[Factors in long-term survival after total portal systemic shunting: a multiple regression analysis].

163 patients with portal hypertension underwent portal systemic shunting at PUMC hospital during the time of 1970's. There were 98 cases had central spleno-renal shunts. 38 had portacaval shunts and 27 had meso-caval shunts. The live function in this group are A-40%, B-55% and C-5%. The totaled operative mortality was 11.0%, and the totaled 5 years survival was 59.5%. The analysis reveals that: (1) The long-term survival and the patient's life quality were significant influenced by liver function and the type of shunting; (2) The mortality of emergency operation was significant higher than elective shunting surgery (30.0% vs 4.6%); (3) The cephalopathy and rebleeding rate were correlated with the type of shunting, liver function and the diameter of shunt; (4) The patient with A or B liver function could accept either elective or emergency operation, but emergency surgery should be carefully chosen for. The mortality was higher than 80% in emergency shunting for the patient with liver function C.
