Sigmoid diverticula - Definition

Ask a question


The sigmoid diverticula are small sacs, or hernias, which occur mainly in the sigmoid colon, the last part of the large intestine. They are formed at an area of weakness in the wall and are not responsible for any symptoms in the absence of complications. However, in cases of inflammation of these diverticula, often due to a stagnation of feces and a proliferation of germs around them, they can cause diverticulitis, responsible for pain in the left of the abdomen and fever. Diverticula are often discovered during a colonoscopy.
