Abstract
The aim: To determine of the factors influencing the formation of "kissing" duodenal bulb ulcer in patients with chronic non-atrophic gastritis. Materials and methods: The data of a comprehensive examination of 34 patients with chronic non-atrophic gastritis were analyzed, in which the examination revealed "kissing" ulcers of the duodenal bulb (primary group), and 37 patients with chronic non-atrophic gastritis, in which single ulcers were detected in the bulb (control group). Comprehensive examination included: step-by-step intragastric pH-metry, esophagogastroduodenoscopy, helicobacter infection test (НР) (helicobacter urease test and microscopic examination of stained smears), histological investigations of the gastric stump mucous, material for which was taken during endoscopy from 4 topographical zones: from the middle third of the gastric antrum and body of stomach on the big and small curvature. Results: In the course of the examination, the presence of chronic non-atrophic gastritis in 100% of cases was confirmed with a different degree of activity of the inflammatory process on the gastric mucosa, as well as the presence of Helicobacter pylori infection with a high degree of colonization of the gastric mucosa in the absence of a significant difference (p> 0.05) in the stomach zones. It was found that the main difference that can be traced in 100% of cases is the difference in the anatomical structure of the bulb of the duodenum, namely, the shape: in the control group, the shape and lumen of the duodenal bulb are round, while in the patients of the main group the bulb the duodenum, starting from the pylorus, is stretched toward the large and small curvature, which gives the lumen bulb its oval shape. Conclusions: "Kissing" ulcers of the duodenal bulb are formed in patients with chronic non-atrophic gastritis only if the patients have a peculiar anatomical structure of the bulb, in which the lumen has an oval shape.
