Background/study aims Laser lithotripsy can effectively fragment complicated biliary stones, but current cholangioscopes are limited by fragility, restricted mobility or moderate visual resolution. The efficacy and safety of a new digital single-operator peroral cholangioscope to guide laser lithotripsy were evaluated. Patients and methods In this prospective single-center series, consecutive patients with complicated biliary stones, defined as impacted stones > 1.5 cm in size and wider than the more distal common bile duct, or stones that failed extraction by basket mechanical lithotripsy, underwent ERCP and SpyGlass DS peroral cholangioscope (Boston Scientific, Marlborough, United States)-guided laser lithotripsy...

OBJECTIVE: Painful chronic pancreatitis is often associated with main duct obstruction due to stones. Approaches to management are challenging, including surgery, extracorporeal shock wave lithotripsy, or endoscopic approaches. Here, we report our experience of pancreatoscopy + electrohydraulic lithotripsy (EHL) for pancreatic duct (PD) stones using SpyGlass. METHODS: We retrospectively audited the use of SpyGlass (Legacy and DS) + EHL. Indication, procedural details, and clinical outcomes were assessed...

Biliary angiodysplasia is extremely rare. Our background search revealed only a few case reports in the English literature. We present a case of angiodysplasia of the proximal common bile duct in a patient with subacute upper gastrointestinal bleeding and symptomatic anemia. A standard esophagogastroduodenoscopy with subsequent dedicated duodenoscopy revealed blood-stained bile draining from the major ampulla orifice. A contrast-enhanced magnetic resonance cholangiopancreatography was unrevealing for any pancreaticobiliary pathology...

Pancreatic stent proximal migration is a well known complication of pancreatic duct stenting, which occurs in about 5-6% of cases. Serious complications should be avoided by retrieval of the stent via different endoscopic techniques. We report a new technique previously reported only once (in a pancreatic duct with underlying pathology), to remove the proximally migrated pancreatic stent in a normal pancreatic duct by SpyGlass Direct Visualization System (Boston Scientific, Natick, Massachusetts, USA) and SpyBite Forceps (Boston Scientific, Natick, Massachusetts, USA)...

BACKGROUND AND STUDY AIM: Indeterminate biliary strictures and difficult bile duct stones remain clinically arduous and challenging situations. We aimed to evaluate the utility of the single-operator cholangioscopy (SOC)-system SpyGlass in both conditions in a single-center biliopancreatic interventional unit and in perspective of available aggregated literature. METHODS: Usefulness of SOC was assessed for the above-mentioned indications by means of the combination of successful procedural completion, clinical success and incidence of procedure-related adverse events in our own prospective cohort from 3/2010 to 7/2014 and all available literature till 6/2015...

A number of case studies have described the usefulness of peroral cholangioscopy for diagnosis and therapy, performed by visualizing the inner cavity of the bile duct. Currently available types of peroral cholangioscopy include peroral videocholangioscopy (POCS) using a mother-baby scope system (MBSS), direct peroral videocholangioscopy (D-POCS), and SpyGlass™ Direct Visualization System (SGDVS). POCS started with cholangioscopy using MBSS, requiring two skilled endoscopists using two endoscopic systems. On the other hand, D-POCS and SGDVS were developed as single-operator techniques...

BACKGROUND AND AIMS: ERCP is an established technique for the management of bile duct stones. Large bile duct stones (>1.2 cm) require additional techniques such as mechanical lithotripsy and balloon sphincteroplasty for ductal clearance. The literature on endoscopic management of cystic duct stones (CDSs) and Mirizzi syndrome (MS) is limited. We report our experience with cholangioscopy-assisted extraction of CDSs and MS in patients in whom conventional endoscopic and surgical techniques failed...

BACKGROUND AND AIMS: Anastomotic biliary strictures are common in patients that undergo living donor liver transplantation. Although endoscopic management has the advantage over percutaneous approaches, the initial success rate for the endoscopic management is unsatisfactory. The SpyGlass system can be a useful device in patients with a severe anastomotic stricture. METHODS: The SpyGlass cholangioscopy-assisted guidewire placement was performed in 15 patients with a difficult guidewire placement in which the guidewire could not transverse the stricture with conventional methods for 10 min or more...

Peroral cholangioscopy is useful in differentiating benign from malignant biliary strictures. However, when conventional biliary access via endoscopic retrograde cholangiopancreatography (ERCP) fails, percutaneous transhepatic cholangioscopy (PTCS) via the SpyGlass cholangioscopy system can be used to achieve a diagnosis. Four patients with biliary strictures in whom conventional ERCP was not possible and percutaneous brushings were either nondiagnostic or unsatisfactory were investigated with PTCS. The technique of PTCS involves insertion of the SpyGlass cholangioscope through a percutaneous transhepatic sheath, placed just prior to the procedure, to visualize the stricture and obtain biopsies with the SpyBite forceps...

A fifty-five year old female patient presented with jaundice, subfebrile fever and dark yellow urine since one month before admission. She lost weight 10 kilograms during one month. One day before admission to Ciptomangunkusumo General Hospital, she complained of worsened abdominal pain at right upper quadrant urging her to come to the emergency room. An abdominal examination revealed Murphy sign, mild hepatomegaly and deeply icteric sclera. Serum bilirubin was 21.8 mg/dl, alkaline phosphatase and gamma-glutamyltransferase levels were significantly elevated (1090 IU/L and 560 IU/L consecutively) while the transaminases were moderately high (ALT 80 U/L)...

CONTEXT: Direct endoscopic visualization of biliopancreatic duct is certainly one of the greatest advances of therapeutic endoscopy. The use of a single-operator cholangioscopy platform (SpyGlass) is a promising technique in the evaluation of diseases such as indeterminate biliary stricture and giant choledocholitiasis. This is the first Brazilian case series using this technology. METHODS: We report a case series of 20 patients in whom SpyGlass was used with diagnostic and therapeutic intention...
