Using a synthetic mesh to repair an incisional hernia reduces tension at the surgical wound and prevents recurrence.
Synthetic mesh allows defects of any size to be repaired without tension with a low recurrence rate.
Synthetic mesh is a weave, usually of a synthetic material called polypropylene, which looks like the mosquito-net or wired-screens on the window and doors. The mesh is used to patch an area. The idea is that if the cut ends of the surgical defect are sewn back together, tension may be present at the repair site. In addition, the pressures that led to the hernia in the first place are still present. And together, the tension on the repair and the pressures that caused the hernia can cause the hernia to recur.
The use of the synthetic mesh provides a tension free repair and provides the added support to the weak wall of the abdomen.
Mesh and infection
Any foreign material placed in the body is a potential source for infection. Due precautions need to be exercised before and during surgery to prevent infections.
In the current era where almost everything used in operation theatre is disposable the incidence of infection is low. However if does happen the mesh may need to be removed. Sometimes the mesh may erode through the skin or into the intestine.
