Diaphragmatic eventration in children.

BACKGROUND: Diaphragmatic eventration (ED) is a rare anomaly defined by a permanent elevation of a hemidiaphragm without defects. Clinical manifestations are diverse, ranging from asymptomatic to life-threatening respiratory distress. The aim of this study is to report our experience of management of eight children with ED over the past 15 years.

METHODS: A retrospective study was conducted involving 8 infants and children with ED managed at the department of pediatric surgery of Tunis Children's Hospital.

RESULTS: Five patients (2 males, 3 females) whose ages ranged from 5 month to 7 years (mean, 13 months) were operated on using diaphragmatic plication (3 right-sided and 2 left-sided plications) for symptomatic ED with a dramatic improvement in their respiratory status. Another infant (a 3-month-old boy) was admitted for respiratory distress that required mechanical ventilatory support. He died before operation because of sepsis. Two other asymptomatic patients with incidentally diagnosed ED were followed up for 5 years on average. Chest x-ray suggested eventration in all cases. Ultrasound was found to be a useful modality for diagnosis in 6 cases. There were no cases of associated malformation.

CONCLUSION: Diaphragmatic eventration in children is usually congenital but may be acquired. Chest ultrasound is an important imaging modality for diagnosis. Diaphragmatic plication appears to be safe and effective. Surgical intervention is not recommended in asymptomatic patients.
