Total colectomy and J‐pouch ileorectal anastomosis for obstructed tumours of the rectosigmoid junction

Background: Subtotal colectomy with ileosigmoid or ileorectal anastomosis is one of the standard procedures for obstructed tumours of the left colon. The lower the level of the anastomosis, the greater the number of bowel motions per day. The aim of the present study was to assess whether an ileal pouch–rectal anastomosis is associated with fewer bowel motions per day.
