Study Notes

Anatomy of the Appendix

McBurney’s point is the classic location for tenderness in acute appendicitis; a significant indicator when the patient can point to this exact location.
Point tenderness is tested by having the patient cough or perform a Valsalva maneuver to identify pain location.

Appendicitis Indicators

Pain typically starts as vague periumbilical pain due to visceral nerve innervation, shifting to localized right lower quadrant (RLQ) pain, indicating parietal pain.
Pathognomonic signs of acute appendicitis include nausea, vomiting, anorexia, and fever that worsens as pain localizes to RLQ.

Key Signs

Rovsing’s Sign: Pain in the RLQ when pressure is applied to the left lower quadrant (LLQ).
Psoas Sign: Positive when the posterior appendix is retrocecal; elicited by flexing the hip.
Obturator Sign: Positive when the appendix is pelvic; assessed through hip movements.
Primary physical finding for uncomplicated appendicitis is direct rebound tenderness in RLQ.

Appendicitis Variants

Diagnosis and management plans differ for appendicitis in special populations such as pregnant women and the elderly.
Differential diagnoses for RLQ pain include perforated viscus, peptic ulcer, and diverticulitis.

Meckel's Diverticulum

Understanding of Meckel's diverticulum anatomy is crucial; diseases associated with this condition will also be discussed.

General Management

An appropriate management plan is essential for diseases involving the appendix and Meckel's diverticulum, stressing the necessity of collaboration across subspecialties for comprehensive patient care.

Notes on Antibiotic Use

Specific antibiotics like quinolones should be avoided in pediatric patients (e.g., around 15 years) due to risks of growth plate closure.
In older populations, quinolones may also pose risks and should be considered carefully.

Microflora Associations

Foregut microflora predominantly consists of Gram-positive organisms and anaerobes.
Midgut microflora includes Gram-negative organisms, specifically E. coli and Bacteroides fragilis, which can be treated with metronidazole, and a potential C. difficile infection with vancomycin or clindamycin.
