Blind-pouch formation following lateral anastomosis.

Side-to-side anastomosis is an expedient method for reestablishing intestinal continuity after resection. However, this procedure may be followed by a unique complication, which does not occur after the end-to-end or end-to-side technique. Infrequently, saccular dilatation develops in the portion of the proximal segment of intestine that projects beyond the anastomotic stoma. This is not necessarily due to leaving in an excessively long blind end. A closed section no longer than an inch beyond the stoma may develop into a large dilatation. This complication is illustrated in the first case reported. Report of Cases Case 1. —A 63-year-old white man was admitted to the hospital on July 18, 1956.
