Non-invasive ventilation support during feeding tube placement in amyotrophic lateral sclerosis patients with moderate to severe ventilatory impairment: an update.

Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease characterized by motor neuron degeneration, leading to muscle weakness and respiratory issues. Enteral nutrition is used in ALS patients when they experience severe weight loss, dysphagia, dehydration, or a risk of aspiration pneumonia. Noninvasive ventilation (NIV) is essential for managing respiratory failure in ALS patients, especially during feeding tube placement procedures. This narrative review compares percutaneous endoscopic gastrostomy (PEG), percutaneous radiologic gastrostomy (PRG), and radiologically inserted G-tube (RIG) in ALS patients receiving NIV. Studies were found through electronic database searches of Medline and Embase from 2000 to June 2025, including the Cochrane Central Register of Controlled Trials (CENTRAL), EBSCO Online Research Database, and Scopus. The main outcome was the occurrence of adverse events during and within thirty days after gastrostomy tube placement in NIV. Eleven studies involving NIV during PEG/RIG procedures were included. NIV during PEG, RIG, or PRG placement seems to be safe for ALS patients, with few adverse events reported, though future studies with higher methodological quality are needed. Additionally, the review highlights the benefits of better nutritional support, improved quality of life, interdisciplinary teamwork, increased survival rates, and personalized care.
