Overtube balloon-assisted direct peroral cholangioscopy (POC) using an ultraslim endoscope may be an effective alternative to the conventional mother-baby endoscope system. A total of 14 patients with biliary diseases underwent direct POC with an ultraslim endoscope. The endoscope was successfully advanced into the bile duct in all 14 patients (100 %). The success rate of the POC was 92.9 % (13/14) on the criterion of reaching the hilum or stricture site. Endoscopic biopsy was performed in six patients. Cystic duct or residual common bile duct stones were removed successfully under direct endoscopic visualization in three patients. A diagnosis of malignant or indeterminate bile duct stricture was changed to benign lesion or stricture or normal biliary mucosa in eight of ten patients. Procedure-related biliary tract infection occurred in one patient. This series demonstrated that direct POC using an ultraslim endoscope is useful for both diagnosis and treatment.
使用超细内镜的经口胆管直接镜检查术（POC）可能是传统子母镜系统的有效替代方法。共有 14 名胆道疾病患者接受了超细内镜的直接 POC。在所有 14 名患者（100%）中，内镜均成功进入胆管。根据到达肝门或狭窄部位的标准，POC 的成功率为 92.9%（13/14）。6 名患者进行了内镜活检。3 名患者在直接内镜下可视化下成功取出胆囊管或残余胆总管结石。10 名患者中的 8 名恶性或不确定的胆管狭窄的诊断被更改为良性病变或狭窄或正常的胆管黏膜。1 名患者发生与操作相关的胆道感染。本系列表明，使用超细内镜的直接 POC 可用于诊断和治疗。
