Incisional hernia

Dr Varun Babu and A.Prof Frank Gaillard et al.

Incisional hernias are relatively common and along with parastomal herniasumbilical herniasparaumbilical hernias and spigelian hernias, they are usually anterior abdominal hernias.

Usually develop within a few months of surgery but a small proportion can remain clinically silent for years. They typically occur after laparotomy with rates of ~7.5%. 

Incisional hernias occur most frequently through previous laparotomy scars (other incisional hernias are possible, such a lung hernia). Widening or dehiscence of the scar allows intra-abdominal content to herniate into the subcutaneous tissues.

Complications are similar to other hernias, and include incarceration, strangulation and intestinal obstruction.
