BACKGROUNDGastro-Gastric Fistula is a rare but potentially serious complication of Roux-en-Y Gastric Bypass. Orogastric tube stapling is an adverse bariatric surgery iatrogenic complication that surgeons should be aware of and that has rarely been described. CLINICAL CASEA 51-year-old patient, operated in our University Hospital Center of a Gastric Bypass 3 years ago, presented on consultation with anemia and weight regain (BMI 36). An upper Gastrointestinal (GI) endoscopy showed a Gastro-Gastric Fistula and visualized the tip of a Faucher tube fixed in the blind pouch and an erosive ulceration on the gastrojejunal anastomosis. Multiple biopsies showed a low-grade dysplasia in the remnant stomach. A subtotal gastrectomy was performed with refashioning of the gastrojejunal anastomosis. DISCUSSIONAnemia and weight regain, with or without the association of marginal ulcers are the most common signs of Gastro-Gastric Fistula after Gastric Bypass (1-6%). Surgical treatment remains the standard of care and should be tailored to the size and location of the fistula and the status of the gastrojejunal anastomosis. Orogastric tube perioperative complications are rare occurrences during bariatric surgery and not reported at a later stage. They can be associated with significant morbidity. Prevention strategies must be taken and standardized to prevent such events. CONCLUSIONThe surgical option remains the standard of treatment and can be performed safely in Gastro-Gastric Fistula Type II. Orogastric tube accidental complications should be identified preferably perioperatively and measures of prevention should be implied to avoid such events.
