About this study

The purpose of this study is to better understand why patients get infectious complications after colon or rectal surgery by identifying the bacteria present on the skin and within the gastrointestinal tract in both healthy volunteers undergoing a colonoscopy, and in patients undergoing colon and rectal surgery. By comparing the bacteria within these two groups, we will better understand the causes of postoperative infectious complications.
