 Since July, 1975, percutaneous transhepatic drainage of the bile duct (PTCD) has been performed in 143 cases of obstructive jaundice. In order to have direct observation of an obstructing lesion, a drainage catheter is exchanged for a bigger step by step. And a cholangioscope is inserted into the drainage catheter, or directly to the fistula of the catheter and the inside of the bile duct is examined. We named this new technique percutaneous transhepatic cholangioscopy (PTCS).

 Various sized drainage catheters and slender cholangioscopes were deviced to make PTCS more useful examination. And at the time of PTCS, a biopsy of the lesion is also taken under cholangioscopic observation.Then PTCS enables us to differentiate whether obstructive jaundice is benign or malignant, to determine the extent of cancerous tumors and to detect multiple foci before operation. These are the three diagnostic advantages of PTCS.

 Furthermore PTCS was utilized as the therapeutic endoscopy. Transhepatic cholangjoscopic lithotomy was performed on a patient with bile duct stones or intrahepatic stones, for whom a laparotomy could not be applied.

 Among the 143 cases of PTCD,PTCS was performed in 43 cases and good results were obtained. We discussed its diagnostic and therapeutic advantages by presenting our retrospective cases.
