Abstract
During the past 5 1/2 yr, 30 consecutive and unselected patients who bled from esophageal varices underwent distal lienorenal shunt surgery. Eight deaths occurred in the immediate postoperative period. Three of 9 emergency patients died because of continued bleeding and, of the 5 elective patients who died, 4 were largely the result of technical problems encountered at surgery. In the immediate postoperative period variceal bleeding recurred in 5 of 8 emergency patients despite shunt patency. This did not occur in the elective group. Shunt blockage was relatively common compared to that following conventional portasystemic shunt surgery, being documented in 5 of the 24 patients in whom patency was assessed. No clinical, biochemical or histological criteria were identified as predictors of outcome. In particular, the presence of preoperative ascites gave no indication of postoperative problems. If ascites developed in the immediate postoperative period, it was a major management problem in 50% of the patients. The distal lienorenal shunt has a high perioperative mortality, is commonly complicated by shunt thrombosis and, in the emergency situation, often fails to control bleeding. The technical difficulties encountered at surgery appear largely responsible for the early morbidity and mortality.
