Incisional hernias occur when there is bulging of an organ or tissue through a previous surgical scar/incision. These can occur anywhere on the abdomen.
Whenever you undergo surgery, there is a weakness in the muscle layers where the incision is made. When these incisions do not heal properly for one reason or another, they can allow the protrusion of a hernia through the old scar/incision leading to the incisional hernia. Certain conditions can affect wound healing including diabetes mellitus, smoking, obesity as well as some medical conditions. It is important that you inform Total Upper GI Surgery of these conditions so they can be optimised before considering surgery.
