Percutaneous transhepatic gallstone removal by needle tract.
A percutaneous transhepatic cholangiogram tract was used to visualize a large stone in the common duct; following the tract's dilation, the stone was crushed and partially removed. Fragments were flushed and also passed spontaneously into the duodenum. The approach described offers a feasible alternative to surgery.
