【摘要 】目的提高上消化道粘膜下肿瘤的确诊率。方法对117例疑为上消化道粘膜下肿瘤的患者进行内镜超声检查(EUS)。结果发现外压性改变25例(其中脾脏19例，主动脉弓4例，肝左叶、胰尾囊肿各1例)；粘膜下肿瘤92例，包括肌源性肿瘤63例(食管34例、胃29例)，胃异位胰腺9例，食管囊肿8例，胃底静脉瘤3例，胃淋巴瘤3例，胃脂肪瘤2例，巨大胃粘膜肥厚症2例，食管脂肪瘤、食管静脉瘤各1例。经病理证实37例。结论EUS能清楚地显示消化道管壁各层，准确判断肿瘤浸润层次，用于指导粘膜下肿瘤的诊断；但是对一些肿瘤，尤其是肌源性肿瘤良恶性的鉴别诊断则有一定的困难。

【 Abstract 】 Objective The accuracy of diagnosing submucosal tumors (SMTs) in upper gastrointestinal (GI) tract was to be improved. Methods Endoscopic ultrasonography (EUS) had been conducted in 117 patients with suspected SMT. Results 25 protuberances from outside organ (spleen, n=19; aorta, n=4; left hepatic lobe, n=1 and cyst of pancreatic tail, n=1) and 92 SMTs were detected by EUS including 63 myogenic ones (esophageal, n=34; gastric, n=29), 9 etopic pancreases in stomach, 8 esophgeal cysts, 3 varices in gastric fundus, 3 gastric lymphomas, 2 gastric lipomas, 2 Menetrier ’ s disorders, 1 esophageal lipoma and varix each. Of which 37 were identified by pathology. Conclusion Different layers of GI wall with tumor invasion, if any, can be distinguished clearly by EUS, leading to definite diagnosis of SMT, but it is difficult to differentiate malignant myogenic tumor from the benign.
