A study found that patients with diverticulitis undergoing colonoscopy had a lower risk of colorectal cancer or advanced neoplasia compared to the screening population. However, those with complicated diverticulitis had a higher risk of colorectal cancer. The study analyzed data from over 4.5 million outpatient colonoscopies for screening and almost 92,000 for diverticulitis follow-up. Patients with diverticulitis were less likely to have colorectal cancer or advanced neoplasia, except for those with complicated diverticulitis. The study suggests that colonoscopy after complicated diverticulitis is necessary, but for patients with uncomplicated diverticulitis, it may not be needed if they are up-to-date with screening.
