Billroth’s Vision
‘‘If we could artificially produce tissues of the density and toughness of fascia and tendon the secret of the radical cure of hernia wouldbe discovered’’.

Inventor of Prosthetic Mesh repair: Dr. Francis Usher (1908-1980)
• Inventor of Polyehylene(Marlex) and Polypropylene mesh• Several Animal studies about their inertness• 20 papers• Innovative ways of placing the meshes: Inlay, Overlay, Sandwich tech etc

Lichtenstein’s Mesh Repair
Tension Free repair• Under LA• Day care• Low recurrence rate!
ConceiveBelieve &Achieve
Mesh is a must!
Why Mesh?
Low recurrence rate Tension free & Pain free Quick recovery Quick to learn and easy
to do!
History of Inguinal Hernia Repair
We are in Era of Tension Free Mesh Repair!

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
?Genetic defect
Connective tissue pathology is not only a cause of primary herniation but its presence can prevent cure!
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.
Why Mesh? What type of Mesh? Where to place the Mesh? How to place the place?
Types of Mesh Synthetic Mesh
Non absorbable Polyprophylene(Prolene) Polyethylene(Marlex) Polyester(Dacron) PTFE (Teflon/Gordex)
Absorbable Vicryl
Combined Vypro, Ultrapro
Synthetic with Absorbable Barrier( Dual mesh) Parietex Proceed Etc
Biological Mesh Surgisis ( Porcine submucosa) Alloderm (Cadaveric human dermis)
What Type of Mesh?Light weight Vs Heavy weight?
Light weight Mesh
Heavy weight Mesh
Definition Thin fibres, macro pores (>1.5mm)
Thick fibres, micro pores (< 1.5mm)
Qualities FlexibleLess FB reaction and pain
StifferMore FB reaction and pain(Problem of adhesion, fistula)Shrinks moreStronger! - so what

4 Absorbable tackers
For initial 1 year
5 Fibrin Glue Suitable for inguinal hernia? Ventral Hernia: Alternative or Adjunct: needs trial.Closure of Hernia defect to avoid mesh protrusion or displacement
To withstand the intra abdominal tangential force and also shearing Force due to abdominal muscle contraction
Conclusion
Mesh repair is the Standard of Care. Use Composite mesh for ventral hernia Secure the mesh to prevent recurrence
