While rare, the management of patients with a Morgagni diaphragmatic hernia can be challenging. Traditional methods utilizing laparoscopy describe primary fascial defect closure and the placement of permanent synthetic mesh in the sublay position (intraabdominally) mandating the use of an expensive barrier coated mesh and requiring penetrating fixation along the diaphragm. Still, others have described a thoracic approach, often requiring a thoracotomy with a subsequent extended postoperative hospital stay and increased patient pain. In an effort to keep the mesh outside of the abdomen, we describe the novel extraperitoneal placement of mesh in a patient who presented to our clinic with complaints of shortness of breath. Preoperative computed tomography showed a large Morgagni hernia with incarcerated omental fat in the thoracic cavity. While it was unclear that all of her symptoms were attributed to her Morgagni hernia, extensive preoperative pulmonary and cardiac workup was otherwise unremarkable. Therefore, we performed a robotic-assisted laparoscopic extraperitoneal repair of an incarcerated Morgagni hernia utilizing a 15x13cm uncoated heavy-weight polypropylene permanent synthetic mesh to cover the bi-lobed 7x4cm diaphragmatic defect. The patient had an uncomplicated postoperative course and was discharged on post-operative day one and subjectively, her shortness of breath greatly improved. The extraperitoneal repair offers several key advantages: The use of uncoated mesh greatly reduces total operative costs, the placement of mesh outside of the abdomen decreases future intraperitoneal adhesions, and the extraperitoneal repair can be combined with a minimally invasive approach to shorten length of stay and reduce patient postoperative pain.
