该文将６０例结肠癌梗阻病人随意分为实验组和对照组，实验组行大肠次全切除一期吻合３０例；对照组行传统的术式或左半结肠切除一期吻合３０例。经１～６年随访观察对比，结果发现两组的手术成功率，术后并发症以及生活质量有明显的区别。两组死亡率差异有显著性（Ｐ＜０．０５），特别是复发或转移死亡＜６０岁的癌患者的死亡率有显著性差异（Ｐ＜０．０１），从５年成活率以及组织类型上分析，两组术式及其预后亦有明显区别。 This article randomly divided 60 cases of colon cancer obstruction patients into the experimental group and the control group, the experimental group underwent subtotal anesthesia 30 cases of primary anastomosis; the control group underwent conventional or left hemicolectomy anastomosis in 30 cases. After 1 to 6 years of follow-up observation and comparison, it was found that the success rate of the two groups, postoperative complications and quality of life are significantly different. There was a significant difference in mortality between the two groups (P<0.05), especially in patients with recurrence or metastasis <60 years of age with significant difference in mortality (P<0.01), survival rate from 5 years and organization Types of analysis, the two sets of surgical methods and their prognosis are also significantly different.
