Prophylactic portosystemic shunt: a special indication

Ital J Surg Sci. 1983;13(3):175-8.

Abstract

Generally, when a splenectomy is performed to treat either a severe hypersplenism or another splenic affection in a cirrhotic patient with uncomplicated esophageal varices, the question arises whether to associate or not a prophylactic shunt. In fact, splenectomy alone does not lower the portal pressure and does not affect positively the esophageal varices. Because of this, 36% of these patients will eventually undergo a bleeding episode from varices. Furthermore, in the patients surviving the first bleeding, the occurrence of splenoportal thrombosis following splenectomy does prevent a therapeutic shunt to be performed. For this reason splenectomy with a complementary prophylactic shunt was performed in 24 patients. This operation, which showed 16% mortality rate, significantly prevented bleeding (0%). Furthermore in the treated patients, splenectomy has lowered the portal pressure. Encephalopathy occurred in 30% of cases, however the accuracy in the selection of patients together with a proper diet and medical treatment have avoided severe complications. The 5 year survival rate was 60%. Nevertheless, the indication to a prophylactic shunt must be limited to these particular cases.
