Gastric Electrical Stimulation for Gastroparesis: An In-depth Patient Guide
Introduction and Terminology
Gastric Electrical Stimulation (GES) is an innovative and increasingly utilized treatment for a condition known as Gastroparesis, a disorder that slows or stops the movement of food from your stomach to your small intestine. This procedure involves the surgical implantation of a device similar to a pacemaker in the abdomen. The device delivers mild electrical pulses to stimulate the muscles and nerves of the lower part of the stomach, promoting better digestion and easing symptoms.
According to recent statistics, Gastroparesis affects about 5 million people in the United States. With an increasing recognition of its benefits, GES usage has grown significantly in the past decade, offering a lifeline to patients who’ve not responded well to traditional Gastroparesis treatments.
Indications for Gastric Electrical Stimulation
The primary indication for GES is Gastroparesis, particularly when traditional treatments have not been successful. It is often recommended for patients with:
Chronic nausea and vomiting that hasn’t responded to medication.
Difficulty managing blood sugar levels due to Gastroparesis in diabetes.
Significant weight loss or malnutrition due to severe Gastroparesis.
Furthermore, GES may be considered in cases of chronic, intractable nausea and vomiting associated with conditions such as functional dyspepsia and cyclic vomiting syndrome.
It’s vital to note that GES may not be suitable for everyone. Certain health conditions, including some types of stomach surgery or stomach cancer, may make GES less effective or inappropriate. Therefore, each patient’s unique situation needs to be thoroughly evaluated by their healthcare provider to determine if GES is the most suitable treatment option.
Pre-Op Preparation
Preparing for a GES procedure involves several steps:
Fasting is typically required 8 to 12 hours before the procedure.
Pre-operative laboratory tests or imaging may be ordered to ensure you are in the best possible health for the surgery.
It’s necessary to arrange transportation to and from the hospital as you will be under anesthesia for the procedure.
Work or school absence notes can be provided, if necessary.
Keep in mind, your physician will provide detailed instructions customized to your health status, including any adjustments to your medications. Always consult your healthcare provider if you have questions about your pre-operative instructions. Your medical team will ensure you are well-prepared for your procedure.

Procedure Technique for Gastric Electrical Stimulation
The Gastric Electrical Stimulation (GES) procedure involves several key steps. While your medical team will handle all the technical aspects, understanding what happens during the procedure can help ease any concerns and set expectations. Let’s go through each step of the GES procedure, keeping in mind that your experience may vary slightly based on your specific health condition and the surgeon’s technique.
Step 1: Anesthesia
The procedure begins with the administration of general anesthesia, which puts you in a sleep-like state to ensure you don’t feel pain during the surgery. An anesthesiologist will be present throughout the procedure to monitor your vital signs and ensure your safety and comfort.
Step 2: Surgical Incision
Once the anesthesia has taken effect, the surgeon will make a small incision (a surgical cut) in your abdomen. This allows access to your stomach for the placement of the stimulator device.
Step 3: Placement of the Electrodes
The surgeon will then carefully insert two insulated wires, known as leads or electrodes, through the stomach wall. The ends of these electrodes have tiny spiral tips that are screwed into the muscular wall of your stomach to ensure secure contact.
Step 4: Implantation of the Neurostimulator
After the electrodes are in place, they are connected to a small, battery-powered device known as a neurostimulator, which is implanted under the skin of your abdomen. This is the ‘pacemaker’ device that will deliver electrical signals to your stomach.
Step 5: Testing the Device
Before the incision is closed, the neurostimulator is tested to make sure it’s working properly and delivering the correct level of stimulation. The settings may be adjusted for optimal function.
Step 6: Closing the Incision
Once the neurostimulator is functioning properly, the incision in your abdomen is carefully closed using sutures or surgical staples. This concludes the GES procedure.
Remember, the main goal of GES is to reduce the symptoms of Gastroparesis by stimulating your stomach muscles, improving their ability to contract and facilitating the movement of food. It’s a significant step towards managing Gastroparesis, but it’s important to know that it’s not a cure. The therapy’s effectiveness varies from patient to patient, and it works best in combination with dietary changes and medications as recommended by your healthcare provider.
Please note that this description is a general overview and may not reflect the exact steps taken during your procedure. Always consult your healthcare provider for the specifics about your GES procedure, including potential risks and benefits. Your medical team will provide you with information tailored to your unique health condition and treatment plan.

Duration of Gastric Electrical Stimulation
The Gastric Electrical Stimulation procedure generally takes about 2 to 3 hours, though this may vary depending on the specific circumstances of the patient.
Post-Op Recovery from Gastric Electrical Stimulation
Recovering from a Gastric Electrical Stimulation procedure involves several stages. Immediately after surgery, you will typically be observed in a recovery room for a few hours before being discharged home. It is recommended that someone accompanies you home after the procedure due to the effects of the anesthesia.
Post-operatively, you will need to follow up with your healthcare provider regularly. The schedule varies depending on individual circumstances, but often begins with a two-week follow-up appointment to check the surgical wound and device function, followed by regular appointments every 3 to 6 months.
No specific rehabilitation or physical therapy is typically needed, but lifestyle modifications, including diet changes, may be recommended. Time off from work can vary, but generally, patients are advised to take 1-2 weeks off to recover. Full recovery can take several weeks, depending on individual health and recovery response.
Our telemedicine primary care practice is available to provide same-day appointments until 9pm on weekdays and 5pm on weekends to ensure you have the necessary documentation for your work or school.
Effectiveness of Gastric Electrical Stimulation
Gastric Electrical Stimulation has been shown to be effective in managing the symptoms of Gastroparesis, especially in patients whose symptoms have not responded to conventional treatment methods. While it does not cure Gastroparesis, it significantly improves quality of life by reducing symptoms like nausea, vomiting, and abdominal pain.
Several studies indicate a reduction in Gastroparesis symptoms in about 70-80% of patients after GES. However, the effectiveness varies from patient to patient and depends on factors like the underlying cause of the Gastroparesis, patient compliance with dietary modifications, and the overall health of the patient.
One key factor influencing the effectiveness of GES is the presence of diabetes. Studies have shown that diabetic patients with Gastroparesis tend to respond well to GES. On the other hand, patients with Gastroparesis due to other causes may not experience the same level of symptom relief.
Also, it’s important to note that it can take some time to see the full effects of the GES procedure. Some patients may begin to see an improvement in symptoms within a few weeks, while for others, it may take several months. As always, individual experiences may vary, and it’s important to discuss your specific situation and expectations with your healthcare provider.
Adverse Events with Gastric Electrical Stimulation
Like any medical procedure, Gastric Electrical Stimulation (GES) carries a risk of complications. Below is a list of potential adverse events and their estimated occurrence:
- Infection (4%): Infections may occur at the surgical site or around the implanted device. This can typically be managed with antibiotics, but in rare cases, the device might need to be removed.
- Technical or device problems (6%): These might include issues such as lead dislodgement or device malfunction, requiring device adjustment or replacement.
- Pain at implant site (5%): Some patients may experience discomfort or pain at the site of the implanted device, often subsiding over time.
The mortality rate associated with GES is very low, less than 1%. This includes deaths associated with surgery and deaths due to underlying illness.
Alternatives to Gastric Electrical Stimulation
If you’re considering GES, it’s worth knowing there are alternative treatments for Gastroparesis. These can be categorized into dietary modifications, medications, and other procedures:
- Dietary modifications: Eating smaller, more frequent meals, and avoiding fatty and high-fiber foods can help manage symptoms.
- Medications: Drugs such as metoclopramide or erythromycin can help stimulate stomach muscles and control nausea and vomiting.
- Other procedures: In more severe cases, procedures such as gastric bypass surgery or a feeding tube can be considered.
Experimental or Emerging Technologies
Research is ongoing for new treatments for Gastroparesis. One promising technology is the use of gastric per-oral endoscopic myotomy (G-POEM). This procedure involves using an endoscope to cut the muscle at the junction between the stomach and small intestine, improving gastric emptying.
