What does the fundoplication wrap actually do?

The wrap reinforces the junction between your esophagus and stomach by folding the top of the stomach around the lower esophagus. This adds support to the lower esophageal sphincter, the valve that is supposed to keep stomach acid from leaking upward. When that valve is weak, acid reflux is more likely.

Who may be a candidate for fundoplication?

Candidates often include people whose GERD or hiatal hernia symptoms have not responded well to lifestyle changes and medicines. Your doctor and surgeon evaluate your specific anatomy, health history, and test results. This site provides general education only. Your surgeon decides whether this operation may be appropriate for you.

What are the most common side effects after fundoplication?

The most commonly reported side effects include difficulty swallowing in the early weeks, trouble burping, and feeling full quickly after small meals. These effects often improve over time for many people, though no outcome is promised. Discuss likely side effects with your surgeon ahead of time.

How do I verify a surgeon's license in California before GERD surgery?

You can check any California physician's license on the Medical Board of California website at mbc.ca.gov. Search by name or license number. This is a free public resource. Verifying credentials is a reasonable step before moving forward with any surgical procedure.

Fundoplication and GERD Surgery: What the Wrap Does

2026-11-06 · By Acid Reflux Surgery LA Editorial · General information, not medical advice

An educational overview of how fundoplication works, what wrap types exist, and the risks Los Angeles patients should discuss with their surgeon before considering GERD surgery.

Understanding GERD and Hiatal Hernia

GERD stands for gastroesophageal reflux disease. It happens when stomach acid flows back up into the esophagus, the tube that carries food from your mouth to your stomach. Over time, repeated acid exposure can irritate the esophagus lining and may lead to complications.

Many people with GERD also have a hiatal hernia. With this condition, the upper part of the stomach pushes through an opening in the diaphragm, the muscle that separates the chest from the abdomen. This can make it easier for acid to escape upward. Common symptoms may include heartburn, difficulty swallowing, a dry cough, bad breath, nausea, and breathing problems.

Without care, GERD can sometimes lead to serious complications, including esophagitis, esophageal stricture, and Barrett's esophagus, a condition in which the esophagus lining changes over time. Barrett's esophagus raises the risk of a type of cancer called esophageal adenocarcinoma.

When lifestyle changes and medicines do not control symptoms well enough, a surgeon may discuss additional options with you, including surgery.

Fundoplication: What the Wrap Does

Fundoplication is an operation that focuses on the lower end of the esophagus and the top of the stomach. A surgeon wraps the upper portion of the stomach, called the fundus, around the lower part of the esophagus. This creates a tighter junction between the two.

The goal of the wrap is to reinforce the lower esophageal sphincter, a ring of muscle that acts like a one-way valve. When that valve is weak, acid can leak upward. The wrap adds support to help keep it closed.

For many people who have a hiatal hernia along with GERD, the surgeon also repairs the hernia during the same operation, pulling the stomach back below the diaphragm and tightening the opening around the esophagus.

Today, many surgeons perform this operation laparoscopically, using small incisions and a tiny camera. This approach often means a shorter hospital stay compared to open surgery. Your surgeon decides the best approach based on your specific anatomy and health history.

Types of Fundoplication Wrap

The two most common versions differ in how much of the stomach wraps around the esophagus:

Nissen fundoplication (360-degree wrap): The fundus wraps all the way around the lower esophagus. This full wrap is one of the most widely performed approaches for GERD surgery in Los Angeles and across the country.
Partial wrap (such as Toupet or Dor): The fundus wraps only partway around, often between 180 and 270 degrees. A surgeon may choose this for specific reasons, such as concerns about swallowing difficulty after surgery.

Your surgeon decides which type fits your anatomy and overall health. No single approach is right for everyone, and no outcome is promised with either type.

Risks and Side Effects to Know

All surgery carries risks. Understanding them is part of making an informed decision. Possible risks and side effects of fundoplication may include:

Difficulty swallowing (dysphagia), which is often most noticeable in the first weeks after surgery
Gas bloating or difficulty burping, sometimes called gas bloat syndrome
Feeling full quickly after small meals
The wrap loosening or slipping over time, which may require a follow-up procedure
General surgical risks such as infection, bleeding, reaction to anesthesia, and injury to nearby structures

Talk with your surgeon about which risks apply most to your situation before making any decision.

Symptoms That Need Emergency Care

Some symptoms after abdominal surgery can signal a serious problem. Call 911 or go to the nearest emergency room right away if you experience sudden severe chest or abdominal pain, trouble breathing, high fever or chills, redness and warmth around incision sites, heavy bleeding, or vomiting that will not stop.

Checking Your Surgeon's Credentials in California

If you are exploring GERD surgery in the Los Angeles area, you have the right to verify your surgeon's California medical license. You can search any physician's license status on the Medical Board of California website at mbc.ca.gov. No link is needed. Simply type in the surgeon's name or license number.

Asking questions, reviewing credentials, and seeking a second opinion are all reasonable steps before any surgical procedure.
