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 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:Evaluation of indeterminate biliary strictures by brush cytology and intraductal biopsies is limited by low sensitivity. The utility of SpyGlass peroral cholangioscopy for diagnosis of malignant biliary strictures and cholangiocarcinoma (CCA), in particular, remains unclear. Our aim was to study the utility of SpyGlass peroral cholangioscopy and targeted biopsy for diagnosis of malignant biliary strictures and CCA.In this systematic review, PubMed and Embase databases were reviewed for studies published to October 2014. The main outcomes of interest were sensitivity, specificity, and diagnostic odds ratio (DOR) of SpyGlass cholangioscopy in the diagnosis of malignant biliary strictures.The search yielded 10 studies involving 456 patients. The pooled sensitivity and specificity of cholangioscopy-guided biopsies in the diagnosis of malignant biliary strictures was 60.1% (95% confidence interval [CI], 54.9%-65.2%) and 98.0% (95% CI, 96.0%-99.0%), respectively. The pooled DOR to detect malignant biliary strictures was 66.4 (95% CI, 32.1-137.5). Four studies included patients who had previous negative imaging and brushings and/or intraductal biopsies. Among these 4 studies, the pooled sensitivity and specificity for diagnosis of malignant biliary strictures was 74.7% (95% CI, 63.3%-84.0%) and 93.3% (95% CI, 85.1%-97.8%), respectively. The pooled DOR was 46.0 (95% CI, 15.4-138.1). Only 1 study directly compared the yield of SpyBite biopsies with standard brushings and biopsies. SpyBite biopsies had a sensitivity of 76.5% compared with brushings (5.8%) and biopsies (29.4%). Six studies specifically reported the role of cholangioscopy with targeted biopsies in the diagnosis of CCA. The pooled sensitivity and specificity to detect CCA was 66.2% (95% CI, 59.7%-72.3%) and 97.0% (95% CI, 94.0%-99.0%), respectively. The pooled DOR to detect CCA was 79.7 (95% CI, 32.7-194.7).Our study suggests that SpyGlass cholangioscopy with SpyBite biopsies has moderate sensitivity for the diagnosis of malignant biliary strictures.

Project description:BackgroundWith improving and aggressive endovascular venous and dialysis techniques there is increasing use of stent grafts with different platforms available on the market. Inappropriately sized stents may displace and potentially end up in the heart or lungs as potential dangerous foreign bodies. There is single published case of successful viabahn stent graft retrieval from the pulmonary circulation.Case presentationWe present a patient who had successful safe percutaneous retrieval of a migrated Viabahn stent from a segmental Pulmonary artery and describe a different novel safe technique of successful stent graft retrieval from the pulmonary artery with very low risk to potential damage to the cardiac valve complex.ConclusionThis case report demonstrates that Viabahn stent grafts can be safely retrieved from the pulmonary arterial system using this endovascular technique that will significantly reduce the risk of damage to the cardiac valve complex therefore avoiding potential complex surgery.

Project description:IntroductionMirizzi syndrome is an infrequent complication of long-standing cholelithiasis. Extrinsic compression of the common hepatic duct is usually caused by an impacted stone in Hartmann's pouch or cystic duct resulting in the development of cholecystobiliary fistula. This syndrome is classified based on the presence and severity of cholecystobiliary fistula. Mirizzi syndrome is challenging to diagnose preoperatively and may require complex biliary surgical procedures for resolution.ResultsWe present three patients with Mirizzi syndrome with different clinical presentations. All were successfully treated by cholangioscopy with electrohydraulic lithotripsy. Endoscopic treatment is a safe alternative with a high success rate. Single-operator cholangioscopy combined with lithotripsy has been shown to have a 90-100% success rate in the treatment of biliary stones.ConclusionHerein, we present our experience treating Mirizzi syndrome with single-operator cholangioscopy guided electrohydraulic lithotripsy. Difficult management of Mirizzi syndrome has led to research of new treatment options to minimize the risk of high-rate complications. Single-operator cholangioscopy in combination with laser lithotripsy is an adequate and safe alternative for the treatment of this condition.
