Ellen A Carraro, MD, Sabrena F Noria, MD, PhD. The Ohio State Wexner Medical Center

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.
