[Preoperative assessment of risk for gastroenterological operations in patients with hepatic cirrhosis].

In order to devise an easy and available method to assess the surgical risk of cirrhotic patients, we reviewed 52 cirrhotic patients who underwent gastroenterological operations at Tokyo Kosei Nenkin Hospital between 1968 and 1982, by means of multivariant discriminant analysis. Utilizing presence of ascites, serum albumin, ICG R15, prothrombin time and platelet count, we estimated the surgical risk as Risk Score. Furthermore, our method predicted short-term survival of other 150 cirrhotic patients who underwent gastroenterological operations at the First Surgical Department The University of Tokyo between 1968 and 1985. We conclude that our method is easily available, and that cirrhotic patients with Risk Score less than or equal to 2.5 tolerate all the gastroenterological operations except hepatic major resection, and that those with Risk Score of residual liver less than or equal to 2.5 tolerate well hepatic major resection.
