Peroral tunable-dye laser lithotripsy of intrahepatic stones in oriental cholangitis.

This case report details the use of a pulsed tunable-dye laser lithotripter in the endoscopic management of recurrent intrahepatic stones in a patient with Oriental cholangitis. A 42-year-old Chinese man had a cholecystectomy and choledochoduodenostomy in 1980. Subsequently he had three episodes of recurrent cholangitis which responded to medical treatment. The patient presented in April 1989 with a fourth attack of cholangitis. Endoscopic retrograde cholangiopancreatography (ERCP) and ultrasound demonstrated a large mass of stones in the right intrahepatic ductal system. A flexible upper gastrointestinal endoscope was passed into the right hepatic duct via the choledochoduodenostomy. The stones were fragmented with a tunable-dye laser and the residual fragments were removed endoscopically.
