治疗低位直肠癌的标准术式是Miles(1908)首创的腹会阴联合直肠癌切除术,此手术要求行永久性乙状结肠造口。良好的造口不仅有利于近期术后恢复,而且有利于远期生活质量的提高。然而传统的结肠造口方法控便功能差,造口并发症较多。1998年1月至2006年1月,我们在进行Miles手术时采 The standard surgical procedure for the treatment of low rectal cancer is the abdominoperineal rectal cancer resection initiated by Miles (1908), which requires a permanent sigmoid colostomy. Good stoma is not only conducive to the immediate postoperative recovery, but also conducive to the improvement of long-term quality of life. However, the traditional colostomy method has poor control of fecal function and there are many complications of stoma. From January 1998 to January 2006, we were involved in the operation of Miles.
