Gastric Electrical Stimulation (GES)

Gastric electrical stimulation (GES) therapy has been developed as a treatment for patients with chronic gastroparesis, a disorder in which there is prolonged gastric retention following the ingestion of food in the absence of mechanical obstruction.

The implanted stimulator delivers electrical impulses to the gastric muscles with the objective of stimulating gastric myoelectric activity and, thereby, improving stomach emptying and reducing the frequency and severity of symptoms.

Direct electrical stimulation of the stomach (gastric stimulation) has been proposed as a treatment for obesity. This therapy requires the surgical insertion of an implantable gastric stimulator (IGS). Unlike bariatric surgery, gastric electrical stimulation is reversible, i.e., the device can be removed, and it does not change the anatomy of the stomach or gastrointestinal tract, or influence absorption of nutrients by the intestine.

The goal of the electrical impulses is to cause early satiety and reduce the appetite.

ODS can be caused by structural deformities in the rectum resulting in chronic constipation. A new surgical procedure, Stapled Transanal Rectal Resection (STARR), can treat ODS using minimally invasive methods.


What that means for most patients is a quick procedure and a short recovery time.

Gastric electrical stimulation (GES) utilizes an electrical device, Enterraâ„¢ Therapy, called a gastric pacemaker, to provide mild electrical stimulation to the lower stomach nerves.

Transmitted through a neurostimulator, these mild electrical pulses encourage the stomach to contract and help to relieve nausea and vomiting. Utilizing minimally invasive surgical techniques, the gastric pacemaker is placed subcutaneously below the rib cage in the abdomen. Two intramuscular lead wires with electrodes are implanted into the stomach muscle wall to deliver mild electrical pulses for symptom control.

This therapy is reversible and can be turned off at any time
