The state of motor function of the gastrointestinal tract in children with gastroesophageal reflux disease A.S.

Objective. To assess the specificities of myoelectrical activity of the gastrointestinal tract in children with gastroesophageal reflux disease.
Patients and methods. We examined 60 healthy children aged 7 to 16 years (mean age 13.1 ± 2.2 years), who were assessed as belonging to health groups I or II, in order to establish normal parameters of peripheral electrogastroenterography. Also, 55 children aged 7 to 17 years (mean age 13.0 ± 2.6 years) diagnosed gastroesophageal reflux disease were examined in order to study motility disorders of the gastrointestinal tract. Myoelectrical activity of the gastrointestinal tract in children of both groups was assessed by the method of peripheral electrogastroenterography according to the standard technique.
Results. Normal parameters of the motor function of the gastrointestinal tract were determined: electrical activity (Pi/Ps), %, rhythmicity coefficient (Kritm), correlation ratio (Pi/Pi+1). In children with gastroesophageal reflux disease, high electrical activity following fasting was recorded on the duodenal frequencies, as well as dysrhythmia of motility of the upper digestive tract, nonpropulsive «pendulous» contractions of all parts of the gastrointestinal tract, inadequate response of the stomach and duodenum to food stimulation.
Conclusion. Peripheral electrogastroenterography is a noninvasive safe method of diagnosis, it might be recommended as one of the methods for determination of motility disorders in patients with gastroesophageal reflux disease in order to make further pharmaceutical correction of diagnosed disorders.
Key words: gastroesophageal reflux disease, children, peripheral electrogastroenterography, electrical activity of GIT.
