Results in 671 patients treated for hepatobiliary or pancreatic malignancies at Nagoya University Hospital from April 1977 to April 1997. All patients underwent percutaneous biliary drainage (PTBD) and 385 had percutaneous transhepatic cholangioscopy (PTCS) with biopsies. The sensitivity values refer to the yield of the biopsies obtained during PTCS, using the histopathology obtained during later surgery or repeat biopsy or the clinical course as the gold standard. The overall sensitivity of PTCS was 82 percent.
