Extra-abdominal hernias are most often caused by reduced strength of the abdominal wall and increased pressure in the abdominal cavity, including both congenital and acquired causes. Congenital factors such as unclosed peritoneal sheaths and underdeveloped abdominal white lines are mainly seen in children. Acquired causes include recurrent coughing and phlegm, having benign prostatic hyperplasia, difficulty urinating, or habitual constipation, which can easily lead to a sustained or transient increase in intra-abdominal pressure and consequently to an extra-abdominal hernia. In addition, infection of the incision after abdominal surgery can also lead to the development of an extra-abdominal hernia.
