目的:总结90例胃黏膜上皮内瘤变的内镜及病理特征。方法:收集2007至2012年胃黏膜上皮内瘤变90例患者资料,重点就内镜形态、病理特征进行回顾性分析。结果:胃黏膜上皮内瘤变大部分位于胃窦、胃角,占85.55%,形态可表现为单发溃疡、单发糜烂,多发溃疡、多发糜烂、息肉等,高级别上皮内瘤变癌变率高,达90.90%。结论:胃黏膜上皮内瘤变是胃癌前病变,必须结合内镜活检、病理及定期随访,才能作出早期、准确诊断,必要时须重复二次甚至多次内镜病理检查才能确诊。
Objective: To summarize the endoscopic and pathological features of 90 cases of gastric intraepithelial neoplasia. Methods: The data of 90 patients with gastric intraepithelial neoplasia from 2007 to 2012 were collected. The focus was on retrospective analysis of the endoscopic features and pathological features. Results: The majority of gastric intraepithelial neoplasia located in the antrum and stomach corner accounted for 85.55%.

Conclusions: Gastric mucosal intraepithelial neoplasia is a precancerous lesion of the stomach.
