线阵式彩色内镜超声对食管癌的分级诊断

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。

Diagnostic significant of curved linear array endoscopic ultrasonography in diagnosing easophageal carcinoma

Objective To study the influence of T staging by EUS on choicing treatment and its effect on evaluating the tumor invasive depth and lymph node metastasis of esophageal carcinoma. Methods From March 2000 to May 2001, 20 patients with esophageal carcinoma underwent preoper-ative EUS,and in 10 of them CT was conducted preoperatively. After September 2001 EUS-guided FNA was performed in 3 patients on nonperitumoral lymph nodes greater than 5 mm in width. Final diagnosis was based on surgical results or EUS-guided FNA cytological examination. Results The results of post operative staging were compatible with those of EUS and CT in 17/20 and 4/10 cases respectively. Two of 3 patients were positive for EUS-guided FNA malignant cytology. There was no complications in FNA. Conclusions EUS is an accurate way to evaluate esophageal cacinoma T stage and EUS-FNA is more accurate than EUS alone for preoperative staging.
