Summary

Smartphone-controlled patch electro-acupuncture (SCEA) showed no significant pain reduction during colonoscopy but was favored by over 90% of patients. This novel device is a safe option for pain relief in endoscopic procedures.

Area of Science:

Gastroenterology
Pain Management
Acupuncture Technology

Background:

Smartphone-controlled patch electro-acupuncture (SCEA) offers analgesic effects comparable to traditional acupuncture.
Limited English literature exists on SCEA's use for primary pain relief during colonoscopy.

Purpose of the Study:

To evaluate the efficacy of SCEA as a primary pain relief method during colonoscopy.
To assess SCEA's potential as an alternative to conventional sedation for colonoscopy pain.

Main Methods:

A randomized controlled trial involving 37 patients undergoing colonoscopy.
Patients were assigned to either SCEA or a placebo group, with rescue sedation available.
Pain intensity was measured using a Visual Analogue Scale (VAS), alongside analysis of sedation use and procedure duration.

Main Results:

The SCEA group reported a lower median pain score (4.6) than the placebo group (6.0), though this difference was not statistically significant (P=0.12).
Over 90% of patients expressed a willingness to use SCEA again for primary analgesia.
No adverse complications were reported with the use of SCEA during the study.

Conclusions:

SCEA is a safe modality for pain management during colonoscopy.
Despite not achieving statistical significance in pain reduction, SCEA demonstrates high patient preference and acceptance.
Further research may explore optimizing SCEA protocols for enhanced analgesic effects in endoscopic procedures.
