This paper analyzes experience with 106 patients treated primarily with DSRS during a ten year period. Operative mortality was 5% of cases. Shunt patency was evaluated by postoperative angiography in 70 patients. A shunt thrombosis and a recanalization of the splenic vein were noted in a patient who had a Britton's operation resulting in a side-to-side shunt. In the other 31 cases, shunt patency was indirectly confirmed by the absence of varices at postoperative or long-term endoscopic examination. At postoperative check, esophageal varices had disappeared in only 19% of patients. However, this rose to 60% at long-term check-up. Ten patients bled from varices in the postoperative period (9%). During the follow-up period, no patient bled from varices, while five patients bled from gastroduodenal lesions (5%). During the postoperative period, 52% of cases had ascites. In the long-term, ascites developed in only 15% of cases and was well controlled by standard medical treatment. Analysis of the actuarial curve showed a 5-year survival rate of 63%. During the follow-up period, 17% of patients experienced at least one episode of acute encephalopathy. Chronic encephalopathy appeared in 14% of cases: ten patients suffered a mild form (10%) and four (4%) a moderate form. No patient had severe chronic encephalopathy. DSRS is effective as treatment of portal hypertension with a low long-term morbidity despite a more troublesome early postoperative period.
