Diverticular disease is the general name for a common condition that causes small bulges (diverticula) or sacs to form in the wall of the large intestine (colon). Although the sacs can form anywhere in the colon, they are most common in the sigmoid coIon (part of the large intestine closest to the rectum).
The presence of diverticula without associated complications or problems. The condition can lead to more serious issues including diverticulitis, perforation (the formation of holes), stricture (a narrowing of the colon that does not easily let stool pass), fistulas, and bleeding.
An inflammatory condition of the colon thought to be caused by perforation of one of the sacs. Several secondary complications can result from a diverticulitis attack. When this occurs, it is called complicated diverticulitis.
The most commonly accepted theory ties diverticulosis to high pressure within the colon. This pressure causes weak areas of the colon wall to bulge out and form sacs. A diet low in fiber and high in red meat may also play a role. Currently, it is not well understood how these sacs become inflamed and cause diverticulitis.
Most patients with diverticulosis have no symptoms or complications. Some patients with diverticulitis experience lower abdominal pain and a fever or they may have rectal bleeding.
Diverticulosis often causes no symptoms. It may be diagnosed during screening tests such as a colonoscopy. A CT scan of the abdomen and pelvis may be used to confirm the diagnosis of diverticulitis.
Most people with diverticulosis have no symptoms. However, as a preventative measure, it is advised to eat a diet high in fiber, fruits, and vegetables, and to limit red meat.
Most cases of diverticulitis can be treated with antibiotics in pill form or intravenously (IV). Diverticulitis with an abscess may be treated with antibiotics with a drain placed under X-ray guidance.
Surgery for diverticular disease is indicated for the following:
Surgery for diverticular disease usually involves removal of the affected part of the colon. It may or may not involve a colostomy or ileostomy (intestine brought out through the abdominal wall to drain into a bag). A decision regarding the type of operation is made on a case-by-case basis.
