Faecal calprotectin (FC) is a noninvasive marker that reflects intestinal inflammation with good sensitivity. A prior study indicated that FC values above 150 μg/g could distinguish between anal fistulas (AF) of cryptoglandular or Crohn's disease (CD) origin. It is hypothesized as a useful triage test to rule out CD in newly referred AF patients, thus reducing the number of ileocolonoscopies performed and optimizing treatment regimens in AF while minimizing patient discomfort as well as healthcare costs. The aim of the study was to determine the accuracy of FC in distinguishing between anal fistulas of cryptoglandular and CD origin, as well as compare characteristics in fistulas.
