Differences In quality of life between patients with functional dyspepsia after esophagogastroduodenoscopy with empiric treatment and placebo

Functional dyspepsia is a common health problem found in society. Few of multifactorial aspects which become the underlying cause of functional dyspepsia are anxiety and psychosocial problem. Esophagogastroduodenoscopy (EGD) examination can display exact information to patient with functional dyspepsia and expected to increase patient's quality of life. It is still necessary to evaluate the advantages of EGD examination in improving patient's quality of life.A Randomized double blind controlled trial was conducted to compare between group of patients who have been given an empiric treatment(Proton pump inhibitor and prokinetic agents) and other who have been given a placebo for 2 weeks after underwent EGD examination in patients with functional dyspepsia. The primary outcome of this study is the decrease of NDI-SF score on both of groups at the end of study.A total of 42 patients (22 in EGD+placebo group [Group I] and 20 in EGD + treatment group[Group II]) were enrolled. NDI-SF score decreased significantly in both groups, Group I (26.23±8.43 vs 19.59±7.62, P=0.001) and Group II (27.32±7.57 vs 19.21±5.68, P=0.002), 15 days after underwent EGD examination. NDI-SF score improvement between two groups 15 days after EGD was not significantly different (P=0.814). This study showed improvement in quality of life of patients whom diagnosed with functional dyspepsia after EGD examination in both groups. This improvement was not significantly different between two groups and showed the placebo effect of EGD on functional dyspepsia patient.
