Tu1582 Utility of Ultrathin Endoscope for Endoscopic Submucosal Dissection of Esophageal Carcinoma

Abstract

Endoscopic submucosal dissection (ESD) is increasingly utilized for resection of a superficial esophageal carcinoma. However, because the esophagus wall is thin and the lumen narrow, ESD for an esophageal carcinoma is difficult, especially early during the procedure until the tip of endoscope can slip under the dissected mucosa. We examined use of an ultrathin endoscope for approaching the narrow submucosal space of the esophagus during all or a portion of the ESD procedure to make the early part of the process easier and safer.
