The role of surgery for children with perianal Crohn's disease.

PURPOSE: Children with perianal Crohn's disease (PCD) are a unique and diverse patient population. The purpose of this study was to describe the spectrum of disease and role of surgery.

METHODS

A retrospective chart review of all children having at least one surgical intervention for PCD over 10 years was performed.

RESULTS

Fifty-seven patients (63% male) aged 0.5-17 (median 13) years were identified. Perianal disease consisted of skin tags (49%), superficial fistulae (49%), deep fistulae (37%), superficial abscesses (68%), deep abscesses (9%), skin breakdown (19%), and anal strictures (7%). 84% received anti-TNF therapy, with 27% treated with a second anti-TNF medication. Minor surgical procedures, commonly done during anti-TNF therapy, included abscess drainage (67%) and seton placement (33%). Major surgical procedures, done almost exclusively after anti-TNF failure, included defunctioning ileostomy (23%) and subtotal colectomy (9%). Follow-up ranged from 7 to 160 (median 54) months.

CONCLUSIONS

Pediatric PCD has a wide range of disease severity. Minor surgery provides adequate drainage before and during anti-TNF therapy, while major surgery plays a role in medically refractory disease. Appropriate surgical intervention remains an important part of the treatment paradigm.
