Percutaneous endoscopic gastrostomy: An update on its indications, management, complications, and care.

BACKGROUND Numerous disorders impairing or diminishing a patient's ability to swallow may benefit from a PEG tube placement. This is considered the elective feeding technique if a functional digestive system is present. METHODS A PubMed-based search restricted to the English literature from the last 20 years was conducted. References in the results were also reviewed to identify potential sources of information. RESULTS PEG feeding has consistently demonstrated to be more effective and safe than nasogastric tube feeding, having also replaced surgical and radiological gastrostomy techniques for long term feeding. PEG is considered a minimally invasive procedure to ensure an adequate source for enteral nutrition in institutionalized and at home patients. Acute and chronic conditions associated with risk of malnutrition and dysphagia benefit from PEG placement: Beyond degenerative neuro-muscular disorders, an increasing body of evidence supports the advantages of PEG tubes in patients with head and neck cancer and in a wide range of situations in pediatric settings.The safety of PEG placement under antithrombotic medication is discussed. While antibiotic prophylaxis reduces peristomal wound infection rates, co-trimoxazole solutions administered through a newly inserted catheter constitutes an alternative to intravenous antibiotics. Early feeding (3-6 hours) after PEG placement firmly supports on safety evidences, additionally resulting in reduced costs and hospital stays. Complications of PEG are rare and the majority prevented with appropriated nursing cares. CONCLUSIONS PEG feeding provides the most valuable access for nutrition in patients with a functional gastrointestinal system. Its high effectiveness, safety and reduced cost underlie increasing worldwide popularity.
