Abstract

BACKGROUND: Peptic ulcer rebleeding (PUR) usually occurs within three days following endoscopic hemostasis. However, recent data have increasingly suggested delayed rebleeding.OBJECTIVE: To better characterize the timing of PUR (Forrest Ia to IIb) following initially successful endoscopic hemostasis.METHODS: An exhaustive literature search (1989 to 2013), with cross-referencing, was performed to identify pertinent randomized controlled trial (RCT) arms. Patients receiving high-dose proton pump inhibitor (PPI) infusion following successful modern-day endoscopic hemostasis were included. A sensitivity analysis included any patients receiving PPI doses >40 mg daily. The main outcome measure was 30-day rebleeding, while weighted mean averages at t = three, seven, 14 and 28 to 30 days are also reported.RESULTS: Of 756 citations, six RCTs were included (561 patients; 58.5% to 89.5% male; 55.3 to 67.5 years of age). Among patients receiving high-dose PPI (five RCTs [393 patients]), 11.5% (95% CI 8.4% to 14.7%) experienced rebleeding, 55.6% (95% CI 41.1% to 70.1%) rebled within three days, 20% (95% CI 8.3% to 31.7%) between four and seven days, 17.8% (95% CI 6.6% to 28.9%) at eight to 14 days, and 6.7% (95% CI 0% to 14%) at 15 to 28 to 30 days. Using the relaxed lower PPI dosing threshold, similar respective rates were 14.4% (95% CI 11.5% to 17.3%) overall, with interval rates of 39.5% (95% CI 28.9% to 50.15%), 34.6% (95% CI 24.2% to 44.9%), 19.7% (95% CI 11% to 28.4%) and 6.2% (95% CI 0.95% to 11.5%). Qualitative review of patient characteristics, limited by small sample size, possible bias and study heterogeneity, suggested increased patient comorbidity and postendoscopic use of lower PPI dosing may predict delayed rebleeding.CONCLUSION: In patients with high-risk PUR undergoing successful endoscopic hemostasis, most rebled within three days, with many experiencing later rebleeding. Additional research is needed to better predict such an outcome.
