A New Way to Treat Acid Reflux With LINX®

If you have gastroesophageal reflux disease (commonly known as acid reflux or GERD), there’s a less invasive surgical treatment that can help. The LINX® Reflux Management System can get rid of the symptoms caused by GERD. 

This system uses a small, flexible band of titanium magnets that are surgically implanted around the outside of your Lower Esophageal Sphincter (LES), which helps prevent stomach acid from entering your esophagus. These titanium beads are designed to open and close to let food down and back up. This minimally invasive solution allows many patients to return home the day of surgery and resume a normal diet shortly after the procedure.

We’ll help you find a permanent solution, so you can stop relying on antacid medications and find lasting relief.

Minimally Invasive Treatments

Living your best means feeling your best — inside and out. Our digestive health specialists are here to help you heal faster and experience less pain as you recover using the latest technology and minimally invasive techniques, which include:

  • Biopsy
  • Colonoscopy
  • Endoscopy
  • Fluoroscopy
Prevention for Peace of Mind

You’re feeling good, strong and healthy. And we want to keep you that way with preventive health care.

Colonoscopy screenings are recommended after you turn 50, or sooner if you have risk factors, including a family history of colon cancer. The procedure is short, simple and painless and can bring peace of mind that you’re not at risk for colon cancer.

If you're over 50 or have risk factors, put "schedule a colonoscopy" on your to-do list. It's the best way to find issues and treat them early.
