目的:探讨高原地区老年胃溃疡患者胃镜下特点,以指导临床诊治。方法:从胃溃疡的部位、大小、并发症及病理学分析我院100例老年胃溃疡患者的胃镜资料及镜下特点,并与同期青年胃溃疡患者的胃镜资料进行比较。结果:高原地区老年胃溃疡患者与青年胃溃疡患者胃镜结果比较,癌前病变及并发症发生率较高,溃疡发生部位以胃体部为主,溃疡病灶面积较大,差异均具有统计学意义(P<0.01)。结论:高原地区老年人胃溃疡病变程度严重,癌变发生率高,后果严重,应引起临床重视。 Objective: To investigate the characteristics of gastroscopy in the elderly patients with gastric ulcer in the plateau to guide clinical diagnosis and treatment. Methods: Gastroscopy data and microscopic features of 100 elderly patients with gastric ulcer in our hospital were analyzed according to the location, size, complications and pathology of gastric ulcer. Gastroscopy data of patients with gastric ulcer in the same period were also compared. Results: Compared with gastroscopy, the incidence of precancerous lesions and complications was higher in patients with senile gastric ulcer and young patients with gastric ulcer in the plateau. The main part of the ulcer occurred in the gastric body and the area of ​​the ulcer was larger, the differences were statistically significant (P <0.01). Conclusion: The prevalence of gastric ulcer in the elderly is high in the plateau, with high incidence of carcinogenesis and serious consequences, which should be paid more attention to.
