Perianal Abscess or Fistula Tied to Risk for Crohn's Disease in Older Children
Perianal abscesses or fistulas in children can be an early sign of Crohn's disease. Recognizing which kids are at higher risk helps guide follow-up and testing so diagnosis isn't delayed.

What To Know
Children who present with perianal abscess or fistula-in-ano appear to have a substantial risk of later being diagnosed with Crohn's disease, especially older children and those with recurrent perianal disease or GI symptoms.
In this retrospective multicenter study of 152 children (median age 11.1 years) followed for a median 6.2 years, 21.1% were eventually diagnosed with Crohn's disease; the median interval from perianal presentation to diagnosis was 4.7 months. Higher faecal calprotectin levels were reported in the subset who developed Crohn's disease.
What to watch for: older children (particularly age 12–18) and those with recurrent perianal problems or accompanying GI symptoms had higher odds of a Crohn's diagnosis. The authors recommend heightened clinical awareness and follow-up after an initial perianal abscess or fistula presentation.
Practical notes: this was a retrospective study from five Dutch hospitals with limitations including sample size and potential underrepresentation of non-surgical cases.
The findings suggest that measuring faecal calprotectin and monitoring for GI symptoms could help identify children who need further evaluation for IBD, but the study does not define specific testing or management protocols.
This is a retrospective multicenter cohort study with modest sample size and possible selection bias toward surgically managed children. Results point to associations (age, recurrence, GI symptoms, higher faecal calprotectin) but do not establish causation or specific clinical protocols.
