Therapeutic access to the biliary system is generally limited to endoscopic or percutaneous approaches. A variety of percutaneous transhepatic biliary interventions are applicable for the diagnosis and treatment of biliary system pathologies, the majority of which may be performed in conjunction with one another. The backbone of nearly all of these interventions is percutaneous transhepatic cholangiography for opacification of the biliary tree, after which any number of therapeutic or diagnostic modalities may be pursued...

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...

Indeterminate biliary strictures represent a diagnostic challenge requiring further work-up, which encompasses a variety of diagnostic modalities. We report a very rare case of B-cell acute lymphocytic leukemia presenting as a biliary stricture following remission of acute myeloid leukemia, which was initially treated with allogenic stem cell transplant. After multiple diagnostic modalities were implemented with no success, the use of cholangioscopy-guided biopsies was the key for the final diagnosis.

Bo Sun, Bing Hu
Intraductal ultrasonography (IDUS) provides real-time, cross-sectional imaging of pancreatobiliary ducts and surrounding structures during endoscopic retrograde cholangiopancreatography using a high-frequency ultrasound (US) transducer. Hence, IDUS has been considered a sensitive tool in the evaluation of suspicious choledocholithiasis and neoplasms, to help distinguish between benign and malignant bile duct strictures or wall thickness, and to assess tumor extension and invasion depth. With the rapid development and enriched choices of sensitive diagnostic modalities include but are not limited to endoscopic US, peroral cholangioscopy, and confocal laser endomicroscopy, it is needed to systematically assess the role of IDUS in the investigation of pancreatobiliary diseases...

BACKGROUND: The accuracy of current endoscopic modalities for diagnosing cholangiocarcinoma in primary sclerosing cholangitis (PSC) is suboptimal. AIM: To evaluate the comparative effectiveness of endoscopic retrograde cholangiopancreatography (ERCP)-based modalities, independently or in combination, for the diagnosis of cholangiocarcinoma in patients with PSC-induced biliary strictures. METHODS: Searches of PubMed, EMBASE, Web of Science and the Cochrane Library databases were performed through December 2015...

Bilioenteric anastomosis strictures are a serious complication of biliary surgery, and often result in recurrent cholangitis, choledocholithiasis, biliary cirrhosis, and hepatic failure. Bilioenteric reconstructive surgery is the standard treatment of choice for such complications. However, percutaneous transhepatic cholangioscopy (PTCS), also known as per-oral endoscopic-guided intervention, is a less invasive procedure that is becoming an increasingly popular alternative. This review describes the PTCS procedure (including the preparation process), as well as the diagnostic and therapeutic role of PTCS in bilioenteric anastomosis strictures...

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...

BACKGROUND AND AIMS: Cholangiocarcinoma (CCA) is a leading cause of morbidity and mortality in patients with primary sclerosing cholangitis (PSC). Although several ERCP-based diagnostic modalities are available for diagnosing CCA, it is unclear whether one modality is more cost-effective than the others. The primary aim of this study was to compare the cost-effectiveness of ERCP-based techniques for diagnosing CCA in patients with PSC-induced biliary strictures. METHODS: We performed a cost utility analysis to assess the net monetary benefit for accurately diagnosing CCA using 5 different diagnostic strategies: (1) ERCP with bile duct brushing for cytology; (2) ERCP with brushings for cytology and fluorescence in situ hybridization (FISH)-Trisomy; (3) ERCP with brushings for cytology and FISH-Polysomy; (4) ERCP with intraductal biopsies; and (5) single-operator cholangioscopy (SOC) with targeted biopsies...

Endoscopic retrograde cholangiopancreatography (ERCP) is the gold-standard modality for diagnosis and therapy of bilio-pancreatic disease. In particular, peroral cholangiography (POCS) is a useful modality not only for diagnosing biliary disease, but also for therapeutic procedures such as electrohydraulic lithotripsy. The SPY-DS single-operator cholangioscope has recently become available, and offers favorable visualization, a wide view, suction function and a larger accessory working channel. However, if the duodenoscope cannot be advanced into the ampulla of Vater for reasons such as surgical anatomy, POCS cannot be performed...

Direct examination of the biliary tree with endoscopes has been a challenge since endoscopists began performing endoscopic retrograde cholangiopancreatography (ERCP) in the late 1960s. Previously, surgeons had used rigid instruments intraoperatively, which made examination difficult. The first direct cholangioscopy performed by an endoscopist was likely unintentionally done in a patient with postsurgical anatomy. Indirect imaging, ERCP, and percutaneous transhepatic cholangiography are helpful modalities for examining the biliary tree, but they are limited procedures, particularly with regard to the evaluation and treatment of strictures and bile duct stones...

BACKGROUND: Some biliary complications after liver transplantation (LT) are difficult to manage by endoscopic or radiologic intervention alone. In these cases, percutaneous transhepatic cholangioscopy (PTCS) can be used as an adjuvant option. METHODS: Patients who underwent PTCS for post-LT biliary complications between August 1992 and January 2016 were retrospectively reviewed. RESULTS: Fifteen patients underwent PTCS for post-LT biliary complications...

REVIEW
Milljae Shin, Jae-Won Joh
Apart from noticeable improvements in surgical techniques and immunosuppressive agents, biliary complications remain the major causes of morbidity and mortality after living donor liver transplantation (LDLT). Bile leakage and stricture are the predominant complications. The reported incidence of biliary complications is 15%-40%, and these are known to occur more frequently in living donors than in deceased donors. Despite the absence of a confirmed therapeutic algorithm, many approaches have been used for treatment, including surgical, endoscopic, and percutaneous transhepatic techniques...

BACKGROUND AND STUDY AIMS: Direct retrograde cholangioscopy (DRC) enables high quality video imaging of the bile ducts and allows intraductal treatment with optical control. We evaluated the feasibility, success, and complications of a new third-generation prototype cholangioscope. PATIENTS AND METHODS: All consecutive patients from two tertiary endoscopy centers who had undergone DRC with the prototype were included. Indications for DRC were: evaluation of indeterminate strictures, filling defects, and complex bile duct stones...
