    Abstract:
    Surgery for esophageal cancer carries a high mortality rate and a low rate of resectability for cure. Accurate preoperative staging is therefore of utmost importance. Staging is based on computerized tomography (CT), and recently, the use of endoscopic ultrasonography (EUS). We performed EUS and CT on 10 patients with esophageal cancer. Tumors were staged according to the TNM classification. According to the CT results, seven patients had a T3 tumor, one T1-2 and two T0. All patients were diagnosed as T3 by EUS. One patient, who was treated by combined modality treatment with chemotherapy and radiotherapy, converted to T0. Six patients were operated on, and in five, pathological findings were of an invasive tumor. The T stage was predicted correctly in five patients by CT and in all six patients by EUS. N stage was correctly diagnosed in two patients by CT and in five by EUS. It is concluded that EUS is superior to CT for preoperative staging of esophageal tumors. EUS should be undertaken as a routine procedure prior to surgery for esophageal cancer.
