The causes of postoperative prolongation of jaundice were investigated in 18 patients who showed prolonged jaundice after definitive operation for biliary atresia. Following results were obtained: 1) Some patients had abnormal high levels of serum transaminase, alkaline phosphatase, and γ-GTP preoperatively. 2) Portal pressure at the time of definitive operation was comparatively high, more than 200mmH_2O, in most of the patients whose serum bilirubin level was more than 5mg/dl. On the other hand, the portal pressure in patients whose bilirubin level was less than 5mg/dl, was mostly under 200mmH_2O. There was, however, no significant difference between them and non-interic patients. 3) Although it is not the leading factor, ascending cholangitis is one of the significant cause of nrolnncfped jaundice. 4) Almost all of the patients who showed prolonged jaundice showed a tendency toward elevation of the γ-globulin and/or TTT and/or γ-GTP in the two or three months period after the operation. When these tendencies are seen postoperatively, the patients should be treated more carefully.
