Percutaneous management of bile duct stones

This article presents a review of the interventional radiological procedures in the percutaneous management of the bile duct stones through T-tube or transhepatic tracts. Interventional stone removal techniques mainly include extraction through the T-tube tract with baskets or forceps and expulsion into the duodenum by means of baskets or balloon catheters with the dilatation of the sphincter of Oddi. Fragmentation or size reduction of the stone, dilatation of the strictures and cholangioscopic assistance can facilitate the procedures.
