[Endoscopic and surgical procedures for enteral nutrition]. / Endoskopische und chirurgische Techniken zur enteralen Ernährung.

Standardized management of oncology patients necessarily includes screening for nutritional risk. Weight loss of > 5 kg within 3 months and diminished food intake are warning signals even in overweight patients. In case oral nutrition is neither adequate nor feasible even by fortification or oral nutritional supplements, the implantation of a percutaneous endoscopic gastrostomy (PEG) or fine needle catheter jejunostomy (FNCJ) offers enteral access for long-term nutritional support. Although the indications derive from fulfilling caloric needs, endoscopic or operative measures are not considered to be an urgent or even emergency measure. The endoscopist or surgeon should be fully aware and informed of the indications and make a personal assessment of the situation. The implantation of a feeding tube requires informed consent of the patient or legal surrogates. The review summarizes recent indications, technical problems and complications.
