Three-dimensional reconstruction under computed tomography and myopectineal orifice measurement under laparoscopy for quality control of inguinal hernia treatment

Figure 2 The four anatomical landmarks used to determine the boundaries of the myopectineal orifice. Before the operation, point A is the innermost edge of the iliopsoas muscle; point B is the lowest point of the transverse abdominal muscle; point C is the intersection point of the horizontal line passing through point A and the iliopsoas muscle; and point D is the intersection point of the vertical line passing through point B and the pubis.
