Advantages of the pocket creation method (PCM). a Endoscopic view showing the well-visualized submucosa in the pocket. The conical transparent hood naturally provides both traction and counter traction to stretch the submucosal tissue. b Vertical approach against the lesion. c The PCM changes a vertical to a tangential approach by creating the pocket. The fixed tip of the endoscope is less influenced by cardiopulmonary movement.
