Optimizing bowel cleanliness for video capsule endoscopy (VCE) is challenging due to limited high-quality studies. While preparations and prokinetics likely improve small bowel cleanliness, optimal methods remain undetermined.

Area of Science:

  • Gastroenterology
  • Medical Devices

Background:

  • Evaluating bowel preparations, prokinetics, and postural tricks for video capsule endoscopy (VCE) is hindered by numerous factors.
  • Most existing studies are published in abstract form, possess low methodological quality, and lack randomized comparisons.
  • The absence of a validated scale for assessing bowel cleanliness complicates inter-study comparisons and generalizable conclusions.

Purpose of the Study:

  • To address the challenges in evaluating the efficacy of interventions for improving bowel cleanliness in VCE.
  • To synthesize current understanding and identify knowledge gaps regarding bowel preparation, prokinetics, and postural techniques in VCE.

Main Methods:

  • Review of existing literature and consensus from the Fifth International Conference on Capsule Endoscopy.

  • Analysis of factors affecting bowel cleanliness, completeness of examination, and diagnostic yield in VCE.

    • Main Results:

    • A limited consensus suggests that preparations and prokinetics likely enhance small bowel cleanliness.
    • It is probable that these interventions improve gastric transit time (GTT), small bowel transit time (SBTT), and examination completeness.
    • Postural modifications, such as remaining recumbent in the right lateral position, may shorten GTT.

    Conclusions:

    • Optimal bowel preparation type, dosage, and timing require further determination.
    • Insufficient data exists on prokinetics and postural tricks to draw firm conclusions.
    • Unanswered questions persist regarding the impact of these interventions on diagnostic yield, miss rates, adverse effects, and patient acceptance.
