Clinically Significant Endoscopic Findings in a Multi-Ethnic Population With Uninvestigated Dyspepsia

Abstract

The proportion of clinically significant endoscopic findings (CSEF) in dyspepsia affects the initial management of this condition. With the changing epidemiology of organic upper gastrointestinal diseases in Asia, current data on CSEF remains uncertain. A cross-sectional study of consecutive adult patients attending an open access endoscopy list for the primary indication of dyspepsia was conducted. Independent epidemiological and clinical factors for CSEF were determined prospectively. Data for 1167/1208 (96.6 %) adults (mean age 49.7 ± 15.9 years, 42.4 % males, ethnic distribution: 30.5 % Malays, 36.9 % Chinese and 30.8 % Indians) were analysed between January 2007 and August 2008. Three-hundred and eight (26.4 %) patients were found to have CSEF, most often those with age ≥45 years (30.3 vs 19 %, P < 0.0001), male gender (34.1 vs 20.7 % female, P < 0.0001), lower education levels (i.e. primary or no education), smoking (36.7 vs 24.9 %, P = 0.003), H. pylori infection (40.6 vs 21.8 %, P < 0.0001), and duration of dyspepsia ≤5 months (32.8 vs 24.4 %, P = 0.006). Age ≥ 45 years (OR 1.82, 95 % CI = 1.38-2.48), male gender (OR 1.84, 95 % CI = 1.53-2.59), H. pylori infection (OR 2.36, 95 % CI = 1.83-3.26), and duration of dyspepsia ≤5 months (OR 1.44, 95 % CI = 1.13-2.03) were subsequently identified as independent risk factors for CSEF. CSEF are found in 26.4 % of Asian adults with uninvestigated dyspepsia. Duration of symptoms <5 months, among other recognised factors, is predictive of CSEF.
