RESUMO
Transcutaneous auricular vagus nerve stimulation(taVNS)is a non-invasive alternative treatment for vagus nerve stimulation.In the early stage,it was used to treat epilepsy,depression,blood pressure control,insomnia,and so on.After continuous exploration,it was gradually applied to the treatment of functional dyspepsia,irritable bowel syndrome,and other digestive system diseases.TaVNS is the stimulation of auricular branch of vagus nerve distributed in the receptive field of the external ear with a specific frequency of the current,which directly or indirectly affects the vagal tension and regulates the gastrointestinal nerve reflex,to achieve the purpose of treatment.The exact mechanism of taVNS is still unclear,but the results of research in the last decade indicate that taVNS has been used as an alternative or adjuvant treatment for drug therapy in many digestive system diseases.This article reviewed the progress of research on taVNS in the treatment of digestive system diseases.
