BackgroundPercutaneous endoscopic gastrostomy (PEG) tube placement in amyotrophic lateral sclerosis (ALS) patients with impaired respiratory function is associated with an increased risk of peri-procedural and post-interventional complications. It was the aim of the study to analyze peri- and post-interventional complications and survival after PEG tube placement under noninvasive ventilation (NIV) in ALS patients with various degrees of respiratory impairment.MethodsTwenty-six subjects were included in this retrospective case study. Prior to PEG tube placement, training with ventilatory support via an oronasal mask was performed with ALS subjects on the pneumology ward. PEG placement was then performed under continuous NIV. FVC, sniff nasal inspiratory pressure, and demographic data were assessed. Complication rates and 1-month and overall survival rates were analyzed.ResultsThere were no deaths within 24 hours after PEG placement. One subject died within the first month. The mean survival rate after PEG was 12 ± 10 months (range 0.6-42 months). There was no difference in post-PEG survival between subjects with moderately (> 50%) and severely (< 50%) impaired FVC.ConclusionsIn this case series, PEG tube insertion was associated with minimal peri- and post-procedural complications. The low complication rate might be due to the systematic use of procedural NIV in ALS subjects.
