Role of Omeprazole in the Prevention and Treatment of Postendoscopic Esophageal Variceal Sclerotherapy Induced Ulcerations

Clinical Question

Will omeprazole treatment prevent ulcer formation or speed the healing of ulcers induced by endoscopic sclerotherapy for esophageal varices?

Clinical Bottom Line

  1. There is no statistically significant difference in the risk of ulcer development or healing of ulcers with or without the use of omeprazole in patients undergoing endoscopic sclerotherapy for esophageal ulcers.

The Evidence

Omeprazole no. (%) Placebo p-value*
Esophageal ulcer development 16 (76%) 18 (78%) NSS**
Total number of ulcers/group 51 55 NSS
Mean number of ulcers/patient 2.43 2.39 NSS
Number of ulcers healing within 7 days 19 (37%) 26 (47%) NSS
Healing within 7 - 14 days 30 (59%) 24 (45%) NSS
Healing > 14 days 2 (4%) 5 (8%) NSS
Esophageal strictures 2 1 NSS


Comments

  1. Valid according to the JAMA User's guide on Therapy articles.
  2. This was a small study (N=47), only three lost to follow-up, but all patients were accounted for.
  3. No confidence intervals were provided, although these are probably not a necessity since none of the differences between groups were statistically significant by the Chi-square and one-sided Student's t-test.
  4. Despite being a small study, this is fair evidence that treating patients with omeprazole who've undergone endoscopic variceal sclerosis does not result in any added benefit. Given the cost of omeprazole, this reviewer cannot recommend it's routine use in these situations.
