Fundoplication is a surgical procedure in which the top of the stomach is wrapped around itself to prevent reflux. When the stomach is wrapped fully, it is referred to as a Nissen fundoplication (also called a Nissen, Nissen fundo, fundo, or just fundoplication). When the stomach is only partially wrapped, it is called a partial fundoplication.

This surgery is not required when getting a G-tube placed. It may be advised in instances when a child has severe reflux-related airway problems or when there is severe damage to the esophagus from reflux. Children who are aspirating secondarily (meaning they are aspirating their reflux) seem to be the best candidates for the Nissen. These children have likely had aspiration pneumonia, or are having breathing difficulties because of aspiration, or are turning blue.

Children who vomit a lot or who have delayed gastric emptying or gastroparesis are often not good candidates for a fundoplication. The fundoplication doesn’t address the cause of the vomiting, which is related to how slowly the stomach empties. In these children, fundoplication turns the stomach into a little pressure cooker. The contents of the stomach can no longer go up with a functioning fundoplication, and poor motility means they also cannot go down. Instead, you end up with a smaller stomach, and its contents don’t move in either direction. Kids in this situation tend to retch or have ongoing abdominal discomfort or pain. These children also tend to have more complications with vomiting past the fundoplication, the fundoplication slipping and needing to be redone, or the fundoplication herniating after it slips. A gastrojejunal tube (GJ-tube) may be an alternative to a fundoplication, or should be tried before moving forward with the procedure.

Children with neurological issues also tend to do much worse with Nissens, so these children should only receive a Nissen when the benefit clearly outweighs the risks. The GJ-tube would be a better alternative to consider.

Parents should discuss the procedure with their doctors and research the procedure before committing to a fundoplication. Note that the procedure cannot be reversed fully. Surgeons can only reconstruct the stomach as best as possible, but even this may result in additional nerve damage and complications. Few surgeons are willing to even attempt a fundoplication take down.

Common Question

Does every child with a G-tube need a Nissen fundoplication?

No!

In the past, almost every child receiving a G-tube also received a Nissen fundoplication. This is no longer standard of care. Fundoplication surgery should only be performed in children when the benefits outweigh the risks.

Burping and Vomiting

Fundoplications often inhibit a child’s ability to burp and vomit, at least temporarily. Many children require frequent venting for gas, as well as for stomach fullness that would lead to vomiting in a child without a fundoplication.

Conjunction with G-tube Placement

Some GIs and Surgeons are very pro-Nissen and will only do G-tubes in conjunction with them. This practice seems to be declining given the potential for complications in children who aren’t good candidates for the procedure. Many others are on the opposite camp and will only perform them under very specific circumstances. As a parent considering a Nissen Fundoplication, you should know that it isn’t a requirement to get one when getting a G-tube. That being said, reflux can often develop after the G-tube surgery, which is why some surgeons suggest them proactively.

The decision to get a Nissen Fundoplication is a big one. It is another surgical procedure and one that may have complications down the line, such as dumping syndrome, hiatal hernia, and even nerve damage. Be sure to ask your child’s doctor for details on potential complications and risk factors to help you make an informed decision.

Types of Fundoplications

There are different types of Nissen Fundoplications, including a complete wrap and a partial wrap. You should consult with a medical professional to better understand which they are recommending for your child and why.

Pros

  • No more aspiration from the stomach
  • For many, no vomiting from reflux, which can lead to better weight gain
  • Increased quality of life for you and your child
  • Often can be done laproscopically

Cons

  • When your child needs to throw up, he may retch, which is uncomfortable
  • The Nissen can slip, which can be dangerous and requires additional surgery
  • The Nissen can loosen and may need to be redone through additional surgery
  • Some children vomit through the fundoplication or continue to have reflux even after the procedure
  • Some have bloating problems where they need a lot of venting of the G-tube
  • Some children get dumping syndrome as a result, especially if they also have a pyloroplasty
  • Children with delayed gastric emptying/gastroparesis may end up using a GJ-tube even after having a fundoplication
  • Some surgeons will not perform these laproscopically
  • The surgery cannot be fully reversed; instead, the stomach must be reconstructed
