Rapid evolution of a Morgagni hernia with herniation of the left hepatic lobe: case report and review of the literature.

Morgagni hernias are a rare form of congenital diaphragmatic hernia, commonly found on cross-sectional imaging. Repair is generally performed electively for pulmonary or gastrointestinal symptoms. Our case presented acutely with gastric obstruction. Two months prior she had a small bowel obstruction and underwent computed tomography, diagnostic laparoscopy, lysis of adhesions and takedown of the falciform ligament, where a 'groove' to the left of the falciform was noted, but not repaired. We collected the presentation, technique, complications and results of 12 prior cases. A trans-abdominal, robotic-assisted tissue repair of the diaphragm with mesh reinforcement utilizing as few as three ports appears to be safe and effective. The robotic platform offers additional degrees of freedom, making retrosternal operating more ergonomic to the surgeon. The rapid progression of our patient suggests that repair at the time of discovery should be considered so that the serious complications can be avoided.
