Case Description/
Methods: ERCP revealed a mid-common bile duct anastomotic stricture with the goal of bridging the stricture with WallFlex fully covered metal stent. However, it was mis-deployed and lodged within the common bile duct (CBD). Multiple attempts were made for stent retrieval using standard removal techniques including rat-tooth forceps, pediatric biopsy forceps, standard biopsy forceps, and retrieval basket but the attempts were unsuccessful as the CBD was diffusely dilated adding further to the difficulty of the case. This resulted in instruments passing parallel to and beyond the stent. At this point, decision was made to perform cholangioscopy for direct visualization of the CBD. A digital cholangioscope was advanced over a guidewire into the distal CBD. A SpyBite™ biopsy forceps was used to grasp the stent under direct visualization. The stent was successfully dislodged and subsequently removed from the duct with rat-tooth forceps. The patient tolerated this procedure well and no additional intra-procedural and post-procedural complications were noted upon assessing the patient in recovery area. Discussion: This case highlights the adjunct of cholangioscopy usage by advanced interventional and therapeutic gastroenterologists in managing challenging biliary stent removals when conventional techniques are unsuccessful, particularly in post-transplant patients with altered anatomy or chronic strictures.This may prevent the need for more invasive surgical interventions.
