Scintigraphic image of the superior rectal and inferior mesenteric lymph nodes 7-8 cm up from the anus was obtained by presacral administration of finely divided 99mTc-colloid (close to the posterior rectal wall). The results of radiometry of the lymph nodes dissected at radical operation for rectal cancer have shown that due to the above method the radioactive indicator is accumulated in these groups of lymph nodes. Several variants of a scintigraphic picture were defined on the basis of analysis of scintigrams of 23 patients with extrarectal tumors and nontumorous diseases and 40 rectal cancer patients. Evaluation of the lymphoscintigraphy results compared with the morphological findings of the lymph nodes dissected at operation in 32 rectal cancer patients, has shown that the overall accuracy of the above method is 0.81, specificity--0.63, sensitivity--1.0.
通过在骶前(靠近直肠后壁)注射细分的99mTc胶体,获得了距肛门7 - 8厘米处的直肠上和肠系膜下淋巴结的闪烁图像。对直肠癌根治手术中切除的淋巴结进行放射性测量的结果表明,由于上述方法,放射性指示剂积聚在这些组淋巴结中。根据对23例直肠外肿瘤和非肿瘤性疾病患者以及40例直肠癌患者的闪烁图分析,确定了几种闪烁图像变体。对32例直肠癌患者的淋巴闪烁造影结果与手术中切除淋巴结的形态学结果进行比较评估,结果表明上述方法的总体准确率为0.81,特异性为0.63,敏感性为1.0。
