Slow‐wave photic stimulation relieves patient discomfort during esophagogastroduodenoscopy

Background and Aim:  Although pretreatment with a sedative drug is effective in relieving pain during esophagogastroduodenoscopy (EGD), such drugs can cause significant side‐effects. The aim of this study was to examine the effect of slow‐wave photic stimulation on discomfort and/or pain felt during EGD.
