n. a procedure in which an opening is made into the stomach from the outside. It is usually performed to allow food and fluid to be introduced into the stomach through a tube. It is indicated when swallowing is considered unsafe due to a neurological condition, such as stroke, multiple sclerosis, or motor neuron disease. 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).
