Abstract
Percutaneous transhepatic removal of common bile duct stones was performed 54 times in 50 patients with a success rate of 93%. In all patients, a modified Dormia basket was inserted through a percutaneous transhepatic catheter, and the stones or fragments were advanced into the duodenum. All patients had contraindications to surgery or had undergone unsuccessful attempts at endoscopic retrograde cholangiopancreatography and sphincterotomy. Monooctanoin (25 patients) or methyl tertiary-butyl ether (four patients) was infused to reduce stone size or remove residual debris. The average time for complete stone removal was 8.6 days. Morbidity was 13% and mortality was 4%, results which compare favorably with those of surgery.
