Analysis of endoscopic features for histologic discrepancies between biopsy and endoscopic submucosal dissection in gastric neoplasms: 10-year results

摘要

Background and aim: The histologic discrepancies between preoperative endoscopic forceps biopsy (EFB) and endoscopic submucosal dissection (ESD) specimens sometimes confuse the endoscope operator. This study aimed to analyze the limitation of the biopsy-based diagnosis before ESD and to evaluate which factors affect the discordant pathologic results between EFB and ESD.
