Clinical Trials

Comparison of Surgery and Medicine on the Impact of Diverticulitis (COSMID) Trial

Lead Researcher: Fergal Fleming

The COSMID trial compares two different ways to treat people with diverticulitis. One way is to have surgery to remove the part of the colon that is affected by diverticulitis. The other way is to take medicine and make changes to your diet and lifestyle. The doctors in this trial want to see which way of treating diverticulitis is better for people's quality of life. They are also looking at how well each treatment works at preventing future problems from diverticulitis. Some people will be randomly assigned to one of the two treatments. Others will be able to choose which treatment they want. All of the people in the study will be asked to complete surveys about their quality of life and how well their treatment is working. You are eligible to enroll if you are 18 years or older and had at least one episode of diverticulitis confirmed by CT scan and a colonoscopy.
