Methods of life-time studies of lymph drainage in the rectum using lymphoscintigraphy were developed. The normal rectum was found to fall into two segments with a border at the level of 5 cm above the anus which revealed essentially different pathways of lymph drainage: mainly to inguinal and internal iliac lymph nodes (distal segment) or to superior rectal and inferior mesenteric lymph nodes (proximal one). Rectal cancer involves the switching-on of reserve and collateral pathways of lymph drainage from the organ which is determined by the local-regional extension of tumor.
开发了使用淋巴闪烁造影术对直肠淋巴引流进行终身研究的方法。发现正常直肠分为两段，边界位于肛门上方5厘米处，这两段显示出基本不同的淋巴引流途径：主要引流至腹股沟和髂内淋巴结（远端段）或至直肠上和肠系膜下淋巴结（近端段）。直肠癌涉及开启该器官淋巴引流的储备和侧支途径，这由肿瘤的局部区域扩展决定。
