Abstract: Objective To evaluate mechanical radial scanning endoscopic ultrasonography (EUS) for preoperative tumor and lymph node ( TN ) staging of esophageal cancer. Methods From January 2010 to June 2010, a total of 60 patients with esophageal cancer underwent preoperative staging with mechanical radial scanning EUS. The findings of EUS were compared with postoperative pathological outcomes. Results EUS accurately predicted T stage in 80 % of cases and N stage in 71% cases. Sensitivities to T1 , T2 , T3 and T4 were 75% , 100% , 96% and 50% , respectively, and those to N0 and N1 were 55% and 100% , respectively. With exclusion of 11 patients with un-passable lesions, the accurate rate of EUS in T staging of focal and advanced cancers was 90% ( 44/49 ). Conclusion Mechanical radial scanning EUS can accurately predict T and N stages in preoperative patients with esophageal cancer, which also exhibits high differential accuracy in focal and advanced esophageal cancer.
