对直肠中段癌有主张行Miles 手术,有主张行低位前切除或做保留肛门括约肌拖出吻合手术。我院1972～1984年选择了118例直肠中段癌病人采用低位前切除的手术方式,远期随访疗效尚好。现将有关问题报告如下。 There are advocates of Miles surgery for rectal cancer, there is a proposition to perform a low-position anterior excision or do an anal sphincter preservation anastomosis surgery. In our hospital from 1972 to 1984, 118 patients with rectal mid- cancer were treated with low-grade anterior resection. The long-term follow-up results are still good. The relevant issues are reported below.
