This was a prospective study of postmenopausal women who underwent a computerized tomography (CT) examination of the abdomen and pelvis. We evaluated the location of the aortic bifurcation and transverse colon relative to the umbilicus at midline axis. Of 66 women, 24 were of normal weight, 23 were classified as overweight, and 19 as obese. The ages of the women in all groups were comparable. In the normal weight and overweight women, the mean location of the umbilicus was 0.6 cm +/- 0.4 cm and 0.4 cm +/- 0.3 cm cranial to the aortic bifurcation, respectively, and in obese women its mean location was 1.4 cm +/- 0.5 cm caudal to the aortic bifurcation. In approximately half of the normal weight and overweight women, the umbilicus was located cranial to the aortic bifurcation, and in 62.2% of obese women it was located caudal to the aortic bifurcation. Compared to those with normal weight (0.3 cm +/- 1.1 cm), the distance between umbilicus and transverse colon was greater in overweight (4.5 cm +/- 1.2 cm) and obese women (7.1 cm +/- 0.7 cm). In approximately one third of the normal weight women and over half of the overweight women, the umbilicus was located caudal to the transverse colon. In contrast, the umbilicus in 84.2% of the obese women was located caudal to transverse colon. There was a linear correlation between the distance of umbilicus and transverse colon distance and body mass index (BMI; r = 0.54, p < 0.0001). Regardless of the BMI, there was a wide variability whether the umbilicus was cranial or caudal to the aortic bifurcation or transverse colon. Similar to that in reproductive-aged women, in postmenopausal women the location of the aortic bifurcation and transverse colon varies. Proper insertion of the Veress needle and trocar is more important than a particular angle of insertion.
这是一项针对接受腹部和盆腔计算机断层扫描（CT）检查的绝经后女性的前瞻性研究。我们评估了主动脉分叉和横结肠在中线轴上相对于脐部的位置。66名女性中，24名体重正常，23名被归类为超重，19名肥胖。所有组中女性的年龄相当。在体重正常和超重的女性中，脐部的平均位置分别在主动脉分叉上方0.6厘米±0.4厘米和0.4厘米±0.3厘米处，而在肥胖女性中，其平均位置在主动脉分叉下方1.4厘米±0.5厘米处。在大约一半的体重正常和超重女性中，脐部位于主动脉分叉上方，而在62.2%的肥胖女性中，脐部位于主动脉分叉下方。与体重正常的女性（0.3厘米±1.1厘米）相比，超重（4.5厘米±1.2厘米）和肥胖女性（7.1厘米±0.7厘米）中脐部与横结肠之间的距离更大。在大约三分之一的体重正常女性和超过一半的超重女性中，脐部位于横结肠下方。相比之下，84.2%的肥胖女性的脐部位于横结肠下方。脐部与横结肠之间的距离与体重指数（BMI；r = 0.54，p < 0.0001）之间存在线性相关性。无论BMI如何，脐部位于主动脉分叉或横结肠上方还是下方都存在很大差异。与育龄女性相似，绝经后女性中主动脉分叉和横结肠的位置也会变化。Veress针和套管针的正确插入比特定的插入角度更重要。
