Why Mesh?
Low recurrence rate Inguinal hernia repair
Bassini’s repair : 10% Shouldice repair : 1% Lichtenstein’s Mesh repair : <1%
Ventral hernia Suture Vs Mesh: : 50% Vs 10%
Tension free & Pain free Quick recovery Quick to learn and easy to do!

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)

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’’.

What MeshLight 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 FlexibleLess FB reaction and pain
StifferMore FB reaction and pain(Problem of adhesion, fistula)Shrinks moreStronger! - so what

Mesh Related Complications…
Infection Surgeon’s nightmare
Intestinal adhesions Composite mesh for laparoscopic ventral hernia repair
Bowel obstructions
Erosion of the prosthesis into the adjacent hollow viscus
Contraction of prosthesis At least 5cm larger than the size of the defect

Prevention of Mesh infectionConsider
Patient factors Smoking DM Obesity Re operation Big incision
Type of Mesh Macroporous vs microporous Impregnated mesh
Technique Lap Vs Open On lay Vs In lay
Prophylactic antibiotics Avoid unplanned
enterotomy Infected field
Absorbable mesh Biological mesh
Ventral hernia repair•Risk of infection is 3-10% in Open mesh repair•Risk of infection is < 1% in Lap Mesh repair

Conclusion
Mesh repair of abdominal wall hernia is the Standard of Care.
Composite mesh has to be used for ventral hernia
Avoid Mesh related complications , if possible
