Comparative evaluation of selective and nonselective peripheral portosystemic shunts for treatment of variceal hemorrhage.
There is currently available a variety of operative techniques that, by shunting of portal blood into the systemic circulation, decompress esophagogastric varices. Continued evaluation of when to employ a specific type of portosystemic shunt is indicated. This report compares experience with nonselective peripheral portosystemic shunts with selective distal splenorenal shunts. Twenty-nine patients were divided into two operative groups. All patients were operated on for variceal hemorrhage. The two patient groups were similar preoperatively in all parameters evaluated except that the patients having nonselective peripheral shunts had more ascites and four were operated on for acutely bleeding varices, whereas the selective shunt patients had minimal ascites and non were operated on for acute bleeding. Rebleeding rates, incidence of encephalopathy, and long-term survival were not significantly different between the two groups. Eight of 14 (57 percent) patients discharged from the hospital with selective distal splenorenal shunts were alive with a mean follow-up interval of 19 months. Eight of 11 (72 percent) patients discharged with nonselective peripheral shunts were alive with a mean follow-up interval of 34 months. These results suggest that if technical or clinical conditions preclude the performance of a selective distal splenorenal shunt, a nonselective peripheral shunt will produce comparable results and can be used with confidence.
