BACKGROUND/AIMS: We studied the effectiveness of ultrasonography in evaluating the cervical esophagus for the presence of large masses arising from the esophageal wall and consequently, the modifications of the visceral lumen. MATERIALS AND METHODS: The cervical esophagus can be evaluated by ultrasound with longitudinal and axial scans, using the left thyroid lobe as an acoustic window. The cervical esophagus can be visualized from the C5 to D2 vertebrae. From November 1992 to July 1996, 220 patients with esophageal cancer and 120 subjects without esophageal disease (control group) were examined with ultrasonography. Examination of the cervical esophagus was performed with a linear high definition small parts probe with a frequency of 7.5-10 Mhz. RESULTS: In all 31 patients with cancer of the cervical esophagus, ultrasonography of the cervical region showed the presence of an expanding mass from the esophageal wall as well as the modifications in the visceral lumen. The neoplasm of the cervical esophagus was visualized when its diameter exceeded 5 mm. CONCLUSIONS: The experience of the authors shows that, during ultrasound examination of the cervical region, it is possible to accurately evaluate the cervical esophagus, either morphologically or functionally.
