gastrogastric fistula
An abnormal connection between the gastric pouch and excluded stomach remnant in gastric bypass patients.
Full Definition
A gastrogastric fistula is a serious complication following Roux-en-Y gastric bypass where an abnormal passage develops between the small gastric pouch and the larger excluded stomach remnant. This connection allows food to bypass the restrictive mechanism, leading to weight regain and potential nutritional issues. The condition typically requires surgical intervention and may present with symptoms including weight gain plateau, increased appetite, and gastrointestinal discomfort. Diagnosis is usually confirmed through upper gastrointestinal contrast studies.
Usage
Usage note: Often abbreviated as GG fistula in clinical documentation.
