TEAS for Gastrectomy Recovery
Sponsor: The Affiliated Hospital of Qingdao University
Summary
The goal of this clinical trial is to learn if transcutaneous electrical acupoint stimulation (TEAS) works to help people recover faster after laparoscopic surgery for stomach cancer. TEAS is a treatment that uses small electrical pulses through sticky pads on the skin. It does not use needles. The main questions it aims to answer are: Does TEAS help people pass gas (a sign that the digestive system is waking up) sooner after surgery? Does TEAS help lower pain after surgery? Does TEAS reduce the need for extra pain medication after surgery? Researchers will compare two groups to see if TEAS works better than a sham (inactive) treatment. Group 1 (TA group) receives real TEAS after surgery. Group 2 (SA group) receives a sham treatment at the same time points. All participants will receive the same standard pain relief and recovery care after surgery. Participants will: Be randomly assigned (like flipping a coin) to one of the two groups. Receive TEAS or sham treatment for 30 minutes starting 2 hours after waking from anesthesia, and then once daily each morning on the first 3 days after surgery. Rate their pain on a 0-10 scale at 6, 12, 24, 48, and 72 hours after surgery. Complete quality-of-life and fatigue questionnaires before surgery, on day 4 after surgery, and 30 days after surgery. Have a follow-up visit or phone call 30 days after leaving the hospital. This study includes 104 adults aged 18 to 80 years who are scheduled to have laparoscopic surgery for stomach cancer at 8 hospitals in Shandong Province, China.

Interventions
Transcutaneous Electrical Acupoint Stimulation
TEAS is delivered using a standardized electroacupuncture device (SDZ-V, Suzhou Medical Products Factory) with a dense-disperse wave (20 Hz alternating with 100 Hz, 5s/10s duty cycle, pulse width 0.2 ms ± 30%). Four bilateral acupoints are selected: Hegu (LI4), Neiguan (PC6), Zusanli (ST36), and Shangjuxu (ST37). The intensity is individually titrated to the maximal tolerable threshold using a dual-threshold method.
Sham Transcutaneous Electrical Acupoint Stimulation
Sham TEAS uses the same SDZ-V device with identical appearance, indicator lights, and audible signals. The internal output leads are disconnected to deliver no electrical current. The operator performs the same procedural steps, including simulated dial adjustments, to maintain participant blinding.
