The Internal medicine endoscopy course in small animals using natural orifices is designed for clinicians with no or basic skills in flexible and rigid endoscopy. We cover instrument handling from how to set up the endoscope to maintenance and cleaning. Many tricks are discussed and shown since both course masters have been involved in endoscopic teaching for many years. Classroom teaching on all aspects of endoscopy in internal medicine, starting from indications to complications, procedures and possible findings will be followed almost daily by a practical wet lab with various models (including ex-vivo organs) and live piglets.
