Complications at gastrojejunostomy after laparoscopic Roux-en-Y gastric bypass: comparison between 21- and 25-mm circular staplers.

Background: Complications involving the gastrojejunostomy (GJ) after laparoscopic Roux-en-Y gastric bypass (LRYGB) for morbid obesity frequently result in hospital readmission and additional procedures. The purpose of this study was to compare the complication rate of GJ performed with the 21- and 25-mm circular staplers.

Methods: We retrospectively reviewed the incidence of stricture, bleeding, ulcer, and leak at the GJ in 438 consecutive patients who had undergone LRYGB.
