Predictors of utilization of early colonoscopy vs. radiography for severe lower intestinal bleeding

Logistical factors and the likelihood of a localized source of bleeding influence the performance of early colonoscopy for the evaluation of acute lower intestinal bleeding, whereas patients with clinical indicators of severe bleeding often undergo radiographic procedures. Because early colonoscopy may improve outcomes, further studies are needed to compare available strategies and to standardize the management of acute lower intestinal bleeding.
