Study Details

Study Description

Brief Summary

Functional abdominal bloating/distension (FAB/D) is a common functional bowel disorder that lacks effective treatment options. Transcutaneous electroacupuncture (TEA) as a new therapeutic method has great effect on functional gastrointestinal diseases such as functional dyspepsia and functional constipation. Research on TEA for FAB/D has not yet been explored.

Detailed Description

Functional abdominal bloating/distension (FAB/D) is a common functional bowel disorder that lacks effective treatment options. Rome IV was introduced in 2016. Studies have shown that bloating may affect about 30% general population and 96% of patients with functional gastrointestinal disorders (FGID).Transcutaneous electroacupuncture (TEA) as a new therapeutic method has great effect on functional gastrointestinal diseases such as functional dyspepsia and functional constipation. Research on TEA for FAB/D has not yet been explored. Thirty patients who fulfilled the Rome IV diagnostic criteria of FAB/D in the department of the second affiliated hospital of Xi'an jiaotong University.Inclusion criteria included: Symptoms of recurrent abdominal fullness, pressure, or a sensation of trapped gas (bloating), and/or measurable (objective) increase in abdominal girth (distention) more than 6 month;the main symptoms appeared in the past 3 months;Not taking related drugs; aged 18-65 years old;From January 2020 to December 2021; Sign informed consent. All patients were randomly assigned to 3 groups and received TEA at Zusanli (ST36) and Neiguan (PC6) with 3 diffrent parameter for 4weeks. The symptom severity score, abdominal girth, electrogastrogram (ECG) and orocecal transit time (OCTT) ,heart rate variability (HRV) ,rectal sensitivity and intestinal flora were recorded at baseline and after 2-week treatment, respectively. The symptom severity score was repeated at baseline and after 4-week treatment. Through the comparison of the index before and after TEA treatment to identify optimal stimulation parameters and explore its possible mechanism. The study was proved by the medical ethics committee of the Second Affiliated Hospital of Xi'an jiaotong University.

Arms and Interventions

Arm Intervention/Treatment
Experimental: One parameter TEA group for 4 weeks

Choose two acupoints,give 25Hz electrical stimulation for 4 weeks.

Device: Transcutaneous Electroacupuncture
give diffrent parameter TEA treatment for 4 weeks.

Experimental: Another parameter TEA group for 4 weeks

Choose two acupoints,give 100 Hz electrical stimulation for 4weeks.

Device: Transcutaneous Electroacupuncture
give diffrent parameter TEA treatment for 4 weeks.

Experimental: Sham-TEA group for 2 weeks, and the random TEA for the next 2 weeks.

Choose two non-acupoints,give 25Hz and 100Hz electroacupuncture stimulation respectively for the first 2 weeks. Then give supplement TEA treatment as described above for the next 2 weeks.

Device: Transcutaneous Electroacupuncture
give diffrent parameter TEA treatment for 4 weeks.

Outcome Measures

Primary Outcome Measures

  1. Symptom improvement rate [after 1 month TEA treatment]

    the symptom severity score with VAS and abdominal girth measurements

  2. The percentage of the normal gastric slow waves in electrogastrograph [after 1 month TEA treatment]

    The percentage of the normal gastric slow waves in fasting 、fed states and the post-preprandial EGG power ratio

  3. Orocecal ransit time [after 1-month TEA treatment]

    the lactulose hydrogen breath test was used to evaluate the intestinal transit time and observe the presence or absence of excessive small intestinal bacteria

  4. Heart rate variability(HRV) [after 1-month TEA treatment]

    Assessment of autonomic function with heart rate variability

  5. Flora structure [after 1-month TEA treatment]

    an Illumina MiSeq Platform was used to sequence 16S ribosomal RNA (rRNA) gene of the total bacteria in fecal samples.

  6. Rectal sensitivity [after 1-month TEA treatment]

    Rectal threshold for gas and defecation

  7. Plasma gastrointestinal peptide level [after 1-month TEA treatment]

    CCK、SP、NPY、CGRP、Motilin
