The most common symptoms are nausea and protracted vomiting. Other symptoms include abdominal bloating, and, in severe cases, malnutrition. These NICE guidelines outline the procedural guidance for use of gastro-electrical stimulation.
Gastroparesis is a heterogeneous clinical syndrome. Gastric electrical stimulation (GES) has been proposed as an effective treatment option for patients with gastroparesis refractory to medical therapy. Evidence suggests that the clinically available device, a low-energy high-frequency GES, activates the vagal afferent pathways to influence the central control mechanisms for nausea and vomiting. Gastroelectrical stimulation Interest in electrical stimulation was driven by the knowledge…
