Endosonography is an imaging method where a high frequency ultrasound probe is inserted blindly or under endoscopic control into a lumen. Examination of the gastrointestinal tract is performed using dedicated echoendoscopes or transendoscopic miniprobes. The gastrointestinal wall, mediastinum, pancreas, bile ducts, retroperitoneum, and other structures surrounding the gastrointestinal tract are target organs for endosonography. A detailed image of pathological processes can thus be obtained. The method can be used both for primary diagnosis of lesions and in follow-up of gastrointestinal diseases. It is accurate in local staging of cancer and in detecting small lesions, which cannot be seen with other imaging modalities. There are some limitations for optimal examination like stenoses or other factors prohibiting a precise position of the ultrasound transducer. The clinical importance of endosonographic examinations must be continuously evaluated on the basis of new technical modalities and changes in therapeutic procedures.
内镜超声检查是一种成像方法，其中高频超声探头被盲目地或在内镜控制下插入到管腔中。使用专用超声内镜或经内镜微型探头对胃肠道进行检查。胃肠道壁、纵隔、胰腺、胆管、腹膜后间隙以及胃肠道周围的其他结构是内镜超声检查的目标器官。因此可以获得病理过程的详细图像。该方法既可以用于病变的初步诊断，也可以用于胃肠道疾病的随访。它在癌症的局部分期和检测其他成像方式无法看到的小病变方面很准确。像狭窄或其他阻碍超声换能器精确定位的因素等，对最佳检查存在一些限制。必须根据新技术模式和治疗程序的变化不断评估内镜超声检查的临床重要性。
