ARTICLE HIGHLIGHTS
Research background

Dyspepsia is a common clinical disorder. No studies have evaluated the diagnostic value of endoscopy in patients with no warning symptoms according to the Rome IV criteria.

Research motivation

Many studies have used warning symptoms to predict important endoscopic findings in patients with dyspepsia. However, there remains an uncertainty regarding the best initial management strategy for those patients with no warning features.

Research objectives

To evaluate the diagnostic value of endoscopy in dyspeptic patients with no warning symptoms.

Research methods

We performed a cross-sectional study of dyspeptic patients with no warning symptoms from April 2018 to February 2019.

Research results

The incidence of malignancy (0.9%) among dyspeptic patients with no warning symptoms was high. Moreover, male gender, body mass index > 25, epigastric pain and Helicobacter pylori infection were independently associated with significant endoscopic findings.

Research conclusions

According to the Rome IV standard, endoscopy is of high diagnostic value for dyspeptic patients with no warning symptoms in China. Dyspeptic patients should undergo gastroscopy regardless of the presence or absence of warning symptoms.

Research perspectives

Gastroscopy should be the initial management strategy for dyspeptic Chinese patients even in the absence of warning features. In the future, more controlled studies from multicenter samples will be needed to confirm this.
