1 Guidance

1.1 Current evidence on the safety and efficacy of gastroelectrical stimulation for gastroparesis does not appear adequate to support the use of this procedure without special arrangements for consent and for audit or research.

1.2 Clinicians wishing to undertake gastroelectrical stimulation for gastroparesis should take the following actions.

  • Inform the clinical governance leads in their Trusts.

  • Ensure that patients understand the uncertainty about the procedure's safety and efficacy and provide them with clear, written information. Use of the Institute's information for the public is recommended.

  • Audit and review clinical outcomes of all patients having gastroelectrical stimulation for gastroparesis.

1.3 The procedure should only be performed in specialist gastroenterology units with expertise in gastrointestinal motility disorders.

1.4 Current evidence on the efficacy of the procedure relates mainly to relief from nausea and vomiting, which occurs in some patients. There is little evidence that the procedure improves gastric emptying. Further research will be useful, and the Institute may review the procedure upon publication of further evidence.
