Abstract
BackgroundPostprandial distress syndrome (PDS) has a considerable impact on quality of life. Our previous pilot trial suggested that acupuncture might be a potential treatment option for PDS. We will conduct this large trial to determine the efficacy of acupuncture versus sham acupuncture for PDS.Methods/designA total of 280 eligible patients who meet the Rome IV criteria for PDS will be randomly allocated to either the acupuncture group or the sham acupuncture group. Each patient will receive 12 sessions over four weeks. The primary outcomes will be the response rate of overall treatment effect (OTE) and the elimination rate of all three cardinal symptoms (postprandial fullness, upper abdominal bloating, and early satiation) at four weeks after randomization. Secondary outcomes will include assessments of the severity of dyspepsia symptoms and disease-specific quality of life at weeks 4, 8, and 16 after randomization. All patients who receive randomization will be included in the intent-to-treat analysis.DiscussionThe finding of this trial will provide high-quality evidence on the efficacy of acupuncture for treatment of PDS. Results of this research will be published in peer-reviewed journals.Trial registrationISRCTN Registry, ISRCTN12511434. Registered on 31 March 2017.
Highlights
Postprandial distress syndrome (PDS) has a considerable impact on quality of life
Functional dyspepsia (FD) is subdivided into postprandial distress syndrome (PDS), characterized by postprandial fullness and early satiation, and epigastric pain syndrome (EPS), characterized by epigastric pain and burning [1]
PDS is associated with motility dysfunction and impaired gastric accommodation, while EPS is associated with a high prevalence of hypersensitivity to gastric distension [13]
Summary
PDS impacts patients’ QoL and causes a financial burden for society This large trial will evaluate the efficacy of acupuncture versus sham acupuncture in improving the symptoms of PDS. This trial meets the methodological demand of adequate randomization and allocation concealment, blinding of patients, outcome assessors, and statisticians. At the end of this trial, we hope the results will provide more reliable evidence and clarify the value of acupuncture as a treatment for PDS. Trial status This trial is currently recruiting patients.
