Sigmoid colon.
Medical expert of the article
Last reviewed: 07.07.2025
The sigmoid colon (colon sigmoideum) begins at the level of the left iliac crest and passes into the rectum at the level of the sacral promontory. The length of the intestine ranges from 15 to 67 cm (on average - 54 cm). The sigmoid colon forms 1-2 loops (bends) that are adjacent to the wing of the left ilium in front and partially descend into the pelvic cavity. The sigmoid colon is located intraperitoneally and has a mesentery. The presence of the mesentery causes significant mobility of the sigmoid colon.
