Classification, surgical management and outcomes of patients with gastrogastric fistula after Roux-En-Y gastric bypass

Weight regain and epigastric pain with or without associated MU are the most common signs of GGF. Combining upper gastrointestinal endoscopy and contrast study is the best method to confirm the diagnosis. Surgical treatment should be tailored to both GGF location and status of the gastrojejunostomy. Based on its anatomic location, GGF classification could serve as a working basis to compare different surgical approaches.
