Obstructive jaundice is an uncommon cause of jaundice in children past the neonatal period. Operation on these patients carries some risks. We present a patient with Down's syndrome who developed jaundice, which resulted from recurrent Morgagni's diaphragmatic hernia causing displacement of the second part of the duodenum and obstruction of the common bile duct. We discuss the management and risks involved in these patients. We believe that obstructive jaundice due to Morgagni's diaphragmatic hernia has not been reported before.
