Rectus sheath hernia
Updates to Article Attributes
A rectus sheath hernias (alternative plural: herniae) are a rare type of anterior abdominal wall hernia where there is herniation of intra-abdominal content (mesenteric fat +/- bowel) usually through the posterior rectus sheath and therefore often termed a posterior rectus sheath hernia. The hernia can extend to various degrees.
These hernias are considered interparietal due to the herniating sac lying between the layers of the abdominal wall. The majority of these hernias are considered post-surgical or post-traumatic in aetiology, with occasional spontaneous cases being reported in the literature
