Management of gastrogastric fistula after laparoscopic Roux-en-Y gastric bypass

MU/GGF should be considered in the differential diagnosis of all postoperative gastric bypass patients who present with abdominal pain. In our series, GGF was always associated with MU. Early diagnosis of GGF can be successfully treated with PPI therapy. Smaller-diameter tracts that do not resolve with medical therapy may respond to endoscopic therapy. Large-caliber fistula are less likely to respond to medical or endoscopic therapy but can be managed laparoscopically.
