 In recent years, the use of peroral cholangioscopy and pancreatoscopy has become increasingly common in the diagnosis and treatment of biliary and pancreatic diseases. Traditionally, diagnosis and treatment were performed using two-dimensional imaging with ERCP; however, with peroral cholangioscopy and pancreatoscopy, it is now possible to directly visualize lesions within the bile and pancreatic ducts. This enables not only visual diagnosis under direct observation but also targeted biopsy and therapeutic procedures such as lithotripsy for refractory bile duct and pancreatic stones. Recently, numerous disposable digital peroral cholangioscopes and pancreatoscopes have been developed. The remarkable advancements in image quality and maneuverability would not have been possible without a long history of technological progress and transformation. This article provides a comprehensive overview of the development of peroral cholangioscopy and pancreatoscopy, including the transition from fiberscopes to electronic scopes, the popularization of the single-operator method, and the development of direct peroral cholangioscopy. In addition, it highlights the evolution of related devices and improvements in endoscopic techniques, which have collectively contributed to the significant advancements in this field.
