传统的经腹会阴直肠癌切除术有导致泌尿系及性功能损害的可能,围绕直肠直视下沿壁层盆盘膜锐性分离可不损伤处主神经而避免上述并发症。作者为此进行了男女各3例盆区矢状切面尸体解剖以深入了解有关解剖。 结果 6例所见一致。直肠与骶骨间有一易剥开的潜在间隙,前后壁分别为盆筋膜前叶(脏层)和后叶(壁层);前者与其所覆盖的肠外脂肪组成直肠系膜,后者则覆盖梨状肌、尾骨肌和肛提肌,并在一些部位与骶骨骨膜紧密相连。间隙侧方为髂内动脉,尾
Traditional transperineal rectal cancer resection may lead to urinary system and sexual dysfunction. Around the rectum, the sharp separation of the pelvic disc along the parietal layer can avoid the complications without damaging the main nerve. The authors conducted 3 cases of pelvic sagittal section autopsies for men and women to learn more about the anatomy. The results were consistent in all 6 cases. There is a potential gap between the rectum and the sacrum that is easily peeled off. The anterior and posterior walls are the anterior (pelvic) and posterior (wall) layers of the pelvic fascia; the former consists of the extra-intestinal fat that covers the mesorectum and the latter covers the pear. Muscles, coccygeus, and levator ani muscles, and in some areas are tightly connected to the periosteum of the tibia. The side of the gap is the internal iliac artery, tail
