CHAPTER I
INTRODUCTION
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.
Acute appendicitis can occur when a piece of food, stool or object becomes trapped
in the appendix, causing irritation,
inflammation, and the rapid growth of bacteria and infection. Acute appendicitis can also happen after a gastrointestinal infection. Rarely, a tumor may cause acute appendicitis. Sometimes the cause of acute appendicitis is not known. The inflammation is usually caused by a blockage, but may be caused by an infection. Without treatment, an inflamed appendix can rupture, causing infection of the peritoneal cavity (the lining around the abdominal organs) and even death.
Appendicitis is one of the most common causes of emergency abdominal surgery. Up to 75,000 appendectomies are done each year
1
in the U.S. The estimated population in the Philippines is 86, 241,
6972 and the incident rate of acute appendicitis is 215,604 as of year
2011. Appendicitis is one of the more common surgical emergencies, and it is one of the most common causes of abdominal pain. In the
United States, 250,000 cases of appendicitis are reported annually, representing 1 million patient-days of admission. The incidence of acute appendicitis has been declining steadily since the late 1940s, and the current annual incidence is 10 cases per 100,000 populations. Appendicitis occurs in 7% of the US population, with an incidence of 1.1 cases per 1000 people per year. Some familial predisposition exists.
