Oral Omeprazole in Bleeding Peptic Ulcer

Overview

Find out if there is a significant difference between clinical outcome among the patients with bleeding peptic ulcer treated with oral omeprazole compared to those treated with intravenous omeprazole.

Globally, Peptic ulcer disease is the most common cause of upper gastrointestinal bleeding (UGIB), accounting for about 50% of cases. It remains a serious medical problem with significant morbidity and mortality (1, 2). However, in Egypt, bleeding peptic ulcer comes second to the bleeding varices in order of frequency (approximately 30%) (3). Over the past 20 years, mortality resulting from bleeding peptic ulcer significantly decreased through researches on primary endoscopic hemostasis, due to improvement in pre- and post-endoscopic management, as well as identification of patients at a risk of catastrophic events-for close observation and focused intensive management (4).However, the risk of patients with bleeding peptic ulcers significantly increased owing to the aging population with multiple comorbidities, as well as the increasing use of aspirin and non-steroidal anti-inflammatory drugs (5). Endoscopic therapy significantly reduces further bleeding, surgery, and mortality in patients with bleeding peptic ulcer and is now recommended as the first hemostatic modality for these patients. However, there is a high risk of peptic ulcer re-bleeding in 14-36% of patients, in spite of efficient endoscopic intervention (6). Intravenous proton pump inhibitors (PPIs) are effective as adjuvant pharmacotherapy in preventing re-bleeding in these patients (7). Gastric acid inhibits clot formation and promotes clot lyses and accordingly, disturbs hemostasis of ulcers in the stomach and duodenum (8). Therefore, reduction of gastric acid secretion can prevent ulcer re-bleeding. The use of high-dose intravenous PPIs is standard practice in the management of upper gastrointestinal bleeding (9). High dose IV PPI has faster adequate acid suppression effect (gastric acid PH \> 6) than high dose oral PPI . In addition, Compared to standard dose of oral PPI, high dose oral PPI has faster acid suppression (10, 11). However, the optimal route, dose, and duration of PPI therapy after endoscopic therapy of a bleeding peptic ulcer remain controversial. UGIB continues to represent a significant clinical and economic burden to society. Intravenous PPI therapy is more expensive than oral one. Therefore, the therapy has to be assessed from a cost-effectiveness perspective (12). Several controlled trials and meta-analyses have shown the comparable efficacy of IV and oral PPI in treating ulcers at high risk of re-bleeding after endoscopic therapy. However, further studies to confirm their results were recommended (13, 14). The investigators will evaluate and compare the efficacy and safety profile of oral PPI compared to IV PPI in preventing re-bleeding from peptic ulcers.
