Project description:Background and Aims:Migration 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. Methods:This 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. Results:All 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. Conclusions:Digital single-operator cholangioscopy with SpyBasket, retrieval snare, and SpyBite biopsy forceps can be useful tools to remove migrated plastic and metallic stents, respectively.

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.

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.

Project description:Background and aimsCertain pancreaticobiliary conditions remain challenging to treat using standard endoscopic techniques. Examples include difficult-to-remove gallstones and foreign objects in the bile ducts. Two tools designed for these purposes are the SpyGlass retrieval basket and the SpyGlass retrieval snare, which are passed through the cholangioscope channel for use under direct visualization. We present 3 cases in which these tools were used successfully.MethodsThree cases using the SpyGlass retrieval basket and retrieval snare were reviewed for efficacy.ResultsPatient 1 had hepatitis C cirrhosis and underwent liver transplantation with T tube placement at the site of biliary anastomosis. Image-guided T tube removal by interventional radiology was unsuccessful. Endoscopic removal with the SpyGlass retrieval snare was completed. Patient 2 presented with cholangitis from an impacted common bile duct stone. Fragmentation with electrohydraulic lithotripsy was performed, and the fragments were removed with the SpyGlass retrieval basket. Patient 3 presented for removal of a migrated biliary stent. The stent was placed a year prior during an ERCP for treatment of choledocholithiasis. Initial removal attempt at an area hospital failed, so the patient was referred to our center, where the Spyglass retrieval snare was used to remove the biliary stent.ConclusionsThis case series demonstrates initial successes treating biliary pathologic conditions with the SpyGlass retrieval basket and retrieval snare, 2 tools designed for use under direct visualization with the cholangioscope.

Project description:Video 1Details regarding the patient's clinical presentation and prior endoscopic treatments for common hepatic duct stricture are first described in the video. Next, the video features footage from subsequent ERCP demonstrating the common hepatic duct stricture both fluoroscopically and endoscopically via cholangioscopy, followed by treatment with thulium laser stricturoplasty/dissection. The immediate post-treatment images of the stricture are displayed which demonstrated marked improvement in the stricture. Finally, the patient's ensuing clinical course is displayed in which the stricture recurred and was retreated with laser stricturoplasty/dissection and stent upsizing.

Project description:Stenting of hepatic veins can be a long lasting solution for Budd-Chiari syndrome. These stents could very rarely migrate into the right atrium. During surgical retrieval, cardiopulmonary bypass (CPB) can be avoided if vena caval inflow occlusion (VCIO) is used. A hybrid alternative of VCIO by using a balloon to occlude the inferior vena cava was done to retrieve the stent thus avoiding CPB and total circulatory arrest.

Project description:Background and aimsEndoscopic retrograde cholangiopancreatography is the preferred strategy for the management of biliary and pancreatic duct stones. However, difficult stones occur, and electrohydraulic (EHL) and laser lithotripsy (LL) have emerged as treatment modalities for ductal clearance. Recently, single-operator cholangioscopy was introduced, permitting the routine use of these techniques. We aimed to evaluate the clinical effectiveness of cholangioscopy-guided lithotripsy using LL or EHL in patients with difficult biliary or pancreatic stones.MethodsThis is a prospective clinical study - conducted at two affiliated university hospitals - of 17 consecutive patients with difficult biliary and pancreatic stones who underwent single-operator cholangioscopy-guided lithotripsy using two techniques: holmium laser lithotripsy (HL) or bipolar EHL. We analyzed complete ductal clearance as well as the impact of the location and number of stones on clinical success and evaluated the efficacy of the two techniques used for cholangioscopy-guided lithotripsy and procedural complications.ResultsTwelve patients (70.6%) had stones in the common bile duct/common hepatic duct, 2 patients (17.6%) had a stone in the cystic stump, and 3 patients (17.6%) had stones in the pancreas. Sixteen patients (94.1%) were successfully managed in 1 session, and 1 patient (5.9%) achieved ductal clearance after 3 sessions including EHL, LL, and mechanical lithotripsy. Eleven patients were successfully submitted to HL in 1 session using a single laser fiber. Six patients were treated with EHL: 4 patients achieved ductal clearance in 1 session with a single fiber, 1 patient obtained successful fragmentation in 1 session using two fibers, and 1 patient did not achieve ductal clearance after using two fibers and was successfully treated with a single laser fiber in a subsequent session. Complications were mild and were encountered in 6/17 patients (35.2%), including fever (n = 3), pain (n = 1), and mild pancreatitis (n = 1). Conclusions: Cholangioscopy-guided lithotripsy using LL or EHL in patients with difficult biliary or pancreatic stones is highly effective with transient and minimal complications. There is a clear need to further compare EHL and HL in order to assess their role in the success of cholangioscopy-guided lithotripsy.

Project description:Background and Aims:Lumen-apposing metal stents (LAMSs) play an increasing role in transgastric and transduodenal drainage of pancreatic fluid collections and allow novel EUS-guided interventions. Alongside the main adverse events of bleeding and occlusion, LAMSs can be overgrown by mucosa, which leads to the inability to visualize the stent in endoscopy. Methods:We describe a series of 4 cases of buried LAMSs that were removed under EUS guidance for identification of the stent followed by removal with rat-tooth forceps. Results:The median in situ time of the LAMSs in the reported 4 cases was 53 days. All stents could no longer be visualized endoscopically when drainage of necrosis was complete. All 4 buried LAMSs could be identified by EUS and were removed successfully with forceps. In 1 case, balloon dilation of the stent tract was performed before stent removal. No adverse events were observed after the procedure. Conclusions:Buried stent syndrome is a rare adverse event of LAMSs. Here we describe a safe and effective approach for stent identification and removal without prior mucosal dissection.
