To investigate the application of total mesorectum excision(TME) in low pre sacrum resection (LPR) of rectum cancer. 探讨直肠系膜全切除在直肠癌低位前切除的应用。
The pelvic segment of ureter ran laterally and was far away from the mesorectum and the lateral rectal ligaments. 输尿管盆段靠外侧走行，与直肠系膜和直肠侧韧带距离较远；
The metastatic rate of LNs in the lateral ligament and in the mesorectum for tumors below the peritoneal reflection were 11.8% and 12.5%. 侧方淋巴结转移率为11.;8%25，腹膜返折下直肠周围系膜淋巴结转移率为12
Methods: In 37 cases o f rectal carcinoma, distal mesorectum (3 and 5cm below the tumor) and 10 cases of normal mesocolon, DNA index (DI), proliferation index (PI), and S-phase frac tion (SPF) were detected with flow cytometry. 方法 :采用流式细胞术对 37例直肠癌切除标本的癌组织、远端 3cm ,5cm处直肠系膜以及 10例正常结肠系膜中的DNA含量、细胞增殖活性进行检测 ,分析比较各组间DNA指数 (DI)、增殖指数 (PI)及S期细胞百分比 (SPF)等指标。
