Project description:BackgroundInguinal lymphadenectomy (iLAD) is effective for penile carcinoma treatment, but usually results in many complications. This study aims to clinically evaluate the feasibility and clinical significance of a laparoscopic radical iLAD approach partly preserving great saphenous vein branches for penile carcinoma patients.MethodsA total of 48 patients with penile cancer who underwent laparoscopic radical iLAD with retention of the great saphenous vein in Henan Cancer Hospital from 2012 Jan to 2020 Dec were included in this study. Sixteen penile carcinoma patients who underwent laparoscopic radical iLAD preserving parts of superficial branches of the great saphenous vein were identified as the sparing group, and the matched 32 patients who incised those branches were identified as control group. This new procedure was performed by laparoscopy, preserving parts of superficial branches of the great saphenous vein, superficial lateral and medial femoral veins. Clinicopathological features and perioperative variables were recorded. Postoperative complications, including skin flap necrosis, lymphorrhagia, and lower extremity edema were analyzed retrospectively.ResultsWe found that the operative time of the sparing group is significantly longer than the control group (p = 0.011). There was no statistical difference in intraoperative blood loss, the lymph node number per side, average time to remove the drainage tube and postoperative hospital stay between the two groups. Compared to the control group, the sparing group showed a significantly decreased incidence of lower extremity edema (p = 0.018). The preservation of parts of superficial branches of the great saphenous vein was mainly decreased the incidence of edema below ankle (p = 0.034).ConclusionsThis study demonstrated that the iLAD with preserving parts of superficial branches of the great saphenous vein, with a decreased incidence of postoperative complications, is a safe and feasible approach for penile cancer.

Project description:BackgroundSelected studies have reported improved outcomes in laparoscopic compared with open distal pancreatic resection. Concerns regarding failure to achieve proper oncological resection and compromised long-term outcomes remain. This study investigated whether postoperative outcomes and long-term survival after laparoscopic distal pancreatectomy are comparable to those after an open procedure.MethodsThis retrospective case-control study included patients who underwent distal pancreatectomy for resectable pancreatic adenocarcinoma between 2010 and 2013, identified from the National Cancer Database. Propensity score nearest-neighbour 1 : 1 matching was performed between patients undergoing laparoscopic or open distal pancreatectomy based on all relevant co-variables. The primary outcome was overall survival.ResultsOf 1947 eligible patients, 605 (31·1 per cent) underwent laparoscopic distal pancreatectomy. After propensity score matching, two well balanced groups of 563 patients each were analysed. There was no difference in overall survival at 3 years after laparoscopic versus open distal pancreatectomy (41·6 versus 36·0 per cent; hazard ratio 0·93, 95 per cent c.i. 0·77 to 1·12; P = 0·457). The overall conversion rate was 27·3 per cent (165 of 605). Patients who underwent laparoscopic distal pancreatectomy had outcomes comparable to those of patients who had an open procedure with regard to median time to chemotherapy (50 versus 50 days; P = 0·342), median number of nodes examined (12 versus 12; P = 0·759); 30-day mortality (1·2 versus 0·9 per cent; P = 0·562); 90-day mortality (2·8 versus 3·7 per cent; P = 0·403), 30-day readmission rate (9·6 versus 9·2 per cent; P = 0·838) and positive margin rate (14·9 versus 18·5 per cent; P = 0·110). However, median duration of hospital stay was shorter in the laparoscopic group (6 versus 7 days; P < 0·001).ConclusionLaparoscopic distal pancreatectomy is an acceptable alternative to open distal pancreatectomy with no detriment to survival.

Project description:Accurate mediastinal lymph node dissection during thoracotomy is mandatory for staging and for adjuvant therapy in lung cancer. Pre-therapeutic staging for neoadjuvant therapy or for video assisted thoracoscopic resection of lung cancer is achieved usually by CT-scan and mediastinoscopy. However, these methods do not reach the accuracy of open nodal dissection. Therefore we developed a technique of radical video-assisted mediastinoscopic lymphadenectomy (VAMLA). This study was designed to show that VAMLA is feasible and that radicality of lymphadenectomy is comparable to the open procedure.In a prospective study all VAMLA procedures were registered and followed up in a database. Specimens of VAMLA were analysed by a single pathologist. Lymph nodes were counted and compared to open lymphadenectomy. The weight of the dissected tissue was documented. In patients receiving tumour resection subsequently to VAMLA, radicality of the previous mediastinoscopic dissection was controlled during thoracotomy.37 patients underwent video-assisted mediastinoscopy from June 1999 to April 2000. Mean duration of anaesthesia was 84.6 (SD 35.8) minutes.In 7 patients radical lymphadenectomy was not intended because of bulky nodal disease or benign disease. The remaining 30 patients underwent complete systematic nodal dissection as VAMLA.18 patients received tumour resection subsequently (12 right- and 6 left-sided thoracotomies). These thoracotomies allowed open re-dissection of 12 paratracheal regions, 10 of which were found free of lymphatic tissue. In two patients, 1 and 2 left over paratracheal nodes were counted respectively. 10/18 re-dissected subcarinal regions were found to be radically dissected by VAMLA. In 6 patients one single node and in the remaining 2 cases 5 and 8 nodes were found, respectively. However these counts also included nodes from the ipsilateral main bronchus. None of these nodes was positive for tumour.Average weight of the tissue that was harvested by VAMLA was 10.1 g (2.2-23.7, SD 6.3). An average number of 20.5 (6-60, SD 12.5) nodes per patient were counted in the specimens. This is comparable to our historical data from open lymphadenectomy.One palsy of the recurrent nerve in a patient with extensive preparation of the nerve and resection of 11 left-sided enlarged nodes was the only severe complication in this series.VAMLA seems to accomplish mediastinal nodal dissection comparable to open lymphadenectomy and supports video assisted surgery for lung cancer. In neoadjuvant setting a correct mediastinal N-staging is achieved.

Project description:Introduction: Salvage lymph node dissection (sLND) has been proposed as a treatment option for prostate cancer patients with lymph node (LN) recurrence following radical prostatectomy to delay or avoid palliative androgen deprivation therapy (ADT). Historically sLND has been performed using an open approach, with its associated morbidity. A limited number of studies have reported peri-operative outcomes following robot-assisted sLND. However, a direct comparison with the open approach has hitherto not yet been reported. This study investigates whether robot-assisted sLND is associated with better peri-operative outcomes compared to the open approach. Early oncological outcomes are also compared. Patients and methods: In this retrospective study, clinical data were collected from 60 patients undergoing open sLND between 2010-2016 and 30 patients undergoing robot-assisted sLND between 2016 and 2018 at our tertiary referral center. The primary objective of the study was to compare peri-operative outcomes (length of stay, estimated blood loss, operative time, intra-operative, and postoperative complications) and LN yield between both procedures. As secondary objective early oncological outcome [biochemical recurrence-free survival (BRFS) and clinical recurrence-free survival (CRFS)] was compared. Variables of interest were compared using the chi-squared test (categorical variables), two sample t-test, and Mann-Whitney U-test (continuous variables). To compare BRFS and CRFS, Kaplan-Meier analysis, and log-rank tests were performed. Results: Robotic sLND was associated with reduced blood loss (median 100 vs. 275cc; p < 0.0001) and shorter length of stay (median 2 vs. 7 days; p < 0.0001) compared to open sLND. Moreover, postoperative complications within 30 days after surgery were more prevalent in the open sLND group compared to the robotic group (41.6% vs. 20%, p = 0.04). No significant differences in LN yield (for each sLND template), BRFS, and CRFS were detected between both groups. Conclusion: Robot-assisted sLND is associated with significantly reduced peri-operative morbidity compared to open sLND. No difference in LN yield, BRFS and CRFS was seen between both groups. Modern imaging techniques underestimate the tumor burden and therefore, the surgical sLND template should not be limited to the positive spots on pre-operative imaging.
