[Application of percutaneous endoscopic gastrostomy in patients with neurological diseases].

Percutaneous endoscopic gastrostomy (PEG) has been increasingly used in treating patients with neurogenic dysphagia to improve nutrition status and prevent choking. PEG is mostly used for stroke and amyotrophic lateral sclerosis, although more evidence-based researches are required to assess the timing, risks, and survival benefits. Its application in senile dementia is still controversial.
