The sigmoid colon is an S-shaped part of the colon that is in the left lower side of the abdomen, above the rectum. With age, this part of the colon or its attachments to the abdominal wall stretch out, allowing it to twist on itself, similar to the twisting of a long balloon, resulting in a volvulus. When this happens, the colon becomes blocked. In addition, the blood supply may be reduced, leading to injury or death of the tissues of that part of the colon. If not treated quickly, this can result in a perforation, a hole in the bowel through which stool and gas can spill into the abdomen. Perforations can be fatal without urgent intervention.Older age,chronic constipation,and living in a nursing home increase the risk of having sigmoid volvulus.
