Endoscopic sonography combines direct visualization of the luminal surface of the gut with sonographic examination of the gut wall and surrounding structures. Lesions arising from different layers of the wall can be identified, staged, and in some cases characterized. Endoscopic sonography is complementary to endoscopy, barium studies, transabdominal sonography, and CT examination of gastrointestinal lesions. A thorough examination with endoscopic sonography may determine the layer of origin, size, echogenicity, and extent of gastric lesions and allows differentiation of lesions arising in the stomach from lesions arising outside the stomach. The purpose of this essay is to illustrate the findings from endoscopic sonography of a variety of benign and malignant lesions of the stomach.
内镜超声检查将肠道腔内表面的直接可视化与肠壁及周围结构的超声检查相结合。可以识别、分期并在某些情况下对源自肠壁不同层次的病变进行特征描述。内镜超声检查是对内镜检查、钡剂造影、经腹超声检查及胃肠道病变CT检查的补充。通过内镜超声检查进行全面评估，可确定胃部病变的起源层次、大小、回声性及范围，并能区分胃内病变与胃外病变。本文旨在阐述各种胃部良恶性病变的内镜超声检查结果。
