Jejunostomy: From 1 Different Sources

n. a surgical operation in which the jejunum is brought through the abdominal wall as a *stoma. It may enable the insertion of a jejunal catheter for short-term infusion of nutrients or other substances. A feeding jejunostomy is a tube inserted into the jejunum using endoscopic or surgical techniques to allow the introduction of nutrients. This may be required when disease, previous surgery, or refractory vomiting prevents the placement of a *gastrostomy (PEG) tube. A percutaneous endoscopic gastrojejunostomy (PEG-J) is a jejunal extension that is applied to an existing PEG tube.

Enteral Feeding

the process by which nutrients are delivered to the gut through a feeding tube – a *nasogastric tube, nasojejunal tube, a PEG tube (see gastrostomy), or a *jejunostomy tube. Polymeric feeds contain whole fats, protein, carbohydrates, vitamins, and minerals. Feeds that are easier to digest include peptide feeds (containing short protein chains instead of whole protein) and elemental feeds (containing amino acids rather than whole proteins). See artificial nutrition and hydration; nutrition.... enteral feeding

Gastrojejunostomy

n. a surgical operation in which the *jejunum is joined to an opening made in the stomach. This is usually done in preference to *gastroduodenostomy. See also jejunostomy.... gastrojejunostomy
