[Effect of the Warren operation on hypersplenism].

The authors present their own comments on the effect of Warren shunt on hypersplenism. Hypersplenism is frequent complication in portal hypertension. The authors estimate its frequency on 64.7% of patients. Spleen size, thrombocyte count, WBC count, and esophageal endoscopy have been carried out prior to and following distal spleno-renal shunt. Surgery produced favourable effect in 70% of patients, i.e. a decrease of hypersplenism symptoms. An increase in blood platelet count may serve as a screening marker of anastomosis patency.
