Endoscopic changes in the gastrointestinal tract in children with helicobacteriosis

Background: All over the world, chronic gastroduodenal pathology (CGDP) occurs in children from 3.2% to 52% and takes 2nd place after diseases of the respiratory system. The main pathogen is Helicobacter pylori (HP), and the problem of studying endoscopic changes in the stomach and duodenum in n these children remains relevant. This study investigated changes observed by esophagogastroduodenoscopy (EGD) examination of the mucous layer of the upper digestive tract in children CGDP and its features in HP infection. Methods: A total of 128 children aged 6 to 15 years exhibited CGDP. All patients underwent EGD, with a description of the visible mucous membrane of the stomach and duodenum. Research on HP infection was carried out by two methods: a breath test and an immunochromatographic faecal test. Results: It was noted that the rate of Helicobacter pylori infection was higher in patients with ulcerative lesions of the gastrointestinal tract than in patients with inflammatory processes (on average 1: 0.6). A high prevalence of gastroesophageal and duodenogastric reflux was revealed in patients with HP infection. In children with HP infection, atrophic lesions of the antrum and body of the stomach, bulbar and distal duodenum prevailed. Conclusions: Gastric ulcers and duodenal ulcers developed 94% more often in children with HP infection than in HP-uninfected patients (P<0.005), and atrophic changes in the mucous layer of the stomach and intestines were 4 times more common against the background of the more common gastroduodenal (by 77.6%) and duodenogastric (by 67.4%) reflux.
