Introduction:

patients with amyotrophic lateral sclerosis (ALS) require nutritional support, in most cases with enteral nutrition through gastrostomy, either endoscopic (PEG) or radiological (PRG).

Objectives:

to analyze the characteristics of patients with ALS at the time of PEG/PRG placement, and to compare the efficacy and safety of PRG versus PEG.

Methods:

a retrospective descriptive study. All patients with ALS who required gastrostomy in the last 3 years (2021-2023) in our hospital were recruited (4 PEG and 6 PRG). Demographic and nutritional parameters were analyzed.

Results:

ten patients were included, with an average age of 57 years. All patients presented with dysphagia and received oral or tube supplements prior to gastrostomy placement. The average duration of enteral nutrition was approximately 50 months, with a mortality rate of 30 % at 12 months after gastrostomy. The success rate of PEG and PRG was similar, with no complications. All patients developed deterioration of respiratory function, even after nutritional support.

Conclusion:

gastrostomy should be indicated as soon as a patient is at risk of aspiration pneumonia or when weight loss begins. Although the nutritional benefit of gastrostomy is well established, there is currently a delay between diagnosis and placement of approximately 4 years. PRG appears to be safer than PEG in patients with ALS and respiratory failure.
