How does the nissen fundoplication reduce the symptoms of gerd?

Reinforce LES. The lower esophageal sphincter (les) is a high pressure zone at the junction of where the esophagus meets the stomach. In reflux disease the les is weakened, allowing stomach acid to reflux back into the esophagus, causing symptoms of gerd. The nissen procedure restores the pressure of the les by wrapping a portion of the stomach around the junction.
Multiple Ways. A nissen is wraping the loose upper portion of the stomach around the lower esophagus to reinforce the valve that is located there to prevent reflux from the stomach into the esophagus. It also works by bringing the lower esophagus into the abdominal cavity where pressure is greater, furthing reinforcing the valve. Also an hiatel hernia found at the time is repaired.
Tightening wrap. Gerd (gastroesophageal reflux disease) occurs typically when the lower esophageal sphincter (les) is lax. This allows for stomach acid to splash up into the end of the esophagus creating the burning sensation. The fundoplication is a surgical procedure that wraps the top of the stomach around the base of the esophagus in order to tighten the sphincter to prevent this backwash.
Preventing reflux. Fundoplication prevents reflux of stomach contents into the esophagus and thus reduces or eliminates symptoms.

What are the most common complications of a nissen fundoplication for gerd?

EARLY or LATE? Early complications include injury to the stomach, esophagus, or adjacent organs (spleen). Late complications may be due to the wrap being too tight (difficulty swallowing, gas-bloat syndrome) or too loose (persistent reflux). Rarely, nerve injury can lead to diarrhea and/or poor emptying of the stomach. Read more...
Bloating. The most common symptom patients have after nissen is bloating but goes away in most cases. The second most common is trouble swallowing and it also resolves on most cases. As in any advanced surgery make sure is done by experienced surgeons. Read more...
There are ... Generic risks such as infection, rare as it is a clean operation. If it is a laparoscopic procedure, there is the risk of conversion to open with a larger incision. The fundoplication might be made too tight making it difficult to swallow. It might also come unwrapped resulting in recurrent reflux symptoms. It might be harder to burp or vomit afterwards. Have a good discussion with your surgeon. Read more...

How long does it normally take to recover after having a nissen fundoplication for gerd?

Days-to-weeks. Following a laparoscopic fundoplication, there is minimal incisional pain which can be managed as an outpatient within a few days after surgery. However, there is often swelling around the "wrap" that may make eating a normal diet quite difficult for weeks. Read more...

What tests should be run before considering a nissen fundoplication to manage severe, chronic gerd?

Hiatal hernia & GERD. An upper endoscopy can reveal a hiatal hernia which may be readily amendable to surgical correction via nissen fundoplication. An upper GI study, ct scan & ultrasound may or may not be needed as egd is usually capable of identifying hiatal hernia. Endoscopic hiatal hernia repair is another procedure one can consider for this problem. H. Pylori should be tested for and eradicated. Read more...
GI series. I upper gastrointestinal barium x ray series to look for areas of narrowing or twists that could be causing gerd should be done.

Several. The work up for surgery for gerd includes an exam by the surgeon, an upper endoscopy preferably by the surgeon, possibly a test to measure how much acid is coming up, and an esophageal manometry which tests the function of the esophagus. Sometimes an x-ray UGI is also done. Read more...

Is LINX System a better option for me than Nissen Fundoplication? If I have severe GERD LES (0, 3mHg)? Thanks

No . No Nissan fundoplication have a fifty years or more of success in spite being more invasive has better track record of success now done with laparoscope as out patient make it more appealing the surgery fix the problem of hernia and reflux at the same time any other alternative like LINX could prevent reflux for a short time and it does not have long record of success yet get second opinion .

How does esophyx compare to nissen fundoplication in terms of efficacy and safety? I have bad GERD and laryngitis. Which should I do?

Both have pros&cons. Bad gerd with laryngitis that is poorly managed with meds makes you a candidate for either procedure. Esophyx is endoscopic without scars but is newer, less studied& not indicated for big hiatal hernia. Laparoscopic nissen fundoplication is the gold standard but it is a surgery/more expensive and makes it difficult to heave or burp. They are both operator dependent & patient selection is key.

Both are good. . Both are good. The nissen is 90-95% successful but has a relatively high side effect profile (up to 60% in some studies) for bloating and trouble swallowing. The esophyx is 80-85% successful but only has about a 2% bloat and dysphagia rate. A hybrid tif can be done to fix the hiatal hernia laparoscopically then do the transoral wrap with the esophyx device. Talk to a surgeon who does both. Read more...

I have had GERD for 12 years been on ppis since then. I am 32, 6' 175lbs. Considering nissen fundoplication to get off ppis and help with regurgitation. Tests are good but I am hesitant, any advice?

Well... I am not a GI specialist but do see a lot of patients with gerd. If the ppi has controlled your symptoms, then surgery is probably not needed. Since your are not obese by any means, weight loss would not help you much. The fundoplication is an endoscopic procedure and you will likely benefit from it for a decade or more and i would certainly consider it if ppi has been partly beneficial. Read more...
