The sigmoid colon (colon sigmoideum) begins at the level of the left iliac crest and passes into the rectum at the level of the head of the sacrum. The length of the gut is from 15 to 67 cm (on average - 54 cm). Sigmoid colon forms 1-2 loops (bend) that adhere to the front of the left iliac bone and partially descend into the pelvic cavity. Sigmoid colon is intraperitoneal, has a mesentery. The presence of a mesentery causes significant mobility of the sigmoid colon.
