腔内超声在食管平滑肌瘤诊断及鉴别诊断中的应用

目的：研究食管腔内超声在食管平滑肌瘤诊断及鉴别诊断中的应用价值。方法：从1996年9月到2000年8月,对23例食管粘膜下肿瘤和11例食管外压性疾病患进行了腔内超声检查。其中32例还进行了CT扫描检查,除3例血管外压性疾病外,其余全部均接受手术治疗。结果：23例食管粘膜下肿瘤患者中,腔内超声对食管平滑肌瘤诊断的准确率为95．7％（22／23）,而CT仅为42．9％（9／21）,两者差异有显著性意义（χ^2=14.69,P=0.0196),11例食管外压性疾病中,腔内超声均能准确地将其与食管平滑肌瘤区分开来。结论：在食管平滑肌瘤的诊断及鉴别诊断中,腔内超声是一项很可靠的检查手段。

Transesophageal intraluminal ultrasonography in diagnosis and differential diagnosis of esophageal leiomyoma

OBJECTIVE: To evaluate the diagnostic and differential diagnostic values of transesophageal echo probe (TEEP) or endoscopic ultrasonography (EUS) in the diagnosis and differential diagnosis of esophageal leiomyoma. METHODS: Between September 1996 and August 2000, TEEP or EUS was used among 23 patients with esophageal submucosal tumor and 11 patients with esophagus constricted from outside, among which 32 cases underwent CT too. All the patients except and 3 with constriction by aorta underwent surgical treatment. RESULTS: (1) The accuracy rate of diagnosis of esophageal leiomyoma by TEEP or EUS was 95.7% (22/23) in comparison with that by CT of only 42.9% (9/21, chi(2) = 14.69, P = 0.0196). (2) In the 11 patients with esophagi constricted by masses beyond or around esophagus, TEEP or EUS definitely differentiated the damage beyond or around esophagus from esophageal leiomyoma. CONCLUSION: Transesophageal intraluminal ultrasonography (TEEP and EUS) is a reliable method for the preoperative diagnosis and differential diagnosis of esophageal leiomyoma and is more accurate than CT.
