 Although it is important to provide histopathological support to the vascular pattern of magnifying endoscopic classification, it is often difficult to establish a one-to-one correlation between a blood vessel recognized endoscopically and that recognized on a tissue section. We employed three-dimensional reconstruction of serial sections as a solution for correlating the histological image and endoscopic pattern of blood vessels. Type B1 vessels preserve the original IPCL(intra-epithelial papillary capillary loop)structure, with the blood supply and drain being proximally close to each other and located in the shallow layers of the lamina propria ; thus, the loop structure can be easily recognized endoscopically. Conversely, in type B2 and B3 vessels, the original IPCL structure and subepithelial vessels are damaged with an increased connectivity to the submucosal blood vessels, enabling blood supply and drain to the deep part. Additionally, the distance between them is increased, making it difficult for the loop to be recognized from the surface. Based on these findings, we considered the existence of an association between the magnifying endoscopic and histopathological findings.
