Core tip: Keeping up with new developments in the fast-moving field of enteral nutrition is a challenge for any gastroenterologist. While enteral tube feeding plays a major role in the care of critically ill patients and those with poor voluntary intake, chronic neurological or mechanical dysphagia or gut dysfunction, mechanical, gastrointestinal, infectious and metabolic complications can lead to serious conditions or death.

In addition, we address prophylactic measures to prevent complications, problem solutions and special aspects.
