Insights
Urgent colonoscopy for colonic diverticular bleeding (CDB) significantly reduces in-hospital death and improves endoscopic hemostasis rates compared to elective procedures. This intervention is crucial for managing severe CDB cases effectively.
Area of Science:
- Gastroenterology
- Clinical Medicine
- Endoscopy
Background:
- Colonic diverticular bleeding (CDB) can be severe despite a generally good prognosis with conservative therapy.
- The effectiveness of urgent colonoscopy and factors influencing CDB prognosis remain incompletely understood.
Purpose of the Study:
- To evaluate the efficacy of urgent colonoscopy in managing CDB.
- To identify clinical risk factors associated with unfavorable outcomes, including in-hospital mortality.
Main Methods:
- Utilized the Diagnosis Procedure Combination database for patient data.
- Employed propensity score matching to compare urgent versus elective colonoscopy groups.
- Analyzed endoscopic hemostasis rates, in-hospital death rates, and length of hospital stay.
- Conducted logistic regression to identify clinical factors impacting CDB events.
Main Results:
- Urgent colonoscopy demonstrated a lower in-hospital death rate (0.35% vs. 0.58%) and higher endoscopic hemostasis rate (3.0% vs. 1.7%) compared to elective colonoscopy.
- Hospitalization was shorter with urgent colonoscopy (8 vs. 9 days).
- Multivariate analysis confirmed urgent colonoscopy's benefit in reducing in-hospital death (OR=0.67) and increasing endoscopic hemostasis (OR=1.84).
Conclusions:
- Urgent colonoscopy appears effective in identifying bleeding sites and reducing mortality in CDB patients.
- The timing and necessity of urgent colonoscopy should be individualized based on patient condition and clinical presentation.
Background And Aim:
Although colonic diverticular bleeding (CDB) is considered to have good prognosis with conservative therapy, some cases are severe. The efficacy of urgent colonoscopy for CDB and clinical factors affecting CDB prognosis are unclear. This study aimed to evaluate the efficacy of urgent colonoscopy for CDB and identify risk factors for unfavorable events, including in-hospital death during admission, owing to CDB.
Methods:
We collected CDB patients' data using the Diagnosis Procedure Combination database system. We divided eligible patients into urgent and elective colonoscopy groups using propensity score matching and compared endoscopic hemostasis and in-hospital death rates and length of hospital stay. We also conducted logistic regression analysis to identify clinical factors affecting CBD clinical events, including in-hospital death, a relatively rare CDB complication.
Results:
Urgent colonoscopy reduced the in-hospital death rate (0.35% vs 0.58%, P = 0.033) and increased the endoscopic hemostasis rate (3.0% vs 1.7%, P < 0.0001) compared with elective colonoscopy. Length of hospitalization was shorter in the urgent than in the elective colonoscopy group (8 vs 9 days, P < 0.0001). Multivariate analysis also revealed that urgent colonoscopy reduced in-hospital death (odds ratio = 0.67, 95% confidence interval: 0.46-0.97, P = 0.036) and increased endoscopic hemostasis (odds ratio = 1.84, 95% confidence interval: 1.53-2.22, P < 0.0001).
Conclusion:
Urgent colonoscopy for CDB may facilitate identification of the bleeding site and reduce in-hospital death. The necessity and appropriate timing of urgent colonoscopy should be considered based on patients' condition.
