本文对26例小肠肿瘤患者进行了二维及彩色多普勒超声检查,部分患者采用高频探头,其结果分别与消化道钡餐检查及病理对照。分析良、恶性小肠肿瘤的超声图像,提出超声诊断的声像图特征,评价其临床应用价值。 资料与方法 本组26例小肠肿瘤均经超声检查并手术或穿刺后病理证实。男性17例,女性9例,年龄13～75岁,平均年龄44岁。良性6例,恶性20例。病程自症状出现后3天至2年,临床表现有不同程度的腹痛、腹胀、间歇性肠梗阻、黄疸、呕吐及黑便,部分可扪及腹部包块并发现其它脏器转移。 采用Aloka SSD 1200型灰阶超声仪,东芝340A彩色超声诊断仪,探头频率为7.5MHz及3.5MHz。
In this paper, 26 cases of small bowel cancer patients underwent two-dimensional and color Doppler ultrasound, some patients with high-frequency probe, the results were digestive tract barium meal examination and pathological control. Ultrasound images of benign and malignant small bowel tumors were analyzed, and sonographic features of ultrasound diagnosis were proposed to evaluate their clinical value. Materials and Methods The group of 26 cases of small bowel tumors were confirmed by ultrasound and pathology after surgery or puncture. 17 males and 9 females, aged 13 to 75 years, mean age 44 years. 6 cases of benign and 20 cases of malignant. Course of disease since the symptoms appear 3 days to 2 years, the clinical manifestations of varying degrees of abdominal pain, abdominal distension, intermittent intestinal obstruction, jaundice, vomiting and melena, some palpable abdominal mass and found that other organ metastases. Using Aloka SSD 1200 gray-scale ultrasound system, Toshiba 340A color ultrasonic diagnostic apparatus, the probe frequency is 7.5MHz and 3.5MHz.
