The role of calprotectin in predicting endoscopic post-surgical recurrence in asymptomatic Crohn's disease: a comparison with ultrasound.

Abstract

When performed three months after surgery ultrasound is more specific than calprotectin in predicting endoscopic recurrence. Faecal calprotectin at a dosage > 200 mg/L seems to have a better sensitivity than ultrasound. Values of calprotectin > 200 mg can be an indication to colonoscopy in the group of patients with negative ultrasound in order to detect early recurrence.
