Incisional hernia

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.
