Appendectomy

Appendix removal; Surgery - appendectomy; Appendicitis - appendectomy

An appendectomy is surgery to remove the appendix.

Description

The appendix is a small, finger-shaped organ that branches off from the first part of the large intestine (colon). When it becomes swollen (inflamed) or infected, the condition is called appendicitis. When you have appendicitis, your appendix may need to be removed. An appendix that has a hole in it can leak and infect the entire abdomen area. This can be life threatening.

Appendectomy is done using either:

  • Spinal anesthesia -- Medicine is put into your lower back to make you numb below your waist. You will also get medicine to make you sleepy.
  • General anesthesia -- You will be asleep and not feel any pain during the surgery.

Your surgeon may make a small cut in the lower right side of your belly area and remove the appendix.

Your appendix can also be removed using small surgical cuts and a camera. This is called a laparoscopic appendectomy.

If your appendix broke open or a pocket of infection (abscess) formed, your abdomen may be washed out during surgery. A small tube may be left in the belly area to help drain out fluids or pus.

Why the Procedure Is Performed

An appendectomy is done for appendicitis. The condition can be hard to diagnose, especially in children, older people, and women of childbearing age.

Most often, the first symptom is pain around your belly button:

  • The pain may be mild at first, but it becomes sharp and severe.
  • The pain often moves into your right lower abdomen and becomes more focused in this area.

Other symptoms include:

  • Diarrhea or constipation
  • Fever (usually not very high)
  • Nausea and vomiting
  • Reduced appetite

If you have symptoms of appendicitis, seek medical help right away. Do not use heating pads, enemas, laxatives, or other home treatments to try to relieve symptoms.

Your health care provider will examine your abdomen and may perform a rectal exam and pelvic exam. Other tests may be done:

  • Blood tests, including a white blood cell (WBC) count, may be done to check for infection.
  • Your provider may order a CT scan or ultrasound to determine if the appendix is the cause of the problem since other illnesses can cause the same or similar symptoms.

The goal is to remove an infected appendix before it breaks open (ruptures). After reviewing your symptoms and the results of the physical exam and medical tests, your surgeon will decide whether you need surgery.

Risks

Risks of anesthesia and surgery in general include:

  • Reactions to medicines
  • Problems breathing
  • Bleeding, blood clots, or infection

Risks of an appendectomy after a ruptured appendix include:

  • Buildup of pus (abscess), which may need draining and antibiotics
  • Infection of the incision

After the Procedure

Most people leave the hospital in 1 to 2 days after surgery. You can go back to your normal activities within a few weeks after leaving the hospital though it may take several weeks to get back to your normal energy level.

If you had laparoscopic surgery, you will likely recover quickly. Recovery is slower and more complicated if your appendix has broken open or an abscess has formed.

Living without an appendix causes no known health problems.

    Appendicitis - Animation

    You may never have given much thought to your appendix, the little pouch that's attached to the top of your large intestine. And you wouldn't have much reason to think about it, because it doesn't seem to do anything. But if your appendix were to become swollen and inflamed, it would probably move to the front of your mind. The pain of appendicitis can make you quickly, and unpleasantly, familiar with this organ. You can get appendicitis if your appendix becomes blocked. That blockage could be from feces, a foreign object, or, in rare cases, a tumor. When your appendix is blocked up, bacteria that normally live inside it start multiplying like crazy, and cause an infection. If you've got appendicitis you'll usually have pain that's centered around the area of your belly button. At first the pain may be minor, but it can get very severe and will usually drift downward to the bottom right part of your abdomen. You may also have nausea, vomiting, diarrhea or constipation, and a low fever. Your pain may let up for a time. This relief can be misleading, though. Just when you think you're getting better, your appendix may have actually burst. If that's the case, the pain will get start to get more and more intense. To diagnose appendicitis, your doctor will ask about your symptoms and press on your abdomen, which will feel very tender. You may need imaging tests, such as a CT scan or ultrasound of your abdomen, so the doctor can see if the problem is with your appendix. If you have appendicitis, the number one way to treat it is with surgery to remove your appendix. In fact, appendicitis is the number one cause of emergency abdominal surgery in the U.S. You may be treated for an infection first, before your surgery. It's important to treat the appendicitis quickly because you can develop a collection of pus called an abscess in your abdomen once your appendix bursts. Don't worry about going through life without an appendix. People live healthy lives without it. Once you've had your appendix taken out, you should feel a lot better. If your appendix has ruptured, it may take you longer to recover. You may also develop an abscess or other complications. That's why you don't want to wait until your appendix has already burst to get treated. Call your doctor for any severe pain in your abdomen, especially if you also have a fever, vomiting, constipation, dizziness, or other severe symptoms.

    There are three body views (front, back, and side) that can help you to identify a specific body area. The labels show areas of the body which are identified either by anatomical or by common names. For example, the back of the knee is called the “popliteal fossa,” while the “flank” is an area on the side of the body.
