Abstract

To assess the value of serological biomarker testing as a substitute for esophagogastroduodenoscopy (EGDS) in pre-operative assessment of patients referred for bariatric surgery. Sixty-five obese patients with a mean age of 43 years (range: 21-65) and a mean body mass index (BMI) of 44 (range: 36-59) were studied. The patients were tested with a four-biomarker panel: pepsinogen I and II, gastrin-17 (basal and stimulated), andHelicobacter pylori(HP) antibodies (GastroPanel®, Biohit Oyj, Finland). On the basis of the biomarker test, the patients were classified into the HS (healthy stomach) group (n = 22) with the normal biomarker profile and the NHS (non-healthy stomach) group (n = 43). The classification of patients into HS and NHS was evaluated against the gold standard, i.e. EGDS with biopsies. The concordance (Cohen's kappa) between the biomarker test and gastric histology was 0.68; 95% CI 0.504-0.854, with an overall agreement of 84.6% (95% CI 73.9-91.4%). In the NHS group, all 43 patients had biopsy-confirmed chronic gastritis: 39 non-atrophic HP-gastritis, 4 atrophic antrum gastritis (AGA) of moderate severity.In the HS group only 6 patients had mild superficial H.pylori negative gastritis. Of the 22 HS subjects with the ...Continue Reading
