Right Hemicolectomy
The right colon, and depending on the location of the diseased tissue, parts of the transverse (middle) colon may be taken out to remove the affected areas. The ends of the colon are put back together surgically to reconstitute normal bowel function.

Left Hemicolectomy
The left colon may be taken out to remove the affected areas. The ends of the colon are put back together surgically to reconstitute normal bowel function.

Sigmoid Colectomy
All or part of the sigmoid colon, the part of the colon closest to the rectum and anus, may be taken out to remove the affected areas. The left side of the colon is reconnected to the rectum to reconstitute normal bowel function.

Low Anterior Resection
The upper part of the rectum may be taken out to remove the affected areas. The colon is then connected to the part of the rectum that is still left.

Abdominal Perineal Resection
The sigmoid (the lower part of the colon), rectum and anus are removed. A permanent colostomy is put in place.

Total Colectomy
The entire colon is removed. The small intestine is then connected to the rectum.
Studies show that there are benefits for patients having minimally invasive colorectal surgery, which can be completed through small incisions, instead of open surgery with much larger incisions. Ask your surgeon if this is a good option for you. | |||||
