Abstract
BACKGROUND: Gastrogastric fistula (GGF) occurs in 1-6% of patients who undergo Roux-en-Y gastric bypass (RYGB) for morbid obesity. The pathophysiology may be related to gastric ischemia, fistula, or ulcer. OBJECTIVES: The purposes of the study are to describe the principles of management and to review the literature of this uncommon complication. SETTING: The setting of this study is University Hospital, France. MATERIALS AND METHODS: We conducted a retrospective review of all patients' records with a diagnosis of GGF after RYGB between January 2004 and November 2014. RESULTS: During the study period, 1273 patients had RYGB for morbid obesity. Fifteen patients presented with a symptomatic GGF (1.18%). The average interval from surgery to presentation was 28 months (22-62). A history of marginal ulcer or anastomotic leak was present in nine patients (60%). The most common presentation was weight regain (80%), followed by pain (73.3%). Two types of fistulas were identified, an exclusively GGF (high) and a gastro-jejuno-gastric fistula (low). High GGF, frequently associated with dilatation of the gastric pouch, was treated by a sleeve of the pouch and sleeve resection of the remnant stomach (nine patients). Low GGF was treated with gastric resection coupled with a revision of the gastrojejunal anastomosis (six patients). All patients were treated laparoscopically with no conversion to laparotomy. The average length of postoperative hospital stay was 5.2 days (range 3-10). CONCLUSION: GGF after RYGB is a rare complication. Its pathophysiology remains unclear. Surgical management is the definitive treatment.
