Classification
Based on Type of Obstruction
Classifications based on the type of obstruction include:[1]
- 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 and is associated with the following types of bacterial infiltration:[2]
- Escherichia coli
- Peptostreptococcus
- Bacteroides fragilis
- Pseudomonas species
- Non-perforating
