“…In 1970, Rosch et al [1] and Urakami [2] independently described two different endoscopic methods for peroral cholangioscopy. Since then, several systems have been introduced; however, widespread adoption of POCPS has been hindered by technological obstacles until recently [3].…”

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. When used in the evaluation of indeterminate biliary strictures by experienced endoscopists in recognizing intraductal pathology, it increases the diagnostic yield of tissue sampling. Pancreatoscopy is complementary to other imaging modalities in the evaluation of intraductal papillary mucinous neoplasms of the pancreas and is emerging as a sole or adjunctive therapy to extracorporeal shock wave lithotripsy for the treatment of main pancreatic duct stones. It remains investigational in the diagnosis of pancreatic adenocarcinoma. Complications specific to the performance of cholangiopancreatoscopy include cholangitis, which is related to intraductal fluid irrigation.Abbreviations: EHL: Electrohydraulic lithotripsy; ERCP: Endoscopic retrograde cholangiopancreatography; ESWL: Extracorporeal lithotripsy by shock waves; ET: Endoscopic therapy; EUS: Endoscopic ultrasound; IPMN: intraductal papillary mucinous neoplasm; LL: Laser lithotripsy; MDCT: Multi-detector computed conventional tomography; MPD: Main pancreatic duct; MRCP: Magnetic resonance cholangiopancreatography; MRI: Magnetic resonance imaging; POCPS: Peroral cholangiopancreatoscopy; PSC: Primary sclerosing cholangitis

“…This procedure directly investigates the biliary tract endoscopically and benefits from directly assessing the mucous membrane so as to help evaluate the dignity of inconclusive lesions in the bile duct [9] . For the first time, this offered diagnostic options superior to other imaging procedures in this region [8,9] . In choledochoscopy, a general distinction is made between percutaneous transhepatic and retrograde endoscopic access using the so-called "mother-baby" endoscope technique [10,11] .…”

Different diagnostic procedures exist for the detection of bile duct lesions in clinical practice. However, neither retrograde contrast imaging of the bile duct endoscopic retrograde cholangiopancreatogram nor other imaging procedures allow a safe diagnosis of the lesions. Therefore choledochoscopy may be a useful diagnostic procedure in macroscopic assessing lesions of the bile duct. Even if the diagnostic sensitivity and specificity is not sufficient, first studies suggest an enhanced diagnostic accuracy for choledochoscopy. Since the progress of choledochoscopy has started in the 1970 different improvements were achieved. Meanwhile, the examination can be performed by an examiner and samples can be taken. Image and Resolution quality has improved over the past years, also. The SpyGlass system is a technically advanced cholangioscopic device to provide endoscopic diagnosis in case of inconclusive bile duct findings. Further more, two more lumina allow specific biopsy forceps and optical fibers for electrohydraulic or laser lithotripsy. The most frequent useful insert of SpyGlass in clinical practice are in complex gallstones and bile duct lesions of unclear dignity.

“…Peroral cholangioscopy (POCS) was initially described in the mid-1970's. One of the first reports demonstrated that a fiberscope of 8.8 mm diameter could be directly inserted through the mouth, into the biliary system after an endoscopic papillotomy, without the need of using a second scope as a guide [5] . This scope did provide a biopsy channel to obtain tissue samples.…”

Intraductal endoscopy describes the use of an endoscope to directly visualize the biliary and pancreatic ducts. For many years, technological challenges have made performing these procedures difficult. The "mother-baby" system and other various miniscopes have been developed, but routine use has been hampered due to complex setup, scope fragility and the time consuming, technically demanding nature of the procedure. Recently, the SpyGlass peroral cholangiopancreatoscopy system has shown early success at providing diagnostic information and therapeutic options. The clinical utility of intraductal endoscopy is broad. It allows better differentiation between benign and malignant processes by allowing direct visualization and targeted sampling of tissue. Therapeutic interventions, such as electrohydraulic lithotripsy (EHL), laser lithotripsy, photodynamic therapy, and argon plasma coagulation (APC), may also be performed as part of intraductal endoscopy. I n t ra d u c t a l e n d o s c o p y s i g n i f i c a n t l y i n c r e a s e s the diagnostic and therapeutic yield of standard endoscopic retrograde cholangiography (ERCP), and as technology progresses, it is likely that its utilization will only increase. In this review of intraductal endoscopy, we describe in detail the various endoscopic platforms and their diagnostic and clinical applications.
