Abstract
Cutting ability of water jet scalpel to the resected porcine gastric mucosa was evaluated to support endoscopic mucosal resection(EMR)for early gastric cancer. We could use the mucosal gutter by water jet incision for easily placing the snaring forcept and grasping the lesion. When the water jet flow with over 30kgf/cm^2 at the point of needle chip penetrated the mucosal muscle, the mucosal surface was elevated owing to the submucosal retention of the emitted fluid. The proper muscle was kept intact. Circular incision with a diameter of 3cm was performed with 30kgf/cm^2 in 40s. We demonstrated that our method on water jet incision could be used for effective and safe method to suport EMR.
