Intradermal Needle Therapy Relieves Postoperative Pain After Endoscopic Submucosal Dissection (ESD)

Brief Summary

The objective of this clinical trial is to explore the analgesic effect of intradermal needle therapy on patients after gastric endoscopic submucosal dissection, and evaluate the safety of intradermal needle therapy. The primary questions it aims to address are: 1. What is the incidence of moderate-to-severe pain after gastric endoscopic submucosal dissection (ESD)? What is the incidence of moderate-to-severe pain after treatment with intradermal needle therapy? 2. What adverse reactions do patients experience after treatment with intradermal needle therapy? 3. Does intradermal needle therapy alleviate postoperative pain in patients undergoing gastric endoscopic submucosal dissection (ESD)? Patients will: 1. Postoperatively, patients were randomly assigned to a treatment group and a control group. In addition to conventional treatment, patients in the treatment group received intradermal needle therapy within 1 hour after surgery. Bilateral Hegu (LI4) and Zusanli (ST36) acupoints were selected for this therapy. Patients were positioned in a supine position, and after locating the acupoints, the skin of the acupoint areas was sterilized with 75% ethanol using a medical cotton swab. The intradermal needle was then removed along with the adhesive tape, inserted into the acupoints, and pressed every 4 hours for approximately 60 presses each time, excluding nighttime sleep. The pressure was applied until an acid, swelling, or numb sensation was felt at each acupoint. The intradermal needle therapy was administered only once and continuously pressed for 3 days. The control group received conventional postoperative treatment. 2. Researchers will record the incidence of moderate-to-severe pain within 72 hours postoperatively using the VAS pain score (no pain: 0 points, mild: 1-3 points, moderate: 4-6 points, severe: 7-10 points). VAS pain scores and Simplified McGill Pain Questionnaire (SF-MPQ) scores will be assessed at 1h, 6h, 12h, 24h, 48h, and 72h postoperatively. The use of analgesic medications will also be noted. Preoperative and postoperative SAS and SDS scores will be documented, along with postoperative recovery details such as length of hospital stay , and surgical complications (such as fever, bleeding, and perforation). Additionally, the safety evaluation of intradermal needle therapy will include monitoring for adverse events such as dizziness, skin irritation, skin breakage, infection, hematoma, local pain or discomfort at the puncture site, or needle breakage. 3. The baseline characteristics of patients will be recorded, and factors associated with postoperative pain after gastric endoscopic submucosal dissection (ESD) (including demographic data, clinicopathological features, surgical conditions, etc.) will be analyzed.
