening of the left ventricle wall, explained by an upsurge in cardiomyocyte proliferation during the initial response to injury, compensated cardiomyocyte loss and supported normal systolic function. Thus, apex resection triggers both regenerative and reparative mechanisms, endorsing this injury model for studies aimed at promoting cardiomyocyte proliferation and/or downplaying fibrosis.

    Exostosis osteochondroma is usually resected with the whole condyle even part of it is not involved. This study was to report the effect of using digital template in the assistant of resection while protecting the uninvolved condyle. We used computer-aided design technique in the assistant of making preoperative plan of a patient with giant condylar osteochondroma of exogenous type, including determining the boundary between the tumor and the articular surface of condyle, and designing the virtual tumor resection plane, surgical approach, and remove-out path of the tumor. The digital osteotomy template was made by rapid prototyping technique based on the preoperative plan. Postoperative CT scan was performed and merged with the preoperative CT by the Proplan 1.3 system to evaluate the accuracy of surgical resection with the guide of digital template. The osteotomy template was attached to the lateral surface of condyle accurately, and the tumor was removed totally by the guide of the template without injuries to adjacent nerves and vessels. Postoperative CT showed that the osteochondroma was removed completely and the unaffected articular surface of condyle was preserved well. The merging of postoperative and preoperative CT by Proplan 1.3 system showed the outcome of the operation matched with the preoperative planning quite well with an error of 0.92 mm. There was no sign of recurrence after 6 months of follow-up. The application of digital template could improve the accuracy of the giant condylar tumor resection and help to preserve the uninvolved condyle. The use of digital template could reduce injuries to the nerves and vessels as well as save time for the operation.

    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.

    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.

    Purpose: Microscopically positive or close margins after surgical resection results in an approximately 21-26% local failure rate despite excellent postoperative external radiation therapy. We sought to demonstrate improved local control in head and neck cancer patients who had a resection with curative intent, and had unexpected, microscopically positive or close surgical margins. Methods and Materials: Twenty-nine patients with microscopically close or positive margins after curative surgery were given definitive, adjuvant external radiation therapy and 125 I brachytherapy. All 29 patients had squamous cell cancer and tonsil was the most common subsite within the head and neck region. After external radiation therapy and thorough discussions with the attending surgeon and pathologists, the slides, gross specimens, and appropriate radiographs were reviewed and a target volume was determined. The target volume was the region of the margin in question and varied in size based on the surgery and pathologic results. Once the target volume was identified the patient was taken back to the operating room for insertion of 125 I seeds. Activity implanted (range 2.9-21.5 millicuries) was designed to administer a cumulative lifetime dose of 120-160 Gy. Results: Twenty-nine patients were followed for a median of 26 months (range 5-86 months). Two-year actuarial local control was 92%. Conclusion: 125 I, after external radiation therapy, is an excellent method to improve local control in the subset of patients with unexpectedly unsatisfactory margins

    Early endoscopic recurrence is frequently observed in patients following resection for Crohn's disease (CD). However, factors affecting the incidence of an early postoperative endoscopic recurrence (EPER) have not been fully determined. The aim of this study was to evaluate risk factors for EPER after ileocolonic resection for CD. This was a retrospective, international multicentre study, in which 127 patients with a first ileocolonoscopy conducted between 6 and 12 months after ileocolonic resection for CD were included. Endoscopic recurrence was defined as a Rutgeerts score of ≥ i2. The following variables were investigated as potential risk factors for EPER: gender, age at surgery, location and behaviour of CD, smoking, concomitant perianal lesions, preoperative use of steroids, immunomodulators and biologics, previous resection, blood transfusion, surgical procedure (open vs laparoscopic approach), length of resected bowel, type of anastomosis (side-to-side vs end-to-end), postoperative complications, granuloma and postoperative biological therapy. Variables related to the patient, disease and surgical procedure were investigated as potential risk factors for EPER, with univariate and multivariate (logistic regression) analyses. 43/127 (34%) patients had EPER at the time of the first postoperative ileocolonoscopy. In univariate analysis, only preoperative steroid use was significantly associated with a higher rate of EPER [21/45 patients (47%) on steroids and 22/82 patients (27%) without steroids (P = 0.04)]. In multivariate analysis, only preoperative steroid use was a significant independent risk factor for EPER (odds ratio 3.28, 95% confidence interval: 1.30-8.28; P = 0.01). This study found that only preoperative steroid use was a significant risk factor for EPER after ileocolonic resection for CD. Prospective studies are necessary to evaluate precisely the impact of perioperative medications on EPER rates. Colorectal Disease © 2016 The Association

    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.

    Full Text Available In the past few years, the bipolar technique of resecting the prostate has become available worldwide, and currently alongside other minimally invasive techniques, especially different laser modalities, challenges the monopolar transurethral resection of the prostate (TURP as being the gold standard in treating benign prostatic hyperplasia (BPH. The proposed advantages of bipolar resection are improved haemostasis, better intraoperative visualisation, use of saline as an irrigant, which reduces the risk for TUR syndrome, shorter catheterisation time and reduced hospital stay. This study compares monopolar and bipolar TURP with respect to safety, efficacy and complications. MATERIALS AND METHODS This study was performed in the Department of Urology, Rajarajeswari Medical College and Hospital, Bangalore from March 2015 to March 2016 after ethics committee clearance. Fifty patients with bladder outlet obstruction due to BPH were randomised into two groups (the first managed by standard monopolar TURP and the second managed by bipolar TURP. RESULTS Resection and operative time is comparable in both groups. Volume of the irrigation fluid used was less in Bipolar group, but this difference was statistically insignificant. In Bipolar TURP, change in Serum Na levels postoperatively is less compared to monopolar group and this difference is statistically significant. Postoperative catheter duration was found same in both groups. Although postoperative hospital stay and patients requiring blood transfusion was less in bipolar group, this difference was not found significant statistically. Postoperative complication rate in bipolar group was less but it was not statistically significant. CONCLUSION Bipolar TURP has an equivalent complication profile; however, the elimination of a patient return electrode pad and toxicity from hypo-osmolar irrigation fluids may provide an extra level of patient safety. Longer followup is needed to determine if this

    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 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 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.

    Guidelines recommend measuring preoperative carcinoembryonic antigen (CEA) in patients with colon cancer. Although persistently elevated CEA after surgery has been associated with increased risk for metastatic disease, prognostic significance of elevated preoperative CEA that normalized after resection is unknown. To investigate whether patients with elevated preoperative CEA that normalizes after colon cancer resection have a higher risk of recurrence than patients with normal preoperative CEA. This retrospective cohort analysis was conducted at a comprehensive cancer center. Consecutive patients with colon cancer who underwent curative resection for stage I to III colon adenocarcinoma at the center from January 2007 to December 2014 were identified. Patients were grouped into 3 cohorts: normal preoperative CEA, elevated preoperative but normalized postoperative CEA, and elevated preoperative and postoperative CEA. Three-year recurrence-free survival (RFS) and hazard function curves over time were analyzed. A total of 1027 patients (461 [50.4%] male; median [IQR] age, 64 [53-75] years) were identified. Patients with normal preoperative CEA had 7.4% higher 3-year RFS (n = 715 [89.7%]) than the combined cohorts with elevated preoperative CEA (n = 312 [82.3%]) (P = .01) but had RFS similar to that of patients with normalized postoperative CEA (n = 142 [87.9%]) (P = .86). Patients with elevated postoperative CEA had 14.9% lower RFS (n = 57 [74.5%]) than the combined cohorts with normal postoperative CEA (n = 857 [89.4%]) (P = .001). The hazard function of recurrence for elevated postoperative CEA peaked earlier than for the other cohorts. Multivariate analyses confirmed that elevated postoperative CEA (hazard ratio [HR], 2.0; 95% CI, 1.1-3.5), but not normalized postoperative CEA (HR, 0.77; 95% CI, 0.45-1.30), was independently associated with shorter RFS. Elevated preoperative CEA that normalizes after resection is not an indicator of

    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.

    Brain regions are removed to treat lesions, but great care must be taken not to disturb or remove functional areas in the lesion and in surrounding tissue where healthy and diseased cells may be intermingled, especially for infiltrating tumors. Cortical functional areas and fiber tracts can be localized preoperatively by probabilistic anatomical tools, but mapping of functional integrity by neurophysiology is essential. Identification of the primary motor cortex seems to be more effectively performed with transcranial magnetic stimulation (TMS) than functional magnetic resonance imaging (fMRI). Language area localization requires auditory evoked potentials or TMS, as well as fMRI and diffusion tensor imaging for fiber tracts. Somatosensory cortex is most effectively mapped by somatosensory evoked potentials. Crucial eloquent areas, such as the central sulcus, primary somatomotor areas, corticospinal tract must be defined and for some areas that must be removed, potential compensations may be identified. Oncological/functional ratio must be optimized, resecting the tumor maximally but also sparingly, as far as possible, the areas that mediate indispensable functions. In some cases, a transient postoperative deficit may be inevitable. In this article, we review intraoperative exploration of motricity, language, somatosensory, visual and vestibular function, calculation, memory and components of consciousness.

  19. Strategic Considerations for Effective Sagittal Resection of the Mandible to Achieve a Slim and Attractive Jawline.

    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.

    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.

    In recent years more and more data have emerged linking the most radical resection to prolonged survival in patients harboring brain tumors. Since total tumor resection could increase postoperative morbidity, many methods have been suggested to reduce the risk of postoperative neurological deficits: awake craniotomy with the possibility of continuous patient-surgeon communication is one of the possibilities of finding out how radical a tumor resection can possibly be without causing permanent harm to the patient.In 1994 we started to perform awake craniotomy for glioma resection. In 2005 the use of intraoperative high-field magnetic resonance imaging (MRI) was included in the standard tumor therapy protocol. Here we review our experience in performing awake surgery for gliomas, gained in 219 patients.Patient selection by the operating surgeon and a neuropsychologist is of primary importance: the patient should feel as if they are part of the surgical team fighting against the tumor. The patient will undergo extensive neuropsychological testing, functional MRI, and fiber tractography in order to define the relationship between the tumor and the functionally relevant brain areas. Attention needs to be given at which particular time during surgery the intraoperative MRI is performed. Results from part of our series (without and with ioMRI scan) are presented.

    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 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.

    Pelvic exenteration (PE) offers the best chance of cure for locally advanced primary or recurrent pelvic organ malignancies invading adjacent organs. The aims of this study were to analyse results for any pelvic exenteration that includes rectal resection and the analysis of results of fecal and urinary reconstruction. From January 2000 to April 2014, 111 PE with rectal resection for any pelvic cancer were analysed retrospectively at two national tertiary referral centers. Thirty-six colorectal anastomosis were performed. Urologic reconstructions performed were 30 double barrelled wet colostomy (DBWC), 14 Bricker ileal conduit (BIC), and 2 ureterocutaneostomies. Postoperative complications occurred in 71 patients (64%). Six deaths (5.4%) occurred within 30 postoperative days. Five-year overall survival following R0 resection was 62.6%; R1: 42.7%; R2: 24.2% (P=.018). The resection margin status was associated with overall survival, local recurrence and distant recurrence. Pelvic exenterations for any cause need to be performed in referral centers and by specialized surgeons. Anastomosis after modified supralevator pelvic exenteration for ovarian cancer, is safe. DBWC can be considered a valid option for urologic reconstruction. The most important prognostic factor after pelvic exenteration for malignant pelvic tumors is the status of surgical margins.

    Geerdsen, J P; Frølund, L

    1984-11-01

    The incidence of postoperative recurrence of nontoxic goitre was evaluated in 175 patients. The average observation period was 8.8 years. Levothyroxine (Eltroxin) had been taken by 104 of these patients as long-term prophylaxis against goitre recurrence. Ten (9.5%) of the 104 had recurrence. The other 71 patients received no or only brief thyroxine medication postoperatively. In this group there were eight recurrences (11.3%). The difference was not significant, nor did the two groups differ significantly in regard to sex and age distribution, pathologic anatomy and observation time. Routine long-term administration of thyroxine after thyroid resection is not justified from the results of this study.

    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 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.

    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.

    Full Text Available Objective To summarize the curative effect of argon-helium cryoablation in resection of intracranial tumors.  Methods and Results A total of 11 patients with primary intracranial tumors, including 7 cases of glioma and 4 cases of meningioma, were enrolled in this study. The tumor was located in left frontal lobe in 4 cases, left fronto-parietal lobe in 2 cases, left temporal lobe in 2 cases and right temporo-parietal lobe in 3 cases. Argon-helium cryoablation was used to assist intracranial tumor resection. Among 7 cases of glioma, 4 cases were totally removed and 3 cases were partially resected. Four cases of meningioma were totally removed. The average intraoperative blood loss was 80 ml, and average operation time was 80 min. Postoperative clinical symptoms were improved, and head CT or MRI showed no rebleeding. Patients were followed up for an average of 4 years, and none of them suffered from operation-related or postoperative complications such as intracranial infection, or tumor recurrence.  Conclusions Argon - helium cryoablation is suitable for intracranial tumors with different diameters and in different locations. It is safe and effective, with few operation-related or postoperative complications, less rebleeding and low risk of recurrence, which is a highly efficient and relatively low?cost assistant surgical method. DOI: 10.3969/j.issn.1672-6731.2017.06.011

    In our study, the effects of harmonic scalpel, scalpel, and monopolar electrocautery usage on the health and healing of colon anastomosis after resection was investigated. In this study, 120 female albino Wistar rats were divided into 3 groups each containing 40 rats. Group A, resection with scalpel; group B, resection with monopolar electrocautery; group C, resection with harmonic scalpel. The groups were divided into 4 subgroups consisting of 10 rats and analysed in the postoperative 1st, 3rd, 5th, and 7th days. Anastomotic bursting pressures, hydroxyproline levels and histopathological parameters were surrogate parameters for evaluating wound healing. The tissue hydroxyproline levels did not show any significant difference between the groups and subgroups. The mean bursting pressure of group A on the 5th day was significantly higher than groups B and C (P anastomosis is planned. Despite the disadvantages of scalpel, its efficacy on early wound healing is better than the other devices.

    Intravenous thrombolysis (IVT) is beneficial in reducing disability in selected patients with acute ischemic stroke. There are numerous contraindications to IVT. One is recent surgery. The aim of this study was to analyze the safety of IVT in patients with postoperative stroke. Data of consecutive IVT patients from the Telemedical Project for Integrative Stroke Care thrombolysis registry (February 2003 to October 2014; n=4848) were retrospectively searched for keywords indicating preceding surgery. Patients were included if surgery was performed within the last 90 days before stroke. The primary outcome was defined as surgical site hemorrhage. Subgroups with major/minor surgery and recent/nonrecent surgery (within 10 days before IVT) were analyzed separately. One hundred thirty-four patients underwent surgical intervention before IVT. Surgery had been performed recently (days 1-10) in 49 (37%) and nonrecently (days 11-90) in 85 patients (63%). In 86 patients (64%), surgery was classified as major, and in 48 (36%) as minor. Nine patients (7%) developed surgical site hemorrhage after IVT, of whom 4 (3%) were serious, but none was fatal. One fatal bleeding occurred remotely from surgical area. Rate of surgical site hemorrhage was significantly higher in recent than in nonrecent surgery (14.3% versus 2.4%, respectively, odds ratio adjusted 10.73; 95% confidence interval, 1.88-61.27). Difference between patients with major and minor surgeries was less distinct (8.1% and 4.2%, respectively; odds ratio adjusted 4.03; 95% confidence interval, 0.65-25.04). Overall in-hospital mortality was 8.2%. Intracranial hemorrhage occurred in 9.7% and was asymptomatic in all cases. IVT may be administered safely in postoperative patients as off-label use after appropriate risk-benefit assessment. However, bleeding risk in surgical area should be taken into account particularly in patients who have undergone surgery shortly before stroke onset. © 2017 American Heart Association, Inc.

    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

    Full Text Available Abstract Background Predicting postoperative lung function is important for estimating the risk of complications and long-term disability after pulmonary resection. We investigated the capability of vibration response imaging (VRI as an alternative to lung scintigraphy for prediction of postoperative lung function in patients with intrathoracic malignancies. Methods Eighty-five patients with intrathoracic malignancies, considered candidates for lung resection, were prospectively studied. The projected postoperative (ppo lung function was calculated using: perfusion scintigraphy, ventilation scintigraphy, and VRI. Two sets of assessments made: one for lobectomy and one for pneumonectomy. Clinical concordance was defined as both methods agreeing that either a patient was or was not a surgical candidate based on a ppoFEV1% and ppoDLCO% > 40%. Results Limits of agreement between scintigraphy and VRI for ppo following lobectomy were -16.47% to 15.08% (mean difference = -0.70%;95%CI = -2.51% to 1.12% and for pneumonectomy were -23.79% to 19.04% (mean difference = -2.38%;95%CI = -4.69% to -0.07%. Clinical concordance between VRI and scintigraphy was 73% for pneumonectomy and 98% for lobectomy. For patients who had surgery and postoperative lung function testing (n = 31, ppoFEV1% using scintigraphic methods correlated with measured postoperative values better than projections using VRI, (adjusted R2 = 0.32 scintigraphy; 0.20 VRI, however the difference between methods failed to reach statistical significance. Limits of agreement between measured FEV1% postoperatively and ppoFEV1% based on perfusion scintigraphy were -16.86% to 23.73% (mean difference = 3.44%;95%CI = -0.29% to 7.16%; based on VRI were -19.56% to 28.99% (mean difference = 4.72%;95%CI = 0.27% to 9.17%. Conclusions Further investigation of VRI as an alternative to lung scintigraphy for prediction of postoperative lung function is warranted.

    Full Text Available OBJECTIVES: The aim of this study was to assess the analgesic efficacy and safety of nonsteroidal anti-inflammatory drugs (NSAIDs, administered as intramuscular diclofenac in comparison with intravenous paracetamol after transurethral resection of the prostate (TURP. MATERIALS AND METHODS: Fifty men, aged 55 to 75 years, undergoing TURP at our hospital were included in this study. Patients were divided randomly and prospectively into two groups (25 patients in each group. Group I (NSAID received 75 mg of diclofenac i.m. at the end of the operation followed by 75 mg of diclofenac i.m. for 24 hours (75 mg x 2 once a day = 150 mg/24 h postoperatively. The other group (Group II consisted of patients who received 1g/100 mL i.v. paracetamol 15 minutes twice daily as postoperative analgesia. Postoperative pain scores were evaluated at 30 minutes, 1, 2, 4 and 6 hours after administration of each analgesic, using a visual analogue scale (VAS. Furthermore, preoperative and postoperative hemoglobin (Hb levels and hemostatic variables (bleeding time, prothrombine time and the international normalized ratio?, i.e. the ratio of a patient's prothrombin time to a normal [control] sample were recorded in all patients. RESULTS: The pain score changes during a 4 hour period between the two groups was similar (p = 0.162. Thirty minutes after surgery, pain scores were high (> 3 cm in both groups and without differences between groups (p = 0.11 but 6 hours after surgery, pain scores were significantly higher with paracetamol compared to diclofenac (p < 0.05. No significant difference was observed between the groups regarding the amount of resected tissue, operating time, preoperative-postoperative Hb levels and hemostatic variables. In the both groups, no patient required blood transfusion postoperatively. CONCLUSIONS: NSAIDs are not a contraindication to TURP and should be used for the control of postoperative pain if indicated.

    Preserving functionality is of significant importance during neurosurgical resection of brain tumors. Specialized centers also map further brain functions apart from motor and language functions, such as arithmetic processing (AP). The mapping of AP by navigated repetitive transcranial magnetic stimulation (nrTMS) in healthy volunteers has been demonstrated. The present study aimed to correlate the results of mapping AP with functional patient outcomes. We included 26 patients with parietal brain tumors. Due to preoperative impairment of AP, mapping was not possible in 8 patients (31%). We stimulated 52 cortical sites by nrTMS while patients performed a calculation task. Pre- and postoperatively, patients underwent a standardized number-processing and calculation test (NPCT). Tumor resection was blinded to nrTMS results, and the change in NPCT performance was correlated to resected AP-positive spots as identified by nrTMS. The resection of AP-positive sites correlated with a worsening of the postoperative NPCT result in 12 cases. In 3 cases, no AP-positive sites were resected and the postoperative NPCT result was similar to or better than preoperatively. Also, in 3 cases, the postoperative NPCT result was better than preoperatively, although AP-positive sites were resected. Despite only presenting a low number of cases, nrTMS might be a useful tool for preoperative mapping of AP. However, the reliability of the present results has to be evaluated in a larger series and by intraoperative mapping data. Copyright © 2018 Elsevier Inc. All rights reserved.

    Protective lung ventilation is reported to benefit patients with acute respiratory distress syndrome. It is not known whether protective lung ventilation is also beneficial to patients undergoing single-lung ventilation for elective pulmonary resection. In an institutional review board-approved prospective randomized trial, 34 patients undergoing elective pulmonary resection requiring single-lung ventilation were enrolled. Informed consent was obtained. Patients were randomized to 1 of 2 groups: (1) high tidal volume (Hi-TV) of 10 mL/kg, rate of 7 breaths/min, and zero positive end-expiratory pressure or (2) low tidal volume (Lo-TV) of 5 mL/kg, rate of 14 breaths/min, and 5 cmH2O positive end-expiratory pressure. Ventilator settings were continued during both double- and single-lung ventilation. Pulmonary functions, hemodynamics, and postoperative outcomes were recorded. Patient demographics, operative characteristics, intraoperative hemodynamics, and postoperative pain and sedation scores were similar between the 2 groups. During most time periods, airway pressures (peak and plateau) were significantly higher in the Hi-TV group; however, plateau pressures remained less than 30 cmH2O at all times for all patients. The Hi-TV group had significantly lower arterial carbon dioxide tension, less arterial carbon dioxide tension-end-tidal carbon dioxide gradient, lower alveolar dead space ratio, and higher dynamic pulmonary compliance. There were no differences in postoperative morbidity and hospital days between the 2 groups, but atelectasis scores on postoperative days 1 and 2 were lower in the Hi-TV group. The use of Hi-TV during single-lung ventilation for pulmonary resection resulted in no increase in morbidity and was associated with less hypercarbia, less dead space ventilation, better dynamic compliance, and less postoperative atelectasis.

    Alterations of thyroid hormones in colorectal surgery were previously studied. The aim of the present study was to determine the effects of triiodothyronine (T3) supplementation on anastomotic healing after segmental colectomy. Thirty male Wistar albino rats were divided into sham (n = 6), control (n = 12), and experimental (n = 12) groups. Sham group rats were immediately sacrificed after segmental colonic resection. Control and experimental group rats underwent resection and anastomosis. Experimental group rats received a single dose of T3 (400 μg/100 g) in postoperative day 1. Half of both control and experimental group rats were sacrificed on postoperative d 3 and the remaining half were sacrificed on postoperative d 7. Hydroxiproline (HP), myeloperoxidase (MPO), thyroid stimulating hormone (TSH), free T3 (FT3), and free thyroxine (FT4) levels, bursting pressure, and histologic analyses of the anastomotic segments were compared. FT3 levels significantly decreased in control groups rats compared with the sham group (P < 0.01). However, T3 hormone given rats had no decline in FT3 levels. Anastomotic bursting pressure was significantly higher in the experimental group rats on postoperative d 7 (P = 0.015). Histopathologic analyses of the anastomotic segments determined significantly more severe edema and necrosis in control group rats (P < 0.05). Collagen deposition in the anastomotic tissue was significantly higher in experimental group rats on postoperative d 7 (P = 0.015). Anastomosis after colon resection is associated with decreased FT3 level. T3 supplementation ameliorates the reduction in FT3 and seems to provide constructive therapeutic effects on anastomotic healing. Copyright © 2012 Elsevier Inc. All rights reserved.

    Brainstem cavernous malformations are associated with a considerable risk of hemorrhage and subsequent morbidity. This study provides a detailed work-up of clinical and radiological outcome as well as identification of prognostic factors in patients who had suffered from symptomatic hemorrhages. Patients who had undergone surgery of symptomatic BSCMs were evaluated pre- and postoperatively both neurologically and neuroradiologically supplemented by telephone interviews. Additionally, patients were scored according to the Scandinavian Stroke Scale. Multiple uni- and multivariate analyses of possible clinical and radiological prognostic factors were conducted. The study population comprised 35 patients. Mean age at operation was 39.3 ± 13.0 years with microsurgical resection of a total of 37 different BSCMs between 2002 and 2011. Median clinical follow-up was 44.0 months (range 8-116 months). Postoperative MRI showed eventually complete resection of all BSCMs. Postoperative overall outcome revealed complete resolution of neurological symptoms for 5/35 patients, 14/35 improved and 9/35 remained unchanged. 7/35 suffered from a postoperative new and permanent neurological deficit, mostly affecting the facial nerve or hemipareses with mild impairment. Pre- and postoperative Scandinavian Stroke Scale scores were 11.0 ± 2.4 and 11.4 ± 2.2 (p = 0.55). None of the analyzed factors were found to significantly correlate with patients' clinical outcome. Complete resection of brainstem cavernous malformations can be achieved with an acceptable risk for long-term morbidity and surgery-related new deficits (~20 %). Neurological outcome is mainly determined within the first 6 months after surgery. Surgical treatment of brainstem cavernous malformations is recommended in symptomatic patients, in whom the lesion is accessible for surgery.

    There is limited data regarding the effects of preoperative dehydration on postoperative renal function. We sought to identify associations between hydration status before operation and postoperative acute renal failure (ARF) in patients undergoing colorectal resection. The NSQIP database was used to examine the data of patients undergoing colorectal resection from 2005 to 2011. We used preoperative blood urea nitrogen (BUN)/creatinine ratio >20 as a marker of relative dehydration. Multivariate analysis using logistic regression was performed to quantify the association of BUN/Cr ratio with ARF. We sampled 27,860 patients who underwent colorectal resection. Patients with dehydration had higher risk of ARF compared to patients with BUN/Cr Dehydration was associated with an increase in mortality of the affected patients (AOR, 2.19; P dehydrated patients. Open colorectal procedures (AOR, 2.67; P = 0.01) and total colectomy procedure (AOR, 1.62; P Dehydration before operation is a common condition in colorectal surgery (incidence of 27.7 %). Preoperative dehydration is associated with increased rates of postoperative ARF, MI, and cardiac arrest. Hydrotherapy of patients with dehydration may decrease postoperative complications in colorectal surgery.

    To investigate whether soft palate resection and tonsillectomy with a bipolar vessel sealing device (BVSD) improves clinical respiratory score. To document histopathological changes to tonsillar tissue following removal with a BVSD. Case series of 22 dogs with clinical signs of upper respiratory obstruction related to brachycephalic airway syndrome. Soft palate and tonsils were removed using a BVSD. Alarplasty and saccullectomy were also performed if indicated. A clinical respiratory score was assigned preoperatively, 24-h postoperatively and 5 weeks postoperatively. Excised tonsillar samples were measured and then assessed histologically for depth of tissue damage deemed to be caused by the device. Depth of tissue damage was compared between two power settings of the device. Soft palate resection and tonsillectomy with a BVSD lead to a significant improvement in respiratory scores following surgery. Depth of tissue damage was significantly less for power setting 1 compared with power setting 2. Using power setting 1, median calculated depth of tonsillar tissue damage was 3.4 mm (range 1.2-8.0). One dog experienced major complications. Soft palate resection and tonsillectomy with a BVSD led to significant improvement in clinical respiratory score. © 2015 Australian Veterinary Association.

    Radical gastrectomy is main treatment of gastric cancer. We analyzed patients with stage III and IV stomach cancer who had radical operation and received postoperative radiation therapy combined with or without chemotherapy retrospectively. From March 1985 to June 1993, 68 patients treated with curative resection and received postoperative adjuvant radiotherapy with 36Gy or more were evaluated. Median age was 60years(range 28-66 yrs). Thirty seven patients had non signet ring adenocarcinoma, 29 signet ring cell, 2 other cell. Patients with stage IIIA, IIIB, IV disease were 19, 25 and 24 respectively. Chemotherapy was given to all patients except two. Five-year overall survival and disease-free survival rate were 36.6% and 33.6T, respectively. Recurrence was documented in 34 patients. High recurrence was seen in omentum and peritoneum with 23.5%, and remnant stomach, anastomosis site, A-loop and E-loop had also high recurrence with 13.2%. In field locoregional recurrence was 20.7% and total distant metastases were 39.7%. Total intraabdominal failure was 47.1% and extraabdominal failure was 13.2%. Treatment toxicity was considered to be acceptable. 22.1% of patients had grade 3 and only 1 patient had grade 4 leukopenia. Six patients(8.8%) had weigh loss more than 10%. Treatment toxicity was acceptable with combined treatment with chemotherapy and radiotherapy. Locoregional recurrence was relatively low compared to distant failure with addition of irradiation. Peritoneal and omental seeding was high. Five-year survival was increased with combined modality. Radiation may eradicate minimal residual disease and improve survival. Furthermore to reduce intraabdominal failure, role of intraabdominal chemotherapy in addition to combined chemotherapy plus radiation has to be explored. (author).

  4. Minimal Invasive Urologic Surgery and Postoperative Ileus

    Full Text Available Postoperative ileus (POI is the most common cause of prolonged length of hospital stays (LOS and associated healthcare costs. The advent of minimal invasive technique was a major breakthrough in the urologic landscape with great potential to progress in the future. In the field of gastrointestinal surgery, several studies had reported lower incidence rates for POI following minimal invasive surgery compared to conventional open procedures. In contrast, little is known about the effect of minimal invasive approach on the recovery of bowel motility after urologic surgery. We performed an overview of the potential benefit of minimal invasive approach on POI for urologic procedures. The mechanisms and risk factors responsible for the onset of POI are discussed with emphasis on the advantages of minimal invasive approach. In the urologic field, POI is the main complication following radical cystectomy but it is rarely of clinical significance for other minimal invasive interventions. Laparoscopy or robotic assisted laparoscopic techniques when studied individually may reduce to their own the duration and prevent the onset of POI in a subset of procedures. The potential influence of age and urinary diversion type on postoperative ileus is contradictory in the literature. There is some evidence suggesting that BMI, blood loss, urinary extravasation, existence of a major complication, bowel resection, operative time and transperitoneal approach are independent risk factors for POI. Treatment of POI remains elusive. One of the most important and effective management strategies for patients undergoing radical cystectomy has been the development and use of enhanced recovery programs. An optimal rational strategy to shorten the duration of POI should incorporate minimal invasive approach when appropriate into multimodal fast track programs designed to reduce POI and shorten LOS.

  5. Prognostic factors of the outcomes of subtotal thyroid resection in graves disease

    Full Text Available The long-term results of subtotal resection of thyroid gland on 82 patients with Graves' disease were studied. There was analysed the influence of three factors on outcome at Graves' disease: volume of a thyroid gland before operation, morphological structure of thyroid tissue and volume of thyroid remnant. Outcomes of subtotal resection of thyroid gland were studied on the basis of thyrotropic hormone level of blood in 3, 6, 12 months, 2 and 3 years after operation. Based on research it has been established that the volume of thyroid gland before operation does not influence to outcome of subtotal resection of thyroid gland with Graves' disease. Morphological changes of removed thyroid tissue in the form of colloidal nodules at patients with Graves' disease statistically significantly raise risk of development of postoperative complications after subtotal resection of thyroid gland. The surgeon defining the volume of thyroid rem-nant durng the operation could be mistaken as towards it's increase so towards it's reduction, with an average deviation about 35%. Various outcomes of subtotal resection of thyroid gland at the same volume of thyroid remnant let us conclude that this out-come depends more on intensity of autoimmune process rather than on the volume of thyroid remnant. According modern views to aetiology and patogenesis of Graves' disease, the optimum volume of operation at Graves' disease is thyroidectomy.

    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 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

    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.

    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.

    Laparoscopic liver resection is used in specialized centers all over the world. However, laparoscopic liver resection has never been compared with open liver resection in a prospective, randomized trial. The Oslo-CoMet Study is a randomized trial into laparoscopic versus open liver resection for the surgical management of hepatic colorectal metastases. The primary outcome is 30-day perioperative morbidity. Secondary outcomes include 5-year survival (overall, disease-free and recurrence-free), resection margins, recurrence pattern, postoperative pain, health-related quality of life, and evaluation of the inflammatory response. A cost-utility analysis of replacing open surgery with laparoscopic surgery will also be performed. The study includes all resections for colorectal liver metastases, except formal hemihepatectomies, resections where reconstruction of vessels/bile ducts is necessary and resections that need to be combined with ablation. All patients will participate in an enhanced recovery after surgery program. A biobank of liver and tumor tissue will be established and molecular analysis will be performed. After 35 months of recruitment, 200 patients have been included in the trial. Molecular and immunology data are being analyzed. Results for primary and secondary outcome measures will be presented following the conclusion of the study (late 2015). The Oslo-CoMet Study will provide the first level 1 evidence on the benefits of laparoscopic liver resection for colorectal liver metastases. The trial was registered in ClinicalTrals.gov (NCT01516710) on 19 January 2012.

    Giant diverticula are rare complications of diverticular disease. Current opinion regards operative therapy as the method of choice for the treatment of symptomatic giant diverticula; however, there is neither consensus about the technique nor about the necessary extent of resection. Based on a non-systematic review of the literature, an overview of giant diverticula in terms of epidemiology, pathology and classification is given. The current case is considered with respect to appropriate diagnostic procedures and possible therapeutic options. An 80-year-old female patient presented to the emergency department with abdominal pain and dyspnea. A computed tomography scan showed a large gas-filled structure in the upper left abdomen adjacent to the left colon. A giant colonic diverticulum was suspected and laparoscopy was performed. Intraoperatively, the diagnosis of a giant colon diverticulum located at the splenic flexure was confirmed. An unremarkable diverticulosis only was found in the descending colon. The giant diverticulum was treated by an atypical colon wedge resection and the postoperative course was uneventful. This case report describes a laparoscopic atypical colon wedge resection as treatment of a giant colon diverticulum. Only four laparoscopic bowel resections in terms of sigmoid resections or hemicolectomy with primary anastomosis have been reported. Minimally invasive surgery can be a valuable alternative to open procedures. In the current case a laparoscopic atypical colon wedge resection was safely performed. This option might be considered as an alternative to extended resections of giant diverticula. Localization of the giant diverticulum and the simultaneous existence of diverticular disease are the main criteria for the decision between the different operative approaches.

    In this study 30 patients with symptomatic epilepsy caused by cavernomas were investigated in a postoperative follow up study to assess predictors for postoperative outcome with respect to indications, time and approach of surgery. Thirty patients with cavernomas refractory to medical treatment were scheduled for surgery based on the findings of high-resolution MR imaging and intensive EEG-video monitoring. Postoperative outcome of epilepsy was assessed by follow-up examinations based on the basis of classification by Engel and the International League against epilepsy (ILAE). The following variables were associated with good postoperative outcome: (1) complete resection of hemosiderin fringe surrounding the cavernoma was correlated to less postoperative seizure frequency versus incomplete resection of the hemosiderin fringe according to the outcome protocol of ILAE. (2) Lower duration of epilepsy at the time of operation was correlated to a better postoperative outcome with a benefit for recovery. (3) Absence of hemorrhage before surgery and unifocal seizure onset was a predictor for a favorable outcome, whereas bilateral or multifocal seizure onset zones showed poorer postoperative outcomes. (4) In patients with dual pathology (hippocampal sclerosis in addition to a cavernoma), lesionectomy plus hippocampectomy as opposed to lesionectomy only, had a better outcome than single lesionectomy. Postoperative outcome in patients with cavernomas should be the topic of further prospective multicenter studies involving a large number of patients. In addition to the ideal operation time and handling of dual pathology the role of extended resection including perilesional hemorrhages should be taken into account.

    Postoperative pulmonary complications (PPCs) are a major contributor to the overall risk of surgery. PPCs affect the length of hospital stay and are associated with a higher in-hospital mortality. PPCs are even the leading cause of death either in cardiothoracic surgery but also in non-cardiothoracic surgery. Thus, reliable PPCs risk stratification tools are the key issue of clinical decision making in the perioperative period. When the risk is clearly identified related to the patient according the ARISCAT score and/or the type of surgery (mainly thoracic and abdominal), low-cost preemptive interventions improve outcomes and new strategies can be developed to prevent this risk. The EuSOS, PERISCOPE and IMPROVE studies demonstrated this care optimization by risk identification first, then risk stratification and new care (multifaceted) strategies implementation allowing a decrease in PPCs mortality by optimizing the clinical path of the patient and the care resources.

    The failed back surgery syndrome (FBSS) is one of the most perplexing medical and medicoeconomic problems facing our health system today. In many studies reoperation rates tend to be between 10 and 20%, but as many as 20-45% 3 of patients may have persistent back or radicular pain following what was to have been definitive therapy. The causes for the FBSS are very complex. The Workmen's Compensation system and medicolegal trends toward very high settlements of litigation for injury have provided serious incentive for patients to remain symptomatic. It is difficult to analyze any statistical survey of symptomatic back patients without serious bias from this group of patients. Others suggest that patients with severe psychological problems, drug abuse, and alcoholism are inappropriately selected as surgical candidates. They believe that careful psychological evaluation of patients minimizes FBSS. Even if all extrinsic factors could be eliminated, the problem of failed back surgery would still be a major one. This chapter is based on a review of 300 postoperative lumbar spine multiplanar CT scans performed over a 15-month period. All patients had a complete set of axial images, with sagittal and coronal reformations photographed twice: optimized once for bone definition and once for soft-tissue contrast resolution

    To avoid hormonal replacement after partial adrenalectomy (PA), establishing the precise limit of an adrenal gland resection is essential. Herein, we evaluated the use of three-dimensional (3D) adrenal gland printing and volumetry measurement before PA to improve the determination of the remnant gland volume. Concomitant total adrenalectomy and a contralateral PA were performed in a patient with primary macronodular adrenal hyperplasia that exhibited mild hypercortisolism, arterial hypertension, and diabetes. Before surgery, a 3D replica of the adrenal gland to be partially resected was printed and given to the surgeon. The volumetry of the gland was measured by computed tomography 3D image reconstruction. No postoperative complications were noted. Immediately after the surgery, the patient initiated corticosteroid replacement, which was interrupted 52 days later. At the 6-month follow-up, the patient stopped using medications for diabetes and reduced the number of antihypertensive medications from 5 to 1. The pre- and postoperative serum cortisol levels were, respectively, 28 and 8.7 mcg/dl (n 5-25 mcg/dl). The pre- and postoperative adrenocorticotropic hormone levels were, respectively, <5 and 88 pg/ml (n 7.2-63 pg/ml). The postoperative adrenal volume was 12% of the total preoperative adrenal volume. The use of 3D printing associated with adrenal volumetry might be a useful tool for the surgeon when performing PA, enabling an estimation of the remnant gland volume. Copyright © 2016 Elsevier Inc.

    Hearing restoration after translabyrinthine vestibular schwannoma resection is a challenge. Because the cochlea can begin to ossify a few months after cochlear or labyrinthine injury, the time interval for cochlear implant surgery is limited. To avoid complete ossification and to prolong the time interval until cochlear implantation, it is possible to insert a placeholder (depth gauge) into the cochlea and perform the cochlear implant surgery at a later time point (two-stage approach). The aim of this retrospective case series was to present the outcomes after restoration of hearing with cochlea implants in six patients and to evaluate the use of the depth gauge in practice. The hearing outcome of all patients with (n = 3) and without (n = 3) insertion of a depth gauge was measured with the Freiburg monosyllabic test without background noise at 65 dB. The first measurement was performed prior to the translabyrinthine vestibular schwannoma resection, the last measurement was performed up to 48 months after cochlear implantation. All 6 patients reached 22.5 ± 36.57% prior to vestibular schwannoma resection and 41.3 ± 26% 12 months after cochlear implantation. The understanding values of the patients with a depth gauge were 25.8 ± 16% after 12 months which is below the values of the other patients with 56.6 ± 25.0%. No severe intraoperative or postoperative complications occurred in any patient. The two-stage approach for cochlear implantation with depth gauge insertion following labrynthine incision and intact nerve appears to represent a very promising and safe variation for hearing restoration. Intensified research on this approach seems to be justified and necessary.

    Full Text Available Pancreatic cancer is an aggressive malignancy with a poor prognosis. The disease and its treatment can cause significant nutritional impairments that often adversely impact patient quality of life (QOL. The pancreas has both exocrine and endocrine functions and, in the setting of cancer, both systems may be affected. Pancreatic exocrine insufficiency (PEI manifests as weight loss and steatorrhea, while endocrine insufficiency may result in diabetes mellitus. Surgical resection, a central component of pancreatic cancer treatment, may induce or exacerbate these dysfunctions. Nutritional and metabolic dysfunctions in patients with pancreatic cancer lack characterization, and few guidelines exist for nutritional support in patients after surgical resection. We reviewed publications from the past two decades (1995–2016 addressing the nutritional and metabolic status of patients with pancreatic cancer, grouping them into status at the time of diagnosis, status at the time of resection, and status of nutritional support throughout the diagnosis and treatment of pancreatic cancer. Here, we summarize the results of these investigations and evaluate the effectiveness of various types of nutritional support in patients after pancreatectomy for pancreatic adenocarcinoma (PDAC. We outline the following conservative perioperative strategies to optimize patient outcomes and guide the care of these patients: (1 patients with albumin < 2.5 mg/dL or weight loss > 10% should postpone surgery and begin aggressive nutrition supplementation; (2 patients with albumin < 3 mg/dL or weight loss between 5% and 10% should have nutrition supplementation prior to surgery; (3 enteral nutrition (EN should be preferred as a nutritional intervention over total parenteral nutrition (TPN postoperatively; and, (4 a multidisciplinary approach should be used to allow for early detection of symptoms of endocrine and exocrine pancreatic insufficiency alongside implementation of

    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.

    2016-11-01

    The upper extremity is an uncommon site for deep vein thrombosis and, although most of these thrombotic events are secondary to catheters or indwelling devices, venous thoracic outlet syndrome is an important cause of primary thrombosis. Young, active, otherwise healthy individuals that engage in repetitive upper extremity exercises, such as those required by a military vocation, may be at an increased risk. We present the case of a Naval Officer diagnosed with venous thoracic outlet syndrome whereby a multimodal approach with early surgical decompression was used. Although thoracic outlet decompression by means of first rib resection is the standard of care, timing of first rib resection after thrombolysis is debated. With respect to the active duty service member, the optimal timing of additional postoperative interventions for residual venous defects and duration of anticoagulation remain in question. A more streamlined perioperative treatment regimen may benefit the military patient without jeopardizing the quality of care and allow more expeditious return to full duty.

  3. Endoscopic endonasal resection of cavernous hemangioma of the palate

    2017-11-01

    Full Text Available Hemangiomas are a common presentation in the head and neck, but intraosseous hemangiomas are exceedingly rare and account for only 1% of bone tumors. The hard palate is a unique anatomic structure consisting of mucosa rich in minor salivary glands, and is firmly attached to the palatine process of the maxilla and the horizontal plate of the palatine bone. Neoplasms of the hard palate are extremely rare and may display unique characteristics and histologic findings. Whether benign or malignant, the therapy of choice for such tumors is surgical excision performed through a transoral approach, which carries a significant risk of oronasal and oroantral fistula formation. This paper describes the use of an endoscopic endonasal technique for resection of a rare case of a cavernous hemangioma of the hard palate. Resection of favorable benign lesions like palatal hemangiomas are more likely to be successful via this endoscopic endonasal technique which avoids the traditional transoral palatal approach and thus reduces the risk of oronasal and oroantral fistulae. No complications in the immediate postoperative nor within a 1-year follow-up period were observed.

    2013-08-01

    Liver resection in patients with underlying liver disease remains a formidable challenge. It requires adequate patient selection, a precise surgical plan, and avoidance of additional ischemic insults during surgery. Precise estimation of the residual liver volume using computed tomography or magnetic resonance imaging and computer-assisted volumetry allows the calculation of residual to total liver volume (RLV/TLV) ratios. Although RLV/TLV ratios over 20 to 25% are considered sufficient in healthy livers, patients with cirrhosis may only tolerate resections that result in RLV/TLV ratios over 40% and higher. Conventional laboratory tests may not be able to sufficiently predict liver reserve after resection. Dynamic tests such as indocyanine green clearance have been used to assess residual liver function and assist in deciding about operability of patients with underlying liver disease undergoing extensive resections. Intraoperative management should focus on avoiding blood loss and ischemic injury to the liver. Low central venous pressure may reduce blood loss and is recommended if tolerated without impeding renal perfusion. Portal vein and hepatic artery occlusion during resection can reduce blood loss, but will cause ischemic insult to the liver that may jeopardize residual liver function and induce postoperative hepatic failure. When feasible, vascular occlusion should be avoided in patients with underlying liver disease. The postoperative recovery is usually fast if sufficient liver remains. However, vigilance is required to detect liver dysfunction and treat its complications. Thieme Medical Publishers 333 Seventh Avenue, New York, NY 10001, USA.

    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.

To administer the Stroop test intraoperatively to avoid dramatic side effects such as akinetic mutism and to monitor executive functions in an attempt to optimize the benefit/risk balance of surgery. A series of 9 adult patients with frontal glioma were operated on for gross tumor resection under local anesthesia. All procedures involved the anterior cingulate cortex (ACC). Three types of response to the Stroop test were observed: 3 patients had a Stroop effect only for stimulation of the contralateral ACC; 3 patients had a Stroop effect for stimulation of the ipsilateral ACC; and 3 patients had no Stroop effect. Preoperative and postoperative neuropsychological and surgical results are presented and discussed. Stimulation sites eliciting a Stroop effect are compared with published image-based data, and insight provided by these surgical data regarding ACC function and plasticity is discussed. No operative complication related to intraoperative administration of the Stroop test was observed. Administration of the Stroop test during resection of gliomas involving the ACC in adult patients is an option for intraoperative monitoring of executive functions during awake surgery. Globally, these results suggest functional compensation, mediated by plasticity mechanisms, by contralateral homologous regions of the ACC in adult patients with frontal glioma.

    Ileocecal resection (ICR), one of several types of intestinal resection that results in short bowel syndrome (SBS), causes severe clinical disease in humans. We here describe a mouse model of massive ICR in which 75% of the distal small intestine is removed. We demonstrate that mice underwent 75% ICR show severe clinical signs and high mortality, which may recapitulate severe forms of human SBS, despite an adaptive response throughout the remnant intestine. By using this model, we also investigated whether the epithelium of the remnant intestine shows enhanced expression of factors involved in region-specific functions of the ileum. Cubn mRNA and its protein product, which play an essential role in vitamin B12 absorption in the ileum, are not compensatory up-regulated in any part of the remnant intestine, demonstrating a clear contrast with post-operative up-regulation of genes involved in bile acid absorption. Our study suggests that functional adaptation by phenotypical changes in the intestinal epithelium is not a general feature for nutrient absorption systems that are confined to the ileum. We also propose that the mouse model developed in this study will become a unique system to facilitate studies on SBS with ICR in humans. © 2017. Published by The Company of Biologists Ltd.

  11. Biliary Stricture Following Hepatic Resection

    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.

    This study was performed to analyze the factors affecting local control in malignant tumors of the parotid gland treated with surgery and postoperative radiation. Twenty-six patients were treated for malignant tumors of the parotid gland from 1986 to 1995 at Department of Therapeutic Radiology. Chonnam University Hospital. Age of the patients ranged from 14 to 72 years (median: 55 years). Histologically 10 patients of mucoepidermoid carcinoma, 7 of squamous cell carcinoma. 4 of acinic cell carcinoma, 4 of adenoid cystic carcinoma and 1 of adenocarcinoma were treated. Total parotidectomy was performd in 15 of 26 patients, superficial in 7, subtotal in 4. Facial nerve was sacrificed in 5 patients. Postoperatively 4 patients had residual disease, 4 had positive resection margin. Radiation was delivered through an ipsilateral wedged pair of photon in 11 patients. High energy electron beam was mixed with photon in 15 patients. Electron beam dose ranged from 900 cGy to 3800 cGy (median: 1760 cGy). Total radiation dose ranged from 5000 cGy to 7560 cGy (median: 6020 cGy). Minimum follow-up period was 2 years. Local control and survival rate were calculated using Kaplan-Meier method. Generalized Wilcoxon test and Cox proportional hazard model were used to test factors affecting local control. Five (19%) of 26 patients had local recurrence. Five year local control rate was 77%. Overall five year survival rate was 70%. Sex, age, tumor size, surgical involvement of cervical lymph node, involvement of resection margin, surgical invasion of nerve, and total dose were analyzed as suggested factors affecting local control rate. Among them patients with tumor size less than 4 cm (p=0.002) and negative resection margin (p= 0.011) were associated with better local control rates in univariate analysis

    Standard treatment for urachal adenocarcinomas is open partial cystectomy and urachal resection; however, minimally invasive surgical approaches including laparoscopic and recently described robotic assisted laparoscopic partial cystectomy and urachal resection is feasible with potential less morbidity. A case of robotic assisted partial cystectomy and urachal resection for urachal adenocarcinoma is presented. Few articles in the literature have being published describing this technique and to the best of our knowledge, this is the largest and potentially most complex case approached in such a manner. A 55 years old African American male presented with hematuria and mucosuria, cystoscopy demonstrated a tumor involving the dome of the bladder. Transurethral biopsy confirmed a urachal adenocarcinoma. Further studies revealed a negative metastatic evaluation. Preoperative abdominal/pelvic CT imaging revealed an enhancing mass extending from the inferior level of the umbilicus to the dome of the bladder. A total of 6 laparoscopic ports were used. The robotic assisted laparoscopic dissection was started at the level of the umbilicus, dissecting lateral to the right and left medial umbilical ligaments up until the dome of the bladder. A simultaneous cystoscopy with transillumination to define the bladder boundaries of this mass, with robotic assisted laparoscopic opening of the bladder, with the entire mass (including bladder component) excised and sent for frozen pathology for margin evaluation. After specimen extraction, the bladder was closed in two layers. Total surgery time was 300 minutes and intra-operative blood loss was 150cc. Final pathology reported a pT2N0Mx adenocarcinoma with negative margins and negative pelvic lymph nodes. Patient was started on clear liquids on postoperative day 2 and on regular diet on postoperative day 3. He was discharged on postoperative day 4. A cystogram perfomed on postoperative day 7 revealed a good bladder capacity (350 cc) and

    To compare transumbilical laparoendoscopic single-site surgery with conventional laparoscopy for the resection of retroperitoneal paragangliomas. In the present case-control study, we compared 11 transumbilical laparoendoscopic single-site surgery procedures with 22 conventional laparoscopy procedures carried out to treat retroperitoneal paragangliomas between June 2004 and October 2013 at Peking Union Medical Hospital, Beijing, China. Operative time, estimated intraoperative blood loss, blood transfusions, intraoperative hypertension, intraoperative hypotension, highest intraoperative systolic blood pressure, lowest intraoperative systolic blood pressure, postoperative fatigue time, postoperative systematic inflammation reaction syndrome, 24-h postoperative visual analog scale scores, postoperative hospital stay duration, and postoperative complications were recorded and analyzed. There were no significant differences in patient characteristics. All surgical procedures were successfully completed in both groups. Minor complications occurred in one case in the laparoendoscopic single-site surgery group and in two cases in the conventional laparoscopy group. In the laparoendoscopic single-site surgery group, the operative time was longer than that in the conventional laparoscopy group (P = 0.001). There were no significant differences in terms of intraoperative hypertension, intraoperative hypotension, highest intraoperative systolic blood pressure, lowest intraoperative systolic blood pressure, estimated blood loss, postoperative fatigue time, postoperative hospital stay or systematic inflammation reaction syndrome between the two groups. The 24-h postoperative visual analog scale score was lower in the laparoendoscopic single-site surgery group (P = 0.002). No recurrence or metastases were observed over the duration of the postoperative follow up. In properly selected patients, transumbilical laparoendoscopic single-site surgery is a feasible, safe and effective

    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.

    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.

    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.

    Radiotherapy has long been the treatment of choice for local control of Ewing sarcoma of the chest wall (ESCW). However, there is debate regarding the use of surgery versus RT. Our objective was to identify risk factors that may affect long-term outcomes of non-metastatic ESCW all treated with preoperative chemotherapy followed by en-bloc resection and adjuvant Chemotherapy or Chemoradiation. Between 1996 and 2014, 30 patients with a median age of 25 years (SD +/-8.9) were treated at our institution. Adjuvant therapy was used in 27 patients: Chemotherapy for 6 of them, Chemoradiation for 20, and Radiotherapy for 1. Patient demographics, treatment data, tumor features, and outcomes were collected. In this cohort that received multimodal therapy, including neo-adjuvant chemotherapy and en-bloc resection, there was no postoperative mortality. Eight patients (27%) experienced postoperative complications. Resection included at least one rib (n= 27) and the sternum (n=1) or the spine (n= 8). Negative and microscopic disease resections were achieved in 28 and 2 patients, respectively. Tumor viability (TV) was ≤5% in 18 patients (60%). In patients with TV > 5% at definitive histology, adjuvant Chemoradiation was associated with better long-term outcome than adjuvant chemotherapy alone. 5-year overall survival and disease-free survival were 60.7% and 41.0%, respectively, with a median survival of 87 months. By univariate analysis, TV > 5% and pleural extension at diagnosis were associated with poorer long-term survival (p<0.05). Multimodality treatment of ESCW, including neoadjuvant Chemotherapy followed by en-bloc resection and adjuvant Chemotherapy or Chemoradiation, is associated with excellent long-term outcomes.

    Full Text Available Postoperative ileus is among the most common complications after surgery. Aging is associated with an increased colonic transit time, and anesthetic disturbance to colonic motility is often aggravated in the elderly. Postoperative ileus increases morbidity, prolongs the length of hospital stay, and constitutes a significant economic burden on the healthcare system. Multimodal enhanced recovery protocols, or fast-track surgeries, have been developed to improve postoperative recovery. Patient education, avoidance of perioperative fluid overload, selective use of nasogastric decompression, early ambulation, adopting a minimally invasive approach, early initiation of clear fluids, and gum chewing are all possible measures to reduce postoperative ileus.
