[Diagnostic value of morphological change observed by ultrasonography from skin surface in patients with cervical esophagus carcinoma].
The ultrasonography of cervical esophagus from skin surface was performed in 35 healthy adults (HA) and 46 patients with esophageal carcinoma which consisted of upper segment (USEC, n = 24) and lower one (LSEC, n = 22) divided by the level of sternoclavicular joint. The changes of the thickness of anterior wall and the luminal dimensions in the upper region were observed before and after phonating, respectively. The wall of HA was less than 2mm in thickness and became markedly thick after phonation (P < 0.05); meanwhile the lumen was evidently dilated (P < 0.01). USEC showed an irregular wall which was more than 4mm and not altered with phonation (P > 0.05). The significant differences of the above two morphologic alterations existed between HA and USEC respectively (P < 0.05 or P < 0.01). The results of LSEC were similar to HA (P > 0.05). We, therefore, establish standards for abnormal cervical esophagus to assist in the diagnosis of cervical esophageal carcinoma.
