<unk>  may be indicated in numerous situations, usually those in which normal (or nasogastric) feeding is impossible. The causes for these situations may be neurological (e.g. stroke), anatomical (e.g. cleft lip and palate during the process of correction) or other (e.g. radiation therapy for tumors in head & neck region). In certain situations where normal or nasogastric feeding is not possible,<unk>  may be of no clinical benefit. In advanced dementia, studies show that<unk>  placement does not in fact prolong life. Instead, oral assisted feeding is preferable. Quality improvement protocols have been developed with the aim of reducing the number of non-beneficial<unk> es in patients with dementia. A<unk>  can be placed to decompress the stomach contents in a patient with a malignant bowel obstruction. This is referred to as a "venting<unk> " and is placed to prevent and manage nausea and vomiting. A<unk>  can also be used to treat volvulus of the stomach, where the stomach twists along one of its axes. The tube (or multiple tubes) is used for gastropexy, or adhering the stomach to the abdominal wall, preventing twisting of the stomach. A<unk>  tube can be used in providing gastric or post-surgical drainage.
