Abstract [en]

The nature of pancreatic acinar metaplasia (PAM) in the gastro-oesophageal junction (GOJ) remains obscure. We aimed to estimate its prevalence and investigate into its risk factors in a population-based series of first-time endoscopy patients. We investigated consecutive patients, endoscoped for the first time, representing defined catchment area populations. Biopsies were taken immediately below the GOJ and from the distal oesophagus. Endoscopy room-based cross-sectional clinical data were supplemented with exposure data from 160 population controls. Associations, expressed as odds ratios (OR), were modelled with multivariable logistic regression. A subsample of 26 patients underwent oesophageal pH monitoring. Among 644 patients (mean age 53 years, 43% men), PAM was found in 121 patients (19%), exclusively above the GOJ in 40 (6%), below GOJ in 67 (10%), and both above and below GOJ in 14 (2%). PAM exclusively above the GOJ and PAM exclusively below the GOJ were both borderline associated with age (2% increase in prevalence per year). PAM exclusively above the GOJ was significantly associated with female gender (OR 2.8, 95% CI 1.3-6.3) and presence of Helicobacter pylori immediately below the GOJ (OR 2.6, 95% CI 1.3-5.4). Out of 21 patients with Barretts oesophagus (BO), 8 (38%) had PAM above the GOJ. The mean value for percentage time with oesophageal pH andlt; 4.0 was 7.3% (95% CI 4.3-10.2%) among patients who had PAM above the GOJ (reference value 3.4%). Pancreatic acinar metaplasia might be an age-dependent lesion, associated with H. pylori, female gender and gastro-oesophageal reflux if located above the GOJ.
