Features of the diagnosis of local chemical burns of the gastric mucosa in military conscripts

To improve the quality of diagnosis of local chemical burns of the gastric mucosa, the results of primary esophagogastroduodenoscopy and histological examination of its biopsy specimens were studied in 22 conscripts (main group) who used dry aggressive chemicals to simulate diseases of the upper digestive tract in the period from 2006 to 2017. The control group included conscripts (n=20) with acute deep erosion and acute gastric ulcer. Established endoscopic (the presence of a large defect in the mucous membrane of the «loop» of less deep damage, spreading toward fluid movement in the stomach; a decrease in the depth of the burn ulcer or erosion from the center to the edges; localization of a local chemical burn of the gastric mucosa on the greater curvature of the distal third of the body or antrum of the stomach) and histological (the presence of a scab on the surface of the defect; mild inflammatory infiltration of the mucous membrane with pronounced necrotic and necrobiotic changes in the integumentary-pit and glandular epithelium) differential diagnostic signs of a local chemical burn of the gastric mucosa.
