Effect of Second-look Endoscopy on Peptic Ulcer Rebleeding in Patients With Early Resumption of Antiplatelet Agents

Summary

OBJECTIVES: Up to 15% of patients with peptic ulcer bleeding will develop rebleeding, mainly in those with ulcers of higher-risk stigmata (i.e. Forrest class Ia to IIb). Randomized trials show that second-look endoscopy is effective in reducing rebleeding rate. However, whether to withhold aspirin or other anti-platelet agents (for the treatment of established cardiovascular or cerebrovascular diseases) remains controversial. Studies have shown that although continuation of anti-platelet agents reduces mortality rate due to reduced cardiovascular and cerebrovascular events, there is a marginal increase in rebleeding risk. HYPOTHESIS: We hypothesize that continuation of aspirin or other anti-platelet agents coupled with second-look endoscopy could reduce the rebleeding rate without increasing the risk of thromboembolic events in high-risk patients.
