[Gastric mucosa as a target in duodenogastric reflux: assessment of lesions with the system of indices].
OBJECTIVE
To characterize gastric mucosa lesion in patients with duodenogastric reflux (DGR) using an original system of indices evaluating general pathological processes in gastric mucosa.


METHODS
The trial enrolled 109 patients with chronic gastritis (CG) in combination with opisthorchiasis. These were divided into 2 groups: CG patients with DGR (group 1, n = 58), CG patients free of DGR (group 2, n = 51). Thirty patients with chronic acalculous cholecystitis served control. All the patients have undergone fibrogastroduodenoscopy with biopsy from the antral part of the stomach and its body. To detail morphological picture of the gastric mucosa a number of additional indices were used characterizing exudative inflammation, productive inflammation, atrophic, sclerotic, immunopathological, dysregeneratory processes.


RESULTS
Semiquantitative analysis of gastric mucosa in chronic opisthorchiasis patients with DGR by the above indices showed a significant prevalence of exudative (p < 0.05) and productive (p < 0.01) inflammations in the antrum over those in the gastric body. Comparison of the indices in the patients with and without DGR revealed significant differences in activity of exudative inflammation (p < 0.05), dysregeneratory (p < 0.05) and atrophic (p < 0.001) processes in gastric antrum and dysregeneratory and atrophic processes in the gastric body (p < 0.01).


CONCLUSIONS
The indices contribute to more precise assessment of structural shifts occurring in gastric mucosa which is the target for DGR.
