Percutaneous endoscopic gastrostomy. Indications, care and complications.

Percutaneous endoscopic gastrostomy (PEG) is an effective and safe method for nutritional support in patients with malnutrition and impossibility of oral intake with an estimated survival higher than the months that require enteral nutrition beyond four weeks. The main indications include neoplasms of the upper air-digestive tract and neurological diseases, with dementia currently considered a controversial indication. Anatomical alterations and infectious diseases are the most frequent contraindications. There are different endoscopic techniques; the most widely used being the "pull" method, with a low mortality. Complications are more frequent in patients with multiple pathologies and the elderly. Wound infection, extraction of the tube, tube blockage and bronchoaspiratory pneumonia are the most prevalent complications. Adequate prior preparation of the patient and exhaustive maintenance of the tube can reduce the appearance of these.
