Project description:Video 1ERCP was notable for a proximally migrated biliary stent. Cholangiogram demonstrated multiple filling defects consistent with choledocholithiasis surrounding the proximally migrated biliary stent. Retrieval of the stent was successful using cholangioscopy-directed electrohydraulic lithotripsy, extracorporeal shockwave lithotripsy, mechanical lithotripsy, and minisnare over the course of 2 ERCPs. Complete duct clearance of stones was accomplished with balloon sweeps.

Removal of proximally migrated biliary stents by using single-operator cholangioscopy.

Project description:Background and aimsMigration is a late adverse event of biliary stent placement. It occurs in 1% to 20% of cases and is associated with a diverse array of adverse events. In this article, we report our take on endoscopic extraction of proximally migrated biliary stents by the use of single-operator cholangioscopy.MethodsThis report includes 3 patients who were found to have proximal stent migration while being treated for biliary stones. One patient had a migrated metal stent, and the other 2 had plastic stents. Single-operator cholangioscopy was used to retrieve the stents in all patients. The SpyBite biopsy forceps accessory was used to extract the metal stent, whereas the SpyBasket and the SpySnare were used to extract the plastic stents.ResultsAll patients underwent successful stent removal by the techniques described in this report, with no immediate adverse events, and they completed more than 4 weeks of follow-up care with no further adverse events.ConclusionsDigital single-operator cholangioscopy with SpyBasket, retrieval snare, and SpyBite biopsy forceps can be useful tools to remove migrated plastic and metallic stents, respectively.

Endoscopic Management of a Proximally Migrated Fully Covered SEMS Using the Stent-in-Stent Technique.

Project description:Endoscopic biliary decompression via stent placement is an important approach for the palliative management of distal malignant biliary obstruction. However, migration of the inserted stent can occur, either distally or proximally; proximal migration is less common, but it also presents a greater challenge for endoscopic resolution. We present a case of a 67-year-old woman who had locally advanced pancreatic cancer and developed a common bile duct obstruction. Upon clinical presentation of chronic, painless, progressive jaundice, the obstruction was managed by placing of a 10?mm?×?60?mm covered self-expandable metal stent (CSEMS), which successfully facilitated palliative biliary drainage. Six months later, however, the patient developed recurrent jaundice, which was determined to be due to proximal migration of the CSEMS. Repeat endoscopic retrograde cholangiography was performed, and initial attempts to retrieve the migrated stent failed. Finally, another 10?mm?×?60?mm CSEMS was placed across the stricture site, inside the previous stent, which remained in place. The treatment resolved the obstruction and jaundice, and the patient experienced no adverse events.
