目的评价直肠癌病人术前淋巴管造影和放射性核素淋巴显像的临床价值。方法选择直肠癌术前病人４３例于术前一周分别行淋巴管造影１８例，放射性核素淋巴显像２５例，将结果与术后病理学检查进行比较。结果淋巴管造影符合率８８％（１６／１８）；放射性核素淋巴显像符合率５２％（１３／２５）。结论淋巴管造影，影像清晰，诊断容易，准确率高，对侧方清除及腹主动脉旁廓清有指导意义。放射性核素淋巴显像，显示淋巴区域广泛，操作简单，无并发症，但缺点是显示图像粗略，反映一组淋巴结图像，缺乏特异性。但对无淋巴结转移病例符合率较高，仍有其临床意义。
Objective To evaluate the clinical value of preoperative lymphangiography and radionuclide lymphoscintigraphy in patients with rectal cancer. Methods A total of 43 preoperative patients with rectal cancer were enrolled in this study. Eighteen lymphatic angiograms and 25 radionuclide lymphoscintigraphies were performed one week before operation. The results were compared with postoperative pathological examinations. Results The coincidence rate of lymphangiography was 88% (16/18); the coincidence rate of radionuclide lymphoscintigraphy was 52% (13/25). Conclusions Lymphangiography has clear images, easy diagnosis and high accuracy. It has guiding significance for lateral clearance and abdominal aortic paralysis. The radionuclide lymphoscintigraphy showed extensive lymphoid area, simple operation, and no complications, but the disadvantage was that the displayed image was rough, reflecting a group of lymph node images, lacking specificity. However, the coincidence rate of cases with no lymph node metastasis is still high, which still has its clinical significance.
