Abstract

PURPOSE
All procedures for the removal of retained intrahepatic stones were performed on inpatient basis. We evaluated the advantage of the procedures performed on inpatient basis compared with outpatient basis in terms of the success rate, causes of failure and the complication.
MATERIALS AND METHODS
Percutaneous removal of retained intrahepatic stones was performed in 58 patients through a T-tube tract on inpatient basis from April 1990 to December 4992. Stones were exclusively intrahepatic in 28 patients, whereas 30 patients had combined stones in common bile duct. Preshaped catheters, baskets, and balloon catheters were used to remove the stones and dilate the strictures of the ducts. Extracorporeal shock wave lithotripsy and choledochoscopy with electrohydraulic lithotripsy were used to crush the impacted stones.
RESULTS
The stones were completely removed in 34 (58.6%) of 58 patients and most of the stones were removed in 17 patients (29.3%). The overall success rate was 87.9%. The complications (cholangitis in 13% and pancreatitis in 0.8% per session) were found and successfully managed by appropriate care.
CONCLUSION
Better success rate could be achieved by more aggressive appraoch on inpatient basis when compared with previous reports on outpatient basis. We suggest that the procedures should be performed on inpatient basis especially in a case with severe strictures or impacted stones.
