Abstract

Background and aim: The diagnostic evaluation and management of patients with chronic dyspepsia may differ geographically according to patient age, prevalence of Helicobacter pylori or parasitic infection, and risk of gastric cancer. The characteristics and appropriate investigation of Cambodian patients with dyspepsia have not previously been studied. The aim of this study was to investigate the characteristics of Cambodian patients with chronic dyspepsia, the yield of upper endoscopy in these patients, and the value of alarm features in identifying patients with organic causes of dyspepsia.

Methods: We conducted a retrospective, single-center study of 1231 adults with chronic dyspepsia who underwent upper endoscopy. We compared clinical characteristics, H. pylori prevalence, and endoscopic and histological findings of patients with functional or organic causes of dyspepsia. This study was approved by the National Ethics Committee for Health Research.

Results: The majority of patients had overlapping symptoms of epigastric pain/burning and postprandial fullness/early satiety (40.6%), followed by epigastric pain/burning alone (29.7%) and postprandial fullness/early satiety alone (29.7%). Organic lesions were diagnosed in 6.9% of patients. The overall prevalence of H. pylori infection was 46% and was similar in the three clinical subgroups. The sensitivity and specificity of alarm features for organic causes of dyspepsia were 14 and 96%, respectively. The majority of patients with gastric cancer were 40 years of age or older.

Conclusions: The majority of patients with chronic dyspepsia seen at our outpatient center were diagnosed with functional or H. pylori-associated dyspepsia. The presence of alarm features was not sensitive or specific for differentiating organic and functional dyspepsia.

Keywords: functional dyspepsia; gastric cancer; helicobacter pylori; upper endoscopy.
