Endoscopic ultrasonography (EUS) is the latest procedure in the field of gastroenterology and is highly evaulating now because of its unique diagnosing method. For the example, the intra- and extra-mural informations of the GI tract can be known through this technique. In this paper, we reported on the usefulness of EUS in the diagnosis of the depth invasion of the colonic cancer and introduced the new and exclusive instrument for the colon. Namely, we could obtain the accurate diagnosis in 18 out of 20 cases with the rectal or the sigmoid colon cancer. One of causes of misdiagnosis in 2 cases of early cancer was due to the ghost echo. Another cause was the cancer cells infiltration to the deeper tissue which could be recognized only by a microscope. Then, we tried to examine the entire colon in 2 cases using the new instrument and succeeded to insert the endoscope to the cecum in a short time. In conclusion, we were convinced that EUS would develop the new aspect in the diagnosis of the colonic diseases including cancer.
内镜超声检查（EUS）是胃肠病学领域的最新技术，因其独特的诊断方法目前受到高度评价。例如，通过该技术可以了解胃肠道壁内和壁外的信息。在本文中，我们报告了EUS在诊断结肠癌深度浸润方面的实用性，并介绍了一种新型的专用结肠检查仪器。也就是说，我们对20例直肠癌或乙状结肠癌患者中的18例做出了准确诊断。2例早期癌症误诊的原因之一是伪像回声。另一个原因是癌细胞浸润到更深层组织，这只能通过显微镜识别。然后，我们尝试使用新仪器对2例患者进行全结肠检查，并成功在短时间内将内镜插入盲肠。总之，我们确信EUS将在包括癌症在内的结肠疾病诊断中开拓新的局面。
