临床医师可根据盆腔自主神经(PANP)的解剖特点探讨保留自主神经的直肠癌根治术,对男性术后的排尿功能及性功能的保护作用。直肠系膜及周围筋膜在多层螺旋CT(MSCT)图像上能够显示,侧方筋膜显示率高于前、后筋膜,直肠系膜CT值高于盆壁脂肪,其差异肉眼可辨,直肠癌患者直肠系膜的密度高于正常,可以较准确地评价中晚期直肠癌侵犯直肠周围筋膜情况,并对外科术前手术方式的选择有指导价值。
According to the anatomic features of pelvic autonomic nerve (PANP), clinicians can explore the radical mastectomy for preserving the autonomic nerve and the protective effect on the voiding function and sexual function of postoperative male patients. The mesorectum and its surrounding fascia showed on the MSCT images that the lateral fascia showed a higher rate than the anterior and posterior fascia and the mesorectal CT value was higher than that of the pelvic wall, The density of mesorectal cancer in patients with cancer is higher than normal, which can accurately evaluate the situation of rectal cancer infiltrating the peri-rectal fascia in middle and late stage, and it is instructive for the choice of surgical preoperative surgical approach.
