Who Repairs a Hiatal Hernia and How Is It Done?

Hiatal hernia repairs are performed by general surgeons and thoracic surgeons, with general surgeons handling the majority of cases. In a review of nearly 14,000 procedures at academic centers, general surgeons performed about 72% of repairs while thoracic surgeons performed the remaining 28%, with comparable outcomes between the two specialties.¹ The procedure itself typically involves pulling the stomach back into position, tightening the opening in the diaphragm, and often adding some form of anti-reflux wrap around the lower esophagus. But who specifically should do your repair, what the operation actually involves, and whether you even need one depends on several factors worth understanding.

Not Every Hiatal Hernia Needs Surgery

There are four recognized types of hiatal hernia. Type I, known as the sliding hernia, is by far the most common: the junction between the esophagus and stomach slides upward through the diaphragm’s opening. Type II is a true paraesophageal hernia, where part of the stomach pushes up alongside the esophagus. Type III combines features of both, and type IV involves large hernias where other organs can migrate into the chest.² The type matters because it strongly influences whether you need an operation at all.

Guidelines from the Society of American Gastrointestinal and Endoscopic Surgeons (SAGES) strongly recommend against repairing a type I sliding hernia unless it is causing reflux disease with symptoms.³ For people with a hernia that causes no trouble, the yearly risk of developing symptoms that would require repair is only about 1%, making watchful waiting a reasonable approach.⁴ Surgery becomes the right call when you have a paraesophageal hernia with obstructive symptoms, when acid reflux persists despite medication, or when a complication like gastric volvulus (the stomach twisting on itself) develops.

There is some debate about younger patients. Some researchers have suggested that even asymptomatic patients under 50 with paraesophageal hernias should be considered for elective repair, on the theory that operating before complications arise is safer than waiting.³ This remains a point of clinical judgment rather than a firm consensus.

Which Specialist Should You See?

If your primary care doctor or gastroenterologist tells you a hiatal hernia repair is warranted, you will typically be referred to either a general surgeon or a thoracic surgeon. Within academic medical centers, general surgeons perform the large majority of these operations. A study examining outcomes across both specialties found no meaningful difference in results between the two groups.¹

More important than the surgeon’s specialty title is their volume of experience. Hiatal hernia repair is a technically demanding procedure, and surgeons who do it frequently tend to have better outcomes and lower complication rates. If you are choosing between a thoracic surgeon who performs these operations regularly and a general surgeon who rarely does, the thoracic surgeon is the better bet, and vice versa. Many of the surgeons with the deepest expertise identify as foregut surgeons, a subspecialty within general surgery focused on the esophagus, stomach, and diaphragm.

What Happens Before the Operation

Before scheduling surgery, your team will want a clear picture of the hernia’s size, type, and the state of your esophagus. The three main diagnostic tools are a barium swallow X-ray, upper endoscopy, and high-resolution manometry (a test that measures pressure along the esophagus). Of these, the barium swallow detects hiatal hernias at the highest rate, picking them up in roughly three-quarters of cases.⁵ Because no single test catches every hernia, surgeons often use all three before committing to a plan.

Manometry is especially useful because it tells the surgeon how well your esophagus can push food downward. That information directly shapes the type of anti-reflux procedure the surgeon will perform: if your esophageal muscles are weak, a full wrap around the stomach may cause more swallowing problems than a partial one. Endoscopy, meanwhile, lets the surgeon visually inspect the lining of the esophagus for damage from chronic acid exposure and rule out other issues.

Risk factors that the surgical team will weigh include your age, body mass index, and hernia size. Obesity raises the risk of developing a hiatal hernia in the first place by increasing abdominal pressure, and research has shown that nearly a quarter of patients undergoing evaluation before weight-loss surgery are found to have a hiatal hernia.⁶ Other risk factors include multiple pregnancies, prior esophageal or stomach surgery, and advancing age.

Laparoscopic Repair, Step by Step

The standard approach today is laparoscopic surgery, performed through several small incisions in the abdomen. The surgeon inserts a camera and slender instruments, then works through a sequence that broadly follows these steps: the hernia sac is carefully dissected away from surrounding structures in the chest, the stomach and lower esophagus are pulled back into their proper position below the diaphragm, and the opening in the diaphragm (the hiatus) is narrowed by stitching the muscular pillars of the diaphragm (called the crura) closer together.

For most patients with associated reflux, the surgeon then adds an anti-reflux procedure. The most well-known is the Nissen fundoplication, where the top of the stomach is wrapped 360 degrees around the lower esophagus, creating a one-way valve that prevents acid from splashing upward. Long-term data show the Nissen fundoplication controls reflux symptoms effectively for over a decade in the vast majority of patients.⁷ Laparoscopic Nissen fundoplication provides similarly strong symptom control across the full spectrum of reflux severity, from mild to severe disease.⁸

The alternative is a partial fundoplication, most commonly the Toupet, which wraps the stomach only about 270 degrees around the esophagus. Partial wraps tend to cause less swallowing difficulty and less gas bloat afterward, and they may offer comparable reflux control, particularly in patients whose esophageal muscles do not contract strongly.⁹ The choice between a full and partial wrap is one of the most consequential decisions your surgeon makes, and it is guided largely by the manometry results obtained before surgery.

The Mesh Question

One of the more debated aspects of hiatal hernia repair is whether to reinforce the diaphragm closure with a piece of mesh. The idea makes intuitive sense: the crural muscles are under tension, and a mesh patch should keep things from pulling apart. But the longest-running randomized trial on this question tells a different story. At 13 years of follow-up, recurrence rates were 38% in the mesh group and 31% in the suture-only group, a difference that was not statistically significant. Worse, patients who received mesh had persistently higher scores for difficulty swallowing solids.¹⁰ The study’s authors concluded that routine use of permanent synthetic mesh in hiatal hernia repair for reflux disease is not supported.

That does not mean mesh is never appropriate. In patients undergoing a second operation for a recurrent hernia, selective use of biosynthetic mesh (a material designed to be gradually absorbed by the body, unlike the permanent synthetic mesh in the study above) may protect against early re-herniation.¹¹ The key distinction is between a first-time repair, where sutures alone appear to work just as well, and a redo operation on weakened tissue, where some form of reinforcement may genuinely help.

Robotic Surgery Versus Standard Laparoscopy

Robotic-assisted surgery has become increasingly available for hiatal hernia repair. The surgeon sits at a console and controls robotic arms that hold the instruments, gaining a three-dimensional view and more precise instrument movement. A systematic review comparing robotic and standard laparoscopic repair for large paraesophageal hernias found that the robotic approach may offer a lower rate of needing to convert to open surgery and shorter hospital stays, with some evidence of fewer long-term recurrences.¹²

The story is not entirely in the robot’s favor, though. One large study from the early years of robotic adoption, encompassing nearly 170,000 patients, found a higher rate of esophageal perforation and respiratory failure in the robotic group.¹² That likely reflects a learning curve rather than a fundamental flaw in the technology. A more focused comparison at a single institution found no statistically significant differences in hospital stay, complications, readmission rates, or mortality between robotic and conventional laparoscopic approaches.¹³ Cost remains a genuine downside of robotic repair, as the equipment and disposable instruments are more expensive. For most patients, the choice between robotic and standard laparoscopy matters less than the surgeon’s experience with whichever platform they use.

What Recovery Looks Like

Most patients spend one to three nights in the hospital after a laparoscopic hiatal hernia repair. Some high-volume centers have pushed the boundary further with enhanced recovery protocols and opioid-free anesthesia, enabling same-day discharge in selected patients. One study found that using an opioid-free anesthesia protocol was a strong predictor of being able to go home the same day.¹⁴ This is not universal, but it signals where the field is heading.

After surgery, you will typically follow a modified diet for several weeks, starting with liquids and gradually advancing to soft foods before returning to a normal diet. The fundoplication wrap needs time to settle, and eating solid food too early can cause significant discomfort. Most people return to desk work within one to two weeks and to more physical jobs within four to six weeks, though this varies by the size of the hernia repaired and the patient’s overall health.

Side Effects You Should Expect

Two side effects are common enough after fundoplication that your surgeon should discuss them before the operation: dysphagia (difficulty swallowing) and gas bloat. Dysphagia occurs because the new wrap around the lower esophagus is temporarily tighter than what your body is used to. For most people it improves over weeks to months as swelling subsides and the wrap loosens slightly. Gas bloat happens because the new valve makes it harder to belch: air that you swallow with meals gets trapped in the stomach, causing bloating, pressure, and increased flatulence.

Research confirms that both dysphagia and gas bloat are more pronounced in patients who had a hiatal hernia repaired alongside the fundoplication compared to controls, and that these symptoms persist at a similar level whether you are a year and a half or nearly six years out from surgery.¹⁵ This is one reason partial fundoplications have gained favor: they tend to produce less dysphagia and gas bloat while still controlling reflux reasonably well.⁹ If you had a full Nissen and are struggling with persistent swallowing problems, it is possible to convert it to a partial Toupet wrap, and this conversion can now be done robotically.¹⁶

Recurrence Is More Common Than You Might Think

One of the less-discussed realities of hiatal hernia surgery is that hernias come back at a surprisingly high rate. The 13-year randomized trial mentioned earlier found radiologic recurrence rates around 30 to 38% regardless of whether mesh was used.¹⁰ It is important to note that a radiologic recurrence (visible on imaging) does not always mean the patient is having symptoms again. Many recurrences are small and cause no trouble. But when symptoms do return, a second operation may be needed.

Risk factors for recurrence include being over 65, having a BMI above 25, and having a larger or more complex hernia at the initial repair. Type IV hernias (the largest, with other organs migrating into the chest) carry the highest odds of coming back.¹⁷ The pattern of recurrence also shifts over time. In the first year after surgery, the most common failure pattern is “telescoping,” where the stomach slides upward through the intact wrap. Over longer follow-up periods, the dominant pattern becomes the entire fundoplication apparatus migrating back into the chest, often through an anterior defect in the diaphragmatic closure.¹⁸

Revision surgery is feasible but carries higher risks than the initial operation. Intraoperative complications during redo procedures have been reported at roughly 20%, most commonly involving inadvertent perforations of the stomach or esophagus.¹⁸ Gastropexy, a technique where the stomach is sutured to the abdominal wall to help anchor it in place, has been reported to reduce recurrence and is considered especially useful for patients at higher risk.¹⁷

When It Cannot Wait

Most hiatal hernia repairs are scheduled electively, giving you time to complete a workup and choose a surgeon. But some situations demand emergency surgery. Acute gastric volvulus, where the stomach twists on itself inside a large paraesophageal hernia, cuts off blood supply and can cause tissue death within hours. This is a surgical emergency.¹⁹ Patients typically present with sudden severe chest or upper abdominal pain, retching without the ability to vomit, and inability to pass a tube into the stomach. Emergency repair can sometimes still be performed laparoscopically, though the surgeon may need to convert to an open incision depending on the severity.²⁰

Strangulation, where blood flow to a portion of the herniated stomach is cut off without full volvulus, and incarceration, where the hernia becomes stuck and cannot be reduced, are also urgent indications. These emergencies are uncommon in people with small sliding hernias but become a real concern with larger paraesophageal hernias, which is part of the rationale some surgeons cite for recommending elective repair before an emergency forces the issue.

Less Invasive Alternatives

For patients with a very small hiatal hernia (under about 2 cm) and reflux symptoms, a newer option called transoral incisionless fundoplication (TIF) exists. This procedure is performed through the mouth using a device called EsophyX, which creates a partial wrap at the junction of the esophagus and stomach without any external incisions.²¹ Some surgeons combine a laparoscopic hernia repair with a TIF procedure rather than a traditional surgical fundoplication. TIF is not suitable for larger hernias or for patients with severe reflux, but it fills a niche for people who want to reduce medication dependence without committing to a full surgical wrap.

Hiatal Hernia Repair in Children

Hiatal hernias in children can be congenital, arising from developmental abnormalities, or acquired. Acquired pediatric hiatal hernias most often develop after prior anti-reflux surgery: one of the more striking findings in the pediatric literature is that aggressive dissection around the esophagus during a Nissen fundoplication can itself create a hiatal hernia. Modifying the surgical technique to minimize circumferential dissection has been shown to cut the rate of acquired hiatal hernias from roughly 37% down to about 12%.³ Pediatric repairs follow the same general principles as adult repairs: reducing the hernia, closing the crura, and adding an anti-reflux procedure, typically performed laparoscopically. Pediatric surgeons handle these cases, and the laparoscopic approach is considered safe and effective in this population.
