What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting This study
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study tests whether transcutaneous electrical acupoint stimulation (TEAS) — a needle-free treatment that sends mild electrical pulses through sticky pads on the skin — can help people recover faster after laparoscopic surgery for stomach cancer. Researchers are comparing three groups: one receiving TEAS before, during, and after surgery; one receiving it only after surgery; and one receiving a sham (inactive) treatment at all times. The main goals are to see if TEAS helps people pass gas sooner (a sign the digestive system is waking up) and reduces pain and the need for extra pain medication.

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 the Hwato SDZ-V device, applied to four acupoints (LI4, PC6, ST36, ST37) with a dense-disperse wave at 2/100 Hz.
What this could lead to
If it works, this could offer a drug-free way to speed up bowel recovery and reduce pain after stomach cancer surgery.
What could go wrong
This is a mid-sized trial testing timing of treatment, and results may not apply to other surgeries or populations. The sham control helps, but patient expectations could still influence outcomes.
