A rare case of acute abdomen due to strangulated Waldayer's hernia

An internal hernia is the herniation of an intestinal segment into an intra-peritoneal fossa, is an uncommon cause for intestinal obstruction and is difficult to diagnose preoperatively.

We report a male patient 19 years old presenting with acute abdomen due to a strangulated Waldayer's hernia.

The paraduodenal hernias are more common in males (M:F ratio 3:1). The average age at diagnosis is 38.5 years clinically presenting with chronic intermittent post-parandial abdominal pain. An accurate incidence of paraduodenal hernias in infancy and childhood is unknown, but is quite rare.

Internal complicated hernias are difficult to diagnose and once discovered intra-operative anatomical variations are present with special attribution to the management of the hernia sac.
