Objectives and methods: We analyzed upper endoscopic and histological findings in 3 cohorts of children undergoing upper gastrointestinal endoscopy over a 10-year period. Five hundred seventy-nine patients were identified, with 244 (42%), 199 (35%), and 136 (23%) in the 2011, 2015, and 2019 cohorts, respectively. The most common symptoms and signs were abdominal pain, vomiting, failure to thrive, and diarrhea.
Results: The number of patients who had histological evidence of chronic gastritis increased from 2011 (n = 70, 29%) to 2015 (n = 106, 53%) and 2019 (n = 92, 68%; P < .001). The prevalence of "normal" endoscopic gastric findings was higher in controls (n = 247, 90%) compared to cases (n = 201, 76%; P < .001). There was a small but statistically significant difference in endoscopic esophageal grading (P = .008) over time, with lower grades being more prevalent in 2011 compared to 2015 (P = .026) and 2019 (P = .001). Crude comparisons of the predictors (sex, weight percentile, payor type, month of endoscopy, symptom duration, PPI exposure, and endoscopic stomach findings) yielded no difference between cases and controls.
Conclusions: There has been a significant rise in the prevalence of mild chronic gastritis or non-specific gastritis over the last decade in our population.
