 Cold snare polypectomy specimens are fragile ; therefore, the probability of specimen damage is high. We hypothesized suction button to be the cause of specimen damage and devised a new method to retrieve specimens without passing them through the suction button. Retrieval through device channel avoids specimen damage. During retrieval using polyp trap, 27/89 lesions were damaged, whereas during retrieval using the new method, only 1/68 lesion was damaged ; thus, the damage rate using the new method was evidently low. This suggested that passage through the suction button was the cause of specimen damage.
