Core Tip	While colonoscopy within 24 h of hospital admission for colonic diverticular bleeding (CDB) is recommended, there is no evidence of improved rates of rebleeding within 30 d. This study aimed to evaluate outcomes of early colonoscopy for CDB. Results indicate that rebleeding significantly improved in patients with extravasation-positive computed tomography images taken within 4 h of the last hematochezia (P < 0.05). Clinicians are advised to utilize contrast-enhanced computed tomography within 4 h of active CDB to detect extravasation-positive cases. For these patients, colonoscopy is recommended within 24 h to reduce the risk of rebleeding.
