Background
/Aims: The aim of this study was to evaluate the efficacy of high definition (HD) i-SCAN for colorectal polyp detection in screening colonoscopy.
Methods
We retrospectively analyzed the records of 501 patients who had undergone screening colonoscopy performed by three endoscopists with either HD i-SCAN (n=149) or standard white light (n=352) from January 2, 2014 through June 30, 2014. Patient information and inter-endoscopist variation as well as polyp number, endoscopic findings, and pathologic characteristics were reviewed.
Results
The detection rates of colorectal and neoplastic polyps were significantly higher using HD i-SCAN than standard white light colonoscopy (52% vs. 38.1%, p=0.004 for colorectal polyps; and 37.2% vs. 27.9%, p=0.041 for neoplastic polyps). Analysis of endoscopic findings revealed no difference in detected polyp size between HD i-SCAN and standard white light colonoscopy (4.59±2.35 mm vs. 4.82±2.81 mm, p=0.739), but non-protruding polyps were more commonly detected by i-SCAN than by standard white light colonoscopy (24.6% vs. 13.5%, p=0.007).
Conclusions
Colonoscopy using HD i-SCAN had a significantly higher detection rate of colorectal polyps, including neoplastic polyps, because of improved sensitivity for detecting non-protruding lesions.

Intralesional Steroid Injection to Prevent Stricture after Near-Circumferential Endosopic Submucosal Dissection for Superficial Esophageal Cancer: Wook Jin Lee, Hwoon-Yong Jung, Do Hoon Kim, Jeong Hoon Lee, Kee Don Choi, Ho June Song, Gin Hyug Lee, Jin-Ho Kim; Clin Endosc 2013;46(6):643-646.

Abstract PDF PubReader ePub

Stricture frequently occurs after endoscopic submucosal dissection (ESD) for superficial esophageal carcinoma with near- or whole-circumferential mucosal defects, and post-ESD stricture is difficult to treat and usually requires multiple sessions of endoscopic balloon dilatation. Intralesional steroid injection has previously been used to prevent stricture; however, there have been few experiences with this method after near- or whole-circumferential ESD. We present a case of a single session of intralesional steroid injection performed immediately after near-circumferential ESD to prevent post-ESD stricture. After a follow-up period of 6 months, the patient showed good outcome without dysphagia.
