Self-help inflatable balloon versus autologous skin-grafting surgery for preventing esophageal stricture after complete circular endoscopic submucosal dissection: a propensity score matching analysis.

Both the SHIB and ASGS had high efficacy and safety in preventing strictures in patients with mucosal defects no longer than 100 mm in length after esophageal cESD. The longitudinal length of ulceration > 60 mm was the independent factor for predicting stricture.
