Results The mean value of this isoenzyme in patients with malignant extrahepatic obstruction was significantly higher than that of patients with benign extrahepatic obstruction, as well as intrahepatic cholestasis and primary liver cancer.

Most cases of prehepatic hypertension in children resulted from extrahepatic obstruction of portal or splenic flow with normal function and structure of the liver. The prognosis was good.

结论：小儿肝前型门脉高压症主要是由于门静脉主干或脾静脉梗阻、栓塞而致门静脉压力增高，而肝脏功能、结构均正常，预后好。
