Percutaneous transhepatic cholangiography. Report of a technique.

Percutaneous transhepatic cholangiography was carried out in 30 patients with jaundice of unknown cause. The examination was successful in 24, and the correct diagnosis was established before operation in 23. Among the specialized radiographic procedures useful in the differential diagnosis of jaundice, the percutaneous transhepatic cholangiogram is simple and reliable. It will distinguish intrahepatic from extrahepatic biliary obstruction. In benign structures, it can give a good anatomical and pathological definition of the problem which faces the surgeon. Occasionally, it may make operation unnecessary. Serious complications are hemorrhage and bile peritonitis. The incidence is low and by careful management they can be avoided.
