ESG - The Non-Surgical Revolution in Weight Loss
Many individuals struggling with excess weight rightfully fear traditional bariatric surgery, which requires the irreversible resection of most of the stomach and a permanent alteration of internal anatomy. The breakthrough in the bariatric world is ESG (Endoscopic Sleeve Gastroplasty), performed using Apollo Overstitch technology.
This revolutionary procedure delivers "gastric sleeve" results-without the scalpel.
Dr. Vosko inserts the advanced suturing device through the mouth and sutures the stomach walls from the inside.
The result: stomach volume is reduced by approximately 70%-80%, leading to rapid satiety and significant weight loss.
The critical difference: The stomach remains intact in the body, the digestive system is not cut, and recovery is several times faster than surgery.
As an official Proctor who trains doctors in Israel and worldwide on this procedure, Dr. Vosko ensures you are in the most experienced hands in Israel.

Who is a candidate for this treatment?
ESG fills the vast gap between diets/injections and major bariatric surgery.
Ideal candidates include:
- BMI 30-40: Individuals with moderate to severe obesity who have been unable to lose weight through conservative methods.
- Fear of Surgery: Patients who wish to avoid the risks and scars associated with traditional surgery, or who are concerned about organ resection.
- Surgical Contraindications: Patients who cannot undergo traditional surgery due to abdominal adhesions from past procedures or high anesthetic risk.
- Medication Failure: Those who have tried weight-loss injections (such as Ozempic/Wegovy) and experienced severe side effects or weight regain upon discontinuation.
We are with you - on the journey to your new weight
The procedure is just the beginning. Our comprehensive package includes:
- Clinical Dietitian Support: Personalized follow-up sessions to help you adapt to eating with a "smaller stomach" and establish new nutritional habits to maximize your results.
- Availability: Direct WhatsApp support for any questions regarding nutrition or physical sensations during the initial days following the procedure.
This is the most important comparison for the patient. The advantage of the OverStitch procedure lies in its safety profile and the preservation of the body's anatomy.
The ESG procedure requires a much higher level of technical skill than traditional surgery, as the physician performs the suturing "remotely" through the mouth.
- Professional Authority (Proctor): Dr. Vosko is one of the few physicians selected by Apollo (the device manufacturer) to train other doctors. His experience includes hundreds of complex suturing procedures.
- Advanced Suturing Techniques: Dr. Vosko utilizes the latest suturing methods (such as "Z-pattern" or "U-stitches"), which ensure the stomach remains constricted over time and prevent it from reopening-a primary challenge encountered by less experienced practitioners.
- Multidisciplinary Support: We provide close guidance from a clinical dietitian, recognizing that while the procedure is a powerful tool, lasting change requires professional nutritional support.
A new beginning, a healthier body, without the scars.
Dr. Vosko invites you to a personal consultation regarding the ESG procedure using OverStitch technology
How is the treatment carried out?
How is the consultation conducted?
- Anesthesia: The procedure is performed under full general anesthesia.
- Approach: An endoscope, equipped with the OverStitch device, is inserted into the stomach through the mouth.
- Suturing: Dr. Vosko begins at the lower part of the stomach and works upward. He grasps the stomach wall, passes a strong and durable thread through it, and performs
a series of contractions (Plications).
- Result: The stomach is transformed from a wide "pouch" into a narrow tube (banana-shaped). Its capacity is reduced, and gastric emptying is slowed - leading to a prolonged feeling of satiety even after a small meal.
How should I prepare for treatment?
How should I prepare for the consultation?
- Tests: Preliminary gastroscopy, blood tests, and an ECG.
- Nutrition: 24 hours prior to the procedure, switch to a clear liquid diet.
- Fasting: Full fasting (including water) for 12 hours before the procedure.
- Medications: Discontinuation of blood thinners, subject to medical consultation.
What to expect the day after? (Recovery and recuperation)
Physical recovery is easy, but nutritional discipline is critical to protecting the sutures:
- Hospitalization: One night of observation with discharge the following morning.
- Pain: Abdominal cramps or nausea may occur during the first day or two (managed with medication).
- Gradual Diet:
- Weeks 1-2: Liquids only (Mandatory!).
- Weeks 3-4: Pureed or soft foods.
- After one month: Gradual return to regular food.
Are there risks or side effects?
ESG is considered significantly safer than traditional surgery:
- Nausea and Vomiting: Common during the first few days, subsiding with treatment.
- Bleeding/Infection: Very rare (less than 1%).
- Leakage: Unlike surgery (where tissue is cut), this procedure involves no cutting; therefore, the risk of a life-threatening leak is negligible.
Information for patients from abroad (medical tourism)
The unit is fully equipped to receive international patients and maintains collaborations with medical agents to provide a comprehensive logistical package.
Direct inquiries are also welcome for fast and efficient coordination.
ESG is an ideal procedure for medical tourism: it does not require long-term surgical follow-up (such as the removal of abdominal sutures), and the patient can fly back home within just a few days following the procedure, supported by remote nutritional guidance.
What is the price difference between this procedure and surgery? Is there any coverage?
ESG is a private and innovative procedure that is not yet included in the public health basket, and therefore usually involves private payment or partial coverage by certain private insurance plans (depending on policy). Our team will check your eligibility with the insurance for you.
Is it permitted to drink alcohol or carbonated beverages after the surgery?
Carbonated beverages may expand the stomach and cause discomfort, therefore it is recommended to avoid them. Alcohol is absorbed more rapidly in a smaller stomach and has a high caloric value, so it should be consumed in great moderation and with extreme caution.
Is it permitted to become pregnant after ESG?
Yes, but it is recommended to wait approximately 12 to 18 months after the procedure to allow the body to stabilize at its new weight and ensure proper nutrition for both the fetus and yourself. The procedure does not affect fertility.
Will I have loose skin (excess skin) after losing weight?
With ESG, weight loss is more moderate and healthier (approximately 15-20%) compared to radical surgeries. This allows the body to adjust better and significantly reduces the likelihood of excess skin.
Can the stomach expand again over time?
The stomach is a flexible organ. If you return to eating large amounts of food regularly, the stomach may stretch somewhat, but the sutures limit significant expansion. Maintaining the outcome depends on combining the procedure with changes in eating habits (with the guidance of our dietitian).
Volume reduction without a scalpel
In conventional surgery, the surgeon cuts and removes part of the stomach. In ESG, we use the plication technique. Imagine an "accordion" or folds in fabric: we suture the inner stomach walls to each other, folding them inward.
The result: the stomach changes from a wide sac into a shorter, narrower tube. This folding not only limits the space for food, but also slows the stomach's motility, so that food remains inside longer and you feel full for many hours—without removing any vital organ.
The fundus is the upper part ("dome") of the stomach. In a surgical sleeve gastrectomy, it is typically completely removed. In the endoscopic technique (ESG), we avoid touching the fundus and leave it intact.
Why? The wall of the fundus is very thin and rich in blood vessels, and suturing it may be dangerous. Instead, we focus on narrowing the body of the stomach beneath it.
This allows us to achieve effective weight loss while maintaining maximal safety and preventing complications such as bleeding or impaired blood supply to the stomach.
Overstitch device - "Surgical hands" without a scalpel
The Apollo Overstitch system is a technological marvel that is mounted on a standard endoscope. Prior to its development, gastroenterologists could only "cauterize" or place superficial clips that would fall off quickly.
The Overstitch enables Dr. Vosko to perform true surgical procedures through the mouth: the special needle grasps the full thickness of the stomach wall (Full Thickness) - both the mucosa and the muscle - securing strong, durable sutures that last for years.
Dr. Vosko serves as a proctor (instructor) for this device, ensuring the highest levels of precision and expertise.
