The importance and prevalence of the superficial lesions in the colon and rectum caught worldwide public attention in 2008 when Soetikno and colleagues reported the prevalence of non-polypoid (flat and depressed) colorectal neoplasms in asymptomatic and symptomatic adults in North America and the public media disseminated their findings. The publication put to rest the question of whether or not the flat and depressed colorectal neoplasms exist in Western countries; flat and depressed colorectal neoplasms can be found throughout the world. In this article, the author highlights the importance of the macroscopic classification of the colorectal neoplasm and emphasizes the distinction between so-called flat lesions (IIa and IIb) and 0-IIc (superficial depressed) neoplastic colorectal lesions.
2008年，当Soetikno及其同事报告北美无症状和有症状成年人中非息肉样（扁平及凹陷性）结直肠肿瘤的患病率，且大众媒体传播了他们的研究结果时，结直肠浅表病变的重要性和患病率引起了全球公众的关注。该出版物解决了西方国家是否存在扁平及凹陷性结直肠肿瘤的问题；扁平及凹陷性结直肠肿瘤在世界各地都能被发现。在本文中，作者强调了结直肠肿瘤宏观分类的重要性，并着重指出所谓的扁平病变（IIa和IIb）与0-IIc（浅表凹陷性）结直肠肿瘤性病变之间的区别。
