Diaphragmatic hernia in infants following living donor liver transplantation: report of three cases and a review of the literature.

DH is a rare complication following LT. This report presents three cases of right-sided DH after LT using a left-sided graft. All of the patients were younger than one yr of age, and they were critically ill owing to their original disease, characterized by biliary atresia, progressive familiar intrahepatic cholestasis, and acute liver failure. DH occurred with sudden onset within three months after LT. All of the cases were promptly diagnosed and treated. A literature review of 24 cases of DH identified four factors associated with DH: left-sided graft, right-sided DH, relatively delayed onset of DH, and age-specific chief complaint. DH following LT should be considered as a potential surgical complication when a left-sided graft is used, especially in small infants with coagulopathy and malnutrition.
