Jean-Louis Petit primary lumbar hernia in a 70-year-old man in Burkina Faso: a case report

Introduction: Jean-Louis Petit (JLP) hernia is a rare form of lumbar hernia occurring through the inferior lumbar triangle and accounts for approximately 5% of lumbar hernias. Due to its rarity, diagnosis may be delayed or confused with other lumbar masses. Case presentation: We report the case of a 70-year-old male farmer presenting with a right lumbar swelling that had been evolving for 2 years with intermittent pain. Clinical examination revealed a 17-cm reducible mass. Computed tomography (CT) confirmed a JLP hernia containing digestive loops. Open surgical repair was performed. Intraoperatively, the cecum and appendix were found to be adherent to the hernia sac. Adhesiolysis resulted in two cecal perforations, which were immediately repaired. Postoperative evolution was uneventful. Discussion: JLP hernia is an uncommon condition that may be congenital or acquired. A CT scan plays a crucial role in diagnosis. Surgical repair is recommended due to the risk of strangulation. Long-standing hernias may develop dense adhesions, increasing the risk of intraoperative complications. Conclusion: Early diagnosis and meticulous surgical management are essential to prevent complications and ensure favorable outcomes.
