Gastrostomy: From 3 Different Sources
An opening in the stomach made surgically, usually connecting the stomach to the outside so that a feeding tube can be passed into the stomach or small intestine. Gastrostomy may be performed on people who cannot eat properly due to oesophageal cancer (see oesophagus, cancer of) or who are unable to chew and swallow due to a stroke. (See also feeding, artificial.)
An operation on the STOMACH by which, when the gullet is blocked by a tumour or other cause, an opening is made from the front of the abdomen into the stomach, so that ?uid food can be passed into the organ.
n. a procedure in which an artificial opening is made through the anterior abdominal wall into the stomach to allow direct access for feeding or gastric decompression. A gastrostomy is performed when swallowing is considered unsafe or impossible, due either to neurological disease (such as stroke, multiple sclerosis, or motor neuron disease) or to obstruction by a tumour. It is often used temporarily after operations on the oesophagus or head and neck area until healing has occurred. Formerly a gastrostomy was always performed surgically, but it can now be done using an *endoscope (percutaneous endoscopic gastrostomy, PEG) or by direct puncture under radiological guidance (radiologically inserted gastrostomy, RIG).
a condition in which feeding via a PEG tube (see gastrostomy) is blocked. It occurs when the internal retention disc (bumper) of the tube, which holds it in place inside the stomach, is overgrown by hypertrophic gastric mucosa and becomes embedded in the stomach wall. This serious complication requires surgical removal of the tube. It can be prevented by correct tube care: advancing, retracting, and rotating of the tube.... buried bumper syndrome
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
n. a former name for a surgical procedure in which a hollow needle is pushed through the wall of the stomach or intestines to release an abnormal accumulation of gas or fluid or to introduce a catheter for feeding (see gastrostomy; enterostomy).... enterocentesis
n. an illuminated optical endoscope used to inspect the interior of the gullet (oesophagus), stomach, and duodenum. For many years these were rigid or semi-rigid instruments affording only limited views, but their modern counterparts are flexible instruments that house advanced digital systems to allow high-definition imaging of the oesophagus, stomach, and the proximal segments of the duodenum. Biopsies can be taken of visualized areas of mucosal abnormality, and therapeutic procedures (e.g. to stop a bleeding ulcer, remove a polyp, insert a *gastrostomy, dilate a stricture, or insert a self-expandable metal stent) may be performed. As the same instruments can usually be introduced into the duodenum they are also known as gastroduodenoscopes or oesophagogastroduodenoscopes. —gastroscopy n.... gastroscope
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.... jejunostomy
