Long-term 10-year outcomes study1


This study examined the long-term (>10 years) safety and efficacy of Enterra Therapy in patients with intractable nausea and vomiting.


Retrospective, single-center French study examining 50 consecutive patients with refractory chronic nausea and/or vomiting lasting at least 12 months (failure of 2 prokinetics and antiemetics) implanted with gastric electrical stimulator.

Primary endpoint
  • Gastrointestinal Quality of Life Index (GIQLI) score.
  • Primary outcome was reduction in nausea and/or vomiting using a 5-point score.
  • Reduction in nausea and/or vomiting by 1 point, defined as >50% reduction in frequency.
  • In a retrospective study of 50 patients, Enterra Therapy significantly improved primary endpoint of nausea and vomiting in 54% of patients by greater than 50% at 10 years.
  • Enterra Therapy significantly improved primary endpoint of Gastrointestinal QOL Index (GIQLI) score and patients reported high level of satisfaction (80%) with the therapy at 10 years.
