Core Tip
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 mi
