What is Reflux (GERD)?

GERD (gastroesophageal reflux disease) happens when stomach acid (and sometimes bile) flows backward into the esophagus. This can cause:

• Heartburn / burning chest discomfort
• Regurgitation (sour or bitter fluid coming up)
• Chronic cough, hoarseness, throat clearing, asthma-like symptoms
• Trouble swallowing, chest pain, or a feeling of food “sticking”
• Sleep disruption from nighttime reflux

Reflux often worsens when the lower esophageal sphincter (LES) is weak or when there is a hiatal hernia (part of the stomach slips up through the diaphragm).

When Should Reflux Surgery Be Considered?

Many patients improve with lifestyle changes and medications (like PPIs). Surgery is considered when:

• Symptoms persist despite optimal medication and lifestyle changes
• You need long-term daily medications and want a durable alternative
• You have reflux complications (esophagitis, stricture, Barrett’s case by case)
• You have a hiatal hernia contributing to symptoms
• You experience regurgitation that medications don’t fully control
• You have medication side effects or cannot tolerate them

Important: Surgery works best when your symptoms truly come from reflux so confirming the diagnosis is key.

What is Robotic Reflux Surgery?

Robotic reflux surgery is a minimally invasive procedure performed through small incisions using a robotic surgical system controlled by the surgeon. The goal is to:

1. Repair the hiatal hernia (if present), and
2. Rebuild a strong anti-reflux valve at the bottom of the esophagus.

The robotic platform helps with precise dissection and suturing, which can be especially helpful for hiatal hernia repairs and complex anatomy.

What Operation Do You Perform for Reflux?

Most anti-reflux operations involve one of these approaches (your final plan depends on your testing and anatomy):

1) Fundoplication (wrap)

The top of the stomach is wrapped around the lower esophagus to strengthen the valve.

• Nissen fundoplication (360° wrap): strongest reflux control for many patients
• Toupet fundoplication (270° partial wrap): often used when swallowing function is weaker to reduce postoperative swallowing difficulty

2) Hiatal Hernia Repair (often done together)

If a hiatal hernia is present, the stomach is reduced back into the abdomen and the diaphragm opening is tightened (cruroplasty). In selected cases, reinforcement may be considered.

Testing Before Surgery

Before robotic reflux surgery, patients often need some combination of:

• Upper endoscopy (EGD) to check esophagus and stomach lining
• Barium swallow to assess anatomy and hernia size
• Esophageal manometry to measure swallowing/pressure function
• pH testing (often pH/impedance) to confirm abnormal reflux

These tests help confirm GERD, guide which wrap is best, and reduce the risk of persistent symptoms after surgery.

Benefits of Robotic Reflux Surgery

In the right patient, surgery can provide:

• Significant improvement in heartburn and regurgitation
• Reduced dependence on reflux medications
• Repair of hiatal hernia and related symptoms (chest pressure, regurgitation)
• Minimally invasive recovery: small incisions, less pain, faster return to activity compared with open surgery

Recovery: What to Expect

Day of surgery / hospital stay

• Many patients go home same day or next day depending on the repair and medical history.

Diet

• You’ll follow a staged diet (often liquids → soft foods → regular foods over several weeks).
• Eating slowly, small bites, and avoiding carbonated drinks early on helps.

Activity

• Walking right away is encouraged.
• Heavy lifting is usually limited for a few weeks (your surgeon’s instructions vary based on hernia size/repair).

Return to work

• Desk work: often 1–2 weeks
• More physical work: commonly 2–4+ weeks, depending on lifting demands and hernia complexity

Risks and Side Effects

Robotic anti-reflux surgery is very safe, but possible risks include:

More common / usually temporary

• Difficulty swallowing (dysphagia) early on (often improves as swelling resolves)
• Gas-bloat symptoms (more difficulty burping; increased bloating)
• Mild nausea, shoulder discomfort, incision soreness

Less common

• Wrap too tight or too loose (may require dilation or revision)
• Recurrent hiatal hernia or recurrent reflux over time
• Bleeding, infection, pneumonia, blood clots

Rare but serious

• Injury to esophagus, stomach, spleen, or nearby structures
• Need to convert to open surgery for safety (uncommon)

Who Is a Great Candidate?

Surgery tends to work best for patients with:

• Objective evidence of reflux (pH testing and/or esophagitis)
• Symptoms that correlate with reflux events
• Hiatal hernia contributing to GERD
• Realistic expectations about diet progression and recovery

Questions to Ask at Your Consultation

• Do my tests confirm GERD, a hiatal hernia, or both?
• Which operation do you recommend (Nissen vs Toupet) and why?
• What diet stages will I follow after surgery—and for how long?
• When can I return to work, gym, and lifting?
• What is the chance I’ll still need reflux medication afterward?
• What symptoms after surgery are normal vs urgent?
