Positioning exercises in improving the quality of magnetic-controlled capsule endoscopy

Area of Science:

• Gastroenterology
• Medical Imaging
• Endoscopy

Background:

• Optimal gastric preparation is crucial for Magnetic-controlled Capsule Endoscopy (MCE) quality.
• Current preparation methods lack a standardized consensus.
• This study investigates the value of positioning exercises in MCE preparation.

Purpose of the Study:

• To evaluate the clinical efficacy of positioning exercises in enhancing MCE examination quality.
• To compare the effectiveness of positioning exercises combined with medication versus medication alone for MCE preparation.

Main Methods:

• A retrospective analysis of 326 patients undergoing MCE from January 2020 to December 2023.
• Patients were divided into a conventional medication preparation (CMP) group and a positioning exercises (PE) group.
• Outcomes assessed included gastric cavity cleanliness, visibility scores, and positive lesion detection rates.

Main Results:

• The PE group demonstrated significantly higher cleanliness (19.52±2.26 vs 15.89±2.82) and visibility scores (15.09±2.31 vs 10.93±2.12) across all regions (P<0.001).
• MCE examination time was reduced in the PE group (21.29±5.82 min) compared to the CMP group (30.54±6.37 min) (P<0.001).
• No significant difference in positive lesion detection rates was observed between the groups (P>0.05).

Conclusions:

• Positioning exercises before MCE significantly improve gastric mucosal image quality.
• This preparation technique also leads to a shorter examination duration for patients.
• Positioning exercises represent a valuable addition to conventional MCE preparation protocols.
