目的 评价多平面经食管超声心动图 (MTEE)在食管癌术前诊断和分期中的作用。方法 对 2 9例食管癌患者进行了X线钡餐、纤维胃镜和MTEE检查 ,所有患者均经手术治疗并将上述检查结果与术后病理结果作对照。结果 MTEE判断食管癌的T分期与病理结果一致性较好 ,Kappa值为 0 .6 3 ,MTEET分期准确率为 81.5 %。MTEE测量食管癌的长度和最大厚度与病理结果无显著性差异 (P >0 .0 5 ) ,而纤维胃镜测量肿瘤的长度与病理结果有显著性差异 (P <0 .0 5 )。MTEE对食管周围淋巴结总显示率为 5 3 .1% ,转移淋巴结显示率为 6 9.2 %。结论 MTEE对食管癌术前的诊断和分期有较高的准确性 ,其辅助诊断作用在临床上有一定实用价值
Objective To evaluate the role of multiplanar transesophageal echocardiography (MTEE) in preoperative diagnosis and staging of esophageal carcinoma. Methods Twenty-nine patients with esophageal cancer underwent X-ray barium meal, fiberoptic gastroscopy and MTEE examination. All patients were treated by surgery and the above results were compared with postoperative pathological results. Results MTEE showed a good agreement between T staging and pathological findings in esophageal cancer, Kappa value was 0.63, and MTEET staging accuracy was 81.5%. The length and maximum thickness of esophageal cancer measured by MTEE were not significantly different from pathological results (P > 0.05), but the length of the tumor measured by fiberoptic gastroscopy was significantly different from the pathological results (P < 0.05). The total display rate of MTEE in the peri-esophageal lymph nodes was 53.1%, and the metastatic lymph node display rate was 69.2%. Conclusion MTEE has high accuracy in the preoperative diagnosis and staging of esophageal carcinoma, and its auxiliary diagnosis has a certain clinical value.
