Technical aspects of enteral nutrition.

Abstract

Advances in technical aspects of enteral feeding such as the manufacture of tubes from polyurethane or silicone have helped promote the science of enteral nutrition. Nasoenteral tubes have few complications, apart from a high unwanted extubation rate and some reluctance from patients because of cosmetic unacceptability. Needle jejunostomy has low morbidity but can only be placed at laparotomy. Percutaneous gastrotomy (in all its different guises) has been established as a low risk procedure and is the access route of choice for longterm enteral feeding, in particular for cancer, geriatric, and neurological patients.
