Anti-reflux surgery is a treatment for acid reflux, also known as GERD (gastroesophageal reflux disease). GERD is a condition in which food or stomach acid comes back up from your stomach into the esophagus. The esophagus is the tube from your mouth to the stomach.
Reflux often occurs if the muscles where the esophagus meets the stomach do not close tightly enough. A hiatal hernia can make GERD symptoms worse. It occurs when the stomach bulges through this opening into your chest.
Symptoms of reflux or heartburn are burning in the stomach that you may also feel in your throat or chest, burping or gas bubbles, or trouble swallowing food or fluids.
Description
The most common procedure of this type is called fundoplication. In this surgery, your surgeon will:
- First repair the hiatal hernia, if one is present. This involves tightening the opening in your diaphragm with stitches to keep your stomach from bulging upward through the opening in the diaphragm muscle wall. Some surgeons place a piece of mesh in the repaired area to make it more secure.
- Wrap the upper part of your stomach around the end of your esophagus with stitches. The stitches increase the pressure at the end of your esophagus, which helps prevent stomach acid and food from flowing up from the stomach into the esophagus.
Surgery is done while you are under general anesthesia, so you are asleep and pain-free. Surgery most often takes 2 to 3 hours. Your surgeon may choose from different techniques.
OPEN REPAIR
- Your surgeon will make 1 large surgical cut in your belly.
- A tube may be inserted into your stomach through the abdomen to keep the stomach wall in place. This tube will be taken out in about a week.
LAPAROSCOPIC REPAIR
- Your surgeon will make 3 to 5 small cuts in your belly. A thin tube with a tiny camera on the end is inserted through one of these cuts.
- Surgical tools are inserted through the other cuts. The laparoscope is connected to a video monitor in the operating room.
- Your surgeon does the repair while viewing the inside of your belly on the monitor.
- Your surgeon may need to switch to an open procedure in case of problems.
ENDOLUMINAL FUNDOPLICATION
- This is a new procedure that can be done without making cuts. A special camera on a flexible tool (endoscope) is passed down through your mouth and into your esophagus.
- Using this tool, the surgeon will put small clips or sutures in place at the point where the esophagus meets the stomach. These clips help prevent food or stomach acid from backing up.
Why the Procedure is Performed
Before surgery is considered, your health care provider will have you try:
- Medicines such as H2 blockers or PPIs (proton pump inhibitors)
- Lifestyle changes
Surgery to treat your heartburn or reflux symptoms may be recommended when:
- Your symptoms do not get much better when you use medicines.
- You do not want to keep taking these medicines.
- You have more severe problems in your esophagus, such as scarring or narrowing, ulcers, or bleeding.
- You have reflux disease that is causing aspiration pneumonia, a chronic cough, or hoarseness.
Anti-reflux surgery is also used to treat a problem where part of your stomach is getting stuck in your chest or is twisted. This is called a para-esophageal hernia.
Risks
Risks of any anesthesia and surgery in general are:
- Reactions to medicines
- Breathing problems
- Bleeding, blood clots, or infections
Risks of this surgery are:
- Damage to the stomach, esophagus, liver, or small intestine. This is very rare.
- Gas bloat. This is when the stomach overfills with air or food and you are unable to relieve the pressure by burping or vomiting. These symptoms slowly get better for most people.
- Pain and difficulty when you swallow. This is called dysphagia. In most people, this goes away during the first 3 months after surgery.
- Return of the hiatal hernia or reflux.
- Damage to the vagus nerves that are near the esophagus and stomach, which could affect stomach function.
Before the Procedure
You may need the following tests:
- Blood tests (complete blood count, electrolytes, or liver tests).
- Esophageal manometry (to measure pressures in the esophagus) or pH monitoring (to see how much stomach acid is coming back into your esophagus).
- Upper endoscopy. Almost all people who have anti-reflux surgery have already had this test. If you have not had this test, you will need to have it.
- X-rays of the esophagus.
Tell your surgeon or nurse if:
- You are or could be pregnant.
- You are taking any medicines, including drugs, supplements or herbs you bought without a prescription.
During the week before your surgery:
- You may be asked to temporarily stop taking medicines that keep your blood from clotting. These medicines are called blood thinners. This includes over-the-counter medicines and supplements such as aspirin, ibuprofen (Advil, Motrin), naproxen (Aleve, Naprosyn), and vitamin E. Many prescription medicines are also blood thinners.
- Ask your surgeon which medicines you should still take on the day of the surgery.
On the day of your surgery:
- Follow your surgeon's instructions about when to stop eating and drinking.
- Take the medicines your surgeon told you to take with a small sip of water.
- Follow instructions for showering before surgery.
- Arrive at the hospital on time.
After the Procedure
Most people who have laparoscopic surgery can leave the hospital within 1 to 3 days after the procedure. You may need a hospital stay of 2 to 6 days if you have open surgery. Most people can return to normal activities in 4 to 6 weeks. You will start eating with liquids, then soft foods. It may take a few weeks until solid foods are tolerated well.
Outlook (Prognosis)
Heartburn and other symptoms should improve after surgery. Some people still need to take medicines for heartburn after surgery.
You may need another surgery in the future if you develop new reflux symptoms or swallowing problems. This may happen if your stomach was wrapped around your esophagus too tightly, the wrap loosens, or a new hiatal hernia develops.
