Severe Consequences of Pediatric Perianal Crohn’s Disease

Posted on by

A Strom et al. Clin Gastroenterol Hepatol 2026; 24: 1960-1969. Perianal Disease in Pediatric-Onset Crohn’s Disease: Incidence, Disease Course, and Long-Term Outcomes

Methods: In this nationwide Danish registry, a pediatric-onset CD cohort from 1980 to 2022 was identified. Outcomes for patients with and without perianal disease were examined.

Key findings:

  • There were 2356 patients with pediatric-onset CD, of whom 769 (32.6%) developed perianal CD. The cumulative incidence of perianal CD was 14.0%, 21.1%, and 28.1% after 1, 5, and 10 years.  After 30 years, the incidence rate was 45.2%.
  • A stoma was required in 308 (40.1%) and 147 (9.3%) patients with and without perianal disease, respectively (aHR, 2.8).
Probability of Major Abdominal Surgery in Patients with and without Perianal Disease
  • When comparing patients with/without perianal disease, the aHR for major abdominal surgery, cancer, and mortality were 1.5, 0.8, and 1.5 , respectively.
Probability of Mortality in Patients with and without Perianal Disease
  • When comparing patients with/without perianal disease, the aHR for mortality was 1.5. Of mortalities, 35 had perianal disease (4.6%; mortality rate, 2.2/1000 person-years) and 33 did not (2.1%; mortality rate, 1.4/1000 person-years). However, the confidence interval was 0.9-2.7) indicating the precision of this finding is low.

Discussion: “In our study, patients without perianal disease were diagnosed with CD more frequently in recent decades than patients with perianal disease. The differences in distribution of CD diagnosis over calendar years may be due to shorter follow-up among patients diagnosed with CD in recent decades, improved treatment delaying disease progression, and increased detection of milder CD phenotypes over time.”

My take: This study reinforces and quantitates the view that having perianal Crohn’s disease portends an increased risk for severe complications. With improving treatments, perhaps the outcomes will be more favorable now and in decades hence.

“Temporary” Diversion for Distal Crohn’s Disease & Latest COVID Stats

AL Lightner et al. Inflamm Bowel Dis 2022; 28: https://doi.org/10.1093/ibd/izab126. Is Intestinal Diversion an Effective Treatment for Distal Crohn’s Disease?

In this retrospective study (n=132 adults), the indications for surgery were medically refractory proctocolitis with perianal disease (n = 59; 45%), perianal disease alone (n = 24; 18%), colitis (n = 37; 28%), proctitis (n = 4; 3%), proctocolitis alone (n = 4; 3%), and ileitis with perianal disease (n = 4; 3%)

Key findings :

  • The clinical and endoscopic response to diversion was 43.2% (n = 57) and 23.9% (n = 16).
  • At a median follow-up of 35.3 months, 25 patients (19%) had improved and had ileostomy reversal, but 86 (65%) did not improve, with 50 (38%) undergoing total proctocolectomy for persistent symptoms
  • Also, 24% experienced stoma morbidity (peristomal abscess, hernia or prolapse)

My take: In this study of adults with distal Crohn’s disease, a “temporary” stoma/fecal diversion was only temporary in ~20%. This information is quite important for patients when considering this treatment option.
