  • 17. Why Mesh? Pathogenesis of Hernia  Defective Collagen  Reduced ratio of type I and type III collagen  Type I: Mature Collagen, strong and normal tissue  Type III: Immature Collagen, weak, in healing wounds  Type I : Type III ratio normally is 4:1  Connective tissue pathology is not only a cause of primary herniation but its presence can prevent cure!  Increased matrix metalloproteinase activity(MMP) ‘Understand the Wound Biology’ A role for the collagen I/III and MMP-1/-13 genes in primary inguinal hernia? Raphael Rosch, Uwe Klinge, Zhongyi Si, Karsten Junge, Bernd Klosterhalfen, and Volker Schumpelick, BMC Med Genet. 2002; 3: 2.

  • 23. Types of Mesh  Synthetic Mesh  Non absorbable      Polyprophylene(Prolene) Polyethylene(Marlex) Polyester(Dacron) PTFE (Teflon/Gordex) Absorbable  Vicryl  Combined  Vipro  Synthetic with Absorbable Barrier( Dual mesh)    Parietex Proceed Etc  Biological Mesh   Surgisis ( Porcine submucosa) Alloderm (Cadaveric human dermis)
  • 24. What Mesh Light weight Vs Heavy weight? Light weight Mesh Heavy weight Mesh Definition? Light wt, thin fibres, macro pores (>1.5mm) Less amt of FB Heavy wt, thick fibres, micro pores (< 1.5mm) So more amount of FB Qualities Flexible Less FB reaction and pain Stiffer More FB reaction and pain (Problem of adhesion, fistula) Shrinks more Stronger! - so what Examples Ultrapro, Vipro Marlex, Dacron, PTEF The lightweight and large porous mesh concept for hernia repair. Klosterhalfen B, Junge K, Klinge U. Expert Rev Med Devices. 2005 Jan;2(1):103-17.
