What is appendicitis?
Appendicitis is inflammation of the
appendix, a small portion of the large intestine that hangs down from the
lower
right side. Although the appendix does not seem to serve any purpose, it
can still become diseased. If untreated, an
inflamed appendix can burst, causing infection and even death. About 1 in
500 people has appendicitis each year.
Appendicitis may occur after a viral infection in the digestive tract or
when the tube connecting the large intestine
and appendix is blocked by trapped stool. The inflammation can cause
infection, a blood clot, or rupture of the
appendix. Because of the risk of rupture, appendicitis is considered an
emergency. Anyone with symptoms needs to
see a doctor immediately. Symptoms include
Pain in the right side of the abdomen. The pain usually begins near the
navel and moves down and to the right.
The pain becomes worse when moving, taking deep breaths, coughing,
sneezing, and being touched in the
area.
Not everyone has all symptoms. It is
important that people with symptoms of appendicitis not take laxatives or
enemas to relieve constipation because these medicines could cause the
appendix to burst. People also should not
take pain medicine because it can mask symptoms that the doctor needs to
know about.
The doctor bases an appendicitis diagnosis on symptoms, a physical exam,
blood tests to check for signs of infection
such as a high white blood cell count, and urine tests to rule out a
urinary tract infection. Some doctors use
ultrasound to see whether the appendix looks inflamed. Treatment is
surgery to remove the appendix, called
appendectomy. Doctors are beginning to use laparoscopic surgery for
appendectomy. This technique involves
making several tiny cuts in the abdomen and inserting a miniature camera
and surgical instruments. The surgeon
then removes the appendix with the instruments, so there is no need to
make a large incision in the abdomen. People
can live a normal life without their appendix--no changes in diet,
exercise, or other lifestyle factors are necessary. |
