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

Anastomotic complications were recognized in 50 (11.4%) of 438 patients who had undergone LRYGB in which the GJ was performed using circular staplers, including 11 (17.2%) with the 21-mm and 39 (10.2%) with the 25-mm stapler. The rate of anastomotic stricture was significantly lower using the 25-mm circular stapler.
