Gastroelectrical stimulation for gastroparesis

The procedure

The procedure is carried out with the patient under a general anaesthetic. It can be done through a cut in the abdomen, or using keyhole surgery. A stimulating device (similar to heart pacemaker) is put into a small pocket made under the skin of the abdomen. When the stimulating device is turned on, it sends electrical impulses to the stomach muscles that help them to work more normally. The amount of stimulation can be adjusted to suit the patient. Patients may need to go back to hospital after the procedure to adjust the device.
