Thirty-seven of these patients had had prior major operative therapy. In only three patients (8%) was shunt surgery successful, and there was a high incidence of rebleeding, other morbidity, and mortality. Of especial note are the serious consequences of simple splenectomy; splenomegaly and thrombycytopenia should rarely, if ever, be used as indication for splenectomy in portal hypertension. In 1977, the use of selective distal splenorenal shunt (DSRS) was begun at Emory in this population and a selective shunt has been possible in 24 of 29 patients (83%) who had had no prior operative therapy. Results have been excellent with a greater than 90% patency rate, long-term portal perfusion in all, no encephalopathy, and late rebleeding in one patient. Quantitative studies at 3-6 years show stability of liver function, significant decrease in spleen size, and rise in platelet count. However, long-term follow-up (>15 years) is required in PVT patients before definitive assessment can be obtained. A specific problem of the PVT patient is late shunt stenosis which requires close observation; dilatation of the shunt was performed in six of the 24 patients with a patent shunt. Poor results with non-shunt operative procedures in PVT were again documented. The proper role of endoscopic variceal sclerotherapy is not yet clear, but appears to be an excellent addition to the therapeutic options. In conclusion, for patients with a patent splenic vein, initial therapy should be a selective shunt; for patients without a patent splenic venous system, endoscopic sclerotherapy is the procedure of choice. E n XTRAHEPATIC PORTAL VEIN THROMBOSIS (PVT) in the noncirrhotic is a relatively uncommon cause of portal hypertension in this country. Effective management of bleeding varices in PVT

A prospective, randomized clinical trial with crossover for those failing therapy. The median follow-up was 61 months. A private, tertiary-referral university hospital. Seventy-two patients fulfilling inclusion criteria were drawn from a total of 420 patients treated during a 4.5-year interval. Endoscopic variceal sclerosis or distal splenorenal shunt. Survival was significantly (P = 0.02) improved in patients randomly assigned to receive sclerotherapy: 13 of these 37 (35%) patients failed sclerotherapy and required surgical rescue. A survival advantage (P = 0.01) was seen in patients with alcoholic cirrhosis who had this combined therapy; however, in patients with nonalcoholic cirrhosis, survival for those receiving sclerotherapy and surgical rescue was not significantly (P = 0.36) different from that of patients receiving distal splenorenal shunt. Control of variceal bleeding was significantly (P less than 0.001) better in the distal splenorenal shunt group (34 of 35 [97%] compared with 15 of 37 [41%] in the sclerotherapy group). Using death, uncontrolled rebleeding, or shunt thrombosis as the endpoints resulted in no significant difference between treatment groups. Hepatocyte function and portal perfusion were significantly better maintained in patients with alcoholic cirrhosis who were managed by sclerotherapy rather than shunt (P = 0.01 and P = 0.001, respectively). Endoscopic sclerotherapy with surgical rescue for uncontrolled bleeding is the optimum therapy for patients with alcoholic cirrhosis and variceal bleeding. Survival is similar in nonalcoholic patients treated with either distal splenorenal shunt or endoscopic sclerotherapy, but shunting provides better control of variceal bleeding.
