ABSTRACT

Objective To investigate the relationship between the endoscopic characteristics of chronic gastritis,duodenitis,peptic ulcer and their histopathologic findings in children,and explore the relationship between Helicobacter pylori(Hp) infection and the severity of histopathologic changes of gastroduodenal mucosa in children. Methods Three hundreds and sixty-six children with chronic upper gastrointestinal symptoms who were examined by gastroscopy were enrolled.The gastric and duodenal mucosal biopsy specimens of all the patients were studied histopathologically. ResultsTypes of chronic gastroduodenal diseases in all these patients were chronic gastritis(n=206,56.3%),chronic gastritis combined with duodenitis(n=112,30.6%),chronic gastritis combined with peptic ulcer(n=48,13.1%).There was chronic inflammation in gastric mucosa and duodenal bulb mucosa in all the cases examined by histopathologic examination.Hp infection was found in 106 cases(28.96%).The gastric mucosal inflammation was more severe in those with Hp infection than those without(P0.05).The were significant differences in the incidences of inflammation activity,atrophia and nodulus lymphaticus of gastric mucosa between those with Hp infection and those without(P
