Study Title and Description
Is early colonoscopy after CT-diagnosed diverticulitis still necessary?
Key Questions Addressed
3 | KQ 3: What are the benefits and harms of colonoscopy (or other colon imaging test) following an episode of acute diverticulitis? KQ 3a. What is the incidence of malignant and premalignant colon tumors found by colonoscopy, and what is the incidence of colon cancer mortality among patients undergoing screening? KQ 3b. What are the procedure-related and other harms of colonoscopy or CT colonography? KQ 3c. What is the frequency of inadequate imaging due to intolerance or technical feasibility? • Do the benefits and harms vary by patient characteristics, course of illness, or other factors? |
