• Barium Meal

• Other tests:

What are the causes of gastroparesis?

Gastroparesis is literally paralysis of the stomach. The stomach loses its ability to contract when the nerves supplying electrical stimulation to the stomach muscles are damaged. Diabetes is the most common cause of gastroparesis. It is also seen in patients with nervous disorders such as stroke and Parkinson’s disease. Rarely, it can be a side effect of medication. Gastroparesis can be a complication of a surgery.

Do I need to have surgery?

In mild to moderate cases you could be treated with simple life style modification. Surgery may be more beneficial in severe cases and in patients who failed to respond with non-surgical treatment.

How is the surgery performed?

The gastric pacemaker (Gastric Electric Stimulation) placement involves insertion of two electrodes in to the front portion of the stomach muscles by laparoscopic method under general anaesthesia. These electrodes are connected to a pacemaker, fitted on top of abdominal wall muscles under the ribcage. The pacemaker generates very mild electric impulses which are transmitted to the stomach muscles via electrodes. These very mild impulses in turn stimulate stomach muscles to contract which helps in emptying its contents. Please consult your surgeon for further information on Gastric Pacmaker (GES) placement.

Do I need pre-operative assessment?

Yes, you will need assessment to ensure your fitness for surgery.

What is the recovery period?

You may need to stay 1-3 days following the surgery.

What do I expect following the surgery?

You will expect to see gradual improvement of your symptoms. It usually takes up to 6-12 months to notice significant improvement.

What is the aftercare?

You will need a regular follow up by your surgeon and the specialist nurse. The battery usually lasts for 5-6 years at which point it needs replacing.

Gastroparesis & Gastric Pacemaker

Gastroparesis is a condition where the stomach emptying is delayed. Normally, food we have eaten is digested partly in the stomach and emptied in to the small bowel for further digestion. This process usually takes 1-1 ½ hours, but it takes longer when you have gastroparesis.

Delayed stomach emptying could result in cumbersome symptoms. The gastroparesis can be treated with medication, life style modification, however some patients may benefit from having surgery.

At nu-life surgery we offer Gastric Pacemaker (Gastric Electrical Stimulation) placement to treat gastroparesis. We advise our patients to undergo various tests to confirm the diagnosis and also to ensure that the patient will benefit from the surgery. Please consult your surgeon for further information.
