Failure to control bleeding and early rebleeding account for the high mortality associated with variceal hemorrhage in cirrhosis. We compared endoscopic sclerotherapy to terlipressin, a drug that effectively controls acute bleeding while reducing in-hospital mortality. This multicenter randomized controlled trial included 219 cirrhotic patients admitted for endoscopy-proven acute variceal bleeding and randomized to receive repeated injections of terlipressin during 6 days (n ؍ 105) or emergency sclerotherapy (n ؍ 114). Success was defined as obtaining control of bleeding (24-hour bleeding-free period during the first 48 hours) and lack of early rebleeding (any further bleeding from initial control to 5 days later) and survival during the study. Both groups were similar at inclusion. Failure rate for terlipressin was 33% and 32% for sclerotherapy (not significant [NS]). Early rebleeding was responsible for 43% and 44% of failures, respectively. This high efficacy was observed in both Child-Pugh class A ؉ B and Child-Pugh class C patients. Both treatments were similar regarding transfusion requirements, in-hospital stay, and 6-week mortality (26 vs. 19 patients). Side effects appeared in 20% of patients receiving terlipressin and in 30% of those on sclerotherapy (P ؍ .06); being serious in 4% and 7%, respectively (NS). In conclusion, terlipressin and sclerotherapy are equally highly effective therapies achieving the initial control of variceal bleeding and preventing early rebleeding. Both treatments are safe, but terlipressin is better tolerated. Therefore, terlipressin may represent a first-line treatment in acute variceal bleeding until the administration of elective therapy, especially in hospitals where a skilled endoscopist is not available 24 hours a day. (HEPATOLOGY 2000;32:471-476.)Variceal bleeding complicating cirrhosis results in a high mortality (24% to 35%), mainly determined by the impairment in liver function, the failure to control bleeding, and the development of early rebleeding. 1 The high frequency of early rebleeding (30% to 50%) 2 has led to the recommendation that treatments for variceal hemorrhage should be aimed, not only at arresting bleeding, but also at preventing early rebleeding. 3 Emergency endoscopic injection sclerotherapy (EIS) is widely considered as the best treatment for variceal bleeding. 3,4 However, EIS has limitations because of the difficulties in having an experienced endoscopist on a 24-hours-a-day basis and the risk of causing severe side effects, known to be more frequent following emergency than elective procedures. 5 It is doubtful that banding ligation is better than EIS in acute bleeding. 5 This has encouraged the search for pharmacologic alternatives overcoming these limitations. Recent large randomized controlled trials (RCTs) showed that terlipressin effectively controls variceal bleeding with a low rate of side-effects 6-12 even when used for an extended period. 13,14 Terlipressin has optimal applicability, does not require specialized staff or sophistic...
