Role of the distal splenorenal shunt in management of variceal bleeding in Latin America.
In the early 1970s, we began to perform selective shunts on a regular basis for the treatment of portal hypertension. In a 15-year period, 177 patients (155 with liver cirrhosis) were treated with 3 kinds of selective shunts: the Warren shunt (128 patients) the end-to-end splenorenal shunt (29 patients), and the splenocaval shunt (20 patients). One hundred sixty-seven of the procedures were elective. Operative mortality was 14%, and survival for the Child's class A group was 75% at 1 year, 69% at 5 years, and 65% at 15 years. Incapacitating encephalopathy was observed in 7% of the patients, rebleeding in 6%, and shunt thrombosis in 6%. Postoperative portal vein alterations included reduced venous diameter (13%) and thrombosis (21%). Experience with the Warren shunt in schistosomiasis, a disease in which normal liver function is the rule in Latin American countries, is discussed. We believe that, when feasible, the selective shunts are the treatment of choice for portal hypertension in Latin American countries.
