Usefulness of a novel slim type FlushKnife-BT over conventional FlushKnife-BT in esophageal endoscopic submucosal dissection

Figure 2 Water aspiration speed. A total of 200 mL water in a graduated cylinder was aspirated by scopes with 2.8-mm and 3.2-mm channels with FlushKnife-BT or FlushKnife-BTS inserted, and the amount of aspirated water in 10 s was measured. The column denotes mean data and the bar shows the range of experiments performed 9 times. Water aspiration speed was markedly faster with FlushKnife-BTS than with FlushKnife-BT. ^aP < 0.05, BT vs BTS. FlushKnife-BT: Ball-tipped FlushKnife; FlushKnife-BTS: A novel slim type FlushKnife-BT.
