Is early colonoscopy after admission for acute diverticular bleeding needed?

Urgent colonoscopy has been proposed for the diagnosis and management of acute colonic diverticular bleeding. Identification of active bleeding and nonbleeding stigmata facilitates diagnosis and endoscopic therapy, but it is unclear whether urgent colonoscopy after presentation increases the diagnostic yield. This study evaluated the association between timing of colonoscopy and diagnostic yield in patients admitted with acute colonic diverticular bleeding.


Patients admitted for hematochezia and receiving a diagnosis of diverticular hemorrhage were identified using the Mayo Clinic GI Bleeding Team and Emergency Room Admissions Databases for the years 1998-2000. Timing of colonoscopy was determined from the time of admission. Logistic regression analysis was used to assess whether the timing of colonoscopy was associated with an endoscopic finding of active bleeding or nonbleeding stigmata (or both).


A diagnosis of definitive or presumptive diverticular bleeding was made in 78 patients (39 men and 39 women, mean age 78 yr, range 49-96 yr). Twelve patients (15%) had active bleeding or stigmata. Colonoscopies were performed a mean of 18 +/- 11 h after admission. The association between a definitive diagnosis of acute diverticular bleeding and the timing of colonoscopy was not significant (p > 0.46).


No significant association is apparent between the timing of colonoscopy after admission and encountering active bleeding or nonbleeding stigmata. Based on these observations, urgent colonoscopy for these patients does not seem advantageous.
