Abstract
The predicative value of 15 pre- and peroperative parameters upon survival after portacaval shunt was analyzed in a retrospective investigation of 134 elective operations in humans. A multiple linear regression model was used. Survival was measured at 3 different points of time: 1 mo., 1 yr and 5 yr after the operation. Survival at 1 mo. was influenced by the parameters bilirubin/s and ascites only. Survival at 1 yr was influenced by albumin/s, sex, bilirubin/s, bromsulfophthalein, heart disease history and ascites. Survival at 5 yr was influenced by albumin/s, alkaline phosphatase/s, history of alcohol abuse and globulin/s. Prediction of survival after portacaval shunt is apparently an intricate process and considerable improvement of the Child criteria is possible.
