A Biliary Stent in the Gallbladder Lumen: Misplacement or Migration?

Abstract

This case report describes a patient who presented with cholangitis gallbladder sludge, choledocolithiasis, and biliary dilatation. The patient’s magnetic resonance cholangiopancreatography demonstrated that the cystic duct had low and medial insertion on common bile duct. However, the patient presented with abdominal discomfort after the completion of an endoscopic retrograde cholangiopancreatography stenting. Subsequent imaging revealed the proximal stent lying in the gallbladder lumen. The case highlights the importance of having the endoscopists recheck and confirm the positioning of the stent, post-procedure. In addition, it is important to raise awareness among physicians/gastroenterologists regarding the possibility of presence of biliary stent in gallbladder lumen, especially in those patients with a history of endoscopic biliary intervention(s).
