Surgical management of extrahepatic portal hypertension and variceal bleeding.

Variceal bleeding remains an important complication in extrahepatic portal vein thrombosis (EPVT). As for portal hypertension due to other etiologies, an elective treatment to decrease the risk of subsequent rebleeding is warranted. The results of the Sugiura-Futagawa procedure (SP) in 38 patients with variceal bleeding secondary to EPVT are reported: 20 women and 18 men, with a mean age of 28 +/- 2 years (SEM). Thirty-seven patients were classified as Child-Pugh class A, and one patient as class B. In terms of diagnosis, 45% of patients had idiopathic EPVT, and 18% had associated hypercoagulability disorders; 52% of patients had associated splenic vein thrombosis. The SP was completed in two surgical stages in 18 patients and in one surgical stage in 14; 6 patients had only the abdominal stage. One patient had mild postoperative encephalopathy, and three patients rebled at long-term follow-up study. There were two operative deaths. Actuarial survival was 70% at 64 months. It is concluded that the SP is an excellent alternative for patients with variceal bleeding secondary to EPVT.
