Appendectomy—Open Surgery

Click here to view an animated version of this procedure.

Definition

An appendectomy is the removal of the appendix. The appendix is a small blind-ended tube that is attached to the large intestine.

Reasons for Procedure

An appendectomy is most often done as an emergency operation to treat appendicitis . Appendicitis is inflammation of the appendix. It can be caused by an infection or obstruction.

Possible Complications

Complications are rare but no procedure is completely free of risk. If you are planning to have an appendectomy, your doctor will review a list of possible complications which may include:

  • Bleeding
  • Damage to other organs
  • Infection
  • Reaction to anesthesia

Some risk factors that make complications more likely include:

What to Expect
Prior to Procedure

Your doctor may do the following:

  • Blood and urine tests
  • CT scan —a type of x-ray that uses a computer to make pictures of the inside of the body
  • Physical exam
  • Ultrasound —a test that uses sound waves to find the appendix and other organs
  • X-rays —a test that uses radiation to take a picture of the inside the body

Antibiotics will be started right away. Since appendicitis is an emergency condition, surgery is almost always done right away.

Anesthesia

General anesthesia will be used. You will be asleep with a temporary breathing tube in place.

Description of the Procedure

A short incision will be made in the right lower abdomen. The doctor will be able to see the appendix through this cut. The appendix will be detached from surrounding tissue. The surgeon will stop any bleeding from blood vessels. The appendix will then be tied off and cut out. The incisions will then be closed with stitches or staples.

If the appendix has ruptured, a warm water solution mixed with antibiotics will be used to wash out the inside of the abdomen. A catheter (tube) will then be placed to drain any fluid that builds up. Sometimes, with a rupture, the surgeon will only close the muscle layers and leave the skin open. The open skin wound will then be packed with a moist gauze dressing.

After Procedure

The removed tissue is examined by a pathologist.

How Long Will It Take?

1-2 hours

Will It Hurt?

Anesthesia prevents pain during surgery. You may be given medicine to manage any pain.

Average Hospital Stay

You may be in the hospital for 0-3 days. If the appendix has ruptured, expect to stay for several days or more than a week.

Post-procedure Care
At the Hospital
  • If your appendix ruptured, drainage tubes will be removed after a few days.
  • You will be asked to get out of bed about six hours after surgery.
At Home

Recovery takes about 4-6 weeks. When you return home, do the following to help ensure a smooth recovery:

  • Be sure to follow your doctor's instructions .
  • Ask your doctor about when it is safe to shower, bathe, or soak in water.
  • Do not exercise or do heavy lifting for one or more weeks as directed by your doctor.
  • Gradually increase activities as approved by your doctor.
  • Keep the incision area clean and dry.
  • Rest and take it easy for 1-2 weeks.
  • Wash your hands before changing the dressing.
  • You may be given antibiotics to fight infection. Take all the medications ordered, even if you start to feel better.
  • You may resume your normal preoperative diet as soon as possible.
Call Your Doctor

After you leave the hospital, contact your doctor if any of the following occurs:

  • Cough, shortness of breath, chest pain, or severe nausea or vomiting
  • Fainting or dizziness
  • Increased abdominal pain
  • Passing blood in the stool
