To evaluate during a 7 months period the efficacy, safety and accuracy of percutaneous transluminal forceps biopsy combined with transhepatic biliary drainage in patients with biliary stricture
Biological parameters of liver function, histopathology of specimens, comparison with others clinical and pathological data (imaging follow up, percutaneous biopsy, surgical biopsy, endoscopic biopsy) were recorded Comparison between pathological findings of surgery or endoscopy or percutaneous biopsy and specimens coming from biliary forceps biopsy follow up of the patient 12 months after biopsy Evaluation of complications, accuracy
