The goal of this clinical trial is to learn if transcutaneous electrical acupoint stimulation (TEAS), a non-invasive therapy that applies mild electrical current to specific points on the skin, can help patients undergoing endoscopic retrograde cholangiopancreatography (ERCP) better tolerate the procedure and experience fewer complications related to sedation. It will also explore the underlying neuro-endocrine-immune mechanisms by measuring changes in serum biomarkers.\n2. The main questions the study aims to answer are:\n\n(1)Does TEAS reduce the incidence of sedation-related adverse events (such as low blood oxygen, low blood pressure, or breathing problems) during ERCP? (2)Does TEAS improve patient comfort and reduce the need for additional sedative medications during the procedure? (3)Does TEAS lead to faster recovery and higher patient and physician satisfaction? (4) Does TEAS modulate the neuro-endocrine-immune network, as reflected by changes in serum β-endorphin, cortisol, TNF-α, and IL-6 levels?\n\n3.Researchers will compare two approaches:\n\n1. Active TEAS: Electrical stimulation at specific points on the legs and arms before and during ERCP.\n2. Sham TEAS: Pads placed on the same points but no electrical stimulation delivered (the device appears active).\n\n4.All participants will receive standard conscious sedation with meperidine and diazepam, which is commonly used for ERCP in many centers. Participants will be randomly assigned to one of the two groups. The study will measure sedation-related complications, pain levels, medication requirements, recovery times, satisfaction scores, and changes in serum biomarkers (β-endorphin, cortisol, TNF-α, IL-6).",[75,76,77,78],"Endoscopic Retrograde Cholangiopancreatography","Conscious Sedation Adverse Event","Procedural Pain","Sedation-related Complications",[80,81,82,83,84,85,86,87,88,89,90],"Transcutaneous Electrical Acupoint Stimulation","ERCP","Conscious Sedation","Diazepam","Sedation-Related Adverse Events","Acupuncture","Non-Pharmacological Intervention","Neuro-endocrine-immune Mechanisms","Inflammatory Cytokines","Cortisol","β-endorphin","NOT_YET_RECRUITING","2026-06-14",{"date":94,"type":95},"2026-06-16","ACTUAL",{"date":97,"type":69},"2026-09-01",{"date":99,"type":69},"2027-10-01",{"name":5,"class":6},1]
