[Tube feeding - who, how and when].

Summary. The concept of enteral nutrition is well established for a long time. During the past twenty years different percutaneous tube feeding techniques have been established. The most popular method is the percutaneous endoscopic gastrostomy (PEG) which is applied as a pull-through technique in Germany. In some patients this approach is not successful and alternative techniques must be used (e. g. introducer method). In some patients nasal or percutaneous feeding tube have to be placed directly into the intestine. There are different systems available for this approach which have to be clearly indicated. As a second step after initiation of enteral nutrition therapy quality of life can be improved by implanting secondary systems (e. g. button gastrostomy).A standardized technique for inserting tubes is essential to have a successful long-term outcome in enteral nutrition and care after has to be integrated into the regimen. The aim of this article is to demonstrate different enteral nutrition tube techniques their indication, contraindication and long-term follow-up.
