Abstract

Background

Capsule endoscopy is currently available as a noninvasive and effective diagnostic modality to identify small bowel abnormalities, with a completion rate to the cecum between 75.1 and 95.6%. A novel magnetically controlled capsule endoscopy (MCE) system could facilitate passage of the capsule through the pylorus, thereby reducing the gastric transit time (GTT).

Objective

We performed this study to determine whether magnetic steering could improve the capsule endoscopy completion rate (CECR) compared to standard protocol.

Methods

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

Results

CECR was significantly higher in the intervention group (n = 107) than control group (n = 120) (100% vs. 94.2%, P = 0.02), with a significantly shorter GTT (22.2 vs. 84.5 min, P < 0.001) and PTT (4.4 vs. 56.7 min, P < 0.001). Rapid gastric transit rate in the intervention group was significantly higher than the control group (58.9% vs. 15.0%, P < 0.001). There were no statistical differences in the diagnostic yields between the two groups.

Conclusions

Magnetic steering of capsule endoscopy improves small bowel CECR by reducing GTT, adding further support to MCE as a practical tool for noninvasive examination of both the stomach and small bowel.
