Procedures - Herniae
Once a hernia has occurred it will generally
enlarge gradually. It represents a mechanical defect in the
abdominal wall and will not heal itself. Most surgeons will
recommend repair of the hernia unless there is a particular
contraindication that makes it too risky. The main risk with
a hernia is if the contents of the hernia become incarcerated.
The pressure within the hernia increases and this can compromise
the blood supply. If there is bowel within the hernia this
is a life threatening situation if left untreated.
Surgical repair of the hernia involves
identifying the margins of the hernia and reducing the contents
of the hernia back into the abdominal cavity. The defect has
to then be repaired and this is usually achieved using sutures
and a prosthetic mesh to reinforce the area. There are many
variations in technique and different types of mesh that can
be used. The best method will depend on the site and size
of the hernia. It will also depend on patient characteristics.
