钡餐造影和CT在食管癌诊断治疗中的应用价值

目的：综合评价CT和钡餐造影在食管癌诊断和治疗中的应用价值。方法：160例食管癌患者均行CT和钡餐造影，其中51例行放射治疗CT定位，对其影像表现进行对照分析。结果：⑴钡外造影能准确定位，显示病变实际长度，确定病理类型。⑵CT外侵检出率为80.6%，钡餐造影为31.8%，以中上胸段食管癌外侵率高，主要侵犯部位为气管、支气管和主动脉。⑶淋巴结检出率CT为37.5%，钡餐造影为0。⑷CT发现有远处转移6例。结论：钡餐造影是食管癌诊断的首选检查手段，同时患者在术前或放射治疗前进行CT检查，为确定临床分期、估计预后、选择合适的治疗方法、设计最佳的放射治疗计划以达到最理想的治疗效果提供重要的依据和参考价值，是钡餐造影重要的补充手段。

Evaluation of the clinical value of CT and esophageal barium meal in diagnosis and therapy for esophageal cancer

Objective: To evaluate comprehensively the clinical value of CT and esophageal barium meal in esophageal carcinoma. Methods: CT imaging and esophageal barium meal were performed in 160 cases. Fifty one cases out of the 160 cases underwent CT location and their images were analyzed comparatively. Results: (1) The esophageal barium meal was superior in locating accurately,appearing actual length and determining pathologic type. (2) The rate of extra-esophageal invasion were 80.6% and 31.8% in CT and esophagography respectively; the upper and middle thoracic segment of esophagus were highest in all cases. Major locations of invasion for CT were trachea,bronchus and aorta. (3) The rate of lymgh nodes metastasis were 37.5% in CT, zero in X-ray barium meal.(4)Metastasis of other organs were found by CT in 6 cases. Conculsion: X-ray barium meal examination is the first means to diagnose esophageal cancer. Undergoing CT examination before operation or radiotherapy can provide improtant basis and reference value for determining clinical stage, estimating prognosis, choosing rational therapeutic methods and designing the best radiotherapy plans in order to attain the most ideal therapeutic effect. So it is an additional method for esophageal barium meal.
