[Percutaneous cholangiography: Chiba method, a diagnostic advance]

Employing percutaneous transhepatic cholangiography by CHIBA method in 15 patients, it was possible to visualize biliary system in 93.3% of the cases. The radiologic diagnostic of KLATSKIN tumor was observed in 2 cases, 4 cases of carcinoma of the papila of VATER, 1 case of carcinoma of the terminal choledochus, 1 case of intrahepatic neoplasia, 1 case of stenosis secondary to choledocal, trauma, and in another it was damaged by subcapsular hepatic leakage of contrast. The complications were minor. In 5 cases the patients had biliary colic at the time of the exam. In 2 cases, signals of baeteremia occurred in the day following the exam, and in 4 cases there was a small subcapsular hepatic leakage of contrast. In one case it was encountered hematoma under the capsule of the liver, during surgery. The diagnosis was confirmed at surgery in 12 cases. We concluded that the simplicity of the technic, its low cost and its diagnostic, accuracy have made it extremely useful.
