The aim of this thesis is to present a complex information about the etiology, diagnosis and treatment of gastroesophageal reflux disease (GERD) and to further elucidate the function of the diaphragm as the external esophageal sphincter and as a part of the antireflux barrier in patients with GERD. The study included 87 patients with verified GERD. Patients were subjected to a set of postural and respiratory maneuvers - caudal position of chest, abdominal breathing and measuring of the maximal respiratory pressures, all performed on the basis of tolerance to position and maneuver. The high-resolution manometry (HRM) was chosen to record the changes in pressure in the lower esophageal sphincter and for the measurement of respiratory pressures was used the spirometric system MasterScope. It was found that postural and respiratory maneuvers, that activate the diaphragm, increase the pressure in the EGJ. The most significant increase occurred during the maximal inspiratory maneuver, which increased LES pressure up to 261.2 %. The results also show that patients with GERD have reduced the strength of respiratory muscles, especially inspirational muscles. Reaching only 66.5 % of predicted PImax. We have demonstrated that patients with GERD have significantly lower diaphragm muscle strength, what...
