Trends in hospitalization mortality and timing of colonoscopy in patients with acute lower gastrointestinal bleeding

摘要

Background and study aims Current guidelines conditionally recommend performing early colonoscopy (EC) (< 24 hours) in patients admitted with acute lower gastrointestinal bleeding (LGIB). It remains unclear whether this practice is implemented widely. Therefore, we used the Nationwide Inpatient Sample to investigate trends for timing of colonoscopy in patients admitted with acute LGIB. We also assessed trend of hospitalization and mortality in patients with LGIB.
