Sigmoid colon, a terminal section of the large intestine that connects the descending colon to the rectum; its function is to store fecal wastes until they are ready to leave the body. The sigmoid colon derives its name from the fact that it is curved in the form of an S (Greek sigma: Ï). Its size depends upon the amount of waste material in it, but when contracted its diameter is only about one inch (2.5 centimetres).
The sigmoid colon is towards the bottom right of the large intestine. Photograph: Alamy It is usually patients not doctors who balk at the sight of a medical instrument being unwrapped. But the flatus tube, used to treat a condition of the sigmoid colon, is one no surgeon relishes. The sigmoid is an S-shaped stretch of large bowel, about 40cm long, which leads up to the rectum. Its main function is to store faeces until it is ready to enter the rectum and be expelled through the anus, and it is the site of a variety of problems.
