Abstract
Adult bilateral retrosternal hernia is very rare. A 87-year-old woman seen for repeated nausea, vomiting, and epigastralgia was found in computed tomography (CT) to have a bilateral retrosternal hernia prolapsed with the stomach the right hernia sac and the transverse colon the left. Laparoscopic surgery recognized two hernia sacs in the anterior aspect of the diaphragm, but with the transverse colon herniated into the right hernia sac, unlike on CT. The herniated transverse colon was easily placed into the abdominal cavity and Composix mesh placed over the bilateral hernia hilum without hernia sac resection. Postoperative recovery was uneventful and the woman has remained free of recurrence and complications in the 10 months since surgery.
