Laparoscopic mesh repair of parahiatal hernia: A case report

We report a case of a primary parahiatal hernia that was repaired laparoscopically with a composite mesh. A 51‐year‐old woman presented with vomiting and epigastric pain. CT scan showed a giant paraesophageal hernia with intrathoracic gastric volvulus. Intraoperatively, a diaphragmatic muscular defect was found lateral to an attenuated left crus of the diaphragm, distinct from the normal esophageal hiatus. The defect ring was fibrotic, making a tension‐free primary repair difficult. A laparoscopic mesh repair was performed with a composite mesh, which was covered with the hernia sac to prevent potential erosion into the esophagus or stomach. Recovery was uneventful and the patient was discharged on the 5 days postoperatively. She remained asymptomatic at subsequent follow‐up. Laparoscopic repair of parahiatal hernia can be safely performed. In circumstances where a large or fibrotic defect prevents a tension‐free primary repair, the use of a composite mesh can provide effective repair of the hernia.
