Abstract

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.
