The following are the most important diseases or complications that can be caused by appendicitis (appendicitis):
Mouth, esophagus (food pipe), stomach, and intestines (K00-K67; K90-93).
- Abdominal abscesses
- Appendiceal perforation* (“appendix rupture“).
- Peritonitis (inflammation of the peritoneum)
- Perityphlitic abscess – formation of an encapsulated collection of pus around the appendix.
- Recurrent appendicitis after appendectomy (appendectomy) (due to stump appendicitis).
Caution.
A high rate of perforation is expected in infancy, due to diagnostic difficulties and rapid progression:
- 50% in the second and until the third year of life!
- 20-30% until the fifth year of life
- 10% from the fifth year of life
Prognostic factors
- Children with IgE-mediated allergies were three times less likely than other children to suffer complications from acute appendicitis (19.6% versus 46.9%; adjusted odds ratio of 0.33, which was highly significant with a 95% confidence interval of 0.18 to 0.59)
