<P> The sigmoid colon ( pelvic colon ) is the part of the large intestine that is closest to the rectum and anus . It forms a loop that averages about 35 - 40 cm in length . The loop is typically shaped like a Greek letter sigma ( ς ) or Latin letter S ( thus sigma + - oid ) . This part of the colon normally lies within the pelvis , but on account of its freedom of movement it is liable to be displaced into the abdominal cavity . </P>
