Extensive small bowel necrosis due to congenital para duodenal hernia: A diagnostic and therapeutic challenge: Case Report.

Introduction: A paraduodenal hernia is a rare variety of hernia, however it is the most usual type of internal hernias. Clinical presentation is nonspecific. The clinical presentation is variable: indeed, the patient can be completely asymptomatic or present with symptoms which severity is variable according to the mechanism. The most common cause is an acute intestinal occlusion that could progress even to ischemia and intestinal necrosis. Depending on the clinical presentation and the suspected diagnosis, computed tomography can be of considerable help in demonstrating a para duodenal hernia.

Case Presentation: We describe the case of a young man aged 18 years, who presented to the emergency unit with severe abdominal pain associated with incoercible vomiting. The surgical exploration had confirmed a para duodenal hernia responsible for an extensive necrosis of the small intestine allowing viable 90 cm only.

Case Discussion: Paraduodenal hernias are rare and their diagnosis is not always easy. Therefore, they should be considered especially in the case of an occlusive syndrome occurring in a young patient who has never been operated on. If no treatment is undertaken, the evolution is drastic and the mortality rate is significant.

Conclusion: Successful surgical management requires knowledge of the intra-abdominal peritoneal spaces and management of suggestive clinical situations in order to reduce postoperative morbidity and mortality resulting from delayed diagnosis and treatment.
