Hello and a warm welcome to HealingWell. It is good to have you onboard. I am Kitt, your Moderator for this forum as well as a peer that has GERD.
Most GERD can be controlled through medications. In situations where medications aren't helpful or you wish to avoid long-term medication use, your doctor may recommend more invasive procedures.
Surgery to reinforce the lower esophageal sphincter is the Nissen fundoplication. This surgery involves tightening the lower esophageal sphincter to prevent reflux by wrapping the very top of the stomach around the outside of the lower esophagus. Surgery can be open, meaning the surgeon makes a long incision in your abdomen. Or surgery can be laparoscopic, meaning the surgeon makes three or four small incisions in the abdomen and inserts instruments, including a flexible tube with a tiny camera, through the incisions.
Esophyx is a trans oral incisionless endoscopic procedure that reconstructs the valve at the top of the stomach that helps prevents acid reflux.
I know you have had a chance to talk with several members re these procedures and I hope you find a surgeon that will evaluate you and help you decided what is your best option. The members here are really the best and know what they are talking about when it comes to their surgical experiences.
