| [ Summary ] | Subdivisions of type V pit patterns were consolidated at the Hakone Pit Pattern Symposium, in April, 2004. It was determined that type VN pit patterns only showed the area of apparent nonstructure. Therefore, the classification of pit patterns became easy to understand by abecedarian and foreigners, 13.9 % of colorectal lesions which showed type VI pit patterns and 86.9 % of colorectal lesions which showed type VN pit patterns, which had invaded deeply into the submucosal layer (so-called sm massive cancers) by the former classification. With a classification based on the Hakone consensus, the lesions which showed new type VN pit patterns and were considered sm massive cancers. Because the number of sm massive cancers with VI pit patterns has increased, we must examine these indexes which represent sm massive cancers. | |
