Intestinal Ultrasonography As an Alternative to Fecal Calprotectin to Monitor Patients with Crohn’s Disease: Experience from a Novice Sonographer
Digestive Diseases and Sciences(2024)
Abstract
While fecal calprotectin (Fcal) is now recommended, the positioning of intestinal ultrasonography (IUS) is still unknown to monitor patients with CD. To assess the agreement between IUS performed by a novice sonographer and Fcal to detect active CD and to compare these two monitoring tools to determine the need for therapeutic escalation. In this cross-sectional prospective study, we consecutively included CD patients ≥ 18 years-old with concomitant IUS and Fcal testing within 7 days. IUS was performed by a novice sonographer. The endpoints were the agreement between IUS and Fcal (> 150 µg/g) to detect active CD and the need for therapeutic escalation. Among 66 patients undergoing IUS, 56 patients had also Fcal testing. The agreement between IUS and Fcal to detect an active CD was 80.4
