ENDOSCOPIC SUBMUCOSAL DISSECTION WITH CIRCUMFERENTIAL INCISION VERSUS TUNNELING METHOD FOR TREATMENT OF SUPERFICIAL ESOPHAGEAL CANCER

BACKGROUND: Endoscopic submucosal dissection (ESD) of esophageal superficial neoplasm is associated with a high en bloc R0 resection rate and low recurrence. OBJECTIVE: We aim to compare the performance and clinical outcomes of ESD via ESD after circumferential incision (ESD-C) versus submucosal tunneling (ESD-T). METHODS: Single-center retrospective analysis of all consecutive patients who underwent ESD for superficial esophageal cancer,...
