Is Banding an Acceptable Treatment for Varices that have not Bled (Prophylaxis)?

Lay, C.-S., Tsai, Y.-T., Teg, C.-Y., Shyu, W.-S., Guo, W.S., Wu, K.-L. and Lo, K.-J. (1997) Endoscopic variceal ligation in prophylaxis of first variceal bleeding in ciorrhotic patients with high-risk esophageal varices. Hepatology; 25, 1346-1350. prophylactic EVL can decrease the incidence of first variceal bleeding and death over a period of 2 years in cirrhotic patients with high-risk esophageal varices. (Hepatology, 1997; 25, 1346-1350). To determine the efficacy of endoscopic variceal ligation (EVL) in prophylaxis on the rate of first esophageal variceal bleeding, we conducted a prospective, randomized trial in 126 cirrhotic patients with no history of previous upper gastrointestinal bleeding and with esophageal varices endoscopically judged to be at high risk of hemorrhage. The endpoints of the study were bleeding and death. Lifetable curves showed that prophylactic EVL significantly diminished the rate of variceal hemorrhage (12/62 [19%] vs. 38/64 [60%]; P 0.0001) and overall mortality (17/62 [28% vs. 37/64 [58% ]; P 0.0021). The 2 year cumulative bleeding rate was 19% (12/62) in the EVL group and 60% (38/64) in the control group. The 2 year cumulative mortality rate was 28% (17/62) in the EVL group and 58% (37/64) in the control group. Comparison of Kaplan-Meier estimates of the time to death of both groups showed significantly lower mortality in the ligation group (P=0.001). Patients undergoing EVL had few treatment failures and died mainly of hepatic failure. The lower risk in the EVL group was attributed to a rapid reduction of variceal size. Prophylactic EVL was more efficient in preventing first bleeding in patients with good condition (Child A) than in those with decompensated disease (Child B and C). We conclude that
