An abdominal incisional hernia occurs in up to 5% of all cases after previous major abdominal surgery.
Where an incisional hernia recurs after a previous incisional hernia repair, the risk of a further recurrence can be as high as 40-50%.
The use of a mesh when repairing an incisional hernia, is usually advised to reduce tension in the wound when repairing such a hernia, to reduce the risk of a further recurrence.
Usually an open incisional hernia mesh repair, requires an extensive reopening of the abdominal wound and scar, in order to identify the extent of the hernial weakness, and to then suture in a place the mesh to obtain a secure and firm closure.
Both the extent of the surgical incision and the risk of the wound infection occurring are factors, which need to be considered when using an open mesh repair.
Inpatient hospital stays after open incisional hernia repair, depending on the size and extent of the incisional hernia defect, can be lengthy, and hosptal stays of 7 to10 days is not unusual.
With a laparoscopic mesh repair of an incisional hernia, only 3 or 4 small incision are made in the patients flank through which laparoscopic instruments are inserted.
A special double-layered mesh, designed so as to be non-adherent and reduce adhesions to the underlying bowel, is inserted into the abdomen and positioned exactly over the hernial defect.
These meshes are stapled in place from within, and additional stay sutures are placed to keep them positioned over the incisional hernia defect, with the pressure exerted against the mesh from within maintaining the mesh in position.
Patients operated on laparoscopically for an incisional hernia, can usually be discharged within 24 to 36 hours of their surgery, and return to normal activity within 2 to 3 weeks.
