Cholangioscopy-guided retrieval basket and snare for the removal of biliary stones and retained prostheses.

ABSTRACT:

Background and aims

Certain 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.

Methods

Three cases using the SpyGlass retrieval basket and retrieval snare were reviewed for efficacy.

Results

Patient 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.

Conclusions

This 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: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.
