Laparoscopic repair of Morgagni hernia

Foramen of Morgagni hernias are rare diaphragmatic hernias. They account for 3-5% of all diaphragmatic hernias and the majority of the cases are asymptomatic. They are caused by trauma, obesity or pregnancy. With the advancements of laparoscopic surgery, laparoscopic repair has become an excellent alternative to open repair for Morgagni hernias. We report five cases of Morgagni hernia repaired with the laparoscopic approach in conjunction with a review of the literature. A retrospective review comprised five patients who had a Morgagni hernia repaired with a laparoscopic approach. Data from these patients were collected for the period between February 2001 and May 2005. The average age at operation was 61. The anatomic pathology was detected preoperatively using X-rays and computerized tomography (CT) scans in four of our patients. Hernia was detected incidentally in one patient during an elective cholecysectomy. Three hernias were right-sided and two were left-sided. The contents of the hernias were omentum and transverse colon in the majority of the patients. The hernia was repaired with a laparoscopic approach in all patients. Four patients had composite mesh repair and one patient had primary closure with nonabsorbable sutures. There were no postoperative complications and all patients tolerated laparoscopic repair. There were also no recurrences during follow-up. Laparoscopic repair is a candidate to be a standard treatment for Morgagni-type hernias. It is an effective and safe technique and can be performed by all compotent general surgeons with a certain learning curve. It has several advantages relative to the open operation.
