Adhesion prevention in ventral hernia repair: an experimental study comparing three lightweight porous meshes recommended for intraperitoneal use

Abstract

The combined porous meshes tested in the present study demonstrated to reduce but not to prevent the adhesion formation, even if with some differences. Combined porous meshes could be chosen instead of simple meshes for retro-rectus preperitoneal prosthetic ventral hernia repair.

Two cases about mesh adhesion to intra-abdominal cavity tissue after using mesh to repair incisional hernia

“…18,20 Although lower than in OVHR, the hernia recurrence rate after LVHR has been reported to be up to 9%. 19 Since they are allogeneic, a prosthetic could lead to inflammation resulting in permanent adhesions between the mesh and abdominal viscera, 21,22 especially if it is located intraperitoneally. Adhesion may cause serious complications including chronic pain, intestinal obstruction and enterocutanic fistulae.…”

“…Adhesion may cause serious complications including chronic pain, intestinal obstruction and enterocutanic fistulae. [22][23][24] Traditional meshes are made of propylene: whilst this is strong and stable, it easily causes adhesion. 22,25,26 When adhesion occurs, it is recommended to implant an anti-adhesion mesh, a novel prosthesis coated in a material to lower adhesion.…”

“…[22][23][24] Traditional meshes are made of propylene: whilst this is strong and stable, it easily causes adhesion. 22,25,26 When adhesion occurs, it is recommended to implant an anti-adhesion mesh, a novel prosthesis coated in a material to lower adhesion. Using an anti-adhesion mesh for repair could reduce the risk of recurrence, infection, inflammation and pain, which can improve patients' post-operative life quality.…”

Biomaterial Implants in Abdominal Wall Hernia Repair: A Review on the Importance of the Peritoneal Interface

“…They can also include an absorbable material in thread form knitted together with a synthetic reticular permanent mesh [98]. However, these meshes have not either showed an acceptable performance regarding adhesion formation [99][100][101][102] since the reticular/protruding profile of the mesh provokes peritoneal damage even when an inert material is employed. The injury to the peritoneum is the event that triggers the coagulation cascade and the genesis of adhesions in a case of persistent inflammation.…”
