Acute disease of the GI tract may be caused by the pathogen itself or by a bacterial or other toxin. Acute inflammatory disorders such as appendicitis and peritonitis result from contamination of damaged or normally sterile tissue by a client’s own endogenous or resident bacteria (Lemone and Burke, 2008, page 766). Appendicitis is the inflammation of the vermiform (wormlike) appendix; the appendix is a small fingerlike appendage about 10 cm (4 in) long, attached to the cecum just below the ileocecal valve, which is the beginning of the large intestine. It is usually located in the right iliac region, at an area designated as McBurney’s point. McBurney’s point, located midway between the umbilicus and the anterior iliac crest in the right lower quadrant. It is the usual site for localized pain and rebound tenderness due to appendicitis during later stages of appendicitis. The function of the appendix is not fully understood, although it regularly fills and empties digested food. Some scientists have recently proposed that the appendix may harbor and protect bacteria that are beneficial in the function of the human colon. Appendicitis is the most common cause of acute inflammation in the right lower quadrant of the abdominal cavity. The lower quadrant pain is usually accompanied by a low-grade fever, nausea, and often vomiting. Loss of appetite is common. In up to 50% of presenting cases, local tenderness is elicited at Mc Burney’s point applied located at halfway between the umbilicus and the anterior spine of the Ilium. Rebound tenderness (ex. Production or intensification of pain when pressure is released) may be present. The extent of tenderness and muscle spasm and the existence of the constipation or diarrhea depend not so much on the severity of the appendiceal infection as on the location of the appendix. If the appendix curls around behind the cecum, pain and tenderness may be felt in the lumbar region. Rovsing’s sign may be elicited by palpating the left lower quadrant. If the appendix has ruptured, the pain become more diffuse, abdominal distention develops as a result of paralytic ileus, and the patient’s condition worsens.

The disease is more prevalent in countries in which people consume a diet low in fiber and high in refined carbohydrates. It is the most common reason for emergency abdominal surgery, affecting 10% of the population. Although appendicitis affects a person at any age, the peak incidence is between the ages of 20 and 30 years old in which the vast majority of clients are most common in adolescents and young and slightly more common in males than females. About 7% of the population will have appendicitis at some time in their lives (Lemone and Burke, 2008 page 766). The major complication of appendicitis is perforation of the appendix, which can lead to peritonitis, abscess formation (collection of purulent material), or portal Pyle phlebitis, which is septic thrombosis of the portal vein caused by vegetative emboli that arise from septic intestines. Perforation generally occurs 24 hours after the onset of pain symptoms include a fever of 37.7 degree Celsius or 100 degree Fahrenheit or greater, a toxic appearance and continued abdominal pain or tenderness.

Appendicitis can be classified as simple, gangrenous, or perforated, depending on the stage of the process. In simple appendicitis, the appendix is inflamed but intact. When areas of tissue necrosis and microscopic perforations are present in the appendix, the disorder is called gangrenous appendicitis. A perforated appendix shows evidence of gross perforation and contamination of the peritoneal cavity (LeMone & Burke, 2008 page 766). Peritonitis can be primary or secondary.

Primary peritonitis is an acute bacterial infection that is not associated with perforated viscus, or organ. Bacterial infection is the usual cause and may be associated with an infection by the same organism...
