PURPOSE OF REVIEW: Every year more than one million people worldwide undergo an endoscopic retrograde cholangiopancreatography (ERCP) for disorders of the bile duct system. This review aims to discuss recent clinical data with regard to single-operator peroral cholangioscopy (POC). RECENT FINDINGS: Innovations and technical optimizations of POC devices have extended diagnostic and therapeutic options for patients with complex biliary disease. Most of the currently available clinically relevant data are obtained with the single-operator peroral cholangioscopy (SOC)-system SpyGlass, which in a period of a decade has evolved further to a digital platform with increasing applicability, usefulness and cost-effectiveness...

An 89-year-old man was referred to our hospital for treatment of hepatolithiasis causing recurrent cholangitis. He had undergone a prior Whipple procedure. Computed tomography demonstrated left-sided hepatolithiasis. First, we conducted peroral direct cholangioscopy (PDCS) using an ultraslim endoscope. Although PDCS was successfully conducted, it was unsuccessful in removing all the stones. The stones located in the B2 segment were difficult to remove because the endoscope could not be inserted deeply into this segment due to the small size of the intrahepatic bile duct...

AIM: Perihilar cholangiocarcinoma (PHC) is a challenging disease and requires aggressive surgical treatment in order to achieve curation. The assessment and work-up of patients with presumed PHC is multidisciplinary, complex and requires extensive experience. The aim of this paper is to review current aspects of diagnosis, preoperative work-up and extended resection in patients with PHC from the perspective of our own institutional experience with this complex tumor. METHODS: We provided a review of applied modalities in the diagnosis and work-up of PHC according to current literature...

Mechanical complications in peritoneal dialysis (PD), including intraluminal clogging of the PD catheter by fibrin, omentum, or blood clot, are major causes of outflow problems and, in rare cases, lead to technical failure. To visualize an intraluminal image of patients undergoing PD with ineffective ultrafiltration (UF), a SpyGlass fiber optic probe was inserted into the catheter, together with SpyBite biopsy forceps, should the removal of clogging materials be needed. Applying these transcatheter devices in 2 PD patients with unexplained UF failure led to the demonstration of omental plugging at the catheter tip in the first patient and demonstration of intraluminal blood clots in the second patient from whom clots were removal successfully...

BACKGROUND: Although previous studies have reported the possibility of therapeutic ERCP without fluoroscopy, more robust documentation of fluoroscopy-free common bile duct stone (CBDS) clearance is needed. Technically, "digital cholangioscopy" (DCS) may be used to confirm CBDS clearance. We aimed to compare the feasibility, safety, and radiation exposure between patients with CBDS undergoing stone removal by DCS and conventional ERCP (cERCP). METHODS: Fifty (50) consecutive patients with a CBDS size < 15 mm underwent DCS (SpyGlass DS Direct Visualization System, Boston Scientific, Marlboro, MA, USA) between December 2015 and October 2016...

Primary sclerosing cholangitis (PSC) remains a rare but potentially devastating chronic, cholestatic liver disease. PSC causes obstruction of intra- and/or extra-hepatic bile ducts by inflammation and fibrosis, leading to biliary obstruction, cirrhosis and portal hypertension with all associated sequelae. The most dreaded consequence of PSC is cholangiocarcinoma, occurring in 10-20% of patients with PSC, and with population-based estimates of a 398-fold increased risk of cholangiocarcinoma in patients with PSC compared to the general population...

Peroral cholangioscopy has been used since the 1970'es and provides direct visualization of the biliary tree, possibility of electrohydraulic or laser lithotripsy and visually guided biopsies. This paper presents an overview of the existing literature focusing on the Spyglass single-operator cholangioscopy system. Several studies indicate that cholangioscopy can improve therapy of difficult accessible biliary stones and histological diagnosis in patients with indeterminate bile duct stenoses.

The SpyGlass DS system is currently used as a direct video cholangioscope for biliary diagnostic and therapeutic procedures. In general, the SpyGlass DS cholangioscope is passed through the working channel of a duodenoscope and inserted into a bile duct via duodenal papilla. However, the procedure has been challenging in patients with altered gastrointestinal anatomy due to the retrograde route through a potentially tortuous afferent limb. A therapeutic colonoscope with variable stiffness can offer alternative guidance for SpyGlass DS cholangioscope in patients with surgically altered gastrointestinal anatomy...

The internal phylogeny of Chelicerata and the attendant evolutionary scenario of arachnid terrestrialization have a long and contentious history. Previous studies of developmental gene expression data have suggested that respiratory systems of spiders, crustaceans, and insects are all serially homologous structures derived from the epipods (outer appendage rami) of the arthropod ancestor, corresponding to an ancestral gill. A separate body of evidence has suggested that the respiratory systems of arachnids are modified, inverted telopods (inner rami, or legs)...

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...
