Video capsule endoscopy: is bowel preparation necessary?

Area of Science:

• Gastroenterology
• Medical Imaging

Background:

• Standardized bowel preparation protocols are lacking for video capsule endoscopy (VCE).
• Bowel preparation is often recommended to enhance visualization during VCE.

Purpose of the Study:

• To determine if bowel preparation significantly impacts small bowel mucosal visualization rates in VCE.
• To assess the relationship between fasting duration and small bowel visualization.

Main Methods:

• Retrospective analysis of 76 patients undergoing VCE from August 2014 to January 2016.
• Comparison of visualization rates between patients with and without bowel preparation (polyethylene glycol).
• Assessment of visualization based on fasting duration (short vs. long fast ≥12 hours).

Main Results:

• Small bowel mucosal visualization rates were similar with (92.5%) and without (88.9%) bowel preparation (p=0.44).
• Visualization rates were significantly higher in patients with a long fast (97.7%) compared to a short fast (81.3%) (p=0.019).

Conclusions:

• Bowel preparation does not significantly improve small bowel mucosal visualization during VCE.
• Prolonged fasting (≥12 hours) is significantly associated with improved visualization, suggesting it may be sufficient.
• Further randomized trials are needed to confirm these findings.
