Background. The problem of peptic ulcer disease (PUD) in children has a medical and social significance, which is determined by its considerable prevalence in the most important periods of growth and development of the child. The purpose of the study was to evaluate the rates of regional bleeding in the abdominal trunk of children with PUD. Materials and methods. The study enrolled 45 children with PUD aged 7–18 years (basic group) and 50 children of the relative age without gastrointestinal pathology (comparison group). The study was conducted according to gene­rally accepted methods in the clinic. Ultrasound of regional blee­ding (internal diameter of the vessel, linear blood flow velocities, peak systolic blood flow velocity, final diastolic blood flow velocity, volumetric bleeding velocities (Vbv), calculated resistance index (RI)) was performed in children with ulcers in the acute phase, red and white scars stages, and in 6 months after ulcer scarring. Results. It was found that in healthy children after eating the diameter of the abdominal trunk changes slightly — ±8–14 % from baseline. Changes in the linear velocity of blood flow after meals in healthy children are characterized by high variability and multidirec­tional dynamics. IR fluctuations do not exceed ±10 %, and in most (86.1 %) patients its values decrease. In the postprandial period Vbv increases. In 30 minutes after a standard breakfast, healthy children experienced an increase in the diameter of an abdominal trunk. In the white scar phase, a statistically significant (t = 2.97, p < 0.01) decrease in the diameter of the abdominal trunk, a decrease in volumetric blood flow (t = 3.19, p < 0.05) by 20.6 %, and a simultaneous increase in IR (t = 2.89, p < 0.01) were determined. Conclusions. The changes in the hemodynamics of the abdominal trunk can be a predictor of both ulcer development and possible exacerbation of the disease, and therefore the scheme of examination of patients with PUD should include a dynamic hemodynamic examination of the abdominal vessels that feed the gastroduodenal area.
