Right-sided paraduodenal hernia with malrotation - A case report

Introduction: Paraduodenal hernia is a rare cause of internal hernia. It is the herniation of small bowel through a peritoneal sac in the duodenum. It occurs due to incomplete rotation and fixation abnormalities of the primitive midgut during fetal development. We report a case of right sided paraduodenal hernia in an adult male. Case presentation: This is a case of 36-year-old gentleman who presented with complaints of abdominal fullness and upper abdominal pain for 1.5 months and 7 to 8 episodes of vomiting. CT scan of abdomen gave an impression of right-sided paraduodenal hernia. Exploratory laparotomy with hernia repair was performed and patient was discharged without complications. Discussion: Right sided paraduodenal hernia is the protrusion of viscera through the fossa of Waldeyer. It is frequently associated with malrotation and strangulation. Its diagnosis is frequently delayed. Symptoms are nonspecific and may need laparotomy for diagnosis. Technique of choice for surgical management remains inconclusive. Conclusion: Paraduodenal hernias are frequently diagnosed late or incidentally because of vague symptoms. They are rarer and carry higher lifetime risk of strangulation and bowel obstruction. Surgical management is necessary after diagnosis.
