Endoscopic therapy for postoperative leaks and fistulae.

Endoscopic techniques for the treatment of postoperative fistulae and leaks are rapidly developing. Conventional surgical therapy for postsurgical leaks and fistulae is associated with significant morbidity and mortality. Novel endoscopic therapies have demonstrated safety, despite the inherent challenges of intervention in this patient population, and are steadily building evidence for efficacy relative to surgical management. The article examines endoscopic therapy for leaks and fistulae after esophageal, gastric, bariatric, colonic, and pancreaticobiliary surgery.
