Incisional hernia follows operations on the anterolateral abdominal wall. It is a diffuse extrusion of peritoneum and abdominal contents through a weak scar due to the failure of the lines of closure of the abdominal wall following laparotomy. The incidence of incisional hernia varies widely in different series published and is at least 10% as shown in longterm follow-up studies.
Clarification regarding the type of mesh and its positioning and operative methods of open surgery and laparoscopic repair needs to be addressed. In addition to surgical closure techniques, patient's risk factors also influence surgical outcome following wound closure.
Age, gender and risk factors such as diabetes, Hypertension, Anaemia, Obesity, COPD and Type of previous incision contribute to the development of primary and recurrent incisional hernia. Although complete prevention of development of incisional hernia is not possible, repair of hernia by replacement of simple suture technique with that of mesh reinforcement has shown better longterm results and patient satisfaction.
For management of incisional hernia, the available evidence has been favourable for good quality long term results with mesh repair techniques.
