Percutaneous transhepatic cholangioscopy (PTCS) is an useful technique to evaluate or treat biliary diseases, although PTCS is an invasive method for the patients. We used 5 F or 7 F of super fine cholangioscopy to treat two cases of choledocholithiasis after surgery without dilatation of drainage tract. We developed different types of bended sheath for supplement of lack of angle system in this cholangioscope. Furthermore, by using bended sheath, cholangioscopic view improved, because saline was injected at the same time via the sheath. We emphasize that super fine cholangioscope with bended sheath is a safe and useful modality for evaluation of biliary disease.
经皮经肝胆道镜检查（PTCS）是评估或治疗胆道疾病的一种有用技术，尽管PTCS对患者来说是一种侵入性方法。我们使用5F或7F超细胆道镜在未扩张引流通道的情况下治疗了2例术后胆总管结石患者。我们开发了不同类型的弯曲鞘，以补充这种胆道镜角度系统的不足。此外，通过使用弯曲鞘，胆道镜视野得到改善，因为通过鞘同时注入了生理盐水。我们强调，带有弯曲鞘的超细胆道镜是评估胆道疾病的一种安全且有用的方式。
