Repetitive Position Change Improves Gastric Cleanliness for Magnetically Controlled Capsule Gastroscopy

Area of Science:

• Gastroenterology
• Medical Devices
• Diagnostic Imaging

Background:

• Effective gastric preparation is crucial for magnetically controlled capsule gastroscopy (MCCG).
• Dimethicone premedication is commonly used to improve visualization.
• Further optimization of gastric cleanliness is needed for enhanced MCCG procedures.

Purpose of the Study:

• To evaluate the efficacy of repetitive position changes post-dimethicone in improving gastric cleanliness for MCCG.
• To assess the impact of this technique on diagnostic yield and examination time.

Main Methods:

• Prospective randomized controlled trial involving patients undergoing MCCG.
• Patients received dimethicone, with one group performing repetitive position changes for 15 minutes.
• Gastric cleanliness, positive finding detection rates, examination time, and safety were primary and secondary outcomes.

Main Results:

• The position change group demonstrated significantly higher gastric cleanliness scores (21.2 vs. 18.6, P < 0.001).
• 100% of the position change group achieved acceptable cleanliness (score ≥ 18) versus 72.5% in the conventional group (P < 0.001).
• Gastric examination time was reduced in the position change group (13.2 min vs. 15.3 min, P = 0.043) with no difference in positive finding detection rates.

Conclusions:

• Repetitive position change after dimethicone significantly enhances gastric cleanliness for MCCG.
• This method improves procedural efficiency by reducing examination time.
• The technique is safe and does not compromise the detection of positive findings.
