A method of providing nutrition to persons who have a normally functioning stomach and intestines but who are unable to take sufficient food by mouth, for example because of neurological conditions interfering with swallowing, such as CEREBRAL PALSY, MOTOR NEURONE DISEASE (MND) or following a severe STROKE; or because of impaired consciousness, for example after head injury; and to boost nutrition beyond what can be tolerated orally in certain debilitating conditions. About 15,000 such procedures are performed each year in the UK. The end of the gastrostomy cannula is sited in the stomach endoscopically, through an incision in the skin, and then secured with a ‘button’ on the surface of the abdomen through which nutrients can be delivered.
