Objectives

Narrative objectives1

Primary sclerosing cholangitis (PSC) is a progressive chronic intrahepatic biliary stasis disease with poor prognosis caused by fibrous stenosis of intrahepatic and extrahepatic bile ducts of unknown cause. On the other hand, the vagus nerve plays a role in regulating inflammatory responses and immune function, in addition to modulating many physiological responses, making vagus nerve stimulation a promising new treatment for a variety of diseases. Recently, transcutaneous auricular vagus nerve stimulation (taVNS) has been investigated. In this study, we aim to evaluate the efficacy, safety, and incidence of adverse events in improving liver injury/serum hepatobiliary enzyme abnormalities by administering taVNS to patients with PSC.
