Value of Position of Buttocks Higher than Head in CT Scan in Preoperative Staging of Cardiac Carcinoma

目的 探讨臀高头低位CT扫描对贲门癌术前分期的应用价值。方法 利用自制可调式角度板对 80例贲门癌患者行臀高头低位CT扫描进行术前分期。结果 80例中CT术前临床分期正确率为 82 .5 %。手术的 67例中T、N、M分期正确率分别为 77.6%、78.1%和 91% ;肿瘤对周围脏器侵犯的敏感性、特异性、准确性分别为 :76.5 %、96%、91% ,手术切除率 95 .5 %。结论 臀高头低位CT扫描对贲门癌术前分期有重要价值 ,可提高手术切除率。

Objective To study the value of position of buttocks higher than head in CT scan in preoperative staging of cardiac carcinoma. Methods There were 80 cases with cardiac carcinoma proved by both double contrast barium examination and endoscopy examination.CT scans were performed in all cases at the position of buttocks higher than head by adjustable angle boards.Sixty seven cases were correlated with operative and pathologic findings. Results The total accuracy of CT scan of 80 cases in determining clinical staging was 82.5%(66/80).The accuracy of 67 cases in determining T, N, M staging was 77.6%, 78.1% and 91%. The sensitivity, specificity and accuracy in determining regional invasion were 76.5%, 96%, 91%respectively. The resectability was 95.5%. Conclusion The position of buttocks higher than head CT scan in preoperative staging of cardiac carcinoma is of great value and can improve the resectability.
