Overview
Appendicitis is a condition characterized by inflammation of the appendix. It can be classified into several subtypes based on perforation and the type of obstruction.
Classification
Based on Type of Obstruction
- Infectious processes
- Fibrosis - such as due to scar tissue from a previous surgery
- Fecaliths - hard fecal masses
- Neoplasia - carcinoid, adenocarcinoma, or mucocele
- Parasites - in endemic areas
- Calculi
- Lymphoid hyperplasia
Based on Perforation
- Perforating - increases in incidence with age[1] and is associated with the following types of bacterial infiltration:
- Escherichia coli
- Peptostreptococcus
- Bacteroides fragilis
- Pseudomonas species
- Non-perforating
