[Clinico-endoscopic characteristics of gastroduodenal Campylobacter infection in children].

During diagnostic esophagogastroduodenoscopy, 104 children aged 6 months to 14 years were subjected to spot biopsy of the mucous membrane of the antral part of the stomach and duodenal bulb with a purpose of subsequent studies for Campylobacter pyloris (C. P.) including primary microscopy, the screening-urease test and culture isolation followed by its identification according to all the necessary biochemical tests. C. P. were detected in 50% of the children examined including 9 out of 12 patients suffering from ulcer disease of the duodenum. It was shown that the C. P. incidence noticeably rose with an increase of the period of the gastroenterologic anamnesis. The characteristic clinical and endoscopic signs of the illness were defined, associated with most or less probable C. P. isolation. It has been established that the findings of the screening-urease test cannot form the basis for the final diagnosis of pyloric campylobacteriosis in children.
