Results of a randomized trial of end-to-side portacaval shunt and distal splenorenal shunt in alcoholic liver disease and variceal bleeding.
Since 1976, we have compared the end-to-side portacaval shunt (PCS) with the distal splenorenal shunt (DSRS) in patients with alcoholic liver disease and recurrent variceal bleeding. Fifty-four patients were randomly assigned to receive either shunt procedure. There were 27 patients in each group and both groups were highly comparable in clinical and laboratory characteristics. Median follow-up was 31 mo in each group. Postoperative complications and operative mortality (7% after PCS, 12% after DSRS) were comparable. Spontaneous portasystemic encephalopathy developed in 32% of the patients at risk after PCS and in 39% after DSRS. Rebleeding from varices occurred in 4% of the patients after PCS and in 27% after DSRS. Cumulative survival was not significantly different between groups (5-yr survival: 31% after PCS, 43% after DSRS). We have failed to demonstrate superiority of DSRS in our patients with alcoholic liver disease with respect to postoperative encephalopathy or survival, and have experienced an unusually high rate of variceal rebleeding after DSRS.
