食管癌象其他恶性肿瘤一样,在决定其病期后选择治疗手段。为了增加手术成功的机会,准确地诊断食管癌的病期是非常重要的。通常使用钡餐和上消化道内镜检查食管癌。然而,即使有这些方法,也难以准确判断食管癌的病变范围和浸润程度。使用超声内镜(EUS)不仅能诊断癌肿在壁内或食管外的浸润,还能确定食管周围淋巴结是否转移。作者等报告了用EUS 准确诊断食管癌及其病期的情况。病人和方法1983年6月至1985年10月用 EUS 检查16例食管癌(男14例,女2例)患者,年龄44～77岁(平均63.4岁)。EUS 检查前,所有病人均进行上消化道内镜检查和/或食管钡餐摄片,活检标本组织学证实为食管癌.16例中有13例经外科手术,12例比较了 EUS所见和肿瘤浸润程度之间的差异。超声内镜检查所用超声内镜有两种系列产品:一种是线形排列仪(EPB-503FL/SAL-50A,原型 V),系 Mach-ida 和 Toshiba 医疗公司联合生产;另一种是辐射扫描仪(GF-UMI/EU-M1,原型Ⅱ或 GFU-M2,
Esophageal cancer, like other malignancies, chooses treatment after determining its stage of disease. In order to increase the chance of successful operation, it is very important to accurately diagnose the stage of esophageal cancer. Barium meal and upper gastrointestinal endoscopy are commonly used for esophageal cancer. However, even with these methods, it is difficult to accurately determine the extent of lesions and infiltration of esophageal cancer. The use of endoscopic ultrasonography (EUS) can not only diagnose the invasion of the cancer in the wall or outside the esophagus, but also determine whether the lymph nodes around the esophagus are metastatic. The authors reported the use of EUS to accurately diagnose esophageal cancer and its stage. Patients and Methods From June 1983 to October 1985, EUS was used to examine 16 patients with esophageal cancer (14 males and 2 females) aged 44-77 years (average 63.4 years). Before the EUS examination, all patients underwent upper gastrointestinal endoscopy and/or esophageal barium meal examination. Biopsy specimens were histologically confirmed as esophageal cancer. Of the 16 cases, 13 were surgically treated and 12 were compared with those seen with EUS and tumors. The difference between the degree of infiltration. Ultrasound endoscopy uses two types of endoscopic ultrasonoscopes: a linear array (EPB-503FL/SAL-50A, Prototype V), produced jointly by Mach-ida and Toshiba Medical; the other is radiation scanning.
