Abstract: Objective To evaluate endoscopic ultrasound for preoperative staging of ampullar tumors.Methods A total of 31 patients with ampullar tumors who underwent surgery from 2010 to 2015 were retrospectively reviewed.B-US,CT,MRCP and EUS were performed in all patients.The diagnostic rates of EUS and other imaging technology,and the diagnostic accuracy of preoperative staging and postoperative pathological staging were compared.Results Diagoses of 31 patients of ampullar tumors patients undergoing preoperative endoscopic ultrasonography assessment T staging were as the following:uT1,4 cases; uT2,15 cases; uT3,10 cases; uT4,2 cases.Compared with the postoperative pathological diagnosis,the T staging accuracy was 90.3％ (28/31),anong which 1 case was overestimated,2 cases were underestimated.The accuracy of endoscopic ultrasound in preoperative diagnosis of ampullar lesions was superior to other detection technology.Conclusion EUS is a valuable diagnostic tool for patients with suspected ampullar tumors.
