Endoscopic submucosal tunnel dissection and endoscopic submucosal dissection for large superficial esophageal squamous cell neoplasm: efficacy and safety study to guide future practice

摘要

ESTD and ESD are currently the two primary treatment options for superficial esophageal squamous cell neoplasm (SESCN) in China. However, in larger cases, ESD proves to be technically challenging and time saving, whereas ESTD exhibits promising efficacy. This study aims to evaluate the efficacy and safety of these two techniques for large SESCN.
