Totally Extraperitoneal Herniorrhaphy (TEP): Lessons Learned from Anatomical Observations

Figure 3

Schematic illustration of a horizontal section of the lower abdominal wall (Retzius’ and Bogros’ space). (a) The red arrows illustrated the approach path into the Bogros space, which communicated these two discontinuity planes for spreading the position of mesh. (b) The position of mesh (dashed line), i.e., placing between the transversalis fascia and the superficial layer of preperitoneal fascia in the Retzius’ space, the deeper layer of preperitoneal fascia, and the peritoneum in the Bogros’ space.
