Abstract:
Background: Video capsule endoscopy (VCE) is a safe and effective way of
investigating obscure gastrointestinal bleeding. One of the main limitations of VCE is
suboptimal visualisation due to prolonged gastric transit time (GTT) or rapid small intestinal
transit time (SITT). The role of metabolic risk factors, diabetes, and medications on transit
times remains unclear.
Aim: The aim of this study was to assess the impact of diabetes, obesity, medications, and
metabolic syndrome on transit times at VCE.
Methods: The study performed was a single centre, observational study.
Results: Significant predictors of decreased GTT were increasing age and use of beta blocker
medication. No predictive factors for increased GTT were identified. Significant predictors of
decreased SITT on univariate analysis were increased GTT, serum glucose >5mmol/L, obesity,
and diabetes. On multivariate analysis, increased GTT and glucose remained significant.
Conclusion: Beta-blocker therapy reduces GTT. Hyperglycaemia at the time of VCE reduces
SITT. These allow for possible therapeutic strategies to improve the diagnostic yield at VCE.
