    AimTo determine predictors of insufficient effectiveness of proton pump inhibitors based on the parameters of 24-hours pH-impedance and features of motor function of the esophagus in patients with Barrett's esophagus.Materials And Methods17 patients with histologically verified Barrett's esophagus undergoing acid-suppressive therapy were examined. All patients underwent 24-hours pH-impedance and high-resolution esophageal manometry.ResultsAccording to daily pH-impedance, group 1 consisted of 11 patients with an adequate response to antisecretory therapy, group 2 6 patients with insufficient effectiveness of antisecretory therapy, 5 of whom had no clinical manifestations. The total number of reflux averaged 52 and 91, respectively, in groups 1 and 2. The average number of acid reflux in group 1 was 4.36, in group 2 40.5. The average number of non-acid reflux prevailed in patients of group 2, averaging 58, compared with group 1, where the average was 47. According to the results of high-resolution esophageal manometry, when assessing the structure and function of the esophageal-gastric junction, violations were detected in 6 out of 17 patients. Disorders of the motor function of the thoracic esophagus were detected in 10 out of 17 patients. The tone of the lower esophageal sphincter in group 1 patients was significantly higher in comparison with patients in group 2.ConclusionA number of patients with Barrett's esophagus have insufficient effectiveness of antisecretory therapy, which may not manifest itself clinically and thereby increase the risk of progression. There was a tendency to more frequent motor disorders in the group with insufficient effectiveness of antisecretory therapy, as well as significantly lower tone of the lower esophageal sphincter, which may be a potential predictor of suboptimal effectiveness of antisecretory therapy.
