Core Tip	This study introduces the “5% plateau time” as a novel benchmark for determining the minimum necessary colonoscopy observation time in colonic diverticular bleeding (CDB). By analyzing 845 cases, we found that stigmata of recent hemorrhage (SRH) detection significantly diminished beyond 40 minutes, with stratified times of 40, 35, and 30 minutes, depending on the computed tomography findings. This time-based metric offers practical guidance for balancing the diagnostic yield and procedural burden, particularly in older adults. By identifying the minimum observation time necessary for adequate SRH detection, the 5% plateau time supports a safer and more consistent endoscopic management of CDB.
