实践证明Miles氏手术是治疗直肠下段癌的根治手术,但术后遗留永久性腹部人工肛门,使一部分患者感到精神压力很大,甚至放弃治疗。国内外少数作者报告在麦氏手术同时施行肛门成形术,既达到根治的要求,又避免了肛门改道 It has been proved that Miles’ surgery is a radical operation for the treatment of lower rectal cancer, but a permanent abdominal artificial anus is left behind, causing some patients to feel mental pressure and even give up treatment. A few authors at home and abroad reported that anal plasty was performed at the same time in Maxwell’s surgery, which not only met the requirement of radical cure, but also avoided anal diversion.
