Risk stratification for stricture formation after endoscopic submucosal dissection for esophageal dysplasia.

ABSTRACT: We aimed to evaluate the demographic, clinical, procedural, and histopathologic factors associated with stricture development following esophageal endoscopic submucosal dissection (ESD). We conducted a retrospective cohort study of patients undergoing ESD for esophageal lesions from 2019 to 2024 at St. Michael's Hospital, in Toronto, Canada. The primary outcome was stricture formation, defined as a symptomatic luminal narrowing at the ESD site confirmed on follow-up endoscopy, requiring intervention. Strictures requiring dilation developed in 24% of patients, 85% of which were impassable with a standard gastroscope (9.9 mm diameter). Stricture rates increased with defect circumferential involvement: <50% (7.7%), 50%-74% (11.5%), 75%-89% (23.1%), and ≥90% (57.7%). Intraprocedural local tria
