摘要：

目的 评估超声内镜（EUS）在残胃癌TNM 分期中的准确性。方法 北京大学临床肿瘤学院从2001 年10月至2009 年3 月对连续的21 例病理证实的残胃癌病人给予超声内镜检查，行TNM 分期。所有病人行手术治疗，对照术后病理。结果 评价超声内镜诊断结果结果经超声内镜检查，21 例残胃癌中T2 为3 例，T3 为9 例，T4 为9例；N0 为3 例，N1 为6 例，N2 为4 例，N3 为10 例, 其中手术标本病理分期T2 为3 例T3 为13 例，T4 为5 例，N0 为3例，N1 为4 例，N2 为6 例，N3 为8 例。超声内镜在残胃癌T，N 分期中的诊断准确率分别为81.0% 和76.2%。结论 超声内镜是残胃癌临床分期的一种准确、无创的检测手段。因观察范围所限、淋巴结检测应结合CT 等方法完善分期。

Abstract:

Role of endoscopic ultrasound in the staging of gastric stump carcinoma WU Qi*，LI Zi-yu，BU Zhao-de,et al. * Endoscopy Center，Institute of Clinical Oncology, Peking University School of Oncology, Beijing100142, China Corresponding author：ZHANG Ji-chang, E-mail：drzhangjichang@sina.com Abstract Objective To investigate the accuracity of endoscopic ultrasound (EUS) for staging the gastric stump carcinoma (GSC). Methods Twenty-one consecutive patients with pathological proved GSC were checked with endoscopic ultrasound between October 2001 and March 2009 at Peking University School of Oncology. All patients subsequently underwent remnant total gastric resection with lymph node dissection. The pathological staging with EUS staging was compared. Results Overall T2,T3,T4,N0,N1,N2,and N3 of EUS staging for GSC in the group were3,9,9,3,6,6 and 6 cases, respectively. On the contrast，T2,T3,T4,N0,N1,N2, and N3 of pathological staging in the group were3,13,5,3，4,4 and 10 cases, respectively. Diagnostic accuracy of EUS for GSC TN stage in the group were 81.0% and 76.2%. Conclusion EUS is a non-invasive technique with high accuracy for TN staging in the GSC patients. However, due to the low specificity with metastasis lymph nodes, it is suggested to ally with CT .
