The use of a self-assembling peptide gel for stricture prevention in the esophagus after endoscopic submucosal dissection: a U.S. multicenter prospective study (with video)

Post-operative stricture is serious common adverse event following extensive endoscopic submucosal dissection (ESD) in the esophagus. The self-assembling peptide (SA) gel has been shown to promote tissue healing and re-epithelialization. We aimed to evaluate the effect of the SAP gel for esophageal stricture prevention after ESD.
