ARTICLE HIGHLIGHTS
Research background
Appropriate timing of colonoscopy for colonic diverticular hemorrhage is not well evidenced.
Research motivation
The motivation for this study is to investigate whether within 24 h is an appropriate timing for colonoscopy for colonic diverticular hemorrhage.
Research objectives
We aimed to compare the length of hospital stay for colonoscopy for colonic diverticular hemorrhage by dividing patients into two groups: early groups (within 24 h) and elective colonoscopy (after 24 h).
Research methods
A single-center retrospective study over 5 years compared the two groups using propensity score matching.
Research results
Early colonoscopy within 24 h did not significantly improve hospital stay.
Research conclusions
Early colonoscopy within 24 h for colonic diverticular hemorrhage may not improve length of hospital stay.
Research perspectives
Further research is needed to determine which patients really need early colonoscopy.
