摘要:
Peroral cholangioscopy (POC) is an important toolfor the management of a selected group of biliarydiseases. Because of its direct visualization, POC allowstargeted diagnostic and therapeutic procedures. POCcan be performed using a dedicated cholangioscopethat is advanced through the accessory channel of aduodenoscope or via the insertion of a small-diameterendoscope directly into the bile duct. POC was firstdescribed in the 1970s, but the use of earlier generationdevices was substantially limited by the cumbersomeequipment setup and high repair costs. For nearlyten years, several technical improvements, includingthe single-operator system, high-quality images, thedevelopment of dedicated accessories and the increasedsize of the working channel, have led to increaseddiagnostic accuracy, thus assisting in the differentiationof benign and malignant intraductal lesions, targetingbiopsies and the precise delineation of intraductaltumor spread before surgery. Furthermore, lithotripsyof difficult bile duct stones, ablative therapies forbiliary malignancies and direct biliary drainage can beperformed under POC control. Recent developmentsof new types of conventional POCs allow feasible, safeand effective procedures at reasonable costs. In thecurrent review, we provide an updated overview ofPOC, focusing our attention on the main current clinicalapplications and on areas for future research.
