Percutaneous endoscopic gastrostomy is an endoscopic medical 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. The procedure is an alternative to surgical gastrostomy insertion, and does not require a general anesthetic; mild sedation is typically used. PEG tubes may also be extended into the small intestine by passing a jejunal extension tube (PEG-J tube) through the PEG tube and into the jejunum via the pylorus.
