[The study of transesophageal ultrasonography in assessing operability of the advanced esophageal carcinoma].
Abstract sixty-one advanced esophageal carcinoma patients were examined by transesophageal ultrasonography (TEUS), in which fifty three squamous cell carcinomas and eight adenocarcinomas were diagnosed by pathology. There were clearly demarcated spaces between the tumours and the important adjacent structures in the local resectable fourty-two of fourty-eight cases. On the contrary, the ultrasonic images of the non-resectable ten cases showed the unclear demarcation between the tumours and thoracic aorta, pulmonary vein, pericardium and so on in several images. The study discovered the interruption of the regional echo of the normal aortic wall where the hypoechoic area took instead of aortic wall echo in several patients. The squeezed signs of the tumours to the aortic wall might be shown. These signs demonstrated tumour invading severely the aorta. Three cases of metastasis of liver were not operated on. Six patients failed to predicted accurately because the stenosis could not be passed with TEUS. The accurate a assessing the operability of those cases with TEUS was 85.2%. So TEUS is a useful, simply, reliable method for the assessing the operability of esophageal carcinoma.
