Backgrounds/aims: Bleeding from gastroesophageal varices continues to be a life threatening complication of chronic liver diseases and portal hypertension. The purpose of this randomized prospective study is to compare the efficacy of octreotide administration and emergency injection sclerotherapy for the control of actively bleeding esophageal varices and prevention of early rebleeding in patients with cirrhosis.
Methodology: A total of 66 episodes of endoscopically proven active variceal bleeding in 52 patients were included in this study. Following admission to the hospital, the patients were resuscitated with blood and plasma, and fiberoptic endoscopy was performed within 2 hours. Thirty-six bleeds in 28 patients and 30 bleeds in 24 patients were randomized to endoscopic variceal sclerotherapy (1% polidocanol) and to octreotide infusion (at 50 micrograms/h for 12 hours following the initial 50 micrograms i.v. bolus), respectively.
Results: Bleeding was initially controlled within 6 hours in 75% of episodes by endoscopic variceal sclerotherapy and in 73.3 by octreotide infusion (P > 0.05). There were no significant differences between the 2 groups in early rebleeding (within 72 hours of randomization) (22% vs. 22.7%), blood transfusion (4.2 +/- 1.8 units vs. 4.8 +/- 2.9 units), or hospital mortality (3.6% vs. 3.3%). Treatment failed in 9 episodes (25%) in the sclerotherapy group and in 8 episodes (26.7%) in the octreotide group.
Conclusions: We consider that Octreotide would appear to be as effective as sclerotherapy in both the early control of variceal hemorrhage and in the prevention of early recurrent bleeding and should therefore be considered the treatment of choice in those centers where 24-hour endoscopy is not available. Furthermore, even in hospitals that do have a 24-hour endoscopy service there is good evidence that octreotide therapy should be commenced as soon as a patient enters hospital with a suspected variceal bleed to achieve rapid homeostasis. When initial hemostasis is achieved, elective endoscopic therapies can be undertaken with greater success.
