目的 探讨内镜超声（EUS）检查对判断肿瘤侵犯深度及淋巴结转移的效用,期望有助手术治疗。方法 选择20例胃镜诊断的食管癌患者,10例术前行CT检查作T分级,20例行EUS检查并进行T分级,对其中3例淋巴结作EUS引导下细针穿刺细胞学检查。结果10例中CT分级仅4例与手术结果吻合,EUS检查20例中17例与手术结果分期一致,分级误差主要发生在T4期上。3例淋巴结穿刺2例证实为恶性,无并发症发生、结论 EUS对食管癌T分级有较高的敏感性,EUS引导下穿刺可望进一步提高其准确性。
Objective To investigate the effect of endoscopic ultrasonography (EUS) in determining the depth of tumor invasion and lymph node metastasis, expecting to be helpful for surgical treatment. Methods Twenty esophageal cancer patients were diagnosed by gastroscopy. Ten cases were classified as T grade by CT scan, 20 by EUS examination and T grade. Three cases of lymph nodes were treated by EUS guided fine needle aspiration cytology. Results Of the 10 cases, only 4 of the CT grading were consistent with the surgical findings. Among the 20 cases of EUS, 17 were consistent with the surgical findings. The grading error mainly occurred in the T4 phase. 3 cases of lymph node puncture in 2 cases proved to be malignant, no complications occurred, Conclusion EUS on the classification of esophageal cancer T has a higher sensitivity, EUS-guided puncture is expected to further improve its accuracy.
