Percutaneous endoscopic aastrostomy(PEG)is an endoscopic medica procedure in which a tube (PEG tube) is passed into a patient's stomach through the abdominal wall, most commonly to provide a means of feeding when oral intake is not adequate (for example, because of dysphagia or sedation). This provides enteral nutrition despite bypassing the mouth; enteral nutrition is generally preferable to parenteral nutrition. The PEG procedure is an alternative to open surgical gastrostomy insertion, and does not require a general anesthetic. mild sedation is typically used.
