Failed Fundoplication
Videos
Overview
Fundoplication — most often a Nissen (complete) or Toupet (partial) wrap — is the standard operation for gastroesophageal reflux disease and is usually part of hiatal hernia repair. Most patients do very well for many years. But a minority develop symptoms again, or develop new problems such as trouble swallowing or bloating, because the wrap has slipped, come apart, become too tight, or herniated back into the chest. This is called a failed fundoplication.
Recurrent or new symptoms after anti-reflux surgery do not always mean the operation failed, and not every failure needs another operation. The key is a thorough evaluation that answers two questions: what exactly went wrong anatomically, and is it causing the symptoms? When a mechanical problem is confirmed, redo (revisional) anti-reflux surgery can restore good function in most patients, with about eight in ten reporting a successful outcome in pooled studies (Furnée et al., Journal of Gastrointestinal Surgery, 2009). Because redo surgery is technically demanding, outcomes depend heavily on the surgeon's experience with reoperative foregut surgery.
Causes
The most common patterns of failure are well described (Hunter et al., Annals of Surgery, 1999):
- Wrap herniation: the wrap and part of the stomach move back up into the chest through a hiatus that has reopened. This is the most common cause of failure.
- Slipped wrap: the wrap slides down onto the stomach, creating a pouch of stomach above it that traps acid and food.
- Disrupted or loosened wrap: sutures pull through and the wrap comes apart, allowing reflux to return.
- Wrap too tight or too long: causes persistent difficulty swallowing.
- Twisted or malpositioned wrap: built around the stomach instead of the esophagus, or rotated.
- Unrecognized short esophagus that pulls the repair upward under tension.
- Wrong original diagnosis: a motility disorder such as achalasia, or gastroparesis, that was not identified before the first operation.
- Vagus nerve injury, which can slow stomach emptying and cause bloating and nausea.
Risk Factors
- Obesity, which raises abdominal pressure on the repair
- Large or paraesophageal hiatal hernia at the first operation
- Short esophagus from chronic inflammation
- Early heavy lifting, retching or vomiting after the original surgery
- Chronic cough or straining
- Incomplete preoperative testing before the first operation
- Previous redo operations
Who It Affects
Failed fundoplication can occur months to decades after the original surgery. Patients with a large hiatal hernia, obesity, or a short esophagus at their first operation have a higher risk. Many patients searching for help have already seen several doctors and have been told that "nothing more can be done" — which is often not the case.
Complications
- Recurrent erosive esophagitis and Barrett's esophagus from persistent reflux
- Food impaction from a tight wrap
- Gastric volvulus or obstruction from a herniated wrap
- Malnutrition and weight loss
- Aspiration pneumonia
Symptoms
- Return of heartburn or regurgitation
- Difficulty swallowing, either new or persistent beyond the normal healing period
- Chest pain or pressure, especially after meals
- Gas bloat: painful bloating with inability to belch
- Inability to vomit
- Nausea and early fullness, sometimes from slowed stomach emptying
- Chronic cough, hoarseness or aspiration
- Weight loss from eating less
Diagnosis
A complete workup is essential before any reoperation:
- Upper GI series (barium swallow): shows wrap position, herniation, slippage and emptying.
- Upper endoscopy: evaluates the wrap from inside, esophagitis and Barrett's; see diagnostic upper endoscopy.
- High-resolution manometry: assesses esophageal strength and wrap pressure, and uncovers motility disorders that may have been missed.
- pH or pH-impedance testing off acid medication: objectively confirms whether reflux has truly returned. Many patients with "recurrent heartburn" have normal studies.
- Gastric emptying study: identifies delayed emptying from vagal nerve injury.
- CT scan for large hernias or complex anatomy.
- Review of prior operative reports to understand what was done.
Differential Diagnosis
- Normal postoperative swallowing difficulty in the first weeks
- Functional heartburn or reflux hypersensitivity without true reflux
- Achalasia or other motility disorders
- Gastroparesis
- Peptic ulcer disease
- Cardiac chest pain
Lifestyle Modifications
- Eat smaller meals slowly and chew thoroughly.
- Avoid carbonated drinks if you have gas bloat.
- Stay upright after eating and elevate the head of the bed.
- Lose excess weight to reduce pressure on the hiatus.
- Avoid heavy lifting and straining.
- Do not restart long-term acid medication without testing to confirm reflux has returned.
Treatment Options
- Observation and targeted medication: for mild symptoms without a mechanical problem, or when testing shows no true reflux.
- Endoscopic dilation: for a wrap that is mildly tight; see esophageal dilation.
- Redo fundoplication: laparoscopic or robotic takedown of the failed wrap, complete reduction of any hernia, mobilization of the esophagus, secure hiatal closure and construction of a new wrap — often converting to a partial (Toupet) wrap when swallowing was a problem. A Collis gastroplasty can lengthen a short esophagus.
- Roux-en-Y gastric bypass: an excellent option for patients with obesity, multiple failed wraps, poor esophageal motility or delayed stomach emptying, because it controls both acid and bile reflux without relying on a new wrap.
- Treatment of a missed motility disorder: for example, myotomy when achalasia was the true diagnosis.
- Esophagectomy: rarely, for a severely damaged esophagus after multiple failed operations.
Each additional reoperation has a somewhat lower success rate and higher complication risk than the one before (Furnée et al., Journal of Gastrointestinal Surgery, 2009), which is why choosing the right operation the second time matters so much.
Problems After LINX or TIF
Not every failed anti-reflux procedure is a fundoplication. After LINX magnetic sphincter augmentation, some patients develop persistent difficulty swallowing, recurrent reflux, or — rarely — erosion of the device into the esophagus, reported in about 0.3% of implants (Alicuben et al., Journal of the American College of Surgeons, 2018). The device can usually be removed laparoscopically, often with a fundoplication performed at the same operation. After transoral incisionless fundoplication (TIF), recurrent reflux is managed with the same testing and, when needed, a laparoscopic fundoplication or bypass.
When to See a Doctor
See your surgeon if reflux returns, if swallowing remains difficult more than six to eight weeks after surgery, or if you develop painful bloating, chest pain after meals or weight loss. Seek emergency care for sudden severe chest or abdominal pain with retching, inability to swallow saliva, or vomiting blood.
When to Seek Treatment
Seek evaluation by a surgeon experienced in reoperative foregut surgery when testing confirms a mechanical problem, when symptoms affect your eating or quality of life, or when you have been told that further options do not exist. A second opinion is especially valuable before a third operation.

Long-Term Outlook
After successful revision, most patients return to a normal diet, and many are able to stop acid medication. Recovery is similar to the first operation but can take a little longer. Maintaining a healthy weight, avoiding straining, and keeping follow-up appointments help protect the repair over the long term.

Prognosis
Redo anti-reflux surgery relieves symptoms in most patients when the cause of failure is clearly identified. Results are best for anatomic problems such as wrap herniation or slippage, and less predictable when symptoms are not supported by objective testing.
Why Choose Dr. de la Cruz‑Muñoz
Revisional foregut surgery is a core part of Dr. Nestor de la Cruz-Muñoz's practice. A board-certified surgeon specializing in minimally invasive foregut and bariatric surgery in Miami who directed a bariatric surgery fellowship for 10 years, he performs redo fundoplication, redo hiatal hernia repair, and conversion to Roux-en-Y gastric bypass when a new wrap is unlikely to last — giving patients every option rather than a single default operation. His evaluation starts with complete testing and a review of prior operative reports, so the second operation fixes the actual problem. Patients traveling from outside South Florida are welcome.
Revising a failed fundoplication calls for a surgeon comfortable with complex foregut anatomy. Dr. de la Cruz-Muñoz brings over 25 years of practice and over 15,000 minimally invasive procedures to that work, spanning foregut, hernia, gallbladder, abdominal and bariatric surgery.

FAQ
Signs include the return of heartburn or regurgitation, new or persistent trouble swallowing beyond the first two months, painful bloating with inability to belch, chest pain after meals, or needing acid medication again. Symptoms alone are not enough to confirm failure, because many patients with "recurrent heartburn" turn out to have normal acid levels. The evaluation usually includes an upper GI series, endoscopy, manometry and pH testing off acid medication, which together show whether the wrap has slipped, loosened, tightened or herniated.
Yes. Redo (revisional) fundoplication is performed laparoscopically or robotically in most patients. The surgeon takes down the old wrap, reduces any hernia, frees enough esophagus to sit in the abdomen without tension, closes the hiatus and builds a new wrap, often a partial (Toupet) wrap if swallowing was a problem. In pooled studies, about eight in ten patients have a successful outcome after redo surgery, although success rates fall and risks rise with each additional reoperation (Furnée et al., Journal of Gastrointestinal Surgery, 2009).
Converting a failed fundoplication to a Roux-en-Y gastric bypass becomes the preferred salvage operation when a repeat wrap is likely to fail (Weber et al., Surgical Endoscopy, 2019). The strongest indications are obesity (BMI over 30–35), poor esophageal motility, delayed gastric emptying, severe esophagitis or Barrett's esophagus, a damaged gastroesophageal junction, and two or more prior failed operations — the very factors that predict a poor outcome with another fundoplication (Munie et al., Current Gastroenterology Reports, 2019). Bypass controls reflux by diverting acid and bile away from the esophagus rather than relying on a wrap, and it avoids the swallowing problems that a reoperative fundoplication can create in scarred tissue (Weber et al., Surgical Endoscopy, 2019). The largest conversion series reported complete symptom resolution in about 87% of patients at long-term follow-up (Weber et al., Surgical Endoscopy, 2019). The trade-off is a longer operation and lifelong nutritional monitoring, so the decision is individualized (Castillo-Larios et al., Surgical Endoscopy, 2023).
The most common reason is that the wrap and part of the stomach move back up into the chest through a hiatus that has reopened. Other causes include a wrap that slips down onto the stomach, sutures that loosen, a wrap that is too tight, or a short esophagus that pulls the repair upward. Some "failures" are actually a different problem that was missed before the first operation, such as achalasia or gastroparesis (Hunter et al., Annals of Surgery, 1999). Obesity, a large original hernia, and early straining or vomiting after surgery increase the risk.
Yes. LINX can usually be removed laparoscopically if it causes persistent trouble swallowing, recurrent reflux, or, rarely, erodes into the esophagus, which was reported in about 0.3% of implants (Alicuben et al., Journal of the American College of Surgeons, 2018). In many cases a fundoplication is performed during the same operation to keep reflux controlled. A full evaluation with endoscopy and imaging comes first to confirm the problem and plan the safest approach.
Overall, recurrence after hernia repair in bypass patients is reported at about 5–6.5% (Bregion et al., Surgery for Obesity and Related Diseases, 2026). Pouch migration into the chest is different. Suture-only repairs can fail at very high rates, while repairs reinforced with mesh or the ligamentum teres (the round ligament of the liver) have been associated with much lower recurrence: about 20% versus 72% in gastric bypass patients in one study (Kermansaravi et al., Obesity Surgery, 2026). Because these data are observational, the repair technique should be tailored to your hernia size and tissue quality. Keeping your weight stable also helps protect the repair (Kermansaravi et al., Obesity Surgery, 2026).
Yes. Scar tissue, altered anatomy and the need to undo prior repairs make revisional foregut surgery technically more demanding, and the risks are somewhat higher than with a first operation. In experienced hands, however, revisions are safe and effective, and most patients have good results. Careful evaluation with endoscopy, esophagram, manometry and pH testing beforehand is essential.
Common causes include a wrap that slips or comes apart, a hiatal hernia that recurs, a wrap that is too tight, a short esophagus that pulls the repair upward, and a motility disorder such as achalasia that was not recognized before the first operation. Obesity, chronic coughing or straining, and early heavy lifting increase the risk. Identifying the exact cause is the first step in planning a successful revision.
Most patients experience significant improvement or complete resolution of reflux after a well-planned operation. Results are best when reflux is confirmed by objective testing and the cause — such as a recurrent hiatal hernia or a failed wrap — is clearly identified. For patients with obesity or multiple prior failures, gastric bypass is often the most reliable anti-reflux option.
Yes. The LINX device can be removed laparoscopically if it causes persistent difficulty swallowing, recurrent reflux or, rarely, erosion, and a fundoplication can often be done at the same operation. Patients should know that LINX may limit future MRI scans depending on the device model and scanner strength. Your surgeon will discuss whether LINX or a fundoplication is better for you.
