著者举出许多学者的经验,说明有肝、肺转移的结肠和直肠癌患者,如能作原发癌的姑息性切除术,其生存期几乎可以延长一倍左右。著者的2.160例患者中,作姑息性切除者310例(16.8％),本文选择其中一部分患者分5组进行分析。甲组:50例单纯肝转移患者,接受了原发癌姑息性切除术,手术死亡率4％(2例),其余48例平均生存期为15.1月,其中1例生存10年以上,2例生存5年以上。术后患者主观症状反应优良者11例,良好者20例,尚好者10例,不佳者7例。能恢复一定期间的一定工作者占68.5％。乙组:25例单纯肝转移患者,有完全性结肠梗阻 The author cites the experience of many scholars, indicating that patients with colon and rectal cancer who have liver and lung metastases, such as palliative resection of primary cancer, can almost extend their survival time by about one time. In the author’s 2.160 patients, 310 cases (16.8%) were palliative resections. This article selected some of them to be divided into 5 groups for analysis. In group A, 50 patients with simple liver metastases underwent primary palliative resection. The mortality rate was 4% (2 cases). The remaining 48 cases had an average survival period of 15.1 months. One case survived more than 10 years and 2 cases. Survive for more than 5 years. Among the patients, 11 had good subjective symptoms, 20 had good results, 10 had good results, and 7 had poor results. A certain number of workers who can restore a certain period account for 68.5%. Group B: 25 patients with simple liver metastases, with complete colonic obstruction
