Purpose/Background: Fecal calprotectin (FC) is increasingly used for the diagnosis and follow-up of luminal Crohn's disease (CD). While the diagnosis of CD is often difficult in cases of 1st episode of anal abscess, FC could differentiate CD-related to perianal fistulae from cryptoglandular ones. The aim of this study was to evaluate the diagnostic performance in emergency of FC for the diagnosis of CD in 1st episode of anal abscesses.

Methods/Interventions: From January 2021 to December 2023, all consecutive patients managed for anal abscess were included in this prospective monocentric observational study. FC was collected on the day of drainage in the operating room. The rate of FC was compared between patients with and without CD, and the performance characteristics of FC to discriminate patients with CD were evaluated.

Results/Outcomes: During the study period, 98 patients underwent drainage of anal abscesses, 34 of whom had CD. Epidemiological data were not significantly different between groups. The median FC value was 176 ug/g among patients with CD and 32.5 ug/g among patients without CD (p=0.039). The area under the ROC curve was 0.731, and the most discriminating value for the diagnosis of CD was 100 ug/g, with a sensitivity of 75% and a specificity of 70%. The rate of patients with a CF value>100ug/g was significantly higher among those with Crohn's disease (75% vs. 33%, p=0.03).

Conclusion/Discussion: In an emergency, a FC value>100ug/g in a patient presenting with an anal abscess should raise the diagnosis of CD
