Abstract
BACKGROUND: Following resection for low rectal cancer, numerous patients suffer from frequent bowel movements, fecal urgency, and incontinence. Although there is good evidence that colonic J-pouch reconstruction, side-to-end anastomosis, or a transverse coloplasty pouch (TCP) improves functional outcome, many surgeons still prefer straight coloanal anastomosis because it is technically easier and lacks the risk of pouch-associated complications. The present single-center study aimed to evaluate the practicability of TCPs in routine clinical practice as well as pouch-related complications. METHOD: All consecutive patients who underwent low anterior rectal resection with restoration of bowel continuity for cancer during the period September 2008 to June 2018 were included. A TCP in combination with a diverting ileostomy was defined as the hospital standard. The feasibility and safety of TCPs were assessed in a retrospective single-center study. RESULTS: A total of 397 patients were included in the study. A total of 328/397 patients underwent TCP construction (82.6%). Two pouch-related surgical complications occurred (0.6%); one case of pouch-related stenosis and one case of sutural insufficiency. Overall, leakage of the coloanal anastomosis was reported in 14.1% of patients with a TCP and in 18.8% of patients without a pouch (p=0.252). Diverting ileostomy was applied in 378/397 patients (95.2%). The 30-day mortality was 0.25%. CONCLUSION: The present study is by far the largest single-center experience with TCP construction for low rectal cancer resection. The study shows that a TCP is technically applicable in the vast majority of cases (82.6%). Pouch-associated surgical complications are sporadic events. In our opinion, the TCP can be considered an alternative to J-pouch construction after low anterior rectal resection.
