Abstract Text In recent years, underwater endoscopic mucosal resection (UEMR) has become very popular due to its superiority compared to conventional endoscopic mucosal resection (CEMR) regarding en-bloc, R0 resection and recurrence rates, as well as the procedure time by not requiring submucosal injection. However, intestinal fluids, bubbles or bleeding may decrease visibility conducting to instillation of large amounts of water or gas insufflation. In contrast, gel immersion endoscopic mucosal resection (GIEMR), which use a electrolyte-free gelling agent (e.g food thickener) that is easily prepared in the endoscopy room, may offer some advantages over UEMR due to its higher viscosity: it remains more stable in the lumen, requires smaller amounts of solution and offers a clear visual field despite intestinal fluid or bleeding. Furthermore, its heavier weight facilitates bleeding control by slowing effect [1] [2] [3] [4].
