I. Introduction
Over the past 30 years, endoscopy has become an essential tool in the diagnosis and therapy of digestive diseases. Technical developments in endoscopes and devices and the introduction of completely new and complex procedures characterize the field of digestive endoscopy. Therefore, both endoscopists and nurses seek educational opportunities, through lectures, seminars, workshops or fellowships, to obtain and maintain relevant knowledge and technical skills, and ultimately, to gain competencies relevant to their clinical work in endoscopy.
