Feasibility of new-generation endocytoscopy for the real-time diagnosis of ampullary lesions: A pilot study (with video)

An early and accurate diagnosis of ampullary neoplasia is crucial; however, sampling bias is still a major concern. New-generation endocytoscopy enables real-time visualization of cellular structures and enables an accurate pathological prediction; however, its feasibility for small ampullary lesions has never been investigated.
