应用超声内镜（EUS）对23例食管癌患者进行T分期诊断。结果表明：EUS诊断癌的浸润深度与病理诊断的总符合率为83．75％；EUS诊断淋巴结转移与病理诊断的符合率为80％。EUS对食管癌手术治疗的方式有重要意义，将成为术前重要的检查手段。
Endoscopic ultrasonography (EUS) was used to diagnose T-stages in 23 patients with esophageal cancer. The results showed that the overall coincidence rate of EUS diagnosis of cancer invasion depth and pathological diagnosis was 83.75%; the coincidence rate of EUS diagnosis of lymph node metastasis and pathological diagnosis was 80%. EUS is important for the surgical treatment of esophageal cancer and will be an important preoperative examination.
