Abstract

The present retrospective study evaluated the role of inpatient lower gastrointestinal (LGI) endoscopy in adults with acute lower gastrointestinal bleeding between 2014 and 2018. The primary outcome was 6‑month readmission due to recurrent bleeding, analyzed using propensity score matching (PSM). Of the 567 patients, 120 (21.2%) underwent inpatient LGI endoscopy, with overall readmission in 57 (10.1%). In the univariate analysis, inpatient LGI endoscopy was not associated with a significant difference in readmission rates. Patients receiving antiplatelet and/or anticoagulant therapy demonstrated higher numerical readmission rates; however, this association did not reach statistical significance. Prior to PSM, endoscopy patients showed higher transfusion and CT angiography rates, indicating selection bias toward higher‑risk cases. After PSM, no significant difference in readmission was observed between groups. Colonoscopy had a diagnostic yield of 36% with 19% therapeutic intervention, while flexible sigmoidoscopy was less effective. Findings suggest inpatient LGI endoscopy should be selectively applied, with guidelines refined to target high‑risk patients.
