Gastrogastric fistulas occur in 3-6% of Roux en Y gastric bypass patients. They can cause abdominal pain, asymptomatic weight regain, and marginal ulcer formation. While surgical revision is the mainstay of treatment, we demonstrate a case of successful endoscopic suture closure of a large gastrogastric fistula causing persistent weight regain eight years after banded Roux en Y gastric bypass.
