Although the aim of colonic J-pouch to preserve reservoir function was physiologically achieved, the improvement in clinical defecatory function was not significant. Thus, further prospective studies are needed to confirm the functional superiority of colonic J-pouch anastomosis for stapled low colorectal anastomosis after low anterior resection.

Early postoperative defecatory function after low anterior resection is predictable from preoperative high pressure zone, maximum tolerable volume, and anal mucosal electrosensitivity.
