Magnetic Steering Improves Small Bowel Capsule Endoscopy Completion Rate

Not Applicable

Completed

• Conditions: Small Bowel Disease; Capsule Endoscopy

• Registration Number: NCT03482661
• Lead Sponsor: Zhuan Liao

Brief Summary

Patients referred for magnetically controlled capsule endoscopy (MCE) in the participating center from June 2017 to November 2017 were prospectively enrolled. Magnetic steering of MCE was performed after standard gastric examination. Capsule endoscopy completion rate (CECR), gastric transit time (GTT), pyloric transit time (PTT) and rapid gastric transit rate (GTT ≤ 30 min) were compared with the historical control group enrolled from January 2017 to May 2017.

Detailed Description

Background and aims: Capsule endoscopy is currently available as a noninvasive and effective diagnostic modality to identify small bowel abnormalities, while the completion rate ranged from 75.1% to 95.6%. A novel magnetically controlled capsule endoscopy (MCE) system could facilitate the capsule to pass through pylorus thereby reducing the gastric transit time (GTT). The investigators perform this study to determine the potential improvement in capsule endoscopy completion rate (CECR) under magnetic steering vs standard mode.

Methods: Patients referred for magnetically controlled capsule endoscopy (MCE) in the participating center from June 2017 to November 2017 were prospectively enrolled. Magnetic steering of MCE was performed after standard gastric examination. Capsule endoscopy completion rate (CECR), gastric transit time (GTT), pyloric transit time (PTT) and rapid gastric transit rate (GTT ≤ 30 min) were compared with the historical control group enrolled from January 2017 to May 2017.
