摘　　要：体表超声检查４７例腹段食管癌（含１４例贲门癌侵及食管），其中３９例显示食管壁增厚，均值为９．３３（±３．７２）ｍｍ，有３２例显示内腔回声异常；２７３例正常人超声普查，结果见２２１例清晰显示食管壁正常，均值为２．５７（±０．５５）ｍｍ，有２２３例显示内腔回声正常。超声对腹段食管癌诊断的灵敏度达８３％（３９／４７），特异性达８１％（２２２／２７５）．诊断正确率达８１％（２６１／３２２）。超声亦可显示淋巴结肿大及食管癌向周围组织浸润或远处转移的情况，有较高的临床应用价值。Forty-seven cases of esophageal cdrcinoma involving the abdominal segment(in-cluding 14 cases of cardial carcinoma with esophageal involvement)were examined by body surface ultrpasonography.Among them.39 cases showed thickening of the esophageal wall with a meanvalue of 9.33(±3.72)mm,32 case:of them presented an abnormal echo of internal lumen. 273 cases of normal individuals were subjected to ultrasound screening,of whom 221 cases demonstrated clearly visualized nomal esophageal wall with a mean value of 2.57±0.55mm and other 2 cases were mis-diagnosed as a normal status and esophageal tumor respectively.The sensitivity for the diagnosis of esophageal carcinoma in abdominal segment by ultrasonography reached 83%(39/47),the specificity 81%(227/275) and diagnostic accuracy 81%(261/322).Besides,ultrasonography could disclose en-larged lymph node,surrounding infiltration or distant metastasis and therefore is valuable in clinical application.
