Laparoscopic mesh repair of a Morgagni hernia using the double-crown technique: A case study.

We report a case of Morgagni hernia in which the patient underwent laparoscopic mesh repair. A 65-year-old woman presented with an abnormal shadow in the right lower lung field on a routine medical checkup. CT showed that the transverse colon passed between the liver and abdominal wall, and herniated into the thoracic cavity. Simple closure was precluded by the large hernial orifice. We therefore performed laparoscopic repair using a Parietex Optimized Composite Mesh. The double-crown technique was used to fix the margin of the mesh to the region around the hernial orifice. Our procedure for repair of a Morgagni hernia with a large hernial orifice is safe and minimally invasive, and it may effectively prevent recurrence.
