Reduction of surgical site infections after laparoscopic gastric bypass with circular stapled gastrojejunostomy.

Background: Circular stapled gastrojejunostomy (GJ) is favored by many surgeons during laparoscopic Roux-en-Y gastric bypass (LRYGB). However, it has been associated with higher rates of surgical site infection (SSI).

Objectives: To study the impact of introducing standard technical modifications (intervention) on the incidence of SSI after LRYGB with circular stapled GJ.
