Colonic pouch anastomosis improves the quality of life of patients with rectal cancer > 7 cm from the anal margin. But whether colonic pouch anastomosis can reduce the incidence of rectal resection syndrome in patients with low rectal cancer (within 6 cm of the anal ring) is unknown.
Identify the role of colonic pouch for low rectal cancer.
Compare postoperative and oncological outcomes and bowel function of straight and colonic pouch anal anastomoses after resection of low rectal cancer.
We conducted a retrospective study of 72 patients with low rectal cancer who underwent sphincter-saving procedures with either straight or colonic pouch anastomoses. Then, we explored the technical safety, functional results, and oncological safety of colonic pouch anastomosis after low and ultralow rectal resection by comparing with straight anastomoses.
There were no significant differences in postoperative and oncological outcomes between the colonic pouch and straight anastomosis groups. However, patients with colonic pouch construction had lower postoperative low anterior resection syndrome scores than the straight anastomosis group, suggesting better bowel function.
Colonic pouch anastomosis is a safe and effective alternative to straight anastomosis after low and ultralow rectal resection. Moreover, colonic pouch anastomosis may provide better postoperative functional outcomes.
Future prospective randomized trials are required to validate the findings of this study.
