Diverticulitis occurs when small pouches of the colon wall become infected. A condition called Diverticulosis can often be diagnosed through colonoscopy or CT scan and is treated conservatively. However, when these small pouches become infected it can cause infections within the colon and abdominal cavity. Often surgery is needed to remove these pouches if they repeatedly become infected. Procedures for removal of these sections of the colon can be done through and open or laparoscopic procedure.
