Congenital Morgagni's hernia: a national multicenter study

Area of Science:

• Pediatric Surgery
• Surgical Outcomes
• Congenital Abnormalities

Background:

• Congenital Morgagni's hernia (CMH) is a rare condition, accounting for less than 5% of all congenital diaphragmatic hernias.
• This study reviews national experience with CMH, focusing on presentation, diagnosis, associated anomalies, treatment, and outcomes.

Purpose of the Study:

• To outline the clinical presentation, diagnostic methods, associated anomalies, treatment strategies, and outcomes for Congenital Morgagni's hernia.
• To evaluate the effectiveness of different surgical approaches for CMH repair.

Main Methods:

• Retrospective review of medical records for 53 pediatric patients diagnosed with CMH over a 20-year period (1990-2010).
• Data collected included age at diagnosis, sex, symptoms, associated anomalies, operative findings, treatment approach (open vs. minimally invasive), and patient outcomes.
• Surgical approaches analyzed included open repair, laparoscopic-assisted repair, and totally laparoscopic repair.

Main Results:

• The majority of patients (81%) presented with recurrent chest infections.
• Associated anomalies were frequent (71.7%), including congenital heart disease (39.6%) and Down syndrome (28.3%).
• Laparoscopic-assisted repair demonstrated advantages over open repair, including shorter operative time, earlier feeding, less analgesia, shorter hospital stay, and better cosmetic results, with no mortality.

Conclusions:

• Congenital Morgagni's hernia in pediatric patients commonly presents with recurrent chest infections and frequently co-occurs with congenital heart disease and Down syndrome.
• A laparoscopic-assisted approach is recommended for CMH repair due to its efficiency, safety, and superior patient outcomes compared to open surgery.
