Effect of Transcutaneous Auricular Vagal Nerve Stimulation on Chronic Constipation
February 9, 2023 updated by: Yanglin Pan, Air Force Military Medical University, China
Effect of Transcutaneous Auricular Vagal Nerve Stimulation on Chronic Constipation: A Randomized Controlled Trial
The worldwide prevalence of chronic constipation (CC) is 15%, and women are more likely to develop the disease than men.
CC have a significant impact on quality of life and increase the burden of national health insurance.
The conventional medication treatments are primarily symptom-specific and have limited efficacy.
Previous small sample study had shown the therapeutic potential of transcutaneous auricular vagus nerve stimulation (taVNS) for irritable bowel syndrome with constipation (IBS-C).
The aim of this study was to investigate whether taVNS could improve defecation condition and constipation symptoms in patients with CC.

---|---|
EXPERIMENTAL: Treatment group
patients will receive taVNS at left tragus for four weeks.

Patients will receive taVNS (device produced by Xi'an Bashui Health Technology Co., Ltd) thirty minutes twice a day in the morning and the night for four weeks (duty circle: 30s "on" periods and 30s "off" periods; frequency: 25 Hz; amplitude of 0-2 mA at the maximum level that the patient could tolerate; pulse width: 0.5ms)
Bisacodyl or glycerin enemas can be used in patients who do not have a bowel movement for more than 3 days.
