To evaluate the morbidity and mortality of laparoscopic cystectomy combined with transileal ureterostomy to treat neurogenic vesicosphincteric disorders. Prospective study performed between february 2004 and april 2006 on 26 consecutive patients with a mean age of 55.0 +/- 12.7 years treated by laparoscopic cystectomy for neurogenic vesicosphincteric disorders. The underlying neurological disease was multiple sclerosis (MS) in 20 cases, spinal cord injury in 4 cases and transverse myelitis in 2 cases. The median preoperative ASA score was 3 (range: 2-3). No open conversion was necessary. One intraoperative complication was observed (vascular injury). No perioperative death was observed. The nasogastric tube was maintained postoperatively for an average of 8.69 +/- 5.9 hours. The mean time to resumption of oral fluids was 1.4 +/- 0.7 days and mean time to resumption of solids was 2.6 +/- 1.0 days. The mean time to resumption of bowel movements was 3.8 +/- 3.2 days. The mean intensive care stay was 3.9 +/- 1.1 days. Two postoperative complications were observed in the same patient (ileus and bronchial congestion). Postoperative narcotic analgesics were necessary in 60% of cases. The mean hospital stay was 10.3 +/- 4.1 days. Two late postoperative complications were observed in the same patient (two episodes of pyelonephritis). Laparoscopic cystectomy has a low morbidity in neurological patients, allowing early return of feeding and a moderate length of hospital stay.

Despite the large number of analytical reports regarding the learning curve in the transition from open to robot-assisted radical prostatectomy (RARP), few comparative results with laparoscopic radical prostatectomy (LRP) have been reported. Thus, we evaluated operative and postoperative outcomes in RARP versus 100 simultaneously performed LRPs. A single surgeon had performed more than 1,000 laparoscopic operations, including 415 cases of radical nephrectomy, 85 radical cystectomies, 369 radical prostatectomies, and treatment of 212 other urological tumors, since 2009. We evaluated operative (operation time, intraoperative transfusion, complications, hospital stay, margin status, pathological stage, Gleason score) and postoperative (continence and erectile function) parameters in initial cases of RARP without tutoring compared with 100 recently performed LRPs. Mean operation time and length of hospital stay for RARP and LRP were 145.5±43.6 minutes and 118.1±39.1 minutes, and 6.4±0.9 days and 6.6±1.1 days, respectively (p=0.003 and p=0.721). After 17 cases, the mean operation time for RARP was similar to LRP (less than 2 hours). Positive surgical margins in localized cancer were seen in 11.1% and 8.9% of cases in RARP and LRP, respectively (p=0.733). At postoperative 3 months, sexual intercourse was reported in 14.0% and 12.0%, and pad-free continence in 96.0% and 81.0% in patients with RARP and LRP, respectively (p=0.796 and p=0.012). Previous large-volume experience of LRPs may shorten the learning curve for RARP in terms of oncological outcome. Additionally, previous experience with laparoscopy may improve the functional outcomes of RARP.

Full Text Available The development of infiltrative bladder carcinoma in patients previously treated with radical prostatectomy due to prostate adenocarcinoma represents a challenging perspective. Radical cystectomy remains the best option for invasive bladder cancer, however, there are few reports about the best approach to such individuals. Nevertheless, despite possible technical difficulties found during surgery, the orthotopic urinary shunt is a reasonable option in selected cases.

Radical cystectomy is a surgical treatment for recurrent non-muscle-invasive and muscle-invasive bladder cancer; however, many patients may not receive this treatment. A total of 27,578 patients diagnosed with clinical stage I-IV bladder cancer from 1 January 2007 to 31 December 2013 were identified from the Surveillance, Epidemiology, and End Results (SEER) registry database. We used multivariable regression analyses to identify factors predicting the use of radical cystectomy and pelvic lymph node dissection. Cox proportional hazards models were used to analyze survival outcomes. A total of 1,693 (6.1%) patients with bladder cancer underwent radical cystectomy. Most patients (92.4%) who underwent radical cystectomy also underwent pelvic lymph node dissection. When compared with white patients, non-Hispanic blacks were less likely to undergo a radical cystectomy [odds ratio (OR) 0.79, 95% confidence interval (CI) 0.64-0.96, p = 0.019]. Moreover, recent year of surgery 2013 versus 2007 (OR 2.32, 95% CI 1.90-2.83, p groups diagnosed with bladder cancer, especially among older, non-Hispanic black patients.

A case of moving ileal Taenia saginata parasites is presented with demonstrative images. We came across the parasites surprisingly while performing robot-assisted laparoscopic radical cystoprostatectomy with intracorporeal Studer pouch urinary diversion. We recommend stool sample evaluation in the preoperative period for possible presence of intestinal parasitic diseases, particularly in patients with bladder cancer who are admitted from areas with an increased incidence of intestinal parasitic diseases, before opening the bowel segments during surgery to perform radical cystectomy and urinary diversion.

Full Text Available While open radical cystectomy remains the gold-standard treatment for muscle-invasive bladder cancer and high-risk non–muscle invasive disease, robotic assisted radical cystectomy (RARC has been gaining popularity over the past decade. The robotic approach has the potential advantages of less intraoperative blood loss, shorter hospital stay, less post-operative narcotic requirement, quicker return of bowel function, and earlier convalescence with an acceptable surgical learning curve for surgeons adept at robotic radical prostatectomy. While short to intermediate term oncologic results from several small RARC series are promising, bladder cancer remains a potentially lethal malignancy necessitating long-term follow-up. This article aims to review the currently published literature, important technical aspects of the operation, oncologic and functional outcomes, and the future direction of RARC.

The standard treatment for patients with early-stage cervical cancer has been radical hysterectomy. However, for women interested in future fertility, radical trachelectomy is now considered a safe and feasible option. The use of minimally invasive surgical techniques to perform this procedure has recently been reported. We report the first case of a laparoscopic radical trachelectomy performed in a developing country. The patient is a nulligravid, 30-y-old female with stage IB1 adenocarcinoma of the cervix who desired future fertility. She underwent a laparoscopic radical trachelectomy and bilateral pelvic lymph node dissection. The operative time was 340 min, and the estimated blood loss was 100mL. There were no intraoperative or postoperative complications. The final pathology showed no evidence of residual disease, and all pelvic lymph nodes were negative. At 20 mo of follow-up, the patient is having regular menses but has not yet attempted to become pregnant. There is no evidence of recurrence. Laparoscopic radical trachelectomy with pelvic lymphadenectomy in a young woman who desires future fertility may also be an alternative technique in the treatment of early cervical cancer in developing countries.

We hypothesized that in patients with T2N0 stage disease at transurethral bladder tumor resection a lower residual cancer stage (P1N0 or less) at radical cystectomy may correlate with improved outcomes relative to those with residual P2N0 disease. We analyzed 208 patients with T2N0 stage disease at transurethral bladder tumor resection whose tumors were organ confined at radical cystectomy (P2 or lower, pN0). None received perioperative chemotherapy. Kaplan-Meier as well as univariable and multivariable Cox regression models addressed the effect of residual pT stage at radical cystectomy on recurrence and cancer specific mortality rates. Covariates consisted of age, gender, grade, lymphovascular invasion, carcinoma in situ, number of lymph nodes removed and year of surgery. Residual pT stage at radical cystectomy was P0 in 24 (11.5%) patients, Pa in 9 (4.3%), PCIS in 22 (10.6%), P1 in 35 (16.8%) and P2 in 118 (56.7%). Median followup of censored patients was 55.7 months for recurrence and 52.1 months for cancer specific mortality analyses. The 5-year recurrence-free survival rates of patients with P0/Pa/PCIS, P1 and P2 stage disease were 100%, 85% and 75%, respectively. The 5-year cancer specific survival rates for the same cohorts were 100%, 93% and 81%, respectively. On multivariable analysis the effect of residual stage P1 or lower at radical cystectomy achieved independent predictor status for recurrence (adjusted HR 0.20, p = 0.002) and cancer specific mortality (adjusted HR 0.24, p = 0.02). Down staging from initial T2N0 bladder cancer at transurethral bladder tumor resection to lower stage at radical cystectomy significantly reduces recurrence and cancer specific mortality. Further validation of this finding is warranted.

Full Text Available Purpose: Robot-assisted radical cystectomy (RARC was originally intended to replace open radical cystectomy (ORC as a minimally invasive surgery for patients with invasive bladder cancer. The purpose of this study was to evaluate the advantages of robotic surgery, comparing perioperative and oncologic outcomes between RARC and ORC. Materials and Methods: Between June 2012 and August 2016, 49 bladder cancer patients were given a radical cystectomy, 21 robotically and 28 by open procedure. We compared the clinical variables between the RARC and ORC groups. Results: In the RARC group, the median estimated blood loss (EBL during cystectomy, total EBL, operative time during cystectomy, and total operative time were 0 mL, 457.5 mL, 199 minutes, and 561 minutes, respectively. EBL during cystectomy (p<0.001, total EBL (p<0.001, and operative time during cystectomy (p=0.003 in the RARC group were significantly lower compared with the ORC group. Time to resumption of a regular diet (p<0.001 and length of stay (p=0.017 were also significantly shorter compared with the ORC group. However, total operative time in the RARC group (median, 561 minutes was significantly longer compared with the ORC group (median, 492.5 minutes; p=0.015. Conclusions: This Japanese study presented evidence that RARC yields benefits in terms of BL and time to regular diet, while consuming greater total operative time. RARC may be a minimally invasive surgical alternative to ORC with less EBL and shorter length of stay.

Radical cystectomy is the gold-standard treatment for muscle-invasive and refractory nonmuscle-invasive bladder cancer. We describe our technique for robotic radical cystectomy (RRC) and intracorporeal urinary diversion (ICUD), that replicates open surgical principles, and present our preliminary results. Specific descriptions for preoperative planning, surgical technique, and postoperative care are provided. Demographics, perioperative and 30-day complications data were collected prospectively and retrospectively analyzed. Learning curve trends were analyzed individually for ileal conduits (IC) and neobladders (NB). SAS(®) Software Version 9.3 was used for statistical analyses with statistical significance set at P < 0.05. Between July 2010 and September 2013, RRC and lymph node dissection with ICUD were performed in 103 consecutive patients (orthotopic NB=46, IC 57). All procedures were completed robotically replicating the open surgical principles. The learning curve trends showed a significant reduction in hospital stay for both IC (11 vs. 6-day, P < 0.01) and orthotopic NB (13 vs. 7.5-day, P < 0.01) when comparing the first third of the cohort with the rest of the group. Overall median (range) operative time and estimated blood loss was 7 h (4.8-13) and 200 mL (50-1200), respectively. Within 30-day postoperatively, complications occurred in 61 (59%) patients, with the majority being low grade (n = 43), and no patient died. Median (range) nodes yield was 36 (0-106) and 4 (3.9%) specimens had positive surgical margins. Robotic radical cystectomy with totally ICUD is safe and feasible. It can be performed using the established open surgical principles with encouraging perioperative outcomes.

To confirm gender specific differences in pathologic factors and survival rates of urothelial bladder cancer patients treated with radical cystectomy. We conducted a retrospective monocentric study on 701 patients treated with radical cystectomy and pelvic lymphadenectomy for muscle invasive bladder cancer. Impact of gender on recurrence rate, specific and non-specific mortality rate were evaluated using Cox regression models in univariate and multivariate analysis. We collected data on 553 males (78.9%) and 148 females (21.1%) between 1998 and 2011. Both groups were comparable at inclusion regarding age, pathologic stage, nodal status and lymphovascular invasion. Mean follow-up time was 45 months (interquartile 23-73) and by that time, 163 patients (23.3%) had recurrence of their tumor and 127 (18.1%) died from their disease. In multivariable Cox regression analyses, female gender was independently associated with disease recurrence (RR: 1.73; 95% CI 1.22-2.47; P=0.02) and cancer-specific mortality (RR=2.50, 95% CI=1.71-3.68; P<0.001). We confirmed female gender to be an independent negative prognosis factor for patients following a radical cystectomy and lymphadenectomy for an invasive muscle bladder cancer.

We instituted a ketamine-predominant analgesic regimen in the peri- and postoperative periods to limit the effects of narcotic analgesia on bowel function in patients undergoing radical cystectomy. The primary end points of interest were time to return of bowel function, time to discharge, and efficacy of the analgesic regimen. We performed a retrospective chart review of patients undergoing robotic-assisted laparoscopic cystectomy (RARC) with urinary diversion by a single surgeon at our institution from January 1, 2011 to June 30, 2012. Patients receiving the opioid-minimizing ketamine protocol were compared to a cohort of patients undergoing RARC with an opioid-predominant analgesic regimen. In total, 15 patients (Group A) were included in the ketamine-predominant regimen and 25 patients (Group B) in the opioid-predominant control group. Three patients (19%) in Group A discontinued the protocol due to ketamine side effects. The mean time to bowel movement and length of stay in Group A versus Group B was 3 versus 6 days (p return of bowel function and length of hospitalization after RARC. Our study has its limitations as a retrospective, single surgeon, single institution study and the non-randomization of patients. Notwithstanding these limitations, this study was not designed to show inferiority of one approach, but instead to show that our protocol is safe and efficacious, warranting further study in a prospective fashion.

Full Text Available Partial/extended partial cystectomy (EPC is the most common surgery done for localized urachal malignancies. However, sometimes, after EPC, patients may be left with small bladder remnant, reconstruction of which will result in very small capacity bladder with resultant severe storage voiding symptoms. We report a case of urachal adenocarcinoma, in which when a small bladder remnant was left post-EPC, instead of proceeding with radical cystectomy (RC and neobladder (the standard alternative, bladder augmentation was done with good oncological and voiding outcome. Augmentation cystoplasty has many advantages over neobladder and we suggest it as an oncologically comparable alternative to RC with neobladder, which has been underutilized in urachal malignancies as we found on literature review.

Preservation of Ejaculatory and Erectile Function after Radical Cystectomy for Urothelial Malignancy

Treating cancer patients, sexual issues should not be forgotten. With increasing survival from urologic cancer, quality of life and quality of sexuality have became very important targets in treating those patients. Fertility to those patients who desire fatherhood is sometimes more important than cancer morbidity, especially young patients in the rural areas in our country, to the extent that they may refuse the operation. We describe a new technique to preserve the erectile function and antegrade ejaculation after radical cystectomy. Patients and Methods: Seven potent men with a median age of 40 years (range 35-50) presented with invasive transitional cell carcinoma (TCC) of the lateral or the anterior bladder wall. All patients wished to preserve the ejaculatory function and fertility potential. We described the surgical technique of nerve sparing radical cystectomy with preservation of the vas deferens, seminal vesicles, whole prostate and neurovascular bundles. The follow up period ranged from six months to three years (mean 20 months) to assess recurrence, erectile function and ejaculatory function. Erectile function is normal in all patients with satisfactory sexual intercourse. Antegrade ejaculation was documented in six cases. One of them fathered a child. No local or distant recurrence was detected in the seven patients at the last follow-up. The technique of radical cystectomy (with preservation of the vas deferens, whole prostate and seminal vesicle) is a good option in selected young men with bladder carcinoma in whom preservation of fertility is desirable

To perform a cost analysis comparing the cost of robot-assisted radical cystectomy (RARC) with open RC (ORC) in a UK tertiary referral centre and to identify the key cost drivers. Data on hospital length of stay (LOS), operative time (OT), transfusion rate, and volume and complication rate were obtained from a prospectively updated institutional database for patients undergoing RARC or ORC. A cost decision tree model was created. Sensitivity analysis was performed to find key drivers of overall cost and to find breakeven points with ORC. Monte Carlo analysis was performed to quantify the variability in the dataset. One RARC procedure costs £12 449.87, or £12 106.12 if the robot was donated via charitable funds. In comparison, one ORC procedure costs £10 474.54. RARC is 18.9% more expensive than ORC. The key cost drivers were OT, LOS, and the number of cases performed per annum. High ongoing equipment costs remain a large barrier to the cost of RARC falling. However, minimal improvements in patient quality of life would be required to offset this difference. © 2017 The Authors BJU International © 2017 BJU International Published by John Wiley & Sons Ltd.

Prediction of mortality after radical cystectomy for bladder cancer by machine learning techniques.

Bladder cancer is a common cancer in genitourinary malignancy. For muscle invasive bladder cancer, surgical removal of the bladder, i.e. radical cystectomy, is in general the definitive treatment which, unfortunately, carries significant morbidities and mortalities. Accurate prediction of the mortality of radical cystectomy is therefore needed. Statistical methods have conventionally been used for this purpose, despite the complex interactions of high-dimensional medical data. Machine learning has emerged as a promising technique for handling high-dimensional data, with increasing application in clinical decision support, e.g. cancer prediction and prognosis. Its ability to reveal the hidden nonlinear interactions and interpretable rules between dependent and independent variables is favorable for constructing models of effective generalization performance. In this paper, seven machine learning methods are utilized to predict the 5-year mortality of radical cystectomy, including back-propagation neural network (BPN), radial basis function (RBFN), extreme learning machine (ELM), regularized ELM (RELM), support vector machine (SVM), naive Bayes (NB) classifier and k-nearest neighbour (KNN), on a clinicopathological dataset of 117 patients of the urology unit of a hospital in Hong Kong. The experimental results indicate that RELM achieved the highest average prediction accuracy of 0.8 at a fast learning speed. The research findings demonstrate the potential of applying machine learning techniques to support clinical decision making. Copyright © 2015 Elsevier Ltd. All rights reserved.

We examined whether the presence and severity of preoperative hydronephrosis have prognostic significance in patients who underwent radical cystectomy for transitional cell carcinoma of the bladder. The medical records of 457 patients who underwent radical cystectomy for bladder cancer between 1986 and 2005 were retrospectively reviewed. Following the Society for Fetal Urology grading system, patients were divided into low-, and high-grade hydronephrosis groups. Clinicopathologic factors associated with preoperative hydronephrosis and survival were evaluated. Of a total of 406 patients, unilateral hydronephrosis was found in 74 (18.2%), bilateral hydronephrosis in 11 (2.7%), and no hydronephoris in 321 (79.1%). Low-grade hydronephrosis was found in 57 (12.2%) patients and high-grade hydronephrosis in 28 (6%). Preoperative hydronephrosis was related to higher pT stage and lymph node invasion. In univariate analysis, the presence of hydronephrosis, hydronephrosis grade, age, pT and pN stage, tumor grade, surgical margin, number of retrieved nodes, carcinoma in situ, and lymphovascular invasion were significant prognostic factors for cancer-specific survival. In multivariate analysis, bilateral hydronephrosis and high-grade hydronephrosis remained significant predictors for decreased survival. The presence of preoperative hydronephrosis, and high-grade hydronephrosis are significant prognostic factors in patients with bladder cancer after radical cystectomy. PMID:20191034

To identify symptom distress and clusters in patients 3 months after radical cystectomy and to explore their potential predictors. A cross-sectional design was used to investigate 99 bladder cancer patients 3 months after radical cystectomy. Data were collected by demographic and disease characteristic questionnaires, the symptom experience scale of the M.D. Anderson symptom inventory, two additional symptoms specific to radical cystectomy, and the functional assessment of cancer therapy questionnaire. A factor analysis, stepwise regression, and correlation analysis were applied. Three symptom clusters were identified: fatigue-malaise, gastrointestinal, and psycho-urinary. Age, complication severity, albumin post-surgery (negative), orthotropic neobladder reconstruction, adjuvant chemotherapy and American Society of Anesthesiologists (ASA) scores were significant predictors of fatigue-malaise. Adjuvant chemotherapy, orthotropic neobladder reconstruction, female gender, ASA scores and albumin (negative) were significant predictors of gastrointestinal symptoms. Being unmarried, having a higher educational level and complication severity were significant predictors of psycho-urinary symptoms. The correlations between clusters and for each cluster with quality of life were significant, with the highest correlation observed between the psycho-urinary cluster and quality of life. Bladder cancer patients experience concurrent symptoms that appear to cluster and are significantly correlated with quality of life. Moreover, symptom clusters may be predicted by certain demographic and clinical characteristics.

Full Text Available OBJECTIVE: To characterize the frequency and timing of complications following radical cystectomy in a cohort of patients treated at community and academic hospitals. PATIENTS AND METHODS: Radical cystectomy patients captured from NSQIP hospitals from January 1 2006 to December 31 2012 were included. Baseline information and complications were abstracted by study surgical clinical reviewers through a validated process of medical record review and direct patient contact. We determined the incidence and timing of each complication and calculated their associations with patient and operative characteristics. RESULTS: 2303 radical cystectomy patients met inclusion criteria. 1115 (48% patients were over 70 years old and 1819 (79% were male. Median hospital stay was 8 days (IQR 7-13 days. 1273 (55.3% patients experienced at least 1 post-operative complication of which 191 (15.6% occurred after hospital discharge. The most common complication was blood transfusion (n = 875; 38.0%, followed by infectious complications with 218 (9.5% urinary tract infections, 193 (8.4% surgical site infections, and 223 (9.7% sepsis events. 73 (3.2% patients had fascial dehiscence, 82 (4.0% developed a deep vein thrombosis, and 67 (2.9% died. Factors independently associated with the occurrence of any post-operative complication included: age, female gender, ASA class, pre-operative sepsis, COPD, low serum albumin concentration, pre-operative radiotherapy, pre-operative transfusion >4 units, and operative time >6 hours (all p<0.05. CONCLUSION: Complications remain common following radical cystectomy and a considerable proportion occur after discharge from hospital. This study identifies risk factors for complications and quality improvement needs.

Neoadjuvant chemotherapy (NC) before minimally invasive radical cystectomy (MIRC) is considered a standard of care in muscle-invasive bladder cancer or recurrent high-risk non-muscle-invasive bladder cancer. To evaluate the impact of NC on morbidity and mortality after MIRC. We prospectively evaluated 135 patients who underwent MIRC (laparoscopic: n=100; robotic: n=35) between 2007 and 2013 with ≥90 days of follow-up (median age: 66 year). Complications were analyzed and graded according to the Clavien Dindo classification system. Logistic regression models were used to evaluate the impact of NC on postoperative complications. Kaplan-Meier methods with the log-rank test were used for cancer-specific survival probabilities and differences between the 2groups (MIRC with and without NC). Sixty-two of 135 patients received NC. A total of 118 patients (87.4%) developed 179 complications, chiefly infectious (48.0%) or gastrointestinal (21.2%), ≤90 days after surgery; 3 patients died bladder cancer who had NC versus no NC. We did not find any significant differences in terms of early or late complications, length of stay, or reintervention. The oncologic outcomes regarding NC were encouraging. Copyright © 2016.

Full Text Available The psychological impact on patients suffering radical cystectomy is twofold - (both that of the underlying neoplastic disease and that measured by the quality of life subsequent to surgery and increases as the urinary derivation technique is less physiological and affects more the local anatomy. Although there are numerous questionnaires that assess the quality of life of patients with cancer (HRQoL - health related QoL, not many probe bladder cancer morbidity or correlate the different types of urinary diversions’ impact on QoL (quality of life. We analyzed 39 cases in our clinic who underwent radical cystectomy between August 2013 and August 2014. Different diversions were performed, as follows: for 24 patients a cutaneous ureterostomy was performed, in 10 cases a Mainz II pouch, in 3 cases a Bricker derivation and in 2 patients a Studer neobladder was performed. In these patients, QoL - Cancer Version and FACT-BL questionnaires were administered and were followed for an initial period of 2 years. According to our survey, the Bricker derivation is best tolerated, followed by neobladder and the Mainz II pouch.

Full Text Available Ovarian cysts are the most common cause of pelvic masses in women. Although laparoscopic surgery is considered the gold standard treatment for ovarian cysts, most of the large ovarian cysts continue to be treated by laparotomy due to technical difficulties. Laparoscopic-assisted cystectomy is an alternative operation type for managing such cases. A case of large ovarian cyst with adnexal torsion in a 21-year-old virgin patient is presented in this report. In this case laparoscopic-assisted cystectomy was performed without intraoperatif complication. Postoperative course was uneventful. Pathology revealed a benign serous cystadenoma. At 6 months follow up, she continued to be asymptomatic, and sonography showed no recurrence of her disease. Laparoscopic-assisted cystectomy is a safe and effective procedure for large adnexal cysts.

We aimed to evaluate the impact of topical hemostatic sealants and bipolar coagulation during laparoscopic ovarian endometriotic cyst resection on ovarian reserve by comparing the rates of decrease in anti-Müllerian hormone (AMH). A randomized prospective data collection was made on women aged 19-45 years who planned to have laparoscopic ovarian cystectomy at one of two institutions (n = 80), Kangbuk Samsung Hospital, Seoul, Korea or National Health Insurance Service Ilsan Hospital, Goyang, Korea, from January 2014 to April 2016. Patients were randomly divided into two groups treated with either a topical hemostatic sealant or bipolar coagulation for hemostasis. The hemostatic group was randomized to the FloSeal or TachoSil subgroups. Preoperative and 3-month postoperative AMH levels were checked and the rates of decrease of AMH were compared. All patients enrolled were treated with dienogest (Visanne) for 6-12 months. None were lost to follow-up at postoperative 3 months, but about one-third of the patients had been lost to follow-up by 6-12 months. AMH was significantly decreased in both groups 3 months postoperatively; however, the rate of decrease in the bipolar coagulation group was greater than that in the hemostatic sealant group, 41.9% (interquartile range [IQR], 22.29-65.24) versus 18.1% (IQR, 10.94-29.90), P = 0.007. Between the two hemostatic subgroups, there was no significant difference in AMH decrease rate, 14.95% (IQR, 11.34-21.21) versus 18.1% (IQR 9.76-40.70), P = 0.204. Hemostatic sealants may be an alternative to bipolar coagulation for preservation of ovarian reserve after laparoscopic ovarian cystectomy for endometriosis. © 2017 Japan Society of Obstetrics and Gynecology.

To assess morbidity and functional consequences of laparoscopic cystectomy with ileal conduit urinary diversion: in neurologic patients. We reviewed the records of forty-two patients (ten men and thirty-two women) who underwent surgery between August 2007 and October 2013. The median age of the patient was 54 years old (range between 21-79 years). A laparoscopic cystectomy was performed followed by a short laparotomy to perform the ileal conduit urinary diversion. Records were reviewed to retrieve the indications and describe the postoperative and functional course. Patients and GPs were interviewed during phone calls to appreciate the quality of life by the PGII scale in order to assess the functional outcome. The operation was performed on 42 patients, of whom 18 had multiple sclerosis, nine a post-traumatic neurogenic bladder. Among the total population, 10 patients (23.81%) required a transfusion of at least one packed red blood cells (1-7). The overall rate of early complications was 35.71%. Belated complications were seen in 52.38% of the population. The median duration of hospital stay was 16 days (range between 9-70 days). The median follow up was 34 months (range between 1-76 months). For patients, the PGII scale rating had a median value of 6 (2-7). All referring physicians described a better functional status. The laparoscopic cystectomy can make postoperative course smoother for the neurological patients. However, the surgeon must weigh individually the benefit of performing the operation.

The aim of this report is to describe our surgical technique of totally intracorporeal robotic assisted radical cystectomy (RARC) with neobladder formation. Between December 2003 and March 2013, a total of 147 patients (118 male, 29 female) underwent totally intracorporeal RARC for urinary bladder cancer. We also performed a systematic search of Medline, Embase and PubMed databases using the terms RARC, robotic cystectomy, robot-assisted, totally intracorporeal RARC, intracorporeal neobladder, intracorporeal urinary diversion, oncological outcomes, functional outcomes, and complication rates. The mean age of our patients was 64 years (range 37-87). On surgical pathology 47% had pT1 or less disease, 27% had pT2, 16% had pT3 and 10% had pT4. The mean number of lymph nodes removed was 21 (range 0-60). 24% of patients had lymph node positive dAQ1isease. Positive surgical margins occurred in 6 cases (4%). Mean follow-up was 31 months (range 4-115 months). Two patients (1.4%) died within 90 days of their operation. Using Kaplan-Meier analysis, overall survival and cancer specific survival at 60 months was 68% and 69.6%, respectively. 80 patients (54%) received a continent diversion with totally intracorporeal neobladder formation. In the neobladder subgroup median total operating time was 420 minutes (range 265-760). Daytime continence and satisfactory sexual function or potency at 12 months ranged between 70-90% in both men and women. Our experience with totally intracorporeal RARC demonstrates acceptable oncological and functional outcomes that suggest this is a viable alternative to open radical cystectomy.

Purpose: Radical trachelectomy is a fertility-sparing procedure with the aim to provide adequate oncological safety to patients with cervical cancer while preserving their fertility. The purpose of this study was to retrospectively evaluate, in a series of 3 patients, the feasibility, morbidity, and safety of laparoscopically assisted vaginal radical trachelectomy for early cervical cancer. Patients and Methods: Three non consecutive patients with FIGO stage IA1 and IB1 cervical cancer was evaluated in a period of years 2008 - 2011. The patients underwent a laparoscopic pelvic lymphadenectomy and radical parametrectomy class II procedure according to the Piver classification. The section of vaginal cuff, trachelectomy, permanent cerclage and isthmo-vaginal anastomosis ware realised by vaginal approach. Results: The median operative time, the median blood loss and the mean number of resected pelvic nodes was comparable with published data. Major intraoperative complications did not occur and no patient required a blood transfusion. The median follow-up time was 33 (38-59) months. One vaginal recurrence occurred in 7 months after primary surgery. The patient was underwent a radicalisation procedure and adjuvant oncologic therapy and now is free of disease. Conclusions: Laparoscopically assisted vaginal radical trachelectomy (LAVRT)may be an alternative in fertility-preserving surgery for early cervical cancer. The procedure offers patients potential benefits of minimally invasive surgery with adequate oncological safety, but it should be reserved for oncologic surgeons trained in advanced laparoscopic procedures.

Clostridium Difficile is the most common cause of nosocomial infectious diarrhea. This study evaluates the prevalence and predictors of Clostridium Difficile infections in patients undergoing radical cystectomy with or without neoadjuvant chemotherapy. Retrospective chart review was performed of all patients undergoing cystectomy and urinary diversion at a single institution from 2011-2017. Infection was documented in all cases with testing for Clostridium Difficile polymerase chain reaction toxin B. Patient and disease related factors were compared for those who received neoadjuvant chemotherapy vs. those who did not in order to identify potential risk factors associated with C. Difficile infections. Chi squared test and logistic regression analysis were used to determine statistical significance. Of 350 patients who underwent cystectomy, 41 (11.7%) developed Clostridium Difficile in the 30 day post-operative period. The prevalence of C. Difficile infection was higher amongst the patients undergoing cystectomy compared to the non-cystectomy admissions at our hospital (11.7 vs. 2.9%). Incidence was not significantly different among those who underwent cystectomy for bladder cancer versus those who underwent the procedure for other reasons. Median time to diagnosis was 6 days (range 3-28 days). The prevalence of C. Diff infections was not significantly different among those who received neoadjuvant chemotherapy vs. those who did not (11% vs. 10.4% p  = 0.72). A significant association between C. Difficile infection was not seen with proton pump inhibitor use ( p  = 0.48), patient BMI ( p  = 0.67), chemotherapeutic regimen ( p  = 0.94), individual surgeon ( p  = 0.54), type of urinary diversion (0.41), or peri-operative antibiotic redosing ( p  = 0.26). Clostridium Difficile infection has a higher prevalence in patients undergoing cystectomy. No significant association between prevalence and exposure to neoadjuvant chemotherapy was seen.

Objective: To investigate clinical outcomes of laparoendoscopic single-site ovarian cystectomy compared with traditional multi-port laparoscopic ovarian cystectomy. Methods: Data of 81 patients with ovarian cystectomy from January 2016 to May 2017, the single-site group ( n= 40) and the multi-port group ( n= 41) in Peking Union Medical College Hospital were retrospectively collected. The outcomes of single-site and multi-port groups were analyzed and compared, including: postoperative fever, operation time, blood loss, hemoglobin change, surgical complications, postoperative pain score, postoperative analgesic requirements, body image scale and cosmetic score, length of hospital stay, postoperative total cost. Results: No complication was found in two groups. No difference was found in postoperative fever, blood loss, hemoglobin change, postoperative pain score, length of hospital stay, and total cost between the two groups (all P> 0.05). Operation time was (50±20) minutes in single-site group, and (40±15) minutes in multi-port group; postoperative analgesic requirements was 28%(11/40) in single-site group, and 7%(4/41) in multi-port group; cosmetic score was 22.6±2.6 in single-site group, and 17.3±2.6 in multi-port group; body image scale was 5.7±1.2 in single-site group, and 6.2±1.2 in multi-port group; these four clinical parameters were statistical differences (all P< 0.05). Conculsion: Laparoendoscopic single-site ovarian cystectomy is feasible and safe, although it could't relieve the postoperative pian, it do offer a higher cosmetic satisfaction.

To establish the current standard for open radical cystectomy (ORC) in England, as data entry by surgeons performing RC to the British Association of Urological Surgeons (BAUS) database was mandated in 2013 and combining this with Hospital Episodes Statistics (HES) data has allowed comprehensive outcome analysis for the first time. All patients were included in this analysis if they were uploaded to the BAUS data registry and reported to have been performed in the 2 years between 1 January 2014 and 31 December 2015 in England (from mandate onwards) and had been documented as being performed in an open fashion (not laparoscopic, robot assisted or the technique field left blank). The HES data were accessed via the HES website. Office of Population Censuses and Surveys Classification of Surgical Operations and Procedures version 4 (OPCS-4) Code M34 was searched during the same 2-year time frame (not including M34.4 for simple cystectomy or with additional minimal access codes Y75.1-9 documenting a laparoscopic or robotic approach was used) to assess data capture. A total of 2 537 ORCs were recorded in the BAUS registry and 3 043 in the HES data. This indicates a capture rate of 83.4% of all cases. The median operative time was 5 h, harvesting a median of 11-20 lymph nodes, with a median blood loss of 500-1 000 mL, and a transfusion rate of 21.8%. The median length of stay was 11 days, with a 30-day mortality rate of 1.58%. This is the largest, contemporary cohort of ORCs in England, encompassing >80% of all performed operations. We now know the current standard for ORC in England. This provides the basis for individual surgeons and units to compare their outcomes and a standard with which future techniques and modifications can be compared. © 2018 The Authors BJU International © 2018 BJU International Published by John Wiley & Sons Ltd.

Inflammatory Myofibroblastic Tumor of the Bladder: 2 Rare Cases Managed with Laparoscopic Partial Cystectomy

2016-01-01

Full Text Available Two cases of inflammatory myofibroblastic tumor (IMT of the bladder are reported here. Both patients were male and presented with macroscopic hematuria; in the first case terminal hematuria was associated with irritative voiding symptoms. The second case was a smoker with hematuria unresponsive to medical treatment and anemia. Clinical presentation, pathological features, treatment, and prognosis are discussed. Due to rarity of this pathological condition, there are no guidelines concerning treatment and follow-up. We present our follow-up scheme and highlight the use of laparoscopic partial cystectomy as a successful treatment approach.

Full Text Available Transitional cell carcinoma (TCC of the urothelium is often multifocal and subsequent tumors may occur anywhere in the urinary tract after the treatment of a primary carcinoma. Patients initially presenting a bladder cancer are at significant risk of developing metachronous tumors in the upper urinary tract (UUT. We evaluated the prognostic factors of primary invasive bladder cancer that may predict a metachronous UUT TCC after radical cystectomy. The records of 476 patients who underwent radical cystectomy for primary invasive bladder TCC from 1989 to 2001 were reviewed retrospectively. The prognostic factors of UUT TCC were determined by multivariate analysis using the COX proportional hazards regression model. Kaplan-Meier analysis was also used to assess the variable incidence of UUT TCC according to different risk factors. Twenty-two patients (4.6%. developed metachronous UUT TCC. Multiplicity, prostatic urethral involvement by the bladder cancer and the associated carcinoma in situ (CIS were significant and independent factors affecting the occurrence of metachronous UUT TCC (P = 0.0425, 0.0082, and 0.0006, respectively. These results were supported, to some extent, by analysis of the UUT TCC disease-free rate by the Kaplan-Meier method, whereby patients with prostatic urethral involvement or with associated CIS demonstrated a significantly lower metachronous UUT TCC disease-free rate than patients without prostatic urethral involvement or without associated CIS (log-rank test, P = 0.0116 and 0.0075, respectively. Multiple tumors, prostatic urethral involvement and associated CIS were risk factors for metachronous UUT TCC, a conclusion that may be useful for designing follow-up strategies for primary invasive bladder cancer after radical cystectomy.

The aim of the present study was to determine the influence of intraoperative and postoperative blood transfusion on cancer-specific outcome. Follow-up data were collected from 722 patients undergoing radical cystectomy for urothelial carcinoma of the bladder (UCB) between 2004 and 2014. Median follow-up was 26 months (interquartile range 12-61 months). Outcome was analyzed in relation to the amount of intraoperative and postoperative blood transfusion and different tumor stages. The primary endpoint was cancer-specific survival (CSS) after cystectomy. Kaplan-Meier analysis with log-rank test and Cox regression models were used. Intraoperative blood transfusion was given in 36% (263/722) and postoperative blood transfusion in 18% (132/722). In patients with and without intraoperative blood transfusion, 5 year CSS was 48% and 67%, respectively (p blood transfusion, 5 year CSS was 48% and 63%, respectively (p transfused red blood cell (RBC) units [intraoperatively: hazard ratio (HR) = 1.08, 95% confidence interval (CI) 1.01-1.15, p = .023; postoperatively: HR = 1.14, 95% CI 1.07-1.21, p transfusions was also found in favorable subgroups (pT1 tumor, hemoglobin ≥13 mg/dl, p = .004) and in a high-volume surgeon subgroup (n = 244, p Blood transfusions during and after radical cystectomy were independent prognostic factors for CSS in this retrospective study. Therefore, efforts should be made to reduce the necessity of intraoperative and postoperative blood transfusion in cystectomy patients.

In this study, we compared perioperative and oncologic outcomes of patients treated with either open or robot-assisted radical cystectomy and intracorporeal neobladder at a tertiary care center. The institutional prospective bladder cancer database was queried for "cystectomy with curative intent" and "neobladder". All patients underwent robot-assisted radical cystectomy and intracorporeal neobladder or open radical cystectomy and orthotopic neobladder for high-grade non-muscle invasive bladder cancer or muscle invasive bladder cancer with a follow-up length ≥2 years were included. A 1:1 propensity score matching analysis was used. Kaplan-Meier method was performed to compare oncologic outcomes of selected cohorts. Survival rates were computed at 1,2,3 and 4 years after surgery and the log rank test was applied to assess statistical significance between the matched groups. Overall, 363 patients (299 open and 64 robotic) were included. Open radical cystectomy patients were more frequently male (p = 0.08), with higher pT stages (p = 0.003), lower incidence of urothelial histologies (p = 0.05) and lesser adoption of neoadjuvant chemotherapy (open radical cystectomy cases (all p ≥ 0.22). Open cohort showed a higher rate of perioperative overall complications (91.3% vs 42.2%, p 0.001). At Kaplan-Meier analysis robotic and open cohorts displayed comparable disease-free survival (log-rank p = 0.746), cancer-specific survival (p = 0.753) and overall-survival rates (p = 0.909). Robot-assisted radical cystectomy and intracorporeal neobladder provides comparable oncologic outcomes of open radical cystectomy and orthotopic neobladder at intermediate term survival analysis.

The benefits and adverse effects of post-operative irradiation for advanced bladder cancer patients were investigated. Ten patients with pT3b, pT4 or pN+ bladder cancer who underwent radical cystectomy at Yamanashi Medical University Hospital during 7 years and 3 months from October 1983 to December 1991 received adjuvant chemotherapy and radiotherapy (Group 1). During the same period, six patients with recurrent tumor after radical cystectomy were treated by radiotherapy (Group II). Stages of the primary tumors were PT2 in 1, pT3a in 2, pT3b in 6 and pT4 in 7 cases. In addition, 10 of 16 patients (63%) had positive nodes. During the follow-up period, seven patients died of cancer, and one died of other cause. As a result eight patients (5 in Group I, 3 in Group II) are alive. The cumulative 5-year survival rate is 50%. However, nine of the 16 patients (56%) suffered from the small bowel obstruction as an adverse effect of irradiation. Six patients required resection of the small bowel or bypass surgery. Radiation after radical cystectomy seemed to be effective for the local control of the tumor, but the adverse effect to the digestive system was very severe and common. (author)

Radical cystectomy for bladder cancer is associated with a high risk of needing red blood cell transfusion. Tranexamic acid reduces blood loss during cardiac and orthopedic surgery, but no study has yet evaluated tranexamic acid use during cystectomy. A randomized, double-blind (surgeon-, anesthesiologist-, patient-, data-monitor-blinded), placebo-controlled trial of tranexamic acid during cystectomy was initiated in June 2013. Prior to incision, the intervention arm participants receive a 10 mg/kg loading dose of intravenously administered tranexamic acid, followed by a 5 mg/kg/h maintenance infusion. In the control arm, the patient receives an identical volume of normal saline that is indistinguishable from the intervention. The primary outcome is any blood transfusion from the start of surgery up to 30 days post operative. There are no strict criteria to mandate the transfusion of blood products. The decision to transfuse is entirely at the discretion of the treating physicians who are blinded to patient allocation. Physicians are allowed to utilize all resources to make transfusion decisions, including serum hemoglobin concentration and vital signs. To date, 147 patients of a planned 354 have been randomized to the study. This protocol reviews pertinent data relating to blood transfusion during radical cystectomy, highlighting the need to identify methods for reducing blood loss and preventing transfusion in patients receiving radical cystectomy. It explains the clinical rationale for using tranexamic acid to reduce blood loss during cystectomy, and outlines the study methods of our ongoing randomized controlled trial.

To evaluate the impact on ovarian reserve between two different methods ofhemostasis after laparoscopic ovarian endometrioma excision. A randomized controlled study was conducted from January to December 2013 in Thammasat University Hospital, Thailand. Reproductive women, age 18-45years who underwent laparoscopic ovarian cystectomy were randomized in electrocoagulation and suture groups. Clinical baseline data and ovarian reserve outcome (anti-Mullerian hormone (AMH)) were evaluated. Fifty participants were recruited and randomized in two groups. Electrocoagulation and suture groups consisted of 25 participants. Baseline characteristics between 2 groups (age, weight, BMI, height, cyst diameter, duration and estimated blood loss) were not statistically different. There were no significant difference of AMIH between electrocoagulation and suture group atpre-operative (2.90±2.26 vs. 2.52±2.37 ng/ml), 1 week (1.78±1.51 vs. 1.99±1.71 ng/ml), 1 month (1.76±1.50 vs. 2.09±1.62 ng/ml), 3 months (2.09±1.66 vs. 1.96±1.68 ng/ml) and 6 months (2.11±1.84 vs 1.72±1.68 ng/ml), respectively. However mean AMH ofboth groups significantly decreased since the first week of operation. Effect oflaparoscopic ovarian surgery had significantly declined and sustained AMH level until 6 months. Laparoscopic cystectomy of ovarian endometrioma has negative impact to ovarian reserve. Either electroco- agulation or suture method had no different effects.

Full Text Available ABSTRACT Introduction and Objective Radical cystectomy (RC with pelvic lymph node dissection is the standard treatment for muscle invasive bladder cancer and the oncologic outcomes following it are directly related to disease pathology and surgical technique. Therefore, we sought to analyze these features in a cohort from a Brazilian tertiary oncologic center and try to identify those who could negatively impact on the disease control. Patients and Methods We identified 128 patients submitted to radical cystectomy, for bladder cancer treatment, from January 2009 to July 2012 in one oncology tertiary referral public center (Mario Penna Institute, Belo Horizonte, Brazil. We retrospectively analyzed the findings obtained from their pathologic report and assessed the complications within 30 days of surgery. Results We showed similar pathologic and surgical findings compared to other large series from the literature, however our patients presented with a slightly higher rate of pT4 disease. Positive surgical margins were found in 2/128 patients (1.5%. The medium number of lymph nodes dissected were 15. Major complications (Clavien 3 to 5 within 30 days of cystectomy occurred in 33/128 (25.7% patients. Conclusions In the management of invasive bladder cancer, efforts should focus on proper disease diagnosis and staging, and, thereafter, correct treatment based on pathologic findings. Furthermore, extended LND should be performed in all patients with RC indication. A critical analysis of our complications in a future study will help us to identify and modify some of the factors associated with surgical morbidity.

To evaluate, in a prospective study, the clinical outcome of orthotopic neobladder reconstruction after radical cystectomy in patients with a solitary functioning kidney at the time of surgery. Patients and methods: This study included a total of 28 patients (25 males and three females) with muscle invasive bladder cancer and a solitary functioning kidney at the time of surgery who underwent radical cystectomy (anterior pelvic excentration for females) and urinary reconstruction using orthotopic neobladder at The National Cancer Institute, Cairo University between February 2004 and April 2009. The surgical procedures included ileocaecal neobladder in 19 patients, ileal neobladder (Studer) in five and sigmoid neobladder in four. All perioperative and long-term complications were recorded. The renal functions were evaluated using mainly serum creatinine level, abdominal ultrasonography and intravenous urography (IVU). Results: The mean age of patients was 51.4 years (range of 38-62 years) while the mean follow-up period was 41.4 months (range 18-62 months). Early complications included wound infections in five patients, urine leakage in six, abdominal dehiscence with deep venous thrombosis in two, intestinal obstruction and prolonged ileus in three. During the follow-up period, 21 renal units (75%) remained stable with normal serum creatinine level and normal radiological configuration of the kidney. The remaining seven patients (25%) developed varying degrees of renal deterioration either due to uretero-intestinal stricture in three patients (10.7%), who were all treated by open surgical revision of the anastomotic sites or due to stricture at the vesico-urethral anastomosis in four patients (14.3%) that had been successfully managed by endoscopic dilatation and internal ure-throtomy with stabilization of renal function. Severe metabolic acidosis occurred in one patient while mild forms occurred in three. These four patients required sodium bicarbonate therapy and

We histologically examined the urethral anatomy to assess whether the surgical procedure for radical cystectomy should be modified in females. Anatomical and histological studies were performed on 20 adult female cadavers. Semiserial sections were processed for histological examination and immunohistochemistry. To assess the clinical value of the antegrade approach we examined blood loss and function in 12 consecutive patients who underwent radical cystectomy by this approach. Vaginal wall smooth muscle contributed to urethral wall formation, in addition to a thin layer of proper urethral smooth muscle, particularly when the bladder detrusor was poorly developed or degenerated. The middle urethra was attached tightly to the vaginal smooth muscles with abundant veins running at the interface. The urethral sphincter and its inferoposterior continuation (urethrovaginal sphincter) were embedded in the elastic fiber rich perineal membrane. The membrane was U shaped, wrapping around the anterior aspect of the middle urethra and extending posterior along the distal vagina to end at the lateral extension of the perineal body near the external anal sphincter. Mean estimated blood loss was 965 ml. Of patients who received a neobladder hypercontinence was observed in 14.3% and 57.1% achieved continence. There is topographical variation in the anatomy of tissues surrounding the female urethra. Care should be taken when dissecting the tissues dorsal or lateral to the urethra. The antegrade approach is useful since the urethra can be dissected under direct vision and traction can be applied to these structures.

The purpose of this study was to determine the feasibility of performing laparoscopic radical prostatectomy in a canine model. Laparoscopic radical prostatectomy was performed on six adult male canines. A new endoscopic needle driver was used to construct a secure vesicourethral anastomosis. Average operative time required to complete the procedure was 304 min (range 270-345 min). Dissection of the prostate gland took an average of 67 min (range 35-90 min), and construction of the vesicourethral anastomosis took 154 min (rage 80-240 min). There were no intraoperative complications and only one postoperative complication (anastomotic leak). Five of the six animals recovered uneventfully from the procedure, and their foley catheters were removed 10-14 days postoperatively after a retrograde cystourethrogram demonstrated an intact vesicourethral anastomosis. Four (80%) of the surviving animals were clinically continent within 10 days after catheter removal. Post mortem examination confirmed that the vesicourethral anastomosis was intact with no evidence of urine extravasation. These data demonstrate the feasibility of laparoscopic radical prostatectomy in a canine model, and suggest that additional work with this technique should be continued to develop its potential clinical application.

In radical cystectomy, under-nutrition is common and has detrimental physiological and clinical effects, which can lead to increased complications and prolonged recovery. This article compares measurements and outcomes across continents in this patient population with advanced bladder cancer. The association of preoperative nutritional risk, nutritional status, and length of stay is equal across continents, and the results promote increased clinical awareness that women at severe risk should be identified preoperatively.

Pertinent issues related to laparoscopic radical prostatectomy

Full Text Available PURPOSE: We describe the critical steps of the laparoscopic radical prostatectomy (LRP technique and discuss how they impact upon the pertinent issues regarding prostate cancer surgery: blood loss, potency and continence. RESULTS: A major advantage of LRP is the reduced operative blood loss. The precise placement of the dorsal vein complex stitch associated with the tamponading effect of the CO2 pneumoperitoneum significantly decrease venous bleeding, which is the main source of blood loss during radical prostatectomy. At the Cleveland Clinic, the average blood loss of our first 100 patients was 322.5 ml, resulting in low transfusion rates. The continuous venous bleeding narrowed pelvic surgical field and poor visibility can adversely impact on nerve preservation during open radical prostatectomy. Laparoscopy, with its enhanced and magnified vision in a relatively bloodless field allows for excellent identification and handling of the neurovascular bundles. During open retropubic radical prostatectomy, the pubic bone may impair visibility and access to the urethral stump, and the surgeon must tie the knots relying on tactile sensation alone. Consequently, open prostatectomy is associated with a prolonged catheterization period of 2 - 3 weeks. Comparatively, during laparoscopic radical prostatectomy all sutures are meticulously placed and each is tied under complete visual control, resulting in a precise mucosa-to-mucosa approximation. CONCLUSION: The laparoscopic approach may represent a reliable less invasive alternative to the conventional open approach. Despite the encouraging preliminary anatomical and functional outcomes, prospective randomized comparative trials are required to critically evaluate the role of laparoscopy for this sophisticated and delicate operation.

While robotic assisted radical nephrectomy is safe with outcomes and complication rates comparable to those of the pure laparoscopic approach, there is little evidence of an economic or clinical benefit. From the 2009 to 2011 Nationwide Inpatient Sample database we identified patients 18 years old or older who underwent radical nephrectomy for primary renal malignancy. Robotic assisted and laparoscopic techniques were noted. Patients treated with the open technique and those with evidence of metastatic disease were excluded from analysis. Descriptive statistics were performed using the chi-square and Mann-Whitney tests, and the Student t-test. Multiple linear regression was done to examine factors associated with increased hospital costs and charges. We identified 24,312 radical nephrectomy cases for study inclusion, of which 7,787 (32%) were performed robotically. There was no demographic difference between robotic assisted and pure laparoscopic radical nephrectomy cases. Median total charges were $47,036 vs $38,068 for robotic assisted vs laparoscopic surgery (p robotic assisted surgery were $15,149 compared to $11,735 for laparoscopic surgery (p robotic assistance conferred an estimated $4,565 and $11,267 increase in hospital costs and charges, respectively, when adjusted for adapted Charlson comorbidity index score, perioperative complications and length of stay (p Robotic assisted radical nephrectomy results in increased medical expense without improving patient morbidity. Assuming surgeon proficiency with pure laparoscopy, robotic technology should be reserved primarily for complex surgeries requiring reconstruction. Traditional laparoscopic techniques should continue to be used for routine radical nephrectomy. Copyright © 2014 American Urological Association Education and Research, Inc.

Background: Radical cystectomy is associated with perioperative complication rates exceeding 50% in some series. Readmission rates are increasingly used as a surgical quality metric. White blood cell count is a crude surrogate for physiologic processes which may reflect postoperative complications leading to readmission. Objective: We assessed the association between final white blood cell count at discharge and risk of readmission following radical cystectomy. Methods: Records on 477 patients undergoing radical cystectomy from 2006-2013 were reviewed. Final white blood cell count was defined as the last documented value during index admission. Univariate analysis was performed using Fisher's exact, Wilcoxon rank sum test, and Spearman's coefficient tests where appropriate. Multivariable logistic regression models were used to test the associations between final white blood cell count and readmission. Results: 34% of patients were readmitted within 90 days of surgery. Amongst this cohort, a cutoff final white blood cell count of 9000/mm 3 was identified, with a significantly higher proportion of patients with values >9000/mm 3 experiencing readmission than those with values≤9000/mm 3 (42% vs 28%, p  = 0.004). Other perioperative variables associated with an increased readmission rate included initial hospital length of stay≤10 days, and receipt of a continent diversion. Following adjustment, final white blood cell count >9000/mm 3 was associated with increased risk of readmission (OR 2.09, 95% CI 1.23-3.53, p  = 0.006). Conclusions: Final white blood cell count is associated with hospital readmission following radical cystectomy. This metric may provide important guidance in discharge algorithms.

To evaluate quality of life (QoL) and overall survival after radical cystectomy with cutaneous ureterostomies for locally advanced bladder cancer in elderly patients with high surgical risk. Fifty eight patients older than 74 years (mean age 80,6±4,3) with locally advanced bladder cancer (group A), underwent radical cystectomy and ureterocutaneous diversion. Patients completed the EORTC QLQC30 before and six months after surgery to assess functional, clinical and QoL outcomes. The same evaluation was carried out in a control group (group B) of 29 patients (mean age 82,3±3,8 years), who had refused cystectomy. Questionnaires were also administered to patients of both groups who survived at least 20 months and 5 years. All patients presented with an ASA score ≥3. Mean hospital stay was 15.1 days (±4.8) in group A and 23.5 days (±4.1) in Group B. No intraoperative complications occurred in group A. Postoperative overall survival evaluated within 6 months in group A was 97% versus 79% in group B (pbladder cancer and high operative risk. Comparison between two groups showed a statistically significant difference for almost all the Qol related parameters and for short and medium term overall survival. Copyright © 2012 AEC.

2018-02-01

Robot-assisted radical cystectomy (RARC) is increasing annually for treatment of bladder cancer. The objective of this meta-analysis was to compare the safety and efficacy of RARC and open radical cystectomy (ORC) for bladder cancer. Our meta-analysis searches were conducted using PubMed, Web of Science, and Cochrane Library databases to identify randomized controlled trials (RCT) assessing the two techniques. Four RCT studies were identified, including 239 cases. Our studies indicated that RARC was associated with longer operative time (WMD: 69.69, 95% CI:17.25 to122.12; P= 0.009), lower estimated blood loss (WMD: -299.83, 95% CI:-414.66to -184.99; P<0.00001). The two groups had no significant difference in overall perioperative complications, length of hospital stay, lymph node yield and positive surgical margins. RARC is mini-invasive alternative to ORC for bladder cancer. The advantage of RARC was reduced estimated blood loss. More studies are needed to compare the two techniques.

Hwanik Kim

Full Text Available PURPOSE: The objective of the present study was to conduct a systematic review and meta-analysis of published literature to appraise the prognostic value of lymphovascular invasion (LVI in radical cystectomy specimens. MATERIALS AND METHODS: Following the PRISMA statement, PubMed, Cochrane Library, and SCOPUS database were searched from the respective dates of inception until June 2013. RESULTS: A total of 21 articles met the eligibility criteria for this systematic review, which included a total of 12,527 patients ranging from 57 to 4,257 per study. LVI was detected in 34.6% in radical cystectomy specimens. LVI was associated with higher pathological T stage and tumor grade, as well as lymph node metastasis. The pooled hazard ratio (HR was statistically significant for recurrence-free survival (pooled HR, 1.61; 95% confidence interval [CI], 1.26-2.06, cancer-specific survival (pooled HR, 1.67; 95% CI, 1.38-2.01, and overall survival (pooled HR, 1.67; 95% CI, 1.38-2.01, despite the heterogeneity among included studies. On sensitivity analysis, the pooled HRs and 95% CIs were not significantly altered when any one study was omitted. The funnel plot for overall survival demonstrated a certain degree of asymmetry, which showed slight publication bias. CONCLUSIONS: This meta-analysis indicates that LVI is significantly associated with poor outcome in patients with bladder cancer who underwent radical cystectomy. Adequately designed prospective studies are required to provide the precise prognostic significance of LVI in bladder cancer.

Robotic Assisted Radical Cystectomy with Extracorporeal Urinary Diversion Does Not Show a Benefit over Open Radical Cystectomy: A Systematic Review and Meta-Analysis of Randomised Controlled Trials.

Full Text Available The number of robotic assisted radical cystectomy (RARC procedures is increasing despite the lack of Level I evidence showing any advantages over open radical cystectomy (ORC. However, several systematic reviews with meta-analyses including non-randomised studies, suggest an overall benefit for RARC compared to ORC. We performed a systematic review with meta-analysis of randomised controlled trials (RCTs to evaluate the perioperative morbidity and efficacy of RARC compared to ORC in patients with bladder cancer.Literature searches of Medline/Pubmed, Embase, Web of Science and clinicaltrials.gov databases up to 10th March 2016 were performed. The inclusion criteria for eligible studies were RCTs which compared perioperative outcomes of ORC and RARC for bladder cancer. Primary objective was perioperative and histopathological outcomes of RARC versus ORC while the secondary objective was quality of life assessment (QoL, oncological outcomes and cost analysis.Four RCTs (from 5 articles met the inclusion criteria, with a total of 239 patients all with extracorporeal urinary diversion. Patient demographics and clinical characteristics of RARC and ORC patients were evenly matched. There was no significant difference between groups in perioperative morbidity, length of stay, positive surgical margin, lymph node yield and positive lymph node status. RARC group had significantly lower estimated blood loss (p<0.001 and wound complications (p = 0.03 but required significantly longer operating time (p<0.001. QoL was not measured uniformly across trials and cost analysis was reported in one RCTs. A test for heterogeneity did highlight differences across operating time of trials suggesting that surgeon experience may influence outcomes.This study does not provide evidence to support a benefit for RARC compared to ORC. These results may not have inference for RARC with intracorporeal urinary diversion. Well-designed trials with appropriate endpoints conducted

The Ileal W-Shaped Neo bladder Following Radical Cystectomy for Carcinoma of the Urinary Bladder: Experience and Results of 50 Cases

The optimal urinary bladder substitute for patients undergoing radical cystectomy is still controversial. The ideal reservoir should provide a large storage capacity at low pressure achieving effective continence with less frequency and minimal renal reflux. In this study we present our experience with W-shaped ileal neo bladder following radical cystectomy. Material and Methods: Between April 1995 and September 1999, a total of 50 male patients underwent lower urinary tract reconstruction following radical cysto prostatectomy by means of ileal W-shaped neo bladder. All patients had invasive bladder cancer proved by preoperative cystoscopy. Their mean age was 45.5 years. The median neo bladder pouch capacity was 420 ml; daytime continence rate was 89.4%, while nighttime continence was noticed in 53.3% of cases. The uretero intestinal anastomoses were performed employing Le Duc technique in all patients. Renal units remained normal in 25 out of 30 evaluated patients. Dilatation of the pelvicalyceal system and the ureter, either unilateral or bilateral occurred in 5/30 of patients (16.6%). These were due to stricture at the urethro or uretero-pouch anastomosis that needed transurethral urethrotomy or revision of the anastomosis; however, renal functions were maintained in all patients. There were three postoperative mortalities (6%) and the early postoperative complications included urinary leakage (6%), prolonged ileus (10%) and deep venous thrombosis (4%). Late complications related to the neo bladder were acceptable including metabolic acidosis (2%). The ileal W-shaped neo bladder is a good choice for male patients after radical cystectomy, provided that there is no evidence of prostatic or urethral tumor invasion

2004-01-01

Evaluation of the diagnostic, prognostic and possible therapeutic role of extended lymphadenectomy to lower para-aortic area in operable bladder cancer patients. Patients and Methods: One hundred and nine patients were subjected to the procedure in the National Cancer Institute, Cairo University, and in Minea Oncology Center, Ministry of Health by the same group of surgeons, during the period from September 2000 to March 2003. The lymph nodes dissected were labeled to the following groups: perivesical, lymph node of Cloquet, external iliac, internal iliac and obturator, common iliac and paraortic groups both right and left. These nodes were subjected with the primary tumor to serial sectioning for histopathologic examination. Preoperatively, all patients were subjected to routine laboratory investigations. [n addition to cystoscopy, biopsy and histopathologic examination, bone scan, chest X-Ray and computerized tomography with l. V. contrast examination for the abdomen and pelvis were done for clinical staging of the disease. 34.4% of the node positive patients have been found to harbor the disease in the para-aortic lymph nodes above the common iliac bifurcation. Obturator, external iliac, internal iliac, para-aortic, common iliac, perivesical and lymph node of Cloquet are the higher incidence groups of positive lymph nodes sequentially. The clinical and c.T. staging are inaccurate methods of diagnosis due to high overall error in up to 70.6% of patients. There is no higher incidence of morbidity, mortality, operative time or intraoperative blood loss related to the addition of lower para-aortic dissection to the routine radical cystectomy. Extension of lymphadenectomy to include the lower para-aortic area in addition to the standard pelvic lymphadenectomy during radical cystectomy for bladder cancer is a more accurate technique for diagnosis and staging of bladder cancer patients and it may help in determining the benefit of adjuvant chemotherapy ± radiotherapy

2017-01-01

BACKGROUND: Despite smoking and risky alcohol drinking being modifiable risk factors for cancer as well as postoperative complications, perioperative cessation counselling is often ignored. Little is known about how cancer patients experience smoking and alcohol interventions in relation to surgery....... Therefore the aim of this study was to explore how bladder cancer patients experience a perioperative smoking and alcohol cessation intervention in relation to radical cystectomy. METHODS: A qualitative study was conducted in two urology out-patient clinics. We conducted semi-structured in-depth interviews...... with 11 purposively sampled persons who had received the smoking and alcohol cessation intervention. The analysis followed the steps contained in the thematic network analysis. RESULTS: Two global themes emerged: "smoking and alcohol cessation was experienced as an integral part of bladder cancer surgery...

Integrated preoperative irradiation and radical cystectomy

Thirty patients with stage B 2 -C-D 1 and/or grade III-IV transitional cell carcinoma of the bladder were entered into a pilot study of integrated surgery and radiotherapy. Staging laparotomy with formation of an ileal loop preceded the delivery of 4000 to 5000 rad in 4 to 5 weeks to the pelvis; cystectomy was accomplished in 26 patients 4 to 8 weeks after completion of irradiation. The program was accomplished without undue difficulty and resulted in a lowering of the clinical stage in 22 of 26 patients; no residual invasive cancer was seen histologically in 8 patients. Although it was formidable, the morbidity rate was not significantly different than it was after cystectomy without preoperative irradiation. The short term survival rate, in conjunction with an analysis of sites of failure, suggests that a prospective study be accomplished to document the validity of this therapeutic approach to bladder cancer; patient selection, surgical technique, and time-dose-volume radiation factors should also be considered

The objective of our study was to analyze the diagnostic performance of (18) F-fluorodeoxyglucose positron emission tomography-computed tomography for lymph node staging in patients with bladder cancer before radical cystectomy and to compare it with that of computed tomography. A total of 52 patients operated on between 2005 and 2010 were prospectively included in this prospective, mono-institutional, open, non-randomized pilot study. Patients who had received neoadjuvant chemotherapy or radiotherapy were excluded. (18) F-fluorodeoxyglucose positron emission tomography-computed tomography in addition to computed tomography was carried out for lymph node staging of bladder cancer before radical cystectomy. Lymph node dissection during radical cystectomy was carried out. Findings from (18) F-fluorodeoxyglucose positron emission tomography-computed tomography and computed tomography were compared with the results of definitive histological examination of the lymph node dissection. The diagnostic performance of the two imaging modalities was assessed and compared. The mean number of lymph nodes removed during lymph node dissection was 16.5 ± 10.9. Lymph node metastasis was confirmed on histological examination in 22 cases (42.3%). This had been suspected in five cases (9.6%) on computed tomography and in 12 cases (23.1%) on (18) F-fluorodeoxyglucose positron emission tomography-computed tomography. Sensitivity, specificity, positive predictive value, negative predictive value, relative risk and accuracy were 9.1%, 90%, 40%, 57.4%, 0.91 and 55.7%, respectively, for computed tomography, and 36.4%, 86.7%, 66.7%, 65%, 2.72, 65.4%, respectively, for (18) F-fluorodeoxyglucose positron emission tomography-computed tomography. (18) F-fluorodeoxyglucose positron emission tomography-computed tomography is more reliable than computed tomography for preoperative lymph node staging in patients with invasive bladder carcinoma undergoing radical cystectomy. © 2012 The Japanese

Prognostic features for quality of life after radical cystectomy and orthotopic neobladder

Alexander Kretschmer

Full Text Available ABSTRACT Purpose: To analyse prognostic features on quality of life (QoL following radical cystectomy and urinary diversion via orthotopic neobladder in a single-centre patient cohort. Materials and Methods: Postoperative QoL of 152 patients was assessed retrospectively using the validated QLQ-C30 questionnaire. Potential associations of patient's quality of life including pre-and intraoperative characteristics, surgeon experience, postoperative time course, adjuvant therapies, and functional outcome were defined a priori and evaluated. Mann-Whitney-U-, Kruskal-Wallis-, Spearman correlation and post hoc-testing were used. A multivariate analysis using a multiple logistic regression model was performed. A p value 100 previous cystectomies, p=0.007, and nerve-sparing surgery (p=0.001. Patients who underwent secondary chemotherapy or radiotherapy had significant lower QLQ-C30 scores (p=0.04, p=0.02 respectively. Patients who were asymptomatic had a significantly higher quality of life (p<0.001. A significant impact of severity of incontinence based on ICIQ-SF score (p<0.001 and daily pad usage (p<0.001, existence of daytime incontinence (p<0.001, existence of urgency symptoms (p=0.007, and IIEF-5 score (p<0.001 could be observed. In multivariate analysis, independent prognostic relevance could be confirmed for preoperative ECOG performance status of 0 (p=0.020 vs. ECOG 1, p=0.047 vs. ECOG 2, experience of the respective surgeon (≥100 vs. <100 previous cystectomies, p=0.021, and daytime continence (p=0.032. Conclusion: In the present study, we report health-related QoL outcomes in a contemporary patient cohort and confirm preoperative ECOG status, surgeon experience and daytime incontinence as independent prognostic features for a good postoperative QoL.

To describe the surgical technique and report early outcomes of transurethral assisted laparoendoscopic single-site (LESS) radical prostatectomy (RP) and LESS radical cystectomy (RC) in a single institution. Between December 2014 and March 2016, a total of 114 LESS RPs and RCs were performed, comprising 68 LESS RPs, 38 LESS RCs with cutaneous ureterostomy (CU) and eight LESS RCs with orthotopic ileal neobladder (OIN). Access was achieved via a single-port, with four channels placed through a transumblical incision. After the apex of prostate was separated from the urethra, a self-developed port ('Zhu's port') was inserted through the urethra to facilitate resection of prostate and urethrovesical anastomosis. The peri-operative and postoperative data were collected and analysed retrospectively. Patients were followed up postoperatively for evidence of long-term side effects. All the procedures were completed successfully. No conversion to conventional laparoscopic surgery was necessary. For LESS RP, the average operating time was 152 min. Estimated blood loss was 117 mL. The mean hospital stay was 16.4 days after surgery. For LESS RC with CU and LESS RC with OIN, the mean operating times were 215 and 328 min, mean estimated blood loss was 175 and 252 mL, and mean hospital stay was 9.4 and 18.2 days, respectively. Six patients required blood transfusion (5.26%). Intra-operative complications occurred in two patients (1.75%), and postoperative complications in nine (7.89%). Fourteen out of 68 (20.6%) patients who underwent LESS RP had positive surgical margins. Follow-up ranged from 10 to 30.6 months. In the prostate cancer cases, good urinary control was observed in 35.3%, 97.1% and 100% of patients at 1, 6 and 12 months after the operation, respectively, while biochemical recurrence was observed in 11.8% patients. In the bladder cancer cases, two patients had local recurrence and two patients had distant metastasis. Our results showed that LESS RP and LESS RC

The last decade has witnessed an increasing trend towards minimally invasive management of prostate cancer, including laparoscopic and, more recently, robot-assisted laparoscopic prostatectomy. Several different laparoscopic approaches have been continuously developed during the last 5 years and it is still unclear which technique yields the best outcome. We present our current technique of robot-assisted laparoscopic radical prostatectomy. The technique described has evolved during the course of >400 robotic prostatectomies performed by the robotic team since the robot-assisted laparoscopic radical prostatectomy program was introduced at Karolinska University Hospital in January 2002. Our procedure comprises several modifications of previously reported ones, and we utilize fewer robotic instruments to reduce costs. An extended posterior dissection is performed to aid in the bladder neck-sparing dissection. In nerve-sparing procedures the vesicles are divided to avoid damage to the erectile nerves. In order to preserve the apical anatomy the dorsal venous complex is incised sharply and is first over-sewn after the apical dissection is completed. Our technique enables a more fluent dissection than previously described robotic techniques. Minimizing changes of instruments and the camera not only cuts costs but also reduces inefficient operating maneuvers, such as switching between 30 degrees and 0 degrees lenses during the procedure. We present a technique which in our hands has achieved excellent functional and oncological results.

Veno-occlusive dysfunction (formerly called "venous leakage") is a clinical-radiographic manifestation of a multi-aetiology syndrome, the pathogenesis of which is to be sought in intrinsic damage to the erectile tissue. It has been attributed to psycho-neurogenic, neurovascular and local--physical factors. The unsatisfactory results of the various surgical techniques proposed (venous ligatures, crural plication, corporopexy) can be explained by the formation of vicarious venous circles, a phenomenon which occurs regardless of the type of procedure adopted and which is the direct consequence of the alteration of the occlusive mechanisms intrinsic to the erectile tissue. At the Urological Institute of the University of Milan, a study has been carried out with the aim of experimentally assessing these aetiopathogenetic hypotheses. 48 sexually potent patients were selected from those scheduled for extensive surgical procedures on account of malignant pathologies of the pelvic cavity (urethro-prostato-cystectomy, radical prostatectomy). The protocol included a series of examinations before and after the operation (at three months): computerised recording of nocturnal erections (NPT test, three consecutive nights), dynamic penile Doppler velocimetry, dynamic cavernosometry/graphy, examination of bulbocavernosus reflex. The goal of the study was to evaluate the haemodynamic consequences of the massive venous ligatures effected during these operations (periprostatic plexus, deep dorsal vein, spongio-cavernous connections). There were 28 cases of radical prostatectomy and 20 cases of radical urethro-prostato-cystectomy. Among the cases of radical prostatectomy, the extrafascial retropubic technique was used for 14 patients, the monolateral nerve-sparing procedure was applied for 10 patients (stage B1) and the transperineal approach was used for 4 patients (the most recent).(ABSTRACT TRUNCATED AT 250 WORDS)

Full Text Available Abstract Background The objective of this study was to develop a modified retroperitoneal laparoscopic nephrectomy and compare its results with the previous technique. Methods One hundred retroperitoneal laparoscopic nephrectomies were performed from February 2007 to October 2011. The previous technique was performed in 60 cases (Group 1. The modified technique (n = 40 included fast access to the renal pedicle according to several anatomic landmarks and early ligation of renal vessels (Group 2. The mean operation time, mean blood loss, duration of hospital stay conversion rate and complication rate were compared between the groups. Results No significant differences were detected regarding mean patient age, mean body mass index, and tumor size between the two groups (P >0.05. The mean operation time was 59.5 ± 20.0 and 39.5 ± 17.5 minutes, respectively, in Groups 1 and 2 (P P P >0.05. Conclusions Early ligature using fast access to the renal vessels during retroperitoneal laparoscopic radical nephrectomy contributed to less operation time and intraoperative blood loss compared with the previous technique. In addition, the modified technique permits the procedure to be performed following the principles of open radical nephrectomy.

Married (vs. unmarried) individuals have improved health status and longer life expectancies in a variety of benign and malignant disease states, including prostate, breast, head/neck, and lung cancers. We sought to evaluate a cohort of patients undergoing cystectomy for bladder cancer to evaluate the impact of marital status on demographic, peri-operative, and pathological outcomes in order to better understand the factors which may contribute to the survival differences observed. Two-hundred and two patients underwent radical cystectomy and urinary diversion for bladder cancer. Patients were categorized based on marital status as either married or unmarried (widowed, divorced, never married). Correlations were made to demographic factors (age, race, gender, BMI, tobacco use, alcohol use), perioperative factors (pre-op renal function (creatinine), hematocrit, EBL, hospital stay, choice of diversion), and pathological outcomes (organ-confined status, LN positivity). Of the 202 patients, 74% were married. Married individuals (vs. unmarried) were more often male (84 vs. 62%) and had a higher BMI (28.1 vs. 25.9). Married persons had a significantly lower pre-op creatinine (1.1 vs. 1.4) and higher hematocrit (39 vs. 34). Hospital stay was shorter in married patients by a mean of 1.6 days. Regarding operative pathology, married patients had a higher rate of organ-confined disease (59 vs. 47%) (P = 0.05, 0.08 on multivariate) and trended towards a lower rate of LN positivity (15 vs. 21%; P = 0.10, 0.12 multivariate). In patients undergoing cystectomy for bladder cancer, married individuals appear to have improved pre-operative laboratory variables, shorter hospitalization, and improved pathological outcomes versus unmarried patients in our case series. These findings may support the evidence (observed in other tumor types and other disease states) that married persons present earlier than unmarried individuals, and this may help explain the improved survival outcomes

We describe a novel technique of partial cystectomy that allows accurate identification of tumor margins while minimizing damage to the rest of the bladder. Methods: During the study period, 30 patients underwent partial cystectomy for invasive high-grade cancer. In 19 patients, the traditional method of tumor identification was used, ie, identifying the tumor by palpation and cystotomy. In eleven patients, after mobilization of the bladder, flexible cystoscopy was done and the light of the cystoscope was pointed toward one edge of the planned resected ellipse around the tumor, thus avoiding cystotomy. Results: Patients who underwent partial cystectomy using the novel method were similar in all characteristics to patients operated on using the traditional technique except for tumor diameter which was significantly larger in patients operated on using the novel method (4.3±1.5 cm versus 3.11±1.18 cm, P=0.032. Complications were rare in both types of surgery. The 5-year local recurrence-free survival was marginally superior using the novel method (0.8 versus 0.426, P=0.088. Overall, disease-specific and disease-free survival rates were similar. Conclusion: The use of a flexible cystoscope during partial cystectomy is a simple, low-cost maneuver that assists in planning the bladder incision and minimizes injury to the remaining bladder by avoiding the midline cystotomy. Initial oncological results show a trend toward a lower rate of local

We reviewed the results of infiltrating bladder cancer treated by radical cystectomy to evaluate cancer treated by radical cystectomy to evaluate survival. Between January 1989 and December 1992, a total of 58 consecutive cystectomies or anterior pelvic exenterations performed on 48 men and 10 women (mean age 63.2 years) in our department were retrospectively evaluated. Four patients were lost to follow-up and the mean follow-up was 72 months. Pathologic staging was as follows: stage pTO,A,1: 13.5%, stage pT2: 17.5%, stage pT3a: 12%, stage pT3b: stage pT4: 21%. The year probability of the overall survival was 60% for pT2-p T3a patients, 15% for pT3b patients, and 9% for pT4 patients, respectively. Overall, 53.5% of patients died of cancer, 7.5% of intercurrent disease, and 39% were alive. The cancer related death rate was 12% for pT2-pT3a patients, and 82% for pT3b-pT4 patients. The 5- year probability of specific survival was 80% for pT2-pT3a patients, 15% for pT3b patients and 9% for pT4 patients, respectively. Infiltrating bladder cancer still has a high mortality rate. Radical cystectomy may be considered to be a curative procedure for stages pT2 and pT3a. Adjuvant chemotherapy and/or radiotherapy seem necessary at stages pT3 and pT4. Preoperative criteria need to be better defined to reduce understanding. (authors)

We present an approach to laparoscopic radical nephrectomy and intact specimen extraction, which incorporates hand assisted and standard laparoscopic techniques. A refined approach to laparoscopic radical nephrectomy is described and our experience is reviewed. A low, muscle splitting Gibson incision is made just lateral to the rectus muscle and the hand port is inserted. A trocar is placed through the hand port and pneumoperitoneum is established. With the laparoscope in the hand port trocar 2 additional trocars are placed under direct vision. The laparoscope is then repositioned through the middle trocar and standard laparoscopic instruments are used through the other 2 trocars including the one in the hand port. If at any time during the procedure the surgeon believes the hand would be useful or needed, the trocar is removed from the hand port and the hand is inserted. This approach has been applied to 7 patients. Mean estimated blood loss was 200 cc (range 50 to 300) and mean operative time was 276.7 minutes (range 247 to 360). Mean specimen weight was 767 gm. (range 538 to 1,170). Pathologically 6 specimens were renal cell carcinoma (grades 2 to 4) and 1 was oncocytoma. Mean length of hospital stay was 3.71 days (range 2 to 7). There were no major complications. We believe that this approach enables the surgeon to incorporate the advantages of the hand assisted and standard laparoscopic approaches.

Full Text Available OBJECTIVE: To analyze the results of the treatment of transitional cell carcinoma (TCC of the bladder with radical cystectomy and determine which prognostic factors can be utilized as disease-free survival and cancer-specific survival independent variables. MATERIALS AND METHODS: Medical records of 113 patients submitted to radical cystectomy and bilateral iliac lymphadenectomy between 1993 and 2005 were reviewed. The risk factors analyzed were age, sex, pathological stage, tumor grade, presence of carcinoma in situ and the presence of lymph nodes involvement. RESULTS: After a mean follow-up of 31.7 ? 28.5 months, 46 patients (40.7% presented recurrence and 24 patients (21.2% died due to cancer. Only pathological stage and the lymph nodes involvement became independent variables for recurrence and survival. Patients with T4 stage presented 9.6 times the risk of recurrence of the disease when compared with stage T0 patients (p = 0.010 and the patients with lymph node involvement presented 2.5 times the risk of recurrence (p = 0.047 and 3.1 times the risk of death (p = 0.022 when compared to patients without lymph nodes involvement. CONCLUSIONS: Pathological stage and the involvement of lymph nodes represented more important prognostic variables, and in the presence of advanced stage tumors (T3/T4 and involvement of lymph nodes, the institution of adjuvant treatment should be considered.

Full Text Available OBJECTIVE: We studied the long-term outcome of radical cystectomy for transitional cell carcinoma and evaluated prognostic factors for disease specific survival. MATERIALS AND METHODS: A retrospective review was carried out for all cystectomies performed for transitional cell carcinoma between 1989 and 2002. Disease specific survival was correlated to patient, pathological and operative factors as well as to adjuvant therapy. RESULTS: Of the 133 cystectomies included, 100 were male and 33 were female patients. The median age was 69 years (range 43 to 86. The median follow up was 20 months (range 0 to 158. With univariate analysis, pT stage, N stage, lymph node density, carcinoma in-situ, surgical margin and post-operative radiotherapy to distant metastasis were predictive of disease specific survival. On the other hand, with multivariate analysis, only pT stage, lymph node density and post-operative radiotherapy to distant metastasis were predictive of disease specific survival. Within the group of node positive disease, lymph node density also predicted disease specific survival with both univariate and multivariate analyses. Patients with lymph node density 20% or below showed better disease specific survival. CONCLUSIONS: pT stage and lymph node density were found to be the most important predictive factors for disease specific survival after cystectomy in the Asian population.

We aimed to develop a structured scoring tool: cystectomy assessment and surgical evaluation (CASE) that objectively measures and quantifies performance during robot-assisted radical cystectomy (RARC) for men. A multinational 10-surgeon expert panel collaborated towards development and validation of CASE. The critical steps of RARC in men were deconstructed into nine key domains, each assessed by five anchors. Content validation was done utilizing the Delphi methodology. Each anchor was assessed in terms of context, score concordance, and clarity. The content validity index (CVI) was calculated for each aspect. A CVI ≥ 0.75 represented consensus, and this statement was removed from the next round. This process was repeated until consensus was achieved for all statements. CASE was used to assess de-identified videos of RARC to determine reliability and construct validity. Linearly weighted percent agreement was used to assess inter-rater reliability (IRR). A logit model for odds ratio (OR) was used to assess construct validation. The expert panel reached consensus on CASE after four rounds. The final eight domains of the CASE included: pelvic lymph node dissection, development of the peri-ureteral space, lateral pelvic space, anterior rectal space, control of the vascular pedicle, anterior vesical space, control of the dorsal venous complex, and apical dissection. IRR > 0.6 was achieved for all eight domains. Experts outperformed trainees across all domains. We developed and validated a reliable structured, procedure-specific tool for objective evaluation of surgical performance during RARC. CASE may help differentiate novice from expert performances.

Purpose: In patients with muscle-invasive bladder cancer, local-regional failure (LF) has been reported to occur in up to 20% of patients following radical cystectomy. The goals of this study were to describe patterns of LF, as well as assess factors associated with LF in a cohort of patients with pT3-4 bladder cancer. This information may have implications towards the use of adjuvant radiation therapy. Methods and Materials: Patients with pathologic T3-4 N0-1 bladder cancer were examined from an institutional radical cystectomy database. Preoperative demographics and pathologic characteristics were examined. Outcomes included overall survival and LF. Local-regional failures were defined using follow-up imaging reports and scans, and the locations of LF were characterized. Variables were tested by univariate and multivariate analysis for association with LF and overall survival. Results: A total of 334 patients had pT3-4 and N0-1 disease after radical cystectomy and bilateral pelvic lymph node dissection. Of these, 46% received perioperative chemotherapy. The median age was 71 years old, and median follow-up was 11 months. On univariate analysis, margin status, pT stage, and pN stage, were all associated with LF (P<.05), however, on multivariate analysis, only pT and pN stages were significantly associated with LF (P<.05). Three strata of risk were defined, including low-risk patients with pT3N0 disease, intermediate-risk patients with pT3N1 or pT4N0 disease, and high-risk patients with pT4N1 disease, who had a 2-year incidence of LF of 12%, 33%, and 72%, respectively. The most common sites of pelvic relapse included the external and internal iliac lymph nodes (LNs) and obturator LN regions. Notably, 34% of patients with LF had local-regional only disease at the time of recurrence. Conclusions: Patients with pT4 or N1 disease have a 2-year risk of LF that exceeds 30%. These patients may be the most likely to benefit from local adjuvant therapies.

To revaluate ileocolonic pouch for ortho-topic neobladder reconstruction, a cohort of patients with bladder cancer was selected to undergo radical cystectomy and modified Le Bag pouch. Evaluation concentrates on continence and associated morbidity observed on close follow-up. Patients and Methods: A total of 37 patients including 16 females with T2 3 bladder cancer (19 transitional, 15 : squamous and 3 adenocarcinoma) were treated by radical cystectomy and totally detubularized ileocolic neobladder. Post operative morbidity, continence and urodynamic studies were evaluated. Mean time to have full daytime continence was tested against age, gender, postoperative complications, technique of pouch creation either stapler or hand suture and adjuvant irradiation. Results: Cystometry 12 months post surgery showed 493 ml median capacity with basal and maximum reservoir median pressures of 16 and 38 cm H 2 O respectively. Uro-flowmetry had maximum voiding volume of 370ml, voiding time 45s and maximum flow rate of 11.6ml/s. Within the first 2 months post operative 44% were continent by day, 33% by night and 67% had stress incontinence. By 12 months post surgery 89% were continent by day, 73% by night and 27% had stress incontinence. Two years post surgery 94% were continent by day and 81 % had complete day and night control of uri-ne. Urinary leakage was the most frequent early complication (10.8%). Late complications were urinary tract infection (13.5%), metabolic acidosis (13.5%) and reflux (10.8%). Pouch over distension (5.4%) was consistent with bladder neck obstruction. Patient's gender and postoperative morbidity were statistically significant factors to increase the mean time to continence; whereas, age, use of stapler and adjuvant radiotherapy had no significant effect. Conclusion: Modified Le Bag pouch is a simple technique with adequate pouch capacity that offers excellent slowly progressing continence rates with minor morbidity rate. Post operative morbidity and

Full Text Available Background : Over the last two decades, numerous studies have indicated the feasibility of minimally invasive surgery for early cervical cancer without compromising the oncological outcome. Objective : Systematic literature review and meta analysis aimed at evaluating the outcome of laparoscopic and robotic radical hysterectomy (LRH and RRH and comparing the results with abdominal radical hysterectomy (ARH. Search Strategy : Medline, PubMed, Embase, Cochrane library and Reference lists were searched for articles published until January 31 st 2011, using the terms radical hysterectomy, laparoscopic radical hysterectomy, robotic radical hysterectomy, surgical treatment of cervical cancer and complications of radical hysterectomy. Selection Criteria : Studies that reported outcome measures of radical hysterectomy by open method, laparoscopic and robotic methods were selected. Data collection and analysis: Two independent reviewers selected studies, abstracted and tabulated the data and pooled estimates were obtained on the surgical and oncological outcomes. Results : Mean sample size, age and body mass index across the three types of RH studies were similar. Mean operation time across the three types of RH studies was comparable. Mean blood loss and transfusion rate are significantly higher in ARH compared to both LRH and RRH. Duration of stay in hospital for RRH was significantly less than the other two methods. The mean number of lymph nodes obtained, nodal metastasis and positive margins across the three types of RH studies were similar. Post operative infectious morbidity was significantly higher among patients who underwent ARH compared to the other two methods and a higher rate of cystotomy in LRH. Conclusions : Minimally invasive surgery especially robotic radical hysterectomy may be a better and safe option for surgical treatment of cervical cancer. The laparoscopic method is not free from complications. However, experience of surgeon may

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.

Purpose: To perform a comprehensive comparison of overall survival (OS), disease-specific survival (DSS), progression-free survival (PFS), and treatment-related complications between radical cystectomy (RC) and combined modality treatment (CMT—radiation therapy, concurrent chemotherapy, and maximal transurethral resection of bladder tumor) in the setting of muscle-invasive bladder cancer. Methods and Materials: We searched 7 databases (PubMed, Scopus, EMBASE, Proquest, CINAHL, and (ClinicalTrials.gov)) for randomized, controlled trials and prospective and retrospective studies directly comparing RC with CMT from database inception to March 2016. We conducted meta-analyses evaluating OS, DSS, and PFS with hazard ratios (HRs) and 95% confidence intervals (CIs). Results: Nineteen studies evaluating 12,380 subjects were selected. For the 8 studies encompassing 9554 subjects eligible for meta-analyses, we found no difference in OS at 5 years (HR 0.96, favoring CMT, 95% CI 0.72-1.29; P=.778) or 10 years (HR 1.02, favoring cystectomy, 95% CI 0.73-1.42; P=.905). No difference was observed in DSS at 5 years (HR 0.83, favoring radiation, 95% CI 0.54-1.28; P=.390) or 10 years (HR 1.17, favoring cystectomy, 95% CI 0.89-1.55; P=.264), or PFS at 10 years (HR 0.85, favoring CMT, 95% CI 0.43-1.67; P=.639). The cystectomy arms had higher rates of early major complications, whereas rates of minor complications were similar between the 2 treatments. Conclusion: Current meta-analysis reveals no differences in OS, DSS, or PFS between RC and CMT. Further randomized, controlled trials are necessary to identify the optimal treatment for specific patients.

Purpose: To perform a comprehensive comparison of overall survival (OS), disease-specific survival (DSS), progression-free survival (PFS), and treatment-related complications between radical cystectomy (RC) and combined modality treatment (CMT—radiation therapy, concurrent chemotherapy, and maximal transurethral resection of bladder tumor) in the setting of muscle-invasive bladder cancer. Methods and Materials: We searched 7 databases (PubMed, Scopus, EMBASE, Proquest, CINAHL, and (ClinicalTrials.gov)) for randomized, controlled trials and prospective and retrospective studies directly comparing RC with CMT from database inception to March 2016. We conducted meta-analyses evaluating OS, DSS, and PFS with hazard ratios (HRs) and 95% confidence intervals (CIs). Results: Nineteen studies evaluating 12,380 subjects were selected. For the 8 studies encompassing 9554 subjects eligible for meta-analyses, we found no difference in OS at 5 years (HR 0.96, favoring CMT, 95% CI 0.72-1.29; P=.778) or 10 years (HR 1.02, favoring cystectomy, 95% CI 0.73-1.42; P=.905). No difference was observed in DSS at 5 years (HR 0.83, favoring radiation, 95% CI 0.54-1.28; P=.390) or 10 years (HR 1.17, favoring cystectomy, 95% CI 0.89-1.55; P=.264), or PFS at 10 years (HR 0.85, favoring CMT, 95% CI 0.43-1.67; P=.639). The cystectomy arms had higher rates of early major complications, whereas rates of minor complications were similar between the 2 treatments. Conclusion: Current meta-analysis reveals no differences in OS, DSS, or PFS between RC and CMT. Further randomized, controlled trials are necessary to identify the optimal treatment for specific patients.

Urinary tract infection (UTI) is one of the most common complications after radical cystectomy and orthotopic neobladder reconstruction. This study investigated the incidence and implicated pathogen of febrile UTI after ileal neobladder reconstruction and identify clinical and urodynamic parameters associated with febrile UTI. From January 2001 to May 2015, 236 patients who underwent radical cystectomy and ileal neobladder were included in this study. Fifty-five episodes of febrile UTI were identified in 46 patients (19.4%). The probability of febrile UTI was 17.6% and 19.8% at 6 months and 24 months after surgery, respectively. While, Escherichia coli was the most common implicated pathogen (22/55, 40.0%), Enterococcus spp. were the most common pathogen during the first month after surgery (18/33, 54.5%). In multivariate logistic regression analysis, ureteral stricture was an independent risk factor associated with febrile UTI (OR 5.93, P = 0.023). However, ureteral stricture accounted for only 6 episodes (10.9%, 6/55) of febrile UTI. Most episodes of febrile UTI occurred within 6 months after surgery. Thus, to identify risk factors associated with febrile UTI in the initial postoperative period, we assessed videourodynamics within 6 months after surgery in 38 patients. On videourodyamic examination, vesicoureteral reflux (VUR) was identified in 16 patients (42.1%). The rate of VUR presence in patients who had febrile UTI was not significantly different from those in patients without febrile UTI (50% vs. 39.3%, P = 0.556). Patients with febrile UTI had significantly larger residual urine volume (212.0 ± 193.7 vs. 90.5 ± 148.2, P = 0.048) than those without. E. coli and Enterococcus spp. are common pathogens and ureteral stricture and residual urine are risk factors for UTI after ileal neobladder reconstruction.

Full Text Available Objective: To compare pathological and oncological outcomes between robotic-assisted laparoscopic radical prostatectomy (RaLRP and laparoscopic radical prostatectomy (LRP among high-risk prostate cancer patient in a tertiary center in Taiwan. Materials and methods: From November 2003 to October 2013, 129 high-risk prostate cancer patients receiving minimally-invasive radical prostatectomy were included. The Kaplan–Meier analysis was used for measuring biochemical recurrence-free survival (BFS. Multivariate logistic regression models and Cox proportional hazards regression models were used to determine predictors of positive surgical margin and BFS. Results: Among the 129 high-risk prostate cancer patients included, 80 (62% patients received LRP and 49 (38% patients received RaLRP. There was no significant difference of positive surgical margin and biochemical recurrence rate between RaLRP and LRP group (P = 0.802 and 0.292. Higher pathological T stage predicted an increased likelihood of positive margins (OR = 3.44, 95% CI [1.45, 8.18], P = 0.005. Higher initial PSA level (HR = 2.88, 95% CI [1.04, 7.94], P = 0.041 and positive surgical margin (HR = 2.55, 95% CI [1.20, 5.44], P = 0.015 were poor prognostic factors for BFS. Conclusion: RaLRP can be considered among high-risk prostate cancer in Asian people with comparable oncological outcomes to LRP. Higher pathological T stage was associated with increased likelihood of positive margins, patients with higher iPSA level and positive surgical margin had worsen biochemical recurrence-free survival.

Laparoscopic management of annexes is now accepted as alternative to classical management by laparotomy. However, a careful pre-operative evaluation, including clinical and ultrasonographic examination is of ut most importance in order to exclude malignant lesion which should be treated by laparotomy. The laparoscopic treatment includes several procedures: intra-peritoneal cystectomy, extra-abdominal cystectomy, oaphorectomy and adnexectomy. These procedures and used according to the laparoscopic diagnosis. About 652 cases managed by laparoscopy, we can concluded: laparoscopic diagnosis of benign lesion is reliable (positive predictive value 100%); most of benign ovarian cysts can be treated by laparoscopy, from 89 to 97% of the benign adnexal cysts; complications are uncommon (8 cases out of 616 patients); the recurrence risk appears to be low (only 2.7% in patients treated for a non endometriotic adnexal cysts).

2015-09-01

Laparoscopy is an increasingly used approach in the surgical treatment of rectal cancer and prostate cancer. The anatomical proximity of the two organs is the main reason to consider performing both procedures simultaneously. To present our first experience of laparoscopic rectal resection and radical prostatectomy, performed simultaneously, in 3 patients. The first patient was diagnosed with locally advanced rectal cancer and tumor infiltration of the prostate and seminal vesicles. The other 2 patients were diagnosed with tumor duplicity. The surgery of the first patient started with laparoscopic prostatectomy except division of the prostate from the rectal wall. The next step was resection of the rectum, extralevator amputation of the rectum and vesicourethral anastomosis. In the other patients, resection of the rectum, followed by radical prostatectomy, was performed. The median follow-up was 12 months. The median operation time was 4 h 40 min, with blood loss of 300 ml. The operations and postoperative course were without incident in the case of 2 patients. However, 1 patient had stercoral peritonitis and a vesicorectal fistula in the early postoperative stage. Sigmoidostomy and postponed ureteroileal conduit were carried out. All patients were in oncologic remission. Combined laparoscopic rectal resection and radical prostatectomy is a viable option for selected patients with locally advanced rectal cancer or tumor duplication. The procedures were completed without complications in 2 out of 3 patients.

Full Text Available PURPOSE: To assess the feasibility and performance of radical cystectomy with urinary diversion using exclusively regional anesthesia (i.e. combined spinal thoracic epidural anesthesia, CSTEA. MATERIALS AND METHODS: In 2011 radical cystectomy with extended pelvic and iliac lymphadenectomy was performed on 14 patients using urinary diversion without applying general anesthesia. Under maintained spontaneous breathing, the patients were awake and responsive during the entire procedure. Postoperatively, pain management took three days with the remaining epidural catheter before oral analgesics were administered. Mobilization and diet restoration were carried out according to the fast-track concept. Outcome measurements included operative time, blood loss, beginning of oral nutrition, beginning of mobilization, postoperative pain levels using numerical and visual analog scales (NAS/VAS, length of hospital stay. RESULTS: All surgical procedures were performed without any complications. The absence of general anesthesia did not result in any relevant disadvantages. The postoperative progress was normal in all patients. Particularly, cardiopulmonary complications and enteroparesis did not occur. The provided palliative care proved sufficient (NAS max. 3-4. Discharge followed 10 to 22 days after surgery. At the time of discharge, the patients described the procedure to be relatively positive. CONCLUSIONS: Our data show that CSTEA is an effective technique for radical cystectomy, whereby spontaneous breathing and reduced interference with the cardiopulmonary system potentially lower the perioperative risks especially for high-risk patients. We recommend practice of CSTEA for radical cystectomy to further evaluate and monitor the safety, efficacy, outcomes, and complications of CSTEA.

Radical retropubic prostatectomy (RRP) performed laparoscopically is a popular treatment with curative intent for organ-confined prostate cancer. After surgery, prostate specific antigen (PSA) levels drop to low levels which can be measured with ultrasensitive assays. This has been described in the literature for open RRP but not for laparoscopic RRP. This paper describes PSA changes in the first 300 consecutive patients undergoing non-robotic laparoscopic RRP by a single surgeon. To use ultrasensitive PSA (uPSA) assays to measure a PSA nadir in patients having laparoscopic radical prostatectomy below levels recorded by standard assays. The aim was to use uPSA nadir at 3 months' post-prostatectomy as an early surrogate end-point of oncological outcome. In so doing, laparoscopic oncological outcomes could then be compared with published results from other open radical prostatectomy series with similar end-points. Furthermore, this end-point could be used in the assessment of the surgeon's learning curve. Prospective, comprehensive, demographic, clinical, biochemical and operative data were collected from all patients undergoing non-robotic laparoscopic RRP. We present data from the first 300 consecutive patients undergoing laparoscopic RRP by a single surgeon. uPSA was measured every 3 months post surgery. Median follow-up was 29 months (minimum 3 months). The likelihood of reaching a uPSA of bench-marking performance. With experience, a surgeon can achieve in excess of an 80% chance of obtaining a uPSA nadir of < or = 0.01 ng/ml at 3 months after laparoscopic RRP for a British population. This is equivalent to most published open series.

The role of minimally invasive surgery in the surgical management of gallbladder cancer is a matter of controversy. Because of the authors' growing experience with laparoscopic liver and pancreatic surgery, they have begun offering patients laparoscopic completion partial hepatectomies of the gallbladder bed with laparoscopic hepatoduodenal lymphadenectomy. The video shows the steps needed to perform laparoscopic resection of the residual gallbladder bed, the hepatoduodenal lymph node nodes, and the residual cystic duct stump in a setting with a positive cystic stump margin. The skin and fascia around the previous extraction site are resected, and this site is used for specimen retrieval during the second operation. To date, three patients have undergone laparoscopic radical cholecystectomy with hepatoduodenal lymph node dissection for gallbladder cancer. The average number of lymph nodes retrieved was 3 (range, 1-6), and the average estimated blood loss was 117 ml (range, 50-200 ml). The average operative time was 227 min (range, 120-360 min), and the average hospital length of stay was 4 days (range, 3-5 days). No morbidity or mortality was observed during 90 days of follow-up for each patient. Although controversy exists as to the best surgical approach for gallbladder cancer diagnosed after routine laparoscopic cholecystectomy, the minimally invasive approach seems feasible and safe, even after previous hepatobiliary surgery. If the previous extraction site cannot be ascertained, all port sites can be excised locally. Larger studies are needed to determine whether the minimally invasive approach to postoperatively diagnosed early-stage gallbladder cancer has any drawbacks.

To explore the feasibility of subserosal injection of carbon nanoparticle via venous infusion needle to label lymph node and its application value in laparoscopic radical gastrectomy. Forty patients with gastric cancer were randomly divided into two groups (carbon nanoparticle group and control group). Subserosal injection of carbon nanoparticle around the tumor was performed via venous infusion needle laparoscopically at the beginning of surgery in carbon nanoparticles group, while the patients routinely underwent laparoscopic radical gastrectomy in control group. Results of harvested lymph nodes were compared between the two groups. The perioperative complications and the side effect of carbon nanoparticle were also evaluated. The average number of harvested lymph node in carbon nanoparticle group (31.7±7.6) was significantly higher than that in control group (19.8±6.1, Pinjection of carbon nanoparticle via venous infusion needle to label lymph nodes during laparoscopic radical gastrectomy is safe and feasible. It can increase the number of harvested lymph node, especially the small node.

Purpose: The role of preoperative radiotherapy for patients with muscle-invasive bladder cancer remains controversial. Since 1985, the primary modality for treatment of these patients at our institution has been radical cystectomy alone. Prior to that time, the use of preoperative radiotherapy and cystectomy had been the mainstay of treatment. In this retrospective review we compare the results of these treatments, focusing on local control. Methods and Materials: The preoperative radiotherapy and radical cystectomy (PREOP) group was comprised of 338 patients with muscle-invasive (Stages T2-T4) transitional cell carcinoma of the bladder treated between 1960 and 1983. A mean total dose of 49.3 {+-} 0.2 Gy ({+-} SE) was administered at 2 Gy per fraction 4-6 weeks prior to cystectomy. The radical cystectomy alone (CYST) group was comprised of 232 patients treated between 1985 and 1990. The median follow-up for the PREOP group was 91 months and for the CYST group was 54 months. Only those patients who completed planned PREOP (n = 301) and CYST (n = 220) treatments were included in the analyses described below. Results: The treatment groups were stratified by clinical stage and compared in terms of actuarial local control. There were no differences between the groups for Stage T2 or T3a patients, and there were not enough Stage T4 patients in the PREOP group with which to make a meaningful comparison. However, for those with T3b disease, actuarial 5 year local control for the PREOP group (n = 92) was 91%, compared to 72% for the CYST group (n = 43). This difference was significant at p = 0.003 (log rank). Patients with T3b disease who received PREOP also fared slightly better at 5 years in terms of freedom from distant metastasis (67% vs. 54%), disease freedom (59% vs. 47%), and overall survival (52% vs. 40%); although, these differences did not reach statistical significance. The distribution of prognostic factors in the groups was analyzed to determine if this could

Xavier Cathelineau

2010-04-01

Full Text Available PURPOSE: To review the literature and present a current picture of the evolution in radical prostatectomy from the laparoscopic point of view. MATERIALS AND METHODS: We conducted an extensive Medline literature search. Articles obtained regarding laparoscopic radical prostatectomy (LRP and our experience at Institut Montsouris were used for reassessing anatomical and technical issues in radical prostatectomy. RESULTS: LRP nuances were reassessed by surgical teams in order to verify possible weaknesses in their performance. Our basic approach was to carefully study the anatomy and pioneer open surgery descriptions in order to standardized and master a technique. The learning curve is presented in terms of an objective evaluation of outcomes for cancer control and functional results. In terms of technique-outcomes, there are several key elements in radical prostatectomy, such as dorsal vein control-apex exposure and nerve sparing with particular implications in oncological and functional results. Major variations among the surgical teams' performance and follow-up prevented objective comparisons in radical prostatectomy. The remarkable evolution of LRP needs to be supported by comprehensive results. CONCLUSIONS: Radical prostatectomy is a complex surgical operation with difficult objectives. Surgical technique should be standardized in order to allow an adequate and reliable performance in all settings, keeping in mind that cancer control remains the primary objective. Reassessing anatomy and a return to basics in surgical technique is the means to improve outcomes and overcome the difficult task of the learning curve, especially in minimally access urological surgery.

Choroidal and Cutaneous Metastasis from Urothelial Carcinoma of the Bladder after Radical Cystectomy: A Case Report and Literature Review

Full Text Available Bladder cancer is the second most common genitourinary malignancy and has variable metastatic potential; however, choroidal and cutaneous metastases are extremely rare. Generally, a patient with these uncommon metastases has a very poor prognosis. We present a bladder cancer patient with a visual disorder in the right eye and multiple nodules on head and lower abdomen that developed 17 months after a radical cystectomy. These symptoms were determined to be caused by choroidal and cutaneous metastasis of bladder cancer. Although two cycles of combination chemotherapy were performed, the patient died 5 months after diagnosis of multiple metastases.

To compare perioperative morbidity and oncological outcomes of robot-assisted laparoscopic radical cystectomy (RARC) to open RC (ORC) at a single institution. A retrospective analysis was performed on a consecutive series of patients undergoing RC (100 RARC and 100 ORC) at Wake Forest University with curative intent from 2006 until 2010. Complication data using the Clavien system were collected for 90 days postoperatively. Complications and other perioperative outcomes were compared between patient groups. Patients in both groups had comparable preoperative characteristics. The overall and major complication (Clavien ≥ 3) rates were lower for RARC patients at 35 vs 57% (P = 0.001) and 10 vs 22% (P = 0.019), respectively. There were no significant differences between groups for pathological outcomes, including stage, number of nodes harvested or positive margin rates. Our data suggest that patients undergoing RARC have perioperative oncological outcomes comparable with ORC, with fewer overall or major complications. Definitive claims about comparative outcomes with RARC require results from larger, randomised controlled trials. Copyright © 2014 Elsevier Inc. All rights reserved.

The aim of this study was to evaluate the clinical use of [(18)F]fluorodeoxyglucose-positron emission tomography/computed tomography (FDG-PET/CT) in addition to conventional preoperative radiological investigations in a defined group of patients with high-risk muscle-invasive bladder cancer. In total, 103 patients with high-risk muscle-invasive bladder cancer defined as stage T3/T4 disease or as stage T2 with hydronephrosis or high-risk histological features, who were provisionally scheduled to undergo cystectomy, were prospectively recruited to the study. The patients were referred to FDG-PET/CT in addition to standard preoperative investigation with computed tomography (CT). The final treatment decision was reached at a multidisciplinary conference based on all available information including the FDG-PET/CT findings. Compared to CT alone, FDG-PET/CT provided more supplemental findings suggesting malignant manifestations in 48 (47%) of the 103 patients. The additional FDG-PET/CT findings led to an altered provisional treatment plan in 28 out of 103 patients (27%), detection of disseminated bladder cancer and subsequent cancellation of the initially intended cystectomy in 16 patients, and identification of disseminated disease and treatment with induction chemotherapy before radical cystectomy in 12 patients. Preoperative FDG-PET/CT changed the treatment plan for a considerable proportion (27%) of the present patients. Accordingly, such examination can potentially improve the preoperative staging of cystectomy patients with high-risk features, and may also reduce the number of futile operations in patients with advanced disease who are beyond cure.

Radical cystectomy with orthotopic neobladder for invasive bladder cancer: a critical analysis of long term oncological, functional and quality of life results

Directory of Open Access Journals (Sweden)

Arnulf Stenzl

2010-10-01

Full Text Available PURPOSE: Analyze current knowledge and practice regarding tumor-related cystectomy with subsequent orthotopic neobladder both in male and female patients. DESIGN, SETTING, AND PARTICIPANTS: Evaluate literature predominantly from the last decade dealing with long-term experience in large numbers of patients with an orthotopic neobladder following cystectomy. Oncological outcome specific to an orthotopic neobladder, functional aspects such as urinary continence, renal function, sexual activity and other quality of life issues are elucidated. RESULTS: Local pelvic recurrences after urothelial bladder cancer occur in 7-12%. Urethral second primary tumors in male and female patients in contemporary series with bladder substitution are 4-6% and 1.4 o 4%, respectively. Upper tract recurrences vary between 2.4-17%. Complications regarding the upper urinary tract have dramatically diminished due to simplified forms of upper tract protection as well as a more refined technique of ureterointestinal anastomosis. Depending on the technique ureteroileal stenosis was lately reported to lie between 2.7 to 3.8%. Renal function remained stable in 96% after a mean follow-up of up to 5 years. Radical cystectomy in carefully selected patients has stood the test of time by providing adequate long-term survival and low local recurrence rates. Orthotopic bladder substitution does not compromise oncological outcome, yields excellent functional results, is cost effective compared to other types of urinary diversion, may improve quality of life and should therefore be the diversion of choice both in men and women. Chronological age is generally not a contraindication for cystectomy, but for orthotopic urinary diversion, tumor extent, functional pelvic floor deficits and general life expectancy are limiting factors.

Orgasm associated incontinence, that is the inadvertent leakage of urine at orgasm, has received little attention in the literature. We evaluated the rate of occurrence of orgasm associated incontinence following radical pelvic surgery as well as its associated factors and predictors. From January 2005 to March 2006, 696 patients were evaluated for post-radical pelvic surgery sexual dysfunction. A database was created, and descriptive statistics, chi-square analysis and logistic regression analysis were used to evaluate associated factors and predictors. Of 475 patients 96 (20%) reported orgasm associated incontinence following radical pelvic surgery. The incidence was significantly less in the cystoprostatectomy group than in the open and laparoscopic radical prostatectomy groups (p Orgasm associated incontinence was more commonly found within 12 months following surgery vs greater than 12 months (RR 0.81, 95% CI 0.72-0.92, p orgasm associated pain (RR 1.09, 95% CI 1.01-1.16, p Orgasm associated incontinence was not associated with patient age, the degree of nerve sparing, surgical margin status, seminal vesicle or lymph node involvement, preoperative erectile function, nocturnal erections, libido level or daytime continence. Orgasm associated incontinence occurs in a fifth of men (96 of 475) following radical pelvic surgery. The incidence of orgasm associated incontinence is greater with radical prostatectomy than with radical cystectomy and it is unrelated to the type of prostatectomy performed (open vs laparoscopic). Orgasm associated incontinence is more likely to be reported within year 1 following surgery and in men who complain of orgasmic pain and/or penile shortening.

Purpose: The objective of this study is to describe the use and outcome of radical radiotherapy for bladder cancer in the province of Ontario, Canada, between 1982 and 1994. Methods: Electronic records of invasive bladder cancer (ICD code 188) from the Ontario Cancer Registry were linked to surgical records from all Ontario hospitals and radiotherapy (RT) records from all Ontario cancer centers. We identified cases receiving radical RT by selecting RT records containing 'bladder' or 'pelvis' anatomic region codes and a radical or curative intent code (or dose > 39.5 Gy if intent missing). We identified cases receiving salvage total cystectomy by selecting total cystectomy procedure codes occurring at any time beyond 4 months from the start of radical RT. We used life table methods to compute the following: the time from diagnosis to radical RT, the time from radical RT to salvage cystectomy, overall and cause-specific survival from radical radiotherapy to death, and overall and cause-specific survival from salvage cystectomy to death. We modeled the factors associated with time to death, time to cystectomy conditional on survival, and time to cystectomy or death, whichever came first, using Cox proportional hazards regression. Results: From the 20,906 new cases of bladder cancer diagnosed in Ontario from 1982 to 1994, we identified 1,372 cases treated by radical radiotherapy (78% male, 22% female; mean age 69.8 years). The median interval to start of radical RT from diagnosis was 13.4 weeks. Ninety-three percent of patients were treated on high-energy linacs, and the most common dose/fractionation scheme was 60 Gy/30 (31% of cases). Five-year survival rates were as follows: bladder cancer cause-specific, 41%; overall, 28%; cystectomy-free, 25%; bladder cancer cause-specific following salvage cystectomy, 36%; overall following salvage cystectomy, 28%. Factors associated with a higher risk of death and a poorer cystectomy-free survival were histology (squamous or

Full Text Available PURPOSE: To report the 5-year oncological outcomes of patients undergoing laparoscopic radical nephrectomy for renal cancer compared to a cohort of patients undergoing open radical nephrectomy. METHODS: We retrospectively analyzed the data of 88 patients undergoing radical nephrectomy for renal cell carcinoma prior to January 2000. Of these, 45 patients underwent laparoscopic radical nephrectomy, and 43 patients underwent open radical nephrectomy. Inclusion criteria comprised clinically organ-confined tumors of 15 cm or less in size without concomitant lymphadenopathy or vena cava thrombus. Oncological follow-up data were obtained from charts, radiological reports, and phone calls to patients or their families, and were calculated from the date of surgery to the date of last appointment with physician or date of death. RESULTS: All laparoscopic procedures were completed without open conversion. On comparing the laparoscopic radical nephrectomy and open radical nephrectomy groups, mean tumor size was 5. 8 vs 6.2 cm (P = . 44, mean blood loss was 183 vs 461 mL (P = . 004, and mean operative time was 2.8 vs 3.7 hrs (P OBJETIVO: Relatar os resultados oncológicos após 5 anos de seguimento em pacientes submetidos a nefrectomia radical laparoscópica para tratamento do câncer renal, comparando esses com os resultados obtidos com um grupo de pacientes submetidos a nefrectomia radical aberta.

Full Text Available Primary signet-ring cell adenocarcinoma of bladder is a rare neoplasm, usually seen in middle age adults. We report the case of an 18-year-old man who presented with intermittent gross hematuria. Computed tomography imaging showed multifilling defects in the bladder. The patient underwent a transurethral resection of the bladder tumor. Histological findings were consistent with poorly differentiated mixed mucinous and signet-ring cell adenocarcinoma. We ruled out other possible origins of tumor by gastrointestinal endoscopy and colonoscopy. The patient was treated with radical cystectomy with prostate and seminal vesicle sparing technique and orthotopic diversion using “W” ileum pouch with pelvic lymphadenectomy to the bifurcation of the aorta was done. Six-month follow-up of patient showed normal conditions without metastatic spread or any recurrence.

The goal of our study was to report on the feasibility of outpatient laparoscopic radical hysterectomy in patients with early-stage cervical cancer. We included all patients who underwent a laparoscopic radical hysterectomy at the Instituto de Cancerología - Las Americas in Medellin, Colombia, between January 2013 and July 2015. The control group was a similar cohort of patients who were admitted after their surgery. Seventy-six patients were included [outpatient (31) and admitted (45)]. There were no statistically significant differences between groups regarding age, clinical stage, histology, nodal count, need of adjuvant treatment, visual pain scores at discharge or follow up time. All patients underwent a transversus abdominis plane block. The median operative time was 150min (range, 105-240) in the outpatient group vs. 170min (range, 97-300) in the admitted group (p=0.023). The median estimated blood loss was 50ml (range, 20-150) in the outpatient group vs. 120ml (range, 20-1000) in the admitted group (p=0.001). All patients were able to void spontaneously and tolerate a diet before discharge. In patients who were admitted, the median hospital stay was 1day, (range; 1-6), and 39 (87%) were discharged at postoperative day 1. There were 6 postoperative complications, 3 in each group. There were no recurrences in the follow-up period in the outpatient group, and there were 3 (6.6%) recurrences in the admitted group. Outpatient laparoscopic radical hysterectomy is feasible and can be performed safely in a developing country in well-selected patients. Copyright © 2016. Published by Elsevier Inc.

Pure laparoscopic radical resection of hilar cholangiocarcinoma is still a challenging procedure, in which laparoscopic lymphadenectomy, hemihepatectomy with caudate lobectomy, and hepaticojejunostomy were included [1-4]. Relative report is rare in the world up to now. Hilar cholangiocarcinoma has a poor prognosis, especially when it occurs with lymph node metastasis or vessel invasion [5, 6]. We recently had a patient who underwent a pure laparoscopic extended right hepatectomy and lymph node dissection and hepaticojejunostomy for a type IIIa hilar cholangiocarcinoma. The tumor was 20 × 15 × 12 mm in diameter and located in the right bile duct and common hepatic duct. Radiological examination showed that hepatic artery and portal vein was not invaded. After the division and mutilation of the right hepatic artery and the right portal vein, short hepatic veins were divided and cut off with clip and ultrasound knife from the anterior face of the vena cava. Mobilization was performed after the devascularization of the right liver, followed by the transection of liver parenchymal with CUSA and ultrasound knife. Finally, left hepatic bile duct jejunum Roux-en-Y reconstruction was performed. This patient underwent successfully with a totally laparoscopic procedure. An extended right hepatectomy (right hemihepatectomy combined with caudate lobectomy) and complete lymph node dissection and hepaticojejunostomy were performed in this operation. The operation time was nearly 590 min, and the intraoperative blood loss was about 300 ml. No obvious complication was observed and the postoperative hospital stay was 11 days. The final diagnosis of the hilar cholangiocarcinoma with no lymph node metastasis was pT2bN0M0 stage II (American Joint Committee on Cancer, AJCC). Pure laparoscopic resection for hilar cholangiocarcinoma was proved safe and feasible, which enabled the patient to recover early and have an opportunity to receive chemotherapy as soon as possible.

Full Text Available Radical cystectomy remains the standard treatment for muscle-invasive carcinoma bladder. Various methods have been described for the urinary diversion. In the last 150 years urinary diversion has evolved from cutaneous ureterostomy to the orthotopic neobladder. Especially during the last 20 years, much advancement has been made. We hereby have reviewed the current approaches being used at different centers in India. We have also analyzed the evolution of diversion from conduit to the orthotopic substitution at our center.

Radical cystectomy followed by urinary diversion or reconstruction (RC) is a standard treatment for patients with muscle-invasive bladder cancer. In these operations, a high frequency of complications, especially postoperative infection, has been reported. However, there have only been a few studies about postoperative anaerobic bacterial infection. To clarify the significance and role of anaerobic bacteria in postoperative infection, we retrospectively analyzed cases in which postoperative infection by these organisms developed. A total of 126 patients who underwent RC from 2006 to 2010 were included in this study. Various types of postoperative infection occurred in 66 patients. Anaerobic bacterial infections were detected with cultures for urine and blood in one case, for blood in two cases, and for surgical wound pus in four. The frequency of postoperative anaerobic bacterial infection in RC was less than that of colon surgery. However, this study revealed the possible development of a nonnegligible number of postoperative anaerobic bacterial infections. Therefore, we should consider anaerobic bacteria as possible pathogens in postoperative infection after RC.

Full Text Available Treatment of urachal adenocarcinoma (UA of the urinary bladder has typically been with radical cystectomy (RC but more conservative approaches are gaining popularity. Here we present the case of a female patient with metastatic primary bladder UA who was treated with robotic partial cystectomy (RPC and adjuvant chemotherapy; she is alive with no evidence of disease recurrence or metastatic disease at 5 years. This case provides some of the longest follow-up after RPC to date thereby demonstrating that RPC is a safe and oncologically viable treatment for selected patients even several years after definitive treatment. Patients undergoing RPC benefit from the reduced morbidity associated with this less radical treatment whilst enjoying similarly successful oncological outcomes to RC.

To guide the surgeon during laparoscopic or robot-assisted radical prostatectomy an innovative laparoscopic/ultrasound fusion platform was developed using a motorized 3-dimensional transurethral ultrasound probe. We present what is to our knowledge the first preclinical evaluation of 3-dimensional prostate visualization using transurethral ultrasound and the preliminary results of this new augmented reality. The transurethral probe and laparoscopic/ultrasound registration were tested on realistic prostate phantoms made of standard polyvinyl chloride. The quality of transurethral ultrasound images and the detection of passive markers placed on the prostate surface were evaluated on 2-dimensional dynamic views and 3-dimensional reconstructions. The feasibility, precision and reproducibility of laparoscopic/transurethral ultrasound registration was then determined using 4, 5, 6 and 7 markers to assess the optimal amount needed. The root mean square error was calculated for each registration and the median root mean square error and IQR were calculated according to the number of markers. The transurethral ultrasound probe was easy to manipulate and the prostatic capsule was well visualized in 2 and 3 dimensions. Passive markers could precisely be localized in the volume. Laparoscopic/transurethral ultrasound registration procedures were performed on 74 phantoms of various sizes and shapes. All were successful. The median root mean square error of 1.1 mm (IQR 0.8-1.4) was significantly associated with the number of landmarks (p = 0.001). The highest accuracy was achieved using 6 markers. However, prostate volume did not affect registration precision. Transurethral ultrasound provided high quality prostate reconstruction and easy marker detection. Laparoscopic/ultrasound registration was successful with acceptable mm precision. Further investigations are necessary to achieve sub mm accuracy and assess feasibility in a human model.

Patients with bladder cancer who present with hydronephrosis may require drainage of the affected kidney before receiving further cancer treatment. Drainage can be done by retrograde stenting or percutaneously. However, retrograde stenting carries the risk of tumor cell spillage to the upper urinary tract. The aim of this study was to evaluate whether patients with bladder cancer are at higher risk for upper urinary tract recurrence if retrograde stenting has been performed prior to radical cystectomy. We retrospectively analyzed the records of 1,005 consecutive patients with bladder cancer who underwent radical cystectomy at our department between January 2000 and June 2016. Negative intraoperative ureteral margins were mandatory for study inclusion. Patients received regular followup according to our institutional protocol, including imaging of the upper urinary tract and urine cytology. Preoperative drainage of the upper urinary tract was performed in 114 of the 1,005 patients (11%), including in 53 (46%) by Double-J® stenting and in 61 (54%) by percutaneous nephrostomy. Recurrence developed in the upper urinary tract in 31 patients (3%) at a median of 17 months after cystectomy, including 7 of 53 (13%) in the Double-J group, 0% in the nephrostomy group and 24 of 891 (3%) in the no drainage group. Multivariate regression analysis revealed a higher risk of upper urinary tract recurrence if patients underwent Double-J stenting (HR 4.54, 95% CI 1.43-14.38, p = 0.01) and preoperative intravesical instillations (HR 2.94, 95% CI 1.40-6.16, p = 0.004). Patients who undergo Double-J stenting prior to radical cystectomy are at higher risk for upper urinary tract recurrence. If preoperative upper urinary tract drainage is required, percutaneous drainage might be recommended. Copyright © 2017 American Urological Association Education and Research, Inc.

Summarizing the evidence on the effects of pre- and postoperative exercise and psychosocial rehabilitation interventions on patient-reported outcomes (PROs) and physical fitness in bladder cancer patients undergoing radical cystectomy. The Cochrane Central Register of Controlled Trials, MEDLINE, Embase, Web of Science and the Physiotherapy Evidence Database were searched independently by two authors from inception until 10 November 2017. Cited references of the studies and citing references retrieved via Web of Science were also checked. Randomized controlled trials (RCTs) and non-randomized studies assessing effects of exercise and psychosocial interventions in bladder cancer patients undergoing radical cystectomy were eligible. Primary outcome measures were PROs and physical fitness. Risk of bias was assessed using the Cochrane Collaboration tool and the Newcastle-Ottawa Scale. Five RCTs (three exercise and two psychosocial studies) and one non-randomized psychosocial study comprising 317 bladder cancer patients were included. Timing of the intervention was preoperative ( n = 2), postoperative ( n = 2) or both pre- and postoperative ( n = 2). Positive effects of exercise were found for physical fitness ( n = 3), some health-related quality-of-life (HRQoL) domains ( n = 2), personal activities in daily living ( n = 1) and muscle strength ( n = 1). Psychosocial interventions showed positive effects on anxiety ( n = 1), fatigue ( n = 1), depression ( n = 1), HRQoL ( n = 1) and posttraumatic growth ( n = 1). Quality assessment showed most shortcomings with sample sizes and strong heterogeneity was observed between studies. The evidence relating to the effects of exercise in bladder cancer is very limited and is even less for psychosocial interventions.

Patients being treated for bladder cancer share issues in common with other cancer patients, but also experience issues that are unique to their surgical treatment. This study used a descriptive qualitative approach to explore the experiences of patients who had undergone radical cystectomy for bladder cancer Twenty-two participants were interviewed in-depth on one occasion and were invited to attend a focus group session following the analysis of the interview transcripts. Participants described the shock of their diagnosis, their lack of information about bladder cancer, the importance of clear communication with care providers, and the types of adjustments they had to make following surgery. Specifically, changes in bodily function, body image, sexual relationships, and intimacy presented challenges for these participants. Although there was a sense of acceptance about the treatment-related events, there were still significant adjustments required by individuals following their surgery. Information, open communication, and support from family and friends were seen as important factors in helping patients adjust after surgery. Patients require clear, concise and consistent information about their cancer, treatment options, and course of care. Nurses caring for patients following surgery for bladder cancer need to understand the unique needs of these patients.

Llorente, C; López, B; Hernández, V; Guijarro, A; Pérez-Fernández, E

In the literature, mortality for radical cystectomy (RC) varies between 2.3% and 7.5%. In Spain, there are no published general data on morbidity and mortality. To identify the complications and mortality of RC in Spain through an analysis of all procedures performed over a 3-year period and to study the geographic variability of these results. We identified patients who underwent RC in the Spanish National Health System between 2011 and 2013 based on the minimum basic data set. We analysed the complications and mortality during hospitalisation and at 30, 60 and 90 days. We compared these results in the various autonomous communities, adjusted them by age, Charlson score and sex and subsequently added the hospital size. We studied 7999 patients who underwent RC in 197 hospitals of the Spanish National Health System. The mean age of the series was 67.2±9.8 years. The median stay was 15 days (IQR, 11-24). Some 47.2% of the patients had complications. The mean mortality in-hospital and at 30, 60 and 90 days was 4.7, 2.9, 5 and 6.2%, respectively. There was considerable variability in the mortality at 90 days among the communities (3.8-9.1%). When adjusting by the patient and hospital characteristics, there were still significant geographic variations (3.8-11.5%). RC mortality in Spain at 90 days is similar to the rate in the literature. There are significant geographic variations unexplained by the characteristics of the patients or by those of the hospitals in which these operations were performed. Copyright © 2016.

Robotic Assisted Radical Cystoprostatectomy and Intracorporeal Ileal Conduit Urinary Diversion for a Kidney Transplant Recipient

Directory of Open Access Journals (Sweden)

Peter A. Caputo

Full Text Available ABSTRACT Introduction and Objectives: Robotic assisted radical cystectomy (RARC is an alternative to open radical cystectomy. As experience is gained with the RARC approach the technique is being applied to more complex surgical cases. We describe here our technique for RARC with intracorporeal ileal conduit urinary diversion for a renal transplant recipient. Materials and Methods: The patient is a 60-year old man with high-grade muscle invasive bladder cancer. He has a history of renal failure due to polycystic kidney disease and received a deceased donor renal transplant in 2008. His hospital course at time of transplant was complicated by low-level BK virus viremia. Interestingly his trans-urethral bladder tumor resection specimen at time of bladder cancer diagnosis stained positive for SV40. His native kidneys were anuric so bilateral laparoscopic nephrectomy was performed in a staged fashion 2 weeks prior to RARC. Our surgical technique utilizes 6 trocars, of note a 12-mm assistant trocar is placed 1 cm superior to the pubic symphysis, and this trocar is solely used to pass a laparoscopic stapler to facilitate the excision of the ileal segment and the stapled enteric anastomosis. Surgical steps include: identification of native ureters bilaterally (removed en bloc with the bladder specimen; identification of the transplanted ureter at the right bladder dome; posterior bladder and prostate dissection along Denonvilliers’ fascia; development of the space of Retzius; ligation and transection of the bladder and prostate vascular bundles; apical prostate dissection and transection of urethra; left pelvic lymphadenectomy; ilium resection for creation of the ileal conduit; stapled enteric anastomosis; ureteroileal anastomosis; maturation of the ileal conduit stoma. Results: The surgery had no intraoperative complications. Operative time was 443 minutes (7.4 hours. Estimated blood loss was 250 cc. Length of hospital stay was 5 days. The patient

To examine the feasibility of image-guided navigation using transrectal ultrasound (TRUS) to visualize the neurovascular bundle (NVB) during robot-assisted laparoscopic radical prostatectomy (RALP). The preservation of the NVB during radical prostatectomy improves the postoperative recovery of sexual potency. The accompanying blood vessels in the NVB can serve as a macroscopic landmark to localize the microscopic cavernous nerves in the NVB. A novel, robotic transrectal ultrasound probe manipulator (TRUS Robot) and three-dimensional (3-D) reconstruction software were developed and used concurrently with the daVinci surgical robot (Intuitive Surgical, Inc., Sunnyvale, CA) in a tandem-robot assisted laparoscopic radical prostatectomy (T-RALP). After appropriate approval and informed consent were obtained, 3 subjects underwent T-RALP without associated complications. The TRUS Robot allowed a steady handling and remote manipulation of the TRUS probe during T-RALP. It also tracked the TRUS probe position accurately and allowed 3-D image reconstruction of the prostate and surrounding structures. Image navigation was performed by observing the tips of the daVinci surgical instruments in the live TRUS image. Blood vessels in the NVB were visualized using Doppler ultrasound. Intraoperative 3-D image-guided navigation in T-RALP is feasible. The use of TRUS during radical prostatectomy can potentially improve the visualization and preservation of the NVB. Further studies are needed to assess the clinical benefit of T-RALP. Copyright © 2011 Elsevier Inc. All rights reserved.

The safety of laparoscopic management of benign ovarian cysts has been demonstrated. The size of the benign ovarian cyst continues to be a limiting factor for laparoscopic surgery, with most surgeons choosing laparotomy for large cysts. A 15-year-old woman had a 22-cm, benign ovarian cyst extending above the umbilicus that was managed successfully with laparoscopy. We performed prelaparoscopy cyst drainage with a suprapubic Bonanno catheter (Becton Dickinson, Rutherford, New Jersey) followed by laparoscopic cystectomy. Because of its coiled end, the Bonanno catheter is less likely to result in cyst leakage around the aspiration site. With proper patient selection, laparoscopic surgery can be safely applied in a select group of patients with large, benign ovarian cysts.

Laparoscopic resection of tumor recurrence after radical nephrectomy for localized renal cell carcinoma.

Local recurrence of Renal Cell Carcinoma (RCC) after radical nephrectomy is a rare event. Some known risk factors are: clinical/pathological stage, locorregional disease and lyimph node positivity. Since up to 30-40% of patients can achieve a disease-free status, we show a case (video) in which we performed a laparoscopic excision of a local RCC, taking advantage of all the well-known benefits of laparoscopy. A 56 years old female with a history of open radical nephrectomy two years before was diagnosed with a mass at the time of surveillance CT imaging during follow-up. The suspected local recurrence was 12 cm, and vascularized predominantly by tributaries originating from the iliac vessels. There was no other site of disease (i.e. brain, lung, liver, bones) and laboratory tests were normal. Laparoscopic approach was approached, by inserting 4 trocars (2 of 10 and 2 of 5mm) with the patient in the lateral position. The procedure lasted 130 minutes, with 220 mL of estimated bleeding; the larger vessels were ligated with polymer clips (Hem-o-lok) and the smaller handled by ultrasonic clamp. The specimen was removed by a small incision below the umbilicus in an appropriate bag. The patient was feed in the first postoperative day and discharged on the third day. Histopathology revealed sarcoma, with a high degree of mitosis, and negative surgical margins. She was referred to medical oncology for adjuvant therapy consideration. The laparoscopic resection of recurrent tumor should be encouraged in highly selected cases. The minimally invasive method, with its known advantages, especially for more debilitated patients, can be advantageous when applied to suitable cases.

To determine the incidence of spreading bladder transitional cell carcinoma and primary adenocarcinoma to the prostate in patients with bladder cancer undergoing radical cystectomy. From 1995 to 2016, 283 men underwent radical cystectomy with removal of the bladder, perivesical tissue, prostate, seminal vesicles and pelvic lymph nodes. Prostate sparing cystectomy was performed in 45 (13.7%) patients. The whole prostate and the apex of the prostate were preserved in 21 (6.4%) and 24 (7.3%) patients, respectively. The spread of transitional cell cancer of the bladder to the prostate occurred in 50 (15.2%) patients. Twelve (3.6%) patients were found to have primary prostate adenocarcinoma. Clinically significant prostate cancer was diagnosed in 4 (33.3%) patients. We believe that the high oncological risk of prostate sparing cystectomy, despite some functional advantages, dictates the need for complete removal of the prostate in the surgical treatment of bladder cancer.

To evaluate the safety and feasibility of same day-discharge (SDD) after laparoscopic radical hysterectomy for cervix cancer by determining complication rates and factors associated with post-operative admission. In this retrospective cohort study, patients undergoing laparoscopic radical hysterectomy for cervix cancer at a single institution from January 2006 to November 2015 were identified. Admitted patients were compared to same-day discharge patients. Rates of post-operative complications and readmission were analyzed and regression analysis used to determine factors associated with admission. 119 patients were identified. 75 (63%) were SDD patients (mean stay 156.7±50.2min) and 44 (37%) were admitted patients (mean stay 1.2±0.6days). Ten (13%) SDD patients sought medical attention within 30days post-operatively vs. nine (20%) admitted patients (p=0.17). Reasons SDD patients sought attention included pain (n=1), wound concerns (n=2), vaginal bleeding (n=2), DVT/VTE (n=1), fever (n=2) and fistula (n=2). All patients developed symptoms and presented between 5 and 13days post-operatively thus no complications could have been detected or prevented through initial admission. Four SDD patients were readmitted within 30days of surgery (p=0.25), two required re-operation (p=0.16). Admitted patients were older (p=0.049), had longer operations (p=0.02), increased blood loss (p=0.0004), increased intra-operative complications (p=0.001), surgery later in the day (p=0.004) and before April 2010 (p=0.001). On multivariate analysis, older age (OR1.05, p=0.03), surgery later in the day (OR 7.22, p=0.002) and presence of an intra-operative complication (OR 10.25, p=0.02) were significantly associated with admission. Same-day discharge after laparoscopic radical hysterectomy for cervix cancer is safe, with a low risk of post-operative morbidity and hospital readmission. Copyright © 2017 Elsevier Inc.

Some known risk factors are: clinical/pathological stage, locorregional disease and lyimph node positivity. Since up to 30-40% of patients can achieve a disease-free status, we show a case (video in which we performed a laparoscopic excision of a local RCC, taking advantage of all the well-known benefits of laparoscopy.Case report A 56 years old female with a history of open radical nephrectomy two years before was diagnosed with a mass at the time of surveillance CT imaging during follow-up. The suspected local recurrence was 12cm, and vascularized predominantly by tributaries originating from the iliac vessels. There was no other site of disease (i.e. brain, lung, liver, bones and laboratory tests were normal. Laparoscopic approach was approached, by inserting 4 trocars (2 of 10 and 2 of 5mm with the patient in the lateral position.Result The procedure lasted 130 minutes, with 220mL of estimated bleeding; the larger vessels were ligated with polymer clips (Hem-o-lok and the smaller handled by ultrasonic clamp. The specimen was removed by a small incision below the umbilicus in an appropriate bag. The patient was feed in the first postoperative day and discharged on the third day. Histopathology revealed sarcoma, with a high degree of mitosis, and negative surgical margins. She was referred to medical oncology for adjuvant therapy consideration.Conclusion The laparoscopic resection of recurrent tumor should be encouraged in highly selected cases. The minimally invasive method, with its known advantages, especially for more debilitated patients, can be advantageous when applied to suitable cases.

Purpose: To develop multi-institutional consensus clinical target volumes (CTVs) and organs at risk (OARs) for male and female bladder cancer patients undergoing adjuvant radiation therapy (RT) in clinical trials. Methods and Materials: We convened a multidisciplinary group of bladder cancer specialists from 15 centers and 5 countries. Six radiation oncologists and 7 urologists participated in the development of the initial contours. The group proposed initial language for the CTVs and OARs, and each radiation oncologist contoured them on computed tomography scans of a male and female cystectomy patient with input from ≥1 urologist. On the basis of the initial contouring, the group updated its CTV and OAR descriptions. The cystectomy bed, the area of greatest controversy, was contoured by another 6 radiation oncologists, and the cystectomy bed contouring language was again updated. To determine whether the revised language produced consistent contours, CTVs and OARs were redrawn by 6 additional radiation oncologists. We evaluated their contours for level of agreement using the Landis-Koch interpretation of the κ statistic. Results: The group proposed that patients at elevated risk for local-regional failure with negative margins should be treated to the pelvic nodes alone (internal/external iliac, distal common iliac, obturator, and presacral), whereas patients with positive margins should be treated to the pelvic nodes and cystectomy bed. Proposed OARs included the rectum, bowel space, bone marrow, and urinary diversion. Consensus language describing the CTVs and OARs was developed and externally validated. The revised instructions were found to produce consistent contours. Conclusions: Consensus descriptions of CTVs and OARs were successfully developed and can be used in clinical trials of adjuvant radiation therapy for bladder cancer.

In recent years, the laparoscopic approach in oncologic urology seems more attractable to the surgeons. It is considered to have the same oncologic quality as open surgery, but is less invasive in patients. It is used widely in all of Europe, but with various frequency. The aim of the study was to present a various amount of oncourological procedures from three neighbouring countries - Poland, Czech Republic and Hungary. Prostatectomy, cystectomy, nephrectomy and tumorectomy (Nephron Sparing Procedures - NSS) were presented as a list of procedures prepared from the national registry. The total amount of procedures was presented, as well as the LO (Lap to Open procedures) index, P/P (procedures/population) index, ratio of cystectomy/population, and cystectomy/TURBT. In the Czech Republic, the most complex procedures are performed (laparoscopic/robotic prostatectomy, NSS LAP, LAP nephrectomy) in the majority when analysing the country's population. In Hungary and Czech Republic, there are more laparoscopic/robotic radical prostatectomies performed, than open ones. In Poland the largest number of cystectomies is performed when analysing the country's population, but it is difficult to explain the much higher ratio of 6.57 TUR/one cystectomy. In the Czech Republic this procedure is performed in almost one quarter of the patients (23.36%). Interestingly, in Hungary the cystectomy with pouch creation is performed in about 67.65% cases. The highest reimbursement for surgical procedure is present in the Czech Republic with approximately 20-40% more than when compared to Poland or Hungary. The definitive leader in Central Europe (based on the national registry) is the Czech Republic, where the most complex procedures are performed (laparoscopic/robotic prostatectomy, NSS LAP, LAP nephrectomy) in biggest amounts when analysing the country's population. Explanation of such circumstances, can be the higher reimbursement rate for surgical procedure in this country.

To assess the feasibility of radical perineal cystoprostatectomy using the latest generation purpose-built single-port robotic surgical system. In two male cadavers the da Vinci ® SP1098 Surgical System (Intuitive Surgical, Sunnyvale, CA, USA) was used to perform radical perineal cystoprostatectomy and bilateral extended pelvic lymph node dissection (ePLND). New features in this model include enhanced high-definition three-dimensional optics, improved instrument manoeuvrability, and a real-time instrument tracking and guidance system. The surgery was accomplished through a 3-cm perineal incision via a novel robotic single-port system, which accommodates three double-jointed articulating robotic instruments, an articulating camera, and an accessory laparoscopic instrument. The primary outcomes were technical feasibility, intraoperative complications, and total robotic operative time. The cases were completed successfully without conversion. There were no accidental punctures or lacerations. The robotic operative times were 197 and 202 min. In this preclinical model, robotic radical perineal cystoprostatectomy and ePLND was feasible using the SP1098 robotic platform. Further investigation is needed to assess the feasibility of urinary diversion using this novel approach and new technology. © 2017 The Authors BJU International © 2017 BJU International Published by John Wiley & Sons Ltd.

Radical Cystectomy with a creation of an uro-stoma is first line treatment in advanced bladder-cancer. Enhancing or maintaining an individual's condition, skills and physical wellbeing before surgery has been defined as prehabilitation. Whether preoperative stoma-education is an effective element in prehabilitation is yet to be documented. In a prospective randomized controlled design (RCT) the aim was to investigate the efficacy of a standardised preoperative stoma-education program on an individual's ability to independently change a stoma-appliance. A parent RCT-study investigated the efficacy of a multidisciplinary rehabilitation program on length of stay following cystectomy. A total of 107 patients were included in the intension-to-treat-population. Preoperatively, the intervention-group was instructed to a standardized stoma-education program consisting of areas recognized necessary to change a stoma appliance. The Urostomy Education Scale was used to measure stoma self-care at day 35, 120 and 365 postoperatively. Efficacy was expressed as a positive difference in UES-score between treatment-groups. A significant difference in mean score was found in the intervention group compared to standard of 2.7 (95% CI: 0.9; 4.5), 4.3 (95% CI: 2.1; 6.5) and 5.1 (95% CI: 2.3; 7.8) at day 35, 120 and 365 postoperatively. For the first time a study in a RCT-design have reported a positive efficacy of a short-term preoperative stoma intervention. Preoperative stoma-education is an effective intervention and adds to the evidence base of prehabilitation. Further RCT-studies powered with self-efficacy as the primer outcome are requested.

Full Text Available We conducted this study to report on our initial experience and assess the safety, feasibility, and efficacy of extraperitoneal single plus one port laparoscopic radical prostatectomy (SPOPL-RP, and determine whether it shows any objective advantage over standard laparoscopic radical prostatectomy. From June 2009 to September 2011, 15 extraperitoneal SPOPL-RPs were performed through a 2–3-cm subumbilical longitudinal incision and another 5-mm trocar placed at the McBurney point. This cohort was compared with 37 contemporary patients who underwent standard extraperitoneal laparoscopic radical prostatectomy performed by the same urologist. Peri- and postoperative outcomes, including continence, potency, and scar length, were statistically analyzed. The two groups were comparable with respect to patient demographics, estimated blood loss, drainage time, duration of catheterization, catheterization rate >14 days, complication rate, postoperative hospitalization, and postoperative functional and oncologic outcomes (p > 0.05. The SPOPL-RP procedures had a longer mean operative time (170.1 minutes vs. 139.5 minutes, p = 0.005, but with fewer patients requiring analgesics (20% vs. 54.1%, p = 0.038 and earlier resumption of oral intake (20.7 hours vs. 26.8 hours, p = 0.037. The mean scar length in the SPOPL-RP group was much smaller (3.4 cm vs. 5.8 cm, p = 0.000 owing to the significant reduction of the skin incision. The peri- and postoperative outcomes of SPOPL-RP for low-risk prostate cancer are comparable to those with the standard laparoscopic approach. In addition, SPOPL-RP provides better postoperative pain control, faster recovery of bowel function, and smaller scar length than standard laparoscopy, albeit with a longer operative time.

Radical cystectomy (RC) is a morbid procedure with frequent complications that may benefit from implementation of an enhanced recovery after surgery (ERAS) protocol. To examine the benefits of a multimodal analgesic plan that uses continuous transversus abdominis plane (TAP) blockade as part of an ERAS protocol after RC. A retrospective comparison of consecutive patients undergoing RC over a 4-year period was conducted. Patients were designated as having surgery either before or after implementation of an ERAS protocol. A major component of the ERAS protocol was a multi-modal analgesia plan with TAP blockade. Patient demographics, comorbidities, operative details, and outcomes, including days to flatus, bowel movement (BM), narcotic usage, and length of stay (LOS) were compared. In total, 171 patients were included: 100 pre-ERAS and 71 ERAS. There were no differences in age, smoking status, operative approach, or diversion type. The patients in the ERAS cohort were less likely to be male, had a higher median BMI, and more likely to have received neoadjuvant chemotherapy. Total and early postoperative narcotic use were lower in the ERAS cohort: 89 vs. 336 mg ( p  RC pain management.

To evaluate the effect of a smoking-, alcohol- or combined-cessation intervention starting shortly before surgery and lasting 6 weeks on overall complications after radical cystectomy. Secondary objectives are to examine the effect on types and grades of complications, smoking cessation and alcohol cessation, length of hospital stay, health-related quality of life and return to work or habitual level of activity up to 12 months postoperatively. The study is a multi-institutional randomised clinical trial involving 110 patients with a risky alcohol intake and daily smoking who are scheduled for radical cystectomy. Patients will be randomised to the 6-week Gold Standard Programme (GSP) or treatment as usual (control). The GSP combines patient education and pharmacologic strategies. Smoking and alcohol intake is biochemically validated (blood, urine and breath tests) at the weekly meetings and at follow-up. Herein, we report the design of the STOP-OP study, objectives and accrual up-date. This study will provide new knowledge about how to prevent smoking and alcohol-related postoperative complications at the time of bladder cancer surgery. Till now 77 patients have been enrolled. Patient accrual is expected to be finalised before the end of 2017 and data will be published in 2018. ClinicalTrials.gov, ID: NCT02188446 . Registered on 28 May 2014.

To provide unencumbered real-time ultrasound image guidance during robot-assisted laparoscopic radical prostatectomy, we developed a robotic transrectal ultrasound system that tracks the da Vinci® Surgical System instruments. We describe our initial clinical experience with this system. After an evaluation in a canine model, 20 patients were enrolled in the study. During each procedure the transrectal ultrasound transducer was manually positioned using a brachytherapy stabilizer to provide good imaging of the prostate. Then the transrectal ultrasound was registered to the da Vinci robot by a previously validated procedure. Finally, automatic rotation of the transrectal ultrasound was enabled such that the transrectal ultrasound imaging plane safely tracked the tip of the da Vinci instrument controlled by the surgeon, while real-time transrectal ultrasound images were relayed to the surgeon at the da Vinci console. Tracking was activated during all critical stages of the surgery. The transrectal ultrasound robot was easy to set up and use, adding 7 minutes (range 5 to 14) to the procedure. It did not require an assistant or additional control devices. Qualitative feedback was acquired from the surgeons, who found transrectal ultrasound useful in identifying the urethra while passing the dorsal venous complex suture, defining the prostate-bladder interface during bladder neck dissection, identifying the seminal vesicles and their location with respect to the rectal wall, and identifying the distal prostate boundary at the apex. Real-time, registered robotic transrectal ultrasound guidance with automatic instrument tracking during robot-assisted laparoscopic radical prostatectomy is feasible and potentially useful. The results justify further studies to establish whether the approach can improve procedure outcomes. Copyright © 2015 American Urological Association Education and Research, Inc.

We aimed to assess contemporary rates of neoadjuvant chemotherapy (NC) use. We relied on the Surveillance, Epidemiology and End Results (SEER)-Medicare database for non-metastatic, muscle-invasive (T2-T4a) urothelial carcinoma of the urinary bladder (UCUB) patients who underwent radical cystectomy (RC) between 1991 and 2009. Multivariable logistic regression analyses tested predictors of NC use, such as: T-stage, N-stage, year of diagnosis, age at diagnosis, gender, race, use of radiotherapy (RT), marital status, urban status, socioeconomic status, tumour grade, and Charlson comorbidity index (CCI). Overall, 5207 patients treated with RC were identified. Of those, 332 (6.4%) received NC. The rate of NC increased over time from 6.1% (1991) to 15.0% (2009) (pvs. T2: OR: 0.7; p=0.003), married status (OR: 1.5; p=0.006), and younger age at diagnosis (≥80 vs. 66-69: OR: 0.6; p=0.006) were associated with a higher odds of NC; all represented independent predictors of NC use. Neither race nor CCI demonstrated statistical significance. We reported lower than anticipated overall (6.4%) use of NC. Nonetheless, the rate increased from 6.1% (1991) to 15.0% (2009). Older and unmarried individuals were less likely to receive NC. NC rates were higher in T2 UCUB patients. Some of the observed discrepancies, such as lower use in unmarried individuals, may require correction. Better adherence to guidelines should be encouraged and implemented, especially based on the confirmed benefits of NC according to randomized, controlled trials. The study is limited by a retrospective design and limited variables.

Health-Related Quality of Life after Cystectomy and Urinary Diversion for Bladder Cancer

Shih, Cheryl; Porter, Michael P.

2011-01-01

With multiple options for urinary diversion after radical cystectomy for bladder cancer that have comparable cancer control and complication rates, health-related quality of life (HRQOL) has become an important consideration. This article reviews the methods for defining HRQOL, the challenges in measuring HRQOL in bladder cancer, and the literature comparing HRQOL after various methods of urinary diversion. Recent contributions include the validation of HRQOL instruments specific to bladder cancer and the publication of several prospective studies measuring HRQOL outcomes after cystectomy and urinary diversion. There is no convincing evidence from existing literature that any particular method of urinary diversion offers superior HRQOL outcomes. Rather, there is growing evidence that good HRQOL can be achieved with patient education and consideration of each patient's clinical and psychosocial situation. Future research should utilize the validated bladder cancer specific HRQOL instruments and perhaps explore the impact of preoperative counseling on postoperative HRQOL. PMID:21826139

Laparoscopic radical nephroureterectomy: dilemma of the distal ureter.

Science.gov (United States)

Steinberg, Jordan R; Matin, Surena F

2004-03-01

Laparoscopic nephroureterectomy has recently emerged as a safe, minimally invasive approach to upper tract urothelial cancers. The most controversial and challenging feature of laparoscopic nephroureterectomy is the management of the distal ureter. We review the most common methods of managing the distal ureter, with emphasis on contemporary oncologic outcomes, indications, advantages, and disadvantages. There are currently in excess of five different approaches to the lower ureter. These techniques often combine features of endoscopic, laparoscopic, or open management. They include open excision, a transvesical laparoscopic detachment and ligation technique, laparoscopic stapling of the distal ureter and bladder cuff, the "pluck" technique, and ureteral intussusception. Each technique has distinct advantages and disadvantages, differing not only in technical approach, but oncological principles as well. While the existing published data do not overwhelmingly support one approach over the others, the open approach remains one of the most reliable and oncologically sound procedures. The principles of surgical oncology dictate that a complete, en-bloc resection, with avoidance of tumor seeding, remains the preferred treatment of all urothelial cancers. The classical open technique of securing the distal ureter and bladder cuff achieves this principle and has withstood the test of time. Transvesical laparoscopic detachment and ligation is an oncologically valid approach in patients without bladder tumors, but is limited by technical considerations. The laparoscopic stapling technique maintains a closed system but risks leaving behind ureteral and bladder cuff segments. Both transurethral resection of the ureteral orifice (pluck) and intussusception techniques should be approached with caution, as the potential for tumor seeding exists. Additional long-term comparative outcomes are needed to solve the dilemma of the distal ureter.

Full Text Available Aims: To compare laparoscopic radical nephrectomy (LRN with open radical nephrectomy (ORN in T1-T3 renal lesions. Materials and Methods: The records of 65 patients who underwent LRN between January 2002 and December 2006 were entered prospectively in a database. The patients were compared with 56 patients who had undergone ORN between January 2000 and December 2005. The two groups were comparable in terms of age, body mass index (BMI and tumor size. LRN was compared with ORN in terms of operative room time, blood loss, complications , analgesic requirement, hospital stay and start of oral intake. The oncologic efficacy was evaluated in stages T1 and T2 in terms of cancer-free and overall survival. Results: The laparoscopy group had a significantly shorter hospital stay (5.72, range 3-23 days vs. 9.18, range 4-23 days, p value: < 0.0001, analgesia requirement (175.65, range 50-550 mg vs. 236, range 0-1100 mg of tramadol, p value: < 0.03, hemoglobin decline (1.55, range 0.1 to 4.4 mg/dl vs. 2.25, range 0.2 - 7 mg/dL, p value: < 0.001 and hematocrit drop (4.83, range 0.3 - 12.9 vs. 7.06 range 2 -18, p value: < 0.0001. The majority of specimens showed renal cell carcinoma. In the laparoscopy group, 29 tumors were T1 stage, 18 were T2, while eight were T3. In the open surgery group, 25 tumors were T1, 19 were T2 and 12 were T3. The cancer-free survival rate at 24 months for ORN and LRN in T1 lesions was 91.7% and 93.15% respectively and the patient survival rate was 100% in both groups. The cancer-free survival rate at 24 months for ORN and LRN in T2 lesions was 88.9% and 94.1%, respectively and the patient survival was 100% and 94%, respectively. After LRN, there was one instance of port site metastasis, local recurrence and distant metastasis. All recurrences were distant after ORN. Conclusion: Laparoscopic radical nephrectomy has advantages in terms of shorter hospitalization and a lower analgesia requirement. It is feasible and produces effective

Aim: We aim to evaluate the National Cancer Institute (NCI) treatment protocol and its outcome regarding recurrence, progression and survival in patients with T1G3 urinary bladder transitional cell carcinoma. Patients and Methods: In a retrospective study, between January 2001 and December 2007, all 34 patients with T1G3 bladder transitional cell carcinoma (TCC), after complete transurethral resection (TURBT), received intravesical BCG as adjuvant therapy. A conservative approach was adopted, whereby those with superficial recurrences were eligible to TURBT, with delayed cystectomy for progression to muscle invasion. Overall, recurrence, and progression-free survival were analyzed. Results: Thirty-three patients were included, 29 were males and 4 were females. The mean age was 61 years (range 35-89 years). Final analysis was made at median follow-up of 15 months (Range of 3-68 months, mean 18 months) for survival. Eleven (33.3%) patients had multi- focal tumors. Associated schistosomiasis was present in 12 (36.6%) patients. Twenty-two (66.67%) patients showed recurrence. Eleven out of these 22 (50.0%) patients progressed to muscle invasion and underwent radical cystectomy. Ten out of 34 (30.3%) patients received post- cystectomy radiotherapy. Two (20.0%) of them, were staged as TNM stage II, 6 (60.0%) as TNM stage III and 2 (20.0%) patients were TNM stage IV. Eight (72.7%) of these 11 patients had post-cystectomy radiotherapy alone; while the 2 (6.0%) other patients with stage IV had adjuvant concomitant Cisplatin and Gemcitabine chemotherapy. Five (14%) patients of those cystectomy patients died of TCC. Three (60%) patients died from metastatic disease (to lung, liver and bone), one patient died from advanced locoregional disease and another patient died from post- operative complications. Among those patients who received radiotherapy alone, 62.5% are alive. Although, we report a biologically more aggressive behavior of T1G3 than that reported by some authors

To reduce short-term complications of radical cystectomy (RC) and intestinal urinary diversion with vescica ileale Padovana (VIP) neobladder, we described and assessed an enhanced recovery protocol (ERP) in a series of consecutive patients. An ERP was introduced focusing on reduced bowel preparation, standardized feeding and analgesic regimens. We analyzed the outcomes with all patients consecutively undergoing RC and VIP neobladder who met the following inclusion criteria: American Society of Anesthesiologists score Short Form criteria; absence of inflammatory bowel diseases. Thirty-one consecutive patients were recruited to undergo our ERP. Mean age of patients was 62.16 years. No patients died due to surgical complications. Nine of 31 patients experienced complications (29.03%), none requiring surgical intervention. According to Clavien grading, all complications were grade <2. The application of our ERP to our patients undergoing RC and VIP neobladder contributed to reduce postoperative morbidity. Copyright © 2013 S. Karger AG, Basel.

The purpose of the study was to compare laparoscopic total radical hysterectomy with classic radical hysterectomy regarding parametrial, and vaginal resection, and lymphadenectomy. Laparoscopic or laparotomic total radical hysterectomy with advantages and disadvantages was offered to the patients diagnosed as having operable cervical cancer between 2007 and 2010. Lymph node status, resection of the parametria and vagina, and margin positivity were recorded for both groups. Data were collected prospectively. Statistical analysis was performed with the SPSS statistical software program. Totally, 53 cases had classical abdominal radical hysterectomy and 35 laparoscopic radical hysterectomy, respectively. Parametrial involvement was detected in four (11.4%) cases in laparoscopic radical surgery versus nine (16.9%) in laparatomic surgery. All the cases with parametrial involvement had free surgical margins of tumor. Also there were no significant statistical differences in lymph node number and metastasis between the two groups. There is no difference in anatomical considerations between laparoscopic and laparatomic radical surgery in the surgical management of cervical cancer.

Fifty-three consecutive unselected patients with invasive bladder cancer, Stage T2 to T3, treated by radical radiotherapy have been reviewed. Cystectomy was reserved for patients with significant worsening of disease during treatment, histologically confirmed persistent or recurrent invasive tumour after treatment, or patients with intolerable symptoms due to radiation cystitis. In 64% of our patients a favourable tumour response to radiotherapy was seen, while a further 31% showed disease progression either during or on completion of radiotherapy. Cystectomy was performed on 22% of patients, mainly for radiation cystitis, and was not associated with a significant operative mortality rate. The crude 5-year survival rate was 42%. We conclude that radical radiotherapy is as effective as other forms of treatment for invasive bladder cancer, but that there remains a need to identify those bladder tumours destined to respond poorly to radiotherapy at an earlier stage.

The surgical treatment of endometrial cancer is still a matter of debate. Two of the most controversial issues are the beneficial effect of lymphadenectomy and the feasibility of laparoscopy. The aim of the case report was to describe the feasibility of total laparoscopic radical hysterectomy with pelvic lymphadenectomy in a 56-years-old Caucasian woman diagnosed with endometrial cancer. After a CO2 pneumoperitoneum was created the peritoneum was incised cranially to the para-colic fossa just above the external iliac vessels until the psoas muscle is visualized. The external iliac vessels were identified and lymph nodes from the anterior and the medial surface were removed until the iliac bifurcation and placed in an Endo-bag. The procedure continued with the identification of the hypo-gastric and the umbilical artery which were pulled medially in order to open the obturator fossa and remove the lymphatic tissue superior to the obturator nerve. The next step was the opening of the para-vesical and pararectal spaces by using blunt dissection; this maneuver was facilitated by pulling the uterine fundus towards the opposite direction with the uterine manipulator. The parametrium being isolated between the two spaces can be safely divided. At the superior limit of the parametrium the uterine artery is identified and divided at its origin. Thereafter, by placing the uterine fundus in median and posterior position, the vesicouterine peritoneal fold was opened by scissors and a bladder dissection from the low uterine segment down to the vagina was performed. Then the ureter is dissected, freed from its attachments to the parametria and de-crossed from the uterine artery down to its entry into the bladder. Next the rectovaginal space is opened and the utero-sacral ligaments divided; this allows the division of para-vaginal attachments. The vagina is sectioned and the specimen is extracted transvaginally. Then the vaginal stump was sutured by laparoscopy. Total laparoscopic

Bladder cancer (BC) is the ninth most common cancer worldwide. Radical cystectomy (RC) with neoadjuvant chemotherapy (NAC) is recommended for muscle-invasive BC. The challenge of the neoadjuvant approach relates to challenges in selection of patients to chemotherapy that are likely to respond to the treatment. To date, there are no validated molecular markers or baseline clinical characteristics to identify these patients. Different inflammatory markers, including tumor associated macrophages with their plastic pro-tumorigenic and anti-tumorigenic functions, have extensively been under interests as potential prognostic and predictive biomarkers in different cancer types. In this immunohistochemical study we evaluated the predictive roles of three immunological markers, CD68, MAC387, and CLEVER-1, in response to NAC and outcome of BC. 41% of the patients had a complete response (pT0N0) to NAC. Basic clinicopathological variables did not predict response to NAC. In contrast, MAC387 + cells and CLEVER-1 + macrophages associated with poor NAC response, while CLEVER-1 + vessels associated with more favourable response to NAC. Higher counts of CLEVER-1 + macrophages associated with poorer overall survival and CD68 + macrophages seem to have an independent prognostic value in BC patients treated with NAC. Our findings point out that CD68, MAC387, and CLEVER-1 may be useful prognostic and predictive markers in BC.

To evaluate the alterations on surgical outcomes after of the implementation of 3D laparoscopic technology for the surgical treatment of early-stage cervical carcinoma. Data of patients undergoing type B radical hysterectomy (with or without bilateral salpingo-oophorectomy) and pelvic lymphadenectomy via 3D laparoscopy were compared with a historical cohort of patients undergoing type B radical hysterectomy via conventional laparoscopy. Complications (within 60 days) were graded per the Accordion severity system. Data of 75 patients were studied: 15 (20%) and 60 (80%) patients undergoing surgery via 3D laparoscopy and conventional laparoscopy, respectively. Baseline patient characteristics as well as pathologic findings were similar between groups (p>0.1). Patients undergoing 3D laparoscopy experienced a trend toward shorter operative time than patients undergoing conventional laparoscopy (176.7 ± 74.6 vs 215.9 ± 61.6 minutes; p = 0.09). Similarly, patients undergoing 3D laparoscopic radical hysterectomy experienced shorter length of hospital stay (2 days, range 2-6, vs 4 days, range 3-11; p<0.001) in comparison to patients in the control group, while no difference in estimated blood loss was observed (p = 0.88). No between-group difference in complication rate was observed. 3D technology is a safe and effective way to perform type B radical hysterectomy and pelvic node dissection in early-stage cervical cancer. Further large prospective studies are warranted in order to assess the cost-effectiveness of the introduction of 3D technology in comparison to robotic assisted surgery.

Neoadjuvant chemotherapy in pure urothelial bladder cancer provides a significant survival benefit. However, to the authors' knowledge, it is unknown whether this benefit persists in histological variants. The objective of the current study was to assess the effect of neoadjuvant chemotherapy on the probability of non-organ-confined disease and overall survival after radical cystectomy (RC) in patients with histological variants. Querying the National Cancer Data Base, the authors identified 2018 patients with histological variants who were undergoing RC for bladder cancer between 2003 and 2012. Variants were categorized as micropapillary or sarcomatoid differentiation, squamous cell carcinoma, adenocarcinoma, neuroendocrine tumors, and other histology. Logistic regression models estimated the odds of non-organ-confined disease at the time of RC for each histological variant, stratified by the receipt of neoadjuvant chemotherapy. Cox regression models were used to examine the effect of neoadjuvant chemotherapy on overall mortality in each variant subgroup. Patients with neuroendocrine tumors (odds ratio [OR], 0.16; 95% confidence interval [95% CI], 0.08-0.32 [Pchemotherapy. An overall survival benefit for neoadjuvant chemotherapy was only found in patients with neuroendocrine tumors (hazard ratio, 0.49; 95% CI, 0.33-0.74 [P=.001]). Patients with neuroendocrine tumors benefit from neoadjuvant chemotherapy, as evidenced by better overall survival and lower rates of non-organ-confined disease at the time of RC. For tumors with micropapillary differentiation, sarcomatoid differentiation, or adenocarcinoma, neoadjuvant chemotherapy decreased the frequency of non-organ-confined disease at the time of RC. However, this favorable effect did not translate into a statistically significant overall survival benefit for these patients, potentially due to the aggressive tumor biology.

To examine the impact of tamsulosin on the rate of acute urinary retention following early catheter removal after robot-assisted laparoscopic radical prostatectomy. A total of 236 patients who underwent robot-assisted laparoscopic radical prostatectomy for prostate cancer carried out by a single surgeon were enrolled in this randomized study. Patients were randomly divided into two groups: treatment with tamsulosin (0.4 mg) from 1 day before to 14 days after surgery (tamsulosin group), or no tamsulosin treatment (control group). The urethral catheter was removed on the fifth postoperative day. The primary end-point was the acute urinary retention rate. Changes in each domain of the International Continence Society male short-form questionnaire and uroflowmetry parameters were secondary end-points. The primary end-point was assessed in 218 patients (92.4%; n = 109 in each group). It was not assessed in 18 patients because of cystographic leak from the vesicourethral anastomosis. The acute urinary retention rate was lower in the tamsulosin group (7.3%) than in the control group (17.4%, P = 0.018). Multivariate logistic regression analysis identified tamsulosin treatment and the operative experience of the surgeon as independent risk factors for acute urinary retention. Tamsulosin-treated patients had a 0.30-fold lower risk of developing acute urinary retention compared with control patients (95% confidence interval 0.12-0.76; P = 0.011). None of the International Continence Society male questionnaire domain scores showed significant changes between the groups. Perioperative treatment with tamsulosin in patients undergoing robot-assisted laparoscopic radical prostatectomy reduces the rate of acute urinary retention after early catheter removal, without aggravating urinary incontinence. © 2013 The Japanese Urological Association.

Peritoneal Dialysis and Retroperitoneal Laparoscopic Radical Nephrectomy: A Favorable Experience With a Patient Complicated by Renal Cell Carcinoma

Directory of Open Access Journals (Sweden)

2017-12-01

Full Text Available Peritoneal dialysis (PD is an accepted modality for managing end-stage kidney disease. We herein report a 75-year-old female patient on chronic PD who was complicated by renal cell carcinoma. She was successfully treated with retroperitoneal laparoscopic radical nephrectomy followed by a prompt resumption of the procedure. Various surgeries disturbing the abdominal wall integrity often disrupt the regular PD schedule, and using minimally invasive approaches is therefore an attractive therapeutic option. Our experience emphasizes the feasibility and safety of a retroperitoneal approach–based laparoscopic technique based on several empirical examples. However, systemic studies on this topic are obviously lacking, so we strongly recommend the accumulation of more cases similar to our own. Several surgical concerns that need to be dealt with among PD patients are also discussed.

In recent years the progress of laparoscopic procedures and the development of new and dedicated technologies have made laparoscopic hepatic surgery feasible and safe. In spite of this laparoscopic liver resection remains a surgical procedure of great challenge because of the risk of massive bleeding during liver transection and the complicated biliary and vascular anatomy in the liver. A new laparoscopic device is reported here to assist liver resection laparoscopically. The laparoscopic Habib 4X is a bipolar radiofrequency device consisting of a 2 x 2 array of needles arranged in a rectangle. It is introduced perpendicularly into the liver, along the intended transection line. It produces coagulative necrosis of the liver parenchyma sealing biliary radicals and blood vessels and enables bloodless transection of the liver parenchyma. Twenty-four Laparoscopic liver resections were performed with LH4X out of a total of 28 attempted resections over 12 months. Pringle manoeuvre was not used in any of the patients. None of the patients required intraoperative transfusion of red cells or blood products. Laparoscopic liver resection can be safely performed with laparoscopic Habib 4X with a significantly low risk of intraoperative bleeding or postoperative complications.

Objective: To evaluate the application value of carbon lymph node tracing technique by preoperative endoscopic subserosal injection in laparoscopic radical gastrectomy. Methods: From June 2013 to February 2015, seventy eight patients with gastric cancer were enrolled and randomly divided into trial group and control group. Subserosal injection of carbon nanoparticles around the tumor was performed by preoperative endoscopic subserosal injection one day before the operation in trial group, while the patients routinely underwent laparoscopic gastrectomy in control group. Results of harvested lymph nodes, postoperative complications were compared between the two groups. Carbon nanoparticle-related side effect was also evaluated. Results: The average number of harvested lymph node in trial group was significantly higher than that in control group (35.5±8.5 vs 29.5±6.5, P 0.05), and no carbon nanoparticle-related side effect was observed. Conclusion: Given a higher harvested lymph node number and a similar rate of complications, preoperative endoscopic subserosal injection of carbon nanoparticles was safe and feasible.

Morbidity and postoperative pain after extraperitoneal (E-LRPE) and transperitoneal (T-LRPE) laparoscopic radical prostatectomy was compared to open extraperitoneal radical prostatectomy (O-RPE). Between January 2002 and October 2003, we evaluated 41 E-LRPE, 39 T-LRPE and 41 O-RPE prospectively. All operations were performed as standard procedures by the same group of surgeons and perioperative results and complications were evaluated. Pain management was performed with tramadol 50-100 mg on demand, and no other form of anaesthesia was given. Postoperative pain was assessed daily in all patients quantifying analgesic requirement and evaluation of Visual Analogue Scale (VAS). All patients had at least a 12 month follow-up. Mean age, prostate volume, PSA and Gleason score were comparable between all three groups (p>0.05). Mean blood loss was lower with laparoscopy (189+/-140 and 290+/-254 ml), as compared to 385+/-410 ml for O-RPE (p=0.002). However, mean operating times were significantly longer in L-TRPE (279+/-70 min) as compared to E-LRPE (217+/-51 min) and O-RPE (195+/-72 min) (ppain (p=0.029) in all groups, especially for T-LRPE (p=0.007). Likewise, increased operating times (>240 min) were associated with increased post-operative pain (p=0.049). Full continence defined as no pads at one year was achieved in 36/41 (88%, E-LRPE) versus 33/39 (85%, T-LRPE) versus 33/41 (81%, O-RPE), respectively (p=0.2). E-LRPE resulted in a significant subjective (VAS Score, ppain reduction compared to T-LRPE, but only in VAS Score compared to O-RPE (p=0.008). Analgetic consumption during first postoperative week was equal in E-LRPE (290 mg) and O-RPE (300 mg) (p=0.550). Shorter operating times, lower urinary leakage rates, lower stricture rates and lower blood loss in E-LRPE compared to T-LRPE are mainly explained due to the long learning curve in LRPE, which we did not overcome yet, and not due to the approach (extraperitoneal versus transperitoneal).

To identify predictive factors underlying recurrence and survival after partial cystectomy for pelvic lymph node-negative muscle-invasive bladder cancer (MIBC) (urothelial carcinoma) and to report the results of partial cystectomy among select patients. We retrospectively reviewed 101 cases that received partial cystectomy for MIBC (pT2-3N0M0) between 2000 and 2010. The log-rank test and a Cox regression analyses were performed to identify factors that were predictive of recurrence and survival. With a median follow-up of 53.0 months (range 9-120), the 5-year overall survival (OS), cancer-specific survival (CSS) and recurrence-free survival (RFS) rates were 58%, 65% and 50%, respectively. A total of 33 patients died of bladder cancer and 52 patients survived with intact bladder. Of the 101 patients included, 55 had no recurrence, 12 had non-muscle-invasive recurrence in the bladder that was treated successfully, and 34 had recurrence with advanced disease. The multivariate analysis showed that prior history of urothelial carcinoma (PH.UC) was associated with both CSS and RFS and weakly associated with OS; lymphovascular invasion (LVI) and ureteral reimplantation (UR) were associated with OS, CSS and RFS. Among patients with pelvic lymph node-negative MIBC, PH.UC and UR should be considered as contraindications for partial cystectomy, and LVI is predictive of poor outcomes after partial cystectomy. Highly selective partial cystectomy is a rational alternative to radical cystectomy for the treatment of MIBC with negative pelvic lymph nodes. Copyright © 2013 Elsevier Ltd. All rights reserved.

It is considered that laparoscopic single-site surgery should be performed by specially trained surgeons because of the technical difficulty in using special instruments through limited access. We investigated suitable patients for single-port laparoscopic radical nephrectomy, focusing on the anatomy and distribution of the renal artery and vein. This retrospective study was conducted in 52 consecutive patients who underwent single-port radical nephrectomy by the transperitoneal approach. In patients undergoing right nephrectomy, a 2-mm port was added for liver retraction. We retrospectively re-evaluated all of the recorded surgical videos and preoperative computed tomography images. The pneumoperitoneum time (PT) was used as an objective index of surgical difficulty. The PT was significantly shorter for right nephrectomy than left nephrectomy (94 vs. 123 min, P = 0.004). With left nephrectomy, dissection of the spleno-renal ligament to mobilize the spleen medially required additional time. Also, the left renal vein could only be divided after securing the adrenal, gonadal and lumbar veins. In patients whose renal artery was located cranial to the renal vein, PT tended to be longer than in the other patients (131 vs. 108 min, P = 0.070). In patients with a superior renal artery, the inferior renal vein invariably covered the artery and made it difficult to ligate the renal artery via the umbilical approach at the first procedure. These findings indicate that patients undergoing right nephrectomy in whom the renal artery is not located cranial to the renal vein are suitable for single-port laparoscopic radical nephrectomy. © The Author 2017.

David Canes

2008-03-01

Full Text Available PURPOSE: Our goal was to assess outcomes of a selective drain placement strategy during laparoscopic radical prostatectomy (LRP with a running urethrovesical anastomosis (RUVA using cystographic imaging in all patients. Materials and Methods: A retrospective chart review was performed for all patients undergoing LRP between January 2003 and December 2004. The anastomosis was performed using a modified van Velthoven technique. A drain was placed at the discretion of the senior surgeon when a urinary leak was demonstrated with bladder irrigation, clinical suspicion for a urinary leak was high, or a complex bladder neck reconstruction was performed. Routine postoperative cystograms were obtained. RESULTS: 208 patients underwent LRP with a RUVA. Data including cystogram was available for 206 patients. The overall rate of cystographic urine leak was 5.8%. A drain was placed in 51 patients. Of these, 8 (15.6% had a postoperative leak on cystogram. Of the 157 undrained patients, urine leak was radiographically visible in 4 (2.5%. The higher leak rate in the drained vs. undrained cohort was statistically significant (p = 0.002. Twenty-four patients underwent pelvic lymph node dissection (8 drained, 16 undrained. Three undrained patients developed lymphoceles, which presented clinically on average 3 weeks postoperatively. There were no urinomas or hematomas in either group. CONCLUSIONS: Routine placement of a pelvic drain after LRP with a RUVA is not necessary, unless the anastomotic integrity is suboptimal intraoperatively. Experienced clinical judgment is essential and accurate in identifying patients at risk for postoperative leakage. When suspicion is low, omitting a drain does not increase morbidity.

In radical cystectomy, the surgeon generally ligates the umbilical artery at its origin. This artery may give rise to several arteries that supply the sexual organs. Our aim was to evaluate pelvic and perineal devascularisation in women after total cystectomy. We carried out a prospective anatomical and radiological study. We performed bilateral pelvic dissections of fresh adult female cadavers to identify the dividing branches of the umbilical artery. In parallel, we examined and compared the pre- and postoperative imaging investigations [magnetic resonance imaging (MRI) angiography] in patients undergoing cystectomy for benign disease to quantify the loss of pelvic vascularisation on the postoperative images by identifying the occluded arteries. The anatomical study together with the radiological study visualised 35 umbilical arteries (n = 70) with their branching patterns and collateral arteries. The uterine artery originated from the umbilical artery in more than 75% of cases (n = 54) of the internal pudendal artery in 34% (n = 24) and the vaginal artery in 43% (n = 30). The postoperative MRI angiograms showed pelvic devascularisation in four patients. Devascularisation was dependent on the level of surgical ligation. In the four patients with loss of pelvic vascular supply, the umbilical artery had been ligated at its origin. The umbilical artery gives rise to various branches that supply the pelvis and perineum. If the surgeon ligates the umbilical artery at its origin during total cystectomy, there is a significant risk of pelvic and perineal devascularisation.

Perioperative Blood Transfusion Promotes Worse Outcomes of Bladder Cancer after Radical Cystectomy: A Systematic Review and Meta-Analysis.

Full Text Available Multiple studies have investigated the effect of perioperative blood transfusion (PBT for patients with radical cystectomy (RC, but the results have been inconsistent. We conducted a systematic review and meta-analysis to investigate the relationship between PBT and the clinical outcomes of RC patients.We searched MEDLINE, EMBASE, the Cochrane library and BIOSIS previews to identify relevant literature for studies that focused on the relationship of PBT and outcomes of patients undergoing RC. A fixed or random effects model was used in this meta-analysis to calculate the pooled hazard ratio (HR with 95% confidence intervals (CIs.A total of 7080 patients in 6 studies matched the selection criteria. Aggregation of the data suggested that PBT in patients who underwent RC correlated with increased all-cause mortality, cancer-specific mortality and cancer recurrence. The combined HRs were 1.19 (n = 6 studies, 95% CI: 1.11-1.27, Z = 4.71, P<0.00001, 1.17 (n = 4 studies, 95% CI: 1.06-1.30, Z = 3.06, P = 0.002, 1.14 (n = 3 studies, 95% CI: 1.03-1.27, Z = 2.50, P = 0.01, respectively. The all-cause mortality associated with PBT did not vary by the characteristics of the study, including number of study participants, follow-up period and the median blood transfusion ratio of the study.Our data showed that PBT significantly increased the risks of all-cause mortality, cancer-specific mortality and cancer recurrence in patients undergoing RC for bladder cancer.

The purpose of this study is to compare and evaluate the security and efficacy of 3D vs 2D laparoscopy in rectal cancer treatment. Forty-six patients who suffered from rectal cancer and went on laparoscopic radical resection of rectal carcinoma in Peking University Shougang Hospital from Feb. 2015 to Mar. 2016 were included in the study. They were randomly divided into two groups. The 23 patients operated with the 3D system were compared with 23 patients operated with the 2D system by perioperative data. There were no significant differences in age, sex, pathological type, tumor differentiation, TNM staging, and surgical procedures (P > 0.05). The average operating time of 3D laparoscopic surgery group (172.2 ± 27.5 min) was shorter than that of 2D group (192.6 ± 22.3) (P  0.05) were not significantly different. There were no differences in other complications between the two groups. No significantly different recrudescence and death rates were found between the two groups (P > 0.05). The 3D laparoscopy shortens the operation time of rectum cancer. 3D laparoscopic surgery is more efficient in treatment of rectal cancer than 2D laparoscopy and is worth of being generalized.

Laparoscopic resection of hilar cholangiocarcinoma is technically challenging because it involves complicated laparoscopic procedures that include laparoscopic hepatoduodenal lymphadenectomy, hemihepatectomy with caudate lobectomy, and hepaticojejunostomy. There are currently very few reports describing this type of surgery. Between August 2014 and December 2014, 5 patients underwent total laparoscopic or laparoscopic-assisted surgery for hilar cholangiocarcinoma. Two patients with type I or II hilar cholangiocarcinoma underwent radical hilar resection. Three patients with type IIIa or IIIb cholangiocarcinoma underwent extended hemihepatectomy together with caudate lobectomy. The median (range) age, operation time, blood loss, and length of hospital stay were 63 years (43-76 years), 610 minutes (410-665 minutes), 650 mL (450-1,300 mL), and 12 days (9-21 days), respectively. Four patients had a negative margin, but 1 patient was diagnosed with high-grade dysplasia on the proximal resection margin. The median tumor size was 3.0 cm. One patient experienced postoperative biliary leakage, which resolved spontaneously. Laparoscopic resection is a feasible surgical approach in selected patients with hilar cholangiocarcinoma.

Acquisition of the da Vinci surgical system (Intuitive Surgical, Mountain View, USA) has enabled robot-assisted surgery to become an acceptable alternative to open radical prostatectomy (ORP). Implementation of robotics at a single institution in Korea induced a gradual increase in the number of performances of robot-assisted laparoscopic radical prostatectomy (RALP) to surgically treat localized prostate cancer. We analyzed the impact of robotic instrumentation on practice patterns among urologists and explain the change in value in ORP and RALP-the standard treatment and the new approach or innovation of robotic technology. The overall number of prostatectomies has increased over time because the number of RALPs has grown drastically whereas the number of OPRs did not decrease during the period of evaluation. Our experience emphasizes the potential of RALP to become the gold standard in the treatment of localized prostate cancer in various parts of the world.

To assess the prevalence of preoperative anemia and the impact of preoperative anemia and blood transfusion requirement on 30- and 90-day complications in a cohort of patients undergoing robot-assisted radical cystectomy with intracorporeal urinary diversion (iRARC). IRARC was performed on 166 patients between June 2011 and March 2016. Prospective data were collected for patient demographics, clinical and pathologic characteristics, perioperative variables, transfusion requirements, and hospital length of stay. Thirty- and 90-day complications were classified according to the modified Memorial Sloan Kettering Cancer Center Clavien-Dindo system. Preoperative anemia was common (43.4%) and greatest in patients receiving neoadjuvant chemotherapy (48.6%) (p blood transfusion (p = 0.001). Blood transfusion required in 20.4% of patients with intraoperative and postoperative blood transfusion rate was 10.2% and 13.9%, respectively. The 30-day all complication rate and 30-day major complication rate were 55.4% and 15.7%, respectively, while 90-day all complication rate and 90-day major complication rate were 65.7% and 19.3%, respectively. Intraoperative blood transfusion was not associated with increased complications, but postoperative blood transfusion requirement was independently associated with perioperative morbidity: all 30-day complications (p = 0.003), all 90-day complications (p = 0.009), and 90-day major complications (p = 0.004). The presence of preoperative anemia in patients undergoing iRARC is not associated with increased surgical risk, although preoperative anemic patients were significantly more likely to require blood transfusion. Blood transfusion requirement and specifically postoperative blood transfusion are independently associated with perioperative morbidity and are an important factor for the optimization of postoperative outcomes.

The objective of this study was to identify nutritional preoperative factors associated with complications after radical cystectomy (RC). We prospectively evaluated the Mini-Nutritional Assessment Score, body mass index (BMI), appetite, stool frequency, hydration, food intake, weight loss, albuminemia, and prealbuminemia of 144 patients who underwent RC between January 2011 and April 2014. Postoperative complications were defined as any adverse event reported in the patient's file up to 90 days after surgery. Each complication was classified according to the Clavien-Dindo and Memorial Sloan-Kettering Cancer Center systems. The adjusted relative risk (RR) computed through a Poisson regression model was used to identify nutritional risk factors associated with post-RC complications. A high BMI >27 kg/m 2 was associated with higher risk of low-grade complications (RR:1.47 [95% CI,1.09-2.00]) at 7 days and a four-fold increased risk of cardiac complications at 7 and 90 days (RR:3.77 [1.15-12.32] and RR:3.28 [1.35-7.98]). Decreased appetite was associated with low-grade (RR:1.43 [1.03-1.99] complications within 90 days. Preoperative weight loss >3 kg was associated with high-grade (RR:2.49 [1.23-5.05]) and wound (RR:2.51 [1.23-5.10]) complications within 90 days. This study showed that preoperative nutritional status of patients may predict the occurrence of complications up to 90 days post-RC. Development of preoperative nutritional interventions may reduce the deleterious impact of RC on patients' health.

Full Text Available Purpose: To assess the effectiveness and safety of robot-assisted radical prostatectomy (RARP versus laparoscopic radical prostatectomy (LRP in the treatment of prostate cancer. Materials and Methods: Existing systematic reviews were updated to investigate the effectiveness and safety of RARP. Electronic databases, including Ovid MEDLINE, Ovid Embase, the Cochrane Library, KoreaMed, Kmbase, and others, were searched through July 2014. The quality of the selected systematic reviews was assessed by using the revised assessment of multiple systematic reviews (R-Amstar and the Cochrane Risk of Bias tool. Meta-analysis was performed by using Revman 5.2 (Cochrane Community and Comprehensive Meta-Analysis 2.0 (CMA; Biostat. Cochrane Q and I2 statistics were used to assess heterogeneity. Results: Two systematic reviews and 16 additional studies were selected from a search performed of existing systematic reviews. These included 2 randomized controlled clinical trials and 28 nonrandomized comparative studies. The risk of complications, such as injury to organs by the Clavien-Dindo classification, was lower with RARP than with LRP (relative risk [RR], 0.44; 95% confidence interval [CI], 1.23–0.85; p=0.01. The risk of urinary incontinence was lower (RR, 0.43; 95% CI, 0.31–0.60; p<0.000001 and the potency rate was significantly higher with RARP than with LRP (RR, 1.38; 95% CI, 1.11–1.70; I2 =78%; p=0.003. Regarding positive surgical margins, no significant difference in risk between the 2 groups was observed; however, the biochemical recurrence rate was lower after RARP than after LRP (RR, 0.59; 95% CI, 0.48–0.73; I2 =21%; p<0.00001. Conclusions: RARP appears to be a safe and effective technique compared with LRP with a lower complication rate, better potency, a higher continence rate, and a decreased rate of biochemical recurrence.

To review our experience in robot-assisted radical cystectomy, assessing the complications and oncological and functional results. From 2007 to 2014, we performed 67 robot-assisted radical cystectomies combined with lymphadenectomy in 61 cases. The operations were performed on 37 patients due to muscle-invasive tumours and on 30 due to high-risk nonmuscle-invasive tumours. Urinary diversion was conducted extracorporeally, using a Studer neobladder in 47 cases. The mean blood loss was 300mL. No case required conversion to open surgery. The median number of lymph nodes extracted was 16 (range 3-33). Pathology revealed 16 pT0, 15 pTis,-pT1-pTa and 44 muscle-invasive tumours, 8 pN+ and 1 with positive margins. The mean hospital stay was 9 days. With a median follow-up of 16 months, 9 (13%) patients were readmitted after the discharge, most for infections associated with the vesical catheter and other catheters. Forty patients (59.7%) presented complications (most were Clavien grade 1-2). There was recurrence during the follow-up in 4 cases (6%), and 4 (5.9%) patients died from cancer. Nineteen (28.3%) patients had complications after 30 days, most of which were urinary tract infections. Of the 47 patients with a neobladder, 45 (96%) had proper daytime continence and 42 (89%) had proper nighttime continence. Ninety percent and 64% of the patients with previously normal sexual function and reduced sexual function, respectively, were able to preserve sexual function with or without drug treatment. Robot-assisted radical cystectomy plus lymphadenectomy, with extracorporeal reconstruction of the urinary diversion, offers good oncological and functional results without increasing the number of complications.

Autorino, Riccardo; Zargar, Homayoun; Kaouk, Jihad H

2014-10-01

The aim of the present review is to summarize recent developments in the field of urologic robotic surgery. A nonsystematic literature review was performed to retrieve publications related to robotic surgery in urology and evidence-based critical analysis was conducted by focusing on the literature of the past 5 years. The use of the da Vinci Surgical System, a robotic surgical system, has been implemented for the entire spectrum of extirpative and reconstructive laparoscopic kidney procedures. The robotic approach can be applied for a range of adrenal indications as well as for ureteral diseases, including benign and malignant conditions affecting the proximal, mid, and distal ureter. Current evidence suggests that robotic prostatectomy is associated with less blood loss compared with the open surgery. Besides prostate cancer, robotics has been used for simple prostatectomy in patients with symptomatic benign prostatic hyperplasia. Recent studies suggest that minimally invasive radical cystectomy provides encouraging oncologic outcomes mirroring those reported for open surgery. In recent years, the evolution of robotic surgery has enabled urologic surgeons to perform urinary diversions intracorporeally. Robotic vasectomy reversal and several other robotic andrological applications are being explored. In summary, robotic-assisted surgery is an emerging and safe technology for most urologic operations. The acceptance of robotic prostatectomy during the past decade has paved the way for urologists to explore the entire spectrum of extirpative and reconstructive urologic procedures. Cost remains a significant issue that could be solved by wider dissemination of the technology. Copyright © 2014 American Society for Reproductive Medicine. Published by Elsevier Inc.

Full Text Available There is a trend for the increased adoption of minimally invasive techniques of radical prostatectomy (RP – laparoscopic (LRP and robotic assisted (RARP – from the traditional open radical retropubic prostatectomy (ORP, popularised by Partin et al. Recently there has been a dramatic expansion in the rates of RARP being performed, and there have been many early reports postulating that the learning curve for RARP is shorter than for LRP. The aim of this study was to review the literature and analyse the length of the LRP learning curves for the various outcome measures: perioperative, oncologic, and functional outcomes. A broad search of the literature was performed in November 2013 using the PubMed database. Only studies of real patients and those from 2004 until 2013 were included; those on simulators were excluded. In total, 239 studies were identified after which 13 were included. The learning curve is a heterogeneous entity, depending entirely on the criteria used to define it. There is evidence of multiple learning curves; however the length of these is dependent on the definitions used by the authors. Few studies use the more rigorous definition of plateauing of the curve. Perioperative learning curve takes approximately 150-200 cases to plateau, oncologic curve approximately 200 cases, and the functional learning curve up to 700 cases to plateau (700 for potency, 200 cases for continence. In this review, we have analysed the literature with respect to the learning curve for LRP. It is clear that the learning curve is long. This necessitates centralising LRP to high volume centres such that surgeons, trainees, and patients are able to utilise the benefits of LRP.

with antibiotics and laparoscopic lavage. Conversion to laparotomy was made in six (3%) patients and the mean hospital stay was nine days. Ten percent of the patients had complications. During the mean follow-up of 38 months, 38% of the patients underwent elective sigmoid resection with primary anastomosis....... CONCLUSION: Primary laparoscopic lavage for complicated diverticulitis may be a promising alternative to more radical surgery in selected patients. Larger studies have to be made before clinical recommendations can be given....

At present, Da Vinci robotic assisted hepatectomy has been routinely carried out in conditional units. But there is no report concerning the use of Da Vinci robots for hepatic hydatid cystectomy and experience on this aspect is seldom mentioned before. This study was to summarize the preliminary experience in laparoscopic resection of hepatic hydatidectocyst with the Da Vinci Surgical System (DVSS). A 29-year-old female diagnosed as hepatic hydatid in the right anterior lobe of liver was treated with laparoscopic resection by the DVSS under general anesthesia. Appropriate disposal of tumor cell in vascular system and disinfection of surgical field with hypertonic saline were conducted. The hepatic hydatidectocyst was resected completely with an operation time of 130 min, an intraoperative blood loss of 200 ml and a length of hospital stay for five days. The vital signs of patient were stable and no cyst fluid allergy occurred after operation. Our result showed that laparoscopic resection of hepatic hydatidectocyst by using the DVSS is safe and feasible on the basis of hospitals have rich experience in treatment of cystic echinococcosisliver, resection with DVSS and laparoscopic excision.

Functional outcomes after ileal bladder substitution reflect the expectations of future patients at a particular centre. The aim of this study was to use validated questionnaires and a pad-weighing test to investigate functional outcomes after neobladder reconstruction at long-term follow-up in patients at a single centre. During 2005 - 2015, 75 patients received a Studer ileal bladder substitute at the Department of Urology, Malmö. Forty-six of these patients were alive for follow-up and were evaluated using the pad-weighing test and the International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form (ICIQ-UI-SF), the Female Sexual Function Index (FSFI) and the International Index of Erectile Function (IIEF). Five of 37 evaluable patients (14%) were considered fully continent, reporting a pad-weighing test result of 0 g and an ICIQ-UI-SF score of 0. The median ICIQ-UI-SF score was 8 [interquartile range (IQR) 3-11], and seven patients (17%) were continent according to the ICIQ-UI-SF score only. In the pad-weighing test, 28 out of 37 patients (76%) reported 0 g day-time leakage whereas only 12 out of 37 patients (32%) reported 0 g night-time leakage. At follow-up, nine out of 39 (23%) of evaluable male patients were potent. The median ICIQ-UI-SF score was significantly lower during the second half of the study period [4 (IQR 0-8) vs 10 (IQR 6-14); p = .003]. The inverse applied to the median IIEF score [5 (IQR 3-12) vs 2 (IQR 1-4); p = .02]. Functional outcomes at long-term follow-up after radical cystectomy and Studer ileal bladder substitute were at best modest in this series. Better outcomes during the second half of the study period might be explained by improved patient selection and a refined surgical technique, but possibly also by longer follow-up of patients during the first half of the period resulting in a more pronounced time-dependent decline in functional outcomes.

To evaluate the differences in estimated glomerular filtration rate decline by urinary diversion type (incontinent diversion vs continent diversion) and preoperative estimated glomerular filtration rate among patients undergoing radical cystectomy and urinary diversion. We evaluated 1383 patients treated with radical cystectomy between 1980-2006 who had a preoperative estimated glomerular filtration rate of 45-89 mL/min/1.73 m(2). Estimated glomerular filtration rate was estimated using Chronic Kidney Disease Epidemiology Collaboration equations, and patients were stratified by preoperative estimated glomerular filtration rate into chronic kidney disease 2 (estimated glomerular filtration rate 60-89 mL/min/1.73 m(2)) and chronic kidney disease 3a (estimated glomerular filtration rate 45-59 mL/min/1.73 m(2)). Multiple definitions of estimated glomerular filtration rate decline were evaluated: (i) 10-point decline in estimated glomerular filtration rate; (ii) 20% decline in estimated glomerular filtration rate; and (iii) 10% decline in estimated glomerular filtration rate. Time to estimated glomerular filtration rate decline was compared using the Kaplan-Meier method stratified by diversion type. Cox regression models were used to evaluate the association of diversion type with estimated glomerular filtration rate decline risk. In total, 74% (1021/1383) of patients underwent incontinent diversion and 26% (362/1383) underwent continent diversion. Preoperative chronic kidney disease 2 and chronic kidney disease 3a were noted among 59% and 41% of patients who underwent incontinent diversion, versus 74% and 26% with continent diversion. Median follow up after RC was 11.2 years. The rate of estimated glomerular filtration rate decline in patients with incontinent diversion versus continent diversion was similar when stratified by preoperative chronic kidney disease 2 and preoperative chronic kidney disease 3a, regardless of estimated glomerular

The role of adjuvant chemotherapy (AC) within urothelial carcinoma of the urinary bladder (UCUB) patients after radical cystectomy (RC) is under debate. We assessed contemporary AC utilization rates. We also examined the rates of AC according to patient disease and sociodemographic characteristics. We relied on the SEER-Medicare database for non-organ-confined, muscle-invasive T2 N+ -T4a UCUB patients who underwent RC between 1991 and 2009 without neoadjuvant chemotherapy delivery. Multivariable logistic regression analyses tested predictors of AC use; T-stage, N-stage, year of diagnosis, age, gender, race, radiotherapy (RT) administration, marital urban and socioeconomic status, tumor grade and Charlson Comorbidity Index (CCI). Overall, 2681 patients were identified. Of those, 667 (24.9%) received AC. The rate of AC were 21.4%, 23.5%, 24.6% and 29.9% over time (1991-1999 vs. 2000-2002 vs. 2003-2005 vs. 2006-2009) (P=0.002). In multivariable analyses stages pT2N+ (odds ratio (OR): 4.7; Pmarried status (OR: 1.4; P=0.001) and advanced age (OR: 0.3; Punmarried individuals were less likely to receive AC. AC rates were higher in T2N+ UCUB patients than in T3-T4a individuals.

2011-01-01

Conclusions: Cancer-specific survival is statistically comparable for primary and deferred cystectomy in T1 bladder cancer, although there is a non-significant difference in favor of primary cystectomy. In the deferred cystectomy group, the number of TURBTs beyond three is associated with lower survival. Conservative treatment should be adopted for most cases in this category.

Purpose: To examine the accuracy of clinical staging and its effects on outcome in bladder cancer (BC) patients treated with radical cystectomy (RC), using a large national database. Methods and Materials: A total of 16,953 patients with BC without distant metastases treated with RC from 1998 to 2009 were analyzed. Factors associated with clinical–pathologic stage discrepancy were assessed by multivariate generalized estimating equation models. Survival analysis was conducted for patients treated between 1998 and 2004 (n=7270) using the Kaplan-Meier method and Cox proportional hazards models. Results: At RC 41.9% of patients were upstaged, whereas 5.9% were downstaged. Upstaging was more common in females, the elderly, and in patients who underwent a more extensive lymphadenectomy. Downstaging was less common in patients treated at community centers, in the elderly, and in Hispanics. Receipt of preoperative chemotherapy was highly associated with downstaging. Five-year overall survival rates for patients with clinical stages 0, I, II, III, and IV were 67.2%, 62.9%, 50.4%, 36.9%, and 27.2%, respectively, whereas those for the same pathologic stages were 70.8%, 75.8%, 63.7%, 41.5%, and 24.7%, respectively. On multivariate analysis, upstaging was associated with increased 5-year mortality (hazard ratio [HR] 1.80, P<.001), but downstaging was not associated with survival (HR 0.88, P=.160). In contrast, more extensive lymphadenectomy was associated with decreased 5-year mortality (HR 0.76 for ≥10 lymph nodes examined, P<.001), as was treatment at an National Cancer Institute–designated cancer center (HR 0.90, P=.042). Conclusions: Clinical–pathologic stage discrepancy in BC patients is remarkably common across the United States. These findings should be considered when selecting patients for preoperative or nonoperative management strategies and when comparing the outcomes of bladder sparing approaches to RC.

Full Text Available Abstract Background Although surgery and anesthesia induce immunesuppression, remains largely unknown whether various anesthetic techniques have different immunosuppressive effects on cancer patients. Therefore, the aim of this study was to investigate the influence of total intravenous anesthesia with target-controlled infusion (TIVA-TCI and balanced inhalation anesthesia (BAL on the peri-operative levels of inflammatory cytokines and regulatory T cells (Tregs in patients with bladder cancer undergoing surgery. Methods Twenty eight consecutive patients with bladder cancer who underwent radical cystectomy were prospectively randomized into two groups to receive TIVA-TCI (n = 14 or BAL (n = 14. Before the induction of anesthesia (T0, 6–8 hours (T1 post-surgery, and 5 days post-surgery (T2, Tregs and serum levels of interleukin -1beta (IL-1β, interferon-gamma (IFN-γ, tumor necrosis factor-alpha (TNF-α, interleukin −2 (IL-2, interleukin −6 (IL-6, and interleukin −10 (IL-10 were measured. Results In the peri-operative period all cancer patients showed a marked and significant increase in IL-6. Moreover, TIVA-TCI patients also showed a higher increase in IFN-γ, whereas in BAL patients Tregs were reduced by approximately 30% during surgery. The incidence of infections, metastases, and death was similar in both groups. Conclusions The increase in the Th1 response in the TIVA-TCI group and the reduction in Tregs in the BAL group seem to balance the immunosuppressive effect induced by IL-6. Therefore TIVA-TCI and BAL can be both used in major surgery in patients with bladder cancer without worsening the outcome.

We investigated trends in perioperative chemotherapy use, and determined factors associated with neoadjuvant chemotherapy (NAC) and adjuvant chemotherapy (AC) use in Korean patients with muscle-invasive bladder cancer (MIBC). We recruited 1,324 patients who had MIBC without nodal invasion or metastases and had undergone radical cystectomies (RC) between 2003 and 2013. The study's cut-off time for AC was three months after surgery, and the study's timespan was divided into three periods based on NAC use, namely, 2003-2005, 2006-2009, and 2010-2013. Complete remission was defined as histologically confirmed T0N0M0 after RC. NAC and AC were administered to 7.3% and 18.1% of the patients, respectively. The median time interval between completing NAC and undergoing RC was 32 days and the mean number of cycles was 3.2. The median time interval between RC and AC was 43 days and the mean number of cycles was 4.1. Gemcitabine and cisplatin were most frequently used in combination for NAC (49.0%) and AC (74.9%). NAC use increased significantly from 4.6% between 2003 and 2005 to 8.4% between 2010 and 2013 (P < 0.05), but AC use did not increase. Only 1.9% of patients received NAC and AC. Complete remission after NAC was achieved in 12 patients (12.5%). Multivariable modeling revealed that an advanced age, the earliest time period analyzed, and clinical tumor stage ≤ cT2 bladder cancer were negatively associated with NAC use (P < 0.05). While NAC use has slowly increased over time, it remains an underutilized therapeutic approach in Korean clinical practice. PMID:26240494

Due to the emphasis of oncologic principle, a medial-to-lateral approach for laparoscopic right hemicolectomy was recommended.1 (,) 2 This approach, however, is technically challenging and involves several limitations with overweight patients, whose mesocolon may be too thick for identification of the vessel landmarks. Moreover, it is difficult for inexperienced surgeons to enter the retroperitoneum space accurately. This report describes a caudal-to-cranial approach for laparoscopic radical extended right hemicolectomy. First, a "yellow-white borderline" between the right mesostenium and retroperitoneum in the right iliac fossa is dissected as the entry for separation of the fusion fascial space between the visceral and parietal peritoneum.3 The right Toldt's fascia is dissected and expanded medial to the periphery of the superior mesenteric vein (SMV), cranial to the pancreas head, and lateral to the ascending colon. The posterior paries of ileocolic vessels (ICVs), right colic vessels (RCVs), and Henle's trunk are exposed. Second, the mesocolon between the ICV and SMV is dissected safely, and the ICV, RCV, and right gastroepiploic vessels as well as the right branch of the middle colic vessel are divided and ligated easily because of the separated retroperitoneal space. The lymph nodes along the SMV are dissected using a caudal-to-cranial approach. Third, the greater omental is dissected for full mobilization of the mesocolon containing 10 cm of normal colon distal to the lesion followed by complete mobilization of the lateral attachments of the ascending colon. In this study, 10 men and 8 women with hepatic flexure cancer underwent laparoscopic extended right hemicolectomy using a caudal-to-cranial approach. No conversion was recorded. The overall complication rate was 11.2 %, including one case of pulmonary infection and one case of urinary tract infection, both of which were cured with conservative measures. The mean age of the patients was 61.3 ± 12.7�

The T1 renal cancer in adults is made known; incidence, characteristics and management. Renal cell carcinoma has been the most common malignancy of the kidney, percentage is close to three percent of solid tumors of adults. The treatments for this tumor are analyzed: open radical nephrectomy, laparoscopic radical nephrectomy, open partial nephrectomy and laparoscopic partial nephrectomy. Laparoscopic partial nephrectomy has represented an alternative option acceptable, safely and with good oncological and surgical outcomes for patients, as it is used to conserve nephrons and simultaneously to resect the tumor of a complete form promoting in the future the patient present a good renal function. Additionally, a adequate oncological control has reduced the risk of submit postoperative renal failure. An evolution of laparoscopic partial nephrectomy is presented determining the procedure for renal tumors in state T1 in the adults [es

The incidence, treatment, and outcome of urethral recurrence (UR) after radical cystectomy (RC) for muscle-invasive bladder cancer with orthotopic neobladder in women have rarely been addressed in the literature. A total of 12 patients (median age at recurrence: 60 years) who experienced UR after RC with an orthotopic neobladder were selected for this study from a cohort of 456 women from participating institutions. The primary clinical and pathological characteristics at RC, including the manifestation of the UR and its treatment and outcome, were reviewed. The primary bladder tumors in the 12 patients were urothelial carcinoma in 8 patients, squamous cell carcinoma and adenocarcinoma in 1 patient each, and mixed histology in 2 patients. Three patients (25%) had lymph node-positive disease at RC. The median time from RC to the detection of UR was 8 months (range 4-55). Eight recurrences manifested with clinical symptoms and 4 were detected during follow-up or during a diagnostic work-up for clinical symptoms caused by distant metastases. Treatment modalities were surgery, chemotherapy, radiotherapy, and bacillus Calmette-Guérin urethral instillations. Nine patients died of cancer. The median survival after the diagnosis of UR was 6 months. UR after RC with an orthotopic neobladder in females is rare. Solitary, noninvasive recurrences have a favorable prognosis when detected early. Invasive recurrences are often associated with local and distant metastases and have a poor prognosis. © 2014 S.

Purpose: Local-regional failures (LF) following radical cystectomy (RC) plus pelvic lymph node dissection (PLND) with or without chemotherapy for invasive urothelial bladder carcinoma are more common than previously reported. Adjuvant radiation therapy (RT) could reduce LF but currently has no defined role because of previously reported morbidity. Modern techniques with improved normal tissue sparing have rekindled interest in RT. We assessed the risk of LF and determined those factors that predict recurrence to facilitate patient selection for future adjuvant RT trials. Methods and Materials: From 1990-2008, 442 patients with urothelial bladder carcinoma at University of Pennsylvania were prospectively followed after RC plus PLND with or without chemotherapy with routine pelvic computed tomography (CT) or magnetic resonance imaging (MRI). One hundred thirty (29%) patients received chemotherapy. LF was any pelvic failure detected before or within 3 months of distant failure. Competing risk analyses identified factors predicting increased LF risk. Results: On univariate analysis, pathologic stage {>=}pT3, <10 nodes removed, positive margins, positive nodes, hydronephrosis, lymphovascular invasion, and mixed histology significantly predicted LF; node density was marginally predictive, but use of chemotherapy, number of positive nodes, type of surgical diversion, age, gender, race, smoking history, and body mass index were not. On multivariate analysis, only stage {>=}pT3 and <10 nodes removed were significant independent LF predictors with hazard ratios of 3.17 and 2.37, respectively (P<.01). Analysis identified 3 patient subgroups with significantly different LF risks: low-risk ({<=}pT2), intermediate-risk ({>=}pT3 and {>=}10 nodes removed), and high-risk ({>=}pT3 and <10 nodes) with 5-year LF rates of 8%, 23%, and 42%, respectively (P<.01). Conclusions: This series using routine CT and MRI surveillance to detect LF confirms that such failures are relatively common

To help determine whether global collaborations for prospective gynecologic surgery trials should include hospitals in developing countries, we compared surgical and oncologic outcomes of patients undergoing laparoscopic radical hysterectomy at a large comprehensive cancer center in the United States and a cancer center in Colombia. Records of the first 50 consecutive patients who underwent laparoscopic radical hysterectomy at The University of Texas MD Anderson Cancer Center in Houston (between April 2004 and July 2007) and the first 50 consecutive patients who underwent the same procedure at the Instituto de Cancerología-Clínica las Américas in Medellín (between December 2008 and October 2010) were retrospectively reviewed. Surgical and oncologic outcomes were compared between the 2 groups. There was no significant difference in median patient age (US 41.9 years [range 23-73] vs. Colombia 44.5 years [range 24-75], P=0.09). Patients in Colombia had a lower median body mass index than patients in the US (24.4 kg/m(2) vs. 28.7 kg/m(2), P=0.002). Compared to patients treated in Colombia, patients who underwent surgery in the US had a greater median estimated blood loss (200 mL vs. 79 mL, P<0.001), longer median operative time (328.5 min vs. 235 min, P<0.001), and longer postoperative hospital stay (2 days vs. 1 day, P<0.001). Surgical and oncologic outcomes of laparoscopic radical hysterectomy were not worse at a cancer center in a developing country than at a large comprehensive cancer center in the United States. These results support consideration of developing countries for inclusion in collaborations for prospective surgical studies. Copyright © 2011 Elsevier B.V. All rights reserved.

Laparoscopic managment of common bile duct stones: our initial experience.

The management of choledocholithiasis has changed radically since the introduction of laparoscopic cholecystectomy. However, perceived technical difficulties have deterred many surgeons from treating common bile duct stones laparoscopically at the time of cholecystectomy. This has lead to reliance on endoscopic retrograde cholangiopancreatography followed by endoscopic sphincterotomy to deal with common bile duct stones. We retrospectively reviewed the charts of patients who had laparoscopic common bile duct exploration at Downe Hospital between December 1999 and August 2001. Among 149 laparoscopic cholecystectomies done by our group in this period, 10 patients (6.7%) underwent laparoscopic CBD exploration, three by the transcystic technique and seven by choledochotomy. Three patients (2%) had unsuspected stones found on routine per- operative cholangiogram. The mean operative time was 2.34hrs (range 1.50-3.30hrs). The mean hospital post- operative stay was 3 days (range 1-6 days). Post-operative morbidity was zero. Stone clearance was achieved in all cases. We conclude, laparoscopic exploration of the common bile duct is relatively safe and straightforward method. The key skill required is the ability to perform laparoscopic suturing with confidence.

Full Text Available Aims: Primary cysts and tumors of the ovary alongwith torsion are often regarded as an indication for open oophorectomy because of the fear of leaving an ischemic organ inside and chances of recurrence. We wish to report our experience of both modalities of management where we initially removed adenexal torsion by either laparoscopic salpingo-oophorectomy or oophorectomy, but later followed a more conservative approach of adenexal lesion removal with ovarian preservation. Materials and Methods: Retrospective review of clinical records of patients with ovarian pathology who were managed laparoscopically. Results: 46 cases of pediatric ovarian pathology were managed between March 2006 and March 2013 in two centers by a team of surgeons. The age ranged from 1 days to 18 years (average 14.3 years and the pathology varied from 30 cases of a simple ovarian cyst with torsion, 3 cases of ovarian torsion without any cyst, 7 cases of a dermoid cyst with torsion in all, 1 case of secreting ovarian tumor and 5 cases of a paraovarian cyst with torsion. All patients had a normal tumor marker except 1 girl with a functional ovarian tumor who had elevated LDH and estrogen levels alongwith suppressed LH and FSH. In the initial period of our study we did 1 salpingo-oophorectomy for a suspected complex lesion and two oophorectomies for torsion with a simple cyst. In the later part of our study we performed laparoscopic cystectomy and ovarian preservation in 40 cases, including 7 cases of dermoid, where we performed laparoscopic detorsion with dermoid cystectomy and ovarian preservation in the same sitting. In three cases of chronic torsion who presented to us late, we could not preserve the ovary and had to resort to salpingo-ophorectomy. Histology showed a simple corpus luteal and follicular ovarian cyst in 31 cases, a paraovarian cyst in 5 cases with mature teratoma in 7 cases. Twenty-five patients with ovarian preservation following detorsion were subjected to

A case report. Instituto de Fertilidad y Ginecología de Buenos Aires (IFER), Buenos Aires, Argentina. Infertile patient undergoing surgery due to an endometriotic cyst of the left ovary. Laparoscopic cystectomy. Accidental retention of a portion of the capsule and adjacent ovarian tissue of the endometrioma in SC cellular tissue. Months after surgery, a SC tumor was formed under the surgical incision. It was subsequently excised. Observation of tumor growth during menstrual cycles and ovulation induction; anatomopathologic study of the tissue after its extirpation. The tumor grew spontaneously in the periovulatory period and during treatments of ovulation induction. The anatomopathologic report of the tumor, removed 15 months after the first surgery, revealed functioning ovarian tissue with vessels of neoformation. This is the first description of autografted ovarian tissue in humans. We describe that the ovary can maintain its ovulatory function even in the absence of its pedicel. Also, we suggest that extirpation of surgical material through the incision of the trocar is not recommended, as the possibility of "sowing" or of autografts may occur.

In the past decade, adjuvant chemotherapy (AC) after radical cystectomy (RC) was preferred worldwide for patients with muscle-invasive urothelial bladder cancer. In this study we aimed to determine the outcome of patients who received AC and evaluated prognostic factors associated with survival. We retrospectively analyzed 226 consecutive patients treated in 6 academic hospitals between 2000 and 2009. Multivariate Cox proportional hazards regression adjusted for center to estimate adjusted hazard ratios (HRs) with 95% confidence intervals were used. The median age was 62.4 (range, 35-82) years. Patients had pT3/pT4 and/or pN+ in 180 (79.6%) and 168 patients (74.3%), respectively. Median lymph node (LN) density was 25% (range, 3.1-100). Median time between RC and AC was 61.5 (range, 18-162) days. Gemcitabine with cisplatin, gemcitabine with carboplatin, and MVAC (methotrexate, vinblastine, doxorubicin, and cisplatin) regimens were delivered in 161 (71.2%), 49 (21.7%), and 12 patients (5.3%) of patients, respectively. The median number of cycles was 4 (range, 1-6). Thirteen patients (5.7%) with LN metastases also received adjuvant pelvic radiotherapy (ART). After a median follow-up of 4.2 years, 5-year overall survival (OS) was 40.7%. In multivariate analysis, pT ≥3 stage (HR, 1.73; P = .05), LN density >50% (HR, 1.94; P = .03), and number of AC cycles Classical prognostic features associated with survival are not modified by the use of AC. Patients who derived benefit from AC had a low LN density and received at least 4 cycles of treatment. Copyright © 2016 Elsevier Inc. All rights reserved.

Mature cystic teratomas, often referred to as dermoid cysts, are the most common germ cell tumors of the ovary in the recent years, transvaginal sonographic diagnosis of ovarian dermoid cysts together with the laparascopic approach have greatly improved the treatment of this benign lesion. We retrospectively reviewed the outcome of laparoscopic surgery for suspected ovarian dermoid cysts. The preoperative findings, operative techniques, and postoperative complications were retrospectively reviewed in the women who underwent lpaparoscopic surgey for dermoid cysts, between January 2001 and May 2003. In 47 women aged 21 to 53 years (median, 38.8 years), 93.6% had a unilateral cyst with a diameter of 17 to 108 mm (median 51 mm). Clinical presentations were pain (62%), abnormal vaginal bleeding (21%) and ovarian torsion (2%), while 17%were diagnosed incidently during routine examination. Surgery included cystectomy (57%), total (36%) or partial oophorectomy (6.4%) and laparoscopic assisted vaginal hysterectomy with bilateral salpingo-oophorectomy (2%). During the cyst extraction, minimal spillage occured in 42.5% of the casesand none developed chemical peritonitis. In 2 patients, conversion to laparotomy (4.3%) was required, one for sigmoid colon, injury and one for malignent ovarian tumor detected via frozen section. The median operating time was 80 minutes (range, 35-180 minutes). Using strict afherence to guidelines for preoperative clinical assessment and intraoperative management, laparoscopic treatment of dermoid cysts appers to be a safe procedure. (author)

Robot-assisted laparoscopic radical prostatectomy with early retrograde release of the neurovascular bundle and endopelvic fascia sparing

Directory of Open Access Journals (Sweden)

George Augusto Monteiro Lins de Albuquerque

Full Text Available ABSTRACT Introduction Robotic-assisted radical prostatectomy (RAP is the dominant minimally invasive surgical treatment for patients with localized prostate cancer. The introduction of robotic assistance has the potential to improve surgical outcomes and reduce the steep learning curve associated with conventional laparoscopic radical prostatectomy. The purpose of this video is to demonstrate the early retrograde release of the neurovascular bundle without open the endopelvic fascia during RAP. Materials and Methods A 51-year old male, presenting histological diagnosis of prostate adenocarcinoma, Gleason 6 (3+3, in 4 cores of 12, with an initial PSA=3.41ng/dl and the digital rectal examination demonstrating a prostate with hardened nodule in the right lobe of the prostate base (clinical stage T2a. Surgical treatment with the robot-assisted technique was offered as initial therapeutic option and the critical technical point was the early retrograde release of the neurovascular bundle with endopelvic fascia preservation, during radical prostatectomy. Results The operative time was of 89 minutes, blood loss was 100ml. No drain was left in the peritoneal cavity. The patient was discharged within 24 hours. There were no intraoperative or immediate postoperative complications. The pathological evaluation revealed prostate adenocarcinoma, Gleason 6, with free surgical margins and seminal vesicles free of neoplastic involvement (pathologic stage T2a. At 3-month-follow-up, the patient lies with undetectable PSA, continent and potent. Conclusion This is a feasible technique combining the benefits of retrograde release of the neurovascular bundle, the preservation of the pubo-prostatic collar and the preservation of the antero-lateral cavernous nerves.

Urologic robotic surgery in Korea: past and present.

2015-08-01

Since 2005 when the da Vinci surgical system was approved as a medical device by the Korean Ministry of Health and Welfare, 51 systems have been installed in 40 institutions as of May 2015. Although robotic surgery is not covered by the national health insurance service in Korea, it has been used in several urologic fields as a less invasive surgery. Since the first robotic-assisted laparoscopic radical prostatectomy in 2005, partial nephrectomy, radical cystectomy, pyeloplasty, and other urologic surgeries have been performed. The following should be considered to extend the indications for robotic surgery: training systems including accreditation, operative outcomes from follow-up results, and cost-effectiveness. In this review, the history and current status of robotic surgeries in Korea are presented.

The type of surgery or surgical approach for transverse colon cancer treatment largely depends on the tumor location or surgeon's preference. However, extensive lymphadenectomy appears to improve the long-term outcomes of locally advanced colon cancers. This study was designed to compare the short- and long-term outcomes after surgery via the laparoscopic or open approach with radical D3 lymph node dissection in patients with stage II and III transverse colon cancer. Patients were treated for stage II and III transverse colon cancer between May 2006 and December 2014. This retrospective study evaluated data collected prospectively at a tertiary teaching hospital. Radical D3 lymphadenectomy included the principal middle colic artery nodes. The study included 144 patients among whom 118 (81.9%) underwent laparoscopic surgery. Significantly more patients in the laparoscopic group underwent extended right hemicolectomy compared with the open group (90.7 vs. 65.4%, p = 0.005). The operative time was longer in the laparoscopic group (151.3 vs. 131.2 min, p = 0.021), and the open group had a greater estimated blood loss volume (160.8 vs. 289.3 ml, p = 0.011). Although the groups differed in terms of tumor size (5.8 vs 7.9 cm, p = 0.007), other pathologic outcomes did not differ. The groups did not differ regarding postoperative parameters or disease-free, overall, and cancer-specific survivals. Despite differences in surgical methods and related factors, no long-term differences in outcomes were observed between laparoscopic and open approaches to radical D3 lymphadenectomy in patients with stage II and III transverse colon cancer.

In the present study, we review current literature and based on our experience, we present the anatomical landmarks of open and laparoscopic/endoscopic radical prostatectomy. A thorough literature search was performed with the Medline database on the anatomy and the nomenclature of the structures surrounding the prostate gland. The correct handling of puboprostatic ligaments, external urethral sphincter, prostatic fascias and neurovascular bundle is necessary for avoiding malfunction of the urogenital system after radical prostatectomy. When evaluating new prostatectomy techniques, we should always take into account both clinical and final oncological outcomes. The present review adds further knowledge to the existing "postprostatectomy anatomical hazard" debate. It emphasizes upon the role of the puboprostatic ligaments and the course of the external urethral sphincter for urinary continence. When performing an intrafascial nerve sparing prostatectomy most urologists tend to approach as close to the prostatic capsula as possible, even though there is no concurrence regarding the nomenclature of the surrounding fascias and the course of the actual neurovascular bundles. After completion of an intrafascial technique the specimen does not contain any periprostatic tissue and thus the detection of pT3a disease is not feasible. This especially becomes problematic if the tumour reaches the resection margin. Nerve sparing open and laparoscopic radical prostatectomy should aim in maintaining sexual function, recuperating early continence after surgery, without hindering the final oncological outcome to the procedure. Despite the different approaches for radical prostatectomy the key for better results is the understanding of the anatomy of the bladder neck and the urethra.

The current study was performed to examine temporal trends and compare overall survival (OS) in patients undergoing radical cystectomy (RC) or bladder-preservation therapy (BPT) for muscle-invasive urothelial carcinoma of the bladder. The authors reviewed the National Cancer Data Base to identify patients with AJCC stage II to III urothelial carcinoma of the bladder from 2004 through 2013. Patients receiving BPT were stratified as having received any external-beam radiotherapy (any XRT), definitive XRT (50-80 grays), and definitive XRT with chemotherapy (CRT). Treatment trends and OS outcomes for the BPT and RC cohorts were evaluated using Cochran-Armitage tests, unadjusted Kaplan-Meier curves, adjusted Cox multivariate regression, and propensity score matching, using increasingly stringent selection criteria. A total of 32,300 patients met the inclusion criteria and were treated with RC (22,680 patients) or BPT (9620 patients). Of the patients treated with BPT, 26.4% (2540 patients) and 15.5% (1489 patients), respectively, were treated with definitive XRT and CRT. Improved OS was observed for RC in all groups. After adjustments with more rigorous statistical models controlling for confounders and with more restrictive BPT cohorts, the magnitude of the OS benefit became attenuated on multivariate (any XRT: hazard ratio [HR], 2.115 [95% confidence interval [95% CI], 2.045-2.188]; definitive XRT: HR, 1.870 [95% CI, 1.773-1.972]; and CRT: HR, 1.578 [95% CI, 1.474-1.691]) and propensity score (any XRT: HR, 2.008 [95% CI, 1.871-2.154]; definitive XRT: HR, 1.606 [95% CI, 1.453-1.776]; and CRT: HR, 1.406 [95% CI, 1.235-1.601]) analyses. In the National Cancer Data Base, receipt of BPT was associated with decreased OS compared with RC in patients with stage II to III urothelial carcinoma. Increasingly stringent definitions of BPT and more rigorous statistical methods adjusting for selection biases attenuated observed survival differences. Cancer 2017;123:4337-45. © 2017

Previous studies done in animals have shown that significant prophylaxis against radiation injury could be afforded by feeding an elemental diet (ED) for three days before and during radiation. In the present study 20 patients were fed an ED for three days before and for the four days during radiotherapy (five fractions of 400 rad [4 Gy] each) prior to radical cystectomy and ileal conduit for invasive bladder cancer; ED feeding was recommenced 24 hours postoperatively via a feeding jejunostomy. The ED-fed patients exhibited positive nitrogen balance preoperatively and had an early return to positive nitrogen balance postoperatively (3.60 +/- 0.32 days). There was also prompt return of bowel sounds (3.00 +/- 0.32 days). Histologically and ultrastructurally, biopsy specimens of the ileal mucosa showed normal morphologic findings, with maintenance of normal levels of enzyme activity in the brush border. Severe or bloody diarrhea was absent in these patients. These data suggest that ED feeding provides prophylaxis against the acute phase of radiation injury in patients undergoing high-dose, short-course radiotherapy for invasive bladder cancer and that it is a safe and feasible means of postoperative nutritional support, even in the presence of a fresh bowel anastomosis

Full Text Available Robot-assisted laparoscopic prostatectomy (RALP has emerged as the most common treatment for localized prostate cancer. With improved surgical precision, RALP has produced hope of improved potency rates, especially with the advent of nerve-sparing and other modified techniques. However, erectile dysfunction (ED remains a significant problem for many men regardless of surgical technique. To identify the functional outcomes of robotic versus open and laparoscopic techniques, new robotic surgical techniques and current treatment options of ED following RALP. A Medline search was performed in March 2014 to identify studies comparing RALP with open retropubic radical prostatectomy (RRP and laparoscopic radical prostatectomy, modified RALP techniques and treatment options and management for ED following radical prostatectomy. RALP demonstrates adequate potency rates without compromising oncologic benefit, with observed benefit for potency rates compared with RRP. Additionally, specific surgical technical modifications appear to provide benefit over traditional RALP. Phosphodiesterase-5 inhibitors (PDE5I demonstrate benefit for ED treatment compared with placebo. However, long-term benefit is often lost after use. Other therapies have been less extensively studied. Additionally, correct patient identification is important for greatest clinical benefit. RALP appears to provide beneficial potency rates compared with RRP; however, these effects are most pronounced at high-volume centers with experienced surgeons. No optimal rehabilitation program with PDE5Is has been identified based on current data. Additionally, vacuum erection devices, intracavernosal injections and other techniques have not been well validated for post RALP ED treatment.

To evaluate the association of ABO blood type with clinicopathologic outcomes and mortality among patients with urothelial carcinoma of the bladder treated with radical cystectomy (RC). We identified 2,086 consecutive patients who underwent RC between 1980 and 2008. Postoperative recurrence-free survival (RFS) and cancer-specific survival (CSS) were estimated using the Kaplan Meier method and compared with the log-rank test. Cox proportional hazards regression models were used to evaluate the association of ABO blood type with outcomes. A total of 913 (44%), 881 (42%), 216 (10%), and 76 (4%) patients had blood type O, A, B, and AB, respectively. Median postoperative follow-up among survivors was 11.0 years (interquartile range: 7.7-15.9y). Overall, 1,561 patients died, with 770 deaths attributable to bladder cancer. Non-O blood type was associated with significantly worse 5-year RFS (65% vs. 69%; P = 0.04) and/or CSS (64% vs. 70%; P = 0.02). In particular, among patients with≤pT2N0 disease, the 5-year RFS for those with non-O vs. O blood type was 75% vs. 82%, respectively (P = 0.002), whereas the 5-year CSS was 77% vs. 85%, respectively (P = 0.001). Moreover, on multivariable analysis, blood type A remained independently associated with an increased risk of cancer-specific mortality (hazard ratio = 1.22; P = 0.01). Non-O blood type, particularly blood type A, is associated with a significantly increased risk of death from bladder cancer among patients undergoing RC. If validated, the utility of a multimodal therapy approach, including perioperative chemotherapy, or more frequent postoperative surveillance in this cohort warrants further study.

To describe surgical and functional results with extraperitoneal laparoscopic radical prostatectomy with duplication of the open technique, from the experience obtained in the treatment of 28 initial cases. In a 36-month period, we prospectively analyzed 28 patients diagnosed with localized prostate cancer undergoing extraperitoneal laparoscopic radical prostatectomy. Mean surgical time was 280 min, with mean blood loss of 320 mL. As intraoperative complications, there were 2 rectal lesions repaired with laparoscopic suture in 2 planes. There was no conversion to open surgery. Median hospital stay was 3 days, with return to oral diet in the first post-operative day in patients. As post-operative complications, there were 3 cases of extraperitoneal urinary fistula. Two of these cases were resolved by maintaining a Foley catheter for 21 days, and the other one by late endoscopic reintervention for repositioning the catheter. Five out of 18 previously potent patients evolved with erectile dysfunction. The diagnosis of prostate cancer was confirmed in all patients, with focal positive margin occurring in 3 cases. During a mean follow-up of 18 months, 2 patients presented increased PSA, with no clinical evidence of disease. Laparoscopic radical prostatectomy is a laborious and difficult procedure, with a long learning curve. Extraperitoneal access is feasible, and it is possible to practically duplicate the principles of open surgery. The present technique can possibly offer advantages in terms of decreased blood loss, preservation of erectile function and prevention of positive margins.

To present our single-center experience with retroperitoneal laparoscopic partial nephrectomy (LPN) and retroperitoneal laparoscopic radical nephrectomy (LRN) for T1 renal hilar tumors and evaluate which one is better. A retrospective review of 63 patients with hilar tumors undergoing retroperitoneal LPN or LRN was performed. The perioperative characteristics, change in estimated glomerular filtration rate (eGFR) from baseline to month 3, and oncologic outcomes were summarized. In total, 25 patients underwent LPN, and 38 patients underwent LRN. The mean tumor size in the LPN and LRN groups was 4.5 and 4.9 cm, respectively. The mean operation time was longer in the LPN group than that in the LRN group (212.5 minutes versus 160.7 minutes, respectively; P  .05). In experienced hands, although retroperitoneal LRN can result in shorter operation times and shorter lengths of stay, retroperitoneal LPN can preserve renal function better than LRN. Retroperitoneal LPN should be the priority in selected patients with T1 renal hilar tumors, especially for patients with renal insufficiency.

Three-dimensional (3D) imaging systems have been introduced worldwide for surgical instrumentation. A difficulty of laparoscopic surgery involves converting two-dimensional (2D) images into 3D images and depth perception rearrangement. 3D imaging may remove the need for depth perception rearrangement and therefore have clinical benefits. We conducted a multicenter, open-label, randomized trial to compare the surgical outcome of 3D-high-definition (HD) resolution and 2D-HD imaging in laparoscopic radical prostatectomy (LRP), in order to determine whether an LRP under HD resolution 3D imaging is superior to that under HD resolution 2D imaging in perioperative outcome, feasibility, and fatigue. One-hundred twenty-two patients were randomly assigned to a 2D or 3D group. The primary outcome was time to perform vesicourethral anastomosis (VUA), which is technically demanding and may include a number of technical difficulties considered in laparoscopic surgeries. VUA time was not significantly shorter in the 3D group (26.7 min, mean) compared with the 2D group (30.1 min, mean) (p = 0.11, Student's t test). However, experienced surgeons and 3D-HD imaging were independent predictors for shorter VUA times (p = 0.000, p = 0.014, multivariate logistic regression analysis). Total pneumoperitoneum time was not different. No conversion case from 3D to 2D or LRP to open RP was observed. Fatigue was evaluated by a simulation sickness questionnaire and critical flicker frequency. Results were not different between the two groups. Subjective feasibility and satisfaction scores were significantly higher in the 3D group. Using a 3D imaging system in LRP may have only limited advantages in decreasing operation times over 2D imaging systems. However, the 3D system increased surgical feasibility and decreased surgeons' effort levels without inducing significant fatigue.

Laparoscopic radical prostatectomy by extraperitoneal access with duplication of the open technique

M. Tobias-Machado

2004-06-01

Full Text Available INTRODUCTION: The laparoscopic radical prostatectomy is a continually developing technique. Transperitoneal access has been preferred by the majority of centers that employ this technique. Endoscopic extraperitoneal access is used by a few groups, nevertheless it is currently receiving a higher acceptance. In general, the antegrade technique is used, with dissection from the bladder neck to the prostate apex. The objective of the present paper is to describe the extraperitoneal technique with reproduction of the open surgery's surgical steps. SURGICAL TECHNIQUE: With this technique, the dissection of the prostate apex is performed and, following the section of the urethra while preserving the sphincteric apparatus, the Foley catheter is externally tied and internally recovered, which allows cranial traction, similarly to the way it is performed in conventional surgery. The retroprostatic space is posteriorly dissected and the seminal vesicles are identified by anterior and posterior approach, obtaining with this method an optimal exposure of the posterolateral pedicles and the prostate contour. The initial impression is that this technique does not present higher bleeding rate or difficulty level when compared with antegrade surgery. Potential advantages of this technique would be the greater familiarity with surgical steps, isolated extraperitoneal drainage of urine and secretions and a good definition of prostate limits and lateral pedicles, which are critical factors for preserving the neurovascular bundles and avoiding positive surgical margins. A higher number of cases and a long-term follow-up will demonstrate its actual value as a technical option for endoscopic access to the prostate.

Optic nerve sheath diameter remains constant during robot assisted laparoscopic radical prostatectomy.

Full Text Available During robot assisted laparoscopic radical prostatectomy (RALRP, a CO2 pneumoperitoneum (CO2PP is applied and the patient is placed in a head-down position. Intracranial pressure (ICP is expected to acutely increase under these conditions. A non-invasive method, the optic nerve sheath diameter (ONSD measurement, may warn us that the mechanism of protective cerebrospinal fluid (CSF shifts becomes exhausted.After obtaining IRB approval and written informed consent, ONSD was measured by ocular ultrasound in 20 ASA I-II patients at various stages of the RALRP procedure: baseline awake, after induction, after applying the CO2PP, during head-down position, after resuming the supine position, in the postoperative anaesthesia care unit, and on day one postoperatively. Cerebral perfusion pressure (CPP was calculated as the mean arterial (MAP minus central venous pressure (CVP.The ONSD did not change during head-down position, although the CVP increased from 4.2(2.5 mm Hg to 27.6(3.8 mm Hg. The CPP was decreased 70 min after assuming the head-down position until 15 min after resuming the supine position, but remained above 60 mm Hg at all times.Even though ICP has been documented to increase during CO2PP and head-down positioning, we did not find any changes in ONSD during head-down position. These results indicate that intracranial blood volume does not increase up to a point that CSF migration as a compensation mechanism becomes exhausted, suggesting any increases in ICP are likely to be small.

Herein, we describe several steps to improve surgeon autonomy during a Left Robotic-Assisted Laparoscopic Radical Nephrectomy (RALRN), using the Da Vinci Si system. Our kidney cancer program is based on 2 community hospitals. We use the Da Vinci Si system. Access is obtained with the following trocars: Two 8 mm robotic, one 8 mm robotic, bariatric length (arm 3), 15 mm for the assistant and 12 mm for the camera. We use curved monopolar scissors in robotic arm 1, Bipolar Maryland in arm 2, Prograsp Forceps in arm 3, and we alternate throughout the surgery with EndoWrist clip appliers and the vessel sealer. Here, we described three steps and the use of 3 robotic instruments to improve surgeon autonomy. Step 1: the lower pole of the kidney was dissected and this was retracted upwards and laterally. This maneuver was performed using the 3rd robotic arm with the Prograsp Forceps. Step 2: the monopolar scissors was replaced (robotic arm 1) with the robotic EndoWrist clip applier, 10 mm Hem-o-Lok. The renal artery and vein were controlled and transected by the main surgeon. Step 3: the superior, posterolateral dissection and all bleeders were carefully coagulated by the surgeon with the EndoWrist one vessel sealer. We have now performed 15 RALRN following these steps. Our results were: blood loss 300 cc, console time 140 min, operating room time 200 min, anesthesia time 180 min, hospital stay 2.5 days, 1 incisional hernia, pathology: (13) RCC clear cell, (1) chromophobe and (1) papillary type 1. Tumor Stage: (5) T1b, (8) T2a, (2) T2b. We provide a concise, step-by-step technique for radical nephrectomy (RN) using the Da Vinci Si robotic system that may provide more autonomy to the surgeon, while maintaining surgical outcome equivalent to standard laparoscopic RN.

To describe the first series of robot-assisted laparoscopic radical prostatectomy (RALP) using the ALEXIS™ trocar device when removal of the specimen is necessary for intraoperative frozen-section pathology. Consecutive RALP using the ALEXIS were prospectively catalogue. Perioperative data, including preoperative oncologic diagnosis, operative time, estimated blood loss (EBL), size of incision for umbilical trocar, complications related to trocar, and length of hospital stay, were analyzed. One hundred twenty-eight patients were analyzed. The mean operative time was 216 minutes, mean time to trocar placement was 4 minutes, and mean EBL was 172 mL. The incision size for a trocar was 2-3 cm in 117 patients and 1 incisional hernia was observed. The mean hospital stay was 3 days and mean follow-up was 4 months. The ALEXIS trocar provides an easy and fast intraoperative removal of the specimen for frozen pathology during RALP, even for large prostates. Safe and cosmetic results with a low intraoperative complication rate are acquired with the wound retractor.

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.

With the introduction of total mesorectal excision (TME) for treatment of rectal cancer, the prognosis of patients with rectal cancer is improved. With this better prognosis, there is a growing awareness about the quality of life of patients after rectal carcinoma. Laparoscopic total mesorectal excision (LTME) for rectal cancer offers several advantages in comparison with open total mesorectal excision (OTME), including greater patient comfort and an earlier return to daily activities while preserving the oncologic radicality of the procedure. Moreover, laparoscopy allows good exposure of the pelvic cavity because of magnification and good illumination. The laparoscope seems to facilitate pelvic dissection including identification and preservation of critical structures such as the autonomic nervous system. The technique for laparoscopic autonomic nerve preserving total mesorectal excision is reported. A three- or four-port technique is used. Vascular ligation, sharp mesorectal dissection and identification and preservation of the autonomic pelvic nerves are described.

To evaluate small intestinal submucosa (SIS), unseeded or seeded, as a possible augmentation material in a canine model of subtotal cystectomy. In all, 22 male dogs had a 90% partial cystectomy and were then divided into three groups. At 1 month after the initial cystectomy, dogs in group 1 (unseeded, six) and group 2 (seeded, six) received a bladder augmentation with a corresponding SIS graft. The dogs in group 3 (ten) received no further surgery and were considered the surgical control group. All dogs were evaluated before and after surgery with blood chemistry, urine culture, intravenous urography, cystograms and cystometrograms. After surgery (at 1, 5 and 9 months), the bladders were examined using routine histology and immunohistochemistry. All 22 dogs survived the subtotal cystectomy, and 18 survived their intended survival period. One dog, in group 2 (seeded), was killed at 1 month after augmentation due to bladder perforation caused by a large piece of incompletely absorbed SIS. Three other dogs (group 1, two; and group 2, one) were killed within 2 months after augmentation due to bladder obstruction by stones. Group 1 and group 2 SIS grafts had moderate to heavy adhesion, graft shrinkage, and some had bone and calcification at the graft site. Histologically, there was limited bladder regeneration in both groups. Interestingly, dogs in group 3 at 1 month after cystectomy (when group 1 and 2 received their augmentations) had severely shrunken bladders and histologically had severe inflammation, fibroblast infiltration and muscle hypertrophy. These results verify the subtotal cystectomy model. The use of seeded or unseeded SIS in a subtotal cystectomy model does not induce the same quality and quantity of bladder regeneration that is seen in the 40% non-inflammatory cystectomy model. This study provides important insights into the process of regeneration in a severely damaged bladder. The results led us to re-evaluate the critical elements required for a

Purpose: To determine the role of laparoscopic lymphadenectomy (pelvis ± para-aortic nodes) and laparoscopic hysterectomy in cervical cancer compared to 'classic radical surgery' in patients undergoing surgery in comparison with modern imaging in patients treated with radiotherapy alone.Materials and methods: The limitations of modern imaging are presented as well as how complication rates can be increased when classic laparotomy is followed by radiation therapy.Laparoscopic procedures are described with particular emphasis on how to provide information on lymph node metastases with the risk of overlooking microscopic involvement. A number of clinical experiences are cited to illustrate this problem and show how treatment approaches can be adapted.Results: The role of laparoscopy is evaluated according to different clinical situations and treatment protocols emphasizing the possibilities offered by this method to the radiotherapist. Conclusion: When developing laparoscopic techniques for the management of cervical carcinoma, caution must be exercised to ensure that these techniques are not detrimental to the prognosis.

To help preserve accessory pudendal arteries (APAs) and to ensure optimal postoperative sexual function after a laparoscopic or robot-assisted radical prostatectomy, we have evaluated the incidence of APAs as detected on multidetector-row CT (MDCT) angiography and have provided a detailed anatomical description. The distribution of APAs was evaluated in 121 consecutive male patients between February 2006 and July 2007 who underwent 64- channel MDCT angiography of the lower extremities. We defined an APA as any artery located within the periprostatic region running parallel to the dorsal vascular complex. We also subclassified APAs into lateral and apical APAs. Two radiologists retrospectively evaluated the origin, course and number of APAs; the final APA subclassification based on MDCT angiography source data was determined by consensus. We identified 44 APAs in 36 of 121 patients (30%). Two distinct varieties of APAs were identified. Thirty-three APAs (75%) coursed near the anterolateral region of the prostatic apex, termed apical APAs. The remaining 11 APAs (25%) coursed along the lateral aspect of the prostate, termed lateral APAs. All APAs originated from the internal obturator artery and iliac artery or a branch of the iliac artery such as the inferior vesical artery. The majority of apical APAs arose from the internal obturator artery (84%). Seven patients (19%) had multiple APAs. APAs are more frequently detected by the use of MDCT angiography than as suggested by previous surgical studies. The identification of APAs on MDCT angiography may provide useful information for the surgical preservation of APAs during a laparoscopic or robot-assisted radical prostatectomy

Aim of the present study is to determine the effects of bipolar electrocoagulation and intracorporeal suture on the ovarian reserve after ovarian cystectomy. Sixty patients aged 18-42 years old and with a persistent adnexal mass were recruited to the study. Patients were randomized into suture hemostasis group or bipolar hemostasis group. Laparoscopic ovarian cystectomy was performed to all patients. Hemostasis was obtained by bipolar coagulation in 30 patients and by intracorporeal sutures in 30 patients. Serum levels of FSH, LH, estradiol, inhibin B and ultrasonographic measurements (antral follicle count and ovarian volume) were analyzed and recorded at day 3 of menstrual cycle, 1 and 3 months after the surgery. Basal FSH level measurement at the postoperative third month was significantly increased to 6.96 ± 1.86 mIU/ml (p electrocoagulation group. However, the decreased ovarian volume and antral follicle count was restored at the postoperative third month in the bipolar electrocoagulation group. Preoperative and postoperative FSH, LH, estradiol and inhibin B levels and ultrasonographic measurements were similar in the intracorporeal suture group. The unwanted effect of bipolar electrocoagulation on ovarian reserve is probably transient and causes minimal damage to ovary. FSH levels may be slightly elevated. Gentle use of bipolar electrocoagulation or intracorporeal are not found to effect ovarian reserve.

Effect of serum testosterone and percent tumor volume on extra-prostatic extension and biochemical recurrence after laparoscopic radical prostatectomy

Full Text Available Several studies have revealed that the preoperative serum testosterone and percent tumor volume (PTV predict extra-prostatic extension (EPE and biochemical recurrence (BCR after radical prostatectomy. This study investigated the prognostic significance of serum testosterone and PTV in relation to EPE and BCR after laparoscopic radical prostatectomy (LRP. We reviewed 520 patients who underwent LRP between 2004 and 2012. PTV was determined as the sum of all visually estimated tumor foci in every section. BCR was defined as two consecutive increases in the postoperative prostate-specific antigen (PSA >0.2 ng ml−1 . The threshold for serum total testosterone was 3.0 ng ml−1 . Multivariate logistic regression was used to define the effect of variables on the risk of EPE and BCR. A low serum testosterone (<3.0 ng ml−1 was associated with a high serum PSA, Gleason score, positive core percentage of the prostate biopsy, PTV, and all pathological variables. On multivariate analysis, similar to previous studies, the serum PSA, biopsy positive core percentage, Gleason score, and pathological variables predicted EPE and BCR. In addition, low serum testosterone (<3.0 ng ml−1 , adjusted OR, 8.52; 95% CI, 5.04-14.4, P= 0.001 predicted EPE and PTV (adjusted OR, 1.02; 95% CI, 1.01-1.05, P= 0.046 predicted BCR. In addition to previous predictors of EPE and BCR, low serum testosterone and PTV are valuable predictors of EPE and BCR after LRP.

Planned pre-operative irradiation and cystectomy for selected patients with bladder cancer was initiated approximately 20 years ago by a number of centres on the basis of the disappointing end results of treatment of bladder cancer by either irradiation or surgery and the empirical hope that the combination might lead to better results. This is a brief review of the logical basis for integrated treatment and of the Memorial Sloan-Kettering Cancer Center (MSKCC) experience with such therapy. (author)

A gastrosplenic fistula is a rare complication of a gastric or splenic lesion. We report a case of Hodgkin's lymphoma (nodular sclerosis) involving the spleen that was complicated by spontaneous gastrosplenic fistula. The fistula was closed laparoscopically and the patient underwent partial gastrectomy and gastric wall repair followed by successful chemotherapy. This is also the first reported case in published literature where the closure of gastrosplenic fistula and partial gastrectomy was carried out laparoscopically. We recommend that extensive open surgical procedures including total gastroectomy, splenectomy and pancreatectomy may be avoided in the management of gastrosplenic fistula and the patient could be managed by less radical, simple laparoscopic fistulectomy, with partial gastric resection. If the fistula is caused by a malignant process, the surgical repair should be followed by definitive treatment with chemotherapy and radiotherapy. (author)

To assess the impact of lateral view apical dissection in laparoscopic radical prostatectomy (LRP) on the reduction of positive surgical margin rates and recovery of postoperative continence. One hundred and forty-four consecutive patients underwent LRP from October 2004 to March 2008. Lateral view dissection of the prostato-urethral junction was conducted in 76 of them (Group 2). Standard dissection was used in the remaining patients (Group 1). The effect of this technical modification on the reduction of positive surgical margin rates and postoperative recovery of urinary continence was assessed in the two groups. Overall, the incidence of positive margins decreased from 23 (35.9%) in Group 1 to 16 cases (21.9%) in Group 2 (P = 0.07). Positive margin rates in pT2 decreased from 30.6% to 6.5% (P = 0.006). Apical and dorso-apical margins were reduced from 26.5% to 4.3% (P = 0.009) and from 10.2% to 0% (P Lateral view dissection of the prostato-urethral junction is an easily applicable technical modification. It provides better visualization of apical anatomy substantially contributing to the reduction of positive surgical margin rates, especially at the level of prostatic apex.

Objective Anastomotic complications are well known after radical prostatectomy (RP). The vesicourethral anastomotic technique is handled differently between open and robotic RP. The aim of the study was to investigate whether the frequency of anastomotic leakages and strictures differed between...... patients undergoing retropubic radical prostatectomy (RRP) and robot-assisted radical prostatectomy (RARP) and to identify risk factors associated with these complications. Materials and methods The study included 735 consecutive patients who underwent RRP (n = 499) or RARP (236) at the Department...... of Urology, Rigshospitalet, Denmark, in a complete 3 year period from 2010 to 2012. Univariate and multivariate logistic regression analysis was used to analyse associations between surgical procedure (RRP vs RARP) and anastomotic complications. Analyses included age, smoking status, diabetes, hypertension...

Robot-assisted laparoscopic radical prostatectomy (RALRP) is commonly performed in the surgical treatment of prostate cancer. However, the steep Trendelenburg position (25) and pneumoperitoneum required for this procedure can sometimes cause hemodynamic changes. Although blood pressure is traditionally monitored invasively during RALRP, the ClearSight system (BMEYE, Amsterdam, The Netherlands) enables a totally noninvasive and simple continuous blood pressure and cardiac output monitoring based on finger arterial pressure pulse contour analysis. We therefore investigated whether noninvasive continuous arterial blood pressure measurements using the ClearSight system were comparable to those obtained invasively in patients undergoing RALRP. Ten patients scheduled for RALRP with American Society of Anesthesiologists physical status I-II were included in this study. At each of the seven defined time points, noninvasive and invasive blood pressure measurements were documented and compared in each patient using Bland-Altman analysis. Although the blood pressure measured with the ClearSight system correlated with that measured invasively, a large difference between the values obtained by the two devices was noted. The ClearSight system was unable to detect blood pressure accurately during RALRP, suggesting that blood pressure monitoring using this device alone is not feasible in this small patient population.

Robot-assisted laparoscopic radical prostatectomy (RALRP) is successfully being performed for treating prostate cancer (PCa). However, instrumentation failure associated with robotic procedures represents a unique new problem. We report the successful completion of RALRP in spite of a disassembled hand piece spring during the procedure. A PubMed/Medline search was made concerning robotic malfunction and robot-assisted laparoscopic radical prostatectomy to discuss our experience. We performed RALRP in a 60-year-old male patient with localized PCa. During the procedure, the spring of the hand piece disassembled, and we were not able to reassemble it. We completed the procedure successfully however without fixing the disassembled hand piece spring. We were able to grasp tissue and needles when we brought our fingers together. The only movement we needed to do was to move fingers apart to release tissue or needles caught by robotic instrument. Although malfunction risk related to the da Vinci Surgical System seems to be very low, it might still occur. Sometimes, simple maneuvers may compensate for the failed function as occurred in our case. However, patients should be informed before the operation about the possibility of converting their procedure to laparoscopic or open due to robotic malfunction.

We investigated the outcomes and quality of life measures in men who underwent cystectomy and urinary diversion for devastating lower urinary tract toxicity after prostatic radiotherapy and/or cryotherapy for the treatment of prostate cancer. Records of patients who underwent cystectomy and urinary diversion for the management of a devastated lower urinary tract following prostatic radiotherapy or cryotherapy were reviewed retrospectively. A postoperative, retrospective quality of life (QOL) survey was designed specific to this patient subset and obtained by telephone interview. Extirpative surgery with urinary diversion for management of a devastated lower urinary tract was performed on 15 patients with a mean age of 72 years (range 63-82). Toxicities leading to bladder removal included bladder neck contractures, prostatic necrosis, incontinence, osteomyelitis, bladder calculi, fistulae, urethral strictures, abscesses, necrotizing fasciitis, and radiation/hemorrhagic cystitis. The mean number of failed conservative, minimally invasive interventions per patients prior to cystectomy was 3.7 (range 1-12). The average time period from major complication following radiotherapy/cryotherapy to cystectomy was 29.1 months (range 5-65). The QOL survey showed all of the patients who completed the survey (n = 13) would undergo the procedure again and 11 (85%) would have undergone the procedure an average of 13.2 months sooner (range 5-36). Toxicities secondary to prostatic radiotherapy or cryotherapy may be debilitating. Our results demonstrate that cystectomy with urinary diversion can improve QOL in patients with a devastated lower urinary tract.

Chemoradiotherapy as a bladder-preservation approach for muscle-invasive bladder cancer. Current status and perspectives

International Nuclear Information System (INIS)

Sumiyoshi, Yoshiteru

2004-01-01

Radical cystectomy has been considered the (gold standard for the treatment of muscle-invasive bladder r cancer. However, because of disappointing results with radical surgery in terms of survival and decreased quality of life (QOL), bladder-preservation treatment has been introduced as an alternative to radical cystectomy. The primary purpose of the bladder-preservation approach has been to maximize overall cure rates, with the secondary purpose being to preserve the patient's bladder. The modalities used to ensure successful bladder preservation include radical transurethral resection (TUR), concurrent cisplatin (CDDP)-based chemotherapy, and radiotherapy. In patients who achieve a complete response (CR) after trimodality therapy, 5-year survival rates of more than 50%, the same as those of radical cystectomy, can be achieved and 70% of this group will retain an intact functional bladder. In this article, bladder-preservation studies using chemoradiotherapy are reviewed. (author)

Compared to laparotomic surgery, laparoscopically assisted radical vaginal hysterectomy (LARVH) offers decreased blood loss during surgery and faster convalescence of the patient postoperatively, while at the same time delivering similar oncologic results. However, there is no data on outcome and toxicity of LARVH followed by (chemo)radiation. A total of 55 patients (range 28-78 years) with cervical cancer on FIGO stages IB1-IIIA (Tables 1 and 2) with risk factors were submitted to either external beam radiotherapy alone [EBRT, n = 8 (14%), including paraaortic irradiation, n = 4 (2.2%); EBRT and brachytherapy (BT), n = 33 (60%); BT alone, n = 14 (25.5%)] or chemoradiation after LARVH. At a median follow-up of 4.4 years, the 5-year disease-free survival (DFS) was 81.8% with 84.5% overall survival (OS). Acute grade 3 side effects were seen in 4 patients. These were mainly gastrointestinal (GI) and genitourinary (GU) symptoms. Grade 4 side effects were not observed. With similar oncologic outcome data and mostly mild side effects, LARVH followed by (chemo)radiation is a valid alternative in the treatment of cervical cancer patients. (orig.)

We conducted a questionnaire survey of hospitals with robot-assisted surgical equipment to study changes of the surgical case loads after its installation and the managerial strategies for its purchase. The study included 154 hospitals (as of April 2014) that were queried about their radical prostatectomy case loads from January 2009 to December 2013, strategies for installation of the equipment in their hospitals, and other topics related to the study purpose. The overall response rate of hospitals was 63%, though it marginally varied according to type and area. The annual case load was determined based on the results of the questionnaire and other modalities. It increased from 3,518 in 2009 to 6,425 in 2013. The case load seemed to be concentrated in hospitals with robot equipment since the increase of their number was very minimal over the 5 years. The hospitals with the robot treated a larger number of newly diagnosed patients with the disease than before. Most of the patients were those having localized cancer that was indicated for radical surgery, suggesting again the concentration of the surgical case loads in the hospitals with robots. While most hospitals believed that installation of a robot was necessary as an option for treatment procedures, the future strategy of the hospital, and other reasons, the action of the hospital to gain prestige may be involved in the process of purchasing the equipment. In conclusion, robot-assisted laparoscopic radical prostatectomy has become popular as a surgical procedure for prostate cancer in our society. This may lead to a concentration of the surgical case load in a limited number of hospitals with robots. We also discuss the typical action of an acute-care hospital when it purchases expensive clinical medical equipment.

Laparoscopic surgery (LS), also referred to as minimally invasive surgery, is a modern surgical technique which is widely applied. The fulcrum effect makes LS a non-intuitive motor skill with a steep learning curve. A hybrid model of tetrahedrons and a multi-layer triangular mesh are constructed to simulate the deformable behavior of the rectum and surrounding tissues in the Position-Based Dynamics (PBD) framework. A heat-conduction based electric-burn technique is employed to simulate the electrocautery procedure. The simulator has been applied for laparoscopic rectum cancer surgery training. From the experimental results, trainees can operate in real time with high degrees of stability and fidelity. A preliminary study was performed to evaluate the realism and usefulness. This prototype simulator has been tested and verified by colorectal surgeons through a pilot study. They believed both the visual and the haptic performance of the simulation are realistic and helpful to enhance laparoscopic skills. Copyright © 2017 John Wiley & Sons, Ltd.

Bladder cancer (UCB) staged pT4a show heterogeneous outcome after radical cystectomy (RC). No risk model has been established to date. Despite gender-specific differences, no comparative studies exist for this tumor stage. Cancer-specific survival (CSS) of 245 UCB patients without neoadjuvant chemotherapy staged pT4a, pN0-2, M0 after RC were analyzed in a retrospective multi-center study. Seventeen patients were excluded from further analysis due to carcinoma in situ (CIS) of the prostatic urethra and/or positive surgical margins. Average follow-up period was 30 months (IQR: 14-45). The influence of different clinical and histopathologic variables on CSS was determined through uni- and multivariate Cox regression analyses. Two risk groups were generated using factors with independent effect in multivariate models. Internal validity of the prediction model was evaluated by bootstrapping. Eighty-four percent of the patients (n = 192) were male; 72% (n = 165) showed lymphovascular invasion (LVI). The 5-year CSS rate was 31%, and significantly different between male and female (35% vs. 15%, P = 0.003). Multivariate Cox regression modeling, female gender (HR = 1.83, P = 0.008), LVI (HR = 1.92, P = 0.005), and absence of adjuvant chemotherapy (HR = 0.61, P = 0.020) significantly worsened CSS. Two risk groups were generated using these 3 criteria, which differed significantly between each other in CSS (5-year-CSS: 46% vs. 12%, P < 0.001). The c-index value of the risk model was 0.61 (95% CI: 0.53-0.68, P < 0.001). Prognosis in UCB staged pT4a is heterogeneous. Female gender and LVI are adverse factors. Adjuvant chemotherapy seems to improve outcome. The present analysis establishes the first risk model for this demanding tumor stage. Copyright © 2013 Elsevier Inc. All rights reserved.

Study Type-Prognosis (cohort) Level of Evidence 2a. What's known on the subject? and What does the study add? Radical cystectomy with pelvic lymph node dissection is recognized as the standard of care for carcinoma invading bladder muscle and for refractory non-muscle-invasive bladder cancer. Owing to high recurrence and progression rates, a two-pronged strict surveillance regimen, consisting of both functional and oncological follow-up, has been advocated. It is also well recognized that more aggressive tumours with extravesical disease and node-positive disease recur more frequently and have worse outcomes. This study adds to the scant body of literature available regarding surveillance strategies after radical cystectomy for bladder cancer. In the absence of any solid evidence supporting the role of strict surveillance regimens, this extensive examination of recurrence patterns in a large multi-institutional project lends further support to the continued use of risk-stratified follow-up and emphasizes the need for earlier strict surveillance in patients with extravesical and node-positive disease. To review our data on recurrence patterns after radical cystectomy (RC) for bladder cancer (BC). To establish appropriate surveillance protocols. We collected and pooled data from a database of 2287 patients who had undergone RC for BC between 1998 and 2008 in eight different Canadian academic centres. Of the 2287 patients, 1890 had complete recurrence information and form the basis of the present study. A total of 825 patients (43.6%) developed recurrence. According to location, 48.6% of recurrent tumours were distant, 25.2% pelvic, 14.5% retroperitoneal and 11.8% to multiple regions such as pelvic and retroperitoneal or pelvic and distant. The median (range) time to recurrence for the entire population was 10.1 (1-192) months with 90 and 97% of all recurrences within 2 and 5 years of RC, respectively. According to stage, pTxN+ tumours were more likely to recur than p

Distal pancreatectomy is the standard curative treatment for symptomatic benign, premalignant, and malignant disease of the pancreatic body and tail. The most obvious benefits of a laparoscopic approach to distal pancreatectomy include earlier recovery and shorter hospital stay. Spleen-preserving distal pancreatectomy should be attempted in case of benign disease. Spleen preservation can be achieved preferably by preserving the splenic vessels (Kimura technique), but also by resecting the splenic vessels and maintaining vascularity through the short gastric vessels and left gastroepiploic artery (Warshaw technique). Several studies have suggested a higher rate of spleen preservation with laparoscopy. The radical antegrade modular pancreatosplenectomy has become mainstay for treating pancreatic cancer and can be performed laparoscopically as well. Evidence on the feasibility and safety of laparoscopic distal pancreatectomy for cancer is scarce. Despite the obvious advantages of laparoscopic surgery, postoperative morbidity remains relatively high, mainly because of the high incidence of pancreatic fistula. For decades, surgeons have tried to prevent these fistulas but to date no strategy has been confirmed to be effective in 2 consecutive randomized studies. Pragmatic multicenter studies focusing on technical aspects of laparoscopic distal pancreatectomy are lacking and should be encouraged. PMID:26240565

We assessed the feasibility of a laparoscopic sentinel node (SN) procedure based on the combined use of radiocolloid and patent blue labeling in patients with endometrial cancer. Seventeen patients (median age, 69 years) with endometrial cancer of stage I (16 patients) or stage II (1 patient) underwent a laparoscopic SN procedure based on combined radiocolloid and patent blue injected pericervically. After the SN procedure, all patients underwent complete laparoscopic pelvic lymphadenectomy and either laparoscopically assisted vaginal hysterectomy (16 patients) or laparoscopic radical hysterectomy (1 patient). SNs (mean number per patient, 2.6; range, 1-4) were identified in 16 (94.1%) of the 17 patients. Macrometastases were detected in three SNs from two patients by hematoxylin and eosin staining. In three other patients, immunohistochemical analysis identified six micrometastatic SNs and one SN containing isolated tumor cells. No false-negative SN results were observed. An SN procedure based on a combination of radiocolloid and patent blue is feasible in patients with early endometrial cancer. Combined use of laparoscopy and this SN procedure permits minimally invasive management of endometrial cancer.

We report 2 cases of laparoscopic surgery for patients who had liver abscess as the initial manifestation of underlying colon cancer. The first case was in an 80-year-old woman who presented to our hospital with a diagnosis ofliver abscess. Percutaneous transhepatic abscess drainage(PTAD)was performed as initial treatment. Subsequent colonoscopy revealed a type 1 tumor in the cecum, and biopsy results ofthe mass indicated adenocarcinoma. The patient underwent laparoscopic right hemicolectomy as curative treatment. The pathological findings were as follows: tub1, T2, N0, M0 and Stage I . Two years later, she remains disease free. The second case was in a 59-year-old man with liver abscess. Colonoscopy also revealed a type 2 tumor in the sigmoid colon. After treatment of the liver abscess with PTAD, laparoscopic sigmoidectomy was performed with a preoperative diagnosis of sigmoid colon cancer. The pathological findings were as follows: tub2, T3, N0, M0 and Stage II . Lung metastases appeared 10 months after surgery, and systemic chemotherapy was administered. In conclusion, liver abscess is occasionally caused by malignancy, and complete gastrointestinal evaluation should be conducted. Laparoscopic radical surgery can be safely performed in cases in which the liver abscesses are controlled.

A Case Series of Patients Who Underwent Laparoscopic Extraperitoneal Radical Prostatectomy with the Simultaneous Implant of a Penile Prosthesis: Focus on Penile Length Preservation

Purpose There are many grey areas in the field of penile rehabilitation after radical prostatectomy (RP). The preservation of the full dimensions of the penis is an important consideration for improving patients' compliance for the treatment. We present the first case series of patients treated by laparoscopic extraperitoneal RP and simultaneous penile prosthesis implantation (PPI) in order to preserve the full length of the penis and to improve patients' satisfaction. Materials and Methods From June 2013 to June 2014, 10 patients underwent simultaneous PPI (with an AMS InhibiZone prosthesis) and RP. Patients were evaluated by means of urological visits, questionnaires, and objective measurements before surgery, at discharge from the hospital, on postoperative days 21 to 28, each 3 months for the first year, and each 6 months thereafter. The main outcome measures were biochemical recurrence-free rate, penile length, and quality of life. Results Ten patients (mean age of 61 years; completed the study follow-up period (median, 32.2 months). No difference was found between the time of surgery and the 2-year follow-up evaluation in terms of penile length. The pre-surgery 36-Item Short Form Health Survey (SF-36) median score was 97. Patients were satisfied with their penile implants, and couples' level of sexual satisfaction was rated median 8. The median postoperative SF-36 score was 99 at 3 months follow-up. Conclusions Laparoscopic extraperitoneal RP surgery with simultaneous PPI placement seems to be an interesting possibility to propose to motivated patients for preserving the length of the penis and improving their satisfaction.

Preoperative staging of bladder cancer using imaging methods has serious limitations. The accuracy of the abdominal diffusion-weighted magnetic resonance (DW-MRI) to predict residual muscle invasion, perivesical and/or lymph node affectation in the cystectomy specimen is evaluated. A prospective study was performed on 20 patients with high grade muscle invasive bladder cancer who received transurethral resection of the bladder (TURB) in a period of bladder TURB. Furthermore, the ADC coefficient also predicts tumor differentiation grade. Copyright © 2013 AEU. Published by Elsevier Espana. All rights reserved.

Radical cystectomy (RC with lymph-node dissection is the standard treatment of muscle-invasive bladder cancer and high-risk noninvasive bladder cancer. A wide range of impairments are reported postsurgery. The aims were to evaluate whether a standardized pre- and postoperative physical exercise program and enhanced mobilization can impact on HRQoL and inpatient satisfaction in RC, as defined by the European Organisation for Research and Treatment of Cancer (EORTC. Materials and methods: Patients were randomized to fast-track RC and intervention (nI=50 or fast-track standard treatment (ns=57. HRQoL and inpatient satisfaction was measured using valid questionnaires: EORTC Quality of Life Questionnaire Core 30 (QLQ-C30 combined with the disease-specific EORTC BLS24 (baseline, and EORTC BLM30 (follow-up, and IN-PATSAT32 inpatient-satisfaction survey at discharge. Efficacy was defined as the differences in HRQoL-scores between treatment groups at the 4-month follow-up. Results: The intervention group significantly improved HRQoL scores in dyspnea (P≤0.05, constipation (P<0.02, and abdominal flatulence (P≤0.05 compared to the standard group. In contrast, the standard group reported significantly reduced symptoms in sleeping pattern (P≤0.04 and clinically relevant differences in role function, body function, and fatigue. The intervention did not compromise inpatient satisfaction. Conclusion: We found no overall impact

Full Text Available Objectives: Ongoing with the newer developments in laparoscopic radical prostatectomy (LRP, we report our experience in a consecutive series of 42 patients with a mean 18-month follow-up. We also studied the use of a low-energy source, especially in the region of the prostatic apex and the neurovascular bundle and evaluated its outcome on continence and potency. Materials and Methods: Between November 2003 and December 2008, 50 patients aged 50-80 yrs underwent LRP with vesicourethral anastomosis and of these, 42 patients who had a minimum follow-up of 3 months were selected for the study. Of these, the initial 16 patients were operated by the routine method and the 26 patients operated in the later part of our experience were operated upon using a minimal energy source. Results: The mean follow-up was 18 months (range 3-60. Continence was evaluated at 1, 3, 6, and 12 months. Eleven of the 16 patients in Group I were continent as compared with 21 of 26 patients in Group II. The difference in continence rates was mainly due to less use of electrocautery and harmonic scalpel at the bladder neck. Of the eight patients who were potent pre-operatively in Group I, four remained potent 3 months after LRP. In Group II, 20 of the 26 patients were potent pre-operatively and 16 remained potent 3 months after LRP. Conclusions: Use of a low-energy source at the bladder neck and neurovascular bundle, sparing of seminal vesicle, and leaving behind a long, healthy stump of the urethra during apical dissection, is associated with better continence and potency without compromising oncological outcome.

Radiofrequency has been used as a tool for liver resection since 2002. A new laparoscopic device is reported in this article that assists liver resection laparoscopically. From October 2006 to the present, patients suitable for liver resection were assessed carefully for laparoscopic resection with the laparoscopic Habib Sealer (LHS). Detailed data of patients resected laparoscopically with this device were collected prospectively and analyzed. In all, 28 patients underwent attempted laparoscopic liver resection. Four cases had to be converted to an open approach because of extensive adhesions from previous colonic operations. Twenty-four patients completed the procedure comprising tumorectomy (n = 7), multiple tumoretcomies (n = 5), segmentectomy (n = 3), and bisegmentectomies (n = 9). Vascular clamping of portal triads was not used. The mean resection time was 60 +/- 23 min (mean +/- SD), and blood loss was 48 +/- 54 mL. None of the patients received any transfusion of blood or blood products perioperatively or postoperatively. Postoperatively, 1 patient developed severe exacerbation of asthma that required steroid therapy, and 1 other patient had a transient episode of liver failure that required supportive care. The mean duration of hospital stay was 5.6 +/- 2 days (mean +/- SD). At a short-term follow up, no recurrence was detected in patients with liver cancer. Laparoscopic liver resection can be performed safely with this new laparoscopic liver resection device with a significantly low risk of intraoperative bleeding or postoperative complications.

Full Text Available PURPOSE: Radical nephrectomy can be performed using open or laparoscopic (with or without hand assistance methods, and most recently using the da Vinci Surgical Robotic System. We evaluated the perioperative outcomes using a contemporary cohort of patients undergoing radical nephrectomy by one of the above 4 methods performed by the same surgeon. MATERIALS AND METHODS: The relevant clinical information on 57 consecutive patients undergoing radical nephrectomy from September 2000 until July 2004 by a single surgeon was entered in a Microsoft Access DatabaseTM and queried. Following appropriate statistical analysis, p values < 0.05 were considered significant. RESULTS: Of 57 patients, the open, robotic, laparoscopy with or without hand assistance radical nephrectomy were performed in 18, 6, 21, and 12 patients, respectively. The age, sex, body mass index (BMI, incidence of malignancy, specimen and tumor size, tumor stage, Fuhrman grade, hospital stay, change in postoperative creatinine, drop in hemoglobin, and perioperative complications were not significantly different between the methods. While the estimated median blood loss, postoperative narcotic use for pain control, and hospital stay were significantly higher in the open surgery method (p < 0.05, the median operative time was significantly shorter compared to the robotic method (p = 0.02. Operating room costs were significantly higher in the robotic and laparoscopic groups; however, there was no significant difference in total hospital costs between the 4 groups. CONCLUSIONS: The study demonstrates that radical nephrectomy can be safely performed either by open, robotic, or laparoscopic with or without hand assistance methods without significant difference in perioperative complication rates. A larger cohort and longer follow up are needed to validate our findings and establish oncological outcomes.

Full Text Available Abstract Background The purpose of this clinical study is to evaluate the feasibility of using 2-mm laparoscopic instruments to perform an appendectomy in patients with clinically suspected acute appendicitis and compare the outcome of this mini-laparoscopic or "needlescopic" approach to the conventional laparoscopic appendectomy. Methods Two groups of patients undergoing appendectomy over 24 months were studied. In the first group, needlescopic appendectomy was performed in 15 patients by surgeons specializing in advanced laparoscopy. These patients were compared with the second or control group that included 21 consecutive patients who underwent laparoscopic appendectomy. We compared the patients' demographic data, operative findings, complications, postoperative pain medicine requirements, length of hospital stay, and recovery variables. Differences were considered statistically significant at a p-value Results Patient demographics, history of previous abdominal surgery, and operative findings were similar in both groups. There was no conversion to open appendectomy in either group. No postoperative morbidity or mortality occurred in either group. The needlescopic group had a significantly shorter mean operative time (p = 0.02, reduced postoperative narcotics requirements (p = 0.05, shorter hospital stay (p = 0.04, and quicker return to work (p = 0.03 when compared with the laparoscopic group. Conclusions We conclude that the needlescopic technique is a safe and effective approach to appendectomy. When performed by experienced laparoscopic surgeons, the needlescopic technique results in significantly shorter postoperative convalescence and a prompt recovery.

Laparoscopic herniorrhaphy.

There is little doubt that laparoscopic herniorrhaphy has assumed a place in the pantheon of hernia repair. There is also little doubt that further work needs to be done to determine the exact role that laparoscopic hernia repair should play in the surgical armamentarium. Hernias have been surgically treated since the early Greeks. In contrast, laparoscopic hernia repair has a history of only 6 years. Even within that short time, laparoscopic hernia repair techniques have not remained unchanged. This is obviously a technique in evolution, as indicated by the abandonment of early repairs ("plug and mesh" and IPOM) and the gradual gain in pre-eminence of the TEP repair. During the same time frame, surgery itself has evolved into a discipline more concerned with cost-effectiveness, outcomes, and "consumer acceptance." Confluence of these two developments has led to a situation in which traditional concerns regarding surgical procedures (i.e., recurrence rates or complication rates) assume less of a role than cost-effectiveness, learnability, marketability, and medical-legal considerations. No surgeon, whether practicing in a academic setting or a private practice, is exempt from these pressures. Laparoscopic hernia repair therefore seems to fit into a very specialized niche. In our community, the majority of general surgeons are only too happy to not do laparoscopic hernia repairs. On the other hand, in our experience, certain indications do seem to cry out for a laparoscopic approach. At our own center we have found that laparoscopic repairs can indeed be effective, and even cost-effective, under specific circumstances. These include completing a minimal learning curve, utilizing the properitoneal approach, minimizing the use of reusable instruments, using dissecting balloons as a time-saving device, and very specific patient selection criteria. At present these include patients with bilateral inguinal hernias on clinical examination, patients with recurrent

Robotic technology disseminated into urological practice without robust comparative effectiveness data. To review the diffusion of robotic surgery into urological practice. We performed a comprehensive literature review focusing on diffusion patterns, patient safety, learning curves, and comparative costs for robotic radical prostatectomy, partial nephrectomy, and radical cystectomy. Robotic urologic surgery diffused in patterns typical of novel technology spreading among practicing surgeons. Robust evidence-based data comparing outcomes of robotic to open surgery were sparse. Although initial Level 3 evidence for robotic prostatectomy observed complication outcomes similar to open prostatectomy, subsequent population-based Level 2 evidence noted an increased prevalence of adverse patient safety events and genitourinary complications among robotic patients during the early years of diffusion. Level 2 evidence indicated comparable to improved patient safety outcomes for robotic compared to open partial nephrectomy and cystectomy. Learning curve recommendations for robotic urologic surgery have drawn exclusively on Level 4 evidence and subjective, non-validated metrics. The minimum number of cases required to achieve competency for robotic prostatectomy has increased to unrealistically high levels. Most comparative cost-analyses have demonstrated that robotic surgery is significantly more expensive than open or laparoscopic surgery. Evidence-based data are limited but suggest an increased prevalence of adverse patient safety events for robotic prostatectomy early in the national diffusion period. Learning curves for robotic urologic surgery are subjective and based on non-validated metrics. The urological community should develop rigorous, evidence-based processes by which future technological innovations may diffuse in an organized and safe manner.

Full Text Available ABSTRACT Objective: to analyze the National Cancer Institute Abdominopelvic Division (INCA / MS/HC I initial experience with thoraco-laparoscopic esophagectomy with thoracic stage in prone position. Methods: we studied 19 consecutive thoraco-laparoscopic esophagectomies from may 2012 to august 2014, including ten patients with squamous cells carcinoma (five of the middle third and five of the lower third and nine cases of gastroesophageal junction adenocarcinoma (six Siewert I and three Siewert II. All procedures were initiated by the prone thoracic stage. Results: There were minimal blood loss, optimal mediastinal visualization, oncological radicality and no conversions. Surgical morbidity was 42 %, most being minor complications (58% Clavien I or II, with few related to the technique. The most common complication was cervical anastomotic leak (37%, with a low anastomotic stricture rate (two stenosis: 10.53%. We had one (5.3% surgical related death, due to a gastric tube`s mediastinal leak, treated by open reoperation and neck diversion. The median Intensive Care Unit stay and hospital stay were two and 12 days, respectively. The mean thoracoscopic stage duration was 77 min. Thirteen patients received neoadjuvant treatment (five squamous cells carcinoma and eight gastroesophageal adenocarcinomas. The average lymph node sample had 16.4 lymph nodes per patient and 22.67 when separately analyzing patients without neoadjuvant treatment. Conclusion: the thoraco-laparoscopic approach was a safe technique in the surgical treatment of esophageal cancer, with a good lymph node sampling.

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

The purpose of the review was to evaluate the feasibility and outcome of laparoscopic pancreatic cystogastrostomy for operative drainage of symptomatic pancreatic pseudocysts. A retrospective review of all patients who underwent laparoscopic pancreatic cystogastrostomy between June 1997 and July 2001 was performed. Data regarding etiology of pancreatitis, size of pseudocyst, operative time, complications, and pseudocyst recurrence were collected and reported as median values with ranges. Laparoscopic pancreatic cystogastrostomy was attempted in 6 patients. Pseudocyst etiology included gallstone pancreatitis (3), alcohol-induced pancreatitis (2), and post-ERCP pancreatitis (1). The cystogastrostomy was successfully performed laparoscopically in 5 of 6 patients. However, the procedure was converted to open after creation of the cystgastrostomy in 1 of these patients. There were no complications in the cases completed laparoscopically and no deaths in the entire group. No pseudocyst recurrences were observed with a median followup of 44 months (range 4-59 months). Laparoscopic pancreatic cystgastrostomy is a feasible surgical treatment of pancreatic pseudocysts with a resultant low pseudocyst recurrence rate, length of stay, and low morbidity and mortality.

Purpose: To evaluate our long-term results of bladder preservation with brachytherapy in the treatment of bladder cancer. Methods and materials: Between 1987 and 2000, 108 patients with T1-G3 and T2-T3a stages of bladder cancer were treated with a transurethral resection (TUR) and a course of external beam radiotherapy (30 Gy in 15 fractions) followed by brachytherapy (40 Gy). All tumors were solitary lesions with a diameter ≤5 cm. Median follow-up was 54 months (range, 1-178 months). Results: The 5-year and 10-year overall survival rates were 62% and 50%, respectively. The 5-year and 10-year disease-specific survival rates were 73% and 67%, respectively. The actuarial local control rate was 73% at 5 and 73% at 10 years, respectively. The 5-year and 10-year disease-specific survival rates for patients with a preserved bladder were 68% and 59%, respectively. Of all long-term surviving patients, 90% preserved their native bladders. The treatment was well tolerated. Acute toxicity was mild. Two patients experienced serious late toxicity: 1 patient developed a persisting vesicocutaneous fistula and the other a stricture of the urethra and ureters. Conclusion: For patients with solitary, organ confined invasive bladder cancer ≤5 cm, bladder preservation with brachytherapy is an excellent alternative to radical cystectomy and combined modality treatment

We sought to evaluate the financial impact of robotic technology for partial nephrectomy (PN) and radical nephrectomy (RN) in the state of Maryland. The Maryland Health Services Cost Review Commission (HSCRC) documents all acute care hospital charges data. This database was queried for patients who underwent laparoscopic or robot-assisted RN and PN from 2008 to 2012. Total hospital charge, subcharge, and length of stay (LOS) were analyzed separately for RN and PN. Overall, 2834 patients were identified. Of those, 282 were laparoscopic PN (LPN), 1078 robot-assisted PN (RPN), 1098 laparoscopic RN (LRN), and 376 robot-assisted RN (RRN). For PN, the total hospital charge was $19,062 for LPN and $18,255 for RPN (P=0.138), with a charge savings of $807 per case in favor of robotics. For RN, the total hospital charge was $23,391 for RRN and $18,280 for LRN (P=0.004), with a charge premium of $5111 for robotic cases. LOS was shorter for RPN compared with LPN (2.51 vs 2.99 days, Pfinancial implications of RRN use for routine cases warrants further study.

Abstract Rationale: Laparoscopic total pancreatectomy is a complicated surgical procedure and rarely been reported. This study was conducted to investigate the safety and feasibility of laparoscopic total pancreatectomy. Patients and Methods: Three patients underwent laparoscopic total pancreatectomy between May 2014 and August 2015. We reviewed their general demographic data, perioperative details, and short-term outcomes. General morbidity was assessed using Clavien–Dindo classification and delayed gastric emptying (DGE) was evaluated by International Study Group of Pancreatic Surgery (ISGPS) definition. Diagnosis and Outcomes: The indications for laparoscopic total pancreatectomy were intraductal papillary mucinous neoplasm (IPMN) (n = 2) and pancreatic neuroendocrine tumor (PNET) (n = 1). All patients underwent laparoscopic pylorus and spleen-preserving total pancreatectomy, the mean operative time was 490 minutes (range 450–540 minutes), the mean estimated blood loss was 266 mL (range 100–400 minutes); 2 patients suffered from postoperative complication. All the patients recovered uneventfully with conservative treatment and discharged with a mean hospital stay 18 days (range 8–24 days). The short-term (from 108 to 600 days) follow up demonstrated 3 patients had normal and consistent glycated hemoglobin (HbA1c) level with acceptable quality of life. Lessons: Laparoscopic total pancreatectomy is feasible and safe in selected patients and pylorus and spleen preserving technique should be considered. Further prospective randomized studies are needed to obtain a comprehensive understanding the role of laparoscopic technique in total pancreatectomy. PMID:28099344

Knowledge of preanalytic conditions that biospecimens are subjected to is critically important because novel surgical procedures, tissue sampling, handling, and storage might affect biomarker expression or invalidate tissue samples as analytes for some technologies. We investigated differences in RNA quality, gene expression by quantitative real-time PCR, and immunoreactive protein expression of selected prostate cancer biomarkers between tissues from retropubic radical prostatectomy (RRP) and robot-assisted laparoscopic prostatectomy (RALP). Sections of tissue microarray of 23 RALP and 22 RRP samples were stained with antibodies to androgen receptor (AR) and prostate-specific antigen (PSA) as intersite controls, and 14 other candidate biomarkers of research interest to three laboratories within the Australian Prostate Cancer BioResource tissue banking network. Quantitative real-time PCR was done for AR, PSA (KLK3), KLK2, KLK4, and HIF1A on RNA extracted from five RALP and five RRP frozen tissue cores. No histologic differences were observed between RALP and RRP tissue. Biomarker staining grouped these samples into those with increased (PSA, CK8/18, CKHMW, KLK4), decreased (KLK2, KLK14), or no change in expression (AR, ghrelin, Ki67, PCNA, VEGF-C, PAR2, YB1, p63, versican, and chondroitin 0-sulfate) in RALP compared with RRP tissue. No difference in RNA quality or gene expression was detected between RALP and RRP tissue. Changes in biomarker expression between RALP and RRP tissue exist at the immunoreactive protein level, but the etiology is unclear. Future studies should account for changes in biomarker expression when using RALP tissues, and mixed cohorts of RALP and RRP tissue should be avoided.

Full Text Available Objective: To evaluate the effects of bladder neck reconstruction techniques on early continence after laparoscopic radical prostatectomy (LRP. Materials and methods: This non-randomized retrospective study analyzed prospectively collected data concerning LRP. In total, 3107 patients underwent LRP between March 1999 and December 2016. Exclusion criteria were preoperative urinary incontinence, previous history of external beam radiotherapy, co-morbities which may affect urinary continence such as diabetes mellitus and/or neurogenic disorders, irregular followup, and follow-up shorter than 24 months. All patients were divided into one of three groups, posterior reconstruction being performed in Group 1 (n = 112, anterior reconstruction in Group 2 (n = 762, and bladder neck sparing (BNS in Group 3 (n = 987. Demographic and pre-, peri-, and postoperative data were collected. Multivariate analyses were performed to determine factors affecting early continence after LRP. Results: 1861 patients were enrolled in the study. The mean follow-up period was 48.12 ± 29.8 months, and subjects’ mean age was 63.6 ± 6.2 years. There was no significant difference among the groups in terms of demographic or preoperative data. Postoperative data, including oncological outcomes, were similar among the groups. The level of early continence was higher in Group 3 than in the other groups (p < 0.001. Multivariate analyses identified BNS and age as parameters significantly affecting early continence levels after LRP (p < 0.001 and p < 0.001, respectively. Bladder neck reconstruction provided less earlier continence than BNS.

Patients with liver cirrhosis represent a high risk group for colorectal surgery. The safety and effectiveness of laparoscopy in colorectal surgery for cirrhotic patients is not clear. The aim of this study was to compare the outcomes of laparoscopic colorectal surgery with those of open procedure for colorectal cancer in patients with liver cirrhosis. A total of 62 patients with cirrhosis who underwent radical resections for colorectal cancer from 2005 to 2014 were identified retrospectively from a prospective database according to the technique adopted (laparoscopic or open). Short- and long-term outcomes were compared between the two groups. Comparison of laparoscopic group and open group revealed no significant differences at baseline. In the laparoscopic group, the laparoscopic surgery was associated with reduced estimated blood loss (136 vs. 266 ml, p = 0.015), faster first flatus (3 vs. 4 days, p = 0.002) and shorter days to first oral intake (4 vs. 5 days, p = 0.033), but similar operative times (p = 0.856), number of retrieved lymph nodes (p = 0.400) or postoperative hospital stays (p = 0.170). Despite the similar incidence of overall complications between the two groups (50.0% vs. 68.8%, p = 0.133), we observed lower morbidities in laparoscopic group in terms of the rate of Grade II complication (20.0% vs. 50.0%, p = 0.014). Long-term of overall and Disease-free survival rates did not differ between the two groups. Laparoscopic colorectal surgery appears to be a safe and less invasive alternative to open surgery in some elective cirrhotic patients in terms of less blood loss or early recovery and does not result in additional harm in terms of the postoperative complications or long-term oncological outcomes.

Muscle-invasive bladder cancer (MIBC) is considered one of the most lethal malignancies with high metastatic potential. Usually, metastatic bladder cancer carries worse prognosis with a median survival rate of approximately 6 months, which can be prolonged for up to 14 months with palliative systemic chemotherapy. We present the case of a 61-year-old male patient diagnosed with localized MIBC 10 years ago. He underwent nerve-sparing radical cystectomy with ileal neobladder, but developed pulmonary metastatic disease 7 months postoperatively. Six cycles of gemcitabine/cisplatin combination chemotherapy with an addition of gefitinib as daily oral medication were administered within a randomized phase II clinical trial; this resulted in complete remission of the pulmonary metastases. Until now, the patient is still on gefitinib daily without any side effects. Although, the addition of gefitinib to standard systemic chemotherapy has not been shown to improve the survival in metastatic urothelial cancer, this case represents a very pleasant albeit uncommon long-term outcome. © 2016 S.

2017-01-01

Since early 1990’s, when it was inaugurally introduced, laparoscopic splenectomy has been performed with excellent results in terms of intraoperative and postoperative complications. Nowadays laparoscopic splenectomy is the approach of choice for both benign and malignant diseases of the spleen. However some contraindications still apply. The evolution of the technology has allowed though, cases which were considered to be absolute contraindications for performing a minimal invasive procedure to be treated with modified laparoscopic approaches. Moreover, the introduction of advanced laparoscopic tools for ligation resulted in less intraoperative complications. Today, laparoscopic splenectomy is considered safe, with better outcomes in comparison to open splenectomy, and the increased experience of surgeons allows operative times comparable to those of an open splenectomy. In this review we discuss the indications and the contraindications of laparoscopic splenectomy. Moreover we analyze the standard and modified surgical approaches, and we evaluate the short-term and long-term outcomes. PMID:28979707

This prospective study describes a simple method of combining laparoscopic ovariectomy and laparoscopic-assisted prophylactic gastropexy and determines the duration of surgery, complications, and long-term outcome including prevention of gastric dilatation-volvulus (GDV). Laparoscopic ovariectomy and laparoscopic-assisted gastropexy were performed on 26 sexually intact female dogs susceptible to GDV. The mean surgery time was 60.8 ± 12.4 min. No GDV episode was seen during the study period (mean follow-up: 5.2 ± 1.4 y). All dogs had an intact gastropexy attachment assessed by ultrasonography at 1 y. Post-operative complications were minor and owners were satisfied with the procedure. Combined laparoscopic ovariectomy and laparoscopic- assisted gastropexy appears to be a successful and low morbidity alternative procedure to both ovariectomy/ovariohysterectomy and gastropexy via open ventral-midline laparotomy.

The presence of postoperative bile leak is the major outcome measure for the assessment of operative success in partial cystectomy for hydatid liver disease. However, the optimal operative strategy to reduce the postoperative bile leak rate is yet to be defined. Medical records of patients who underwent partial cystectomy for hydatid liver disease between January 2013 and January 2015 were reviewed in this retrospective analysis. All patients were managed with a specific operative protocol. The primary outcome measure was the rate of persistent postoperative bile leak. The secondary outcome measures were the morbidity and mortality rate, and the length of hospital stay. Twenty-eight patients were included in the study. Only one patient (3.6 %) developed persistent postoperative bile leak. The overall morbidity and mortality rate was 17.8 and 0 %, respectively. The median length of hospital stay was 5 days. Aggressive preventative surgical measures have led to low persistent bile leak rates with low morbidity and mortality.

Laparoscopic simulation for all: two affordable, upgradable, and easy-to-build laparoscopic trainers.

2013-01-01

Laparoscopic surgery has established itself as the approach of choice for a multitude of operations in general, urological, and gynecological surgery. A number of factors make performing laparoscopic surgery technically demanding, and as such it is crucial that surgical trainees hone their skills safely on trainers before operating on patients. These can be highly expensive. Here, we describe a novel and upgradable approach to constructing an affordable laparoscopic trainer. A pattern was produced to build an upgradable laparoscopic trainer for less than $100. The basic model was constructed from an opaque plastic crate with plywood base, 2 trocars, and 2 pairs of disposable laparoscopic instruments. A laptop, a light emitting diode (LED), and a fixed webcam were utilized to visualize the box interior. An enhanced version was also created, as an optional upgrade to the basic model, featuring a neoprene-trocar interface and a simulated mobile laparoscope. The described setup allowed trainees to gain familiarity with laparoscopic techniques, beginning with simple manipulation and then progressing through to more relevant procedures. Novices began by moving easy-to-grasp objects between containers and then attempting more challenging manipulations such as stacking sugar cubes, excising simulated lesions, threading circular mints onto cotton, and ligating fastened drinking straws. These techniques have introduced the necessity of careful instrument placement and have increased trainees' dexterity with laparoscopy. Here, we have outlined an upgradable and affordable alternative laparoscopic trainer that has given many trainees crucial experience with laparoscopic techniques, allowing them to safely improve their manual skill and confidence.

Full Text Available Primary signet-ring cell carcinoma is a variant of adenocarcinoma which is extremely rare, associated with poor prognosis and generally found to be resistant to chemotherapy and radiotherapy. We report a case of primary signet-ring cell carcinoma of the bladder which was successfully treated with partial cystectomy. A 71-year-old female with a history of type 2 diabetes, hypertension, and ischaemic heart disease presented with painless haematuria for 2 months’ duration. The abdominal ultrasonography showed a localised polypoidal vesical growth arising from the bladder dome. Cystoscopy revealed an exophytic solid tumour in the anterior fundal wall. A deep transurethral resection of bladder tumour was done and histology revealed an adenocarcinoma composed of mucinous and signet-ring cell components. Later, considering the patient’s age and the poor general condition, a partial cystectomy was done. Follow-up cystoscopy and ultrasonography were done at 12 months and there was no evidence of tumour recurrence and the patient is currently symptom-free. Partial cystectomy may be considered in patients with localised tumour without evidence of metastasis and poor general condition. Regular cystoscopies and ultrasound imaging are necessary for follow-up and early identification of recurrences.

[Sacrocolpopexy - pro laparoscopic].

Innovative techniques have a really magical attraction for physicians as well as for patients. The number of robotic-assisted procedures worldwide has almost tripled from 80,000 procedures in the year 2007 to 205,000 procedures in 2010. In the same time the total number of Da Vinci surgery systems sold climbed from 800 to 1,400. Advantages, such as three-dimensional visualization, a tremor-filter, an excellent instrument handling with 6 degrees of freedom and better ergonomics, together with aggressive marketing led to a veritable flood of new Da Vinci acquisitions in the whole world. Many just took the opportunity to introduce a new instrument to save a long learning curve and start immediately in the surgical master class.If Da Vinci sacrocolpopexy is compared with the conventional laparoscopic approach, robotic-assisted sacrocolpopexy shows a significantly longer duration of the procedure, a higher need for postoperative analgesics, much higher costs and an identical functional outcome without any advantage over the conventional laparoscopic approach. Although the use of robotic-assisted systems shows a significantly lower learning curve for laparoscopic beginners, it only shows minimal advantages for the experienced laparoscopic surgeon. Therefore it remains uncertain whether robotic-assisted surgery shows a significant advantage compared to the conventional laparoscopic surgery, especially with small reconstructive laparoscopic procedures such as sacrocolpopexy.

A standard procedure for single-port laparoscopic adrenal surgery has not been established. We retrospectively investigated intraoperative and postoperative outcomes after laparoscopic adrenalectomy through mono port (LAMP) and conventional laparoscopic adrenalectomy to assess the feasibility of LAMP. Between March 2008 and December 2009, 22 patients underwent adrenalectomy at the Department of Surgery, Kangbuk Samsung Hospital. Twelve patients underwent conventional laparoscopic adrenalectomy and 10 patients underwent LAMP. The same surgeon performed all the surgeries. The 2 procedures were compared in terms of tumor size, operating time, time to resumption of a soft diet, length of hospital day, and postoperative complications. The 2 groups were similar in terms of tumor size (30.08 vs. 32.50 mm, P=0.796), mean operating time (112.9 vs. 127 min, P=0.316), time to resumption of a soft diet (1.25 vs. 1.30 d, P=0.805), and length of hospital day (4.08 vs. 4.50 d, P=0.447). Despite 1 patient in the LAMP group experiencing ipsilateral pleural effusion as a postoperative complication, this parameter was similar for the 2 groups (P=0.195). Perioperative mortality, blood transfusion, and conversion to open surgery did not occur. Perioperative outcomes for LAMP were similar to those for conventional laparoscopic adrenalectomy. LAMP appears to be a feasible option for adrenalectomy.

Selective bladder preservation with curative intent for muscle-invasive bladder cancer. A contemporary review

Radical cystectomy plus urinary diversion, the reference standard treatment for muscle-invasive bladder cancer, associates with high complication rates and compromises quality of life as a result of long-term effects on urinary, gastrointestinal and sexual function, and changes in body image. As a society ages, the number of elderly patients unfit for radical cystectomy as a result of comorbidity will increase, and thus the demand for bladder-sparing approaches for muscle-invasive bladder cancer will also inevitably increase. Trimodality bladder-sparing approaches consisting of transurethral resection, chemotherapy and radiotherapy (Σ55-65 Gy) yield overall survival rates comparable with those of radical cystectomy series (50-70% at 5 years), while preserving the native bladder in 40-60% of muscle-invasive bladder cancer patients, contributing to an improvement in quality of life for such patients. Limitations of the trimodality therapy include muscle-invasive bladder cancer recurrence in the preserved bladder, which most often arises in the original muscle-invasive bladder cancer site; potential lack of curative intervention for regional lymph nodes; and increased morbidity in the event of salvage radical cystectomy for remaining or recurrent disease as a result of high-dose pelvic irradiation. Consolidative partial cystectomy with pelvic lymph node dissection followed by induction chemoradiotherapy at lower dose (exempli gratia (e.g.) 40 Gy) is a rational strategy for overcoming such limitations by strengthening locoregional control and reducing radiation dosage. Molecular profiling of the tumor and functional imaging might play important roles in optimal patient selection for bladder preservation. Refinement of radiation techniques, intensified concurrent or adjuvant chemotherapy, and novel sensitizers, including molecular targeting agent, are also expected to improve outcomes and consequently provide more muscle-invasive bladder cancer patients with favorable

The challenges in laparoscopic suturing include need to expertise to suture. Laparoscopic needle holder is a" key" instrument to accomplish this arduous task. The objective of this new invention was to develop a laparoscopic needle holder which would be adapted to avoid any wobble (with a shaft diameter same as a 5mm port), ensure accurate and dexterous suturing not just in adult patients but pediatric patients alike (with a short shaft diameter) and finally ensure seamless throw of knots with a narrow tip configuration. We did an initial evaluation to evaluate the validity of the prototype needle holder and its impact on laparoscopic suturing skills by experienced laparoscopic surgeons and novice laparoscopic Surgeons. Both the groups of surgeons performed two tasks. The first task was to grasp the needle and position it in an angle deemed ideal for suturing. The second task was to pass suture through two fixed points and make a single square knot. At the end of the tasks each participant was asked to complete a 5- point Likert's scale questionnaire (8 items; 4 items of handling and 4 items of suturing) rating each needle holder. In expert group, the mean time to complete task 1 was shorter with prototype 3/5 laparoscopic needle holder (11.8 sec Vs 20.8 sec). The mean time to complete task 2 was also shorter with prototype 3/5 laparoscopic needle holder (103.2 sec Vs 153.2 sec). In novice group, mean time to complete both the task was shorter with prototype 3/5 laparoscopic needle holder. The expert laparoscopic surgeons as well as novice laparoscopic surgeons performed laparoscopic suturing faster and with more ease while using the prototype 3/5 laparoscopic needle holder.

Full Text Available A vesicovaginal fistula is one of the complications that a gynaecologist is bound to face after oncological operations, especially in postmenopausal women. Over the years there have been introduced many techniques of surgical treatment of this entity, including transabdominal and transvaginal approaches.We present a case of a 46-year-old patient who suffered from urinary leakage via the vagina due to the presence of a vesicovaginal fistula that developed after radical abdominal hysterectomy and subsequent radiotherapy. The decision was made to repair it laparoscopically due to retracted, fibrous and scarred tissue in the vaginal apex that precluded a transvaginal approach. A small cystotomy followed by an excision of fistula borders was performed. After six-month follow-up no recurrence of the disease has been noted.We conclude that laparoscopy is an interesting alternative to traditional approaches that provides comparable results.

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

Paraovarian cysts are very uncommon in children To present a case of giant paraovarian cyst case in a child and its management using a modified laparoscopic-assisted technique A 13-year-old patient with a 15 day-history of intermittent abdominal pain, located in the left hemiabdomen and associated with progressive increase in abdominal volume. Diagnostic imaging was inconclusive, describing a giant cystic formation that filled up the abdomen, but without specifying its origin. Laboratory tests and tumor markers were within normal range. Video-assisted transumbilical cystectomy, a modified laparoscopic procedure with diagnostic and therapeutic intent, was performed with a successful outcome. The histological study reported giant paraovarian cyst. Cytology results were negative for tumor cells. The patient remained asymptomatic during the postoperative follow-up. The video-assisted transumbilical cystectomy is a safe procedure and an excellent diagnostic and therapeutic alternative for the treatment of giant paraovarian cysts. Copyright © 2015.

Filshie, G M

1989-09-01

An overview of laparoscopic sterilization techniques from a historical and practical viewpoint includes instrumentation, operative techniques, mechanical occlusive devices, anesthesia, failure rates, morbidity and mortality. Laparoscope was first reported in 1893, but was developed simultaneously in France, Great Britain, Canada and the US in the 1960s. There are smaller laparoscopes for double-puncture procedures, and larger, single-puncture laparoscopes. To use a ring or clip, a much larger operating channel, up to 8 mm is needed. Insufflating gas may be CO2, which does not support combustion, but is more uncomfortable, NO2, which is also an anesthetic, and room air often used in developing countries. Unipolar electrocautery is now rarely used, in fact most third party payers do not allow it. Bipolar cautery, thermal coagulation and laser photocoagulation are safer methods. Falope rings, Hulka-Clemens, Filshie, Bleier, Weck and Tupla clips are described and illustrated. General anesthesia, usually a short acting agent with a muscle relaxant, causes 33% of the mortality of laparoscope, often due to cardiac arrest and arrhythmias, preventable with atropine. Local anesthesia is safer and cheaper and often used in developing countries. Failure rates of the various laparoscopic tubal sterilization methods are reviewed: most result from fistula formation. Mortality and morbidity can be caused by bowel damage, injury or infection, pre- existing pelvic infection, hemorrhage, gas embolism (avoidable by the saline drip test), and other rare events.

Laparoscopic surgery has become the treatment of choice for the management of perforated peptic ulcer. The advantages of laparoscopic repair for perforated peptic ulcer include less pain, a short hospital stay, and an early return to normal activity. Although the operation time of laparoscopic surgery is significantly longer than that of open surgery, laparoscopic technique is safe, feasible, and with morbidity and mortality comparable to that of the conventional open technique. To benefit from the advantages offered by minimally invasive laparoscopic technique, further study will need to determine whether laparoscopic surgery is safe in patients with generalized peritonitis or sepsis.

Perioperative transfusions have been recently associated to poor outcomes as an indirect consequence of immune-hematological changes related to transfusion itself and blood type. We tested the role of blood transfusion on cancer-specific mortality (CSM) and overall mortality (OM), considering the effect of ABO system, Rh factor, and timing of transfusions. The study focused on 728 patients with bladder cancer treated with radical cystectomy at a single tertiary care referral center between January 1995 and August 2013 with complete ABO blood type information. Kaplan-Meier analysis was used to assess the effect of transfusions, stratified according to ABO type and Rh factor, on CSM and OM. The same endpoints were tested in Cox regression models, after adjusting for all available confounders. A total of 341 (46.8%), 277 (38.0%), 83 (11.4%), and 27 (3.7%) patients had blood type O, A, B and AB, respectively. Overall, 630 (86.5%) and 98 (13.5%) patients were Rh-and Rh+, respectively. At a median follow-up time of 65 months, 225 (30.9%) and 282 (38.7%) patients recorded CSM and OM, respectively. At univariable analyses, ABO blood type and Rh status were not associated to either CSM or OM (all P>0.2). Similar results were observed when ABO blood type and Rh factor were tested in multivariable models (all P>0.3). Conversely, Charlson score, preoperative hemoglobin, number of nodes removed, pathological T stage, and number of positive nodes were associated to both CSM and OM (all Pblood units in the postoperative period (P>0.05) was associated with an increase of CSM and OM. Although ABO type or Rh factor or both were associated with several adverse outcomes in many cancers, we were not able to confirm this association in bladder cancer. Based on our results, the effect of transfusion on survival is independent by ABO type but is associated to the timing of blood supply administration. Copyright © 2016 Elsevier Inc.

Full Text Available Introduction. Laparoscopic radical nephroureterectomy (LNU is being increasingly performed at several centers across the world. We review oncologic outcomes after LNU procedure and the techniques for the management of distal ureter. Materials and Methods. A comprehensive review of the literature was performed on the oncological outcomes and management of distal ureter associated with LNU for upper tract transitional cell carcinoma (TCC. Results and Discussion. LNU for upper tract TCC is performed pure laparoscopically (LNU or hand-assisted (HALNU. The management of the distal ureter is still debated. LNU appears to have superior perioperative outcomes when compared to open surgery. Intermediate term oncologic outcomes after LNU are comparable to open nephroureterectomy (ONU. Conclusions. Excision of the distal ureter and bladder cuff during nephroureterectomy remains controversial. Intermediate term oncologic outcomes for LNU compare well with ONU. Initial long-term oncologic outcomes are encouraging. Prospective randomized comparison between LNU and open surgery is needed to define the role of these modalities in the current context.

To evaluate single-port assisted extracorporeal cystectomy for treatment of large ovarian cysts and to compare its surgical outcomes, complications, and cystic content spillage rates with those of conventional laparoscopy and laparotomy. Retrospective study (Canadian Task Force classification II-2). University teaching hospital. Twenty-five patients who underwent single-port assisted extracorporeal cystectomy (group 1), 33 patients who underwent conventional laparoscopy (group 2), and 25 patients who underwent laparotomy (group 3). Surgical outcomes, complications, and spillage rates in group 1 were compared with those in groups 2 and 3. Patients characteristics and tumor histologic findings were similar in the 3 groups. The mean (SD) largest diameter of ovarian cysts was 11.4 (4.2) cm in group 1, 9.7 (2.3) cm in group 2, and 12.0 (3.4) cm in group 3. Operative time in groups 1 and 2 was similar at 69.3 (26.3) minutes vs 73.1 (36.3) minutes (p = .66); however, operative time in group 1 was shorter than in group 3, at 69.3 (26.3) minutes vs 87.5 (26.6) minutes (p =.02). Blood loss in group 1 was significantly lower than in groups 2 and 3, at 16.0 (19.4) mL vs 36.1 (20.7) mL (p < .001) and 16.0 (19.4) mL vs 42.2 (39.7) mL (p = .005). The spillage rate in group 1 was profoundly lower than in group 2, at 8.0% vs 69.7% (p < .001). Single-port assisted extracorporeal cystectomy offers an alternative to conventional laparoscopy and laparotomy for management of large ovarian cysts, with comparable surgical outcomes. Furthermore, cyst content spillage rate in single-port assisted extracorporeal cystectomy was remarkably lower than that in conventional laparoscopy. Copyright © 2015. Published by Elsevier Inc.

Laparoscopic surgery is applied today worldwide to most digestive procedures. In some of them, such as cholecystectomy, Nissen’s fundoplication or obesity surgery, laparoscopy has become the standard in practice. In others, such as colon or gastric resection, the laparoscopic approach is frequently used and its usefulness is unquestionable. More complex procedures, such as esophageal, liver or pancreatic resections are, however, more infrequently performed, due to the high grade of skill necessary. As a result, there is less clinical evidence to support its implementation. In the recent years, robot-assisted laparoscopic surgery has been increasingly applied, again with little evidence for comparison with the conventional laparoscopic approach. This review will focus on the complex digestive procedures as well as those whose use in standard practice could be more controversial. Also novel robot-assisted procedures will be updated.

Schwannomas are usually benign tumors attached to peripheral nerves and are rarely found in the gastrointestinal tract. Schwannomas in the porta hepatis are extremely rare, with only 15 cases described in the literature to date. A 22-year-old female patient presented with colicky upper abdominal pain lasting 3 months. Magnetic resonance imaging of the abdominal cavity revealed a tumor in the porta hepatis. The patient was qualified for laparoscopy. The tumor was totally excised laparoscopically under guidance of laparoscopic ultrasound without intra- or postoperative complications. Postoperative histopathological examination confirmed the porta hepatic schwannoma. The patient recovered uneventfully with very good cosmetic results. In the follow-up period of 5 months we have not observed any abdominal or general health problems. The present case is the first report in the world of laparoscopic ultrasound guided laparoscopic excision of a porta hepatic schwannoma.

Minimally invasive radical pancreatectomy for left-sided pancreatic cancer: Current status and future perspectives

Kang, Chang Moo; Lee, Sung Hwan; Lee, Woo Jung

2014-01-01

Minimally invasive distal pancreatectomy with splenectomy has been regarded as a safe and effective treatment for benign and borderline malignant pancreatic lesions. However, its application for left-sided pancreatic cancer is still being debated. The clinical evidence for radical antegrade modular pancreatosplenectomy (RAMPS)-based minimally invasive approaches for left-sided pancreatic cancer was reviewed. Potential indications and surgical concepts for minimally invasive RAMPS were suggested. Despite the limited clinical evidence for minimally invasive distal pancreatectomy in left-sided pancreatic cancer, the currently available clinical evidence supports the use of laparoscopic distal pancreatectomy under oncologic principles in well-selected left sided pancreatic cancers. A pancreas-confined tumor with an intact fascia layer between the pancreas and left adrenal gland/kidney positioned more than 1 or 2 cm away from the celiac axis is thought to constitute a good condition for the use of margin-negative minimally invasive RAMPS. The use of minimally invasive (laparoscopic or robotic) anterior RAMPS is feasible and safe for margin-negative resection in well-selected left-sided pancreatic cancer. The oncologic feasibility of the procedure remains to be determined; however, the currently available interim results indicate that even oncologic outcomes will not be inferior to those of open radical distal pancreatosplenectomy.

The role of laparoscopic surgery in treatment of patients with diverticulitis is unclear. A retrospective comparison of laparoscopic with conventional surgery for patients with chronic diverticulitis was performed to assess morbidity, recovery from surgery, and cost. Records of patients undergoing elective resection for uncomplicated diverticulitis from 1992 to 1994 at a single institution were reviewed. Laparoscopic resection involved complete intracorporeal dissection, bowel division, and anastomosis with extracorporeal placement of an anvil. Sigmoid and left colon resections were performed laparoscopically in 25 patients and by open technique in 17 patients by two independent operating teams. No significant differences existed in age, gender, weight, comorbidities, or operations performed. In the laparoscopic group, three operations were converted to open laparotomy (12 percent) because of unclear anatomy. Major complications occurred in two patients who underwent laparoscopic resection, both requiring laparotomy, and in one patient in the conventional surgery group who underwent computed tomographic-guided drainage of an abscess. Patients who underwent laparoscopic resection tolerated a regular diet sooner than patients who underwent conventional surgery (3.2 +/- 0.9 vs. 5.7 +/- 1.1 days; P < 0.001) and were discharged from the hospital earlier (4.2 +/- 1.1 vs. 6.8 +/- 1.1 days; P < 0.001). Overall costs were higher in the laparoscopic group than the open surgery group ($10,230 +/- 49.1 vs. $7,068 +/- 37.1; P < 0.001) because of a significantly longer total operating room time (397 +/- 9.1 vs. 115 +/- 5.1 min; P < 0.001). Follow-up studies with a mean of one year revealed two port site infections in the laparoscopic group and one wound infection in the open group. Of patients undergoing conventional resection, one patient experienced a postoperative bowel obstruction that was managed nonoperatively, and, in one patient, an incarcerated incisional hernia

Defect filling of extensive cavities in the region of the jaw after cystectomies of large odontogenic cysts constitutes a particular problem as the restoration of the carrying capacity of the crest of the jaw is of decisive signifance for sufficient prosthetic surgery. The fibrin-spongiosa graft method was performed in all patients; both homologous and autologous cancellous tissue was used. In addition to X-ray examinations, for the first time nuclear medical examination methods were used for assessing the future site of the graft and checking the postoperative healing process. This method permitted not only detection of an osteomyelitis during pre-operative examinations, but in one case also a disturbance of the postoperative healing process was discovered. Therefore, the combined X-ray - isotope examination constitutes the method of choice as regards diagnosis, planning of treatment and control of the healing process. (Author)

Full Text Available Background. In laparoscopic surgery errors are unavoidable and require proper acknowledgment to reduce the risk of intraoperative and accurately assess the appropriate therapeutic approach. Fortunately, their frequency is low and cannot overshadow the benefits of laparoscopic surgery. Materials and Methods. We made an epidemiological investigation in General Surgery Department of Emergency Clinical Hospital "St. John" Bucharest, analyzing 20 years of experience in laparoscopic surgery, during 1994-2014. We wanted to identify evolution trends in complications of laparoscopic surgery, analyzing the dynamic of errors occurred in all patients with laparoscopic procedures. Results. We recorded 26847 laparoscopic interventions with a total of 427 intra-or postoperative complications that required 160 conversions and 267 reinterventions to resolve inconsistencies. The average frequency of occurrence of complications was 15.9‰ (15.9 of 1,000 cases. In the period under review it was a good momentum of laparoscopic procedures in our department. Number of minimally invasive interventions increased almost 10 times, from 266 cases operated laparoscopically in 1995 to 2638 cases in 2008. Annual growth of the number of laparoscopic procedures has surpassed the number of complications. Conclusions. Laborious work of laparoscopic surgery and a specialized centre with well-trained team of surgeons provide premises for a good performance even in the assimilation of new and difficult procedures.

Laparoscopic resection of transverse colon carcinoma is technically demanding and was excluded from most of the large trials of laparoscopic colectomy. The aim of this study was to assess the safety, feasibility, and outcome of laparoscopic resection of carcinoma of the transverse colon. A retrospective review was performed to identify patients who underwent laparoscopic resection of transverse colon carcinoma. These patients were compared to patients who had laparoscopic resection for right and sigmoid colon carcinoma. In addition, they were compared to a historical series of patients who underwent open resection for transverse colon cancer. A total of 22 patients underwent laparoscopic resection for transverse colon carcinoma. Sixty-eight patients operated for right colon cancer and 64 operated for sigmoid colon cancer served as comparison groups. Twenty-four patients were identified for the historical open group. Intraoperative complications occurred in 4.5% of patients with transverse colon cancer compared to 5.9% (P = 1.0) and 7.8% (P = 1.0) of patients with right and sigmoid colon cancer, respectively. The early postoperative complication rate was 45, 50 (P = 1.0), and 37.5% (P = 0.22) in the three groups, respectively. Conversion was required in 1 (5%) patient in the laparoscopic transverse colon group. The conversion rate and late complications were not significantly different in the three groups. There was no significant difference in the number of lymph nodes harvested in the laparoscopic and open groups. Operative time was significantly longer in the laparoscopic transverse colectomy group when compared to all other groups (P = 0.001, 0.008, and transverse colectomy, respectively). The results of laparoscopic colon resection for transverse colon carcinoma are comparable to the results of laparoscopic resection of right or sigmoid colon cancer and open resection of transverse colon carcinoma. These results suggest that laparoscopic resection of transverse

Purpose/Objective: To assess the success of selective organ preservation or radical cystectomy in a large group of patients with muscle-invasive bladder cancer treated with induction by combined transurethral resection (TURBT), systemic chemotherapy and radiation therapy. Materials and Methods: 106 patients (median age 68 years) were treated with induction by maximal TURBT and 2 cycles of chemotherapy (methotrexate, cisplatin, vinblastine - MCV) followed by 39.6 Gy irradiation in 1.8 Gy fractions with concomitant cisplatin. Tumor response was then evaluated by cystoscopy, rebiopsy, and urine cytology. Complete responders were consolidated with radiation to 64.8 Gy and further cisplatin. Any subsequent isolated invasive local relapse was managed by cystectomy. Patients with any less than a complete response (CR) were recommended cystectomy. Median follow-up was 4.4 years. Kaplan-Meier analysis was used to assess outcome. Results: 74 CR patients (70%) and 7 non-cystectomy candidates with less than a CR (7%) received consolidation chemotherapy and radiation. 13 incomplete responders (12%) underwent immediate cystectomy. 6 patients underwent cystectomy because they could not tolerate induction chemo-radiation. 1 complete response patient underwent radical cystectomy. 83 patients completed their planned therapy but 5 died of treatment related toxicity during induction chemotherapy. Five year actuarial overall survival and disease-specific survival were 52% and 60% respectively. For T2 patients, actuarial overall survival was 63%, and for T3-4, 45%. Five year survival with an intact functioning bladder was 43%. Five year freedom from distant metastases was 66%. Of those who had a CR after TURBT and MCV, the risk of a subsequent invasive bladder relapse was 18% at 5 years. Of those who had a CR after the completion of induction chemotherapy and 39.6 Gy, this risk was 21%. 18 patients (17%) have experienced a non-invasive bladder relapse requiring further TUR and

Purpose/Objective: To assess the success of selective organ preservation or radical cystectomy in a large group of patients with muscle-invasive bladder cancer treated with induction by combined transurethral resection (TURBT), systemic chemotherapy and radiation therapy. Materials and Methods: 106 patients (median age 68 years) were treated with induction by maximal TURBT and 2 cycles of chemotherapy (methotrexate, cisplatin, vinblastine - MCV) followed by 39.6 Gy irradiation in 1.8 Gy fractions with concomitant cisplatin. Tumor response was then evaluated by cystoscopy, rebiopsy, and urine cytology. Complete responders were consolidated with radiation to 64.8 Gy and further cisplatin. Any subsequent isolated invasive local relapse was managed by cystectomy. Patients with any less than a complete response (CR) were recommended cystectomy. Median follow-up was 4.4 years. Kaplan-Meier analysis was used to assess outcome. Results: 74 CR patients (70%) and 7 non-cystectomy candidates with less than a CR (7%) received consolidation chemotherapy and radiation. 13 incomplete responders (12%) underwent immediate cystectomy. 6 patients underwent cystectomy because they could not tolerate induction chemo-radiation. 1 complete response patient underwent radical cystectomy. 83 patients completed their planned therapy but 5 died of treatment related toxicity during induction chemotherapy. Five year actuarial overall survival and disease-specific survival were 52% and 60% respectively. For T2 patients, actuarial overall survival was 63%, and for T3-4, 45%. Five year survival with an intact functioning bladder was 43%. Five year freedom from distant metastases was 66%. Of those who had a CR after TURBT and MCV, the risk of a subsequent invasive bladder relapse was 18% at 5 years. Of those who had a CR after the completion of induction chemotherapy and 39.6 Gy, this risk was 21%. 18 patients (17%) have experienced a non-invasive bladder relapse requiring further TUR and

In this case report, we discuss single-incision laparoscopic cecectomy for low-grade appendiceal neoplasm after laparoscopic anterior resection for rectal cancer. The optimal surgical therapy for low-grade appendiceal neoplasm is controversial; currently, the options include appendectomy, cecectomy, right hemicolectomy, and open or laparoscopic surgery. Due to the risk of pseudomyxoma peritonei, complete resection without rupture is necessary. We have encountered 5 cases of low-grade appendiceal neoplasm and all 5 patients had no lymph node metastasis. We chose the appendectomy or cecectomy without lymph node dissection if preoperative imaging studies did not suspect malignancy. In the present case, we performed cecectomy without lymph node dissection by single-incision laparoscopic surgery (SILS), which is reported to be a reduced port surgery associated with decreased invasiveness and patient stress compared with conventional laparoscopic surgery. We are confident that SILS is a feasible alternative to traditional surgical procedures for borderline tumors, such as low-grade appendiceal neoplasms. PMID:24868331

To compare three ports laparoscopic cholecystectomy and four ports laparoscopic cholecystectomy in terms of complications, time taken to complete the procedure, hospital stay and cost effectiveness in local perspective. Methodology: This randomized control trial included 60 patients who underwent elective laparoscopic cholecystectomy at Department of Surgery, Pakistan Institute of Medical Sciences, Islamabad, Pakistan from January 2013 to June 2013. These patients were randomized on computer generated table of random numbers into group A and Group B. In Group A patients four ports were passed to perform laparoscopic cholecystectomy and in Group B patients three ports were passed to perform the procedure. Results: The mean age in both groups was 44 years (range 18-72). Three ports laparoscopic cholecystectomy (43 min) took less time to complete than four ports laparoscopic cholecystectomy (51 min). Patients in three ports laparoscopic cholecystectomy experienced less pain as compared to four ports group. The total additional analgesia requirement in 24 hours calculated in milligrams was less in three port laparoscopic cholecystectomy group as compared four port laparoscopic cholecystectomy group. The mean hospital stay in three port laparoscopic cholecystectomy group is 25 hours while the mean hospital stay in the four port laparoscopic cholecystectomy group is 28 hours. Conclusion: Three ports laparoscopic cholecystectomy is safe and effective procedure and it did not compromise the patient safety. (author)

2001-09-01

The totally laparoscopic approach to partial gastrectomy had not been compared previously with results of the open technique. This study compares the results of a series of laparoscopic cases with matched open cases. A retrospective case-matched study was performed in 36 patients (18 laparoscopic surgeries, 18 open surgeries). Each laparoscopic case was matched for patient age and indication for surgery. The intraoperative and postoperative details of the two groups were compared. Laparoscopic surgery resulted in less blood loss, although operative time was increased. Nasogastric tubes were less likely to be used after laparoscopic surgery, and patients in the laparoscopic group had an earlier return to normal bowel function than those in the open group. Length of hospital stay was 2 days shorter in the laparoscopic group. The totally laparoscopic approach to partial gastrectomy is an excellent alternative to the more traditional open approach. It results in a more rapid return of intestinal function and a shorter hospital stay.

2013-01-01

This work aimed to study the safety and efficacy of preoperative intestinal stent decompression combined with laparoscopic surgery to treat left-sided colorectal cancer with obstruction (LCCO). Retrospective analysis was conducted on data obtained from 21 LCCO patients admitted to The First Affiliated Hospital of Zhejiang Chinese Medicine University during March 2008 and December 2011. To remove the intestinal obstruction, preoperative intestinal stent placement under colonoscopic guidance was performed. Approximately 7 to 10 days after the operation, laparoscopic radical surgery of colorectal cancer was conducted. Among the 21 cases studied, laparoscopic surgery was successful in 20 patients. Emergent laparotomy was conducted in one patient because of tumor invasion in the ureter. The duration of the operation ranged from 180 to 320 min, and the average time was 220 min. The recovery time for bowel function ranged from 2 to 5 days with an average time of 3 days. Postoperative infection of the incision occurred in one case. No anastomotic leakage was observed in any of the cases. Preoperative intestinal stent decompression, combined with primary stage laparoscopic surgery, is a safe and effective method for the treatment of LCCO

Although the many advantages of laparoscopic surgery have made it an established technique, training in laparoscopic surgery posed problems not encountered in conventional surgical training. Virtual reality simulators open up new perspectives for training in laparoscopic surgery. Under realistic conditions in real time, trainees can tailor their sessions with the VR simulator to suit their needs and goals, and can repeat exercises as often as they wish. VR simulators reduce the number of experimental animals needed for training purposes and are suited to the pursuit of research in laparoscopic surgery.

A small number of patients fail fundoplication and require reoperation. Laparoscopic techniques have been applied to reoperative fundoplications. We reviewed our experience with reoperative laparoscopic fundoplication. Reoperative laparoscopic fundoplication was undertaken in 28 patients, 19 F and 9 M, of mean age 56 years +/- 12. Previous antireflux procedures included 19 open and 12 laparoscopic antireflux operations. Symptoms were heartburn (90%), dysphagia (35%), and atypical symptoms (30%%). The mean interval from antireflux procedure to revision was 13 months +/- 4.2. The mean DeMeester score was 78+/-32 (normal 14.7). Eighteen patients (64%) had hiatal breakdown, 17 (60%) had wrap failure, 2 (7%) had slipped Nissen, 3 (11%) had paraesophageal hernias, and 1 (3%) had an excessively tight wrap. Twenty-five revisions were completed laparoscopically, while 3 patients required conversion to the open technique. Complications occurred in 9 of 17 (53%) patients failing previous open fundoplications and in 4 of 12 patients (33%) failing previous laparoscopic fundoplications and included 15 gastrotomies and 1 esophagotomy, all repaired laparoscopically, 3 postoperative gastric leaks, and 4 pneumothoraces requiring tube thoracostomy. No deaths occurred. Median length of stay was 5 days (range 2-90 days). At a mean follow-up of 20 months +/- 17, 2 patients (7%) have failed revision of their fundoplications, with the rest of the patients being essentially asymptomatic (93%). The results achieved with reoperative laparoscopic fundoplication are similar to those of primary laparoscopic fundoplications. Laparoscopic reoperations, particularly of primary open fundoplication, can be technically challenging and fraught with complications. Copyright 2001 Academic Press.

Full Text Available Laparoscopic surgery provides patients with less painful surgery but is more demanding for the surgeon. The increased technological complexity and sometimes poorly adapted equipment have led to increased complaints of surgeon fatigue and discomfort during laparoscopic surgery. Ergonomic integration and suitable laparoscopic operating room environment are essential to improve efficiency, safety, and comfort for the operating team. Understanding ergonomics can not only make life of surgeon comfortable in the operating room but also reduce physical strains on surgeon.

Full Text Available This study aimed to evaluated laparoscopic ureterocalicostomy as treatment of experimental ureteropelvic junction (UPJ obstruction in pigs. Ten male Large White pigs weighting approximately 28.4 (±1.43 kg were used in the current study. The UPJ obstruction was created laparoscopically by double-clipping of the left ureter. After 14 days the animals underwent laparoscopic ureterocalicostomy f The animals were sacrificed for subsequent retrograde pyelography in order to assess the anastomotic patency on the 28th day. The laparoscopic procedure for experimental obstruction of UPJ was successfully performed in all animals, as well as the laparoscopic ureterocalicostomy. There was intestinal iatrogenic injury in one animal. Satisfactory UPJ patency was noted in 75% of the animals. There was no stenosis of the proximal anastomosis between the ureter and the lower pole of the kidney in 37.5%, mild stenosis in 37.5% and severe stenosis in 25% of the animals. The laparoscopic approach for reestablishment he urinary flow by ureterocalicostomy was feasible in the porcine model. The ascending pyelography revealed satisfactory results of the laparoscopic ureterocalicostomy

Robotic surgery overcomes some limitations of laparoscopic surgery for prostate, rectal and uterine cancer. In this study we analyze the feasibility of robotic radical hysterectomy with pelvic lymphadenectomy in gynecological cancers in a developping program of robotic surgery. This prospective study started the 1st of March 2008. Since then, 250 cases of robotic surgery were performed out of which 29 cases addressed gynecological conditions. We selected all radical interventions summing up to 19 cases. Our final group consisted of 19 patients, a gedbetween 30 and 78 years old, with an average age of 53.22 years (+/- 10.03). Twelve patients were diagnosed with cervical cancer, the rest of them with endometrial cancer. Mean operative time was 180 +/- 23.45 min. Oral intake were started the next day after the operation and the patients were discharged 3.5 (+/- 1.2) days postoperatively. There were 3 urinary complications in patients with tumors adherent to the urinary bladder. We believe that robotic radical hysterectomy with pelvic lymphadenectomy in gynecological cancers is a rapid, feasible, and secure method that should be used whenever available. However further prospective studies and late follow-up results are needed in order to fully assess the value of this new technology.

Minimal Invasive Urologic Surgery and Postoperative Ileus

Directory of Open Access Journals (Sweden)

Fouad Aoun

2015-07-01

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.

Full Text Available Robotic surgery is an option to laparoscopy that may offer some benefits including the possibility of performing surgery when the surgeon is geographically away from the patient and faster tireless repetitive movements with greater precision. At present, robot-assisted surgery has been done routinely in several institutions around the world, however, to the best of our knowledge, it is the first time such procedure is performed in our academic environment and herein is reported the first telerobotic-assisted laparoscopic cystectomy performed in a domestic pig at our institution using the Zeus®robotic system (Computer Motion, EUA. The procedure was performed using two different operating rooms geographically apart from each other. The assistant was in an operating room that was set with the operating table and the pig as well as with the Zeus® robotic arms. In the other operating room, the surgeon was seated in the control console with a three-dimensional imaging five meters away from the operating table connected with electric cables. The assistant surgeon established the pneumoperitoneum and five trocars were placed in a fan configuration. The surgeon started performing the surgery using three out of the five ports taking control of the laparoscope (voice control and manual control of laparoscopic instruments connected to the robotic arms using the joysticks. The other two ports were used by the assistant for traction and clips placement that was also necessary for exchanging the many laparoscopic instruments connected to the robot. The laparoscopic total cystectomy was successfully performed in 25 minutes with no complications. The truly benefits as well as the cost-effectiveness of the robotic surgery in our environment is yet to be determined after experience acquisition with telerobotic before start performing such procedures routinely in humans. The present report shows the technical feasibility of telerobotic surgery in a developing

2007-01-01

For patients with invasive bladder cancer the usual recommended treatment is radical cystectomy, although transurethral resection of the tumor, systemic chemotherapy, and radiotherapy are each effective in some patients. This retrospective study evaluated the experience of the Clinical Oncology Department, Tanta University Hospital with combined modality treatment and selective bladder preservation in patients with muscle-invading bladder cancer with assessment of its safety, tolerance, and efficacy to determine whether these treatments in combination might be as effective as radical cystectomy and thus might allow the bladder to be preserved and the cancer cured and to identify factors that may predict treatment response, risk of relapse and survival. Patients and Methods: Between January 2000 and January 2006, 55 consecutive patients with muscle invading bladder cancer (stages T2 through T4, NX M0) were treated with as complete transurethral surgery as possible, followed by induction combination chemotherapy, and irradiation with 4500 cGy with concurrent cisplatin administration. Urologic evaluation by cystoscopy, cytology, and re biopsy 2-3 weeks later of the tumor response directed further therapy: either radical cystectomy in the patients who had incomplete responses, or additional chemotherapy with the same drugs and doses and radiotherapy up to 6480 cGy in the patients who had complete responses. The median follow-up was 48 months. Results: In 37 patients (67.3%) the bladder was free of invasive tumor and functioning well, even though in 13(23.6%) a superficial tumor recurred and required further transurethral surgery and intravesical drug therapy. Of the 18 (32.7%) patients who still had detectable tumor after initial treatment, all of them underwent radical cystectomy. None of the patients had required a cystectomy for radiation toxicity. Of the 37 (67.3%) patients who had complete responses with no tumor detectable on urine cytology or re biopsy after

Hassan, Mohamed E; Al Ali, Khalid

2014-01-01

Laparoscopic splenectomy for massive splenomegaly is still a controversial procedure as compared with open splenectomy. We aimed to compare the feasibility of laparoscopic splenectomy versus open splenectomy for massive splenomegaly from different surgical aspects in children. The data of children aged splenectomy for hematologic disorders were retrospectively reviewed in 2 pediatric surgery centers from June 2004 until July 2012. The study included 32 patients, 12 who underwent laparoscopic splenectomy versus 20 who underwent open splenectomy. The mean ages were 8.5 years and 8 years in the laparoscopic splenectomy group and open splenectomy group, respectively. The mean operative time was 180 minutes for laparoscopic splenectomy and 120 minutes for open splenectomy. The conversion rate was 8%. The mean amount of intraoperative blood loss was 60 mL in the laparoscopic splenectomy group versus 110 mL in the open splenectomy group. Postoperative atelectasis developed in 2 cases in the open splenectomy group (10%) and 1 case in the laparoscopic splenectomy group (8%). Oral feeding postoperatively resumed at a mean of 7.5 hours in the laparoscopic splenectomy group versus 30 hours in the open splenectomy group. The mean hospital stay was 36 hours in the laparoscopic splenectomy group versus 96 hours in the open splenectomy group. Postoperative pain was less in the laparoscopic splenectomy group. Laparoscopic splenectomy for massive splenomegaly in children is safe and feasible. Although the operative time was significantly greater in the laparoscopic splenectomy group, laparoscopic splenectomy was associated with statistically significantly less pain, less blood loss, better recovery, and shorter hospital stay. Laparoscopic splenectomy for pediatric hematologic disorders should be the gold-standard approach regardless of the size of the spleen.

The objective of this study was to present the initial operative experience of solo surgeon single-port laparoscopic surgery (SPLS) in the laparoscopic treatment of benign gynecologic diseases and to investigate its feasibility and surgical outcomes. Using a novel homemade laparoscope-anchored instrument system that consisted of a laparoscopic instrument attached to a laparoscope and a glove-wound retractor umbilical port, we performed solo surgeon SPLS in 13 patients between March 2011 and June 2012. Intraoperative complications and postoperative surgical outcomes were determined. The primary operative procedures performed were unilateral salpingo-oophorectomy (n = 5), unilateral salpingectomy (n = 2), adhesiolysis (n = 1), and laparoscopically assisted vaginal hysterectomy (n = 5). Additional surgical procedures included additional adhesiolysis (n = 4) and ovarian drilling (n = 1).The primary indications for surgery were benign ovarian tumors (n = 5), ectopic pregnancy (n = 2), pelvic adhesion (infertility) (n = 1), and benign uterine tumors (n = 5). Solo surgeon SPLS was successfully accomplished in all procedures without a laparoscopic assistant. There were no intraoperative or postoperative complications. Our laparoscope-anchored instrument system obviates the need for an additional laparoscopic assistant and enables SPLS to be performed by a solo surgeon. The findings show that with our system, solo surgeon SPLS is a feasible and safe alternative technique for the treatment of benign gynecologic diseases in properly selected patients.

Extramucosal pancreaticojejunostomy at laparoscopic pancreaticoduodenectomy

Servet Karagul

Full Text Available While the 'best pancreatic anastomosis technique' debate is going during Whipple procedure, the laparoscopic pancreaticoduodenectomy lately began to appear more and more often in the medical literature. All the popular anastomosis techniques used in open pancreas surgery are being experienced in laparoscopic pancreaticoduodenectomy. However, when they were adapted to laparoscopy, their implementation was not technically easy, and assistance of robotic surgery was sometimes required at the pancreatic anastomosis stage of the procedure. Feasibility and simplicity of a new technique have a vital role in its adaptation to laparoscopic surgery. We frequently use the extra-mucosal single row handsewn anastomosis method in open and laparoscopic surgery of the stomach, small and large bowel and we found it easy and reliable. Here, we defined the adaptation of this technique to the laparoscopic pancreas anastomosis. The outcomes were not inferior to the other previously described techniques and it has the advantage of simplicity.

Surgical trials have typically experienced recruitment difficulties when compared with other types of oncology trials. Qualitative studies have an important role to play in exploring reasons for low recruitment, although to date few such studies have been carried out that are embedded in surgical trials. The BOLERO trial (Bladder cancer: Open versus Lapararoscopic or RObotic cystectomy) is a study to determine the feasibility of randomisation to open versus laparoscopic access/robotic cystectomy in patients with bladder cancer. We describe the results of a qualitative study embedded within the clinical trial that explored why patients decline randomisation. Ten semi-structured interviews with patients who declined randomisation to the clinical trial, and two interviews with recruiting research nurses were conducted. Data were analysed for key themes. The majority of patients declined the trial because they had preferences for a particular treatment arm, and in usual practice could choose which surgical method they would be given. In most cases the robotic option was preferred. Patients described an intuitive 'sense' that favoured the new technology and had carried out their own inquiries, including Internet research and talking with previous patients and friends and family with medical backgrounds. Medical histories and lifestyle considerations also shaped these personalised choices. Of importance too, however, were the messages patients perceived from their clinical encounters. Whilst some patients felt their surgeon favoured the robotic option, others interpreted 'indirect' cues such as the 'established' reputation of the surgeon and surgical method and comments made during clinical assessments. Many patients expressed a wish for greater direction from their surgeon when making these decisions. For trials where the 'new technology' is available to patients, there will likely be difficulties with recruitment. Greater attention could be paid to how messages about

Full Text Available Objective: Most laparoscopic surgeons have attempted to reduce incisional morbidity and improve cosmetic outcomes by using less and smaller trocars. Single incision laparoscopic splenectomy is a new laparoscopic procedure. Herein we would like to present our experiences.Material and Methods: Between January 2009 and June 2009, data of the 7 patients who underwent single incision laparoscopic splenectomy were evaluated retrospectively.Results: There were 7 patients (5 females and 2 males with a mean age of 29.9 years. The most common splenectomy indication was idiopathic thrombocytopenic purpura. Single incision laparoscopic splenectomy was performed successfully in 6 patients. In one patient the operation was converted to an open procedure.Conclusion: With surgeons experienced in minimally invasive surgery, single incision laparoscopic splenectomy could be performed successfully. However, in order to demonstrate the differneces between standard laparoscopic splenectomy and SILS splenetomy, prospective randomized comparative studies are required.

Do laparoscopic skills transfer to robotic surgery?

Panait, Lucian; Shetty, Shohan; Shewokis, Patricia A; Sanchez, Juan A

2014-03-01

Identifying the set of skills that can transfer from laparoscopic to robotic surgery is an important consideration in designing optimal training curricula. We tested the degree to which laparoscopic skills transfer to a robotic platform. Fourteen medical students and 14 surgery residents with no previous robotic but varying degrees of laparoscopic experience were studied. Three fundamentals of laparoscopic surgery tasks were used on the laparoscopic box trainer and then the da Vinci robot: peg transfer (PT), circle cutting (CC), and intracorporeal suturing (IS). A questionnaire was administered for assessing subjects' comfort level with each task. Standard fundamentals of laparoscopic surgery scoring metric were used and higher scores indicate a superior performance. For the group, PT and CC scores were similar between robotic and laparoscopic modalities (90 versus 90 and 52 versus 47; P > 0.05). However, for the advanced IS task, robotic-IS scores were significantly higher than laparoscopic-IS (80 versus 53; P robotic-PT score when compared with laparoscopic-PT (92 versus 105; P  0.05). The robot was favored over laparoscopy for all drills (PT, 66.7%; CC, 88.9%; IS, 94.4%). For simple tasks, participants with preexisting skills perform worse with the robot. However, with increasing task difficulty, robotic performance is equal or better than laparoscopy. Laparoscopic skills appear to readily transfer to a robotic platform, and difficult tasks such as IS are actually enhanced, even in subjects naive to the technology. Copyright © 2014 Elsevier Inc.

Studies using conventional consoles have suggested a possible link between video-gaming and laparoscopic skill. The authors hypothesized that the Nintendo Wii, with its motion-sensing interface, would provide a better model for laparoscopic tasks. This study investigated the relationship between Nintendo Wii skill, prior gaming experience, and laparoscopic skill. In this study, 20 participants who had minimal experience with either laparoscopic surgery or Nintendo Wii performed three tasks on a Webcam-based laparoscopic simulator and were assessed on three games on the Wii. The participants completed a questionnaire assessing prior gaming experience. The score for each of the three Wii games correlated positively with the laparoscopic score (r = 0.78, 0.63, 0.77; P skill overlap between the Nintendo Wii and basic laparoscopic tasks. Surgical candidates with advanced Nintendo Wii ability may possess higher baseline laparoscopic ability.

[Key vessels assessment and operation highlights in laparoscopic extended right hemicolectomy].

Laparoscopic radical colectomies have been more widely used gradually, among which laparoscopic extended right hemicolectomy is considered as the most difficult procedure. The difficulty of extended right hemicolectomy lies in the need to dissect lymph nodes along the superior mesenteric vein (SMV) and disconnect numerous and possible aberrant vessels. To address this problem, we emphasize two points in key vessel assessment: getting familiar with the anatomy along the medial-to-lateral approach and having a good understanding about the preoperative imaging presentations. An accurately preoperative imaging assessment by abdominal enhanced CT can help the surgeon understand the relative position of the key vessels to be dealt with during operation and the situation of the possible aberrant vessels so as to guide the procedure more effectively and facilitate the prevention and management of the intraoperative complications. During operation, the operator should pay special attention to the management of the vessels in the ileocolic vessel region, Henle's trunk and middle colon vessels. The operation highlights of the key vessels are as follows: (1) The ileocolic vessels: identifying the Toldt's gap correctly and opening the vascular sheath of the SMV securely; making sure that the duodenum is well protected. (2) Henle's trunk: dissecting along the surface of the Henle's trunk; preserving the anterior superior pancreaticoduodenal vein (ASPDV) and main trunk of the Henle's trunk; disconnecting the roots of the right colic vein (RCV) and right gastroepiploic vein (RGEV), and then dissecting lymph nodes along the surface of the pancreas. (3) The middle colon vessels: identifying the root of the middle colon vessel along the lower edge of the pancreas; avoiding entering behind the pancreas; mobilizing the transverse mesocolon sufficiently along the surface of the pancreas. Finally, we discuss and analyze the disputes currently existing in laparoscopic extended right

The use of laparoscopy has been established in improving perioperative and postoperative outcomes for patients with simple appendicitis. Laparoscopic appendectomy is associated with less wound pain, less wound infection, a shorter hospital stay, and faster overall recovery when compared to the open appendectomy for uncomplicated cases. In the past two decades, the use of laparoscopy for the treatment of perforated appendicitis to take the advantages of minimally invasiveness has increased. This article reviewed the prevalence, approaches, safety disclaimers, perioperative and postoperative outcomes of the laparoscopic appendectomy in the treatment of patients with perforated appendicitis. Special issues including the conversion, interval appendectomy, laparoscopic approach for elderly or obese patient are also discussed to define the role of laparoscopic treatment for patients with perforated appendicitis.

The concept of reducing the number of transabdominal access ports has been criticized for violating basic tenets of traditional multiport laparoscopy. Potential benefits of reduced port surgery may include decreased pain, improved cosmesis, less hernia formation, and fewer wound complications. However, technical challenges associated with these access methods have not been adequately addressed by advancement in instrumentations. We describe our initial experience with the NovaTract™ Laparoscopic Dynamic Retractor. A retrospective review of all patients who underwent two-port laparoscopic cholecystectomy between 2013 and 2014 using the NovaTract retractor was performed. The patients were equally divided into three groups (Group A, B, C) based on the order of case performed. Eighteen consecutive patients underwent successful two-port laparoscopic cholecystectomy for symptomatic cholelithiasis. Mean age was 39.9 years and mean body mass index was 28.1 kg/m(2) (range 21-39.4). Overall mean operative time was 65 minutes (range 42-105), with Group A of 70 minutes, Group B of 65 minutes, and Group C of 58 minutes (P = .58). All cases were completed laparoscopically using the retraction system, without a need for additional ports or open conversion. No intra- or postoperative complications were seen. All patients were discharged on the same day of surgery. No mortality found in this series. The NovaTract laparoscopic dynamic retractor is safe and easy to use, which is reflected by acceptable operative time for a laparoscopic cholecystectomy using only two ports. The system allows surgical approach to mimic the conventional laparoscopic techniques, while eliminating or reducing the number of retraction ports.

Full Text Available Abstract Introduction Chylous ascites may result from diverse pathologies. Ascites results either due to blockage of the lymphatics or leak secondary to inadvertent trauma during surgery. Case presentation We report the first case of chylous ascites following radical nephrectomy for a renal cell carcinoma involving the right half of a crossed fused renal ectopia. The patient was managed conservatively. Conclusion Post-operative chylous ascites is a rare complication of retroperitoneal and mediastinal surgery. Most cases resolve with conservative treatment which aims at decreasing lymph production and optimizing nutritional requirements along with palliative measures. Refractory cases need either open or laparoscopic ligation of the leaking lymphatic channels. A review of the current literature on the management of post-operative chylous ascites is presented.

Introduction: While the effects of increasing body mass index on prostate cancer epidemiology and surgical approach have recently been studied, its effects on surgical outcomes are less clear. We studied the perioperative outcomes of obese (BMI >= 30) men treated with daVinci-assisted laparoscopic radical prostatectomy (DLP) and compared them to those treated with open radical retropubic prostatectomy (RRP) in a contemporary time frame. Method: After Institutional Review Board approval, we used the Mayo Clinic Radical Prostatectomy database to identify patients who had undergone DLP by a single surgeon and those who had undergone open RRP by a single surgeon between December 2002 and March 2005. Baseline demographics, peri- and post-operative courses, and complications were collected by retrospective chart review, and variables from the two cohorts compared using chi-square method and least-squares method of linear regression where appropriate. Results: 59 patients who had DLP and 76 undergoing RRP were available for study. Baseline demographics were not statistically different between the two cohorts. Although DLP had a significantly lower clinical stage than RRP (p=0.02), pathological stage was not statistically different (p=0.10). Transfusion rates, hospital stay, overall complications, and pathological Gleason were also not significantly different, nor were PSA progression, positive margin rate, or continence at 1 year. After bilateral nerve-sparing, erections suitable for intercourse with or without therapy at 1 year was 88.5% (23/26) for DLP and 61.2% (30/49) for RRP (p=0.01). Follow-up time was similar. Conclusion: For obese patients, DLP appears to have similar perioperative, as well as short-term oncologic and functional outcomes when compared to open RRP.

Pedicle omental graft created by laparoscopic surgery for filling a radiation-induced ulcer in a woman with breast cancer

In patients with advanced or recurrent breast cancer, it is difficult to reconstruct chest wall ulcers due to postoperative irradiation, which is often infected. We present a laparoscopic technique for creating and mobilizing an omental flap. A 63-year-old woman diagnosed with parasternal lymph node metastases from left breast cancer 11 months after standard radical mastectomy underwent lymph node resection with radiation therapy. She developed ulceration of the irradiated chest wall 3 years and 10 months later. An omental flap obtained by laparoscopy was used to fill the space after the radiation-induced ulcer was resected and covered with a free skin graft. The skin graft adapted to the omentum. This laparoscopic procedure is more cosmetrically acceptable and less invasive than laparotomy in obtaining the omentum while yielding equivalent results in chest wall reconstruction. (author)

Transanal vs laparoscopic total mesorectal excision for rectal cancer

DEFF Research Database (Denmark)

Perdawood, Sharaf; Al Khefagie, Ghalib Ali Abod

2016-01-01

BACKGROUND: Laparoscopic total mesorectal excision (LaTME) has improved short-term outcomes of rectal cancer surgery with comparable oncological results to open approach. LaTME can be difficult in the lower most part of the rectum, leading potentially to higher rates of complications, conversion...... to open surgery and probably suboptimal oncological quality. Transanal TME (TaTME) can potentially solve these problems. The aim of this study was to compare the short-term results after TaTME with those after LaTME. METHODS: A prospectively collected database of consecutive patients who underwent Ta......TME was maintained. Results were compared with those underwent LaTME in the preceding period. Patients who underwent low anterior resection or intersphincteric abdominoperineal excision (APE) were included. Primary end-points were radical resection and specimen quality. Secondary end-points were complications, rates...

Thromboelastography (TEG) is a technique that measures coagulation processes and surveys the properties of a viscoelastic blood clot, from its formation to lysis. To determine the possible hypercoagulability state and the effect of antithrombotic prophylaxis on thromboelastogram results and development of venous thrombosis during laparoscopic fundoplication. The study was performed on 106 patients who were randomized into two groups. The first group received low-molecular-weight heparin (LMWH) 12 h before the operation, and 6 and 30 h after it. The second group received LMWH only 1 h before the laparoscopic fundoplication. The TEG profile was collected before LMWH injection, 1 h after the introduction of the laparoscope and 15 min after the surgery was completed. There was no significant difference in thromboelastography R-time between the groups before low-molecular-weight heparin injection. In group I preoperative R-values significantly decreased 1 h after the introduction of the laparoscope, after the end of surgery and on the third postoperative day. K-time values decreased significantly on the third postoperative day compared with the results before low-molecular-weight heparin injection, and after the operation. In group II, preoperative R-values significantly decreased 1 h after the introduction of the laparoscope, and after surgery. K-time values did not change significantly during or after the laparoscopic operation. Our study results demonstrated that the hypercoagulation state (according to the TEG results) was observed during and after laparoscopic fundoplication in patients when LMWH was administered 12 h before the operation together with intraoperative intermittent pneumatic compression. The optimal anticoagulation was obtained when LMWH was administered 1 h before fundoplication.

Laparoscopic pelvic sling placement facilitates optimum therapeutic radiotherapy delivery in the management of pelvic malignancy.

LENUS (Irish Health Repository)

Joyce, M

2012-02-01

BACKGROUND: Radiotherapy has a significant role in the management of pelvic malignancies. However, the small intestine represents the main dose limiting organ. Invasive and non-invasive mechanical methods have been described to displace bowel out of the radiation field. We herein report a case series of laparoscopic placement of an absorbable pelvic sling in patients requiring pelvic radiotherapy. METHODS: Six patients were referred to our minimally invasive unit. Four patients required radical radiotherapy for localised prostate cancer, one was scheduled for salvage localised radiotherapy for post-prostatectomy PSA progression and one patient required adjuvant radiotherapy post-cystoprostatectomy for bladder carcinoma. All patients had excessive small intestine within the radiation fields despite the use of non-invasive displacement methods. RESULTS: All patients underwent laparoscopic mesh placement, allowing for an elevation of small bowel from the pelvis. The presence of an ileal conduit or previous surgery did not prevent mesh placement. Post-operative planning radiotherapy CT scans confirmed displacement of the small intestine allowing all patients to receive safely the planned radiotherapy in terms of both volume and radiation schedule. CONCLUSION: Laparoscopic mesh placement represents a safe and efficient procedure in patients requiring high-dose pelvic radiation, presenting with unacceptable small intestine volume in the radiation field. This procedure is also feasible in those that have undergone previous major abdominal surgery.

The authors evaluated the feasibility of a laparoscopic sentinel lymph node (SN) procedure with combined radioisotopic and patent blue labeling in patients with cervical carcinoma. Thirteen women (median age, 52.5 years) with cervical carcinoma (Stage Ia2 in 1 patient, Stage Ib1 in 10 patients, Stage Ib2 in 1 patient, and Stage IIa in 1 patient) underwent a laparoscopic SN procedure using an endoscopic gamma probe after both radioactive isotope and patent blue injections. After the procedure, all patients underwent complete laparoscopic pelvic lymphadenectomy and either laparoscopic radical hysterectomy (eight patients) or the Schauta-Amreich operation (five patients). SNs (mean, 1.7 SNs per patient; range, 1-3 SNs per patient) were identified in 12 of 13 patients. A median of 10.5 pelvic lymph nodes per patient (range, 4-17 pelvic lymph nodes per patient) were removed. No lymph node involvement was detected in SNs with hematoxylin and eosin staining. Immunohistochemical studies identified four metastatic SNs in two patients, with micrometastases in two SNs from the first patient and isolated tumor cells in two SNs from the second patient. No false-negative SN results were obtained. The results of this study suggest that SN detection with a combination of radiocolloid and patent blue is feasible in patients with cervical carcinoma. The combination of laparoscopy and the SN procedure permitted minimally invasive management of early-stage disease. Copyright 2003 American Cancer Society.

Laparoscopic suturing is an advanced skill that is difficult to acquire. Simulator-based skills curricula have been developed that have been shown to transfer to the operating room. Currently available skills curricula need to be optimized. We hypothesized that mastering basic laparoscopic skills first would shorten the learning curve of a more complex laparoscopic task and reduce resource requirements for the Fundamentals of Laparoscopic Surgery suturing curriculum. Medical students (n = 20) with no previous simulator experience were enrolled in an IRB-approved protocol, pretested on the Fundamentals of Laparoscopic Surgery suturing model, and randomized into 2 groups. Group I (n = 10) trained (unsupervised) until proficiency levels were achieved on 5 basic tasks; Group II (n = 10) received no basic training. Both groups then trained (supervised) on the Fundamentals of Laparoscopic Surgery suturing model until previously reported proficiency levels were achieved. Two weeks later, they were retested to evaluate their retention scores, training parameters, instruction requirements, and cost between groups using t-test. Baseline characteristics and performance were similar for both groups, and 9 of 10 subjects in each group achieved the proficiency levels. The initial performance on the simulator was better for Group I after basic skills training, and their suturing learning curve was shorter compared with Group II. In addition, Group I required less active instruction. Overall time required to finish the curriculum was similar for both groups; but the Group I training strategy cost less, with a savings of $148 per trainee. Teaching novices basic laparoscopic skills before a more complex laparoscopic task produces substantial cost savings. Additional studies are needed to assess the impact of such integrated curricula on ultimate educational benefit. Copyright (c) 2010 American College of Surgeons. Published by Elsevier Inc.

Laparoscopic adenomectomy is a feasible and effective surgical procedure. We have progressively simplified the procedure using barbed sutures and a technique we call "knotless" laparoscopic adenomectomy. We present a prospective, multicenter, descriptive study that reflects the efficacy and safety of this technique in an actual, reproducible clinical practice situation. A total of 26 patients with benign prostatic hyperplasia of considerable size (>80cc) underwent "knotless" laparoscopic adenomectomy. This is an extraperitoneal laparoscopic technique with 4 trocars based on the controlled and hemostatic enucleation of the adenoma using ultrasonic scalpels, precise urethral sectioning under direct vision assisted by a urethral plug, trigonization using barbed suture covering the posterior wall of the fascia, capsulorrhaphy with barbed suture and extraction of the morcellated adenoma through the umbilical incision. The median patient age was 69 (54-83)years, the mean prostate volume was 127 (89-245)cc, the mean operative time was 136 (90-315)min, the mean estimated bleeding volume was 200 (120-500)cc and the hospital stay was 3 (2-6)days. All patients experienced improved function in terms of uroflowmetry and International Prostate Symptom Score and quality of life questionnaires. There were complications in 6 patients, 5 of which were minor. "Knotless" laparoscopic adenomectomy is a procedure with low complexity that combines the advantages of open surgery (lasting functional results and complete extraction of the adenoma) with laparoscopic procedures (reduced bleeding and need for transfusions, shorter hospital stays and reduced morbidity and complications related to the abdominal wall). The use of ultrasonic scalpels and barbed sutures simplifies the procedure and enables a safe and hemostatic technique. Copyright © 2014 AEU. Publicado por Elsevier España, S.L.U.

Full Text Available Bladder outlet obstruction due to benign prostatic hyperplasia (BPH remains one of the most common problems of men in the advanced age group. Open prostatectomy for patients with large BPH is still the standard treatment recommended by the European Association of Urology and is performed quiet often. Disadvantages of this method of treatment are significant surgical trauma and high rate of perioperative complications . Laparoscopic modification of simple prostatectomy presents a worthy minimal invasive alternative to open surgical treatment of BPH. From November 2014 to December 2015, laparoscopic adenomectomy was performed for 16 patients. 7 (43.5% patients had transperitoneal (TP and 9 (56.25% patients had extraperitoneal (EP laparoscopic simple prostatectomy. None of the cases required conversion . All patients were discharged in satisfactory condition with complete restoration of free micturation. Laparoscopic prostatectomy as a method of surgical treatment for BPH can be easily reproducible. It can be adopted as a routine urological practice for large-sized BPH with the aim of minimizing operative trauma and achieving short hospital stay.

2017-09-01

Secondary bladder neck sclerosis represents one of the more frequent complications following endoscopic, open, and other forms of minimally invasive prostate surgery. Therapeutic decisions depend on the type of previous intervention (e.g., radical prostatectomy, TURP, HoLEP, radiotherapy, HIFU) and on associated complications (e.g., incontinence, fistula). Primary treatment in most cases represents an endoscopic bilateral incision. No specific advantages of any type of the applied energy (i.e., mono-/bipolar HF current, cold incision, holmium/thulium YAG laser) could be documented. Adjuvant measures such as injection of corticosteroids or mitomycin C have not been helpful in clinical routine. In case of first recurrence, a transurethral monopolar or bipolar resection can usually be performed. Recently, the ablation of the scared tissue using bipolar vaporization has been recommended providing slightly better long-term results. Thereafter, surgical reconstruction is strongly recommended using an open, laparoscopic, or robot-assisted approach. Depending on the extent of the bladder neck sclerosis and the underlying prostate surgery, a Y-V/T-plasty, urethral reanastomosis, or even a radical prostatectomy with new urethravesical anastomosis should be performed. Stent implantation should be reserved for patients who are not suitable for surgery. The final palliative measure is a cystectomy with urinary diversion or a (continent) cystostomy.

The laparoscopic approach in colorectal complications is controversial because of its difficulty. However, it has been proven that it can provide advantages over open surgery. The aim of this study is to compare laparoscopic approach in reoperations for complications after colorectal surgery with the open approach taking into account the severity of the patient prior to reoperation. Patients who underwent laparoscopic colorectal surgery from January 2006 to December 2015 were retrospectively reviewed. Patients requiring urgent surgical procedures for complications in the postoperative period were divided in two groups: laparoscopic surgery (LS) and open surgery (OS). To control clinical severity prior to reoperation, The Mannheim Peritonitis Index (MPI) was calculated. A total of 763 patients were studied, 40 required urgent surgery (24 OS/16 LS). More ileostomies were performed in the LS group (68.7% vs. 29.2%) and more colostomies in the OS group (37.5% vs. 6.2%), pstart of oral tolerance and less surgical wound infection (pstart of oral tolerance and a lower abdominal wall complication rate in patients with low severity index.

Laparoscopic adrenalectomy: Single centre experience.

LENUS (Irish Health Repository)

O'Farrell, N J

2012-02-01

BACKGROUND: Laparoscopic adrenalectomy is an attractive alternative to the traditional open approach in the surgical excision of an adrenal gland. It has replaced open adrenalectomy in our institution and we review our experience to date. METHODS: All cases of laparoscopic adrenalectomies in our hospital over eight years (from 2001 to May 2009) were retrospectively reviewed. Patient demographics, diagnosis, length of hospital stay, histology and all operative and post-operative details were evaluated. RESULTS: Fifty-five laparoscopic adrenalectomies (LA) were performed on 51 patients over eight years. The mean age was 48 years (Range 16-86 years) with the male: female ratio 1:2. Twenty-three cases had a right adrenalectomy, 24 had a left adrenalectomy and the remaining four patients had bilateral adrenalectomies. 91% were successfully completed laparoscopically with five converted to an open approach. Adenomas (functional and non functional) were the leading indication for LA, followed by phaeochromocytomas. Other indications for LA included Cushing\\'s disease, adrenal malignancies and rarer pathologies. There was one mortality from necrotising pancreatitis following a left adrenalectomy for severe Cushing\\'s disease, with subsequent death 10 days later. CONCLUSION: Laparoscopic adrenalectomy is effective for the treatment of adrenal tumours, fulfilling the criteria for the ideal minimally invasive procedure. It has replaced the traditional open approach in our centre and is a safe and effective alternative. However, in the case of severe Cushing\\'s disease, laparoscopic adrenalectomy has the potential for significant adverse outcomes and mortality.

Appendicovesicostomy is commonly employed to facilitate drainage of urine through the catheter. Due to the tendency to less invasive procedures for the treatment of patients with neurogenic bladder, laparoscopy has been used as an alternative to open surgery, with the immediate advantages of postoperative recovery, shorter postoperative ileus, better cosmetic results, lower postoperative pain and early reintegration into everyday life. Compare the results of laparoscopic procedure with open appendicovesicostomy. We conducted an observational, analytical, longitudinal, ambispective cohort study, which included patients from 6-16 years of age diagnosed with neurogenic bladder, operated through laparoscopic and open appendicovesicostomy from January 2009 to June 2013. Information was obtained from clinical records. Six patients were operated laparoscopically and 14 by open approach. Surgical time was longer and statistically significant in the laparoscopic group with a median of 330 min (300-360 min) compared to open procedure of 255 min (180-360 min). Seven patients had complications in the open group and only one in the laparoscopic group. The difference in the dose of analgesics and time of use was statistically significant in favor of the laparoscopic group. The degree of urinary continence through the stoma was higher for laparoscopic (100%) compared to the open procedure (64%). In neurogenic bladder with urodynamic bladder capacity and leak point pressure bladder within acceptable values, laparoscopic appendicovesicostomy was a better alternative.

Full Text Available Introduction: Laparoscopic cholecystectomy has clearly become the choice over open cholecystectomy in the treatment of hepatobiliary disease since its introduction by Mouret in 1987. This study evaluates a series of patients with chronic calculus cholecystitis who were treated with laparoscopic and open cholecystectomy and assesses the outcomes of both techniques. Objective: To evaluate the efficacy of laparoscopic vs open cholecystectomy in chronic calculus cholecystitis and establish the out-comes of this treatment modality at Lumbini Medical College and Teaching Hospital. Methods: This was a retrospective analysis over a one-year period (January 1, 2012 to December 31, 2012, per-formed by single surgeon at Lumbini Medical College and Teaching Hospital located midwest of Nepal. 166 patients underwent surgical treatment for chronic calculus cholecystitis. Patients included were only chronic calculus cholecystitis proven histopathologocally and the rest were excluded. Data was collected which included patients demographics, medical history, presentation, complications, conversion rates from laparoscopic. cholecystectomy to open cholecystectomy, operative and postoperative time. Results: Patients treated with laparoscopic cholecystectomy for chronic calculus cholecystitis had shorter operating times and length of stay compared to patients treated with open cholecystectomy for chronic calculus cholecystitis. Conversion rates were 3.54% in chronic calculus cholecystitis during the study period. Complications were also lower in patients who underwent laparoscopic cholecystectomy versus open cholecystectomy for cholelithiasis. Conclusions: Laparoscopic cholecystectomy appears to be a reliable, safe, and cost-effective treatment modality for chronic calculus cholecystitis.

Full Text Available The present study is undertaken to establish the usefulness of laparoscopic cholecystectomy and to know its merits and demerits as compared to open cholecystectomy in children. In all, 28 patients who underwent cholecystectomy (8 open and 20 laparoscopic cholecystectomy in B.Y.L. Nair hospital between July 1999 and March 2004 were analyzed. Calculous cholecystitis was found to be the most common indication for surgery. Operative time for laparoscopic cholecystectomy was more than that in open cholecystectomy in the early phase of laparoscopy, which got reduced as we gained experience. The requirement of parenteral antibiotics and analgesics and the duration of stay were significantly shorter with laparoscopy. The advantages for a child in laparoscopic cholecystectomy as compared to open cholecystectomy are minimal pain, avoidance of an upper abdominal incision, cosmesis and shorter duration of hospitalization with quick return to home and school. Thus, laparoscopic cholecystectomy is safe and efficacious in children.

Full Text Available ABSTRACT Objective: The purpose of this video is to present the laparoscopic repair of a VUF in a 42-year-old woman, with gross hematuria, in the immediate postoperative phase following a cesarean delivery. The obstetric team implemented conservative management, including Foley catheter insertion, for 2 weeks. She subsequently developed intermittent hematuria and cystitis. The urology team was consulted 15 days after cesarean delivery. Cystoscopy indicated an ulcerated lesion in the bladder dome of approximately 1.0cm in size. Hysterosalpingography and a pelvic computed tomography scan indicated a fistula. Materials and Methods: Laparoscopic repair was performed 30 days after the cesarean delivery. The patient was placed in the lithotomy position while also in an extreme Trendelenburg position. Pneumoperitoneum was established using a Veress needle in the midline infra-umbilical region, and a primary 11-mm port was inserted. Another 11-mm port was inserted exactly between the left superior iliac spine and the umbilicus. Two other 5-mm ports were established under laparoscopic guidance in the iliac fossa on both sides. The omental adhesions in the pelvis were carefully released and the peritoneum between the bladder and uterus was incised via cautery. Limited cystotomy was performed, and the specific sites of the fistula and the ureteral meatus were identified; thereafter, the posterior bladder wall was adequately mobilized away from the uterus. The uterine rent was then closed using single 3/0Vicryl sutures and two-layer watertight closure of the urinary bladder was achieved by using 3/0Vicryl sutures. An omental flap was mobilized and inserted between the uterus and the urinary bladder, and was fixed using two 3/0Vicryl sutures, followed by tube drain insertion. Results: The operative time was 140 min, whereas the blood loss was 100ml. The patient was discharged 3 days after surgery, and the catheter was removed 12 days after surgery

Higher morbidity in total gastrectomy than in distal gastrectomy has been reported, but laparoscopic subtotal gastrectomy (LsTG) has been reported to be safe and feasible in early gastric cancer (GC). We determined the surgical, nutritional and oncological outcomes of LsTG for advanced gastric cancer (AGC). Of the 816 consecutive patients with GC who underwent radical gastrectomy at our institution between 2008 and 2012, 253 who underwent curative laparoscopic gastrectomy (LG) for AGC were enrolled. LsTG was indicated for patients with upper stomach third tumors, who hoped to avoid total gastrectomy, nutritional status were primarily assessed. Of 253 patients, the morbidity (Clavien-Dindo classification grade ≥ III) was 17.0% (43 patients). The 3-year overall survival and 3-year recurrence-free survival rates were 80.2 and 73.5%, respectively. LcDG, LsTG and LTG were performed in 121, 27 and 105 patients, individually. Morbidity was strongly associated with LTG (P = 0.001). Postoperative loss of body weight was significantly greater after LTG in comparison with LcDG or LsTG (P nutritional point of view.

2010-01-01

Full Text Available Laparoscopic inguinal herniorraphy via a transabdominal preperitoneal (TAPP approach using Polypropylene Mesh (Mesh and staples is an accepted technique. Mesh induces a localised inflammatory response that may extend to, and involve, adjacent abdominal and pelvic viscera such as the appendix. We present an interesting case of suspected Mesh-induced appendicitis treated successfully with laparoscopic appendicectomy, without Mesh removal, in an elderly gentleman who presented with symptoms and signs of acute appendicitis 18 months after laparoscopic inguinal hernia repair. Possible mechanisms for Mesh-induced appendicitis are briefly discussed.

Minimally invasive surgery has been replacing the open standard technique in several procedures. Similar or even better postoperative outcomes have been described in laparoscopic or robot-assisted procedures when compared to open surgery. Moreover, minimally invasive surgery has been providing less postoperative pain, shorter hospitalization, and thus a faster return to daily activities. However, the learning curve required to obtain laparoscopic expertise has been a barrier in laparoscopic spreading. Laparoscopic surgery training laboratory has been developed to aid surgeons to overcome the challenging learning curve. It may include tutorials, inanimate model skills training (box models and virtual reality simulators), animal laboratory, and operating room observation. Several different laparoscopic courses are available with specific characteristics and goals. Herein, we aim to describe the activities performed in a dry and animal-model training laboratory and to evaluate the impact of different kinds of laparoscopic surgery training courses on surgeon’s performance. Several tasks are performed in dry and animal laboratory to reproduce a real surgery. A short period of training can improve laparoscopic surgical skills, although most of times it is not enough to confer laparoscopic expertise for participants. Nevertheless, this short period of training is able to increase the laparoscopic practice of surgeons in their communities. Full laparoscopic training in medical residence or fellowship programs is the best way of stimulating laparoscopic dissemination. PMID:27933135

This study reviews our experience with laparoscopic cholecystectomy in the treatment of cholelithiasis in transplant patients. Demographic data, medications used, and operative and postoperative data of all transplant recipients who were subjected to laparoscopic cholecystectomy for cholelithiasis at our hospital were obtained. A total of 15 transplant patients (13 renal transplantation and 2 bone marrow transplantation) underwent laparoscopic cholecystectomy. All patients were admitted to the hospital on the day of the operation. The immunosuppressive regimen was not modified during hospitalization. Clinical presentation of cholelithiasis was biliary colicky (n=12), acute cholecystitis (n=2), and jaundice (n=1). The operation was uneventful in all patients. Postoperative complications were nausea and vomiting in 2 patients, prolonged tracheal intubation in 1, wound infection in 1 and large superficial hematoma in 1 patient. Laparoscopic cholecystectomy is associated to a low morbidity and mortality and good postoperative outcome in transplant patients with uncomplicated cholecystitis.

The application of laparoscopy for liver surgery is rapidly increasing and the past few years have demonstrated a shift in paradigm with a trend towards more extended and complex resections. The development of instruments and technical refinements with the effective use of magnified caudal laparoscopic views have contributed to the ability to overcome the limitation of laparoscopic liver resection. The Endoscopic and Laparoscopic Surgeons of Asia (ELSA) Visionary Summit 2017 and the 3 rd Expert Forum of Asia-Pacific Laparoscopic Hepatectomy organized hepatobiliary pancreatic sessions in order to exchange surgical tips and tricks and discuss the current status and future perspectives of laparoscopic hepatectomy. This report summarizes the oral presentations given at the 3 rd Expert Forum of Asia-Pacific Laparoscopic Hepatectomy.

To estimate readmission rates and emergency care use by patients discharged home the same day after laparoscopic hysterectomy. This was a retrospective case series of patients discharged home the same-day after total or supracervical laparoscopic hysterectomy in a managed care setting. Chart reviews were performed for outcomes of interest which included readmission rates, emergency visits, and surgical and demographic characteristics. The two hysterectomy groups were compared using χ² tests for categorical variables and t tests or Wilcoxon rank-sum tests for continuously measured variables. One-thousand fifteen laparoscopic hysterectomies were performed during the 3-year study period. Fifty-two percent (n=527) of the patients were discharged home the same-day; of those, 46% (n=240) had total laparoscopic hysterectomies and 54% (n=287) had supracervical. Cumulative readmission rates were 0.6%, 3.6%, and 4.0% at 48 hours, 3 months, and 12 months, respectively. The most common readmission diagnoses included abdominal incision infection, cuff dehiscence, and vaginal bleeding. Less than 4% of patients presented for emergency care within 48 or 72 hours, most commonly for nausea or vomiting, pain, and urinary retention. Median uterine weight was 155 g, median blood loss was 70 mL, and median surgical time was 150 minutes. There was no difference in readmission rates or emergency visits for the total compared with the supracervical laparoscopic hysterectomy group. Same-day discharge after laparoscopic hysterectomy is associated with low readmission rates and minimal emergency visits in the immediate postoperative period. Same-day discharge may be a safe option for healthy patients undergoing uncomplicated laparoscopic hysterectomy.

Involuntary release of urine during sexual climax, orgasm-associated urinary incontinence, occurs frequently after radical prostatectomy. We know little about its prevalence and its effect on sexual satisfaction. To determine the prevalence of orgasm-associated incontinence after radical prostatectomy and its effect on sexual satisfaction. Consecutive series, follow-up at one point in calendar time of men having undergone radical prostatectomy (open surgery or robot-assisted laparoscopic surgery) at Karolinska University Hospital, Stockholm, Sweden, 2002-2006. Of the 1,411 eligible men, 1,288 (91%) men completed a study-specific questionnaire. Prevalence rate of orgasm-associated incontinence. Of the 1,288 men providing information, 691 were sexually active. Altogether, 268 men reported orgasm-associated urinary incontinence, of whom 230 (86%) were otherwise continent. When comparing them with the 422 not reporting the symptom but being sexually active, we found a prevalence ratio (with 95% confidence interval) of 1.5 (1.2-1.8) for not being able to satisfy the partner, 2.1 (1.1-3.5) for avoiding sexual activity because of fear of failing, 1.5 (1.1-2.1) for low orgasmic satisfaction, and 1.4 (1.2-1.7) for having sexual intercourse infrequently. Prevalence ratios increase in prostate-cancer survivors with a higher frequency of orgasm-associated urinary incontinence. We found orgasm-associated urinary incontinence to occur among a fifth of prostate cancer survivors having undergone radical prostatectomy, most of whom are continent when not engaged in sexual activity. The symptom was associated with several aspects of sexual life. © 2011 International Society for Sexual Medicine.

Robotic-assisted laparoscopic partial nephrectomy: initial experience in Brazil and a review of the literature

Full Text Available CONTEXT AND PURPOSE: Partial nephrectomy has become the standard of care for renal tumors less than 4 cm in diameter. Controversy still exists, however, regarding the best surgical approach, especially when minimally invasive techniques are taken into account. Robotic-assisted laparoscopic partial nephrectomy (RALPN has emerged as a promising technique that helps surgeons achieve the standards of open partial nephrectomy care while offering a minimally invasive approach. The objective of the present study was to describe our initial experience with robotic-assisted laparoscopic partial nephrectomy and extensively review the pertinent literature. MATERIALS AND METHODS: Between August 2009 and February 2010, eight consecutive selected patients with contrast enhancing renal masses observed by CT were submitted to RALPN in a private institution. In addition, we collected information on the patients' demographics, preoperative tumor characteristics and detailed operative, postoperative and pathological data. In addition, a PubMed search was performed to provide an extensive review of the robotic-assisted laparoscopic partial nephrectomy literature. RESULTS: Seven patients had RALPN on the left or right sides with no intraoperative complications. One patient was electively converted to a robotic-assisted radical nephrectomy. The operative time ranged from 120 to 300 min, estimated blood loss (EBL ranged from 75 to 400 mL and, in five cases, the warm ischemia time (WIT ranged from 18 to 32 min. Two patients did not require any clamping. Overall, no transfusions were necessary, and there were no intraoperative complications or adverse postoperative clinical events. All margins were negative, and all patients were disease-free at the 6-month follow-up. CONCLUSIONS: Robotic-assisted laparoscopic partial nephrectomy is a feasible and safe approach to small renal cortical masses.Further prospective studies are needed to compare open partial nephrectomy with

No criteria define indications for laparoscopic splenectomy in trauma. This investigation compared characteristics of trauma patients and outcomes between laparoscopic and open splenectomies. Patients were identified retrospectively by using ICD-9 codes. Included patients were 18 or older, with a blunt splenic injury from January 1, 2011, through December 31, 2014, and required splenectomy. Excluded patients had penetrating trauma, successful nonoperative management, or successful embolization. Variables included demographics, presenting characteristics, injury severity scores, abdominal abbreviated injury scores, splenic injury grade, surgical indication and approach (open or laparoscopic), surgery length, intra-operative blood loss, transfusions, length of stay, complications, mortality, and discharge disposition. Forty-one patients underwent open splenectomy, and 11 underwent laparoscopic splenectomy. The mean age was 48.7 years, and men comprised the sample majority (36/52). The groups were well matched for age, abdominal injury scores, and admission vital signs. The open group had a significantly lower level of consciousness and more acidosis compared with the laparoscopic group. Most laparoscopic splenectomies were performed after failed nonoperative management or embolization. The indications for open splenectomy were a positive focused assessment with sonography for trauma and computed tomography results. Laparoscopic patients had significantly longer times between presentation and surgery and longer operations, but had significantly less blood loss and fewer transfusions compared with the open group. There were no differences in mortality, length of stay, complications, or discharge dispositions. Laparoscopic splenectomy is useful in patients with blunt trauma in whom conservative management produced no improvement and who do not have other injuries to preclude laparoscopy.

To show a new technique of laparoscopic intracorporeal anastomosis for transrectal bowel resection with transvaginal specimen extraction, a technique particularly suited for treatment of bowel endometriosis. Step-by-step explanation of the technique using videos and pictures (educative video). Endometriosis may affect the bowel in 3% to 37% of all endometriosis cases. Bowel endometriosis affects young women, without any co-morbidities and in particular without any vascular disorders. In addition, affected patients often express a desire for childbearing. Radical excision is sometimes required because of the impossibility of conservative treatment such as shaving, mucosal skinning, or discoid resection. Bowel endometriosis should not be considered a cancer, and consequently maximal resection is not the objective. Rather, the goal would be to achieve functional benefit. As a result, resection must be as economic and cosmetic as possible. The laparoscopic approach has proved its superiority over the open technique, although mini-laparotomy is generally performed to prepare for the anastomosis. Total laparoscopic approach in patients with partial bowel stenosis, using the vagina for specimen extraction. This technique of intracorporeal anastomosis with transvaginal specimen extraction enables a smaller resection and avoidance of abdominal incision enlargement that may cause hernia, infection, or pain. When stenosis is partial, this technique seems particularly suited for treatment of bowel endometriosis requiring resection. If stenosis is complete, the anvil can be inserted above the lesion transvaginally. Copyright © 2013 AAGL. Published by Elsevier Inc. All rights reserved.

Radical trachelectomy is the treatment of choice in women with early-stage cervical cancer wishing to preserve fertility. Radical trachelectomy can be performed with a vaginal, abdominal, or laparoscopic/robotic approach. Vaginal radical trachelectomy (VRT) is generally not offered to patients with tumors 2cm or larger because of a high recurrence rate. There are no conclusive recommendations regarding the safety of abdominal radical trachelectomy (ART) or laparoscopic radical trachelectomy (LRT) in such patients. Several investigators have used neoadjuvant chemotherapy in patients with tumors 2 to 4cm to reduce tumor size so that fertility preservation may be offered. However, to our knowledge, no published study has compared outcomes between patients with cervical tumors 2cm or larger who underwent immediate radical trachelectomy and those who underwent neoadjuvant chemotherapy followed by radical trachelectomy. We conducted a literature review to compare outcomes with these 2 approaches. Our main endpoints for evaluation were oncological and obstetrical outcomes. The fertility preservation rate was 82.7%, 85.1%, 89%; and 91.1% for ART (tumors larger than >2cm), ART (all sizes), NACT followed by surgery and VRT (all sizes); respectively. The global pregnancy rate was 16.2%, 24% and 30.7% for ART, VRT, and NACT followed by surgery; respectively. The recurrence rate was 3.8%, 4.2%, 6%, 7.6% and 17% for ART (all sizes), VRT (all sizes), ART (tumors>2cm), NACT followed by surgery, and VRT (tumors>2cm). These outcomes must be considered when offering a fertility sparing technique to patients with a tumor larger than 2cm. Copyright © 2015 Elsevier Inc. All rights reserved.

We report a case of endometriosis in the right inguinal region, attached to the right round ligament in a 28-year-old woman. At the age of 20, laparoscopic left ovarian cystectomy and pelvic adhesiolysis for endometriosis was carried out. She noticed a right tender groin mass 7 months previously, and the tumour size fluctuated with the menstrual cycle. A poorly circumscribed elastic hard mass, measuring 3 cm in diameter, was palpated in her right inguinal region. Magnetic resonance imaging showed a 2.5 cm x 2.5 cm mass in the right inguinal canal and a 5.4 cm x 6.8 cm mass was seen in the left ovary. The mass enlarged during menstruation. The groin mass was removed, in addition to carrying out laparoscopic ovarian cystectomy. At operation, the groin mass was found to be in continuity with the round ligament of extraperitoneal portion. Histological diagnosis of endometriosis was made in both ovarian and inguinal tumours. After surgery, the pain disappeared completely. Worth mentioning is that MRI clearly showed the change of tumour size depending on the menstrual cycle, which aided in arriving at the correct diagnosis of endometriosis in an unusual location

Single-incision total laparoscopic hysterectomy

Directory of Open Access Journals (Sweden)

Sinha Rakesh

2011-01-01

Full Text Available Single-incision laparoscopic surgery is an alternative to conventional multiport laparoscopy. Single-access laparoscopy using a transumbilical port affords maximum cosmetic benefits because the surgical incision is hidden in the umbilicus. The advantages of single-access laparoscopic surgery may include less bleeding, infection, and hernia formation and better cosmetic outcome and less pain. The disadvantages and limitations include longer surgery time, difficulty in learning the technique, and the need for specialized instruments. Ongoing refinement of the surgical technique and instrumentation is likely to expand its role in gynecologic surgery in the future. We perform single-incision total laparoscopic hysterectomy using three ports in the single transumbilical incision.

2014-08-01

Full Text Available Background: Severe abdominal pain is not common after laparoscopic surgeries, but acute or chronic pain after operation is considerable in some patients. Post-operative Pain control after laparoscopic surgeries, is conventionally achieved using analgesics such as non-steroidal anti-inflammatory drugs (NSAIDs and narcotics, but their administration has a lot of side effects. This study compares the efficacy and side effects of local anesthetic drugs versus conventional analgesics in post-operative pain control.Materials and Methods: This prospective investigation was conducted into two groups of patients (n=93. Group 1, as control group, was given conventional analgesics such as narcotics and NSAIDs. In investigational group, at the end of laparoscopic surgery, prior to port withdrawal, a local anesthetic mixture, a short acting (Lidocaine 2% plus a long acting (Bupivacaine 0.5% is instilled through the port lumen between the abdominal wall layers. The efficacy of both types of medications was compared to their efficacy and side effects.Results: 85% of the control group, received 5 to 20 ml Morphine for pain control while the others were controlled with trans-rectal NSAIDs. In the treatment group, the pain of 65% of the patients was controlled only by local anesthetic drugs, 30% required NSAIDs and the other 5% required narcotics administration for pain control.Conclusion: The administration of local anesthetic drugs after laparoscopic surgery is an effective method for pain control with a low complications rate and side effects of narcotics.

Laparoscopy is the most common procedure for correction of congenital pyloric stenosis. The standard laparoscopic approach is based on the three-port technique. In contrast to the standard laparoscopic technique, the single-incision laparoscopic surgery (SILS) requires only one incision. We report on our experience with this surgical approach. Between September 2009 and August 2010 a total of 24 children underwent a laparoscopic pyloromyotomy, 12 in SILS technique. The single incision was carried through the center of the umbilicus. The working instruments were introduced in a two-dimensional direction into the peritoneal cavity via the same umbilical incision. The two groups were compared for patients' demographics, operative report and early postoperative outcomes. All SILS procedures were performed successfully with no conversion rate. There were no differences in the preoperative parameters between the two groups regarding age before surgery and body weight at operation. Operative time and time of full enteral intake was similar to comparable procedures with usage of a standard laparoscopic approach. There were no operative or postoperative complications. The early experience described in this study confirms that SILS can be applied for treatment of pyloric stenosis with outcomes similar to the standard laparoscopic surgery.

Full Text Available Port site wound infection, abdominal wall hematoma and intraabdominal abscess formation has been reported after laparoscopic appendicectomy. We describe here a rectus sheath abscess which occurred three weeks after the laparoscopic appendicectomy. It was most likely the result of secondary infection of the rectus sheath hematoma due to bleeding into the rectus sheath from damage to the inferior epigastric arteries or a direct tear of the rectus muscle. As far as we are aware this complication has not been reported after laparoscopic appendicectomy.

Colorectal resections are common surgical procedures all over the world. Laparoscopic colorectal surgery is technically feasible in a considerable amount of patients under elective conditions. Several short-term benefits of the laparoscopic approach to colorectal resection (less pain, less morbidity, improved reconvalescence and better quality of life) have been proposed. This review compares laparoscopic and conventional colorectal resection with regards to possible benefits of the laparoscopic method in the short-term postoperative period (up to 3 months post surgery). We searched MEDLINE, EMBASE, CancerLit, and the Cochrane Central Register of Controlled Trials for the years 1991 to 2004. We also handsearched the following journals from 1991 to 2004: British Journal of Surgery, Archives of Surgery, Annals of Surgery, Surgery, World Journal of Surgery, Disease of Colon and Rectum, Surgical Endoscopy, International Journal of Colorectal Disease, Langenbeck's Archives of Surgery, Der Chirurg, Zentralblatt für Chirurgie, Aktuelle Chirurgie/Viszeralchirurgie. Handsearch of abstracts from the following society meetings from 1991 to 2004: American College of Surgeons, American Society of Colorectal Surgeons, Royal Society of Surgeons, British Assocation of Coloproctology, Surgical Association of Endoscopic Surgeons, European Association of Endoscopic Surgeons, Asian Society of Endoscopic Surgeons. All randomised-controlled trial were included regardless of the language of publication. No- or pseudorandomised trials as well as studies that followed patient's preferences towards one of the two interventions were excluded, but listed separately. RCT presented as only an abstract were excluded. Results were extracted from papers by three observers independently on a predefined data sheet. Disagreements were solved by discussion. 'REVMAN 4.2' was used for statistical analysis. Mean differences (95% confidence intervals) were used for analysing continuous variables. If

The nature of laparoscopic surgery makes it likely to benefit from current and future developments in virtual reality and telepresence technology. High-definition screens, three-dimensional sensory feedback and remote dextrous manipulation will be the next major developments in laparoscopic surgery. Simulators may be used in surgical training and in the evaluation of surgical capability.

Music education affects the mathematical and visuo-spatial skills of school-age children. Visuo-spatial abilities have a significant effect on laparoscopic suturing performance. We hypothesize that prior music experience influences the performance of laparoscopic suturing tasks. Thirty novices observed a laparoscopic suturing task video. Each performed 3 timed suturing task trials. Demographics were recorded. A repeated measures linear mixed model was used to examine the effects of prior music experience on suturing task time. Twelve women and 18 men completed the tasks. When adjusted for video game experience, participants who currently played an instrument performed significantly faster than those who did not (PMen who had never played an instrument or were currently playing an instrument performed better than women in the same group (P=0.002 and P<0.001). There was no sex difference in the performance of participants who had played an instrument in the past (P=0.29). This study attempted to investigate the effect of music experience on the laparoscopic suturing abilities of surgical novices. The visuo-spatial abilities used in laparoscopic suturing may be enhanced in those involved in playing an instrument.

Anesthesia related complications of laparoscopic cholecystectomy

International Nuclear Information System (INIS)

Qureshi, F.A.

2003-01-01

Objective: To determine the incidence of intraoperative anesthesia-related complications of laparoscopic cholecystectomy. Results: One hundred patients with male to female ratio of 1:8.09 in the age range of 20-80 years (mean 39 years) underwent general anesthesia for laparoscopic cholecystectomy. The duration of operation in 94 laparoscopic cholecystectomy was from 20 to 80 minutes (mean 60.63 minutes). The incidence of intraoperative hypotension was 9%. Four percent of the patients developed arrhythmias. Increase in end-tidal-carbon dioxide (ETCO/sub 2/) was observed in 3% of cases. Conversion rate to open cholecystectomy was 6%. Damage to intraabdominal vessels with trocar insertion occurred in 1% of cases. Conclusion: Although laparoscopic cholecystectomy has major surgical and anesthetic advantages, there are anesthesia related complications requiring specific anesthetic interventions to improve patients outcome without compromising their safety.

With the advent and rapid proliferation of laparoscopic cholecystectomy, numerous techniques and "tips" have been described. Intraoperative cholangiography during laparoscopic cholecystectomy can be tedious, frustrating, and time consuming. Described herein is a technique of intraoperative cholangiography during laparoscopic cholecystectomy which has proven to be easy, fast, and succinct. This method utilizes a rigid cholangiogram catheter which is placed into the peritoneal cavity through a small additional puncture site. This catheter is easily inserted into the cystic duct by extracorporeal manipulation. We suggest this method to surgeons who have shared our prior frustration with intraoperative cholangiography.

2017-01-01

Objectives: Benign paroxysmal positional vertigo is a common vestibular disorder and it may be idiopathic or secondary to some conditions such as surgery, but rare following laparoscopic surgery. Methods: We report two cases of benign paroxysmal positional vertigo secondary to laparoscopic surgery, one after laparoscopic cholecystectomy in a 51-year-old man and another following laparoscopic hysterectomy in a 60-year-old woman. Results: Both patients were treated successfully with manual or device-assisted canalith repositioning maneuvers, with no recurrence on the follow-up of 6 -18 months. Conclusions: Benign paroxysmal positional vertigo is a rare but possible complication of laparoscopic surgery. Both manual and device-assisted repositioning maneuvers are effective treatments for this condition, with good efficacy and prognosis. PMID:28255446

The Role of Laparoscopic-Assisted Myomectomy (LAM)

Science.gov (United States)

Nezhat, Ceana H.; Nezhat, Farr.; Nezhat, Camran

2001-01-01

Laparoscopic myomectomy has recently gained wide acceptance. However, this procedure remains technically highly demanding and concerns have been raised regarding the prolonged time of anesthesia, increased blood loss, and possibly a higher risk of postoperative adhesion formation. Laparoscopic-assisted myomectomy (LAM) is advocated as a technique that may lessen these concerns regarding laparoscopic myomectomy while retaining the benefits of laparoscopic surgery, namely, short hospital stay, lower costs, and rapid recovery. By decreasing the technical demands, and thereby the operative time, LAM may be more widely offered to patients. In carefully selected cases, LAM is a safe and efficient alternative to both laparoscopic myomectomy and myomectomy by laparotomy. These cases include patients with numerous large or deep intramural myomas. LAM allows easier repair of the uterus and rapid morcellation of the myomas. In women who desire a future pregnancy, LAM may be a better approach because it allows meticulous suturing of the uterine defect in layers and thereby eliminates excessive electrocoagulation.

Laparoscopic rectal cancer surgery: Where do we stand?

Large comparative studies and multiple prospective randomized control trials (RCTs) have reported equivalence in short and long-term outcomes between the open and laparoscopic approaches for the surgical treatment of colon cancer which has heralded widespread acceptance for laparoscopic resection of colon cancer.In contrast,laparoscopic total mesorectal excision (TME) for the treatment of rectal cancer has been welcomed with significantly less enthusiasm.While it is likely that patients with rectal cancer will experience the same benefits of early recovery and decreased postoperative pain from the laparoscopic approach,whether the same oncologic clearance,specifically an adequate TME can be obtained is of concern.The aim of the current study is to review the current level of evidence in the literature on laparoscopic rectal cancer surgery with regard to short-term and long-term oncologic outcomes.The data from 8 RCTs,3 metaanalyses,and 2 Cochrane Database of Systematic Reviews was reviewed.Current data suggests that laparoscopic rectal cancer resection may benefit patients with reduced blood loss,earlier retum of bowel function,and shorter hospital length of stay.Concerns that laparoscopic rectal cancer surgery compromises shortterm oncologic outcomes including number of lymph nodes retrieved and circumferential resection margin and jeopardizes long-term oncologic outcomes has not conclusively been refuted by the available literature.Laparoscopic rectal cancer resection is feasible but whether or not it compromises short-term or long-term results still needs to be further studied.

Laparoscopic common bile duct exploration (CBDE) is becoming more popular in the management of choledocholithiasis due to improved laparoscopic expertise and advancement in endoscopic technology and equipment. This study aimed to evaluate the safety and short-term outcome of laparoscopic CBDE in a single institution over a 3-year period. A retrospective review of the records of all patients who underwent laparoscopic CBDE in Tan Tock Seng Hospital between January 2006 and September 2008 was conducted. Fifty consecutive patients, with a median age of 60 years (range, 27 to 85) underwent laparoscopic CBDE for choledocholithiasis during the study period. About half of our patients presented as an emergency with acute cholangitis (32.0%) accounting for the majority. A total of 22 (44.0%) patients underwent laparoscopic CBDE as their primary procedure while the remaining 28 (56.0%) were subjected to preoperative ERCP initially. Of the latter group, documented stone clearance was only documented in 5 (17.9%) patients. Laparoscopic CBDE via the transcystic route was performed in 27 (54.0%) patients while another 18 patients (36.0%) had laparoscopic choledochotomy and 1 patient (2.0%) had laparoscopic choledocho-duodenostomy. There were 4 (8.0%) conversions in our series. The median operative time for laparoscopic CBDE via the transcystic route and the laparoscopic choledochotomy were 170 (75-465) and 250 (160-415) minutes, respectively. For the 18 patients who underwent a laparoscopic choledochotomy, T-tube was inserted in 8 (44.4%) patients while an internal biliary stent was placed in 4 (22.2%) with the remaining 6 patients (33.3%) undergoing primary closure of the choledochotomy. The median length of hospital stay was 2 days (range, 1 to 15) with no associated mortality. The main complications (n = 4, 8.0%) included retained CBD stones and biliary leakage. These were treated successfully with postoperative endoscopic retrograde cholangiopancreatography (ERCP) with

The management of gallbladder stones (lithiasis) concomitant with bile duct stones is controversial. The more frequent approach is a two-stage procedure, with endoscopic sphincterotomy and stone removal from the bile duct followed by laparoscopic cholecystectomy. The laparoscopic-endoscopic rendezvous combines the two techniques in a single-stage operation. To compare the benefits and harms of endoscopic sphincterotomy and stone removal followed by laparoscopic cholecystectomy (the single-stage rendezvous technique) versus preoperative endoscopic sphincterotomy followed by laparoscopic cholecystectomy (two stages) in people with gallbladder and common bile duct stones. We searched The Cochrane Hepato-Biliary Group Controlled Trials Register, CENTRAL, MEDLINE Ovid, Embase Ovid, Science Citation Index Expanded Web of Science, and two trials registers (February 2017). We included randomised clinical trials that enrolled people with concomitant gallbladder and common bile duct stones, regardless of clinical status or diagnostic work-up, and compared laparoscopic-endoscopic rendezvous versus preoperative endoscopic sphincterotomy procedures in people undergoing laparoscopic cholecystectomy. We excluded other endoscopic or surgical methods of intraoperative clearance of the bile duct, e.g. non-aided intraoperative endoscopic retrograde cholangiopancreatography or laparoscopic choledocholithotomy (surgical incision of the common bile duct for removal of bile duct stones). We used standard methodological procedures recommended by Cochrane. We included five randomised clinical trials with 517 participants (257 underwent a laparoscopic-endoscopic rendezvous technique versus 260 underwent a sequential approach), which fulfilled our inclusion criteria and provided data for analysis. Trial participants were scheduled for laparoscopic cholecystectomy because of suspected cholecysto-choledocholithiasis. Male/female ratio was 0.7; age of men and women ranged from 21 years to 87

We report our results and short term follow up of transperitoneal laparoscopic pyeloplasty for pelvi-ureteric junction (PUJ) obstruction. We have prospectively maintained a database to document our initial experience of 54 laparoscopic pyeloplasty. All procedures were carried out by one surgeon through a transperitoneal approach. The data extends from April 2005 to September 2008 and reports operative time, blood loss, complications, hospital stay, short term follow-up on symptomatic and radiological outcome. Fifty-four procedures were performed during the study period. Mean patient age was 29 years. Mean operating time was 133 minutes (range 65-300 minutes), and mean blood loss was 45 ml (range 20-300 ml). No intra operative complication occurred. Neither blood transfusion nor conversion to open surgery was required. Postoperative mean hospital stay was 3.4 days (range 3-14 days). There were 3 anastomotic leakages; 2 in the immediate postoperative period and 1 following removal of stent. They all required percutaneous drainage and prolonged stenting. Overall 47 (87%) patients have symptomatic relief and resolution of obstruction on renogram. Four (7%) patients developed recurrence. Three (5.5%) patients had symptomatic relief but have a persistent obstructive renogram. Laparoscopic pyeloplasty is an effective alternative treatment for symptomatic pelvi-ureteric junction obstruction. The results appear comparable to open pyeloplasty with decreased postoperative morbidity.

Reduced port laparoscopic surgery has recently emerged as a method to improve the cosmetic results of conventional laparoscopic surgery. We reported our technique of reduced port laparoscopic colectomy using 3-port and short-time outcomes. Between 2005 and 2012, we performed 161 reduced port laparoscopic colectomies using the 3-port technique. Data analyzed in-cluded age, gender, body mass index (BMI), duration of surgery, number of harvested lymph nodes, and duration of hospital stay. All of the cases were successfully performed using the 3-port procedure. The median durations of surgery and postoperative hospital stay were 140 mm (range 75-463 mm) and 9 days (range 5-38 days), respectively. No mortality was associated with this technique. Reduced port laparoscopic colectomy is feasible and may have advantages over conventional laparoscopic colectomy.

Laparoscopic cholecystectomy, a minimal access surgery, is fast replacing open cholecystectomy and is being associated with less trauma. The objective of this study was to compare the proinflammatory cytokine levels in both laparoscopic cholecystectomy and open cholecystectomy. This study was carried out at Aseer Central Hospital, Aseer region, Abha Private Hospital and the College of Medicine and Medical Sciences, King Khalid University, Abha, Kingdom of Saudi Arabia, during the time period October 1998 through to November 2000. Sixty-one patients were included in the study, 27 of them had laparoscopic cholecystectomy and 34 had open cholecystectomy. Cytokines [Interleukin-6 Interleukin-1b, Tumor necrosis factor -a and Interleukin- 8] were measured in blood samples collected from the patients before, at and 24 hours post surgery, using commercially available kits. Interleukin-6 levels were significantly increased at 24 hours post surgery in the open cholecystectomy group of patients compared to the laparoscopic cholecystectomy group (P<0.04). No differences were found in the other cytokines levels (Interleukin-1b, tumor necrosis factor -a and Interleukin-8) between the open cholecystectomy and laparoscopic cholecystectomy groups. Laparoscopic cholecystectomy, a minimal access surgery, is associated with lower levels of the proinflammatory interleukin-6 cytokine compared to open cholecystectomy. (author)

Communication is important for patient safety in the operating room (OR). Several studies have assessed OR communications qualitatively or have focused on communication in crisis situations. This study used prospective, quantitative observation based on well-established communication theory to assess similarities and differences in communication patterns between open and laparoscopic surgery. Based on communication theory, a standardized proforma was developed for assessment in the OR via real-time observation of communication types, their purpose, their content, and their initiators/recipients. Data were collected prospectively in real time in the OR for 20 open and 20 laparoscopic inguinal hernia repairs. Assessors were trained and calibrated, and their reliability was established statistically. During 1,884 min of operative time, 4,227 communications were observed and analyzed (2,043 laparoscopic vs 2,184 open communications). The mean operative duration (laparoscopic, 48 min vs open, 47 min), mean communication frequency (laparoscopic, 102 communications/procedure vs open, 109 communications/procedure), and mean communication rate (laparoscopic, 2.13 communications/min vs open, 2.23 communications/min) did not differ significantly across laparoscopic and open procedures. Communications were most likely to be initiated by surgeons (80-81 %), to be received by either other surgeons (46-50%) or OR nurses (38-40 %), to be associated with equipment/procedural issues (39-47 %), and to provide direction for the OR team (38-46%) in open and laparoscopic cases. Moreover, communications in laparoscopic cases were significantly more equipment related (laparoscopic, 47 % vs open, 39 %) and aimed significantly more at providing direction (laparoscopic, 46 % vs open, 38 %) and at consulting (laparoscopic, 17 % vs open, 12 %) than at sharing information (laparoscopic, 17 % vs open, 31 %) (P communications were found in both laparoscopic and open cases during a relatively low

2015-12-01

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.

This study aims to compare the early perioperative outcomes of robotic-assisted laparoscopic distal pancreatectomy (RDP) versus laparoscopic distal pancreatectomy (LDP). The clinicopathologic features of 45 consecutive patients who underwent minimally-invasive distal pancreatectomy from 2006 to 2015 were retrospectively reviewed. Thirty-nine patients who met our study criteria were included. Eight patients underwent RDP and 31 had LDP. There were 10 (25.6%) open conversions. Six (15.4%) patients had major (> grade 2) morbidities and there was no in-hospital mortality. There were 14 (35.9%) grade A and 9 (23.1%) grade B pancreatic fistulas. Comparison between RDP and LDP demonstrated no significant difference between the patients' baseline characteristics except there was increased frequency of spleen-preserving pancreatectomies (3 (37.5%) vs 25 (80.6%), P=0.016) and splenic-vessel preservation (5 (62.5%) vs 4 (12.9%), P=0.003) in RDP. Comparison between outcomes demonstrated that RDP was associated with a longer median operation time (452.5 (range, 300-685) vs 245 min (range, 85-430), P=0.001) and increased frequency of the procedure completed purely laparoscopically (8 (100%) vs 18 (58.1%), P=0.025). RDP can be safely adopted and is equivalent to LDP in most perioperative outcomes. It is also associated with a decreased frequency of the need for hand-assistance laparoscopic surgery or open conversion but needed a longer operation time. Copyright © 2016 John Wiley & Sons, Ltd.

Full Text Available Objectives: The most common indication for abdominal surgery in elderly (65 & older is gallstone disease.The elderly are more prone to complication of such surgery due to their other co-morbidity and thus they may benefit mostly from a safer method of surgical procedure. The purpose of this study was to evaluate the safety and outcome of laparoscopic cholecystectomy in elderly compare to the conventional method. Methods & Materials: Via prospective study from June 2005 to March 2008 included all patient older than 60 years of age who underwent cholecystectomy by open (Group A and laparoscopic (Group B method in Milad Hospital.The demographic data (sex age, American Society of Anesthesiologists’ (ASA score, postoperative mortality morbidity, length of stay and operative time were recorded for each patient and were compared between two methods. Data of patient’s analysis by SPSS with chi-square and t test. Results: The study included 311 elderlies (34% men and 66% women. Hundred fifty-seven patients underwent open cholecystectomy; 154 patients underwent laparoscopic cholecystectomy. The mean age was 7141 years. The outcome in group B (laparoscopic included: morality 0%, morbidity 2%, postoperative hospital stay 1 days, mean operation time was 40 minutes. In group A(open: mortality and morbidity rate were 21% and 12% respectively with postoperative hospital stay 331 days and similar operation time as group A. Conclusion: Laparoscopic cholecystectomy is the gold standard treatment and safe procedure in elderly patient and aging is not considered to be a contraindication laparoscopic surgery in such patients.

The patient was a 72-year-old man, who was referred to us at the beginning of July 2005 with a chief complaint of difficulty with swallowing. After a thorough medical examination, the patient was diagnosed with a penetrating ulcer due to reflux esophagitis, lower esophageal stricture, Barrett esophagus, and shortened esophagus. After administration of a proton pump inhibitor and 2 sessions of endoscopic dilatation, esophagitis was cured and the stricture was eliminated. Subsequently, Collis gastroplasty and Dor fundoplication, which seemed appropriate to certainly avoid injuring communication with the mediastinum created by the penetrating ulcer and provide radical cure, were performed laparoscopically. The patient made a good postoperative progress, was discharged on the 11th hospital day, and is now being followed up on an outpatient basis. There have been no signs of recurrence of esophagitis, and the penetrating ulcer was cured. To our knowledge, this is the first report of simultaneous laparoscopic Collis gastroplasty and Dor fundoplication in the English literature.

Colpohysterectomy is sometimes associated with a large upper colpectomy resulting in a shortened vagina, potentially impacting sexual function. We report on a preliminary experience of a laparoscopic colpoplasty to restore a normal vaginal length. Patients with shortened vaginas after a laparoscopic colpohysterectomy were considered for a laparoscopic modified Davydov's procedure to create a new vaginal vault using the peritoneum of the rectum and bladder. From 2010 to 2014, 8 patients were offered this procedure, after informed preoperative consent. Indications were 2 extensive recurrent vaginal intraepithelial neoplasias grade 3 and 6 radical hysterectomies for cervical cancer. Mean vaginal length before surgery was 3.8 cm (standard deviation, 1.6). Median operative time was 50 minutes (range, 45-90). Blood loss was minimal (50-100 mL). No perioperative complications occurred. Median vaginal length at discharge was 11.3 cm (range, 9-13). Sexual intercourse could be resumed around 10 weeks after surgery. At a median follow-up of 33.8 months (range, 2.4-51.3), 6 patients remained sexually active but 2 had stopped. Although this experience is small, this laparoscopic modified Davydov's procedure seems to be an effective procedure, adaptable to each patient's anatomy. If the initial postoperative regular self-dilatation is carefully observed, vaginal patency is durably restored and enables normal sexual function. Copyright © 2016 AAGL. Published by Elsevier Inc.

Full Text Available Nocardia brasiliensis is a rare human pathogen that is usually associated with localised cutaneous infections. We report a case of primary cutaneous Nocardia brasiliensis infection causing delayed wound healing that developed after ovarian cystectomy in an otherwise healthy 32-year-old woman. The patient was initially treated with cotrimoxazole, however due to intolerance intravenous amikacin was given and gradually the wound healed. The diagnosis was confirmed by demonstrating the causative organism in exudates, and cultures. Early diagnosis as well as early institution of chemotherapy is effective in most patients, and antimicrobial susceptibility testing of the isolate should be performed to identify the best treatment options.

Our present understanding of the effect of robotic surgery and surgical volume on the cost of radical prostatectomy (RP) is limited. Given the increasing pressures placed on healthcare resource utilization, such determinations of healthcare value are becoming increasingly important. Therefore, we performed a study to define the effect of robotic technology and surgical volume on the cost of RP. The state of Maryland mandates that all acute-care hospitals report encounter-level and hospital discharge data to the Health Service Cost Review Commission (HSCRC). The HSCRC was queried for men undergoing RP between 2008 and 2011 (the period during which robot-assisted laparoscopic radical prostatectomy [RALRP] was coded separately). High-volume hospitals were defined as >60 cases per year, and high-volume surgeons were defined as >40 cases per year. Multivariate regression analysis was performed to evaluate whether robotic technique and high surgical volume impacted the cost of RP. There were 1499 patients who underwent RALRP and 2565 who underwent radical retropubic prostatectomy (RRP) during the study period. The total cost for RALRP was higher than for RRP ($14,000 vs 10,100; Probotic surgery has come to dominate the healthcare marketplace, strategies to increase the role of high-volume providers may be needed to improve the cost-effectiveness of prostate cancer surgical therapy.

Perineal hernias are infrequent complications following abdominoperineal operations. Various approaches have been described for repair of perineal hernias including open transabdominal, transperineal or combined abdominoperineal repairs. The use of laparoscopic transabdominal repair of perineal hernias is not well-described. We present a case report demonstrating the benefits of laparoscopic repair of perineal hernia following previous laparoscopic abdominoperineal resection (APR) using a nonabsorbable mesh to repair the defect. We have demonstrated that the use of laparoscopy with repair of the pelvic floor defect using a non absorbable synthetic mesh offers an excellent alternative with many potential advantages over open transabdominal and transperineal repairs.

Full Text Available Central pancreatectomy is an ideal surgical procedure for the treatment of benign or low-grade malignant tumors in the pancreatic neck or the proximal body of the pancreas, and it can preserve more normal pancreatic tissue in order to reduce the incidence of endocrine and exocrine insufficiency after surgery. Although some clinical studies have demonstrated the feasibility and safety of this procedure, laparoscopic central pancreatectomy was technically challenging with a few number of cases. This article reviews the current status of laparoscopic central pancreatectomy and introduces our clinical experience of laparoscopic central pancreatectomy and pancreaticojejunostomy.

Since it's introduction, laparoscopic surgery represented a real revolution in clinical practice. The use of a new generation three-dimensional (3D) HD laparoscopic system can be considered a favorable "hybrid" made by combining two different elements: feasibility and diffusion of laparoscopy and improved quality of vision. In this study we report our clinical experience with use of three-dimensional (3D) HD vision system for laparoscopic surgery. Between 2013 and 2017 a prospective cohort study was conducted at the University Hospital of Palermo. We considered 163 patients underwent to laparoscopic three-dimensional (3D) HD surgery for various indications. This 3D-group was compared to a retrospective-prospective control group of patients who underwent the same surgical procedures. Considerating specific surgical procedures there is no significant difference in term of age and gender. The analysis of all the groups of diseases shows that the laparoscopic procedures performed with 3D technology have a shorter mean operative time than comparable 2D procedures when we consider surgery that require complex tasks. The use of 3D laparoscopic technology is an extraordinary innovation in clinical practice, but the instrumentation is still not widespread. Precisely for this reason the studies in literature are few and mainly limited to the evaluation of the surgical skills to the simulator. This study aims to evaluate the actual benefits of the 3D laparoscopic system integrating it in clinical practice. The three-dimensional view allows advanced performance in particular conditions, such as small and deep spaces and promotes performing complex surgical laparoscopic procedures.

Laparoscopic and endoscopic surgery rely uniquely on high quality display of acquired images, but a multitude of problems plague the researcher who attempts to reproduce such images for educational purposes. Some of these are intrinsic limitations of current laparoscopic/endoscopic visualization systems, while others are artifacts solely of the process used to acquire and reproduce such images. Whatever the genesis of these problems, a glance at current literature will reveal the extent to which endoscopy suffers from an inability to reproduce what the surgeon sees during a procedure. The major intrinsic limitation to the acquisition of high-quality still images from laparoscopic procedures lies in the inability to couple directly a camera to the laparoscope. While many systems have this capability, this is useful mostly for otolaryngologists, who do not maintain a sterile field around their scopes. For procedures in which a sterile field must be maintained, one trial method has been to use a beam splitter to send light both to the still camera and the digital video camera. This is no solution, however, since this results in low quality still images as well as a degradation of the image that the surgeon must use to operate, something no surgeon tolerates lightly. Researchers thus must currently rely on other methods for producing images from a laparoscopic procedure. Most manufacturers provide an optional slide or print maker that provides a hardcopy output from the processed composite video signal. The results achieved from such devices are marginal, to say the least. This leaves only one avenue for possible image production, the videotape record of an endoscopic or laparoscopic operation. Video frame grabbing is at least a problem to which industry has applied considerable time and effort to solving. Our own experience with computerized enhancement of videotape frames has been very promising. Computer enhancement allows the researcher to correct several of the

Laparoscopic distal gastrectomy has recently become accepted as a surgical option for early gastric cancer in the distal stomach, but laparoscopic total gastrectomy (LTG) has not become widespread because of technical difficulties of esophagojejunal anastomosis and splenic hilar lymphadenectomy. Splenic hilar lymphadenectomy should be employed in the treatment of advanced proximal gastric cancer to complete D2 dissection, but laparoscopically it is technically difficult even for skilled surgeons. Based on the evidence that prophylactic combined resection of spleen in total gastrectomy increased the risk of postoperative morbidity with no survival impact, surgeons have preferred laparoscopic spleen-preserving splenic hilar lymphadenectomy (LSPL) for advanced tumors without metastasis to splenic hilar nodes or invasion to the greater curvature of the stomach, and reports with LSPL have been increasing rather than LTG with splenectomy. In this paper, recent reports with laparoscopic splenic hilar lymphadenectomy were reviewed.

Full Text Available Context Pancreatic surgery is an extremely challenging field, and the management of pancreatic diseases continues to evolve. In the past decade, minimal access surgery is moving towards minimizing the surgical trauma by reducing numbers and size of the port. In the last few years, a novel technique with a single-incision laparoscopic approach has been described for several laparoscopic procedures. Objectives We present a single-port laparoscopic spleen-preserving distal pancreatectomy. To our knowledge, this is the first single-port pancreatic resection in Brazil and Latin America. Methods A 33-year-old woman with neuroendocrine tumor underwent spleen-preserving distal pancreatectomy via single-port approach. A single-incision advanced access platform with gelatin cap, self-retaining sleeve and wound protector was used. Results Operative time was 174 minutes. Blood loss was minimal, and the patient did not receive a transfusion. The recovery was uneventful, and the patient was discharged on postoperative day 4. Conclusions Single-port laparoscopic spleen-preserving distal pancreatectomy is feasible and can be safely performed in specialized centers by skilled laparoscopic surgeons.

Laparoscopic use of laser and monopolar electrocautery

Hunter, John G.

1991-07-01

Most general surgeons are familiar with monopolar electrocautery, but few are equally comfortable with laser dissection and coagulation. At courses across the country, surgeons are being introduced to laparoscopy and laser use in one and two day courses, and are certified from that day forward as laser laparoscopists. Some surgeons are told that laser and electrosurgery may be equally acceptable techniques for performance of laparoscopic surgery, but that a surgeon may double his patient volume by advertising 'laser laparoscopic cholecystectomy.' The sale of certain lasers has skyrocketed on the basis of such hype. The only surprise is that laparoscopic cholecystectomy complications occurring in this country seem to be more closely related to the laparoscopic access and visualization than to the choice of laser of electrocautery as the preferred instrument for thermal dissection. The purpose of this article is to: 1) Discuss the physics and tissue effects of electrosurgery and laser; 2) compare the design and safety of electrosurgical and laser delivery systems; and 3) present available data comparing laser and electrocautery application in laparoscopic cholecystectomy.

Laparoscopic subtotal colectomy (STC) is a complex procedure. It is possible that short-term benefits for segmental resections cannot be attributed to this complex procedure. This study aims to assess differences in short-term results for laparoscopic versus open STC during a 15-year single-institute experience. We reviewed consecutive patients undergoing laparoscopic or open elective or subacute STC from January 1997 to December 2012. Fifty-six laparoscopic and 50 open STCs were performed. The operation time was significantly longer in the laparoscopic group, median 266 min (range 121-420 min), compared to 153 min (range 90-408 min) in the open group (p < 0.001). Median hospital stay showed no statistical difference, 14 days (range 1-129 days) in the laparoscopic and 13 days (range 1-85 days) in the open group. Between-group postoperative complications were not statistically different. Laparoscopic STC has short-term results similar to the open procedure, except for a longer operation time. The laparoscopic approach for STC is therefore only advisable in selected patients combined with extensive preoperative counseling. Copyright © 2013 S. Karger AG, Basel.

OBJECTIVE To compare outcomes for laparoscopic ovariectomy (LapOVE) and laparoscopic-assisted ovariohysterectomy (LapOVH) in dogs. DESIGN Retrospective case series. ANIMALS 278 female dogs. PROCEDURES Medical records of female dogs that underwent laparoscopic sterilization between 2003 and 2013 were reviewed. History, signalment, results of physical examination, results of preoperative diagnostic testing, details of the surgical procedure, durations of anesthesia and surgery, intraoperative and immediate postoperative (ie, during hospitalization) complications, and short- (≤ 14 days after surgery) and long-term (> 14 days after surgery) outcomes were recorded. Data for patients undergoing LapOVE versus LapOVH were compared. RESULTS Intraoperative and immediate postoperative complications were infrequent, and incidence did not differ between groups. Duration of surgery for LapOVE was significantly less than that for LapOVH; however, potential confounders were not assessed. Surgical site infection was identified in 3 of 224 (1.3%) dogs. At the time of long-term follow-up, postoperative urinary incontinence was reported in 7 of 125 (5.6%) dogs that underwent LapOVE and 12 of 82 (14.6%) dogs that underwent LapOVH. None of the dogs had reportedly developed estrus or pyometra by the time of final follow-up. Overall, 205 of 207 (99%) owners were satisfied with the surgery, and 196 of 207 (95%) would consider laparoscopic sterilization for their dogs in the future. CONCLUSIONS AND CLINICAL RELEVANCE Results suggested that short- and long-term outcomes were similar for female dogs undergoing sterilization by means of LapOVE or LapOVH; however, surgery time may have been shorter for dogs that underwent LapOVE. Most owners were satisfied with the outcome of laparoscopic sterilization.

Laparoscopic total pancreatectomy is a complicated surgical procedure and rarely been reported. This study was conducted to investigate the safety and feasibility of laparoscopic total pancreatectomy. Three patients underwent laparoscopic total pancreatectomy between May 2014 and August 2015. We reviewed their general demographic data, perioperative details, and short-term outcomes. General morbidity was assessed using Clavien-Dindo classification and delayed gastric emptying (DGE) was evaluated by International Study Group of Pancreatic Surgery (ISGPS) definition. The indications for laparoscopic total pancreatectomy were intraductal papillary mucinous neoplasm (IPMN) (n = 2) and pancreatic neuroendocrine tumor (PNET) (n = 1). All patients underwent laparoscopic pylorus and spleen-preserving total pancreatectomy, the mean operative time was 490 minutes (range 450-540 minutes), the mean estimated blood loss was 266 mL (range 100-400 minutes); 2 patients suffered from postoperative complication. All the patients recovered uneventfully with conservative treatment and discharged with a mean hospital stay 18 days (range 8-24 days). The short-term (from 108 to 600 days) follow up demonstrated 3 patients had normal and consistent glycated hemoglobin (HbA1c) level with acceptable quality of life. Laparoscopic total pancreatectomy is feasible and safe in selected patients and pylorus and spleen preserving technique should be considered. Further prospective randomized studies are needed to obtain a comprehensive understanding the role of laparoscopic technique in total pancreatectomy.

Should all distal pancreatectomies be performed laparoscopically?

Despite the relatively slow start of laparoscopic pancreatectomy relative to other laparoscopic resections, an increasing number of these procedures are being performed around the world. Operations that were once considered impossible to perform laparoscopically, such as pancreaticoduodenectomy and central pancreatectomy are gaining momentum. Technology continues to improve, as does surgical experience and prowess. There are both enough experience and data (though retrospective) to confirm that LDP with or without spleen preservation appears to be a safe treatment for benign or noninvasive lesions of the pancreas. Based on the fact that LDP can be performed with similar or shorter operative times, blood loss, complication rates, and length of hospital stay than ODP, it can be recommended as the treatment of choice for benign and noninvasive lesions in experienced hands when clinically indicated. It is very difficult to make clear recommendations with regard to laparoscopic resection of malignant pancreatic tumors due to the lack of conclusive data. As long as margins are negative and lymph node clearance is within accepted standards, LDP appears to have no untoward oncologic effects on outcome. Certainly more data, preferably in the manner of a randomized clinical trial, are needed before additional recommendations can be made. Potential benefits of laparoscopic resection for cancer include the ability to inspect the abdomen and abort the procedure with minimal damage if occult metastases are identified. This does not delay the onset of palliative chemotherapy, which would be the primary treatment in that circumstance. In fact, there is evidence to suggest that there is a greater likelihood of receiving systemic therapy if a laparotomy is avoided in patients who have radiologically occult metastases. Patients may also undergo palliative laparoscopic gastric and biliary bypass if indicated. Faster wound healing may also translate into a shorter waiting time before

Rules and technical tricks in extremely difficult laparoscopic cholecystectomies

Full Text Available We remind you of some technical artifices required in order to resolve difficult cases, such as: antegrade laparoscopic cholecystectomy (LC, subtotal laparoscopic cholecystectomy (SLC and the “stairs” clipping of the cystic duct. Also we acknowledge the closing of the cystic duct. We analyzed the medical records of 15251 laparoscopic cholecystectomies performed during 1994-2015, with emphasis on: surgical technique, conversion rate, hemorrhage, postoperative bile leaking, iatrogenic MBD injuries and mortality. We divided the cases in 5 study groups, group 1 (1994- 2004 N= 5138, group 2 (2005-2015 N= 10113, group 3 (fundus first cholecystectomies, N=2348, group 4 (retrograde cholecystectomies, N=12889 and group 5 (subtotal laparoscopic cholecystectomy-SLC, N=14 which we compared regarding the main parameters. We prefer to perform a “step by step” clipping each time the length of the clip does not cover all the circumference of the cystic duct. This artifices, is a simple laparoscopic gesture easy to perform and has the advantage of avoiding a large excessive and risky laparoscopic dissection in the vicinity of the main biliary duct. More seldom we appeal to the suture of the cystic stump using the intracorporeal knots or a simple stump ligation with an extracorporeal preformed not. We did not encounter any late or early complications following the implementation of this technical laparoscopic artifice. Laborious laparoscopic cholecystectomies performed by a well-trained surgical team ensure the premises of a good performance even while adopting laparoscopic ingenious and difficile gestures that also respect the intraoperatory rules and principals.

Full Text Available Gossypiboma is defined as a mass caused by foreign body reaction developed around the retained surgical item in the operative area. When diagnosed, it should be removed in symptomatic patients. Minimal invasive surgery should be planned for the removal of the retained item. The number of cases treated by laparoscopic approach is rare in the literature. We present a case of forty-year-old woman referred to emergency room with acute abdomen diagnosed as gossypiboma and treated successfully with laparoscopic surgery.

Spleen injury appears in 10% to 30% of abdominal trauma patients. Mortality among the patients in the last 20 years remains high (6% to 7%) and shows no tendency to decline. Nowadays nonoperative management is widely accepted management of patients with low-grade spleen injury, whereas management of patients with high-grade spleen injury (III and higher) is not so obvious. There are 3 methods exist in treatment of such patients: conservative (with or without angioembolization), spleen-preserving operations, and splenectomy. Today laparoscopic splenectomy is not a widely used operation and only few studies reported about successful use of laparoscopic splenectomy in patients with spleen injury.The aim of the study was to determine indications and contraindications for laparoscopic splenectomy in abdominal trauma patients and to analyze results of the operations. The study involved 42 patients with spleen injury grade III who were admitted in our institute in the years of 2010 to 2014. The patients were divided in 2 groups. Laparoscopic splenectomy was performed in 23 patients (group I) and "traditional" splenectomy was carried out in 19 patients (group II). There was no difference in the demographic data and trauma severity between the 2 groups. Noninvasive investigations, such as laboratory investigations, serial abdominal ultrasound examinations, x-ray in multiple views, and computed tomography had been performed before the decision about necessity of an operation was made. Patients after laparoscopic operations had better recovering conditions compared with patients with the same injury after "traditional" splenectomy. Neither surgery-related complications nor mortalities were registered in both groups. Laparoscopic splenectomy was more time-consuming operation than "traditional" splenectomy. We suggest that as experience of laparoscopic splenectomy is gained the operation time will be reduced. Laparoscopic splenectomy is a safe feasible operation in patients

PRINCIPLES OF SAFETY IN LAPAROSCOPIC CHOLECYSTECTOMY

Full Text Available Background. After more than decade of routine use of laparoscopic cholecystectomy for treatment of symptomatic gallbladder stones, the incidence of biliary injuries, which are potentially life threatening and cause prolonged hospitalization and major morbidity, seems to be increased in laparoscopic cholecystectomy compared with open operation. Injury rate was from some reports 2.5 to 4 times higher than with open operation. There are many proposed classifications of types of biliary injuries.The most frequent direct causes of laparoscopic biliary injury are misidentification of the common bile duct, cautery injuries to the bile duct and improper application of clips to the cystic duct.Conclusions. To avoid misidentification of ducts one should conclusively identify cystic duct and artery, the structures to be divide, in every laparoscopic cholecystectomy. To achieve that goal, Calot’s triangle must be dissected free of fat and fibrous – tissue and the lower end of the gallbladder must be dissected of the liver bed. The only two structures entering the gallbladder should be visible – cystic duct and artery. With avoidance of blind application of cautery and clips to control bleeding one should avoid injury of bile duct. Low cautery settings should be used in portal dissections to prevent arc.With meticulous care in dissection and conclusive identification of cystic duct and artery we can prevent injuries of bile duct, which still have impermissible high incidence. In the article 504 laparoscopic cholecystectomies performed at the Department of abdominal surgery in BPD in 2002 were analysed. We follow priciples of safety in laparoscopic cholecystectomy. There were no biliary injuries reports.

OBJECTIVE: To investigate the frequency and severity of dysphagia during the first 8 weeks after laparoscopic Nissen fundoplication for gastro-oesophageal reflux disease. So far, there have been no studies reporting data on day-to-day occurrence of dysphagia after laparoscopic fundoplication...... in a consecutive series of patients. This may explain why the frequency of dysphagia varies greatly in the literature (4-100%). MATERIAL AND METHODS: Forty consecutive patients, undergoing elective laparoscopic Nissen fundoplication, completed a standard dysphagia registration diary each day during the first 8...... weeks after surgery. Patients who preoperatively had suffered from dysphagia were excluded. Thus, none of the patients had dysphagia in the 2-month period before surgery. Ten patients undergoing elective cholecystectomy served as controls. Data were quantified, and a score value of 4 or more...

The treatment of hepatocellular carcinoma (HCC) is complicated and challenging because of the frequent presence of cirrhosis. Therefore, we propose a novel surgical approach to minimize the invasiveness and risk in patients with HCC, hypersplenism, and esophagogastric varices. This was a retrospective study carried out in 25 patients with HCC and hypersplenism and who underwent simultaneous laparoscopic-guided radio-frequency ablation and laparoscopic splenectomy with endoscopic variceal ligation. Tumor size was restricted to a single nodule of splenectomy. Laparoscopic-guided radio-frequency ablation with laparoscopic splenectomy and endoscopic variceal ligation could be an available technique for patients with HCC <3 cm, hypersplenism, and esophagogastric varices. This approach may help to minimize the surgical risks and results in a fast increase in platelet counts with an acceptable rate of complications.

Objectives: Surgical appraisal and revalidation are key components of good surgical practice and training. Assessing technical skills in a structured manner is still not widely used. Laparoscopic surgery also requires the surgeon to be competent in technological aspects of the operation. Methods: Checklists for generic, specific technical, and technological skills for laparoscopic cholecystectomies were constructed. Two surgeons with >12 years postgraduate surgical experience assessed each operation blindly and independently on DVD. The technological skills were assessed in the operating room. Results: One hundred operations were analyzed. Eight trainees and 10 consultant surgeons were recruited. No adverse events occurred due to technical or technological skills. Mean interrater reliability was kappa=0.88, P=technical and technological skills between trainee and consultant surgeons were significant, Mann-Whitney P=technical and technological skills can be measured to assess performance of laparoscopic surgeons. This technical and technological assessment tool for laparoscopic surgery seems to have face, content, concurrent, and construct validities and could be modified and applied to any laparoscopic operation. The tool has the possibility of being used in surgical training and appraisal. We aim to modify and apply this tool to advanced laparoscopic operations. PMID:17212881

Validating a Local Failure Risk Stratification for Use in Prospective Studies of Adjuvant Radiation Therapy for Bladder Cancer

Baumann, Brian C.; He, Jiwei; Hwang, Wei-Ting; Tucker, Kai N.; Bekelman, Justin E.; Herr, Harry W.; Lerner, Seth P.; Guzzo, Thomas J.; Malkowicz, S. Bruce; Christodouleas, John P.

2016-01-01

Purpose: To inform prospective trials of adjuvant radiation therapy (adj-RT) for bladder cancer after radical cystectomy, a locoregional failure (LF) risk stratification was proposed. This stratification was developed and validated using surgical databases that may not reflect the outcomes expected in prospective trials. Our purpose was to assess sources of bias that may affect the stratification model's validity or alter the LF risk estimates for each subgroup: time bias due to evolving surgical techniques; trial accrual bias due to inclusion of patients who would be ineligible for adj-RT trials because of early disease progression, death, or loss to follow-up shortly after cystectomy; bias due to different statistical methods to estimate LF; and subgrouping bias due to different definitions of the LF subgroups. Methods and Materials: The LF risk stratification was developed using a single-institution cohort (n=442, 1990-2008) and the multi-institutional SWOG 8710 cohort (n=264, 1987-1998) treated with radical cystectomy with or without chemotherapy. We evaluated the sensitivity of the stratification to sources of bias using Fine-Gray regression and Kaplan-Meier analyses. Results: Year of radical cystectomy was not associated with LF risk on univariate or multivariate analysis after controlling for risk group. By use of more stringent inclusion criteria, 26 SWOG patients (10%) and 60 patients from the single-institution cohort (14%) were excluded. Analysis of the remaining patients confirmed 3 subgroups with significantly different LF risks with 3-year rates of 7%, 17%, and 36%, respectively (P<.01), nearly identical to the rates without correcting for trial accrual bias. Kaplan-Meier techniques estimated higher subgroup LF rates than competing risk analysis. The subgroup definitions used in the NRG-GU001 adj-RT trial were validated. Conclusions: These sources of bias did not invalidate the LF risk stratification or substantially change the model's LF estimates.

Invasive bladder cancer: treatment strategies using transurethral surgery, chemotherapy and radiation therapy with selection for bladder conservation

Shipley, William U.; Zietman, Anthony L.; Kaufman, Donald S.; Althausen, Alex F.; Heney, Niall M.

1997-01-01

Purpose: Combined modality therapy has become the standard oncologic approach to achieve organ preservation in many malignancies. Methods and Materials: Although radical cystectomy has been considered as standard treatment for invasive bladder carcinoma in the United States, good results have been recently reported from several centers using multimodality treatment, particularly in patients with clinical T2 and T3a disease who do not have a ureter obstructed by tumor. Results: The components of the combined treatment are usually transurethral resection of the bladder tumor (TURBT) followed by concurrent chemotherapy and radiation therapy. Following an induction course of therapy a histologic response is evaluated by cystoscopy and rebiopsy. Clinical 'complete responders' (tumor site rebiopsy negative and urine cytology with no tumor cells present) continue with a consolidation course of concurrent chemotherapy and radiation. Those patients not achieving a clinical complete response are recommended to have an immediate cystectomy. Individually the local monotherapies of radiation, TURBT, or multidrug chemotherapy each achieve a local control rate of the primary tumor of from 20 to 40%. When these are combined, clinical complete response rates of from 65 to 80% can be achieved. Seventy-five to 85% of the clinical complete responders will remain with bladders free of recurrence of an invasive tumor. Conclusions: Bladder conservation trials using combined modality treatment approaches with selection for organ conservation by response of the tumor to initial treatment report overall 5-year survival rates of approximately 50%, and a 40-45% 5-year survival rate with the bladder intact. These modern multimodality bladder conservation approaches offer survival rates similar to radical cystectomy for patients of similar clinical stage and age. Bladder-conserving therapy should be offered to patients with invasive bladder carcinoma as a realistic alternative to radical

2006-03-01

Full Text Available Abstract Background Laparoscopy has became as the preferred surgical approach to a number of different diseases because it allows a correct diagnosis and treatment at the same time. In abdominal emergencies, both components of treatment – exploration to identify the causative pathology and performance of an appropriate operation – can often be accomplished via laparoscopy. There is still a debate of peritonitis as a contraindication to this kind of approach. Aim of the present work is to illustrate retrospectively the results of a case-control experience of laparoscopic vs. open surgery for abdominal peritonitis emergencies carried out at our institution. Methods From January 1992 and January 2002 a total of 935 patients (mean age 42.3 ± 17.2 years underwent emergent and/or urgent surgery. Among them, 602 (64.3% were operated on laparoscopically (of whom 112 -18.7% – with peritonitis, according to the presence of a surgical team trained in laparoscopy. Patients with a history of malignancy, more than two previous major abdominal surgeries or massive bowel distension were not treated Laparoscopically. Peritonitis was not considered contraindication to Laparoscopy. Results The conversion rate was 23.2% in patients with peritonitis and was mainly due to the presence of dense intra-abdominal adhesions. Major complications ranged as high as 5.3% with a postoperative mortality of 1.7%. A definitive diagnosis was accomplished in 85.7% (96 pat. of cases, and 90.6% (87 of these patients were treated successfully by Laparoscopy. Conclusion Even if limited by its retrospective feature, the present experience let us to consider the Laparoscopic approach to abdominal peritonitis emergencies a safe and effective as conventional surgery, with a higher diagnostic yield and allows for lesser trauma and a more rapid postoperative recovery. Such features make Laparoscopy a challenging alternative to open surgery in the management algorithm for abdominal

Open appendicectomy is the traditional standard treatment for appendicitis. Laparoscopic appendicectomy is perceived as a procedure with greater potential for complications and longer operative times. This paper examines the hypothesis that unsupervised laparoscopic appendicectomy by surgical trainees is a safe and time-effective valid alternative. Medical records, operating theatre records and histopathology reports of all patients undergoing laparoscopic and open appendicectomy over a 15-month period in two hospitals within an area health service were retrospectively reviewed. Data were analysed to compare patient features, pathology findings, operative times, complications, readmissions and mortality between laparoscopic and open groups and between unsupervised surgical trainee operators versus consultant surgeon operators. A total of 143 laparoscopic and 222 open appendicectomies were reviewed. Unsupervised trainees performed 64% of the laparoscopic appendicectomies and 55% of the open appendicectomies. There were no significant differences in complication rates, readmissions, mortality and length of stay between laparoscopic and open appendicectomy groups or between trainee and consultant surgeon operators. Conversion rates (laparoscopic to open approach) were similar for trainees and consultants. Unsupervised senior surgical trainees did not take significantly longer to perform laparoscopic appendicectomy when compared to unsupervised trainee-performed open appendicectomy. Unsupervised laparoscopic appendicectomy by surgical trainees is safe and time-effective.

Biologic scaffolds composed of extracellular matrix (ECM) have been used to facilitate the constructive remodeling of several tissue types. Previous studies suggest that the ECM scaffold remodeling process is dependent on microenvironmental factors, including tissue-specific biomechanical loading. The objective of the present study was to evaluate the effects of long-term catheterization (LTC), with its associated inhibition of bladder filling and physiologic biomechanical loading, on ECM scaffold remodeling following partial cystectomy in a canine model. Reconstruction of the partial cystectomy site was performed using ECM scaffolds prepared from porcine small intestinal submucosa (SIS) or porcine urinary bladder matrix (UBM). Animals were randomly assigned to either a long-term catheterization (LTC) group (n=5, catheterized 28 d) or a short-term catheterization group (STC, n=5, catheterized 24 h), and scaffold remodeling was assessed by histologic methods at 4 and 12 wk postoperatively. By 4 wk, animals in the STC group showed a well-developed and highly differentiated urothelium, a robust vascularization network, abundant smooth muscle actin (SMA), and smooth muscle myosin heavy chain (smMHC) expressing spindle-shaped cells, and many neuronal processes associated with newly formed arterioles. In contrast, at 4 wk the scaffolds in LTC animals were not epithelialized, and did not express neuronal markers. The scaffolds in the LTC group developed a dense granulation tissue containing SMA+, smMHC-, spindle-shaped cells that were morphologically and phenotypically consistent with myofibroblasts, but not smooth muscle cells. By 12 wk postoperatively, the ECM scaffolds in the STC animals showed a constructive remodeling response, with a differentiated urothelium and islands of smooth muscle cells within the remodeled scaffold. In contrast, at 12 wk the scaffolds in LTC animals had a remodeling response more consistent with fibrosis even though catheters had been

Standardized short courses in laparoscopic cholecystectomy aim to teach laparoscopic skills to surgical trainees, although end-of-course assessments of performance remain subjective. The current study aims to objectively assess psychomotor skills acquisition of trainees attending laparoscopic cholecystectomy courses. Thirty-seven junior surgical trainees had their laparoscopic skills assessed before and after attending 1 of 3 separate 2-day courses (A, B, and C), all with identical format. Assessments were comprised of a standardized simulated laparoscopic task, with performance measured using a valid electromagnetic hand-motion tracking device. Overall, trainees made significant improvements in path length (P=.006), number of movements (Ppsychomotor skills on courses. In addition to providing participants with an insight into their skills, these data can be used to demonstrate course efficacy.

Video games are mainly considered to be of entertainment value in our society. Laparoscopic surgery and video games are activities similarly requiring eye-hand and visual-spatial skills. Previous studies have not conclusively shown a positive correlation between video game experience and improved ability to accomplish visual-spatial tasks in laparoscopic surgery. This study was an attempt to investigate this relationship. The aim of the study was to investigate whether previous video gaming experience affects the baseline performance on a laparoscopic simulator trainer. Newly qualified medical officers with minimal experience in laparoscopic surgery were invited to participate in the study and assigned to the following groups: gamers (n = 20) and non-gamers (n = 20). Analysis included participants' demographic data and baseline video gaming experience. Laparoscopic skills were assessed using a laparoscopic simulator trainer. There were no significant demographic differences between the two groups. Each participant performed three laparoscopic tasks and mean scores between the two groups were compared. The gamer group had statistically significant better results in maintaining the laparoscopic camera horizon ± 15° (p value = 0.009), in the complex ball manipulation accuracy rates (p value = 0.024) and completed the complex laparoscopic simulator task in a significantly shorter time period (p value = 0.001). Although prior video gaming experience correlated with better results, there were no significant differences for camera accuracy rates (p value = 0.074) and in a two-handed laparoscopic exercise task accuracy rates (p value = 0.092). The results show that previous video-gaming experience improved the baseline performance in laparoscopic simulator skills. Copyright © 2017 IJS Publishing Group Ltd. Published by Elsevier Ltd.

Pelvic lymph node dissection (PLND) in prostate cancer is the most effective method for detecting lymph node metastases. However, a decline in the rate of PLND during radical prostatectomy (RP) has been noted. This is likely the result of prostate cancer stage migration in the prostate-specific antigen-screening era, and the introduction of minimally invasive approaches such as robot-assisted radical prostatectomy (RARP). To assess the efficacy, limitations, and complications of PLND during RARP. A review of the literature was performed using the Medline, Scopus, and Web of Science databases with no restriction of language from January 1990 to December 2012. The literature search used the following terms: prostate cancer, radical prostatectomy, robot-assisted, and lymph node dissection. The median value of nodal yield at PLND during RARP ranged from 3 to 24 nodes. As seen in open and laparoscopic RP series, the lymph node positivity rate increased with the extent of dissection during RARP. Overall, PLND-only related complications are rare. The most frequent complication after PLND is symptomatic pelvic lymphocele, with occurrence ranging from 0% to 8% of cases. The rate of PLND-associated grade 3-4 complications ranged from 0% to 5%. PLND is associated with increased operative time. Available data suggest equivalence of PLND between RARP and other surgical approaches in terms of nodal yield, node positivity, and intraoperative and postoperative complications. PLND during RARP can be performed effectively and safely. The overall number of nodes removed, the likelihood of node positivity, and the types and rates of complications of PLND are similar to pure laparoscopic and open retropubic procedures.

Since its introduction in the early 1990s, the laparoscopic cholecystectomy has become the standard surgical intervention for cholelithiasis. The laparoscopic technique is being used in an increasing number of abdominal procedures. Intestinal volvulus is a rare complication of laparoscopic procedures, such as the laparoscopic cholecystectomy. A review of the literature revealed 12 reports of this complication occurring without a clear cause. Etiologic factors that have been postulated include congenital malrotation, previous surgery, and intraoperative factors, such as pneumoperitoneum, mobilization of the bowel, and patient position. In this paper, we review the literature for this rare complication and report on a case of cecal bascule (a type of cecal volvulus) occurring following the laparoscopic cholecystectomy. Of the 12 prior reports of intestinal volvulus following laparoscopic procedures, 8 of these followed the laparoscopic cholecystectomy, of which two were cecal volvulae. This is the first reported case of a cecal bascule occurring following the laparoscopic cholecystectomy.

the middle colic vein (MCV) are relatively difficult. With the SMV and pancreas as anatomic landmarks, it is more feasible to locate the blood vessels in the neck of the pancreas. The middle colic artery (MCA) originates from the superior mesenteric artery (SMA), and the distance from the inferior border of the pancreas differs slightly in the literature, but is at the most 5 cm. Identification of the MCA trunk and branches, as well as the common origin of the MCA and RCA, is of great importance for the maintaining the blood supply during surgery for primary colon cancer. The MCV mainly drains into the SMV and GCT; however, if branching variation drains into the jejunal vein, inferior mesenteric vein, or splenic vein, the effect is serious when a vessel is torn. Isolation of the GCT is the step at which bleeding will likely occur in standard right resection and is a difficult stage of the surgery. The GCT has five origins including the right gastroepiploic vein (RGV), right colic vein (RCV), accessory right colic vein (ARCV), pancreaticduodenal vein (PDV), and MCV, which can have 2, 3, or 4 branches; therefore, familiarity with variants may be helpful to avoid bleeding. Approximately 5-10% of colon cancers at the hepatic flexure have No. 6 group lymph node metastasis, and laparoscopic radical extended right hemicolectomy requires thorough dissection of No. 6 group lymph nodes and the omental arcade 10 cm from the pylorus. The inferior arteriovenous vessels are a common source of bleeding, and the RGV can serve as a clue to finding the artery. The core area of laparoscopic radical extended right hemicolectomy includes the pancreatic neck, duodenum, and right gastroepiploic vessels. The difficulty lies with the standard treatment of the GCT. A medial-to-lateral approach is more in line with the principle of no-touch in tumor surgery and is applied from lower to upper, inside to outside, and left to right, for both the vessels and plane of dissection.

Training in laparoscopic surgery is important not only to acquire and improve skills but also avoid the loss of acquired abilities. The aim of this single-centre, prospective randomized study was to assess skill acquisition of different laparoscopic techniques and identify the point in time when acquired skills deteriorate and training is needed to maintain these skills. Sixty surgical novices underwent laparoscopic surgery (LS) and single-incision laparoscopic surgery (SILS) baseline training (BT) performing two validated tasks (peg transfer, precision cutting). The novices were randomized into three groups and skills retention testing (RT) followed after 8 (group A), 10 (group B) or 12 (group C) weeks accordingly. Task performance was measured in time with time penalties for insufficient task completion. 92 % of the participants completed the BT and managed to complete the task in the required time frame of proficiency. Univariate and multivariate analyses revealed that SILS (P skills (comparison of BT vs RT) was not identified; however, for SILS a significant deterioration of skills (adjustment of BT and RT values) was demonstrated for all groups (A-C) (P skills more difficult to maintain. Acquired LS skills were maintained for the whole observation period of 12 weeks but SILS skills had begun to deteriorate at 8 weeks. These data show that maintenance of LS and SILS skills is divergent and training curricula need to take these specifics into account.

Piaggio, Lisandro A; González, Ricardo

We describe the feasibility and short-term results of laparoscopic transureteroureterostomy in children. We performed transperitoneal laparoscopic transureteroureterostomy with a 4-trocar technique in 3 children with a mean age of 63 months (range 18 to 105). Diagnoses were unilateral ureteral obstruction after cross-trigonal reimplantation for vesicoureteral reflux (1 patient), unilateral refluxing megaureter (1) and ureteral injury after bladder diverticulectomy (1). Cystoscopy, retrograde pyelogram and stent placement in the recipient ureter were performed at the beginning of each case. The anastomoses were carried out with running 6-zero reabsorbable sutures at the level of the pelvic bream. An abdominal drain and Foley catheter were left indwelling for 1 to 3 days. All cases were performed successfully. Postoperative course was uneventful except for a transient urinary leak, and patients were discharged home on postoperative day 2 to 4. At a mean followup of 6 months all patients were clinically well, with normal kidney function and blood pressure, and no significant hydronephrosis. Based on our initial experience, laparoscopic transureteroureterostomy is safe and effective, and is associated with little blood loss, minimal analgesia requirements, fast recovery and excellent cosmetic results. We believe that in selected cases in which transureteroureterostomy is the chosen technique a laparoscopic approach is advantageous.

Bladder cancer: The combination of chemotherapy and irradiation in the treatment of patients with muscle-invading tumors

In the USA the recommended treatment for patients with muscle-invading transitional cell cancer of the bladder is usually radical cystectomy. Conservative surgery irradiation, and cisplatin-based systemic chemotherapy are, however, each effective for some patients. Although they provide the opportunity for bladder preservation, each modality, when used alone, is inferior to radical cystectomy in terms of local control and, perhaps, survival. Many recent publications have now documented the efficacy of combined modality treatment protocols employing all three of these modalities together. All employ a selective approach in which the patients only receive full-dose radiation if they have had a complete response to induction CMT. Overall survival data for T2-T3a patients are certainly as good as any reported cystectomy series of similarly clinically staged and similar aged patients. Radiation adds very significantly to the transurethral resection and systemic chemotherapy to maintain the bladder free of tumor. Substantially higher rates of pathologic confirmation of complete response are found following transurethral surgery and chemoradiation when compared with transurethral surgery and chemotherapy omitting the radiation. Overall survival is as good as cystectomy based approaches at 48-54% and over 80% of these long-term survivors keep their bladders. Following such therapies, 20-30% will subsequently develop superficial tumors. These patients may still be well treated by standard methods using transurethral resection and intravesical drugs. The concern of urologists that the conserved irradiated bladder functions poorly has also been answered by recent reports using modern radiation techniques. The instance of cystectomy for bladder shrinkage is repeatedly below 2%. Furthermore, sexual function is commonly preserved. The systemic morbidity of the chemotherapy is relatively high, but new approached using anti-emetics and GCSF now allow this to be reduced. In many

Laparoscopic intestinal derotation: original technique.

The intestinal derotation technique, introduced by Cattel and Valdoni 40 years ago, is carried out using a laparoscopic procedure, which is described here for the first time. The method is effective in the treatment of malign lesions of the III and IV duodenum and during laparoscopic subtotal colectomy with anastomosis between the ascending colon and the rectum. Ultimately, the procedure allows for the verticalization of the duodenal C and the anterior positioning of the mesenteric vessels, facilitating biopsy and resection of the III and IV duodenal portions and allowing anastomosis of the ascending rectum, avoiding both subtotal colectomy and the risk of torsion of the right colic loop. Although the procedure calls for extensive experience with advanced video-laparoscopic surgery, it is both feasible and repeatable. In our experience we have observed no mortality or morbidity.

Achalasia is characterized by an incomplete relaxation of the lower esophageal sphincter. The best treatment is surgical and the laparoscopic approach may have good results. To assess the results of laparoscopic Heller myotomy among patients with achalasia. Prospective study of patients subjected to a laparoscopic Heller myotomy between 1995 and 2004. Clinical features, early and late operative results were assessed. Twenty seven patients aged 12 to 74 years (12 females) were operated. All had disphagia lasting for a mean of 32 months. Mean lower esophageal sphincter pressure ranged from 18 to 85 mmHg. Eight patients received other treatments prior to surgery but symptoms persisted or reappeared. The preoperative clinical score was 7. No patient died and no procedure had to be converted to open surgery. In a follow up of 21 to 131 months, all patients are satisfied with the surgical results and the postoperative clinical score is 1. Only one patient with a mega esophagus maintained a clinical score of six. In this series of patients, laparoscopic Heller myotomy was an effective and safe treatment for esophageal achalasia.

Full Text Available Laparoscopic fundoplication is fast emerging as the treatment of choice of gastro-esophageal reflux disease. However, a complication peculiar to laparoscopic surgery for this disease is the intrathoracic migration of the wrap. This article describes a case of a male patient who developed this particular complication after laparoscopic total fundoplication. Following a trauma, wrap migration occurred. The typical history and symptomatology is described. The classical Barium swallow picture is enclosed. Laparoscopic redo fundoplication was carried out. The difficulties encountered are described. Postoperative wrap migration can be suspected clinically by the presence of a precipitating event and typical symptomatology. Confirmation is by a Barium swallow. Treatment is by redo surgery.

For patients with recurrent inguinal hernia, or bilateral inguinal hernia, or for women, laparoscopic repair offers significant advantages over open techniques with regard to recurrence risk, pain, and recovery. For unilateral first-time hernias, either laparoscopic or open repair with mesh can offer excellent results.

Although the feasibility and safety of laparoscopic surgery for transverse colon cancer have been shown by the recent studies, the optimal laparoscopic approach for mid-transverse colon cancer is controversial. We retrospectively analyzed the data of patients with the mid-transverse colon cancer at our institutions between January 2007 and April 2017. Thirty-eight and 34 patients who received extended right hemicolectomy and transverse colectomy, respectively, were enrolled. There were no significant differences in operating time, blood loss, and hospital stay between the two groups. Postoperative complications developed in 10 of 34 patients (29.4%; wound infection: 2 cases, anastomotic leakage: 2 cases, bowel obstruction: 1 case, incisional hernia: 2 cases, others: 3 cases) for the transverse colectomy group and in 4 of 38 patients (10.5%; wound infection: 1 case, anastomotic leakage: 0 case, bowel obstruction: 2 cases, incisional hernia: 0 case, others: 1 case) for the extended right hemicolectomy group (P = 0.014). Although the median number of harvested #221 and #222 LNs was similar between the two groups (6 vs. 8, P = 0.710, and 3 vs. 2, P = 0.256, respectively), that of #223 was significantly larger in extended right hemicolectomy than in transverse colectomy (3 vs. 1, P = 0.038). The 5-year disease-free and overall survival rates were 92.4 and 90.3% for the extended right hemicolectomy group, and 95.7 and 79.6% for the transverse colectomy group (P = 0.593 and P = 0.638, respectively). Laparoscopic extended right hemicolectomy and laparoscopic transverse colectomy offer similar oncological outcomes for mid-transverse colon cancer. Laparoscopic extended right hemicolectomy might be associated with fewer postoperative complications.

Laparoscopic repairs for perforated peptic ulcer (PPU) are likely to fail in patients with shock, gastric outlet obstruction, or large perforations. This prospective study was performed to evaluate a revised approach of laparoscopic repair with endoscopic assistance to treat these patients. Between April 2001 and February 2002, 30 consecutive patients with PPU were enrolled in this study. The mean age was 43.1 +/- 12.2 years. Male to female ratio was 27:2. One patient was excluded from laparoscopic repair due to a gastric outlet obstruction. The other 29 patients were managed according to a protocol of preoperative upper endoscopy and laparoscopic intracorporeal suture repair with an omental patch. The average operative time was 58.1 +/- 13.5 minutes (range, 36-96 min). The average diameter of perforation was 4.2 +/- 2.0 mm (range, 1-12 mm). The average time to resume oral fluids was 3.2 +/- 0.8 days (range, 2-8 days). The average hospital stay was 4.7 +/- 1.1 days (range, 3-10 days). There was no leakage or mortality. Most patients did not receive parenteral analgesics postoperatively. We conclude that endoscope-assisted laparoscopic repair for PPU is safe and effective. This revised technique allows surgeons to exclude patients who are likely to fail the laparoscopic repair.

Urothelial Carcinoma Recurrence at an Ileal Orthotopic Neobladder and Unilateral Lower Ureter After Surgery

2016-11-01

Full Text Available The recurrence of urothelial carcinoma in an orthotopic neobladder is rare. We report the case of a 61-year-old man with a muscle-invasive bladder tumor that was treated using radical cystectomy and the creation of a Studer's orthotopic neobladder. However, nine years after the cystectomy, we detected a mass at the left ureteroileal anastomosis. We successfully performed Studer's neobladder resection, urethrectomy, and left nephroureterectomy to remove the entire mass. Pathological examination revealed urothelial carcinoma with adenocarcinoma in the neobladder and adenocarcinomatous metastasis in the mesenteric lymph node.

Surgical resection is currently the only treatment with the potential for long-term survival and cure of pancreatic cancer. Surgical resection is provided as distal pancreatectomy for cancers of the body and tail of the pancreas. It can be performed by laparoscopic or open surgery. In operations on other organs, laparoscopic surgery has been shown to reduce complications and length of hospital stay as compared with open surgery. However, concerns remain about the safety of laparoscopic distal pancreatectomy compared with open distal pancreatectomy in terms of postoperative complications and oncological clearance. To assess the benefits and harms of laparoscopic distal pancreatectomy versus open distal pancreatectomy for people undergoing distal pancreatectomy for pancreatic ductal adenocarcinoma of the body or tail of the pancreas, or both. We used search strategies to search the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, Science Citation Index Expanded and trials registers until June 2015 to identify randomised controlled trials (RCTs) and non-randomised studies. We also searched the reference lists of included trials to identify additional studies. We considered for inclusion in the review RCTs and non-randomised studies comparing laparoscopic versus open distal pancreatectomy in patients with resectable pancreatic cancer, irrespective of language, blinding or publication status.. Two review authors independently identified trials and independently extracted data. We calculated odds ratios (ORs), mean differences (MDs) or hazard ratios (HRs) along with 95% confidence intervals (CIs) using both fixed-effect and random-effects models with RevMan 5 on the basis of intention-to-treat analysis when possible. We found no RCTs on this topic. We included in this review 12 non-randomised studies that compared laparoscopic versus open distal pancreatectomy (1576 participants: 394 underwent laparoscopic distal pancreatectomy and 1182

Purpose To evaluate changes in clinical and pathological characteristics of prostate cancer in patients treated surgically at a large tertiary care center in the context of increased use of active surveillance (AS) and minimally invasive surgery (MIS). Materials We performed retrospective review of 6,624 patients with localized prostate cancer who underwent radical prostatectomy from 2000–2010 at Memorial Sloan-Kettering Cancer Center. Patients were stratified by surgical approach (open, laparoscopic or robotic) and risk categories (low, intermediate, or high). Patients with low-risk disease, without intervention and minimum followup of 6 months were considered to have elected AS. Results AS cases increased from <20 per year between 2000–2004 to ≥100 per year between 2007–2009. Over the same decade MIS cases (laparoscopic or robotic) increased from zero to 63% of all surgical cases. The percentage of patients in intermediate- and high-risk categories increased over time, while the percentage in the low-risk category decreased (OR per year 0.91, 95% CI 0.89, 0.92, p <0.0005). The proportion of surgery patients with Gleason 6 tumors decreased over time (OR per year 0.87, 95% CI 0.85, 0.88; p <0.0005) while pathologic stage and Gleason score increased (p <0.0005). The proportion of low-risk cases decreased across all types of surgery, with the largest decrease in robotic surgery (p <0.0005). Conclusions We observed a reverse stage shift in patients undergoing radical prostatectomy since 2000 despite the introduction and rapid proliferation of MIS. These findings may be due to increased use of AS and institutional focus on treatment of higher-risk disease. PMID:21484780

Altogether 142 papers were found using the reported search, of which seven represented the best evidence to answer the clinical question. The details of the papers were tabulated including relevant outcomes and study weaknesses. We conclude that medical students and experienced laparoscopic surgeons with ongoing video game experience have superior laparoscopic skills for simulated tasks in terms of time to completion, improved efficiency and fewer errors when compared to non-gaming counterparts. There is some evidence that this may be due to better psycho-motor skills in gamers, however further research would be useful to demonstrate whether there is a direct transfer of skills from laparoscopic simulators to the operating table.

Laparoscopic colectomies, with and without robotic assistance, are performed to treat both benign and malignant colonic disease. This study compared clinical and economic outcomes for laparoscopic colectomy procedures with and without robotic assistance. Patients aged ≥18 years having primary inpatient laparoscopic colectomy procedures (cecectomy, right hemicolectomy, left hemicolectomy, and sigmoidectomy) identified by International Classification of Diseases, Ninth Edition procedure codes performed between 2009 and the second quarter of 2011 from the Premier Hospital Database were studied. Patients were matched to a control cohort using propensity scores for disease, comorbidities, and hospital characteristics and were matched 1:1 for specific colectomy procedure. The outcomes of interest were hospital cost of laparoscopic robotic-assisted colectomy compared with traditional laparoscopic colectomy, surgery time, adverse events, and length of stay. Of 25,758 laparoscopic colectomies identified, 98% were performed without robotic assistance and 2% were performed with robotic assistance. After matching, 1066 patients remained, 533 in each group. Lengths of stay were not significantly different between the matched cohorts, nor were rates of major, minor, and/or surgical complications. Inpatient procedures with robotic assistance were significantly more costly than those without robotic assistance ($17,445 vs $15,448, P = .001). Operative times were significantly longer for robotic-assisted procedures (4.37 hours vs 3.34 hours, P < .001). Segmental colectomies can be performed safely by either laparoscopic or robotic-assisted methods. Increased per-case hospital costs for robotic-assisted procedures and prolonged operative times suggest that further investigation is warranted when considering robotic technology for routine laparoscopic colectomies.

One of the commonest forms of orthotopic bladder substitution for bladder cancer surivors, used in our institute, is the use of ileocecal segment. Sometimes, the need for Indiana pouch heterotropic continent diversion arises. Aim: To compare the long-term effect of orthotopic ileocecal bladder and heterotropic Indiana pouch following radical cystectomy in bladder cancer patients. Patients and methods: Between January 2008 and December 2011, 91 patients underwent radical cystectomy/anterior pelvic exentration and ortho topic ileocecal bladder reconstruction (61 patients) and Indiana pouch (30 patients), when orthotopic diversion could not be technically or oncologically feasible. Results: Convalescence was uneventful in most patients. All minor and major urinary leakage cases, in both diversions groups, where successfully conservatively treated. Only one patient in the ileocecal group with major urinary leak required re-exploration with successful revision of uretro-colonic anastomosis. Only one patient in the Indiana pouch group had accidentally discovered sub-centimetric stone, which was simply expelled. The overall survival proportion of ileocecal group was 100% compared to 80% in the Indiana pouch group (p < 0.001). The disease free survival proportion of ileocecal group was 90.8% compared to 80% in the Indiana pouch group (p = 0.076). Effective comparative daytime and nighttime urinary continence as well as renal function deterioration were not statistically significant between both reconstruction types. Conclusion: Both ileocecal bladder and Indiana pouch are safe procedures in regard to long-term effects over kidney function following radical cystectomy

In the current age of minimally invasive surgery, laparoscopic surgery for colon cancer has been established as oncologically equivalent to conventional open surgery. The advantages of laparoscopic surgery have translated into smaller incisions and shorter recovery. Since the advent of laparoscopy, surgeons have been fueled to develop less invasive operative methods as feasible alternatives to traditional procedures. As techniques evolved and technology advanced, laparoscopy became more widely accepted and is now more commonly used in many institutions. Recently, a trend toward less invasive surgery, driven by patient and surgeon alike, has been a major objective for many institutions because of the ability of laparoscopic surgery to reduce postoperative pain, achieve a quicker recovery time, and improve cosmetic outcomes. Although still evolving, traditional laparoscopy has served as a foundation for even further refinements in the minimally invasive approach and as a result, more advanced equipment and newer techniques have arisen
