Stomal calprotectin as a biomarker for assessing Crohn disease activity in patients with stomas.

Background: Faecal calprotectin is a reliable biomarker for lower gastrointestinal inflammation. However, there are limited data on the utility of calprotectin from stoma effluent.

Aim: The aim of this study was to determine the performance of stomal calprotectin in identifying Crohn disease activity in those with a stoma.
