Incisional hernias occur when the fascia of the abdominal wall does not heal well after a surgical incision. These hernias more frequently develop in the setting of obesity, coughing, straining, infection, malnutrition, steroid or chemotherapy administration, and emergency surgery.
An incisional hernia can develop any time after surgery. These hernias gradually increase in size and may become more symptomatic. The size of an incisional hernia can vary significantly. Small hernias have greater risk of organs being stuck while larger hernias can become more symptomatic as the hernia increase in size.
