The colon, or large intestine, is a muscular tube that begins at the end of the small intestine and runs to the rectum. The colon absorbs water from liquid stool that is delivered to it from the small intestine.
Indications, part 1Diverticula are out-pouchings of the wall of the colon. They are thought to be the result of a diet low in fiber. By the age of 60, over half of all Americans have colonic diverticula.
Indications, part 2In most cases, diverticula go unnoticed. However, in a small percentage of patients, diverticula can cause problems. The most common problem is diverticulitis, which occurs when a small, hard piece of stool is trapped in the opening of the diverticula. This leads to inflammation and death of the segment of colon containing the diverticula.
Indications, part 3Diverticula can also bleed and cause significant blood loss from the gastrointestinal tract. Vessels overlying a diverticula are stretched until they break, causing bleeding into the colon. Blood is usually passed in the stool.
IncisionTreament of diverticulitis and diverticular bleeding involves surgical removal of the segment of colon containing the diverticula. While the patient is deep alseep and pain free (general anesthesia), an incision is made in the midline of the abdomen.
ProcedureAfter the diseased area is removed, the healthy ends of the colon are sewn back together. Occasionally, especially in cases of diverticulitis, where there is significant inflammation, a colostomy is performed. After the inflammation has resided, the colostomy is removed and the healthy ends of the colon are sewn back together.

Most diverticula are located in the sigmoid colon
No diverticula are outpouchings mostly from the colon and polyps are inward growths
diverticula
Diverticula, which are little "weak spots" in the walls of the colon that often form little pouches, are often caused by a diet low in fiber. The lack of fiber means that the colon has to work harder to move contents along. This can often result in a weaker colon as a person ages, and thus diverticula can be formed in the walls of the sigmoid colon.
A diverticulum (plural diverticula) is an abnormal pouch found in the wall of a tubular organ. The esophagus and colon may have diverticula.
Diverticulosis develops when the diverticula form in the wall of the large intestine. The pouches don't cause symptoms, but they may become infected, and that is when the symptoms occur.
Diverticulosis
Diverticula
diverticula
diverticula is the plural of diverticulum.
Diverticulitis develops from diverticulosis, which involves the formation of pouches (diverticula) on the outside of the colon. Diverticulitis results if one of these diverticula becomes inflamed. In complicated diverticulitis, bacteria may subsequently infect the outside of the colon if an inflamed diverticula bursts open. Crohn's disease and Diverticulitis affecting the colon can occur at the same sites, at the same time, but usually in older individuals. When they occur in combination they can carry a worse prognosis than either disease in isolation. It is possible that diverticulitis may initiate inflammatory changes which resemble Crohn's disease histologically, but do not carry the same clinical implications of chronic inflammatory bowel disease.
"Diverticulum" is the singular of diverticula.
