[Evaluation of transparietal hepatic cholangiography in the diagnosis of cholestatic syndrome]. / Valoración de la colangiografía transparietohepática en el diagnóstico del síndrome colestásico.

ABSTRACT

Three hundred and thirty-two percutaneous cholangiograms were done in 313 patients. The etiology was benign in 137 cases and malignant in 152 instances. The level of obstruction was correctly localized in 97.8% of cases. The total sensitivity was 88.5% and specificity 95.9%. Positive predictive value 95.4% and negative predictive value 89.6%. Major complications occurred in 3.3% of cases. Complications occurred more frequently when the bile ducts were dilated. They were not related to the number of attempts to puncture ther biliary tree or the experience of the physician.
