Fundoplication for Reflux

The barrier between the esophagus and the stomach is partly muscular and partly anatomic. When that barrier fails, stomach contents move up. Medication reduces the acidity of what comes up. It does not restore the barrier.

A fundoplication addresses the barrier directly. The upper portion of the stomach, the fundus, is wrapped around the lower esophagus and secured, which reinforces the valve mechanism at that junction.

A complete wrap, commonly called a Nissen, encircles the esophagus fully. A partial wrap, such as a Toupet, covers part of the circumference. Current evidence shows the two give broadly similar reflux control, with partial wraps generally causing less difficulty swallowing, bloating, and trouble belching, which is why manometry findings weigh heavily in the choice.

The usual candidates are people with objectively documented reflux who either do not respond adequately to medical treatment, cannot tolerate the medication, or do not want to remain on acid suppression indefinitely.

Regurgitation that persists on medication is a particular reason, because acid suppression changes the acidity of refluxed material without preventing the reflux itself.

It is also considered alongside hiatal hernia repair, since restoring the anatomy at the hiatus and reinforcing the barrier are related problems.

This is not an operation offered on symptoms. Endoscopy documents the lining and any hernia. pH or impedance testing establishes that reflux is real and that it correlates with what you feel.

High resolution manometry may be recommended before an antireflux operation. It excludes achalasia and other major motility disorders and characterizes how the esophagus moves, which directly influences the choice of wrap. Findings are reported using the current Chicago Classification, version 4.0 from 2021. A complete wrap placed on an esophagus that moves poorly can cause persistent difficulty swallowing, and manometry is how that risk is identified before rather than after.

Imaging is added when anatomy needs to be seen in motion, particularly with a large hernia or after prior surgery.

The operation is typically done through small abdominal incisions, and hospital stay depends on the procedure and your recovery. Diet advances in stages from liquids through soft foods over several weeks while swelling settles.

Common early effects include tightness with swallowing, bloating, and difficulty belching or vomiting. Most of these improve over the first months. Some people find bloating persists to a degree.

Reflux control is generally good, and it is not permanent in everyone. Wraps can loosen or slip over time, and a portion of people resume medication years later. That honest tradeoff belongs in the decision, not after it.

This page is educational information, not medical advice. What is right for you is decided in consultation, after a review of your history, your symptoms, and your testing.

Medication reduces acidity and is often the starting point. It is effective for burning and less effective for regurgitation.

Hiatal hernia repair addresses position and the size of the opening. Fundoplication addresses the barrier itself.

A LINX device is an alternative for restoring the valve. It is a small ring of magnetic beads placed around the lower esophagus instead of a wrap.

Which of these is appropriate for a given person depends on testing, on how the esophagus moves, and on what the person is trying to achieve. That determination is made in consultation.
