[Morphological changes in esophageal mucosa in children with overweight]

In present work we studied the morphological features of the esophageal mucosa in 63 children with endoscopic diagnosis of the distal esophagitis having overweight and normal weight of a body. The biopsies were taken at level of 3 cm above a Z-line and at level of 1 cm above a Z-line. Dystrophic and dysregenerative changes were revealed at the majority of children and half of children had inflammatory changes of the esophageal mucosa regardless of weight of a body. These changes are more pronounced at level of 1 cm above a Z-line, their occurrence decreases with a distance from low esophageal sphincter. We used the pathology score system for assess the esophageal biopsies. According our scale we obtained following results: at level of 1 cm above Z-lines at 95% of children had the normal, minimum or mild features of esophagitis regardless of weight of a body. Morphological evidence of a reflux esophagitis was diagnosed statistically more often at level of 1 cm above Z lines in comparison with level of 3 cm above Z-lines (p < 0.01) as among children with overweight of the body (78 and 43% accordingly), and among children with normal weight of the body (78 and 35% accordingly). The obtained data will be allowed to avoid hyperdiagnostics of esophageal lesions in children.
