What Is Fundoplication Surgery?

The problem the operation fixes

Heartburn that keeps coming back, year after year, usually traces to one weak point: the ring of muscle at the bottom of the food pipe (oesophagus) that is supposed to keep stomach acid where it belongs. Fundoplication is the operation designed to reinforce that weak point — not with a device, but with the stomach itself. This article follows the procedure step by step.

Start with the short guide at the top of this page, "Anti-reflux Surgery," which runs just over a minute. It is a fundoplication guide for gastroesophageal reflux disease (GERD), and its description sums the operation up in one sentence: during fundoplication surgery, the upper curve of the stomach (the fundus) is wrapped around the oesophagus and sewn into place. Everything below is that sentence, unpacked. If you want the background first, our explainer on acid reflux and GERD covers why the valve fails and what reflux does over time. And if you'd rather watch the operation itself, the recording "Nissen Fundoplication", about three and a half minutes long, shows a real laparoscopic case.

Step one: confirming surgery is the right answer

Fundoplication is not a first response to heartburn. Most people reach it only after acid-reducing medicines and lifestyle changes have failed to control symptoms, or because they would rather not depend on daily medication for decades. Before anyone is booked in, the diagnosis is usually re-checked with tests — typically a camera examination of the food pipe (endoscopy), a measurement of acid in the oesophagus over 24 hours, and a pressure test (manometry) that shows how well the food pipe squeezes. That last test matters: the wrap tightens the valve, so the pipe above it needs enough strength to push food through.

Weight is part of the conversation too, because it affects both reflux and surgical planning — you can check your own figure with our BMI calculator.

Step two: the operation itself

The operation is almost always keyhole (laparoscopic) surgery under a general anaesthetic, through several small cuts in the abdomen rather than one large one. Working from the camera view, the surgeon first frees the top of the stomach (the fundus) and the lowest part of the food pipe. If a hiatus hernia is present — part of the stomach sliding up through the diaphragm, a common companion of stubborn reflux — it is pulled back down and the opening in the diaphragm is tightened with stitches.

Then comes the wrap, the step the whole operation is named for. The fundus is folded around the lower food pipe and stitched to itself, forming a snug cuff. In a complete wrap, called a Nissen fundoplication, the stomach goes the full circle; partial wraps cover only part of the circumference and are sometimes chosen when the food pipe's squeezing is weak. The new cuff acts as a reinforced one-way valve: food passes down, but acid finds it much harder to travel back up.

Step three: the first days of recovery

Most people are up and about quickly, but eating changes for a while. Because the valve area is swollen and the wrap is snug, food goes down slowly at first, so soft foods and small mouthfuls are the usual pattern in the early weeks, with solid food returning gradually. Heavy lifting is avoided while the small incisions heal.

Two side effects are worth knowing about before, not after. Swallowing can feel tight early on, and the tightened valve makes it harder to burp or be sick, so swallowed air can leave you feeling bloated — often called gas-bloat. For most people these ease as healing settles; for a minority they linger, and a small number eventually need a further procedure. Reflux surgery trades one set of problems for a much smaller one, and a good pre-op conversation makes that trade plainly.

Frequently Asked Questions

Is fundoplication the same as Nissen fundoplication?
Not quite. Fundoplication is the general operation — wrapping the top of the stomach around the lower food pipe. A Nissen fundoplication is the best-known version, in which the wrap goes the full 360 degrees. Partial wraps also exist and are sometimes preferred when the food pipe's own squeezing is weak.

How long does recovery from fundoplication take?
Recovery varies, but the pattern is usually a short hospital stay, soft foods and small mouthfuls for the first weeks while swelling settles, and a gradual return to a normal diet. Heavy lifting is typically avoided early on. Your surgical team will give you a timetable matched to your case.

Can reflux come back after fundoplication?
It can. Most people get lasting relief, but wraps can loosen or slip over the years, and some people eventually return to acid-reducing medicine or need a further procedure. That possibility is part of the decision, not a reason on its own to avoid the operation.

Will I still be able to burp after the surgery?
Often not easily, at least at first. The reinforced valve that blocks acid also resists air travelling upward, which is why bloating after meals is a common early complaint. For many people this improves as healing settles.
