Could a gentle electric zap at key points make emergency gut exams easier for liver patients?
NCT ID NCT07106658
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether a mild electrical stimulation at specific acupoints (TEAS) helps people with cirrhosis tolerate an urgent endoscopy for suspected variceal bleeding. 180 patients were split into three groups: active TEAS, sham TEAS (electrodes but no current), or standard endoscopy alone. The goal was to see if TEAS improves procedural success and reduces discomfort.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Transcutaneous electrical acupoint stimulation (TEAS) using a Hwato SDZ-III device
- What this could lead to
- If it works, this could offer a simple, drug-free way to make urgent endoscopy more comfortable and successful for people with cirrhosis.
- What could go wrong
- This is a small, completed trial with 180 participants. The sham group may also show benefit, and results may not apply to all patients or settings.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
1\. Inclusion Criteria: 1. Patients aged 18-80 years with suspected or confirmed esophagogastric variceal bleeding 2. Confirmed cirrhosis (any etiology/Child-Pugh class) 3. Scheduled for urgent endoscopy as soon as possible following hemodynamic stabilization 4. Ability to provide written informed consent (directly or through legally authorized representative) 2\. Exclusion Criteria: 1. Hepatic encephalopathy ≥ Grade II 2. Cognitive impairment or severe anxiety disorders preventing valid assessment 3. Hemodynamic instability post-resuscitation (systolic BP \<90 mmHg) 4. Skin lesions at acupoint sites 5. Presence of electrical implants (e.g., pacemakers) 6. Allergies to TEAS electrodes or emergency medications 7. Pregnancy or lactation 8. History of long-term opioid use (\>3 months) 9. Inability to provide informed consent 10. Prior TEAS or acupuncture experience (to maintain blinding integrity) 11. Participation in another interventional trial within 30 days 3\. Dropout Criteria: 1. Severe adverse events requiring immediate termination (anaphylaxis, hemodynamic collapse, oxygen desaturation \<85%) 2. Life-threatening complications during endoscopy (esophageal perforation, cardiac arrest) 3. Inability to complete full esophagogastroduodenoscopy due to patient intolerance or technical failure 4. Voluntary withdrawal by participant or legal representative
