title: Obstructive jaundice caused by biliary stone formation around the stent after liver transplantation.
abstract: We report an unusual case of obstructive jaundice caused by a biliary stone, which developed in the stump of a Roux-en-Y hepaticojejunostomy after undergoing LT. The patient was a 13-yr-old male. At 74 days after birth, a hepaticojejunostomy (Kasai's procedure) was performed for the treatment of biliary atresia. He underwent a reduced size deceased donor LT in the left subphrenic space twice at the age of one and three years in Australia. Eleven years after his second LT, he developed liver dysfunction and jaundice with a low grade fever. Computed tomography showed a marked jejunal loop enlargement by a rugby ball-shaped stone and the bile duct in the graft was thus dilated. A surgical exploration revealed the jejunal loop to be bent sharply while its stump side was dilated by stagnated bile including a biliary stone. The stone included a stent that had been previously used for the hepaticojejunostomy. This case suggests that a retained stent used for hepaticojejunostomy had thus caused biliary stone formation because of a combination of various conditions in the jejunal loop.
