A patient with a swelling of the abdominal wall is a regular occurrence in general practice and hospital. The diagnosis can often be made with a thorough history and physical examination. An abdominal wall hernia is characterized by an increase in swelling on standing physical examination and Valsalva maneuver, which is often reducible, and a hernia defect is palpable. If no interruption of the abdominal wall is palpable and there is hypoesthesia, there may be an abdominal wall paresis because of thoracic paramedian hernia nuclei pulposi (HNP). Where an abdominal wall hernia is treated surgically in case of symptoms, this is conservatively treated with an HNP.
