At a glance
- A Nissen wrap goes all the way around (360°); a Toupet wrap goes most of the way (about 270°), around the back.
- Both are performed with minimally invasive surgery — laparoscopic or robotic — through small incisions.
- SAGES guidelines consider both complete and partial wraps reasonable; the choice is individualized.
- Temporary swallowing tightness and bloating are common early on and usually improve over weeks.
How fundoplication works
The fundus — the upper, dome-shaped part of the stomach — is gently wrapped around the lowest part of the esophagus and stitched in place. The wrap reinforces the natural valve, so it stays closed against reflux while still opening for swallowing. Any hiatal hernia is repaired first, returning the valve to its normal position below the diaphragm.
| Feature | Nissen | Toupet |
|---|---|---|
| Wrap | Complete, 360° | Partial, about 270°, behind the esophagus |
| Reflux control | Strong | Strong |
| Swallowing and gas effects | Can be more noticeable, particularly early on | Often somewhat milder |
| Often favored when | Esophageal squeezing is normal | Squeezing is weaker, or when minimizing side effects is a priority |
A third type, the Dor (a partial wrap in front of the esophagus), is most often used with a Heller myotomy for achalasia.
Choosing the type of wrap
There is no single best wrap for everyone. The 2021 SAGES guideline suggests that either a complete or partial fundoplication is reasonable for adults with GERD, based on each patient’s circumstances and values. Studies comparing Nissen and Toupet have generally found similar reflux control, with some analyses showing fewer swallowing and gas-related side effects after partial wraps.
Factors that shape the choice include how strongly the esophagus squeezes on manometry, the size of any hiatal hernia, prior operations, and which trade-offs matter most to you. Dr. Speer’s professional profile describes a particular interest in laparoscopic tailored fundoplication — matching the wrap to the individual patient.
Who may be a candidate
Fundoplication is considered for people with reflux confirmed by testing who:
- Have persistent heartburn or regurgitation despite medication
- Would prefer not to take medication long term
- Have severe esophagitis, a reflux-related narrowing, or a significant hiatal hernia
- Have reflux-related cough or other symptoms clearly linked to reflux on testing
It is generally not recommended when reflux hasn’t been confirmed, when the esophagus doesn’t squeeze adequately for the planned wrap, or when another condition better explains the symptoms. For people with significant obesity, a gastric bypass may be the better anti-reflux operation.
Side effects and risks
Most people do well, but it’s important to know the common and less common effects:
- Swallowing tightness is expected for several weeks as swelling settles. A small number of people have longer-lasting difficulty that may need dilation or, rarely, revision.
- Gas and bloating, and a reduced ability to belch or vomit, are more common after a complete wrap and often improve over time.
- More flatulence, and in some people looser stools, can occur.
- Recurrence of reflux or of the hernia can happen over the years; some people eventually resume medication.
- Surgical risks such as bleeding, infection, injury to the esophagus or stomach, and anesthesia risks are uncommon with minimally invasive technique but are discussed before any operation.
Laparoscopic or robotic?
Both are minimally invasive approaches using small incisions, cameras, and long instruments. SAGES considers either reasonable. The choice usually reflects the specific situation and the surgeon’s approach; what matters most is a carefully performed operation.
Common questions
What are the common side effects after fundoplication?
Early swallowing tightness, bloating, and difficulty belching are the most common, and usually improve over weeks to months; a small number of people have longer-lasting problems.
- Swallowing tightness (dysphagia). Swelling at the new valve makes solid foods stick at first. This usually settles over several weeks. Persistent difficulty is less common and may be treated with endoscopic dilation, or occasionally surgery.
- Gas and bloating. A tighter valve makes it harder to release swallowed air by belching, so it can collect in the stomach and intestines. Eating slowly, avoiding carbonated drinks and gum, and not using straws can help.
- Reduced ability to vomit. More common with a complete wrap.
- Early fullness. Some people feel full sooner for a while, which can lead to modest weight loss.
- Changes in bowel habits, including more gas and, for some, looser stools.
Let your surgical team know if you can’t keep liquids down, have worsening pain, or have a fever.
What is eating like after fundoplication?
Most people move gradually from liquids to soft foods to a normal diet over several weeks, eating smaller meals slowly; your surgical team will give you specific instructions.
Every team has its own plan, and that plan comes first. In general, the approach after an anti-reflux operation is:
- Start with liquids and soft, moist foods while swelling settles, then add textures over several weeks.
- Take small bites, chew thoroughly, and eat slowly. Sitting upright while eating helps.
- Be cautious with foods that tend to stick early on — bread, dry meats, rice, and raw vegetables are common culprits.
- Avoid carbonated drinks while bloating is still a problem.
Most people return to a varied, normal diet. If food regularly sticks after the first couple of months, tell your surgeon; it can usually be addressed.
