Types of mesh in hernia repair?

In hernia repair, various types of mesh materials can be used to reinforce the weakened or damaged tissue. These meshes provide additional strength and support to the repaired area, promoting healing and reducing the risk of hernia recurrence. Here are some common types of mesh used in hernia repair:

1. Synthetic Mesh:

a) Polypropylene Mesh: This is the most commonly used synthetic mesh in hernia repair. It is lightweight, strong, and has good tissue compatibility. Polypropylene mesh is resistant to infection and degradation over time.

b) Polyester Mesh: Polyester mesh is another commonly used synthetic material for hernia repair. It is flexible, durable, and has high tensile strength. It can be a good option for patients with allergies to polypropylene.

c) Polytetrafluoroethylene (PTFE) Mesh: PTFE mesh, also known as Gore-Tex mesh, is a non-absorbable, synthetic material. It is flexible and has a low tissue reaction, making it suitable for patients who may be sensitive to other mesh types.

2. Biologic Mesh:

Biologic meshes are made from natural or animal-derived materials and are designed to be absorbed or replaced by the body's own tissues over time. They can be advantageous in certain situations, such as contaminated wounds or when tissue integration is desired.

a) Collagen Mesh: Collagen mesh is made from purified animal collagen. It is biocompatible and gradually resorbed by the body, leaving behind host tissue that provides continued support.

b) Porcine Small Intestinal Submucosa (SIS) Mesh: SIS mesh is derived from the submucosa layer of pig intestines. It is bioresorbable and promotes tissue regeneration, leading to eventual replacement with the host's own tissue.

3. Hybrid Mesh:

Hybrid meshes combine synthetic and biologic materials to leverage the advantages of both types. They may consist of a synthetic mesh coated with a biologic layer to improve tissue integration and reduce foreign body reactions.

The type of mesh used in hernia repair depends on various factors, such as the type and size of the hernia, the patient's overall health, and the surgeon's preference and expertise. The choice of mesh is made with the aim of providing optimal support and reducing the risk of complications.
