Using the special needle (22 Gauze, 17cm long, flexible needle) percutaneous transhepatic cholangiography were performed in 23 cases at Seoul National University Hospital during the period from July 1973 to August 1974. The results were as follows: 1. Successful cholangiograms are obtained in 20 cases among cases among the total of 23 cases. 2. Average attempts of puncture in successful case are 3. It was not necessary to puncture more than 6 times to visualize biliary tree in dilated biliary tree. 3. Lateral approach (midaxillary line and 8th or 9th intercostal space) was used. The advantage of this method was briefly discussed. 4. Over all complications are occured in 6 cases. 3 cases: transient fever 1 cases: bile leakage without peritonitis 1 cases: local peritonitis probably due to bile leakage 1 case: septicemia (the organism can not be detected even after blood culture)
