Course Description
ESS was made possible with the development of NOTES, a concept that was first introduced in 2004 through experimental transgastric pertioneoscopy. The core of the ESS is the mucosal flap valve technique. Currently, this technique is being widely used in endoscopic treatment, and we have designated the term ”endoscopic submucosal surgery” to this method.

  • Concept of Endoscopic Submucosal Surgery (ESS)
  • History of ESS
  • Clinical Applications
