Direct pancreatoscopy has inherent limitations, which include lack of instrument availability, scope fragility, small image size, lack of traditional endoscope features, and need for two endoscopists. Despite the above, centers with large pancreaticobiliary referral practice will selectively use this technology both diagnostically and therapeutically. The variability of pancreatic duct angulation and diameter, the presence of variably obstructing stenoses or filling defects, and the need to concomitantly apply this technology to the biliary tree all suggest that a family of miniscopes will be required as opposed to a single "ideal" instrument.
直接胰管镜检查存在固有的局限性，包括仪器难以获取、镜身易碎、图像尺寸小、缺乏传统内镜的特性以及需要两名内镜医师操作。尽管如此，拥有大量胰胆管转诊业务的中心仍会选择性地将这项技术用于诊断和治疗。胰管角度和直径的变异性、存在不同程度的梗阻性狭窄或充盈缺损，以及需要同时将这项技术应用于胆管，所有这些都表明需要一系列微型内镜，而不是单一的“理想”器械。
