Prophylactic stenting to decrease the incidence of esophageal strictures after extensive endoscopic submucosal dissection: the first U.S. experience

Endoscopic submucosal dissection (ESD) allows en bloc resection of early esophageal adenocarcinomas and squamous cell carcinomas. However, this technique is not without shortcomings. When the resected area is ≥5 cm in length, strictures are common, and with circumferential resections (CRs), stricture formation is almost universal. 1 Bhatt A. Mehta N.A.

These strictures tend to be recalcitrant, and their treatment carries risks of adverse events. 1 Bhatt A. Mehta N.A. Stricture prevention after esophageal endoscopic submucosal dissection.
