Study Notes
Appendicitis
- Obstruction of the appendix lumen is common in acute appendicitis.
- Obstruction leads to fluid buildup, pressure increase, and impaired blood supply within the appendix.
- The appendix experiences inflammation, edema, ulceration, and infection due to the pressure buildup.
- Purulent exudate formation further distends the appendix.
- Tissue necrosis and gangrene can occur within 24 to 36 hours if untreated.
- Perforation (rupture) can occur, releasing GI contents into the abdominal cavity.
- Peritonitis develops from the released GI contents, causing inflammation and bacterial infection in the abdomen.
Types of Appendicitis
- Simple appendicitis: inflamed appendix but intact
- Gangrenous appendicitis: tissue necrosis and microscopic perforations present
- Perforated appendicitis: gross perforation and contamination of the peritoneal cavity
Appendicitis
- Obstruction of the appendix's proximal lumen is a common factor in acute appendicitis.
- Following obstruction, the appendix swells due to fluid secretions from its inner lining.
- Increased pressure within the appendix restricts blood flow, leading to inflammation, swelling, ulcers, and infection.
- Pus formation further expands the appendix.
- Without treatment, tissue death and gangrene develop within 24 to 36 hours, potentially leading to perforation.
- Appendix rupture releases intestinal contents into the abdominal cavity, causing peritonitis, a severe inflammation and bacterial infection throughout the abdomen.
- Appendicitis is classified based on its stage:
- Simple appendicitis: inflammation without tissue damage
- Gangrenous appendicitis: tissue death with tiny perforations
- Perforated appendicitis: visible rupture and contamination of the abdominal cavity
Etiology of Appendicitis
- Appendicitis is usually caused by an obstruction in the appendix lumen.
- Obstruction type varies with age.
- In children, it is usually caused by twisting of the appendix or mucus/feces obstruction.
- In young adults, it is usually caused by hyperplasia of lymphoid tissue.
- In older adults, it is usually caused by fibrosis, fecaliths, or tumors.
- Appendicitis can occur at any age due to parasitic infections in areas where they are endemic.
- Obstruction causes increased pressure in the appendix lumen, leading to ischemia, inflammation, cellular death, and ulceration.
Risk Factors and Prevention
- Adolescent boys are at the highest risk of developing appendicitis, followed by adolescent girls.
- Appendicitis can occur at any age.
- There is no known prevention for appendicitis.
- High fiber diets containing fresh fruits and vegetables may reduce the risk of appendicitis, but further research is needed to understand the mechanism.
Appendicitis Risk Factors
- Adolescent boys are at the highest risk of developing appendicitis, followed by adolescent girls.
- Appendicitis can occur at any age.
Appendicitis Prevention
- There is no known way to prevent appendicitis.
- A high-fiber diet, including fresh fruits and vegetables, may potentially reduce the risk of developing appendicitis.
- Further research is needed to determine the connection between dietary fiber and appendicitis, and the mechanism by which fiber may reduce risk remains unclear.
Appendicitis Obstruction Causes
- Appendicitis is most often initiated by a blockage within the appendiceal lumen.
- The cause of the obstruction varies depending on age.
- In children, appendicitis obstruction is commonly caused by appendix twisting, mucus, or feces.
- In young adults, lymphoid tissue enlargement is a frequent culprit.
- Older adults are more likely to experience appendicitis due to fibrosis, fecalith, or a tumor.
- In regions where parasites are prevalent, parasitic infections can trigger appendicitis at any age.
- Persistent mucus secretion following acute obstruction within the appendiceal lumen increases pressure.
- This increased pressure can lead to ischemia, inflammation, cellular death, and ulceration.
