Large bowel resection is surgery to remove all or part of your large bowel. This surgery is also called colectomy. 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.
You will get general anesthesia before your surgery. This will make you sleep and keep you pain-free. The surgery can be performed laparoscopically or with open surgery.
Depending on what type of procedure you have, your surgeon will make one or more cuts in your belly.
With laparoscopic colectomy, the surgeon uses a tiny camera to see inside your belly and small instruments to remove part of your large bowel. You will have three to five small cuts in your lower belly. The surgeon passes the medical instruments through these cuts.
For open colectomy, your surgeon will make a 6- to 8-inch cut in your lower belly.
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.

You will be in the hospital for 3 to 7 days. You may have to stay longer if your colectomy was an emergency operation.
You may also need to stay longer if a large amount of your small intestine was removed or you develop any complications. By the second or third day, you will probably be able to drink clear liquids. Your doctor or nurse will slowly add thicker fluids and then soft foods as your bowel begins to work again.
Most people who have a large bowel resection recover fully. Even with a colostomy, most people are able to do most activities they were doing before their surgery. This includes most sports, travel, gardening, hiking, and other outdoor activities, and most types of work.
If you have a long-term (chronic) condition, such as cancer, Crohn's disease, or ulcerative colitis, you may need ongoing medical treatment.
