Peptic ulcer bleeding is a common disease, and recurrent bleeding is an independent risk factor leading to mortality. The appearance of stigmata of recent hemorrhage (SRH) indicates possible recurrence of peptic ulcer bleeding, for which the likelihood decreases over the course of 3-6 days. In addition to endoscopic evidences illustrating the SRH, patients with co-morbidities have a higher risk of recurrent bleeding.
