- InterventionsA randomized, single-blind, single center, cross-over study. Study product (both groups): Nutritison Fiber during 12 h. Next day digestion and absorption test with labeled casein during 1 h. In this cross-over study each healthy subject participates in 2 visits, with a minimal washout period of 4 weeks in between. Subjects are randomly assigned to one of two groups by a computer randomization program. Group I receives the first visit enteral nutrition (EN) through a naso-gastric tube and the second visit through a naso-jejunal tube and group II receives EN in opposite order.
X-ray abdomen with contrast to confirm position of tube. Venous canula in forearm or dorsal vein. Applying continuous glucose monitor system.
- Primary outcomeDifferences in digestion and absorption on the administration of enteral nutrition either gastric or distal to the ligament of Treitz in the jejunum. Primary parameter: Labeled phenylalanine.
- Secondary outcomeDifferences in endocrine responses to the administration of enteral nutrition either gastic or distal to the ligament of Treitz in the jejunum. Parameters: Amino acid profiles, hormone responses, Glucose, insulin, C-peptide response, Fatty acid profile, Folic acid, Vitamin B12, and iron.
- TimepointsThe duration of the study for each subject from randomisation to the end of the study ideally is 6 weeks. In the first 5 weeks the subject will be admitted 2 times for 3 days, with a 4 week interval. Follow-up includes a phone call 1 week after every visit.

- Brief summaryEnteral feeding is the preferred method of nutritional support in patients who have a functioning gastrointestinal (GI) tract but cannot maintain an adequate oral intake. There are various ways of administrating EN. The consequences of gastric or jejunal feeding with respect to changes in levels of amino acids (AA) and serving the nutritional requirements of the patient are currently unknown. Therefore, it is proposed that the differences in the responses to gastric and jejunal feeding with a main focus on digestion and absorption of AA will be determined.
