In diagnosing superficial esophageal carcinoma, it is necessary to differentiate mucosal carcinoma from submucosal carcinoma because mucosal carcinoma has a good prognosis and local treatment is likely to be successful. We evaluated an ultrasound probe and endoscopic ultrasonography (EUS) in the staging of superficial esophageal carcinoma.
From October 1992 to September 1994, 22 patients with 25 lesions (7 mucosal carcinomas, 18 submucosal carcinomas) were examined preoperatively with both the probe and EUS. The ultrasound findings were compared with histologic findings in all cases.
The accuracy rates of the depth of invasion by the ultrasound probe were 86% (6 to 7) for mucosal carcinoma and 94% (17 to 18) for submucosal carcinoma, total 92% (23 to 25); by EUS 71% (5 to 7) for mucosal carcinoma and 78% (14 to 18) for submucosal carcinoma, total 76% (19 to 25). In the evaluation of lymph node metastasis, the overall accuracy was 56% by the ultrasound probe (sensitivity 25% and specificity 80%) and 67% by EUS (sensitivity 50% and specificity 80%).
The ultrasound probe was more convenient to use and more accurate than EUS in the evaluation of the depth of invasion of superficial esophageal carcinoma.
在诊断浅表性食管癌时，区分黏膜癌和黏膜下癌很有必要，因为黏膜癌预后良好，局部治疗可能会成功。我们评估了一种超声探头及内镜超声检查（EUS）在浅表性食管癌分期中的应用。
1992年10月至1994年9月，对22例患者的25个病灶（7例黏膜癌，18例黏膜下癌）术前使用该探头及EUS进行检查。将所有病例的超声检查结果与组织学检查结果进行比较。
超声探头对黏膜癌浸润深度的准确率为86%（6/7），对黏膜下癌为94%（17/18），总体为92%（23/25）；EUS对黏膜癌浸润深度的准确率为71%（5/7），对黏膜下癌为78%（14/18），总体为76%（19/25）。在评估淋巴结转移方面，超声探头的总体准确率为56%（敏感性25%，特异性80%），EUS为67%（敏感性50%，特异性80%）。
在评估浅表性食管癌浸润深度方面，超声探头比EUS使用更方便且更准确。
