A prospective, open-labeled, and randomized trial for assessing safety and clinical utility of gastric biopsies during emergency gastroscopy for patients with bleeding gastric ulcers.

Patients undergoing biopsy during EG did not exhibit an increased risk of re-bleeding compared with those who did not undergo a biopsy. An early biopsy facilitates an early pathologic diagnosis, early clinical intervention, safe discharge of low-risk patients, and improved outcomes in high-risk patients.
