Official title
Early Versus Elective Colonoscopy in the Management of Lower Gastrointestinal Bleeding
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Study hypothesis is that performing early colonoscopy in patients who present to the hospital with lower GI bleeding improves their outcome. Patients who are admitted with bleeding from their rectum and a negative endoscopic exam of the stomach and upper intestine are randomized (like flipping a coin) to receive a colonsoscopy either as an emergency (within 12 hours) or as a routine procedure (36 hours after admission). Patients are followed during their hospitalization to see if they have further bleeding, if they require blood transfusions, if they need other diagnostic tests, if they need surgery or other treatments, and how long they stay in the hospital.
