“…[17][18][19] Because of the technical difficulty and risk for pancreatitis, both techniques are often used selectively in equivocal cases of MD involvement in patients who are high-risk surgical candidates or who request a more certain diagnosis before their operation.…”

“…Importantly, this study also found that there is no diagnostic value for pancreatic juice cytology in the diagnosis of pancreatic carcinoma. Since then, several case reports and case series have been published describing the role of cholangioscopy with the SpyGlass® system in diagnosing IPMNs in which dilatation of main pancreatic duct was sufficient, strengthening its high diagnostic accuracy [38][39][40]. In a recent Japanese prospective multicenter study with the use of SpyGlass® cholangiopancreatoscopy, 24 out of 148 were submitted to pancreatoscopy, out of which 16 had a suspicion of IPMN.…”

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

“…In this same review, lavage cytology was the best approach with a sensitivity of 46% and a specificity of 98%. New technologies for tissue sampling such as intrapancreatic videoscope with fiberoptic probes have been tested (66), showing excellent results with 100% sensitivity and specificity for detecting malignancy via irrigation cytology in patients with dilated MDs (67). Despite these promising results, ERCP is rarely indicated for PCN diagnosis due to the inherent risks related to the procedure and the current insufficient diagnostic accuracy.…”

The real prevalence of pancreatic cystic lesions remains unknown. The malignant potential of some of these lesions remains a cause for significant concern. Thus, it is mandatory to develop a strategy to clearly discriminate those cysts with a potential for malignant transformation from those that do not carry any significant risk. Intraductal papillary mucinous neoplasms and mucinous cystadenomas are mucinous cystic neoplasms with a known malignant potential that have gained greater recognition in recent years. However, despite the numerous studies that have been carried out, their differential diagnosis among other cysts subtypes and their therapeutic approach continue to be a challenge for clinicians. This review contains a critical approach of the current recommendations and management strategies regarding intraductal papillary mucinous neoplasms and mucinous cystadenomas, as well as highlighting the limitations exposed in current guidelines.
