Abstract

In vitro, bile duct stones, mostly comprising calcium bilirubinate, are readily fragmented by extracorporeal shockwave lithotripsy (ESWL). In the case of intrahepatic stones, ESWL is effective if the stones float freely in the bile, but if the stones completely fill, or are impacted within, the hepatic duct or bile duct, attempts at fragmentation will end in failure. Three patients with intrahepatic stones were treated with ESWL, and effectively fragmented. The stone fragments passed out spontaneously through T-tube sinus tract, PTDC sinus tract and the sphincter of Oddi as shown in the second cholangiogram. No specific complication was noted in our experimental and clinical experience. We believe that ESWL for fragmentation of biliary stones is technically reliable. The problem of the passage of these fragmented stones is considered; if necessary, it can be overcome by endoscopic means.
