so this trick is quite useful for your daily practice in colonoscopy here I show you the suction Mark again here at the pop and once you see your suction Mark you can concentrate and place in your PO in a nice position to perform a reection but there is another suction sign that I use for example you have a lesion and instead of suctioning next to it to find it again you suction on top of the leion like you see here here I am actively suctioning this suctioning is happening while the nures gives me this n and I start advancing these NES through the working channel of the endoscope this maneuver of suctioning will create a pseudo pop you see this was the flat leion and now this is really like a cile leion and the nice Trick In addition is that while you are advancing this snare down the working channel of the endoscope you will push the pop out because the working channel will be filled with the snare and then the air will push the pop out the air of you pushing the snare out
