What Are Incisional Hernias?

Frequency Of Occurrence

An incisional hernia's frequency is based on numerous factors. Studies have proven all major abdominal surgical procedures carry a thirty-three percent risk of an incisional hernia post-operation. It is estimated that less than one-fifth of all hernias that occur in the abdominal region are considered incisional hernias. The highest occurrence of incisional hernia happens with a midline type of incision at seventy-four percent, where it is less common with transverse and paramedian incisions. Horizontal incisions are less likely to result in an abdominal hernia than vertical incisions. Incisions in the upper abdominal region are more likely to cause an incisional hernia than those in the lower abdominal area. Individuals who have a body mass index of over twenty-five are more likely to experience an incisional hernia. An infected surgical wound that is healing is sixty-eight percent more likely to result in an incisional hernia. Other factors that make an individual more susceptible to experiencing an incisional hernia are an intra-operative blood transfusion, pre-operative chemotherapy, being elderly or of advanced age, and pregnancy.
