Pediatric Gastric Electrical Stimulation
Pediatric Gastric Electrical Stimulation (GES)
Overview
Gastric Electrical Stimulation represents an advanced therapeutic intervention for pediatric gastroparesis and related gastric motility disorders, utilizing electrical impulses to modulate gastric function.
Primary Indications
- Refractory gastroparesis
- Chronic nausea and vomiting
- Post-surgical gastric dysfunction
- Diabetic gastroparesis
- Neurogenic gastric dysfunction
Mechanism of Action
