BACKGROUND Music has been used to reduce stress and improve task performance during medical therapy.AIM To assess the effects of music on colonoscopy performance outcomes.METHODS We retrospectively reviewed patients who underwent colonoscopy performed by four endoscopists with popular music.Colonoscopy performance outcomes,such as insertion time,adenoma detection rate(ADR),and polyp detection rate(PDR),were compared between the music and non-music groups.To reduce selection bias,propensity score matching was used.RESULTS After one-to-one propensity score matching,169 colonoscopies were selected from each group.No significant differences in insertion time(4.97 vs 5.17 min,P=0.795)and ADR(39.1%vs 46.2%,P=0.226)were found between the two groups.Subgroup analysis showed that the insertion time(3.6 vs 3.8 min,P=0.852)and ADR(51.1%vs 44.7%,P=0.488)did not significantly differ between the two groups in experts.However,in trainees,PDR(46.9%vs 66.7%,P=0.016)and ADR(25.9%vs 47.6%,P=0.006)were significantly lower in the music than in the nonmusic group.CONCLUSION The current study found that listening to music during colonoscopy did not affect procedure performance.Moreover,it suggested that music may distract trainees from appropriately detecting adenomas and polyps.
