Detect The Most Important Changes That Occur in The Stomach Tissue of Patients Infected With H. Pylori

The current study aimed to detect the most important changes that occur in the stomach tissue of patients infected with H. pylori. Samples were collected from the Endoscope Unit for the period from 12/14/2022 to 1/30/2024 at Azadi Teaching Hospital and Al-Watan Al-Ahli Hospital in Kirkuk Governorate, from both sexes for the age group (14-57) years. Stool samples were taken from the same patients those undergoing laparoscopy for the purpose of investigating the presence of Helicobacter pylori. Tissue biopsy samples were taken by the gastroenterologist using laparoscopic forceps, and (88) samples were obtained from these patients, with two tissue biopsies from each patient. The histological results of people infected with Helicobacter pylori bacteria showed many histological changes, including infiltration of inflammatory cells, which was accompanied by multiple tissue necrosis, and damage to some gastric glands as a result of degeneration of glandular epithelial cells with thickening of the basal membrane, in addition to necrosis and damage to most of the gastric glands. Narrowing of the lumen of some glands, sometimes their complete atrophy, metaplasia of the epithelial cells of the gastric glands and the epithelial tissue lining the antral area, and cell shedding occur. It is concluded from the current study that H. pylori has led to many tissue lesions in the stomach of patients, the most important of which is stomach ulceration.
