Residual Intrahepatic Stones: Percutaneous Management with Balloon Dilatation and Stone Extraction
|
|

Abstract
|
|
|
Recurrent pyogenic cholangitis is frequently relapsed with residual intrahepatic stones and biliary strictures after surgical treatment.
Percutaneous removal of residual intrahepatic stones is an effective alternative for second operation which has a high mortality and morbidity.
However, the successful extraction of intrahepatic stones may be difficult because of a high frequency of associated biliary strictures.
We evaluated the effectiveness of percutaneous balloon dilatation in six patients who were difficult to extract residual intrahepatic stones due to biliary strictures.
Balloon dilatation using angioplasty balloon catheter was performed via a T-tube tract.
In four of six patients, balloon dilatation was successful and partially successful in two patients due to reccurence of stricture.
Stone extraction was complete in three patients, incomplete in two patients, and failed in one patient.
The reason of incomplete removal and failure were large sized stones and impacted stones in the intrahepatic ducts.
There was no complication.
In conclusion, percutaneous balloon dilatation is an effective procedure for extraction of residual intrahepatic stones associated with intrahepatic biliary strictures.
