The article is devoted to investigation of the Helicobacter pylori (HP) infection in 14 patients after resection of the stomach for ulcers of the gastroduodenal zone. Different methods were used for the assessment of the state of the gastric stump and gastroenteric anastomosis in the postoperative period. In most cases different degree of inflammatory alterations of the gastric mucosa were detected. In 2 cases (14.3%) peptic ulcers of the anastomosis developed. Changes to the gastric stump of 11 patients were associated with the HP infection which involved the mucosa of the anastomosed intestine in 8 patients. The data obtained point to possible participation of HP pathogenesis of the alterations detected after the stomach resection. The question of the expediency of a specific antibacterial therapy in the postoperative period and in treatment of certain kinds of postgastroresectional syndromes is raised.

Gastric cancer (GC) is a significant global health challenge, particularly in high-incidence regions like East Asia. Despite improvements in screening and treatment, the progressive nature of precancerous lesions-such as atrophic gastritis, intestinal metaplasia, and dysplasia-necessitates effective prevention strategies. This review evaluates the role of chemoprevention in GC, focusing on agents designed to target these precancerous lesions.

Ubiquitinylation of proteins regulates manifold processes and is reversed by deubiquitinylating enzymes (DUBs), which are therefore implicated in a plethora of cellular processes. DUBs are frequently upregulated in many diseases, while in a few cases downregulation of DUBs is associated with disease progression. This review focuses on the involvement of DUBs in the development and progression of gastrointestinal diseases with a particular emphasis on hepatic steatosis and hepatocellular, cholangio-, esophageal, gastric, colorectal, and pancreatic ductal carcinomas.
