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,Nl,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.
