Composite meshes (for intraperitoneal use)
| Type of mesh | Pore size | Absorbable | Weight | Comments | |
|---|---|---|---|---|---|
| Multi | |||||
| Vypro, Vypro II (Ethicon) | Prolypropylene/PG910 | Large > 3 mmm | Partially (42 days) | Light-weight 25 & 30 g/m2 | First light-weight meshes with large pores. Vypro not strong enough for incisional hernias (use Vypro II) |
| Gortex Dual Mesh & Dual Mesh Plus (Gore) | ePTFE | Very small 3/22 μm | No | Heavy-weight | Different sized pores for each side. Dual Mesh Plus is impregnated with antiseptic to minimise infection |
| Parietex (Covidien) | Polyester/collagen | Large > 3 mm | Partially (20 days) | Medium weight 75 g/m2 | Bovine collagen coating and anti-adhesion film of polyethylene glycol and glycerol. ?Only short-term benefit for anti-adhesional property16 |
| Mono | |||||
| Composix EX Dulex (BARD) | Polypropylene/ePTFE | Medium 0.8 mm | No | Light-weight | Two distinct surfaces, overlap of ePTFE stops adhesions at the edges |
| Proceed (Ethicon) | Polypropylene/cellulose (ORC) | Large | Partially (< 30 days) | Light-weight 45 g/m2 | 3-layer laminate with PP; oxidised cellulose (absorbable) and polydioxanone film (not absorbed) |
| Dynamesh IPOM (FEG Textiltechnik) | Prolypropylene/PVDF | Large 1–2 mm | Partially | Medium weight 60 g/m2 | PVDF causes minimal foreign body reaction |
| Sepramesh (Genzyme) | Prolypropylene/sodium | Large 1–2 mm | Partially (< 30 days) | Heavy-weight 102 g/m2 | Seprafilm turns to gel in 48 h and remains on mesh for 1 week to allow re-epithelisation. ?Only short-term benefit for anti-adhesional property hyaluronate16 |
| Ultrapro (Ethicon) | Polypropylene/polyglecaprone (Monocryl) | Large > 3 mm | Partially (< 140 days) | Light-weight 28 g/m2 | Monocryl has a combination of polymers; e-caprolactone, which is malleable and polyglycolide, which is strong. Less inflammatory response than Vicryl |
| Ti-mesh (GfE) | Polypropylene/titanium | Large > 1 mm | No | Light-weight and extra-light 16 & 35 g/m2 | Possibly has a reduced inflammatory response compared to other meshes (?biologically inert)34 |
| C-Qur (Atrium) | Polypropylene/omega 3 | Large > 1 mm | Partially (∼120 days) | Medium-weight 50 g/m2 | Omega 3 from fish oils ?Only short-term benefit for anti-adhesional property16 |
