1 Introduction Endoscopic submucosal dissection (ESD) is a minimally invasive method for complete resection of early esophageal lesions [1, 2]. Although ESD mitigates surgical trauma and improves long-term prognosis, it also poses potential complications such as bleeding, perforation and postoperative esophageal stricture [3]. Studies report a 90% incidence of esophageal stricture when the mucosal defect covers more than three-fourths of the esophageal circumference [4-6].
