Deciding on Fundoplication: Surgery for Reflux in Children

Updated on February 2, 2012

Acid Reflux: Getting a Diagnosis (Our Story)

Our son has struggled with acid reflux for a very long time. At the age of nine months, he fell completely off the weight charts and by the age of two, he had difficulty swallowing food. Our pediatrician tried to convince us that the weight loss was a phase, and that he would soon begin eating again. Not convinced, we consulted his Ear, Nose, and Throat (ENT) doctor for a second opinion. Since he had a congenital hearing loss, his ENT was very attuned to his history and immediately referred him for some basic upper gastrointestinal testing. When the tests came back with “normal” results, we were rather stressed and at a loss for what could be causing his issues.

In the end, we were referred to a gastro-intestinal specialist (GI doctor) and an upper endoscopy with biopsy was performed, along with the placement of a 24 hour pH impedance probe. The results of the biopsy showed inflammation from chronic acid exposure, and the probe indicated severe acid reflux disease.

We finally had an answer, and started therapy with a proton-pump inhibitor medication (our son uses Nexium).

Certainly, most children have a more straight-forward diagnosis and more obvious symptoms: babies often arch their backs, have frequent vomiting, and may refuse to eat or cry frequently with pain. While our son refused food as he became a toddler, he had none of the “classic” signs of reflux! His primary signs were dysphagia (trouble swallowing), pulling at his neck, hiccups, coughing, and lack of growth.

Classic Signs of Reflux in Infants

  • Difficulty gaining weight
  • Excessive crying
  • Arching of the back after eating
  • Excessive vomiting*
  • Frequent waking from sleep

*Not all children with reflux will vomit, as some children have "silent" reflux, which may manifest as respiratory symptoms, coughing, or gagging.

Failing Medical Therapy for Reflux

Our little guy started growing after we initiated medical treatment for his reflux. At first, 10mg of Nexium (once per day) was enough to keep his growth in line. The effects of the medication started to wane, so he was put on the same dose, but twice per day. This worked well, but the effects of the medication started to decrease and we saw a resurgence of the coughing and refusal to eat. At this point, his dose of Nexium was doubled to 20mg per day, twice per day. His ability to eat food improved, but we started noticing other problems.

His sleep was extremely disturbed, and he often coughed and choked. A sleep study was performed and he was found to have severe obstructive and central sleep apnea. The acid reflux was the cause of the respiratory problems, and further testing found that he had laryngomalacia. More pH probe tests were performed, and the tests showed that the Nexium was no longer controlling the reflux adequately. Our little boy was put on an additional medication (an acid-blocking medication called Zantac) and surgery was performed on his airway to prevent it from collapsing while he slept.

Unfortunately, even the Zantac and Nexium could not keep the acid reflux at bay. His stridor (a loud noise made when trying to inhale through an obstruction) reappeared and the sleep apnea was still present. Our son’s diagnosis was changed from Gastro-Esophageal Reflux Disease (GERD) to Laryngo-Pharyngeal Reflux Disease (LPR) reflux. LPR is a different form of reflux, and results when both the upper esophageal and lower esophageal sphincters malfunction. By contrast, typical GERD involves the malfunction of only the lower esophageal sphincter. With the upper sphincter malfunctioning, our son’s airways were exposed to his stomach acid.

At this point, our ENT doctor requested that our son be evaluated for the anti-reflux surgery, or Nissen Fundoplication.

What is a Nissen Fundoplication?

A Nissen Fundoplication is a procedure that creates a tighter junction between the esophagus and the stomach. The top portion of the stomach (the fundus) is wrapped (“plicated”) around the esophagus, and stitched in place. When food enters the stomach, the wrap prevents any food or stomach acid from going up the esophagus.

The surgery can be performed laprascopically, which means several “keyhole” incisions are made in the patient’s abdomen. The recovery is much faster for this type of surgery than for an open fundoplication. In certain circumstances, the surgery cannot be performed laprascopically and the surgery is converted to an “open” fundoplication. Open surgery requires a longer hospital stay and recovery time.

Anxiety about the Fundoplication Procedure

As his parents, we were concerned about putting our son through another surgery, particularly when the first two surgeries for his airway were not successful (the first, a tonsillectomy and adenoidectomy, and the second, a supraglottoplasty). Our son does not have a good track record with surgical interventions, so we were quite reluctant to consider the surgery in the first place.

We researched the procedure, and found that the surgery is considered a "last resort" in the attempt to treat acid reflux. It is reserved for life threatening reflux complications, or for children who are failing medical therapy and face life-long medication and significant problems from the effects of reflux.

The Nissen Fundoplication surgery has significant side effects, and there are some contra-indications to the surgery. The side effects we read about included:

  • An inability to burp or vomit after the procedure.
  • Some children retch uncontrollably after the surgery.
  • Some children have trouble swallowing food after the surgery.
  • Food may get “stuck” in the esophagus, causing choking.
  • The fundoplication may come undone, requiring another surgery to redo the fundoplication.
  • The fundoplication may “slip,” creating a hiatal hernia.
  • Gas may build up in the stomach, causing a very painful condition called gas bloat.

We were also concerned about our son’s “motility,” since an earlier study had shown that his stomach emptied food too slowly. In children with delayed gastric emptying, problems like gas bloat can be increased after a fundoplication.

Fundoplication: Frequently Asked Questions

Before Choosing a Fundoplication: Things to Try

Usually, a child is only referred for a Nissen Fundoplication when they have severe, uncontrollable reflux that is impacting the child’s health. In some areas of the country, however, fundoplications are performed at a rather high rate. For instance, some hospitals will routinely perform a Nissen whenever a G-tube is placed, whether reflux has been identified or not. It is important to ask the following questions before consenting to a Nissen Fundoplication:

  1. Does my child actually have reflux? Many disorders masquerade as acid reflux. Eosinophilic Esophagitis, motility disorders, and even food allergies may be mistaken for acid reflux. pH probe testing should be performed to confirm the presence of reflux prior to surgery.
  2. Does my child have neurological problems? Studies have shown that fundoplications are less effective for children who have pre-existing neurological problems, such as cerebral palsy and seizure disorders.
  3. If my child already has a G-tube and does not eat orally, has a G-J Tube been tried? Some children do not take food by mouth, and in those instances, a G-J tube can be placed. This delivers food directly to the small intestine and prevents reflux. This is obviously not an option for children who take food by mouth, but may be a good option for children with neurological problems who already receive enteral nutrition (formula fed directly into the stomach).
  4. Have all medical options been exhausted? There are many proton pump inhibitors, and they may be combined with acid blockers to increase effectiveness. In addition, motility drugs (including Reglan and Erythromycin) may be beneficial in reducing the amount of reflux, particularly for children with motility problems.
  5. Does my child have motility problems? Children with delayed gastric emptying are susceptible to problems like gas bloat, which may worsen when a fundoplication is performed. Esophageal motility problems are more worrisome, as swallowing can be more difficult after a fundoplication, and any existing esophageal motility problem could be worsened.

In other areas of the country, hospitals are loathe to perform the procedure, and children who truly need surgical intervention may struggle with severe side effects from the acid reflux. For children who have lung damage or difficulty maintaining a clear airway, a fundoplication is nearly always indicated.

Apnea and Reflux

While the C-Pap could treat the physical obstruction creating apnea, its use increased our son's ear infections and sinus infections. Acid reflux is commonly associated with a condition called laryngomalacia, both of which can cause apnea.

Deciding Against the Surgery

Since we were able to keep our son’s weight up with the medications, we decided to see if we could treat his remaining symptom of sleep apnea with a less drastic measure. We consulted with a sleep neurologist and our four year old son was placed on C-Pap therapy, or continuous positive airway pressure, to keep his airways open at night. While the C-Pap would not stop the reflux from occurring, it might be able to treat the biggest symptom we had at the time, which was apnea caused by inflamed, floppy tissue near the voice box (laryngomalacia exacerbated by acid reflux). When using nasal masks, he developed congestion, so we switched to a full-face mask. With his breathing in check, we thought we had the reflux monster under control.

Back to Square One: Revisiting the Nissen Fundoplication

A few months passed after starting C-Pap therapy, and our son’s congestion continued to worsen. He also started choking when he drank fluids, which was a rather unwelcome development. He started getting ear infections that would last for 3-8 weeks, with ear tubes in place – antibiotics had little effect. His coughing increased, and our ENT doctor ordered a CT scan of his sinuses and cultures of his ears. The CT scan showed chronic sinusitis, induced by the acid reflux. The cultures of his ears showed a similar problem: Pepsin, a digestive fluid, was found in the infected material. Our son literally had stomach acid coming out of his ears, and the antibiotics couldn’t keep up with the amount of inflammation the acid was inducing.

Unfortunately, while the C-Pap effectively treats the sleep apnea, it also seems to worsen the effects of our son’s acid reflux. This time, we had little choice. With his larynx and lungs under attack, the potential side effects of a Nissen Fundoplication were less than the potential side effects from severe, uncontrolled airway reflux.

Hoarse Voice Caused by LPR Reflux

Damage Caused by Reflux

The LPR form of reflux (also known as extra-esophageal or "silent" reflux) has several negative effects on the airway. Our four year old son often has a hoarse voice. This is caused by acid damage to the vocal cords.

A Visit with the Pediatric Surgeon

At the age of four-and-a-half, we reluctantly booked an appointment with a pediatric surgeon. At the appointment we voiced our concerns about the possible side effects of the surgery.

He reassured us that his patients are often able to burp and even vomit once the healing process is complete, though it may be impossible during the recovery time right after surgery.

While we were concerned about our son’s delayed gastric emptying, he assured us that many times, the scans show a “false” delayed emptying time, because when food refluxes up the esophagus, it can appear as if it is taking longer to empty out into the intestines. Once the fundoplication prevents the food from going up, it tends to empty out the bottom much faster.

Since our son uses a C-Pap to breathe at night, a gastrostomy tube (G-tube) would be placed at the same time as the reflux surgery. This way, if air became trapped in his stomach, we could vent the trapped air before it became painful. Once he had fully healed from the surgery, the G-tube could be removed if he no longer needed it.

While we weren't thrilled with the idea of placing a G-tube, we did agree that it would be a good comfort measure, and we were reassured that it could be removed once healing was completed.

We were quite relieved by the information given to us by the surgeon, so we agreed to sign the consent form for the surgery. The surgeon was a tad concerned by the various other medical problems our son has had in the past, however, so he held off scheduling a date for the surgery until he could review all of his medical history and scans.

Medical Tests Performed Prior to Fundoplication

  • Upper GI Barium (X-Ray), to verify normal anatomy and to rule out the presence of hiatal hernia or intestinal malrotation.
  • Gastric Emptying Scintiscan, to determine if delayed gastric emptying is present.
  • 24 Hour pH Impedance Probe, to verify and quantify the amount of reflux present.
  • Esophageal and Antro-duodenal Manometry (rarely performed)- these tests are the “gold standard” for motility testing and can determine if motility problems are present, and whether they are due to muscular or nervous system dysfunction. For most children undergoing fundoplication surgery, these tests are not necessary.

Reflux Surgery Called Off

After going for a ride on the roller-coaster of major, life-altering decisions, it felt good to have this decision made. The reflux surgery would fix his problems with his airway and choking, and possibly even his gastric emptying time. He may even be able to discontinue his medications, and go on to have a typical childhood, free from stomach issues. I started to dream of a day when the reflux nightmare was entirely in our past.

A few days later, our phone rang. It was early evening when the pediatric surgeon called, putting the entire surgery on hold. As it turns out, our son’s delayed emptying looked like true gastroparesis, and not an artificial result as the result of reflux. There were some worrying signs on his other tests (esophageal biopsy and some possible esophageal motility problems), so the surgeon called a halt to the surgical procedure.

We were back on the roller coaster of indecision again. The surgeon requested more medical files and consulted with the Gastro-Intestinal (GI) team at the hospital. Since our son’s airway is involved, a Nissen Fundoplication was still in the cards, but other problems had to be ruled out prior to the surgery.

The Surgery is Scheduled

The surgeon received the rest of our son's medical records, including his pH probe monitoring results and his esophageal biopsy pathology report. Within days, he called to inform us that the pathology report showed something known as Barrett's Esophagus. This is a precancerous condition that is rarely found in adults, and is almost unheard of in children. The presence of the dysplastic cells in our son's esophagus made the decision clear: our son would have the Nissen Fundoplication performed, along with another esophageal biopsy. If the presence of the dysplastic cells persists, he will have serial biopsies to monitor the condition.

His surgery is currently scheduled for March 2012. Despite the concern for motility problems, the surgery must be performed. Preventing esophageal cancer from forming in our son's future is the ultimate goal.
