超声在食管癌及淋巴结转移诊断中的价值

Value of Ultrasonography in D iagnosis of Esophageal Carcinoma

目的:探讨经体表超声在食管癌及淋巴结转移诊断中的价值。方法:应用经体表超声检查150例食管癌患者,另外以90例正常人作为对照,观察食管壁厚度、回声特点,并记录淋巴结及肝脏的转移情况。结果:经体表超声对颈段、胸段、腹段食管癌的诊断符合率分别为90.7%、61.8%、88.1%,食管癌的管壁较对照组增厚(P<0.05),厚度大于5mm,经体表超声显示颈段、胸段、腹段食管癌食管周旁淋巴结转移的诊断符合率分别为80.9%、45.7%、86.2%,显示颈部锁骨上窝及腹腔淋巴结转移的诊断符合率分别为98.7%及100%。结论:经体表超声对食管癌及淋巴结转移情况具有重要的诊断价值。

Objective：To assess the value of transabdominal ultrasonography in the diagnosisof esophageal carcinoma. Methods： 150 patients with esophageal carcinoma and 90 healthy subjects as controls were examined by transabdominal ul- trasonography. The thickness and echo of the esophageal wall was observed. Results ：The coincidence rate of transabdominal uhrasonography for diagnosing cervical segment, thoracic segment and pars abdominalis esophageal carcinoma was 90.7% , 61.8% and 88.1%. The esophageal wall was significantly thicker in patients with esophageal carcinoma than that in con- trois （ P 〈 0.05 ）. The accuracy in detecting lymph nodes metastasis around cervical sebnnent, ,thoracic segment and pars ab- dominalis esophageal carcinoma was 80.9% ,45.7% and 86.2%. The accuracy in detecting lymph nodes metastasis of su- praelavicular fossa and abdominal cavity was 98.7% , 100%. Conelusion：Transabdominal ultrasonography possesses a key value in the diagnosis of esophageal carcinoma.
