BackgroundProton pump inhibitors (PPIs) following endoscopic haemostasis reduce rebleeding rates in patients with high-risk acute non-variceal upper gastrointestinal bleeding. Many advocate the use of PPIs prior to endoscopy, although its incremental benefit is unproven.AimTo determine if providing PPIs before endoscopy reduces adverse gastrointestinal outcomes in acute non-variceal upper gastrointestinal bleeding patients.MethodsWe performed a retrospective review to identify patients presenting to two tertiary care centres with acute non-variceal upper gastrointestinal bleeding between 1999 and 2004. Subjects receiving PPI therapy before endoscopy were compared with those not receiving pre-endoscopic PPI therapy. The primary outcome measure was the development of any adverse bleeding outcome (rebleeding, surgery for control of bleeding, in-hospital mortality, readmission within 30 days for acute non-variceal upper gastrointestinal bleeding).Results385 patients were included in our study [132 (12 intravenous/120 po) pre-endoscopic PPI vs. 253 no pre-endoscopic PPI]. Patients receiving pre-endoscopic PPI therapy were significantly less likely to develop adverse outcomes compared with those not given pre-endoscopic PPIs (25% vs. 13%, P = 0.005). Rebleeding, upper gastrointestinal surgery, mortality and length of hospital stay were also significantly lower in patients receiving pre-endoscopic PPI.ConclusionsThe use of PPIs before endoscopy significantly reduces the risk of developing adverse gastrointestinal outcomes in patients with acute non-variceal upper gastrointestinal bleeding. Future studies are required to better characterize this relationship.
