作者对46例食管癌患者作了内窥镜超声和CT检查,就二者对食管癌术前分期的价值作了比较。46例患者均手术,44例有纵隔和腹腔淋巴结的病理检查。CT和内窥镜超声检查结果与外科、病理所见作对照。46例患者共发现51个肿瘤病灶,超声检查对37个(73%)肿瘤的食管各层浸润深度判断正确。但46例病人中有23例(50%)因病变处食管狭 The authors performed endoscopic ultrasonography and CT scans on 46 patients with esophageal cancer and compared the value of the two before the staging of esophageal cancer. All 46 patients were operated and 44 patients had pathological examinations of mediastinal and celiac lymph nodes. The results of CT and endoscopic ultrasonography were compared with surgical and pathological findings. A total of 51 tumor lesions were found in 46 patients. Ultrasonography correctly diagnosed the depth of invasion of 37 esophageal layers in 37 (73%) tumors. However, 23 (50%) of the 46 patients had esophageal strictures due to lesions.
