title: [Assessment of duodenogastric reflux 24h variability in subjects with functional dyspepsia].
abstract: Symptoms of functional dyspepsia demonstrate significant variability, among others dependently on the time of the day and on consumed meals. The aim of the study was to find out whether duodenogastric reflux is observed in subjects with nonulcer (NUD) and dysmotor dyspepsia (DD) and whether its intensification changes within 24 h. Investigations comprised 25 subjects with NUD and 25 with DD, aged 19-43 years after exclusion of other diseases and H. pylori infection. The gastric content of bilirubin was registered with Bilitec 2000 Synectics Medical. Duodenogastric reflux episodes were observed in both groups but their intensification and 24h dynamics were differentiated. In subjects with DD total reflux index was significantly higher than in those with NUD (mean=18.0+/-9.5% and mean=6.3+/-4.1%; p<0.05). These differences were particularly visible in after meal (mean=21.2+/-7.9% and mean=10.4+/-6.6%; p<0.01) and night time (mean=8.7+/-3.6% and mean=2.9+/-0.9%; p<0.01). The results of the study indicate that bilimetry may be useful in differentiation of the form of dyspepsia and in selection of rational therapy.
