Mile’s手术为常用直肠癌根治术式。但Mile’s术后遗留的骶前会阴部残腔,难以闭合,且多并发感染,使创面长期不愈。半个世纪来,国内外医务工作者虽几经研究,至今仍无理想的处理方法。主要原因是直肠切除后留下之巨大残腔易积液和并发感染。针对这种情况,我们采用转移臀大肌瓣充填骶前腔、充分引流、积极预 Mile’s surgery is a commonly used radical resection of rectal cancer. However, the residual cavity of the perineum before Mile’s surgery is difficult to close, and there are multiple concurrent infections, resulting in long-term unhealed wounds. In the past half century, although medical workers at home and abroad have studied several times, there is still no ideal way to deal with it. The main reason is that the huge residual cavity left after rectoectomies is prone to effusion and concurrent infection. In response to this situation, we used the transfer of gluteus maximus muscle flap to fill the anterior tibial cavity, adequate drainage, and aggressive preconditioning.
