Laparoscopic no-mesh repair of a large Morgagni-Larrey hernia

Morgagni-Larrey hernia is a rare condition, often presenting with nonspecific symptoms or remaining asymptomatic. Surgical intervention is the primary treatment modality, typically performed via trans-abdominal access, with an increasing trend towards employing minimally invasive techniques. Herein, we report a case detailing the successful laparoscopic repair of a large Morgagni-Larrey hernia without the use of mesh. The patient, a 55-year-old male, presented with chest pain following blunt thoraco-abdominal trauma. Chest radiographs and 3D-CT scan revealed a dense mass in the precordial space, initially suspected to be a diaphragmatic rupture. The diaphragmatic defect which was repaired laparoscopically, appeared to be a large Morgagni-Larrey hernia rather than a rupture. At the two-year follow-up, a repeat 3D-CT and laparoscopy were conducted to assess the previous repair and address a port site (drain site) hernia. No intra- or postoperative complications were encountered. Our experience supports the safety and efficacy of the laparoscopic no-mesh technique for repairing large Morgagni-Larrey hernias.
