Noticeable hyperbilirubinemia following major hepatectomy in patients with biliary tract carcinoma.

Abstract

Serum bilirubin concentrations were examined in patients who received hepatectomy for biliary tract carcinoma. They were divided into two groups according to the presence or absence of preoperative obstructive jaundice (POJ): the POJ group (n = 14) and non-POJ group (n = 10). The POJ group underwent percutaneous transhepatic drainage to delineate jaundice before definitive surgery. Total bilirubin concentration in the POJ group had increased at 1, 3, 5, 7 and 14 days after operation compared to the non-POJ group; the direct bilirubin level had increased at 1, 3, 5 and 7 days, and the indirect bilirubin level had increased at 1 and 3 days. Liver functional data before and 14 days after the operation were similar for the two groups. The incidence of cholangitis was higher in the POJ group than in the non-POJ group. Blood loss was greater in the POJ group than in the non-POJ group. The morbidity rate in the POJ group was higher than that in the non-POJ group. These results suggest that characteristic hyperbilirubinemia developed after major hepatectomy in patients with biliary tract carcinoma, and the bilirubin response is evoked by underlying preoperative biliary passing disturbance.
