目的探讨超声内镜检查( EUS) 在胃癌术前分期中的临床应用价值. 方法回顾性分析解放军第二五二医院消化内镜中心自2008 年1 月至2013 年12 月经胃镜活检证实为胃癌的210例患者,术前行超声内镜检查,并与术后病理结果对照.结果 EUS对胃癌T分期的准确率分别为Tl 95.8%(46/48)、T2 81.3%(48/59)、T3 83.9%(68/81)和T4 77.2%(17/22). EUS对胃癌无( N0 )、有( N+) 淋巴结转移判断的准确率较高,分别为N0 85 .5%( 65/76 )和N+88 .8%( 119/134 );EUS对于较大淋巴结(直径>0.5 cm) 的判断较为准确,而对于较小的淋巴结 (直径<0.5 cm,尤其<0.3 cm) 则难以准确判定其是否为转移灶.结论 EUS对胃癌术前T分期具有较高的临床应用价值.

Objective To explore the clinical value of endoscopic ultrasonography ( EUS ) in preoperative staging of gastric cancer .Methods EUS was performed in 210 patients with gastric cancer examinized in Department of Gastroenterology , No.252 Hospital of PLA from January 2008 to December 2013. proved by biopsy before operation:the results were compared with postoperative pathologic findings .Results The accuracy of EUS in determining the T stage of gastric cancer was T 1 95.8%,T2 81.3%,T3 83.9%,and T4 77.2%,respectively.The accuracy of EUS in determining lymph node metastasis (LNM) was 85.5%(LNM negative) and 88.8% (LNM positive),respectively.It was easy for EUS to determine the LNM status of relatively large lymph node whose diameter was larger than 0.5 cm, but difficult to the small lymph node with the diameter smaller than 0.5 cm (especially <0.3 cm).Conclusion The clinical value of EUS in the preoperative T staging for patients with gastric cancer is relatively high .
