  Fig. 1. (A) Underwater endoscopic view of the grade 1 neuroendocrine tumors. (B) Poor endoscopic view due to the accumulation of water and a mixture of air bubbles or intestinal fluids. (C) The gel easily prevented the formation of air bubbles and did not mix with the intestinal fluids, resulting in a good field of view and facilitating snaring. (D) Spurting bleeding did not spread into the gel, and the field of view remained clear.
