What happens during a Appendectomy?

The appendix is a small, finger-shaped organ that branches off from the first part of the large intestine. 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.

Digestive system

Appendectomy is done using either:

  • Spinal anesthesia -- Medicine is put into your 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.

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

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

If the 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 would someone need a Appendectomy?

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 count (WBC), may be done to check for infection.
  • The provider may order a CT scan or ultrasound to make sure 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.

What are the 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
What to expect after a Appendectomy

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.

Use of Antibiotic Irrigation to Decrease Wound Infections in Pediatric Perforated Appendicitis

Summary: The proposed study will investigate whether antibiotic irrigation using a gentamicin/clindamycin solution during laparoscopic appendectomy is superior in preventing postoperative wound infections and IAA in perforated appendicitis compared to suction without irrigation. This will be the first prospective study to compare these two options in pediatric PA.
