已公认直肠癌肿位于上1/3段可作修复性前切除,下1/3段作经腹会阴切除。但对中1/3段的手术方法则尚未取得一致的意见。从技术上来看,采用钉书机缝合器便于切除中1/3段直肠癌肿后的吻合,但这一修复性切除是否能达到与经腹会阴全切除相似的疗效尚未定论。为此,作者对这二种手术后的远期疗 It is generally accepted that rectal cancer swollen in the upper 1/3 segment can be used for repair anterior resection and the lower 1/3 segment for abdominal perineal resection. However, no consensus has yet been reached on the surgical method for the mid-1/3 segment. From a technical point of view, the use of stapler stitching device facilitates resection of anastomosis after mid-third rectal cancer, but it is unclear whether this repair resection can achieve a similar effect as total resection of the abdominal perineum.
