Management of a Gastrobronchial Fistula Presenting 5 Years After a One-Loop Gastric Bypass.

Anastomotic leaks and gastric fistulas are recognized complications after sleeve gastrectomy and Roux-en-Y gastric bypass. They are, however, almost unheard of following a one-anastomosis gastric bypass. A gastrobronchial fistula, an exceedingly rare complication after bariatric surgery, has to date never been described following a one-anastomosis gastric bypass. Furthermore, there is no consensus regarding the management of this challenging complication. In our case, we present a patient who was discovered to have a gastrobronchial fistula 5 years after a one anastomosis gastric bypass. After 2 failed attempts at endoscopic stent placement, the patient was successfully managed with a laparoscopic Roux-en-Y gastrojejunostomy over the fistula.
