Colonoscopic diagnosis of @entity1586 is a rather easy task, although some small @entity1127 might be missed when they are situated around the steep angulation or behind the fold. A correct diagnosis of @entity1697 is difficult not only by colonoscopy but also by biopsy because the @entity5 focus may be small or not exposed on the polyp surface. Therefore, colonoscopic polypectomy is the best procedure of choice for correct histologic diagnosis of @entity189 . Only by polypectomy can correct diagnosis of @entity189 be made, although there are various endoscopic signs such as irregularity of the surface configuration and white spots on the surrounding mucosa suggesting @entity189 . Over the course of several years experience of colonoscopy we have encountered small flat elevations under 1 cm in diameter of which 58% were benign @entity652 and 42% contained minute foci of @entity189 . These small flat lesions might have been missed quite easily during routine examination in the past and they might play an important role in the pathogenesis of @entity694 . @entity1127 can be adequately treated by polypectomy only, whereas @entity189 needs further treatment as it has a risk of node @entity3 . Risk factors influencing @entity3 are lymphatic permeation, poorly differentiated @entity189 , massive invasion close to the cut end. Only when one of these findings is seen in the removed polyp, further surgical treatment must be considered. However, the @entity1 's general condition, age and site of the polyp should be carefully taken into account in order to choose the appropriate treatment in each individual case as the risk of @entity3 under such situations mentioned above is not so high. Management of @entity189 is still a controversial issue and a long-term, clinicopathologic study will be needed to solve this question.
