Stretta - General Information
Not every patient with reflux needs surgery or suturing. Sometimes, all the sphincter muscle needs is "strengthening".
The Stretta treatment is a non-invasive endoscopic procedure that uses Radiofrequency (RF) energy to thicken and strengthen the Lower Esophageal Sphincter (LES). No incisions, no stitches, and no implantation of foreign bodies.
Dr. Vosko offers Stretta as the ideal intermediate solution for patients with mild to moderate reflux who want to stop relying on medications.
Looking for a gentle and non-surgical solution?
Check your suitability for Stretta.
Who is this treatment for?
- Mild-Moderate GERD: Patients dependent on medications but without a large hiatal hernia.
- Post-Bariatric Surgery: Patients who underwent gastric sleeve and suffer from reflux (a group difficult to treat surgically).
- Surgical Failure: Patients who underwent reflux surgery in the past and symptoms returned.
- LPR: Throat reflux symptoms.
The big advantage: Zero anatomical change. No "burning bridges."
- Personalization: Dr. Vosko performs the full range of treatments (Stretta, TIF, GERDx). If he recommends Stretta, it is because it truly suits you, not because it's "the only hammer in the toolbox".
- Precision: Strict adherence to electrode positioning accuracy to achieve maximal effect without nerve damage, while maintaining a full treatment protocol (large number of burns) to ensure maximal results.
The gentle solution for heartburn.
Dr. Vosko invites you for Stretta treatment without surgery.
How is the treatment carried out?
How is the consultation conducted?
The procedure is performed under sedation. A catheter with a balloon and tiny electrodes is inserted into the esophagus. The doctor inflates the balloon and inserts the small needles into the muscle.
Controlled RF (Radiofrequency) energy is delivered. The heat causes micro-injury to the muscle, and the body responds by producing collagen and remodeling the tissue.
The result: The muscle thickens and strengthens.
How should I prepare for treatment?
How should I prepare for the consultation?
Fasting: 6-8 hours prior.
What to expect the day after? (Recovery and recuperation)
- Recovery: Most patients are discharged home about an hour after the procedure and return to work the next day.
- Diet: Soft/liquid diet for two weeks to prevent irritation in the area.
When is improvement felt?
It is important to know: The result is not immediate. The collagen building process (Muscle Remodeling) takes time.
Improvement in heartburn is usually felt starting from the second or third month and peaks after about six months. Medications should continue to be taken during the initial period.
Are there risks or side effects?
This is one of the safest procedures. Rare risks: temporary difficulty swallowing, mild fever, or superficial injury to the mucosa.
Information for patients from abroad (medical tourism)
The unit is equipped to receive international patients and collaborates with agents for a full logistical envelope.
Direct inquiries are also welcomed for rapid and efficient coordination.
An ideal procedure for tourists: short, no hospitalization, no stitches to remove, and allows rapid return to flight.
For your convenience, Dr. Vosko is fluent in Hebrew, English, and Russian.
Do I need a special diet afterwards?
Only for the first two weeks (soft and lukewarm foods) to allow the area to heal from the irritation. Afterwards, there are no special dietary restrictions, and most patients find they can return to eating foods that previously caused them heartburn.
Does the treatment leave scars in the esophagus?
There are no visible external scars, nor scars that cause narrowing. The heating causes remodeling at the fiber level within the muscle without damaging the delicate lining that covers the esophagus.
Is it possible to stop taking medication permanently?
Approximately 75% of patients are able to completely discontinue their medication (PPI). Some patients will need to continue with a low dose or take medication only "as needed" on special occasions, but their quality of life improves remarkably.
Am I allowed to undergo MRI in the future?
Yes. The treatment uses energy only and does not leave any implant or metal in the body. There are no restrictions on future imaging tests.
When will I start to feel relief from heartburn?
Unlike surgery, where the effect is immediate, improvement with Stretta is gradual. It takes about 3 to 6 months for the muscle and collagen tissue to regenerate and strengthen. Patience is required, as the full results are typically felt only after about six months.
Acid reducers from the family of proton pump inhibitors
PPIs are potent and effective acid reducers that act by inhibiting the proton pump in the stomach cells - the main mechanism responsible for the production of stomach acid.
As a result, there is a significant and sustained reduction in acid secretion, which enables symptom relief and healing of the upper gastrointestinal mucosa.
Medications from this class are used, among other indications, to treat the following conditions:
- Heartburn and gastroesophageal reflux (GERD)
- Esophagitis (inflammation of the esophagus)
- Stomach and duodenal ulcers
- As part of the treatment for Helicobacter pylori infection (H. pylori)
- Conditions of excessive acid secretion
Common medications from this group include:
- Omeprazole (Omeprazole)
- Esomeprazole - Nexium (Esomeprazole / Nexium)
- Pantoprazole (Pantoprazole)
- Lansoprazole (Lansoprazole)
In most cases, it is recommended to take PPI medications before meals, according to your doctor's instructions, and only for the required duration.
Reflux is a condition in which the contents of the stomach flow back from the stomach into the esophagus.
This disease, called gastroesophageal reflux disease (GERD), is a condition where chronic acid reflux becomes an ongoing problem.
As a result, the tissues of the esophagus are damaged, leading to chronic inflammation.
Gastroesophageal reflux disease (GERD) is a very common condition among the general population. Symptoms such as heartburn or regurgitation (the rise of stomach contents into the esophagus and throat) are reported in 25% of patients in developed countries each year. Although medication treatment provides a solution for a significant portion of patients, a considerable number of individuals (ranging from 10% to 40% of patients) may not achieve complete resolution of symptoms.
Given the significant impact of symptomatic GERD (Reflux) on quality of life, along with the high costs and growing awareness of potential negative effects associated with long-term medication use.
Now, after years of anticipation, we are proud to stand at the forefront of medical technological innovation and bring patients in Israel the groundbreaking Transoral Incisionless Fundoplication (TIF) procedure.
TIF is a minimally invasive, endoscopic procedure, much safer compared to surgery, offers faster recovery for patients, and delivers impressive clinical outcomes.
Multiple international studies have shown that the TIF procedure is successful in up to 99% of patients, with only 2% experiencing issues during or after the procedure, such as a tear or internal bleeding. For many patients, TIF provides significant relief from reflux symptoms and improves quality of life. Most patients (91%) also experience a reduction in hiatal hernia, and many (89%) are able to discontinue medication. Symptom relief after TIF typically lasts between eight to ten years, which is comparable to the outcomes in most surgical treatments. When reflux symptoms return.
When comparing with Israel, this means that about 250,000 to 500,000 people are potential candidates for endoscopic TIF treatment for reflux, which can significantly improve their quality of life and help them discontinue chronic medication.

Stretta treatment is an innovative and minimally invasive solution for gastroesophageal reflux disease (GERD). This unique method uses radiofrequency (RF) energy to strengthen the lower esophageal sphincter (LES), thereby significantly reducing reflux symptoms and improving patients' quality of life.
A burning sensation accompanied by burning pain in the chest area, behind the breastbone, and in the throat. At times, the burning sensation may extend to the neck and reach the mouth.
The symptoms usually appear after eating, but may also occur at night. Lying down or bending forward may worsen the symptoms.
Excess weight, pregnancy, a high-fat diet, nighttime eating, and smoking increase the risk of developing Heartburn.
In most cases, lifestyle changes will alleviate the unpleasant sensation.
Acid reflux from the stomach into the esophagus. Causes heartburn, pain when swallowing, and chronic cough.
Gastroesophageal reflux disease (GERD (Reflux), in English: GERD, Esophageal Reflux) is a disorder in which acidic content, which normally remains in the stomach, flows from the stomach up into the esophagus and causes a burn in the inner lining of the esophagus (the tube that connects the mouth to the stomach). Sometimes gastric juices can even reach the throat and the oral cavity.
GERD (Reflux) means to flow back or to return. Gastroesophageal reflux is a condition in which what is in the stomach returns to the esophagus.
During normal digestion, the lower esophageal sphincter opens to allow food into the stomach. Afterward, it closes to prevent food and acidic gastric juices from flowing back into the esophagus. GERD (Reflux) occurs when the lower esophageal sphincter is weak or relaxes when it should not.
The upward movement of acidic content into the esophagus causes various symptoms that impair the patient's quality of life, including heartburn. Furthermore, the burn caused by the acidic content can result in long-term damage.
Gastroesophageal reflux disease is caused by a malfunction of the muscular ring between the esophagus and the stomach. This ring is called the lower esophageal sphincter.
GERD symptoms can be alleviated through dietary and lifestyle changes. However, some individuals may require medication or surgery.
Risk factors for GERD (Reflux)
More than 25% of the population in Israel suffer from heartburn at least once a month, and over 5% of adults experience heartburn daily, including many pregnant women. Recent studies show that GERD is more common in infants and children than doctors previously thought. This can cause repeated episodes of vomiting. It can also lead to coughing and other breathing problems.
Some physicians believe that hiatal hernia may weaken the lower esophageal sphincter and increase the risk of gastroesophageal reflux. A hiatal hernia occurs when the upper part of the stomach moves into the chest through a small opening in the diaphragm (the diaphragmatic hiatus). The diaphragm is the muscle that separates the abdomen from the chest.
Recent studies indicate that the opening in the diaphragm assists in supporting the lower end of the esophagus.
It is important to note that many people with a hiatal hernia do not experience heartburn or GERD (Reflux). However, a hiatal hernia may allow stomach contents to leak more easily into the esophagus.
Coughing, vomiting, straining, or sudden physical exertion may increase abdominal pressure and lead to a hiatal hernia. Many healthy people aged 50 and over have a small hiatal hernia. Although it is usually a condition of middle age, hiatal hernias can affect people of all ages.
Hiatal hernias usually do not require treatment. However, treatment may be necessary if the hernia is at risk of strangulation, or is twisted in a way that cuts off the blood supply. Treatment for the hernia may be needed if you also have severe GERD (Reflux) or inflammation.
Several other factors can increase the likelihood of developing GERD (Reflux):
Overweight or obesity, pregnancy, delayed gastric emptying, connective tissue diseases such as rheumatoid arthritis, scleroderma, or lupus, dietary and lifestyle choices can worsen acid reflux if you already have it: smoking, certain foods and drinks, including chocolate and fatty or fried foods, coffee, and alcohol, large meals, eating before bedtime, certain medications including aspirin.
The most common symptom of GERD (Reflux) is heartburn. This usually feels like a burning pain in the chest that starts behind your breastbone and moves upward toward your neck and throat. Many people say it feels as though food is coming back up into the mouth, leaving a sour or bitter taste.
The burning, pressure, or pain of heartburn can last up to two hours. It is often worse after eating. Lying down or bending over can also trigger heartburn. Many people feel better if they stand upright or take an antacid that neutralizes acid in the esophagus.
People sometimes mistake heartburn pain for the pain of heart disease or a heart attack, but there are differences.
Physical activity can worsen the pain in heart disease, and rest may relieve it.
Heartburn pain is less likely to be brought on by physical activity. However, you cannot always tell the difference, so seek immediate medical assistance if you experience chest pain. In addition to pain, you may also experience nausea, bad breath, breathing difficulties, difficulty swallowing, vomiting, erosion of tooth enamel, and the sensation of a lump in the throat. If you have acid reflux at night, you may also have: persistent cough, laryngitis, sudden onset or worsening of asthma, or sleep problems.
In addition to heartburn, you may also experience:
Nausea
Bad breath
Breathing difficulties
Difficulty swallowing
Vomiting
Erosion of tooth enamel
Sensation of a lump in the throat
Persistent cough
Laryngitis
Sudden onset or worsening of asthma
Sleep problems
