Abstract

A total of 6003 participants were analyzed in twelve randomized controlled studies.

  • There was no significant difference in overall adenoma detection rate (ADR) between groups with and without simethicone.
  • The right-side ADR also showed no significant difference between the two groups.
  • One study indicated that the addition of simethicone led to an increase in adenomas detected per patient (2.20 ± 1.36 vs 1.63 ± 0.89).
  • Meta-regression analysis suggested that a baseline ADR of less than 25% was linked to a notable benefit from oral simethicone.
  • The number needed to treat to observe a benefit in adenoma detection was 15.
  • Oral simethicone improved bowel preparation quality in the analyzed studies.
