Internal hernias occur when there is protrusion of an internal organ into a retroperitoneal fossa or a foramen (congenital or acquired) in the abdominal cavity. If a loop of bowel passes through the mesenteric defect, that loop is at risk for incarceration , strangulation , or for becoming the lead point of a small bowel obstruction . [ 1 ]
It is more often seen in men, and predominantly on the right side. Maydl's hernia should be suspected in patients with large incarcerated herniae and in patients with evidence of intra-abdominal strangulation or peritonitis. Postural or manual reduction of the hernia is contra-indicated as it may result in non-viable bowel being missed. [2]
An indirect hernia is situated laterally to these vessels, whereas a direct hernia is positioned medially to them. Inguinal hernias are the most common type of hernia in both men and women.

Amyand's hernia is a rare form of an inguinal hernia (less than 1% of inguinal hernias) [2] which occurs when the appendix is included in the hernial sac and becomes incarcerated. The condition is an eponymous disease named after a French surgeon , Claudius Amyand (1660–1740), [ 3 ] who performed the first successful appendectomy in 1735.
