腹股沟区的应用解剖学及其临床意义

Applied Anatomy of Inguinal Region and its Clinical Significance

目的:为临床腹股沟疝修补术提供解剖学资料。方法:选取经甲醛防腐固定的30具成人尸体,对腹股沟区逐层解剖并用三角板、游标卡尺、量角器对其进行测量和肉眼观察。结果:腹股沟韧带长(11.6±0.9)cm,宽(0.6±0.2)cm;腹股沟管长(4.6±0.6)cm;腹股沟镰长(2.1±0.8)cm。腹股沟管后壁可分为两层紧贴的筋膜层,并形成一个卵圆形的区域,其纵径长(2.8±0.8)cm,横径长(1.3±0.39)cm。结论:观测值可为临床修补术提供理论基础和实用数据。腹横筋膜深层较浅层薄弱,加强和重建腹股沟管后壁是腹股沟疝手术成败的关键。

Objective：To provide the anatomic foundmation data for clinical repair of inguinal heria. Methods：The inguinal structure of 30 adult corpses （20 males, 10 females）observed and fixed by formaldehyde was measured with set square, protractor and vernier caliper. Results： The average length of inguinal ligament was （ 11.6 ± 0.9） era, and the width was （0.6 ±0.2 ） cm. The length of inguinal canal was（4.6 ±0.6） cm and that of inguinal falx was（2.1 ±0.8） cm. The posterior wall of inguinal canal could be divided two closely-linked fascia and formed an egg-shaped area of（ 2.8± 0.8 ） cm in length and （ 1.3 ± 0.39 ） cm in width. Conclusion：These observation can supply anatomical basis and useful data for the repair of hernias in clinic. The deep layer of transverse fascia was weaker than superficial layer in these corpses. To strengthen and reconstruct the posterior wall of inguinal canal was the key point in the clinical repair of inguinal hernia.
