The utility of faecal calprotectin to predict post-operative recurrence in Crohńs disease

ABSTRACTObjective Endoscopic recurrence in Crohns disease occurs in up to 80% of patients during the first year after surgery. Due to this, these patients need close monitoring. Faecal calprotectin has been proposed to be used as a non-invasive marker to monitor inflammatory activity. Up to now the use of faecal markers in endoscopic recurrence has been scarcely studied and with contradictory results. Material and methods This was a cross-sectional observational study of diagnostic validity. It included all patients with Crohns disease (CD) and ileocolic resection retrospectively who had had an ileocolonoscopy and a determination of faecal calprotectin before this colonoscopy, from 2007 to 2015. Results Ninety-seven patients were included. We observed that the mean value of faecal calprotectin increased as the Rutgeerts score increased. The variable of that most statistical significance obtained in bivariate analysis was faecal calprotectin (p < 0.0001). Area under curve (AUC) of faecal calprotectin in en...
