摘要
盆腔自主神经丛是一个立体的结构，包裹于直肠周围。在腹腔镜直肠癌手术中，有多个容易造成神经损伤的关键点。腹下神经与直肠中上段关系密切，来自骶2至骶4的盆内脏神经与腹下神经共同组成盆腔神经丛；游离直肠上段时，如错误进入盆筋膜壁层之后，则可能会将神经层掀起，造成神经损伤或离断。游离肠系膜下动脉时，应将动脉双侧可见的神经束尽量推向后腹壁，注意避免切开腹主动脉前筋膜，以免损伤神经。盆底深部直肠侧方的盆腔神经丛纤维和靠近Denonvilliers筋膜的血管神经束这两个部位也是容易受损伤的关键点，在游离直肠侧壁及前壁时，可在Denonvilliers筋膜后方、直肠固有筋膜前方进行，紧贴直肠系膜锐性离断，保护由盆腔神经丛发出的支配其他器官的分支。
Pelvic autonomic nerve is a three-dimensional structure surrounding the rectum. There are several key points related to nerve injury during laparoscopic radical resection for rectal cancer. Hypogastric nerve has close relation with the upper and middle part of the rectum. Combined with S2-S4 pelvic splanchnic nerve, hypogastric nerve forms pelvic plexus. Incorrect operation in pelvic parietal＆nbsp;peritoneum during dissection of upper rectum will lead to nerve injury. When performing dissection of inferior mesenteric artery, bilateral nerve tracts should be pushed to posterior abdominal wall and anterior fascia of the abdominal aorta should be well protected to avoid nerve injury. Pelvic plexus fibers located lateral to the rectum of pelvic floor, as well as neurovascular bundle closed to Denonvillier′s fascia, also have close relations with nerve injury. Dissection of either lateral or anterior wall of rectum should be performed behind the Denonvillier′s fascia and in front of the proper fascia of rectum. Sharp dissection should be performed closed to the mesorectum to protect branches of pelvic plexus.
