Abstract
Peroral cholagioscopy is a good procedure that permits direct visualization of the biliary tree and target biopsies of lesions. However, peroral cholangioscopy with a mother- baby system requires two experienced endoscopists, and the procedure remains time consuming and expensive and the apparatus is easily broken. Therefore, an easier technique to get direct visual examination of the biliary tree is needed. Direct peroral cholangioscopy (direct POC) with using an ultra-slim upper endoscope was performed in two patients after endoscopic stone removal for diagnosing their biliary stricture. One patient had wire-guided direct POC performed and the patient was diagnosed benign biliary stricture on the proximal CBD after forcep biopsy. Another patient had overtube-assisted direct POC performed and that patient was found to have a polypoid lesion at the bifurcation. Future advances in endoscope development, as well as specifically designed accessories, are expected to increase its clinical utility. Korean J Gastrointest Endosc 2007;35: 373-377)
