螺旋CT多层平面重建在食管癌术前分期中的应用价值

Application value of spiral computed tomography in the preoperative staging of esophageal cancer

目的评估螺旋CT多层平面重建(MPR)在食管癌术前分期中的应用价值。方法选择86例食管癌患者,回顾性分析螺旋CT影像学资料,并与病理资料进行对照,分析螺旋CT对食管癌术前分期的判断准确性,观察项目包括食管癌病变部位、肿瘤对周围组织、器官的侵犯以及Moss改良分期。结果螺旋CT能够显示病灶的位置、范围,管壁及管腔的变化以及周围脂肪的异常改变。本组螺旋CT的食管癌术前分期诊断准确性为80.2%(69/86),对食管癌术前外侵的诊断准确性为87.2%(75/86),对食管癌术前淋巴结转移的诊断准确性为83.7%(72/86)。结论螺旋CT在食管癌术前分期中具有重要的临床应用价值,能够判断病灶的位置、范围、管壁及管腔的变化以及周围脂肪的异常改变等,为临床诊治提供可靠的参考依据。

Objective To evaluate the application value of spiral computed tomography（ CT） in the preoperative staging of esophageal cancer. Methods A total of 86 cases of esophageal cancer patients were selected,and their spiral CT imaging data were analyzedretrospectively,and compared with pathologic analyzes. The esophageal lesions,tissue surrounding the tumor,as well as violations of Moss improved organ staging were observed. Results Spiral CT showed changes in the lesion location,extent,and the wall surrounding the lumen and abnormal fat. The diagnostic accuracy of preoperative staging in 86 cases of this group was 80. 2%（ 69 /86）; The accurate rate judged whether there was invasion out of esophagus by cancer preoperation was 87. 2%（ 75 /86）; The diagnostic accuracy of lymph node metastasis was 83. 7%（ 72 /86）. Conclusions Spiral CT has important clinical value in the preoperative staging of esophageal cancer,can determine the location of the lesion,range,wall and lumen changes and abnormal changes in surrounding fat,and it provides reliable reference for clinical diagnosis and treatment.
