We investigated the usefulness of endoscopic ultrasonography (EUS) of lymph nodes surrounding the upper GI tract and tried the enhanced EUS by the method of the oral administration of '10% oil-in-water-type emulsion.' The results were as follows: The ultrasonographic visualization rate of lymph nodes surrounding the esophagus was 33.7% in total; however, it was 43.4% for those greater than 5 mm and 58.7% for those greater than 10 mm. The frequency of lymph node metastasis of esophageal cancer was 48.1% for those larger than 10mm with a round shape and 14.3% for the same size with an ellipsoid shape; for those less than 10mm, it was also low. Lymph nodes surrounding the esophagus and the stomach were enhanced by administration of 10% oil-in-water-type emulsion. The visualization rate of lymph nodes can be increased by using this new method. Endoscopic ultrasonography is very useful for the detection of swelling lymph nodes surrounding the upper GI tract before the operation.
我们研究了上消化道周围淋巴结的内镜超声检查（EUS）的实用性，并尝试通过口服“10%水包油型乳剂”的方法进行增强型EUS。结果如下：食管周围淋巴结的超声可视化率总体为33.7%；然而，直径大于5mm的淋巴结可视化率为43.4%，直径大于10mm的淋巴结可视化率为58.7%。食管癌淋巴结转移频率在直径大于10mm且呈圆形的淋巴结中为48.1%，在相同大小呈椭圆形的淋巴结中为14.3%；对于直径小于10mm的淋巴结，转移频率也较低。口服10%水包油型乳剂可增强食管和胃周围的淋巴结。使用这种新方法可提高淋巴结的可视化率。内镜超声检查对于术前检测上消化道周围肿大的淋巴结非常有用。
