Endoscopic removal of a migrated stent in the gallbladder
An 84-year old man was admitted to our hospital with fever and abdominal pain. An abdominal computed tomography (CT) scan revealed evidence of acute cholecystitis ([Fig. 1]). Percutaneous transhepatic gallbladder drainage was performed and his symptoms improved; however, cholecystectomy could not be performed because the patient’s heart function was too poor.
To prevent him developing recurrent cholecystitis, we tried to perform endoscopic transpapillary gallbladder stenting [1] [2] [3], but owing to a crooked cystic duct, a bilateral pig-tail plastic stent (6 Fr, 10 cm) was placed in an incorrect position ([Fig. 2]).
We initially tried to retrieve the migrated stent using several types of basket; however, all of these attempts failed ([Fig. 3]). Finally, we tried to move the stent using a polypectomy snare, which consists of a single looped wire that can easily grip the tip of the stent ([Fig. 4]). Using this snare, we succeeded in smoothly placing the stent in the correct position ([Fig. 5] and [Fig. 6]).
Stent migration into the gallbladder is a rare but important condition for endoscopists.
