 The concept of classical HP(hyperplastic polyp)considered as non-neoplastic polyp has changed during the last several decades. It has been found that classical HP includes lesions with malignant potential and they have been defined as SSA/P(sessile serrated polyp/adenoma). If we could resect only SSA/P, it would be ideal. Unfortunately, so far, it has been difficult to differentiate SSA/P(neoplastic)from HP(non-neoplastic)during real-time colonoscopy. We have proposed a simple treatment strategy for SSA/P and HP made by their size and location.
