Risk factor of acute hemorrhagic rectal ulcer

Abstract

This study aimed to elucidate the clinical features of patients with acute rectal hemorrhagic ulcer (AHRU) and risk factors for rebleeding. We retrospectively evaluated 79 patients, which were endoscopically diagnosed with AHRU at our hospital from January 2009 to April 2020. The mean age of patients was 79.8 years. The performance status 3 and 4 were 74 (93.7%). The patients with hypertension and cardiovascular disease accounted for about half. Rebleeding was observed in 17 (21.5%), and we compared rebleeding group (n=17) and non-rebleeding group (n=62) using univariate analysis. There was no significant difference inpatient clinical features, but ulcers with active bleeding was observed more frequency in case of hemostasis perfomoed with hemostatic forceps in univariate analysis (p=0.011). Therefore, the hemostasis method may require reconsideration.
