Objective: The aim of this study was to evaluate the experience of using endoscopic submucosal dissection (ESD), a technique considered as first-line of treatment, for the management of early neoplastic lesions (ENL), and subepithelial lesions (SEL) < 4 cms in size, in a tertiary-care, high-volume medical center in Mexico.
Method: Patients > 18 years-old, candidates to ESD with ENL and SMT, between January 2008 and October 2022 were included.
Results: ESD was performed in 246 patients (137 ENL and 109 SMT), 52.
