Abstract

Objective: Radiologically inserted gastrostomy placement may be performed in patients with dysphagia secondary to amyotrophic lateral sclerosis (ALS). This study assessed technical outcomes and complications related to gastrostomy placement in patients with ALS. Methods: A retrospective review of patients with ALS who underwent gastrostomy placement between 2021 and 2023 was performed. Patient demographics, medical history, ALS disease manifestations, survival, and post-procedural complications were obtained from the electronic medical record. Technical outcomes related to gastrostomy placement were obtained from operative notes and review of procedural imaging. Results: A total of 100 patients were included in the study. The mean duration of ALS diagnosis at time of gastrostomy placement was 1.3 +/−1.2 years. The mean slow vital capacity at time of gastrostomy placement was 54.0 +/−20.2% (range 10–155%). Technical success was 100%, with 91 placed using fluoroscopic guidance and 9 placed with computed tomography guidance. Eighty-three percent of gastrostomies were performed as outpatient procedures, while 17/100 patients were admitted following the procedure for monitoring. Post-procedural adverse events were noted in 21/100 patients (15 mild and 6 moderate or greater). Three patients developed respiratory failure after gastrostomy tube placement and died within 1-week post-procedure. Lower pre-procedural slow vital capacity was associated with higher risk of post-procedural respiratory failure (p = 0.0003*). Conclusions: Gastrostomy placement in patients with ALS has a high technical success rate and may be performed safely in the outpatient setting in appropriate patients. Patients with low slow vital capacity related to ALS should be admitted post-procedurally for airway monitoring and support.
