Endoscopic management of GI fistulae with the over-the-scope clip system (with video)

Fistulae, generally those occurring after bariatric surgery, could be treated with the use of endoclips, covered self-expandable metal stents, and glue, although these options have several limitations, with many fistula recurrences. Stent migration, inadequate closure of the leak by clipping, or difficult stent removal occurred in more than half of the cases. (Source: Gastrointestinal Endoscopy)
