除菌治疗对胃窦早癌内镜下表现的影响:1例报道

The effect of sterilization treatment on endoscopic manifestations of gastric antral early cancer: one case report

幽门螺杆菌活动性感染状态下,胃黏膜较重的炎症背景对早期胃癌病灶的形态、色泽、范围等特点的内镜下识别造成干扰,也同样影响放大内镜下对病变微结构和微血管异型性的辨识,增加病变性质诊断的难度,甚至造成漏诊。对于除菌前发现的可疑病灶,成功的除菌治疗明显减轻黏膜的炎症背景,增加内镜下判别病变色调、范围、形态以及表面微结构、微血管的正确度,提高早期胃癌的诊断正确率。本文将报道1例胃窦早癌在除菌治疗前后的内镜下特点变化。

Under the condition of H.pylori active infection,the background of heavy inflammation of the gastric mucosa interferes with the endoscopic identification of the morphology,color and scope of the lesions in early gastric cancer,and also affects the identification of the lesion microstructure and microvascular atypia under amplification endoscopy,which increases the difficulty in the diagnosis of the lesion nature and even leads to missed diagnosis.For suspicious lesions detected before sterilization,successful sterilization treatment can significantly reduce the background of mucosal inflammation,increase the accuracy of discriminating lesion color,range,shape,surface microstructure and microvessels under endoscopy,and improve the diagnostic accuracy of early gastric cancer.This paper reported the endoscopic characteristics of one case of early gastric antral early cancer before and after sterilization treatment.
