Patients with co-morbidities have not only higher recurrent bleeding rates during the first 3 days but also higher delay recurrent bleeding after 3-day proton pump inhibitor (PPI) infusion than those without. More than 50% recurrent bleeding develops after 3-day PPI infusion among patients with end stage renal diseases. Although endoscopic treatment plus a 72-hour intravenous PPI infusion and followed by oral PPI has already been adopted as a standard treatment in peptic ulcer bleeding currently, several studies showed limited effectiveness of such treatment for high risk patients. The reasons may be because lesions of SRH were not completely faded after initial treatment including endoscopic hemostasis and intravenous PPI infusion. Thus, it is an important issue to improve such high recurrent bleeding risk for these patients.
