目的研究B型超声在观察消化道恶性肿瘤患者腹腔淋巴结转移中的价值。方法回顾分析74例消化道恶性肿瘤患者伴腹腔肿大的淋巴结声像图,并对其特点进行综合分析。结果各类消化道恶性肿瘤晚期腹腔淋巴结转移是最常见的特征,超声能够准确的显示淋巴结的位置、大小,并能显示淋巴结宽径的明显增大,淋巴结内部回声片状改变、变形等特点,并可挤压周围血管、与之粘连等;彩色多普勒显示淋巴门消失或变小。结论对腹腔淋巴结肿大的声像图特征和发生部位进行分析,有利于肿瘤的定位、定性诊断,具有为临床选择治疗方案和判断预后提供可靠依据的重要意义。
Objective To study the value of B ultrasound in the observation of abdominal lymph node metastasis in patients with gastrointestinal cancer. Methods A retrospective analysis of 74 cases of patients with gastrointestinal cancer with enlarged abdominal lymph nodes sonograms, and its characteristics were analyzed. Results All kinds of digestive tract malignant tumors were the most common features of late stage lymph node metastasis. Ultrasound could accurately display the location and size of lymph nodes, and could obviously show the widened lymph node width, the change of echogenic lamellar and the deformation of lymph nodes. And can squeeze the surrounding blood vessels, adhesion and so on; color Doppler lymph glands disappear or become smaller. Conclusion The analysis of the features and location of the abdominal lymph node enlargement is helpful for the localization and qualitative diagnosis of the tumor. It is of great significance to provide a reliable basis for clinical choice of treatment and prognosis.
