The use of peroral cholangioscopy to screen for neoplastic bile duct lesions in patients with bile duct stones (with videos) (cholangioscopy to screen for neoplastic lesion)

Abstract Background and study aims I-SCAN is a computed virtual chromoendoscopy (CVC) system designed to enhance surface and vascular patterns. In this study, we evaluated the usefulness of direct peroral cholangioscopy (POC) using I-SCAN compared with a conventional white-light image (WLI) to diagnose bile duct lesions. Patients and methods Patients with mucosal lesions in the bile duct detected during direct POC were enrolled prospectively. The quality of endoscopic visualization and the visual diagnosis were assessed using I-SCAN and WLI modes, respectively, during direct POC. Results A total of 20 patients (9 malignant and 11 benign lesions) underwent I-SCAN to evaluate lesions in the bile duct using direct POC. The quality of endoscopic visualization using direct POC with I-SCAN was significantly higher than that of WLI for surface structure (P = 0.04), surface microvascular architecture (P = 0.01), and margins (P = 0.02). Overall diagnostic accuracy of the visual diagnosis was not different between I-SCAN and WLI (90.0 % vs. 75.0 %; P = 0.20). Conclusion Direct POC using CVC by I-SCAN seems to be helpful for evaluating mucosal lesions of the bile duct, without the interference from bile.Clinical trial registration: UMIN000021009

Direct Peroral Cholangioscopy

At least 90% of stones are extracted after conventional endoscopic retrograde cholangiopancreatography. However, some cases are still difficult to manage completely. We describe some methods of removing difficult common bile duct stones through a single-operator cholangioscopy using SpyGlass system, direct peroral cholangioscopy, and temporary biliary stenting.
