What is surgical mesh?
Surgical mesh is a thin, flexible material used to reinforce the abdominal wall during hernia repair. It has been used for decades and is the most extensively studied component of modern hernia surgery.
Why mesh is used
For most adult hernias, mesh-based repairs have substantially lower recurrence rates than tissue-only (suture) repairs. Mesh allows the surgeon to bridge or reinforce the fascial defect without putting the repair under tension — and tension is a key driver of recurrence.
Types of mesh
- Permanent synthetic mesh (most commonly polypropylene)
- Absorbable synthetic mesh
- Biologic mesh (animal- or human-derived)
- Hybrid mesh combining permanent and absorbable components
Mesh also varies in weight, pore size, and coating. Lightweight, large-pore meshes are commonly chosen for groin and many ventral hernia repairs because they integrate well and are typically comfortable long-term.
Common questions about mesh
- Is mesh always required? No. Small umbilical defects and some pediatric repairs can be repaired without mesh. For most adult hernias, mesh significantly reduces recurrence.
- Is mesh safe? Modern mesh is well-studied. Major surgical societies continue to recommend mesh for most adult hernia repairs. Specific products have been withdrawn over the years, but mesh use overall remains evidence-supported.
- Will I feel the mesh? Most patients do not feel mesh once healing is complete. A minority develop chronic pain, which can have multiple causes beyond mesh itself.
Potential risks
As with any implant, mesh carries risks including chronic pain, infection, adhesions, seroma, mesh migration, and — rarely — erosion into adjacent structures. Risk varies by mesh type, placement, surgical technique, and patient factors.
Talking to your surgeon
Patients should feel empowered to ask which mesh is being proposed, where it will be placed, what alternatives exist, and what the surgeon's personal recurrence rate is for this type of repair.
