Information for the public
In this procedure, low-energy electrical impulses are applied to the sphincter (the ring of muscle separating the oesophagus from the stomach). The aim is to strengthen the muscle so that less reflux happens.
While the patient is under a general anaesthetic, 2 small electrodes are put into the sphincter using keyhole surgery. They are connected with a lead to a stimulator, which is placed under the skin of the abdomen and programmed wirelessly. The stimulator sends regular impulses to the sphincter to tone it up and improve its effectiveness. The patient should not feel the stimulation.
