Very Low Stapling of the Anal Canal in Laparoscopic Ileal Pouch-Anal Anastomosis

Performing a double-stapled ileal pouch-anal anastomosis requires very low stapling of the anal canal. However, this laparoscopic procedure is often difficult to perform. We describe here a transanal method of everting the rectum, which allows easier transection under visual control and a sufficiently low anastomosis. Once the entire colon and rectum have been dissected out at laparoscopy, a plastic tube is introduced per anum and advanced into the mid sigmoid. The rectum is then divided at the level of the rectosigmoid junction by an endostapler, which also attaches the plastic tube to the rectum. The colon specimen is removed by a small incision at the chosen stoma site. Gentle traction on the plastic tube at the perineum everts the rectal tube. The anal canal is then transected at the desired level relative to the dentate line.
