A Spigelian hernia is a rare type of abdominal wall hernia that develops below the naval, more often on the right side of the abdomen. Spigelian hernias can be difficult to diagnose. Symptoms can vary and depend on the size of the hernia and contents within the hernia sac.
Congenital hernia Contributor(s): Rachel Burrow, Jacqueline Davidson. Introduction; Pathogenesis; Diagnosis; Treatment; Prevention; Outcomes; Introduction. A congenital hernia is a defect in the abdominal wall or diaphragm that is present at birth. Abdominal organs or other abdominal tissue may displace through the defect. A true hernia has a hernia sac (peritoneum) surrounding the contents. A true hernia is usually the result of a congenital weakness in the abdominal wall. True hernias are often reducible (ie contents can move freely between hernia sac and abdomen), because the hernia sac reduces adhesion formation. A false hernia has no hernia sac and is usually acquired from trauma or previous surgery.
