Congenital Left Mesenteric-Parietal Hernia Associated to a Small Bowel Volvulus: About a Case

Introduction: The left mesenterico-parietal hernia or left paraduodenal hernia is an anomaly of intestinal rotation which may be responsible for intestinal obstruction. It is rare. Observation: A 5-year-old boy was admitted for abdominal pain with episodes of vomiting and cessation of matters and gases. After clinical and paraclinical investigations, the diagnosis of occlusion was accepted and the child was operated. Exploration revealed a mesenterico-parietal hernia with a retrocolic sac measuring 11 cm of collar and a deep of 18 cm containing a twisted bowel. After reduction of the content, we untwisted the small intestine and released adhesions. The hernial sac was partially resected and the defect was closed. Operating outcomes were simple. Conclusion: The mesenterico-parietal hernia is a cause of organic intestinal obstruction. Although of congenital origin, it can have a late clinical manifestation. It should be considered in case of episodes of repetitive abdominal pain and vomiting to avoid complications.
