Acquired Diaphragmatic Hernia Following Pediatric Liver Transplantation: Incidence, Risk Factors, and Surgical Outcomes

Topic overview

Key takeaways

• Acquired diaphragmatic hernia occurs in 3.3% of pediatric liver transplant recipients, predominantly in infants under 1 year and those weighing <8 kg
• Risk factors include younger age at transplant, low body weight, prior abdominal surgery, and left lateral segment grafts
• Most hernias are right-sided with variable presentation from respiratory symptoms to incidental findings on imaging
• Thoracoscopic repair is feasible in selected patients with favorable short-term outcomes comparable to open laparotomy
• Standardized screening protocols and predictive models are needed to identify high-risk patients for early detection
