Study Notes
Appendicitis Causes
- Appendicitis is almost always caused by an obstruction of the appendiceal lumen.
- The type of obstruction varies with age.
- In children, appendiceal twisting, mucus, and feces can cause obstruction.
- In young adults, lymphoid tissue hyperplasia is a common cause.
- In older adults, fibrosis, fecaliths, and tumors can cause obstruction.
- Parasitic infections can also cause appendicitis, regardless of age, in endemic areas.
- Continued mucus secretion after obstruction increases pressure inside the appendix.
- This increased pressure leads to ischemia, inflammation, cell death, and ulceration.
Appendicitis
- Initial pain is mild and generalized, often in the upper abdomen.
- Pain intensifies within 4 hours and localizes to the right lower quadrant of the abdomen (RLQ).
- Movement, walking, and coughing aggravate pain.
- Localized and rebound tenderness found at McBurney's point (between the umbilicus and the anterior superior iliac spine).
- Rebound tenderness is characterized by pain relief with direct palpation of McBurney's point, followed by pain upon release of pressure.
- Extension or internal rotation of the right hip increases pain.
- Low-grade fever, anorexia, nausea, and vomiting are common symptoms.
- Diagnosis may be delayed in older adults due to less acute pain and localized tenderness.
- Appendicitis is more virulent in older adults, leading to quicker complications and increased mortality.
- Pregnant women may experience RLQ, periumbilical, or right subcostal pain due to the distended uterus.
- In adolescents and young adult women, symptoms must be differentiated from ovulation pain (mittelschmerz), ruptured ectopic pregnancy, and pelvic inflammatory disease.
- Complications include perforation, peritonitis, and abscess formation.
- Perforation is characterized by increased pain, high fever, and can lead to localized/generalized peritonitis.
- Chronic appendicitis involves chronic abdominal pain and recurring acute attacks over several months.
- Other conditions, such as inflammatory bowel disease (IBD) and renal disorders, can mimic chronic appendicitis.
Acute Appendicitis
- Pain can begin at the umbilicus and shift towards the right side, depending on the appendix's position.
Clinical Therapies for Acute Appendicitis
- Analgesics for pain management.
- Antibiotics and/or surgery are anticipated.
- Removal of the ruptured appendix.
- Pain management.
- Antibiotics.
- Fluid resuscitation.
- Supportive treatment to maintain vital signs.
Peritonitis
- High fever, acute severe abdominal pain, and abdominal distention.
- Can be fatal if not treated aggressively and rapidly.
Chronic Appendicitis
- Chronic recurrent abdominal pain over several months.
Clinical Therapies for Chronic Appendicitis
- Appendectomy.
- Pain management.
- Antibiotics.
Acute Appendicitis
- Initial pain: Starts as mild, generalized, or upper abdominal pain, but intensifies and localizes to the right lower quadrant (RLQ) within four hours.
- Aggravating factors: Moving, walking, coughing, and palpation.
-
McBurney point: Localized and rebound tenderness are noted at McBurney point (between the umbilicus and anterior superior iliac spine).
- Rebound tenderness: Pain relief with direct palpation, followed by pain on release of pressure.
- Other symptoms: Low-grade fever, anorexia, nausea, and vomiting.
-
Diagnosis in older adults: Diagnosis may be delayed due to less acute pain and local tenderness.
- Increased risk: Older adults experience a more virulent course, leading to earlier complications and increased mortality.
- Pregnancy: RLQ, periumbilical, or right subcostal (under the rib cage) pain may occur due to appendix displacement by the distended uterus.
- Differential Diagnosis: In adolescents and young adult women, differentiate symptoms from ovulation (mittelschmerz), ruptured ectopic pregnancy, and pelvic inflammatory disease.
-
Complications: Perforation, peritonitis, and abscess (accumulation of pus).
-
Perforation: Manifested by increased pain and high fever.
- Consequences: Can lead to a localized abscess, local peritonitis, or generalized peritonitis.
-
Perforation: Manifested by increased pain and high fever.
Chronic Appendicitis
- Symptoms: Chronic abdominal pain and recurrent acute attacks at intervals of several months or more.
- Differential Diagnosis: Often mimics manifestations of inflammatory bowel disease (IBD) and renal disorders.
Acute Appendicitis Treatment
- Analgesics: For pain management.
- Antibiotics: For infection control.
- Surgery: Appendectomy (removal of the appendix).
Peritonitis
- Symptoms: High fever, severe abdominal pain, abdominal distention.
-
Treatment: Prompt and aggressive treatment is crucial to prevent death.
- Management: Removal of the ruptured appendix, pain management, antibiotics, fluid resuscitation, and supportive care to maintain vital signs.
Chronic Appendicitis Treatment
- Appendectomy: Removal of the appendix.
- Pain Management: Analgesics.
- Antibiotics: For infection control.
