全直肠系膜切除术中预防盆段输尿管损伤的解剖标志

Anatomic landmark to prevent intrapelvic ureteral injury during total mesorectal excision

目的:寻找全直肠系膜切除术中预防盆段输尿管损伤的解剖标志,有效地避免盆段输尿管损伤.方法:对南方医科大学附属柳州医院2006-06/2010-06施行的61例全直肠系膜切除术进行仔细地解剖标志及盆段输尿管观察.结果:61例全直肠系膜切除术中均可发现一恒定解剖结构-骶生殖襞.骶生殖襞均位于盆段输尿管与直肠系膜之间.选择在骶生殖襞的内侧层面操作,本组病例均避免了盆段输尿管的损伤.结论:骶生殖襞可以作为预防盆段输尿管损伤的解剖标志.

AIM：To find an anatomic landmark that can be used to avoid intrapelvic ureteral injury during total mesorectal excision（TME）.METHODS：Sixty-one patients undergoing TME at the Affiliated Liuzhou Hospital of Southern Medical University between June 2006 and June 2010 were observed intraoperatively to find an anatomic landmark.RESULTS：Sacrogenital folds,located between the intrapelvic ureter and mesorectum,are an anatomic structure that was observed in all the 61 cases studied.No intrapelvic ureter injury occurred when we chose to operate inside the Sacrogenital folds.CONCLUSION：Sacrogenital folds can be used as an anatomic landmark to prevent intrapelvic ureteral injury during TME.
