Outcome of gastrostomy in parkinsonism: A retrospective study.

Objective: To investigate the indications and the outcomes of gastrostomy tube insertion in patients with parkinsonian syndromes.
Methods: Consecutive patients with Parkinson's disease or atypical parkinsonism, seen in two French tertiary referral movement disorders centers, that received gastrostomy tube insertion (GTI) for feeding between 2008 and 2014 were included in this retrospective study. Data regarding clinical status, indications and outcomes were retrieved from medical files. The main outcome measure was survival duration following gastrostomy insertion according to Kaplan-Meier estimate. Cox analysis was also performed to identify factors associated with survival. Finally, we described short term and long term adverse effects occurring during the follow-up period.
Results: We identified 33 patients with Parkinsonism that received GTI during the study period. One patient was excluded from the analysis because of missing data. Among 32 patients, 7 (22%) had Parkinson's disease and 25 (78%) had atypical parkinsonism. The median survival following the procedure was 186 days (CI 95% [62-309]). In Cox model analysis, total dependency was the only factor negatively associated with survival (HR 0.1; 95% CI [0.02-0.4], p = 0.001). Pneumonia was the most frequent adverse event.
Conclusion: In this sample of patients with parkinsonian syndromes, survival after GTI was short particularly in totally dependent subjects. Aspiration pneumonia was not prevented by GTI. A larger prospective study is warranted to assess the potential benefits of gastrostomy, in order to identify the most appropriate indications and timing for the procedure.
