GERDX: A Non-Surgical Option for Acid Reflux with a Small Hiatal Hernia

Chronic acid reflux paired with a hiatal hernia is one of the more frustrating combinations in digestive health. Medications can control symptoms for a while, but for patients whose hernia is small and who want to avoid full surgery, there’s a growing category of endoscopic options worth understanding — including a device-based procedure called GERDX.

A hiatal hernia occurs when part of the stomach pushes up through the diaphragm into the chest cavity, which can weaken the natural barrier against reflux. Larger hernias are usually best addressed surgically, since mesh or stitch-based repair is often needed. But for small hiatal hernias — generally those under a few centimeters — some patients are candidates for less invasive, purely endoscopic approaches that don’t require any external incisions.

GERDX is an endoscopic device used to perform a procedure sometimes described as endoscopic fundoplication. Working entirely through an endoscope (via the mouth, similar to a gastroscopy), the device places transmural sutures at the gastroesophageal junction. This reconstructs the gastric cardia — the area where the stomach meets the esophagus — creating a mechanical barrier that reinforces the lower esophageal sphincter (LES) and helps prevent reflux.

Because it works by suturing tissue into a reinforced fold rather than by creating a thermal injury (as ablation-based techniques do), GERDX is grouped with other “endoscopic plication” methods, alongside options like the Stretta procedure (radiofrequency-based) and transoral incisionless fundoplication (TIF).

Endoscopic approaches like GERDX are generally considered for patients who:

Larger hernias, complications like Barrett’s esophagus, or certain anatomical factors may steer a doctor toward surgical fundoplication instead — so proper endoscopic evaluation matters before choosing a path.

Dr. Kapil Sharma is a gastroenterologist and hepatologist based in Delhi-NCR, and the Founder and Director of GASTROQURE Liver, GI & Endoscopy Clinic in Kalkaji, New Delhi. He holds an MBBS from Government Medical College, Aurangabad, an MD in General Medicine from S.P. Medical College, Bikaner, and a DM in Gastroenterology from King George’s Medical University, Lucknow. With over two decades of practice, his work spans advanced endoscopic ultrasound, third-space endoscopy, and non-surgical anti-reflux procedures, and he has written and spoken publicly about non-surgical treatment options for acid reflux, including endoscopic fundoplication with GERDX, Stretta, TIF, and ARMA.

Gastroenterologists like Dr. Sharma typically evaluate candidacy for GERDX using upper endoscopy, pH monitoring, and esophageal manometry, to confirm both the reflux diagnosis and the size/type of hiatal hernia before recommending a specific endoscopic technique.

For patients with a small hiatal hernia and reflux that isn’t fully controlled by medication, GERDX offers a middle-ground option — more structural reinforcement than medication alone, without the incisions of laparoscopic surgery. As with any anti-reflux procedure, the right choice depends on your specific anatomy and reflux severity, which is best assessed directly by a gastroenterologist experienced in these techniques.
