There is insufficient scientific evidence on the short-term patient benefit of gastric pacing (Evidence grade 4). There is no scientific evidence on the long-term patient benefit of gastric pacing (Evidence grade 4). No scientific evidence is available on the cost effectiveness of the treatment (Evidence grade 4).
Gastric pacing is still an experimental method and should be used only in scientific studies that have been approved by a research ethics committee. Trials that include adequate control groups are very much needed.
