Fecal calprotectin one year after ileocaecal resection for Crohn's disease - A comparison with findings at ileocolonoscopy

We found no statistical difference in the concentrations of calprotectin between patients in endoscopic remission and patients with a recurrent disease one year after ileocaecal resection for Crohn's disease. However, among the minority of patients with low or high values, FC indicated remission and recurrence, respectively. There was significant variation of the fecal calprotectin concentrations over time, which affects the utility of calprotectin in clinical practice.
