Selective shunts in selected older cirrhotic patients with variceal hemorrhage

Whereas portal systemic shunts pose significant problems in many patients, they have long been thought to have particular risks when undertaken in older cirrhotic patients, with devastating encephalopathy reportedly common in older patients undergoing nonselective shunt surgery. With advances in anesthesia management and perioperative monitoring and the advent of selective shunting, we postulated that both the operative and long-term outcomes might be improved. In this context, we reviewed our recent experience with selective shunts [distal splenorenal (DSRS) and small-diameter interposition portacaval grafts (IPCG)] in patients over the age of 60 years with variceal bleeding. Nineteen consecutive cirrhotic patients over 60 years of age undergoing elective or urgent selective shunt surgery for variceal hemorrhage since 1986 were identified. Sixteen patients underwent DSRS, and 3 underwent IPCG. The etiologies of the cirrhosis were multiple, with 12 of 19 classified as Child's B or C disease. There were no operative deaths, and all but one patient returned home following the surgery. No patient has had recurrent bleeding or required further surgery for portal hypertension-related problems. Three of 19 developed encephalopathy, and 4 of 19 died of liver failure within 1 year of surgery. Of the 14 patients still alive and well (mean postoperative survival: 44 months, range: 4 to 74 months), all remain free of encephalopathy and live independently. Based on this experience, it would appear that one can anticipate satisfactory short- and long-term outcomes after selective shunt surgery in selected patients with variceal bleeding over the age of 60 years. These patients with portal hypertension should not, therefore, be rejected for shunt surgery based on age alone.
