The intra-abdominal zebra, paraduodenal hernias resulting in small bowel obstructions: a case series

Paraduodenal hernias are a rare but important clinical entity, as their presentation can be life-threatening if not properly diagnosed and managed appropriately. Additionally, this entity is defined by a unique and complex congenital anatomical abnormality which dictates a specific treatment algorithm. Here we present the cases of three patients from our clinical experience who all presented with either acute or chronic small bowel obstructions secondary to paraduodenal hernias. Two were left-sided paraduoenal hernias and one was right-sided. All three patients were successfully managed with surgical intervention. An appreciation of paraduodenal hernias, including the defining anatomy and methods of surgical management, is important for the general surgeon.
