title: [The clinical manifestation of duodeno-gastroesophageal reflux (DGER) in the children and adolescents].
abstract: The development of the new techniques and methods enabled to investigate the role of duodenal reflux in the pathogenesis of gastroesophageal reflux disease (GERD) therefore there is a need to establish the most common symptoms occurring in patients with duodenal reflux.
  
  
  OBJECTIVE
  To determinate the type of manifestation and the prevalence of duodeno-gastroesophageal reflux in children and adolescents confirmed in Bilitec 2000 method.
  
  
  METHODS
  59 patients (37 girls, 22 boys) aged 7-17 years (mean 14.7) with the symptoms of GER there were divided into 2 groups: subgroups: A--18 children with confirmed duodeno-gastroesophageal reflux in Bilitec 2000TM method and B--control consisted of 15 children with short stature referred to endoscopy due to celiac disease exclusion. In accordance to the endoscopic finding there were selected 3 subgroups: 20 patients with duodenal reflux, 19 patients with esophagitis and 20 children presenting those both disorders simultaneously. In all patients from group B the endoscopy, Bilitec 2000 and esophagitis pH metric findings haven't showed any abnormality.
  
  
  RESULTS
  The most common complain--in 16 (88.89%) patients was recurrent and/or chronic abdominal pain, next- heartburn in 12 (66.67%), vomits and/or regurgitations in 10 (55.56%) children.
  
  
  CONCLUSIONS
  The clinical manifestation of duodenal reflux was very much alike as in acid gastroeophageal reflux in the examined group. Therefore the functional gastrointestinal tract examinations have to be included in the diagnostic procedure.
