The case describes the surgical treatment of a patient with a false aneurysm of the proximal anastomosis of the Sano shunt in a patient with hypoplastic left heart syndrome midterm after bidirectional cavo-pulmonary anastomosis. The diagnostic algorithm included a physical examination, echocardiography, and multispiral computed tomography. Surgical treatment included closure of the right ventricular defect and removal of blood clots from the cavity of the false aneurysm.

The aim of the work – to study the regularity of changes in the level of acidity, H.pylori infection and the clinical manifestation of heartburn in patients with chronic nonatrophic gastritis before and after treatment that did not include proton pump inhibitors.Material and methods. We have analyzed the results of a comprehensive examinationof 38 patients with chronic non-atrophic gastritis, suffering from heartburn, before andafter treatment that did not include proton pump inhibitors. Comprehensive examinationbefore treatment included a step-by-step pH-metry, esophagogastroduodenoscopy,double testing for Helicobacter pylori infection (urease test and microscopy of the stainedsmears-prints) using mucosal biopsy specimens from 4 topographic zones of the stomach;histological examination of the gastric mucosa, material for which was taken from thesame areas, and HELIC test. After the treatment, pH-meter control and HELIС test wereperformed.Results. When carrying out a comparative characteristic of the obtained data, ithasbeen found that the average level of acidity after the treatment increased from moderateminimal hypoacidity to pronounced absolute hyperacidity, while the average level ofcontamination of the gastric mucosa by H. pylori infection, tracked by the level of theHELIC test, decreased from 16.4 ± 0.12 mm to 2.3 ± 0.12 mm, and the "heartburn"symptom disappeared in 100% of cases.Conclusions. In the formation of the “heartburn”symptom in patients with chronicnon-atrophic gastritis, the leading factor is the level of ammonia produced by H. pyloriinfection.
