Single-incision Plus One Port Laparoscopic Total Mesorectal Excision and Bilateral Pelvic Node Dissection for Advanced Rectal Cancer--A Medial Umbilical Ligament Approach.

ABSTRACT: We prove the safety and feasibility of single-incision plus 1 port (SILS+1) laparoscopic total mesorectal excision (TME) + lateral pelvic lymph node dissection (LPLD) via a medial umbilical approach for rectal cancer. Only a few reports have been published about single-incision multiport laparoscopic low anterior resection with LPLD. Recently, minimally invasive surgery such as single-incision plus 1 port (SILS + 1) for advanced rectal cancer has been reported as safe and feasible. To our knowledge, this is the first reported case of SILS + 1 used for LPLD. A wound protector was inserted through a 30-mm transumbilical incision. Next, a single-port access device was mounted to the wound protector and 3 ports (5 mm each) were placed. A 12-mm port was inserted in the right lower quadrant. Super-low anterior resection of the rectum and bilateral LPLD and temporary ileostomy were performed with SILS + 1, with a blood loss of 50 mL and a total surgical time of 525 minutes. The time for right lateral dissection was 74 minutes; the time for left lateral dissection was 118 minutes. The total number of dissected lymph nodes was 57 and the number of lateral lymph nodes dissected was 21 (8 left pelvic lymph nodes, 13 right pelvic lymph nodes). No postoperative anastomotic insufficiency or voiding dysfunction was observed. We have documented the safety and feasibility of SILS + 1-TME + LPLD via a medial umbilical approach for rectal cancer.

Project description:AimsThe role of laparoscopy in rectal cancer has been questioned. 3D laparoscopic systems are suggested to aid optimal surgical performance but have not been evaluated in advanced procedures. We hypothesised that stereoscopic imaging could improve the performance of laparoscopic total mesorectal excision (TME).MethodsA multicentre developmental randomised controlled trial comparing 2D and 3D laparoscopic TME was performed (ISRCTN59485808). Trial surgeons were colorectal consultants that had completed their TME proficiency curve and underwent stereoscopic visual testing. Patients requiring elective laparoscopic TME with curative intent were centrally randomised (1:1) to 2D or 3D using Karl Storz IMAGE1 S D3-Link™ and 10-mm TIPCAM®1S 3D passive polarising laparoscopic systems. Outcomes were enacted adverse events as assessed by the observational clinical human reliability analysis technique, intraoperative data, 30-day patient outcomes, histopathological specimen assessment and surgeon cognitive load.Results88 patients were included. There were no differences in patient or tumour demographics, surgeon stereopsis, case difficulty, cognitive load, operative time, blood loss or conversion between the trial arms. 1377 intraoperative adverse events were identified (median 18 per case, IQR 14-21, range 2-49) with no differences seen between the 2D and 3D arms (18 (95% CI 17-21) vs. 17 (95% CI 16-19), p?=?0.437). 3D laparoscopy had non-significantly higher mesorectal fascial plane resections (94 vs. 77%, p?=?0.059; OR 0.23 (95% CI 0.05-1.16)) but equal lymph node yield and circumferential margin distance and involvement. 30-day morbidity, anastomotic leak, re-operation, length of stay and readmission rates were equal between the 2D and 3D arms.ConclusionFeasibility of performing multicentre 3D laparoscopic multicentre trials of specialist performed complex procedures is shown. 3D imaging did not alter the number of intraoperative adverse events; however, a potential improvement in mesorectal specimen quality was observed and should form the focus of future 3D laparoscopic TME trials.
