HOW COMMON ARE THEY?
An Incisional Hernia is a hernia that occurs through a previously made incision in the abdominal wall, ie the scar left from a previous surgical operation.The incision will have been made in order to get to an internal organ such as the appendix, or a caesarian section.
ARE INCISIONAL HERNIAS DANGEROUS?
As with all hernias, if the hernia strangulates, i.e. the hernia contents (the intestine) get trapped and lose their blood supply, which is very dangerous.
