Laser therapy for ablation of an embedded biliary metalic stent
Poster Abstract

Abstract Text

Embedded stents in gastrointestinal tract can be challenging to remove. When standard methods such as traction, compression necrosis or radiofrequency ablation fail, surgery maybe needed. Our case is of a 25-year-old man who presented with a  common hepatic duct stricture following cholecystectomy for cholelithiasis. He underwent placement of a fully covered metal stent via percutaneous transhepatic biliary drainage (PTBD). Stent removal with standard methods with traction and radiofrequency ablation was unsuccessful. Patient declined surgery. ERC with Cholangioscopy was performed which showed stent embedded in the bile duct wall. Cholangioscopy guided laser ablation (30 watts for 40 minutes) was performed to ablate the tissue overgrowth and fragment the embedded portion of the stent. Ultimately the stent could be removed succesfully.
