Background:Morgagni diaphragmatic hernia is a rare congenital hernia that lies retrosternal through a congenital defect between the sternal and costal portions of the diaphragm. Surgical repair of Morgagni hernia is recommended because incarceration or strangulation of bowel within the thoracic cavity may occur. Methods: A case of Morgagni diaphragmatic hernia is presented and laparoscopic repair using Gore-Tex DualMesh is described. Results: There was complete resolution of the patient's symptoms including her dyspnoea. There were no postoperative complications. Conclusion: Laparoscopic repair of Morgagni diaphragmatic hernia is a safe and effective method for treating this rare surgical condition. The use of dual-layer mesh allows tension-free repair without the risk of intraabdominal adhesions forming between bowel and mesh.
