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

ABSTRACT: 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: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.
