Peroral pancreatoscopy (POPS) under duodenoscopic assistance provide direct visual assessment of the pancreatic duct, tissue sampling, and therapeutic interventions. Sometimes, pancreatoscopy can confirm accurate diagnosis, such as differential diagnosis of filling defects between intraductal tumors and stones. However, it is often difficult to differentiate malignant from benign strictures solely on pancreatoscopy. It is currently considered that intraductal papillary mucinous neoplasm (IPMN) is the most suitable indication of POPS. POPS has several problems: image resolution, fragility and maneuverability. Concerning image resolution, the quality has been improved with the development of a video pancreatoscope. Moreover, the recently developed endoscopic optical technology of narrow band imaging (NBI) is now available to video pancreatoscopy. This will allow direct visual assessment. Although currently POPS has several problems, further improvement will assist POPS to become a useful modality in combination with NBI.
