Abstract

During the past one and half year we performed ESWL therapy in 13 patients with common bile duct and intrahepatic duct stones, applying Lithostar-R (siemens co. West Germany) and analyzed their results. In 13patiets, 9 residual common bile duct stones and 7 intrahepatic duct stones were selected postoperatively. The sizeof stoens were ranged from 0.7cm to 3.5 cm in diameter, 2 stones were multiple and the remained 14 were single innumber. The visualization of stones were done with fluoroscopy after the injection of contrast media viacholangiographic T-tube or ERCP. ESWL were applied continuosly until stone disintegration was visible, or upto maximum number of 3500 discharge of shock wave. If not disintegrated upto 3500, patients were underwent second or third lithotripsy session with interval of one week. Our results showed that among 9 common bile duct stones, 4 were completely disintegrated and passed out spontaneously, but 3 partially fragmented and removed by the additional procedure. 2 were failed. Among 7 intrahepatic stones, 3 completely and 2 partially were succeeded. Onestone partially fragmented were retained without removal and other one were failed. Skin petechia in all patients were revealed on the entry port of shock wave, but no serous complication was not occured.
