Quick Answer: What is a TIF procedure?
A TIF procedure (transoral incisionless fundoplication) is an endoscopic treatment for chronic acid reflux (GERD) and small hiatal hernias. Working through the mouth with no cuts, a provider folds the top of the stomach around the lower esophagus and fastens it, tightening the valve between them. Early results suggest it works for about 80% of people after five years. [1]
What the research says
TIF eases reflux symptoms beyond heartburn. A meta-analysis of 10 studies with 564 patients found that TIF lowered scores for throat and voice reflux symptoms by about 15 points at 6 and 12 months, with a 99.5% technical success rate and a 1% adverse event rate. About three-quarters of patients were off daily acid-reducing pills. (Haseeb et al., Gastrointestinal Endoscopy, 2023) [2]
TIF ranks among the most effective endoscopic reflux treatments. In a network meta-analysis of 19 randomized trials with 1,181 patients, TIF improved reflux quality-of-life scores and reduced esophagitis compared with proton pump inhibitors, and it was the only endoscopic therapy that significantly raised lower esophageal sphincter pressure. It was less effective than medicine at lowering acid exposure. (Yao et al., Journal of Gastrointestinal Surgery, 2024) [3]
Surgical Nissen fundoplication controls acid more strongly. A meta-analysis of 78 studies with 9,516 patients found that all anti-reflux procedures improved acid exposure and symptom scores, but compared with Nissen fundoplication, TIF produced less improvement in acid exposure time and DeMeester score. (Tadé et al., Surgical Endoscopy, 2025) [4]
Key takeaways
TIF treats chronic acid reflux and small hiatal hernias through the mouth, with no incisions. [1]
It suits people with mild to moderate GERD who want a lasting option without surgery or long-term acid-reducing pills. [1]
The procedure takes about 45 to 60 minutes; some people go home the same day. [1]
Your diet moves from clear liquids to soft foods over about two to six weeks. [1]
Early results suggest about 80% success after five years, though long-term data are limited. [1]
What is a TIF procedure?
TIF stands for transoral incisionless fundoplication. "Transoral" means through the mouth, and "fundoplication" means folding the top part of the stomach (the fundus) around the esophagus. [1]
Folding the stomach around the lower esophagus tightens the junction between them, which acts like a valve to keep stomach acid from flowing back up. TIF is an option for people with mild to moderate GERD who want a long-lasting solution without surgery or years of proton pump inhibitors (PPIs). It can also treat a minor hiatal hernia. [1]
Who is a candidate for TIF?
A gastroenterologist or general surgeon will decide whether TIF is right for you. Tests may include: [1]
Who should not have a TIF procedure?
TIF may not be a good fit if you have any of these: [1]
Condition | Why it matters |
Large hiatal hernia | TIF is designed for small hernias only |
Swallowing disorder | A tighter valve may make swallowing problems worse |
Severe erosive esophagitis | Heavy damage to the esophagus lining needs other treatment |
Barrett's esophagus | Changed esophagus lining rules out TIF |
Esophageal stricture | A narrowed esophagus is not suitable for TIF |

How do you prepare for a TIF procedure?
What happens during a TIF procedure?
You are put to sleep with general anesthesia. [1]
The provider passes an endoscope and a fundoplication device through your mouth and down your esophagus. [1]
Using the device, the provider folds the top of your stomach around the lower esophagus. [1]
The fold is secured with fasteners, staples or stitches. [1]
The procedure itself takes about 45 to 60 minutes, although the whole appointment is longer. Some people go home the same day, and others stay overnight. [1]
TIF procedure at a glance
Item | Typical detail |
Approach | Through the mouth with an endoscope; no incisions |
Anesthesia | General (you are asleep) |
Fasting | 12 hours before |
Procedure time | About 45 to 60 minutes |
Hospital stay | Same day or overnight |
Back to normal activities | Within a few days |
Vigorous exercise | Avoid for up to a month |
Sources: [1]
How painful is a TIF procedure?
Most people need only moderate pain relief for about a day. A sore throat, chest pain and shoulder pain are expected for a few days afterward. [1]
What is recovery like after a TIF procedure?
You will keep taking some medicines for a few days. Most people can return to normal activities within a few days but should avoid vigorous exercise for up to a month. [1]
Your diet moves forward in stages over about two to six weeks, giving the new fold time to heal: [1]
Your diet moves from clear liquids to soft foods over a few weeks.
What are the benefits and risks of TIF?
TIF offers a middle option between lifelong medicine and anti-reflux surgery. Early results suggest about 80% success after five years, although long-term data are limited. [1]
Complications are unlikely but can include: [1]
Possible complication | What it means |
Injury to the esophagus or stomach | Bleeding, a tear or a hole (perforation) |
Infection | Including mediastinitis, an infection in the center of the chest |
Returning symptoms | Reflux symptoms that come back over time |
Sources: [1]
How does TIF compare with Nissen fundoplication?
Both procedures wrap the top of the stomach around the esophagus, but they differ in how they are done and how tight the wrap is. [1]
TIF is a gentler, incision-free alternative to surgical fundoplication.
Feature | TIF | Nissen fundoplication |
How it is done | Endoscope through the mouth | Surgery through abdominal incisions |
Incisions | None | Yes |
Wrap | More moderate | Typically tighter |
Possible side effects of the wrap | Fewer | Trouble swallowing, burping and vomiting |
Sources: [1]
If medicines are not controlling your symptoms, TIF may be well worth considering, as long as you are a suitable candidate. Another incision-light option is the LINX procedure. [1]
When should you call your doctor after a TIF procedure?
Some throat, chest and shoulder soreness is expected for a few days. Contact your care team if pain gets worse instead of better, or if you have a fever, vomiting, trouble swallowing liquids, black or bloody stools, or shortness of breath, and follow the specific instructions you are given before you go home.
Conclusion
GERD affects up to 20% of U.S. adults. For people with mild to moderate reflux and only a small hiatal hernia, a TIF procedure can rebuild the valve between the esophagus and stomach through the mouth, with no incisions, a short procedure and a quick return to daily life. [1]
If acid reflux keeps coming back despite medicine, ask your gastroenterologist whether testing for TIF makes sense for you.
