Rectal membrane: an unusual complication following use of the circular stapling instrument for colorectal anastomosis.

Abstract

This is the first report of a rectal membrane forming at the site of a low end-to-end rectal anastomosis performed with the EEA circular gun. The diagnosis was made by Gastrografin enema that revealed disparity between the staple line diameter and the bowel lumen. The condition was treated easily by digital breakage of the membrane; there was a complete cure. A brief discussion of the etiology of anastomotic strictures and other gastrointestinal membranes follows.
