A CASE OF ENDOSCOPIC RETRIEVAL OF A MIGRATED BILIARY STENT TUBE DAMAGED BY EXFOLIATION OF THE FLAPS

Abstract

A 67-year-old man had been under treatment with placement of a biliary tube stent for a bile duct stricture associated with chronic pancreatitis. He suffered from high fever at 17 months after the stenting. He was admitted to our hospital for evaluation and treatment. He was diagnosed with cholangitis and stent tube migration caused by exfoliation of the flaps. Although insertion of the guidewire into the stent was difficult, we successfully managed to recover the stent by endoscopic procedure. Exfoliation of the flaps was thought to result from brittle fracture by quality deterioration. Care must be taken that a biliary stent tube may migrate by exfoliation of the flaps, particularly during its long-term placement.
