Summary
Crohn disease (CD) frequently causes anorectal conditions like abscesses and fistulas, affecting 28% of patients. In some cases, anal lesions appeared years before intestinal symptoms, particularly in those with large bowel involvement.
Area of Science:
- Gastroenterology
- Colorectal Surgery
Background:
- Crohn disease (CD) is a chronic inflammatory bowel disease.
- Anorectal complications are common in CD patients.
Purpose of the Study:
- To investigate the incidence and characteristics of anorectal lesions in Crohn disease patients.
- To explore the relationship between anal lesions and intestinal symptoms in CD.
Main Methods:
- Retrospective analysis of 503 Crohn disease patients.
- Review of medical records for anorectal abscess, fissure, or fistula development.
- Comparison of lesion occurrence based on disease location (small vs. large bowel).
Main Results:
- 28% of CD patients developed anorectal lesions.
- 9.3% of patients had anal lesions precede intestinal symptoms by up to 12 years.
- Large bowel involvement was associated with a higher likelihood of developing anal lesions and presenting with them.
Conclusions:
- Anorectal lesions are a significant complication in Crohn disease.
- The timing of anal lesion onset relative to intestinal symptoms varies.
- Large bowel disease increases the risk of anorectal complications in CD.
