Anti-reflux surgery is a minimally invasive procedure designed to treat gastroesophageal reflux disease (GERD) by restoring the function of the lower esophageal sphincter. Chronic reflux can cause heartburn, regurgitation, chest discomfort, cough, aspiration, and damage to the esophagus. Surgical options include fundoplication (Nissen, Toupet, or Dor) and the LINX magnetic sphincter augmentation device. These procedures reduce reflux, improve symptoms, and protect the esophagus from long-term complications.

GERD occurs when the valve between the esophagus and stomach becomes weak, allowing acid to flow upward. Anti-reflux surgery strengthens this valve. Fundoplication uses the upper part of the stomach to reinforce the valve, while the LINX device uses a ring of magnetic beads placed around the lower esophagus to restore barrier function. The choice of technique depends on reflux severity, esophageal motility, and anatomy.

Significant reduction in reflux. Improved heartburn and regurgitation. Better swallowing. Reduced cough and aspiration. Protection against esophagitis and Barrett’s esophagus progression. Minimally invasive approach with fast recovery. Durable long-term results.

Patients with GERD not controlled by medication. Patients with regurgitation, aspiration, chronic cough, or laryngopharyngeal reflux. Patients with hiatal or paraesophageal hernias requiring repair. Patients with intolerance to acid-suppressing medications. Patients with objective evidence of reflux on testing.

The procedure is performed laparoscopically or robotically. Small incisions are made in the abdomen. If a hiatal hernia is present, it is repaired first. For fundoplication, the stomach is wrapped around the esophagus in a full or partial configuration. For LINX, a magnetic ring is placed around the lower esophagus. The procedure typically takes one to two hours and patients go home the same day or next day.

Temporary difficulty swallowing. Gas bloating. Inability to vomit in some fundoplication patients. Rare risks include bleeding, infection, or injury to surrounding organs. LINX is not recommended for patients with severe esophageal motility disorders or metal allergies.

Timeline Most patients resume light activity within a few days. Soft diet for one to two weeks. Swallowing improves gradually as swelling resolves. Full recovery typically occurs within two to four weeks. LINX patients often resume normal diet sooner.

Most patients experience long-lasting relief of reflux and regurgitation. Medication use is significantly reduced or eliminated. Fundoplication and LINX both provide durable results when combined with healthy lifestyle habits and follow-up care.
