放射性胃、十二指肠黏膜损伤内镜下分级与病理变化相关性研究摘要:
目的:探讨放射性胃、十二指肠黏膜损伤内镜下分级与病理变化相关性。
方法:选取2015年1月至2018年12月于某医院接受放射治疗且内镜检查显示胃、十二指肠黏膜损伤患者60例,按照内镜下分级标准分为轻度、中度、重度组;对患者进行病理学分析,比较各组黏膜受损程度与病理变化之间的关系。
结果:内镜分级轻度、中度、重度组分别为12例、23例、25例,其中男性34例,女性26例,平均年龄59.5岁。病理分析结果显示,轻度组病变主要为黏膜水肿和上皮细胞变化,中度组出现肉芽组织形成和炎性浸润,重度组出现溃疡、根性创面以及肌层受损等。
结论:放射性胃、十二指肠黏膜损伤内镜下分级与病理变化有一定相关性,内镜下分级结果可以较好地反映黏膜受损的程度。不同程度的黏膜受损病理学变化不同,相关机制尚待深入探讨。
