What is the magnetic sphincter augmentation (MSA) device for gastroesophageal reflux disease (GERD)?
The magnetic sphincter augmentation (MSA) device (also known as Linx Reflux Management System) is a small ring of magnetic beads. It helps keep acid in your stomach. It's used to treat gastroesophageal reflux disease (GERD). GERD is the backward flow of stomach acid into the esophagus, the tube that carries food and liquid to your stomach.
How can the magnetic sphincter augmentation (MSA) device help with gastroesophageal reflux disease (GERD)?
The MSA device is placed around the base of the esophagus where it meets the stomach. The device helps keep the lower esophageal sphincter (LES) closed. That's the valve between your stomach and esophagus. It helps stop food from going back up into the esophagus.
The device keeps the valve closed when you aren't eating. When you swallow, it allows the valve to open so food can pass through. This helps keep stomach acid out of the esophagus.
Your doctor might suggest getting the device if other treatments haven't helped your symptoms. Some people with GERD may be helped by a device. Others may need different types of surgeries.
How is the magnetic sphincter augmentation (MSA) device inserted?
You will need a minor surgery to insert the MSA device. You will be asleep during the surgery. You will be kept comfortable and safe by your anesthesia provider.
Your doctor will make a few small cuts (incisions) in your belly. The doctor will use special tools to insert the device through one of the cuts and attach it around your lower esophagus. A thin, lighted tube, or scope, in another cut will allow the doctor to see inside your belly.
It takes about 30 minutes to an hour to place the device. You may be able to go home the same day or the next day.
What are the side effects of the magnetic sphincter augmentation (MSA) device?
After getting an MSA device, some people have trouble swallowing. This may last up to a few weeks. You may also have pain in the chest, vomiting, or nausea.
