Laparoscopic double mesh repair of a large Morgagni hernia: a video vignette.

Morgagni hernia (MH) is a rare congenital diaphragmatic hernia (CDH) that accounts for less than 2% of surgically repaired CDH in adulthood. Even if this condition is often asymptomatic, surgery is advised due to the risk of life-threatening complications such as volvulus or bowel strangulation. Surgery for MH repair can be performed by transthoracic, transabdominal, laparoscopic, or thoracoscopic approaches. Though laparoscopy has recently improved surgical outcomes, the use of prosthetic meshes and the need for reduction of the hernia sac are still the most debated issues. We present the video of a laparoscopic repair of a large MH with the use of a double mesh technique and no resection of the hernia sac.
