Radiologic management of hepatolithiasis.
We describe the diagnostic workup and therapeutic management of patients with hepatolithiasis from the viewpoint of the interventional radiologist. The diagnosis is best established by direct cholangiography such as percutaneous transhepatic cholangiography or endoscopic retrograde cholangiography. We consider percutaneous transhepatic stone removal a highly successful, minimally invasive, and safe procedure. Access can be gained to the biliary system in almost 100% of patients and complete stone clearance through percutaneous techniques, including stone fragmentation, removal of stones and fragments by baskets, and dilatation of underlying strictures in more than 90%. The role of these radiologic techniques is discussed vis-à-vis endoscopic and surgical alternatives.
