August 28, 2026 updated by: Dr Nguyen Ngo Le Minh Anh MD, PhD, University of Science Ho Chi Minh City

Efficacy and Safety of Thread-Embedding Acupuncture as an Adjunct to Proton Pump Inhibitor Therapy in Patients With Gastroesophageal Reflux Disease and Liver-Stomach Stagnation-Heat Syndrome: A Randomized Controlled Trial

This study aims to evaluate the effectiveness of thread-embedding acupuncture combined with omeprazole in patients with gastroesophageal reflux disease (GERD) presenting with the traditional medicine pattern of Liver-Stomach constraint-heat. Participants will receive either thread-embedding acupuncture combined with omeprazole or the comparator treatment according to the study protocol. Clinical outcomes will be assessed to determine the effectiveness and safety of the intervention.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Active Comparator: Omeprazole
Participants receive omeprazole according to the treatment regimen specified in the study protocol.
Procedure: Thread-Embedding Acupuncture
Participants will receive acupoint catgut embedding in addition to standard treatment with omeprazole. Acupoint catgut embedding will be performed twice during the 4-week treatment period, at 2-week intervals. Sterile chromic catgut 3/0 will be embedded at Zhongwan (CV12), Shangwan (CV13), Xiawan (CV10), Zusanli (ST36), Tianshu (ST25), and Taichong (LR3) according to the standardized procedure. Participants will be monitored for 30 minutes after each procedure for adverse events.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change in GERD-Q Score
Time Frame: Baseline and 4 weeks
Gastroesophageal reflux disease symptoms will be assessed using the Gastroesophageal Reflux Disease Questionnaire (GerdQ). The total GerdQ score ranges from 0 to 18, with higher scores indicating more severe gastroesophageal reflux disease symptoms. Change in the total GerdQ score from baseline to 4 weeks will be assessed between the two study groups.
Baseline and 4 weeks

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Treatment Response Based on GerdQ
Time Frame: Baseline and weekly through 4 weeks
Treatment response will be defined as a reduction of at least 2 points in the total Gastroesophageal Reflux Disease Questionnaire (GerdQ) score from baseline. The total GerdQ score ranges from 0 to 18, with higher scores indicating more severe gastroesophageal reflux disease symptoms. The proportion of participants achieving treatment response will be compared between the two study groups.
Baseline and weekly through 4 weeks
Complete Symptom Resolution Based on GerdQ
Time Frame: 4 weeks
Complete resolution of typical gastroesophageal reflux disease (GERD) symptoms will be assessed using the Gastroesophageal Reflux Disease Questionnaire (GerdQ). The total GerdQ score ranges from 0 to 18, with higher scores indicating more severe GERD symptoms. Complete symptom resolution will be defined as a score of 0 for both the heartburn and regurgitation items of the GerdQ. The proportion of participants achieving complete symptom resolution at 4 weeks will be compared between the two study groups.
4 weeks
Change in Traditional Medicine Symptoms of Liver-Stomach Heat Stagnation Syndrome
Time Frame: Baseline and weekly through 4 weeks
Traditional medicine symptoms of Liver-Stomach Stagnated Heat syndrome will be assessed using a syndrome symptom score comprising two main symptoms (burning sensation and acid regurgitation) and six secondary symptoms (retrosternal pain, epigastric burning pain, epigastric fullness, belching or food regurgitation, irritability, and rapid hunger). Each main symptom is rated as absent, mild, moderate, or severe and scored 0, 2, 4, or 6 points, respectively. Each secondary symptom is rated as absent, mild, moderate, or severe and scored 0, 1, 2, or 3 points, respectively. The total score ranges from 0 to 30, with higher scores indicating greater syndrome severity. Change in the total syndrome score from baseline through 4 weeks will be compared between the two study groups.
Baseline and weekly through 4 weeks
Treatment Response Based on Liver-Stomach Stagnated Heat Syndrome Score
Time Frame: Baseline and 4 weeks
Treatment response for Liver-Stomach Stagnated Heat syndrome will be assessed using the percentage reduction in the total syndrome score from baseline. The efficacy index will be calculated as [(baseline score - post-treatment score) / baseline score] × 100. Clinical cure is defined as an efficacy index of at least 95%, markedly effective as 70% to less than 95%, effective as 30% to less than 70%, and ineffective as less than 30%. The proportion of participants classified as clinically cured, markedly effective, effective, or ineffective at 4 weeks will be compared between the two study groups.
Baseline and 4 weeks
Adverse Events Associated With Thread-Embedding Acupuncture
Time Frame: Throughout the 4-week treatment period
Adverse events associated with thread-embedding acupuncture will be monitored throughout the 4-week treatment period. Events of interest include local pain, bleeding, bruising, swelling, infection, allergic reactions, and other treatment-related complications. The number and proportion of participants experiencing at least one adverse event will be recorded and compared between the two study groups.
Throughout the 4-week treatment period
