 This chapter introduces a history of pit pattern diagnosis and its basic rule. In addition, it describes the correlation between pit pattern diagnosis and magnifying NBI findings with some data of our clinical research. We evaluated the correlation between pit pattern and JNET classification using consecutive colorectal tumors comprising hyperplastic polyp, sessile serrated polyp, adenoma, and early cancer. NBI findings(pit-like pattern)nearly corresponded to pit pattern in lesions with regular surface pattern(JNET Type 1, 2A). Conversely, NBI findings(pit-like pattern)and pit pattern were not always the same in lesions with irregular surface pattern(JNET Type 2B, 3). In such case, NBI appearance tends to be more irregular than pit pattern. A difference certainly exists between surface pattern(pit-like pattern)in NBI and real pit pattern. Hence, it is essential to be familiar with each histopathological characteristic and diagnostic feature to use them most effectively in daily colonoscopy.
