What Is Heartburn, Acid Reflux, and GERD?

Heartburn is the burning discomfort behind the breastbone that happens when stomach contents flow backward (reflux) into the esophagus. When this reflux happens frequently or causes complications, it is called gastroesophageal reflux disease, or GERD.

GERD is extremely common. Roughly 20% of adults in the United States are affected, and in large surveys about 30% of people report reflux symptoms within any given week. It is one of the most prevalent digestive conditions in the Western world.

Typical symptoms include heartburn and acid regurgitation (a sour or bitter fluid rising into the throat). GERD can also cause less obvious or “atypical” symptoms: chronic cough, hoarseness, a sensation of a lump in the throat, frequent throat clearing, dental erosion, worsening asthma, and disrupted sleep.

What Causes Reflux?

At the junction of the esophagus and stomach there is a one-way valve called the lower esophageal sphincter, supported by the diaphragm muscle. When this barrier weakens or is disrupted, acid and stomach contents can escape upward.

A hiatal hernia is the most important mechanical cause. The esophagus normally passes through a small opening in the diaphragm called the hiatus. When that opening stretches and part of the stomach slides up into the chest, the anti-reflux barrier is weakened. Hiatal hernias are present in the large majority of patients with significant GERD, which is why reflux surgery and hiatal hernia repair are almost always performed together.

Other contributors include obesity, pregnancy, smoking, certain foods, and conditions that increase abdominal pressure.

Why Reflux Should Not Be Ignored

Beyond the discomfort, long-standing acid exposure can damage the esophagus. Possible complications include inflammation (esophagitis), narrowing (stricture), bleeding, and Barrett's esophagus — a change in the esophageal lining that carries a small but real risk of progressing toward esophageal cancer. Controlling reflux protects the esophagus over the long term.

How GERD Is Diagnosed

Before considering surgery, it is important to confirm the diagnosis and understand the anatomy. Testing commonly includes:

Upper endoscopy (EGD): a thin camera inspects the esophagus and stomach, measures the hiatal hernia, and checks for esophagitis or Barrett's esophagus.
Esophageal manometry: measures how well the esophagus squeezes. This is essential for choosing the correct type of fundoplication and for ruling out swallowing (motility) disorders.
Ambulatory pH or pH-impedance monitoring: the gold standard for proving acid reflux, with roughly 96% sensitivity and 95% specificity. It is often required when endoscopy is normal or only mildly abnormal.
Barium swallow (sometimes): an X-ray study used to map larger or more complex hernias.

Treatment Options — From Lifestyle to Surgery

Lifestyle and medication

First-line treatment includes weight loss, smaller meals, avoiding trigger foods, not eating before lying down, and elevating the head of the bed. Acid-reducing medications — especially proton-pump inhibitors (PPIs) — are highly effective for many people and remain the mainstay of medical therapy.

When medication is not enough

Medication does not work for everyone, and it does not fix the underlying mechanical problem. In large studies, roughly 17% to 32% of patients have only a partial response to PPIs, and over half of daily PPI users report persistent reflux symptoms. PPIs also reduce acid without stopping the physical backflow of stomach contents, so regurgitation can continue. Because they must be taken indefinitely, some patients prefer a durable solution.

Who Is a Candidate for Anti-Reflux Surgery?

Surgery is considered for patients with objectively confirmed GERD who have one or more of the following:

Symptoms that persist despite optimized medication, or only partial relief;
Good control on medication but a desire to stop taking lifelong pills;
A sizeable hiatal hernia;
Regurgitation, aspiration, chronic cough, or hoarseness (reflux-related respiratory symptoms);
Complications such as severe esophagitis, stricture, or Barrett's esophagus.

Anti-Reflux Surgery: What It Is

The most established and best-studied anti-reflux operation is a fundoplication. The upper part of the stomach (the fundus) is wrapped around the lower esophagus to rebuild the one-way valve so stomach acid can no longer flow back up. A full 360-degree wrap is called a Nissen; a partial 270-degree wrap is called a Toupet. Dr. Rafael A. Lugo, MD selects a Nissen or a Toupet for each patient based on esophageal function measured on manometry — a weaker esophagus generally does better with a partial wrap, which lowers the chance of long-term swallowing difficulty.

The operation has three core steps: the hernia is reduced (the stomach is returned to the abdomen), the diaphragm opening is repaired, and the wrap is constructed. It is performed entirely from inside the abdomen through small incisions — there is no large incision and no need to open the chest.

Repairing the Hiatal Hernia — and Why This Practice Does Not Use Mesh

The stretched diaphragm opening is closed with sutures, a step called a cruroplasty. In this practice, the repair is performed with a careful, tension-appropriate suture technique and without permanent mesh.

This is a deliberate, evidence-based choice. Some surgeons add mesh at the hiatus to reduce early hernia recurrence, and certain studies do show lower short-term recurrence with mesh (for example, one randomized trial reported about 8% recurrence with mesh versus 26% without, at one year, for very large hernias). However, the picture is more nuanced than that single number suggests:

Long-term durability is similar. More recent analyses find that, over the long term, recurrence rates with mesh and with suture repair alone are not significantly different, and mesh does not meaningfully reduce the larger, clinically important recurrences.
Mesh at the esophagus carries unique risks. Synthetic mesh placed next to the esophagus can erode into it, cause scarring and narrowing, and lead to chronic, difficult-to-treat swallowing problems. These complications can be serious and hard to reverse.

For these reasons, Dr. Rafael A. Lugo, MD prioritizes a meticulous suture cruroplasty and a properly constructed wrap to hold the repair, avoiding the long-term hazards of mesh at the hiatus. The durability of the repair comes from technique — a tension-free closure and the right wrap — not from a mesh implant.

Robotic, Laparoscopic, or Open?

Dr. Rafael A. Lugo, MD performs this surgery using a robotic platform, an advanced form of minimally invasive surgery. The surgeon controls every movement in real time from a console, with magnified three-dimensional vision, wristed instruments that bend like a human wrist, and tremor filtering — advantages that are especially valuable in the tight space around the diaphragm where the suturing is performed.

Compared with traditional laparoscopy, robotic hiatal hernia repair shows very low rates of conversion to open surgery (often under 2%, with some series reporting none) and hospital stays and complication rates that are similar to — and by some measures better than — standard laparoscopy. The robot does not operate on its own; it is an extension of the surgeon's hands and eyes.

How Successful Is the Surgery? (The Numbers)

Fundoplication is one of the most effective and durable operations in surgery for this problem.

Symptom control: roughly 85% to 95% of well-selected patients have good control of reflux symptoms in the years after surgery.
Freedom from medication: the large majority of patients are able to stop their daily acid-reducing pills.
Satisfaction: about 90% of patients report being satisfied with their decision to have surgery.
Durability: results are well documented for years, with a substantial share of patients still symptom-free a decade or more later.

The classic heartburn and regurgitation are usually gone immediately — many patients notice the reflux is gone the day they wake up from surgery. Outcomes are best when the diagnosis was confirmed with testing and the right wrap was chosen, which is exactly why the pre-operative work-up matters so much.

Risks and Side Effects (With Real Percentages)

Robotic and laparoscopic anti-reflux surgery is considered very safe in experienced hands. It is helpful to separate the expected, usually temporary side effects from the uncommon serious complications.

Common, usually temporary side effects

Difficulty swallowing (dysphagia): very common in the first weeks because of swelling around the new wrap; it improves for most patients within about 3 to 12 weeks. Persistent dysphagia that needs treatment is uncommon — many series report only about 2% to 5%.
Gas-bloat and reduced belching: because the valve is tightened, air is harder to burp up; bloating and increased flatulence are common early and usually ease over the first months.
Inability to vomit: the wrap makes vomiting difficult — this is expected.

Uncommon serious complications

Risk of death: very low, about 0.1% to 0.2% (roughly 1 to 2 in 1,000).
Overall serious-complication rate (30 days): on the order of 3% to 4%.
Injury (perforation) of the esophagus or stomach: under 1% (about 0.9%), repaired during the same operation when recognized.
Spleen injury: under 1% with the minimally invasive approach.
Conversion to open surgery: rare — often under 2% with the robotic approach.

Can reflux come back?

No anti-reflux repair lasts forever in every patient. Over the long term, roughly 10% to 20% of patients eventually have some return of reflux symptoms or need acid medication again, and a smaller share — commonly cited around 3% to 13% — undergo a second (revision) operation. Recurrence is more likely with very large hernias. If symptoms return, they are re-evaluated with testing, and a revision repair can be performed when needed — the robotic platform is particularly well suited to this precise, scarred-tissue surgery.

What to Expect: Recovery and Diet

Most patients stay one night, and many go home the same day or after a short overnight observation. Because the incisions are small, pain is usually modest and well controlled with non-narcotic medication. Most people return to desk-type work in about one to two weeks; walking is encouraged right away, but heavy lifting (generally over 20–30 pounds) is avoided for several weeks to protect the repair.

Because the wrap is swollen at first, the diet advances gradually: clear liquids for the first day, full liquids for several days, soft foods for about two to six weeks, then a return to a normal diet over four to eight weeks. Eating small portions slowly, chewing well, and avoiding carbonated drinks and dry or tough foods early on makes this phase much easier. A feeling of tightness when swallowing in the first weeks is normal and typically eases over 3 to 12 weeks.

The Bottom Line

For the right patient, robotic anti-reflux surgery with a suture-based hiatal hernia repair offers durable freedom from reflux and from lifelong medication, with a high success rate and a low risk of serious complications. The keys to a good outcome are careful patient selection, thorough pre-operative testing, choosing the correct wrap for each esophagus, and a meticulous, mesh-free repair.
