Endoscopic submucosal dissection for gastric neuroendocrine neoplasms – A multicentre retrospective study

#3665

Introduction: The optimal endoscopic management for Gastric Neuroendocrine Neoplasms (G-NENs) is yet to be determined, and data are limited in the literature.

Aim(s): We retrospectively reviewed patients with gastric NETs treated by Endoscopic Submucosal Dissection (ESD), followed by ESD follow-up, to evaluate its overall safety and efficacy in a western scenario.

Materials and methods: We retrospectively enrolled patients from 11 international tertiary referral centres. Baseline demographics, tumor characteristics and peri and post procedural adverse events were recorded. Outcomes such as ESD overall efficacy, R1 rate recurrence were considered. Due to the retrospective data collection, the follow up time was not standardized.
