腹腔镜低位直肠癌术中保护盆丛及其血管神经束要点

Preservation of pelvic plexus and neurovascular bundles in the laparoscopic sphincter-preserving surgery for low rectal cancer

目前,腹腔镜手术在直肠癌中的应用越来越广泛,如何在腹腔镜低位直肠癌保肛术中保护盆丛及其血管神经束是手术的关键与难点,也是关系到病人术后排尿及性功能正常与否的重要因素。由于腹腔镜下所呈现的解剖结构与开放手术所见有很大的不同,在腹腔镜低位直肠癌保肛手术中认识这些重要结构并找到正确的解剖层面,方能达到最佳的保护神经效果。

Recently,more and more laparoscopic surgery is applied to treat the rectal cancer. The preservation of pelvic plexus and neurovascular bundles is the key and difficult part of the laparoscopic sphincter-preserving surgery for low rectal cancer,and it is the important factor of postoperative urinary and sexual function. Because of the different appearance of laparoscopic anatomy compared to the open surgery,recognizing the structures and finding the correct surgical plane during laparoscopic rectal surgery will help preserve related nerve structures.
