ABSTRACT
Subfractions of bilirubin in bile, obtained via biliary drainage tubes from 23 patients who had undergone radical surgery for bile duct cancer, were analysed by high‐performance liquid chromatography for 14 days after surgery. Five principal conjugated bilirubins were resolved: bilirubin diglucuronide (BDG); bilirubin monoglucuronide monoglucoside (BGG); bilirubin monoglucuronide monoxyloside (BGX); and two isomers of bilirubin monoglucuronide. After surgery, depression in concentration of BDG and elevation of BGG and BGX were found. These alterations were of higher magnitude in patients who had undergone hepatectomy, and especially prolonged in patients with hyperbilirubinaemia. These results suggest that the alteration in proportions of bilirubin conjugates might be a cause of hyperbilirubinaemia after hepatectomy.
