Definition

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.

Alternative 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

Description

You'll receive general anesthesia at the time of your surgery. This will keep you asleep and pain-free.

The surgery can be performed laparoscopically or with open surgery. Depending on which surgery you have, the surgeon will make one or more cuts (incisions) in your belly.

Talk with your surgeon or nurse about how surgery will affect:

During the 2 weeks before your surgery:

The day before surgery:

On the day of surgery:

After the Procedure

You will be in the hospital for 3 to 7 days. You may have to stay longer if the colectomy was an emergency operation.

You may also need to stay longer if a large amount of your large intestine was removed or you develop problems.

By the second or third day, you will probably be able to drink clear liquids. Thicker fluids and then soft foods will be added as your bowel begins to work again.

Outlook (Prognosis)

Most people who have a large bowel resection recover fully. Even with a colostomy, most people are able to do the activities they were doing before their surgery. This includes most sports, travel, gardening, hiking, other outdoor activities, and most types of work.

If you have a long-term (chronic) condition, such as cancer, Crohn disease, or ulcerative colitis, you may need ongoing medical treatment.
