Development and validation of a model to determine the risk of esophageal strictures after endoscopic submucosal dissection for esophageal neoplasms.

We developed a risk-scoring model based on factors including circumferential range, lesion location, depth of infiltration, and R0 resection. It stratified patients into low-, intermediate-, and high-risk groups for postoperative esophageal strictures development. This scoring model may have the potential to guide the management of patients after ESD in the future.
