Core Tip
Core Tip: This article interprets the 5% plateau time model for colonoscopy in colonic diverticular bleeding and emphasizes that a 40-minute observation period should be treated as a flexible minimum floor rather than a rigid rule. By framing observation time as a “time-to-yield” curve, we propose practical strategies for computed tomography-stratified targets, a 20-25 minutes quality checkpoint, individualized shortening in high-risk patients and structured documentation. These suggestions aim to improve time efficiency and operational quality in the management of acute lower gastrointestinal bleeding.
