Anterior Resection and Sigmoid Colectomy
The left side of the large bowel (illustration right) is removed and the colon joined to the rectum with staples or stitches. This can be done by either laparoscopic (keyhole) or open surgery. As with any bowel surgery with a join there is a small chance of leakage from the join after the procedure which is between 5-12% depending on how low the join is. Where there is a higher risk of leakage (Operations with a low join or significant previous surgery) a temporary Ileostomy will be made. This is usually only needed for a period of about six weeks.
