目的：评估超声内镜在胃癌术前TN分期的正确性,提高超声内镜诊断水平。方法：133例经胃镜及病理证实的胃癌患者于术前进行超声内镜检查和TN分期,并与术后组织病理分期比较。结果：超声内镜对胃癌术前T分期判断的总体准确率为81.20%,其中对T1和T4正确率较高,分别为91.67%和85.0%,而T2和T3的正确率较低,分别为74.29%和70.0%。在T分期中存在着分期过深或过浅的现象,8例分期过深,17例分期过浅,T1和T4正确率较高,而T2和T3正确率稍低。超声内镜胃癌术前分期与术后病理分期呈高度一致性(P<0.01)。 N 分期判断的总体准确率78.95%,淋巴结阳性和阴性的正确率分别为66.10%和89.19%,与术后病理分期差异有统计学意义(P<0.05)。结论：超声内镜能较准确地判断胃癌TN分期,可为医生制订合理的治疗方案提供依据。

Objective:To evaluate the value of endoscopic ultrasonography( EUS) in the preoperative TN staging of gastric cancer,and to improve its diagnostic level. Methods:The preoperative TN staging of gastric cancer diagnosed by pathology in 133 patients were identified by EUS,which was compared with the postoperative histopathological stage. Results:The overall accuracy rate of preoperative T staging of gastric cancer detected by EUS was 81. 20%. The accuracy of T1 and T4 were high,whose were 91. 67% and 85. 0%,the accuracy of T2 and T3 were low,whose were 74. 29% and 70. 0%,respectively. There were too deep or too shallow phenomenon in the T staging,too deep in 8 cases and too shallow in 17 cases were found. The preoperative staging of gastric cancer detected by EUS was highly consistent with the postoperatively pathological staging(P<0. 01). The overall accuracy rate of N staging identified by EUS was 78. 95%,the accuracy rate of positive and negative lymph node were 66. 10% and 89. 19%,respectively,the differences of whose compared with the postoperatively pathological staging were statistically significant ( P < 0. 05 ). Conclusions: Endoscopic ultrasonography can accurately identified the TN staging of gastric cancer, which can provide the basis in formulating the reasonable treatment.
