总结我院１９７５年６月～１９９１年１２月手术治疗直肠癌１００２例，其中单纯造瘘术１０５例，姑息性手术１０４例，一般根治术４９１例，扩大根治术３０２例。分析结果如下：直肠癌淋巴转移率为４５．３％，转移度８．９％。上方途径第三站转移率为１０％，而侧方转移仅发生于腹膜返折以下的癌，侧方第三站转移率为１０％。因此我们主张按此淋巴转移规律进行扩大淋巴清除术，其中５年生存率达６８％，１０年生存率达４７％，生存率明显高于其他术式（Ｐ＜０．０１）。通过直肠癌壁内逆向浸润研究，指出逆向浸润的平均距离为２．４ｃｍ，并以此规律指导直肠癌的保肛手术。对直肠癌术后局部复发、肝转移、早期癌及功能性直肠癌手术提出了外科治疗原则，得到良好效果。
Summarize our hospital from June 1975 to December 1991 surgical treatment of rectal cancer 1002 cases, including 105 cases of simple ostomy surgery, 104 cases of palliative surgery, 491 cases of general radical surgery, extended radical mastectomy 302 cases. The analysis results are as follows: The lymphatic metastasis rate of rectal cancer was 45.3%, and the degree of metastasis was 8.9%. The transfer rate at the third station of the upper route was 10%, while the lateral transfer occurred only in the cancers below the peritoneal fold. The third site transfer rate was 10%. Therefore, we advocate that lymphatic metastasis should be carried out according to the law of lymphatic metastasis. The 5-year survival rate is 68%, and the 10-year survival rate is 47%. The survival rate is significantly higher than other surgical procedures (P<0.01). Through the study of retrograde infiltration of rectal cancer, the mean distance of reverse infiltration was 2.4 cm, and this rule guided rectal cancer preservation. The principles of surgical treatment for local recurrence, hepatic metastasis, early cancer and functional rectal cancer surgery for rectal cancer have been proposed and good results have been obtained.
