New reduced volume preparation regimen in colon capsule endoscopy

Area of Science:

• Gastroenterology
• Endoscopy
• Medical Devices

Background:

• Colon capsule endoscopy (CCE) requires effective bowel preparation for diagnostic accuracy.
• Conventional bowel preparation methods can be burdensome for patients.

Purpose of the Study:

• To evaluate the efficacy of a novel reduced volume bowel preparation regimen for CCE.
• To compare this method against the standard high-volume preparation.

Main Methods:

• A pilot, multicenter, randomized controlled trial compared a reduced volume method (no PEG-ELS day before) with a conventional volume method (2L PEG-ELS day before).
• Both groups received PEG-ELS on the procedure day, followed by magnesium citrate boosters.
• Capsule videos were assessed for bowel cleansing quality.

Main Results:

• Adequate bowel preparation was achieved in 94% of the reduced volume group versus 86% in the conventional group.
• Capsule excretion within battery life occurred in 71% of the reduced volume group compared to 55% in the conventional group.
• All non-excreted capsules reached the left colon, and only one mild adverse event was reported.

Conclusions:

• The proposed reduced volume bowel preparation method is a viable and effective alternative to conventional methods for CCE.
• This method simplifies preparation by omitting polyethylene glycol electrolyte lavage solution (PEG-ELS) the day prior.
• The findings support the use of this reduced volume regimen for improved patient compliance and procedural success.
