Clinical characteristics of patients with early gastric prematurity cancer and analysis of complications by endoscopic resection

Analysis of the clinical characteristics indicated that early gastric cancer is more prevalent in males with a history of hypertension, with lesions most commonly occurring in the antral region of the stomach. The pathological types are often high-grade intraepithelial neoplasia and well-differentiated adenocarcinoma, with over 85% of patients having comorbid intestinal metaplasia and atrophy. Despite endoscopic resection, a positive margin rate persisted, indicating a probability of residual cancer at the margins. Postoperative complications, such as gastrointestinal obstruction, incisional infection, gastric perforation, and gastric bleeding can occur and require timely symptomatic treatment.
