Percutaneous transhepatic cholangioscopy facilitates proper diagnosis of the nature and extent of the biliary obstruction by direct endoscopic observation and concomitant sampling of the forceps biopsy. Malignant development in patient with choledochal cyst, which is often difficult to detect with the direct cholangiography, can be accurately revealed with this technique. Cholangioscopy may also be helpful in detecting the tumor in its early stage, the presence of which is inconclusive by direct cholagiography. Patients with hilar cholangiocarcinoma can be managed with bilobar hepaticdrainage via single percutaneous track with the aid of percutaneous transhepatic cholangioscopy, since the endoscope yields a fine directional control of the guide wire inserted through its working channel. Intraluminal laser therapy under cholangioscopic control is proved to be effective in recanalizing the obstruction. Future study will disclose the proper role of cholangioscopy in the diagnosis and the treatment of biliary malignancies.
