Résumé
Standard capsule endoscopy (CE) is ineffective for upper gastrointestinal (GI) tract examination because it does not allow operator-controlled navigation of the capsule. Magnetically assisted capsule endoscopy (MACE) may offer a solution to these problems. This pilot study is aimed to evaluate the feasibility of MACE system in pediatric Crohn disease (CD) and if magnetic steering could enhance capsule gastric emptying when compared with standard CE. Pediatric CD patients already studied by standard small bowel CE were enrolled. All participants swallowed a magnetically assisted CE and an external magnetic field navigator was used to guide the capsule through the upper GI tract. Maneuverability, completeness of the MACE examination, differences in the esophageal transit time (ETT), gastric transit time (GTT), and pyloric transit time (PTT) between standard CE and MACE were assessed. Ten patients [mean age 11.4 years (range 6-15); 60% male] were enrolled. Maneuverability was defined as good and fair in 60% and 40% of participants, respectively. Completeness of MACE examination was 95%, 65%, and 92.5% in the esophagus, proximal, and distal stomach, respectively. Transpyloric passage of the capsule under magnetic control was successfully performed in 80% of patients. Magnetic intervention significantly increased ETT ( P < 0.001) and reduced GTT and PTT ( P = 0.002). No significant adverse events occurred. MACE is a safe and feasible technique in children. Magnetic steering enhances capsule gastric emptying and facilitates capsule transpyloric passage when compared with standard CE.
