DEAR DR. ROACH: I am a 78-year-old female who has suffered from acid reflux for many years and has been taking Prilosec (omeprazole) for at least 15 years. I have heard that it is not meant for longtime use. I recently attended a seminar on the new LINX surgery and hope to have it done. Do you have any information on the success or problems after this surgery? — J.B.

ANSWER: The LINX device is a magnetic ring, placed by laparoscopic surgery, that helps increase the strength of the lower esophageal sphincter, the valve-like muscular structure at the junction of the esophagus and the stomach. This reduces reflux of stomach acid up into the esophagus. The procedure was very effective at reducing both heartburn symptoms (89% before procedure to 12% after) and the need for daily medicines like omeprazole (100% before to 15% after).

The device has not been in use for a very long time, so long-term safety data is unavailable.

There are other types of surgeries used to treat reflux, most of which are effective at reducing both symptoms and the need for medication. There are now options for treatment being done endoscopically, without the need even for laparoscopic surgery. My personal practice is to discuss medication treatments as well as surgical treatments for people with moderate to severe acid reflux.
