Clinical determinants of mortality in congenital diaphragmatic hernia: a single-center cohort study from Colombia.

Prenatal diagnosis was established in 74.7% of cases, and 68.1% of patients achieved sufficient stabilization to undergo surgical repair.

Non-survivors had higher rates of perinatal asphyxia and lower birth weight and gestational age.

Patients undergoing surgical repair showed significantly better initial oxygenation and gas exchange parameters.

Among surgically treated patients, mortality was associated with non-primary repair, larger defect size, absence of hernia sac, delayed abdominal closure, and postoperative complications.
