Aim. This study aimed to evaluate the biochemical characteristics of gastric juice in cases incompetence of the physiological cardia (IPC) at the gastroesophageal junction.
Methods. Gastric juice samples were collected from 42 patients diagnosed with hiatal hernia (HH) at the State Institution "Institute of Gastroenterology of the National Academy of Medical Sciences of Ukraine". Patients were classified into type I (sliding) HH (n=26) and type II (paraesophageal) HH (n=16), with a control group of healthy volunteers (n=9).
Results. Analysis included pH, pepsin concentration, bile acids, total calcium and stable metabolites of nitric oxide (NOx). In type I HH, gastric juice showed increased pH (3.73±0.49) and elevated pepsin concentration (1.33±0.22 mg/ml) compared to controls (p<0.01 and P<0.05 respectively), indicating hypoacidity and hyperfunction of chief cells. Type II HH exhibited pH levels (2.34±0.72) similar to controls and no significant difference in pepsin concentration. NOx levels in type I HH were lower (P<0.05) compared to controls, suggesting reduced NOergic system activity. Calcium concentration in gastric juice did not significantly differ between groups.
Conclusions. These findings suggest that type I HH is associated with disturbances in gastric secretion regulation, possibly unrelated to duodenogastric reflux. Further investigation is warranted to elucidate the underlying pathophysiological mechanisms.
Key words: incompetence of the physiological cardia, gastric juice, hiatal hernia.
