Chiba needle percutaneous transhepatic cholangiography

Percutaneous transhepatic cholangiography with the Chiba University needle has been utilized in 30 patients. The ducts were successfully demonstrated in all 21 patients with obstructive jaundice. Sixty-seven percent of normal or stenosed ducts were visualized. No serious complications occurred and emergency post-procedural laparotomy was unnecessary. Our results reflect other reports. Percutaneous transhepatic cholangiography is an efficacious method of evaluating the hepatobiliary system.
