Alternate Names : Ascending colectomy, Descending colectomy, Transverse colectomy, Right hemicolectomy, Left hemicolectomy, Hand assisted bowel surgery, Low anterior resection, Sigmoid colectomy, Subtotal colectomy, Proctocolectomy, Colon resection, Laparoscopic colectomy, Colectomy - partial, Abdominal perineal resection


Definition

Large bowel resection is surgery to remove all or part of your large bowel. This surgery is also called colectomy. Removal of the entire colon and rectum is called a proctocolectomy. The large bowel is also called the large intestine or colon.

The large bowel connects the small intestine to the anus. Normally, stool passes through the large bowel before leaving the body through the anus.

Overview & Description

You will receive general anesthesia right before your surgery. This will make you unconscious and unable to feel pain. You will have either laparoscopic or open surgery.

Depending on what type you have, your surgeon will make 1 or more incisions (cuts) in your belly.

In a laparoscopic colectomy, the surgeon uses a camera to see inside your belly and small instruments to remove the part of your large bowel. You will have 3 to 5 small cuts in your lower belly. The surgeon passes the medical instruments through these cuts.

  • You may also have a cut of about 2 to 3 inches if your surgeon needs to put a hand inside your belly.
  • Your belly will be filled with gas to expand it. This makes the area easier to see and work in.
  • Your surgeon will remove the diseased part of your large bowel.
  • The surgeon will then sew the healthy ends of the bowel back together. This is called resecting.
  • Then your cuts will be closed with stitches.

For open colectomy, your surgeon will make 6-inch cut in your lower belly.

  • The surgeon will find the part of your colon that is diseased.
  • The surgeon will put clamps on both ends of this part to close it off.
  • Then the surgeon will remove the diseased part.
  • If there is enough healthy large intestine left, your surgeon will sew or staple the healthy ends back together. Most patients have this done.
  • If you do not have enough healthy large intestine to reconnect, your surgeon will make an opening called a stoma through the skin of your belly. Your large intestine will be attached to the outer wall of your belly. Stool will go through the stoma into a drainage bag outside your body. This is called a colostomy.

In most cases, the colostomy is short-term. It can be closed with another operation later. But, if a large part of your bowel is removed, the colostomy may be permanent.

Your surgeon may also look at lymph nodes and other organs, and may remove some of them.

Colectomy surgery usually takes between 1 and 4 hours.
