Underwater endoscopic submucosal dissection with a conventional tapered hood. A: Accumulation of air bubbles in the hood causes visual field impairment during underwater endoscopic submucosal dissection; B: A conventional tapered hood (ST Hood Short Type; Fujifilm Medical, Tokyo, Japan). This hood has narrow holes in its sides to remove the liquid via the capillary phenomenon, which is inversely proportional to the cross-sectional area of the hole; C: When a conventional tapered hood is used, removal of air bubbles can sometimes be difficult due to the narrow hood tip opening and holes in its sides.
