What is the appendix?
The appendix is a closed-ended, narrow tube that attaches to the cecum (the first part of the colon) like a worm. (The anatomical name for the appendix, vermiform appendix, means worm-like appendage.) The inner lining of the appendix produces a small amount of mucus that flows through the appendix and into the cecum. The wall of the appendix contains lymphatic tissue that is part of the immune system for making antibodies. Like the rest of the colon, the wall of the appendix also contains a layer of muscle.
The appendix is a small, finger-shaped sac extending from the first part of the large intestine. It is removed when it becomes inflamed or infected. An infected appendix can leak and infect the entire abdominal area, which can be deadly. See: Peritonitis
An appendectomy is done under general anesthesia, which means you are asleep and do not feel any pain during the surgery. The surgeon makes a small cut in the lower right side of your belly area and removes the appendix.
The appendix can also be removed using minimally invasive techniques. This is called a laparoscopic appendectomy. It is performed with small incisions and a camera.
If the appendix ruptured or a pocket of infection (abscess) formed, your abdomen will be thoroughly washed out during surgery. A small tube may be left in the belly area to help drain out fluids or pus.
There’s no way to prevent appendicitis. Because the appendix is so close to the large intestine, it can become clogged with stool and bacteria. Other times mucus produced by the appendix can thicken and cause a blockage. In both cases, once the opening to the appendix is congested, it can become inflamed and swollen, causing appendicitis.
Appendicitis can cause sudden pain in the middle of the abdomen, usually concentrated around the bellybutton. The pain often moves to the lower right part of the abdomen. At first, pain might come and go, then become persistent and sharp.
Appendicitis also can cause : –
If the appendix bursts, a child can develop a high fever, and pain will move throughout the abdominal area.
With an unruptured appendix, the patient’s recovery time is relatively quick. The morning after surgery, clear liquids are offered. Once those are tolerated, the diet progresses to solid food. Once the patient is eating and drinking, the intravenous is removed. Physical activity, such as getting out of bed, begins on the same day as surgery or the next morning. Most patients need medication to relieve the pain in and around the incision. The smaller incisions of a laparscopic procedure often cause less pain than the large incision made in open appendectomy.
The nursing staff continues to monitor the patient for signs of infection and checks that the incision is healing. Patients with uncomplicated surgeries usually leave the hospital 1 or 2 days following surgery.
Patients tend to recover quickly after a simple appendectomy. Most patients leave the hospital in 1 – 3 days after the operation. Normal activities can be resumed within 1 – 3 weeks after leaving the hospital.
Recovery is slower and more complicated if the appendix has ruptured or an abscess has formed.
Living without an appendix causes no known health problems.
