超声内镜对食管癌和贲门癌切除可能性的术前评估

目的探讨超声内镜在食管癌和贲门癌的临床诊断上的应用价值。方法自1996年3月至1997年8月，应用超声内镜检查33例食管癌和28例贲门癌，了解癌肿的影像特征，浸润深度及癌旁淋巴结情况。结果超声内镜显示肿瘤影像特征为不规则的低回声肿块伴部分或全部管壁结构的破坏；对肿瘤浸润深度诊断总符合率：食管癌为81．8％，贲门癌为75％：对癌旁淋巴结的发现率：食管癌为88．9％，贲门癌为92％：超声内镜发现癌旁肿大淋巴结癌转移率：食管癌为75％，贲门癌为91.39％。结论超声内镜对食管癌、贲门癌术前临床治疗方法的选择、手术方式的确定和预后的评估具有重要的参考价值。

Application of endoscopic ultrasonography in assessment of the possibility of resection of esophageal cancer and cardiac cancer

Objective To elucidate the value ofendoscopic ultrasonography (EUS) in the clinical diagnosis of esophageal cancer andcardiac cancer. Methods 33 patients with esophageal cancer and 28 patients with cardiac cancer were examined by EUS to analysethe image features of tUmor, the depth of the tUmor invasion and the enlarged lymph nodes around tUmor. Results Both thecarcinomas were imaged as an irregijlar hypoechoic mass with partial or total destruction of normal wall structUre. The coineidencerate of the depth ofcarcinoma invasion diagnosed by EUS with the pathological findings was sl .8% for esophageal cancer and 92%for cardiac cancer. PFhe finding rates of the enlarged paracancarous lymph node of both the cancers were 88.9% and 92% respectively.The finding rate of the metastaic lymph node by EUS was 75% for esophageal cancer and 91.3% for cardiac cancer. ConclusionEUS is helpful to the selection of therapeutic methods, determination of surgical procedure and evaluation of the prognosis for thosepatients with esophageal cancer and cardiac cancer.
