Summary
Late-presenting Morgagni hernias in children are often diagnosed via gastrointestinal and respiratory symptoms. These congenital abnormalities are generally benign, with no mortality observed in this study.
Area of Science:
- Pediatric Surgery
- Congenital Abnormalities
- Thoracic Surgery
Background:
- Morgagni hernias are rare congenital defects.
- Late presentation is less common than early presentation.
- Understanding late-presenting Morgagni hernias is crucial for diagnosis and management.
Purpose of the Study:
- To review clinical data of infants and children with late-presenting Morgagni hernias.
- To identify common symptoms, diagnostic methods, and associated abnormalities.
- To evaluate surgical outcomes and the overall prognosis of these hernias.
Main Methods:
- Retrospective review of 15 pediatric cases of late-presenting Morgagni hernias (presentation > 8 weeks).
- Analysis of clinical presentation, diagnostic imaging (chest x-ray, barium studies), and surgical findings.
- Assessment of postoperative outcomes and associated congenital anomalies.
Main Results:
- Most patients (10/15) were asymptomatic at presentation, with gastrointestinal and respiratory symptoms being most common.
- Chest x-ray was the primary diagnostic tool, though initial assessments varied.
- Twelve patients had other major congenital abnormalities; 14 underwent surgery with no mortality.
- Hernias frequently contained hollow viscera and often had associated abnormal bowel fixation.
Conclusions:
- Late-presenting Morgagni hernias in children are relatively benign conditions.
- Early diagnosis and surgical intervention are generally successful.
- The presence of other congenital anomalies is common but does not preclude favorable outcomes.
