nteral nutrition has been recognized as an efficient route of nutritional management in patients not only after surgical insults but with chronic diseases.Percutaneous endoscopic gastrostomy (PEG)is one of the important and easy routes of enteral access that has frequently been used for patients who are unable to take food orally[1].The numbers of PEG performed in Japan have been getting increased rapidly in recent years,because PEG is safe and minimally-invasive.Furthermore,PEG is convenient as it is not only used for continuous enteral feeding,but for gastrointestinal decompression[2].While metaanalysis in Western countries has demonstrated that enteral nutrition through percutaneous endoscopic gastrostomy (PEG) did not improve clinical outcome in patients with severe dementia[3],precise clinical outcome and prognosis in patients in whom enteral nutrition through percutaneous endoscopic gastrostomy was performed has not been well documented in Japan.
