A 70\u2010year\u2010old man had undergone multiple operations, including a living donor liver transplantation (<jats:styled-content style=\"fixed-case\">LDLT<\/jats:styled-content>) and hepaticojejunostomy.

A radiographic contrast study and computed tomographic scan indicated a movable mass as the cause of the ileus, suggesting a giant stone. We were unable to observe or remove the stone by double balloon enteroscopy owing to the presence of severe adhesion; thus, we surgically removed the mass.
