Is portal-systemic shunt worthwhile in Child's class C cirrhosis? Long-term results of emergency shunt in 94 patients with bleeding varices.

RESUMO

A prospective evaluation was conducted of 94 unselected patients ("all comers") with biopsy-proven Child's class C cirrhosis (93% alcoholic) and endoscopically proven acutely bleeding esophageal varices who underwent emergency portacaval shunt (EPCS) (85% side-to-side, 15% end-to-side) within 8 hours of initial contact (mean, 6.1 hours) during the past 12 years. Follow-up has been 100% and includes all patients for at least 1 year, and 61 patients (65%) for 5 to 12 years. Incidence of serious risk factors on initial contact was: ascites, 97%; jaundice, 86%; portal-systemic encephalopathy including past history, 71%; severe muscle wasting, 96%; alcohol ingestion within 7 days, 66%; delirium tremens, 16%; serum albumin, less than or equal to 2.5 g/dL 76%; indocyanine green dye retention greater than or equal to 50% in 45 minutes, 66%; serum glutamic-oxaloacetic transaminase greater than or equal to 100 units/L, 60%; hyperdynamic cardiac output greater than or equal to 6 L/minute, 98%. Mean Child's point score was 13.7 out of a maximum of 15. EPCS reduced mean corrected free portal pressure from 286 to 23 mm saline, and permanently controlled variceal bleeding in every patient. Of the 94 patients, 74 (80%) left the hospital alive and 68 (72%) survived 1 year. Five-year actuarial survival rate is 64%. Hepatic failure was the main cause of death during initial hospitalization as well as during follow-up, when it was related to continued alcoholism. Portal-systemic encephalopathy, which was present on initial contact in 55% of patients, occurred at some time during follow-up in 18.7%, but was recurrent and required dietary protein restriction in only 9%, all of whom had resumed alcoholism. The low incidence of portal-systemic encephalopathy was attributable to the lifelong program of follow-up with regular dietary counseling and continued emphasis on both protein restriction to 60 g/day and abstinence from alcohol. Abstinence was sustained in 69%, liver function improved in 82%, general health was judged excellent or good in 73%, and Child's risk class converted to class B in 73% and class A in 21%. Excluding retirees because of age, 42% were gainfully employed or engaged in full-time housekeeping. Long-term shunt patency was documented in 100% of survivors by yearly angiography or Doppler ultrasonography. It is concluded that EPCS within 8 hours of initial contact permanently controls variceal hemorrhage and results in prolonged survival and a life of acceptable quality in many alcoholic cirrhotic patients in Child's class C.(ABSTRACT TRUNCATED AT 400 WORDS)
