abstract = {Background: The objective of this article is to study the role of Simethicone ± N-acetylcysteine in improving the mucosal visualization during oesophago-gastro-duodenoscopy (OGD).
Methods: The data retrieved from the published randomized controlled trials (RCTs) reporting the role of Simethicone ± N-acetylcysteine during OGD was analysed using the principles of meta-analysis. The summated outcome of continuous variables was expressed as standardized mean difference (SMD) and dichotomous data was presented in odds ratio (OR).
Results: Three RCTs on 654 patients reported OGD with and without pre-procedure oral administration of Simethicone ± N-acetylcysteine evaluating visibility as good or excellent in number during the procedure. In the random effects model analysis using the statistical software Review Manager 5.3, the use of Simethicone ± N-acetylcysteine was associated with improved (OR, 0.43; 95% CI, 0.28, 0.68; z=3.65; P=0.0003) mucosal visibility. Four RCTs on 364 patients reported OGD with and without pre-procedure oral administration of Simethicone ± N-acetylcysteine evaluating visibility score in study group. In the random effects model analysis using the statistical software Review Manager 5.3, the use of Simethicone ± N-acetylcysteine was associated with improved (SMD, −1.66; 95% CI, −1.93, −1.40; z=12.25; P=0.00001) mucosal visibility score compared to no-Simethicone group.
Conclusions: The findings of current study on 1,099 patients successfully demonstrate that the pre-procedure oral administration of Simethicone ± N-acetylcysteine improves mucosal visualization and mucosal visualization score during OGD.},
