Pedro Pereira, Armando Peixoto, Patrícia Andrade, Guilherme Macedo
Smaller endoscopes and catheters have been developed that permit direct visualization of the bile and pancreatic ducts (cholangioscopy and pancreatoscopy, respectively). These endoscopes and catheters are passed through the working channel of a standard therapeutic duodenoscope during endoscopic retrograde cholangiopancreatography (ERCP). The SpyGlass Direct Visualization System (Boston Scientific Corp, Natick, MA, USA) is currently the most widely used and studied device. Cholangioscopy with intraductal lithotripsy has become an established modality in the treatment of difficult biliary lithiasis...

Background and study aims I-SCAN is a computed virtual chromoendoscopy (CVC) system designed to enhance surface and vascular patterns. In this study, we evaluated the usefulness of direct peroral cholangioscopy (POC) using I-SCAN compared with a conventional white-light image (WLI) to diagnose bile duct lesions. Patients and methods Patients with mucosal lesions in the bile duct detected during direct POC were enrolled prospectively. The quality of endoscopic visualization and the visual diagnosis were assessed using I-SCAN and WLI modes, respectively, during direct POC...

Background and study aims We present the first clinical results of a new tandem technique for direct peroral cholangioscopy using a standard ultraslim upper gastrointestinal endoscope and a guide probe that was originally developed for the non-transendoscopic placement of biliary endoprostheses (guide probe of Kautz; MTW, Wesel, Germany). Patients and methods Twenty direct peroral cholangioscopy procedures were performed with the new anchor-assisted method using the guide probe of Kautz in a single center and were retrospectively analyzed...

Biliary complications are the most common post-liver transplant (LT) complications with an incidence of 15%-45%. Furthermore, such complications are reported more frequently in patients who undergo a living-donor LT (LDLT) compared to a deceased-donor LT (DDLT). Most post-LT biliary complications involve biliary strictures, bile leakage, and biliary stones, although many rarer events, such as hemobilia and foreign bodies, contribute to a long list of related conditions. Endoscopic treatment of post-LT biliary complications has evolved rapidly, with new and effective tools improving both outcomes and success rates; in fact, the latter now consistently reach up to 80%...

Recently, the novel SpyGlass DS Direct Visualization system (SPY DS) has become available. This system offers several advantages over the conventional SPYGlass system. This study evaluated the clinical feasibility and efficacy of diagnostic and therapeutic procedures for biliary disorder using SPY DS.In this retrospective study, consecutive patients who had biliary disorder were enrolled between November 2015 and February 2016. All patients could not be diagnosed or treated by standard endoscopic retrograde cholangiopancreatography in our hospital or at another hospital...

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...

The widespread dissemination of direct cholangioscopy (DC) has been hindered by the need for special equipment and the perceived high procedure-related technical complexity. DC with freehand intubation has been reported to have high technical success rates in a single report, albeit the pervasive expert opinion question its clinical applicability, thus most centers resort to anchoring techniques for intubation and/or scope advancement.[1] However, although newer anchoring balloons are being developed, first-generation balloons have been withdrawn from the market...

BACKGROUND: Bile duct stones after hepaticojejunostomy are considered a troublesome adverse event. Although percutaneous transhepatic procedures using a cholangioscopy is performed to treat these bile duct stones, a peroral endoscopic procedure using a short, double-balloon enteroscope (sDBE) is an alternative. This study aimed to compare the immediate and long-term outcomes of both treatments for bile duct stones in patients who underwent prior hepaticojejunostomy. METHODS: Between October 2001 and May 2013, 40 consecutive patients were treated for bile duct stones after hepaticojejunostomy at a tertiary care hospital...

Bile duct brush cytology, intraductal biopsy and EUS-FNA are all used to characterize biliary strictures, with suboptimal sensitivity. Surgical resection without confirmed malignancy is undesirable. Cholangioscopy with targeted biopsies appears to increase the diagnostic yield in indeterminate biliary strictures, but it is still considered optional.

Hepatobiliary cystadenomas (HBC) is a rare neoplasm which comprising less than one percent of liver cystic neoplasms. Although it's known as a benign tumor, but they have a potential for neoplastic transformation. Making a proper diagnosis and ruling out of other differential diagnosis is important because of different treatment. In the present study, we described a case of HBC manifested as idiopathic dominant biliary stricture in common hepatic duct (CHD), on the basis of spiral CT scan and MRI, and elevated CA19-9...

An 82-year-old woman who had been suffering from repeated obstructive jaundice for 7 years was referred to our hospital. Although endoscopic aspiration of the mucin in the common bile duct had been temporally effective, origin of the mucin production had not been detectable. The patient thus had been forced to be on long-term follow-up without curative resection. Endoscopic retrograde cholangioscopy on admission revealed massive mucin in the common bile duct. In addition, an anomalous bile duct located proximal to the gallbladder was identified...

Jason Deforest Jones, Rishi Pawa
Mirizzi syndrome is an exceptionally rare diagnosis with an annual incidence of less than 1% in developed countries. In this disease process, stone burden in the cystic duct or gallbladder neck leads to common hepatic duct obstruction, either by mechanical compression or secondary inflammation. Mirizzi syndrome is classified into one of four types based on the presence and severity of cholecystobiliary fistulization. Treatment is primarily surgical in nature and largely dictated by the type of Mirizzi syndrome encountered...

BACKGROUND AND AIMS: Advances in imaging technology have improved the annual detection rate of pancreatic cystic lesions (PCLs), but the preoperative diagnosis of PCLs remains unclear. Thus, the usefulness of single-operator cholangioscopy (SOC) as a diagnostic imaging tool for PCLs is worth investigating. We performed an intracystic visual examination of PCLs using SOC to determine the diagnostic value of SOC for PCLs. METHODS: In this retrospective observational study, PCLs were confirmed using a diagnostic imaging modality...

PURPOSE OF REVIEW: Primary sclerosing cholangitis (PSC) is associated with an increased risk of hepatobiliary and extrahepatic malignancy. Particularly the risk of cholangiocarcinoma (CCA) is greatly increased. To provide potentially curative treatments for affected patients an early diagnosis of CCA is crucial. We here review the current advances with respect to CCA diagnosis and surveillance and discuss a rational approach on how to perform surveillance of CCA in PSC patients. RECENT FINDINGS: Given the shortcomings of the current modalities for the surveillance and diagnosis of CCA in PSC, recent studies have focused on novel biomarkers for CCA...
