Abstract:
Objective To assess the clinical value of endoscopic uhrasonography(EUS)combined with the mini-probe endoscopic uhrasonography(MPUS)in determing tumor invasion depth and lymph node metastases of early superficial esophageal cancer.Methods One hundred and twenty-four superficial esophageal cancer lesions of 121 patients were staged by EUS combined with MPUS,and the results were finally compared with pathological findings of surgical specimens or samples obtained by mucosal resection.Results The diagnostic accuracy of EUS in T staging of superficial esophageal cancer was 82.3%(102/124).The total ratio of lymph node metastases was 5.0%(6/121),with no node metastases in carcinoma in situ,1.3%(1/28)in mucosal carcinoma,11.6%(5/43)in submucosal carcinoma.Conclusion EUS combined with MPUS is accurate in staging of the superficial carcinoma,which can help the choice of therapeutic strategies.
