The role of splenic flexure mobilization in laparoscopic rectal surgery for rectal cancer

CONTEXT: Failure of a colorectal anastomosis represents a life-threatening complication of colorectal surgery. Splenic flexure mobilization may contribute to reduce the occurrence of anastomotic complications due to technical flaws. There are no published reports measuring the impact of splenic flexure mobilization on the length of mobilized colon viable to construct a safe colorectal anastomosis. OBJECTIVE: The aim of the present study was to determine the effect of two techniques for splenic flexure mobilization on colon lengthening during open left-sided colon surgery using a cadaver model. DESIGN: Anatomical dissections for left colectomy and colorectal anastomosis at the sacral promontory level were conducted in 20 fresh cadavers by the same team of four surgeons. The effect of partial and full splenic flexure mobilization on the extent of mobilized left colon segment was determined. SETTING: University of Sao Paulo Medical School, Sao Paulo, SP, Brazil. Tertiary medical institution and university hospital. PARTICIPANTS: A team of four surgeons operated on 20 fresh cadavers. RESULTS: The length of resected left colon enabling a tension-free colorectal anastomosis at the level of sacral promontory achieved without mobilizing the splenic flexure was 46.3 (35-81) cm. After partial mobilization of the splenic flexure, an additionally mobilized colon segment measuring 10.7 (2-30) cm was obtained. After full mobilization of the distal transverse colon, a mean 28.3 (10-65) cm segment was achieved. CONCLUSION: Splenic flexure mobilization techniques are associated to effective left colon lengthening for colorectal anastomosis. This result may contribute to decision-making during rectal surgery and low colorectal and coloanal anastomosis.

Introduction. Single-access laparoscopic surgery (SALS) has been successfully introduced for colectomy surgery; however, for mid to low rectum procedures such as total mesorectal excision, it can be technically complicated. In this study, we introduced a single-access technique for rectum cancer operations without the use of other instruments.Aims. To show the short-term results of single-access laparoscopic rectal surgery in terms of pathologic results and immediate complications.Settings and Design. Prospective study.Materials and Methods. We selected middle rectum to anal canal cancer patients to undergo single-access laparoscopic rectal resection for rectal cancer. All patients had total mesorectal excisions. An umbilical incision was made for the insertion of a single multichannel port, and a mesocolic window was created to identify the inferior mesenteric artery and vein. Total mesorectal excision was performed. There were no perioperative complications. The mean operative time was 269 minutes; the median hospital stay was 7 days; the mean wound size was 5.5 cm; the median number of harvested lymph nodes was 15; and all patients had intact mesorectal capsules.Statistical Analysis Used. Mean, minimum–maximum.Conclusion. Single-access laparoscopic surgery for rectal cancer is feasible while oncologic principles and patient safety are maintained.

Background: The use of splenic ﬂexure mobilization (SFM) for rectal cancer surgery is still controversial. SFM includes division of the splenocolic, phrenocolic, gastrocolic and pancreaticomesocolic ligaments, which is time-consuming. The aim of present prospective study of low anterior resection in case of cancer rectum was to compare splenic ﬂexure mobilization (SFM) carried out by an extended medial approach with that by a lateral approach.Methods: A prospective study was carried out in General Surgery Department, Menoufia University, Egypt between October 2017 and December 2018. Patients were allocated randomly into two groups in which first group (group A) allocated to medial mobilization of splenic flexure and the second group was allocated into lateral approach of splenic flexure. The extended medial involved continuing the medial to lateral approach upwards to enter the lesser sac over the pancreas, thus permitting detachment of the splenic ﬂexure. However, lateral approach involves dissection of retroperitoneal fascia.Results: Thirty patients, including 20 undergoing a lateral SFM and 10 an extended medial SFM, were evaluated. Mean number of lymph nodes in lateral and medial approach are (17.7±5.6, 24.3±6 respectively) with significant (P-value=0.04). Interestingly, Intra-operative blood loss in lateral approach is more than medial approach (175±25.3, 160.1±30 respectively) with significant (p-value=0.02). The interval to oral intake (3±0.3 days extended medial, 4.1±0.7 lateral, P=0.14).Conclusions: An extended medial approach for SFM during low anterior resection of rectal cancer appears to be an improvement over the previously used lateral approach because it may provide a shorter operation time and higher number of harvested lymph nodes with less intra-operative blood loss.

Laparoscopic Rectal Surgery

Abstract Background Endoscopic treatment for gastrointestinal cancer can cause inflammation, edema, and fibrosis formation in the surrounding tissue. Recently, we reported that preceding endoscopic treatment increased the volume of intraoperative blood loss and slightly prolonged the operative time of laparoscopic surgery for rectal cancer. In this study, we addressed which factors, including endoscopic submucosal dissection (ESD)- related parameters, affect the difficulty of laparoscopic rectal surgery. Methods We retrospectively reviewed 24 consecutive patients who underwent ESD followed by laparoscopic surgery for rectal cancer in our hospital. Short-term surgical outcomes were evaluated by intraoperative blood loss and operative time for laparoscopic surgery. The correlations between the surgical outcomes and preoperative parameter were analyzed by scatter diagrams and multiple linear regression analyses. Results The patient cohort comprised 12 men and 12 women. The median distance between primary cancer and anal verge was 7 cm. The median procedure time of ESD was 120 minutes (21 available cases). The scatter diagram graph revealed a positive correlation between the ESD procedure time and estimated blood loss during rectal surgery (rs = 0.26). There was no association between the ESD procedure time and operative time for rectal surgery. Based on multiple linear regression analyses, the ESD procedure time (p = 0.007) and tumor location from the anal verge (p = 0.046) were independently predictive of intraoperative blood loss. On the other hand, only tumor location was found an independent predictor of surgical time (p = 0.014). Conclusions A long session of ESD for rectal cancer may make subsequent laparoscopic surgery difficult based on intraoperative blood loss.
