Project description:Lymphatic ascites is a postoperative complication of lymph node dissection. Most symptomatic cases improve with conservative treatments. However, optimal management strategies for intractable lymphatic ascites remain controversial, and clinicians sometimes encounter intractable lymphatic ascites that does not respond to conservative management. We herein report a case of postoperative intractable lymphatic ascites that was successfully treated with intranodal lymphangiography (LG) from inguinal lymph nodes under microsurgery. A 56-year-old woman was diagnosed with stage II endometrial cancer and underwent total abdominal hysterectomy, bilateral salpingo-oophorectomy, and pelvic and para-aortic lymphadenectomies. On postoperative day (POD) 13, the patient presented with abdominal distention, and lymphatic ascites was diagnosed. Although the patient was treated with conservative management and lymphaticovenular anastomosis, her lymphatic ascites did not resolve. Finally, intranodal LG from the inguinal region was performed under microsurgery. A 2-cm incision was made on each side of the inguinal region. Once the lymph nodes were identified, a 23-gauge needle was inserted into the lymph node and lipiodol was injected. Extravasation of lipiodol into the abdomen from the left side of the lower pelvic region was confirmed. The postoperative course was uneventful. The ascites gradually decreased and disappeared within two weeks after LG.

Project description:ObjectiveTo determine the effectiveness of pelvis diameters in determining postoperative outcomes in men who underwent open radical cystectomy + urinary diversion, it is aimed to predict the factors that may affect the operative difficulty and possible surgical outcomes before the operation.MethodsA total of 79 radical cystectomy patients operated in our institution with preoperative computed tomography (CT) were included the study. Pelvic dimensions; symphysis angle (SA), upper conjugate, lower conjugate, pelvic depth, apical depth (AD), interspinous distance (ISD), bone femoral width and soft tissue width were measured by preoperative CT. ISD index were defined as ISD/AD. Postoperative outcomes and indicators of operative difficulty were recorded. Regression analyses were used to predict perioperative and postoperative outcomes.ResultsTotal of 96 complications were observed in 52 of the 79 patients in ninety days (65,8%) with a mean age of 68.25 years. There were significant correlations between SA and body mass index (BMI) with operative time (p = 0.006, p < 0.001; respectively). For estimated blood loss, there were significant correlations between preoperative hematocrit (p = 0,031). Analysis of multivariate logistic regression revealed that higher Charlson comorbidity index (CCI) and BMI were found to be significant predictors for major complications while CCI, pathological T stage and ISD index are prominent predictors for surgical margin positivity.ConclusionsPelvic dimensions are not significant with minor or major complications. However, operative time may be associated with SA. Also, narrow and deep pelvis may increase the risk of positive surgical margins.

Project description:Intranodal lymphangiography (IL) has supplanted pedal lymphangiography (PL) as an easier and more practical approach to opacifying lymphatic vessels for interventional radiologists treating refractory chyle leaks. As more interventional radiologists-many of who are not trained in or have not performed PL-incorporate IL into their practice, it is imperative that they be familiar with the risks of lymphangiography, including pulmonary and systemic embolization of oily contrast material. Herein, the authors report a devastating case of cerebral embolization of ethiodized oil following IL and review the literature regarding systemic embolization following lymphangiography.

Project description:An adequate pelvic lymph node dissection (PLND) is an essential part of radical cystectomy for muscle invasive bladder cancer. However, the definition of what constitutes an adequate PLND is often shrouded in controversy. Various authors have defined different anatomic templates of PLND based on levels of pelvic lymph nodes. Some have suggested other surrogate markers of the adequacy of PLND, namely lymph node count and lymph node density. While individual studies have shown the efficacy and reliability of some of the above markers, none of them have been recommended forthright due to the absence of robust prospective data. The use of non-standardized nomenclature while referring to the above variables has made this matter more complex. Most of older data seems to favor use of extended template of PLND over the standard template. On the other hand, one recent randomized controlled trial (RCT) did not show any benefit of one template over the other in terms of survival benefit, but the study design allowed for a large margin of bias. Therefore, we conducted a systematic search of literature using EMBASE, Medline, and PubMed using PRISMA-P checklist for articles in English Language published over last 20 years. Out of 132 relevant articles, 47 articles were included in the final review. We have reviewed existing literature and guidelines and have attempted to provide a few suggestions toward a uniform nomenclature for the various anatomical descriptions and the extent of PLND done while doing a radical cystectomy. The results of another large RCT (SWOG S1011) are awaited and until we have a definitive evidence, we should adhere to these suggestions as much as possible and deal with each patient on a case to case basis.

Project description:Radical cystectomy is the standard of care for patients with nonmetastatic high-risk bladder cancer. Robotic approach to radical cystectomy has been developed to reduce perioperative morbidities and enhance postoperative recovery while maintaining oncologic control. Classically, radical cystectomy in female patient entails anterior pelvic exenteration with removal of the bladder, uterus, fallopian tubes, ovaries, anterior vaginal wall, and urethra. Pelvic organ-sparing radical cystectomy has been adopted in carefully selected patients to optimize postoperative sexual and urinary function, especially in those undergoing orthotopic urinary diversion. In this article, we describe our techniques of both classical and organ-sparing robot-assisted laparoscopic radical cystectomy in female patients. We also review patient selection criteria, perioperative management, and alternative approaches to improve operative outcomes in female patients.

Project description:Introduction:Open radical cystectomy (ORC) has been the standard treatment for muscle-invasive bladder cancer, but this is associated with significant morbidity and mortality. Robot-assisted radical cystectomy (RARC) has been proposed as minimally invasive alternative with improved morbidity and acceptable oncological outcomes, but a large series featuring RARC and their comparison with ORC is still lacking in India despite more than a decade of its inception. We have conducted this study with an objective to see the feasibility of RARC in the Indian context and compare it with contemporary standard. Methods:This is a prospective cohort study conducted at two tertiary cancer institutes. We have evaluated the patients pertaining to operative and early post-operative factors from January 2014 to December 2015. Necessary statistical tests applied to see comparability of the arms and their outcomes. Results:A total of 170 patients underwent surgery for carcinoma bladder (45 ORC while 125 RARC). Intraoperative blood loss (RARC and ORC: 228 and 529 ml) and average transfusion rate were lower with RARC. A trend towards benefit was noted in favour of robotic arm in terms of mean complication rate (RARC and ORC: 54 and 39%). Conclusions:The present study has shown comparable surgical and early post-operative outcomes with clear advantage of robotic approach in terms of intraoperative blood transfusion and lymph node yield. Although the study was non-randomised in nature, it should provide substantial evidence on safety and feasibility of RARC in the Indian context and a reference point of evidence to look ahead.

Project description:Open radical cystectomy (ORC) and urinary diversion in patients with bladder cancer (BCa) are associated with significant perioperative complication risk.To compare perioperative complications between robot-assisted radical cystectomy (RARC) and ORC techniques.A prospective randomized controlled trial was conducted during 2010 and 2013 in BCa patients scheduled for definitive treatment by radical cystectomy (RC), pelvic lymph node dissection (PLND), and urinary diversion. Patients were randomized to ORC/PLND or RARC/PLND, both with open urinary diversion. Patients were followed for 90 d postoperatively.Standard ORC or RARC with PLND; all urinary diversions were performed via an open approach.Primary outcomes were overall 90-d grade 2-5 complications defined by a modified Clavien system. Secondary outcomes included comparison of high-grade complications, estimated blood loss, operative time, pathologic outcomes, 3- and 6-mo patient-reported quality-of-life (QOL) outcomes, and total operative room and inpatient costs. Differences in binary outcomes were assessed with the chi-square test, with differences in continuous outcomes assessed by analysis of covariance with randomization group as covariate and, for QOL end points, baseline score.The trial enrolled 124 patients, of whom 118 were randomized and underwent RC/PLND. Sixty were randomized to RARC and 58 to ORC. At 90 d, grade 2-5 complications were observed in 62% and 66% of RARC and ORC patients, respectively (95% confidence interval for difference, -21% to -13%; p=0.7). The similar rates of grade 2-5 complications at our mandated interim analysis met futility criteria; thus, early closure of the trial occurred. The RARC group had lower mean intraoperative blood loss (p=0.027) but significantly longer operative time than the ORC group (p<0.001). Pathologic variables including positive surgical margins and lymph node yields were similar. Mean hospital stay was 8 d in both arms (standard deviation, 3 and 5 d, respectively; p=0.5). Three- and 6-mo QOL outcomes were similar between arms. Cost analysis demonstrated an advantage to ORC compared with RARC. A limitation is the setting at a single high-volume, referral center; our findings may not be generalizable to all settings.This trial failed to identify a large advantage for robot-assisted techniques over standard open surgery for patients undergoing RC/PLND and urinary diversion. Similar 90-d complication rates, hospital stay, pathologic outcomes, and 3- and 6-mo QOL outcomes were observed regardless of surgical technique.Of 118 patients with bladder cancer who underwent radical cystectomy, pelvic lymph node dissection, and urinary diversion, half were randomized to open surgery and half to robot-assisted laparoscopic surgery. We compared the rate of complications within 90 d after surgery for the open group versus the robotic group and found no significant difference between the two groups.ClinicalTrials.gov identifier NCT01076387, www.clinicaltrials.gov.

Project description:INTRODUCTION:We sought to determine whether non-mandated or passive centralization of radical cystectomy (RC) to higher-volume centers leads to enhanced processes of care and outcomes. METHODS:This is a population-based, retrospective, cohort study that used the Ontario Cancer Registry (OCR) to identify all incident patients who underwent RC from 1994-2013. Electronic records of treatment were linked to OCR; pathology records were obtained for all cases and reviewed by a team of trained data abstractors. The primary objective was to describe annual provider RC volumes. Secondary objectives included investigating process and outcome measures. RESULTS:For the 5574 patients identified, the mean annual surgeon volume and hospital volume of RC from 1994-2008 was 4.5 (95% confidence interval [CI] 4.4-4.7) and 12.2 (95% CI 11.8-12.5), respectively. From 2009-2013, these volumes significantly increased to 6.8 (95% CI 6.5-7. 1) and 16.4 (95% CI 15.8-16.9). Process variables improved over time, including the use of neoadjuvant chemotherapy. Over the study period, there was a substantial improvement in cancer-specific survival (CSS): hazard ratio (HR) 0.60 (95% CI 0.53-0.67) for 2009-2013. During the most recent era, there was still evidence of a provider volume effect on both process measures and CSS. CONCLUSIONS:There has been recent passive centralization of RC to higher-volume providers in the province of Ontario, with measurable improvements in processes of quality care. Although centralization was also associated with improvement in CSS, in the most recent era, there continues to be low-volume providers with a residual volume-outcome effect.

Project description:A 40-year-old woman underwent laparoscopic common iliac lymphadenectomy for metastasis from rectal cancer. Two weeks after the surgery, she was found to have massive chylous ascites. After failure of conservative treatment, bilateral inguinal intranodal lymphangiography was performed. No definite extravasation was observed while lipiodol injected through the left inguinal node was ascending. When we punctured the right inguinal lymph nodes and started the injection of lipiodol, extravasation of diluted lipiodol was noted at the level of the first sacrum. Careful observation revealed that the ascending lipiodol became diluted in the cisterna chyli, refluxed through the median paraaortic route, leaked from the excised left common iliac lymph vessel, and flowed into the abdominal cavity. Lipiodol used in lymphangiography did not reduce chylous ascites at all. Twenty-seven days after lymphangiography, laparoscopic lymphatic ligation was performed, and the chylous ascites disappeared completely. CT obtained 40 days after surgical repair revealed disappearance of ascites and enlargement of the thoracic duct, which had not been observed on preoperative lymphangiography. Notably, lymphatic reflux from the cisterna chili can occur without obstruction of the thoracic duct and may result in chylous ascites.

Project description:ImportanceThe value to payers of robot-assisted radical cystectomy with intracorporeal urinary diversion (iRARC) when compared with open radical cystectomy (ORC) for patients with bladder cancer is unclear.ObjectivesTo compare the cost-effectiveness of iRARC with that of ORC.Design, setting, and participantsThis economic evaluation used individual patient data from a randomized clinical trial at 9 surgical centers in the United Kingdom. Patients with nonmetastatic bladder cancer were recruited from March 20, 2017, to January 29, 2020. The analysis used a health service perspective and a 90-day time horizon, with supplementary analyses exploring patient benefits up to 1 year. Deterministic and probabilistic sensitivity analyses were undertaken. Data were analyzed from January 13, 2022, to March 10, 2023.InterventionsPatients were randomized to receive either iRARC (n = 169) or ORC (n = 169).Main outcomes and measuresCosts of surgery were calculated using surgery timings and equipment costs, with other hospital data based on counts of activity. Quality-adjusted life-years were calculated from European Quality of Life 5-Dimension 5-Level instrument responses. Prespecified subgroup analyses were undertaken based on patient characteristics and type of diversion.ResultsA total of 305 patients with available outcome data were included in the analysis, with a mean (SD) age of 68.3 (8.1) years, and of whom 241 (79.0%) were men. Robot-assisted radical cystectomy was associated with statistically significant reductions in admissions to intensive therapy (6.35% [95% CI, 0.42%-12.28%]), and readmissions to hospital (14.56% [95% CI, 5.00%-24.11%]), but increases in theater time (31.35 [95% CI, 13.67-49.02] minutes). The additional cost of iRARC per patient was £1124 (95% CI, -£576 to £2824 [US $1622 (95% CI, -$831 to $4075)]) with an associated gain in quality-adjusted life-years of 0.01124 (95% CI, 0.00391-0.01857). The incremental cost-effectiveness ratio was £100 008 (US $144 312) per quality-adjusted life-year gained. Robot-assisted radical cystectomy had a much higher probability of being cost-effective for subgroups defined by age, tumor stage, and performance status.Conclusions and relevanceIn this economic evaluation of surgery for patients with bladder cancer, iRARC reduced short-term morbidity and some associated costs. While the resulting cost-effectiveness ratio was in excess of thresholds used by many publicly funded health systems, patient subgroups were identified for which iRARC had a high probability of being cost-effective.Trial registrationClinicalTrials.gov Identifier: NCT03049410.
