The prerequisites for this procedure are a functionally intact GI tract and meaningful longevity of the patient. Nutritional support for patients suffering from cerebrovascular accidents, senile dementia, brain tumors, amyotrophic lateral sclerosis, trauma, and sequelae of extensive neurologic surgery, are the most common nutritional indications for PEG placement. Other appropriate indications include tumors of the oral cavity, head and neck tumors, and severe facial trauma leading to alteration or obstruction of the aerodigestive tract. PEG has been used for nutritional supplementation in patients with inflammatory bowel disease (IBD), short gut syndrome, and malabsorption syndrome. It has also been used in patients with normal swallowing, but inadequate oral intake, to improve their nutritional status. Examples include patients suffering from extensive burns, acquired immunodeficiency syndrome (AIDS) wasting syndrome, anorexia after bone marrow transplantation, and chronic illnesses, such as cystic fibrosis and congenital heart disease. However, the role of enteral feeding in AIDS wasting syndrome is controversial.
