Summary

The aim of this study was to assess the biomechanical properties of the transversalis fascia and rectus abdominis aponeurosis (rectus sheath) in inguinal herniation. These tissues were evaluatedex vivo on fresh samples from 36 patients with inguinal hernias and 11 controls without hernias using a Cutometer® equipped with a 2-mm probe. Under 50 mbar suction, the control aponeurosis and transversalis fascia revealed identical extensibility but the visco-elastic ratio was markedly increased in fascia (p<0.001). The elasticity was significantly higher in the aponeurosis (p<0.01). Differences between control and patient aponeuroses were not statistically significant. No significant biomechanical differences were observed between fasciae from controls and from indirect hernias. However, the extensibility and elasticity of fasciae from direct hernias were significantly increased (p<0.0001 and p=0.01 respectively), as compared with control fasciae. These preliminary results need to be confirmed: we are currently involved in this project.
