Effectiveness of early colonoscopy in patients with colonic diverticular hemorrhage: A single-center retrospective cohort study

Response to “Interpreting colonoscopy timing in patients with colonic diverticular bleeding”

“…2 Thus, we conducted a similar study including comprehensive clinical data (n = 557) and identified merely 0.54% (95% confidence interval 0.18-1.57) cases requiring early colonoscopy because of shock from rebleeding. 3 No cases resulted in IVR, surgery, or death; therefore, the likelihood of interventional necessity following severe rebleeding is relatively low. 3 Previous studies have demonstrated that early colonoscopy had worse rebleeding outcomes.…”
