[Contribution of endo-sonography in the evaluation of cancer of the esophagus].
Images of endoscopic ultrasonography are compared with data of surgery and histology. As to tomodensitometry, endoscopic ultrasonography has proved to be more accurate in study of penetration into the esophageal layers, of extension to surrounding structures, specially peri-esophageal lymph nodes. In contrast, endoscopic ultrasonography is helpless searching distant lymph nodes involvement and metastases. These new imaging techniques, together with tracheo-bronchoscopy, enable high degree of precision in determination of the extent of the tumor. Despite better accuracy of the staging, surgical indications remain controversial.
