我院从1984年9月开始在Miles术中用结肠残端设计了新“直肠角”和用结肠浆肌层外翻卷建造人工内括约肌,在会阴部设置人工肛门。介绍了动物实验和临床对35例低位直肠癌治疗情况,经6～15月随访,效果良好。动物实验分五组,在切除肛门直肠后,用结肠残端设计了70°、90°、110°新“直肠角”和人工内括约肌,术后钡餐检查结果示 From September 1984 in our hospital, we designed a new “rectal angle” with a colonic stump in the Miles procedure, and constructed an artificial internal sphincter with the ectocyst of the colonic sarcomeres, and an artificial anus in the perineum. Introduced animal experiments and clinical treatment of 35 cases of low rectal cancer, after 6 to 15 months of follow-up, good results. The animal experiments were divided into five groups. After removing the anorectum, 70°, 90°, and 110° new “rectal angles” and artificial internal sphincter were designed with the colon stump. The results of postoperative barium meal examination showed that
