ENDOSCOPIC SUBMUCOSAL DISSECTION FOR EARLY GASTRIC CANCER: TECHNICAL FEASIBILITY, OPERATION TIME AND COMPLICATIONS FROM A LARGE CONSECUTIVE SERIES

Background:  Endoscopic mucosal resection (EMR) is a recognized treatment for early gastric cancer (EGC). One‐piece resection is considered to be a gold standard of EMR, as it provides accurate histological assessment and reduces the risk of local recurrence. Endoscopic submucosal dissection (ESD) is a new technique developed to obtain one‐piece resection even for large and ulcerative lesions. The present study aims to identify the technical feasibility, operation time and complications from a large consecutive series.
