“…In May 2019, a next generation “mother-baby” videocholangioscope system (CHF-B290, Olympus Medical Systems Corporation, Tokyo, Japan) was introduced[ 80 , 81 ]. Despite being a newer iteration with notable improvements, some previously known limitations ( e.g.…”

“…Despite being a newer iteration with notable improvements, some previously known limitations ( e.g. two endoscopist operators and two equipment towers) remain, while others, such as scope fragility and accessory channel diameter, have been reported to be improved[ 80 ]. Currently, this system is only available for use in certain markets in Asia and Europe[ 80 ].…”

Peroral cholangioscopy (POC) is an endoscopic procedure that allows direct intraductal visualization of the biliary tract. POC has emerged as a vital tool for indeterminate biliary stricture evaluation and treatment of difficult biliary stones. Over several generations of devices, POC has fulfilled additional clinical needs where other diagnostic or therapeutic modalities have been inadequate. With adverse event rates comparable to standard endoscopic retrograde cholangioscopy and unique technical attributes, the role of POC is likely to continue expand. In this frontiers article, we highlight the existing and growing clinical applications of POC as well as areas of ongoing research.

“…The efficacy of different types of POC in stone removal is also a consideration. In a retrospective study involving 32 patients who failed conventional ERCP for stone removal, Murabayashi et al [ 87 ] noted that both DSOC and videocholangioscope (CHF-B260) achieved a 100% complete stone removal with similar adverse event rates. However, DSOC was noted to have significantly shorter procedural time (67 ± 30 minutes vs 107 ± 64 min), and a lesser number of endoscopic sessions were needed (1.35 ± 0.49 vs 2.00 ± 0.85)[ 87 ].…”

Choledochoscopy, or cholangioscopy, is an endoscopic procedure for direct visualization within the biliary tract for diagnostic or therapeutic purposes. Since its conception in 1879, many variations and improvements are made to ensure relevance in diagnosing and managing a range of intrahepatic and extrahepatic biliary pathologies. This ranges from improved visual impression and optical guided biopsies of indeterminate biliary strictures and clinically indistinguishable pathologies to therapeutic uses in stone fragmentation and other ablative therapies. Furthermore, with the evolving understanding of biliary disorders, there are significant innovative ideas and techniques to fill this void, such as nuanced instances of biliary stenting and retrieving migrated ductal stents. With this in mind, we present a review of the current advancements in choledo-choscopy with new supporting evidence that further delineates the role of choledochoscopy in various diagnostic and therapeutic interventions, complications, limitations and put forth areas for further study.

“…However, treating PDS with ERCP alone has always been a great challenge. The application of SpyGlass makes ERCP move towards direct visualization, which can reduce the frequency of angiography ( 4 ). Electrohydraulic lithotripsy (EHL) or laser lithotripsy (LL) under SpyGlass can crush large and pressure-resistant stones into smaller fragments, significantly improving the endoscopic treatment of large stones, and appears to be a good alternative and a very successful therapeutic approach.…”

Electrohydraulic lithotripsy through endoscopic retrograde cholangiopancreatography combined with SpyGlass in the treatment of complex pancreatic duct stones: A case report and literature review

The incidence of pancreatic duct stones (PDS) is less than 1%. After the formation of stones, the lumen of the pancreatic duct is blocked, and the pancreatic juice cannot be discharged smoothly, resulting in the impairment of the internal and external secretions of the pancreas. Several national guidelines now recommend endoscopic retrograde cholangiopancreatography (ERCP) as the treatment for PDS. The emergence of SpyGlass makes it possible to visualize the ERCP blind area of the pancreatic system directly. Electrohydraulic lithotripsy (EHL) under SpyGlass can crush large and pressure-resistant stones into smaller fragments, significantly improving the success of the endoscopic treatment of large stones. Here, we report a patient presented with acute alcohol-associated pancreatitis, found to have PDS on imaging, who underwent ERCP combined with SpyGlass (EHL), avoiding surgery, reducing trauma, and being discharged from the hospital with a rapid recovery. Therefore, endoscopic therapy is effective and safe for PDS patients. The combination therapy of this patient is the first use of SpyGlass for PDS in our centre, which marks a new stage in the application of endoscopic therapy for pancreatic diseases.
