The Endosleeve (ESG) — surgery without surgery.
A scientifically validated, minimally invasive endoscopic technique that reduces stomach volume with no incisions or scarring. The result of years of international clinical research.
A Boston Scientific innovation
CE-marked 2797.
Medical innovation
in the service of your health.
The Endosleeve, or Endoscopic Sleeve Gastroplasty (ESG), reduces gastric volume by 70 to 80% without a single incision. Using the OverStitch™ system introduced through the mouth via a flexible endoscope, Dr. Sitte places internal sutures that tighten the stomach into a tubular shape.
The result: an early feeling of satiety, a natural reduction in food intake, and significant, lasting weight loss — without organ removal, without a visible scar.
- → Light general anaesthesia
- → No incision, no scar
- → Stomach fully preserved
- → Reversible: sutures adjustable or removable endoscopically
- → Outpatient or one night of observation
- → Return to activities in 2 to 3 days
Documented efficacy,
validated by science.
The efficacy and safety of the Endosleeve rest on robust scientific data, including the MERIT study (The Lancet, 2022) and a large ASGE meta-analysis of more than 5,000 patients — with morbidity and a complication rate markedly lower than those of conventional bariatric surgery.
On average, patients lose around 20% of their total body weight within the first year — a result that can reach 24% when the procedure is combined with optimised medical and nutritional support.

Is it the solution that's right for you?
The Endosleeve is intended for a specific profile. Your first consultation will determine whether this technique is best suited to your situation — and, if applicable, which alternative to consider.
Endoscopic gastroplasty can be performed on people with a body mass index (BMI) between 27 and 35, the minimally invasive procedure taking 60 to 90 minutes.
Even if you have a BMI above 40 kg/m² and/or do not wish to undergo more invasive conventional bariatric surgery, we can offer you an individual solution tailored to your needs, in collaboration with our nutrition and lifestyle-coaching team.
Overweight with comorbidities
BMI between 27 and 30 combined with metabolic comorbidities (diabetes, hypertension, dyslipidaemia, sleep apnoea).
Moderate obesity
BMI between 30 and 35 — the ideal indication range for this technique, with the best documented results.
Therapeutic alternative
Patients who do not wish to undergo conventional bariatric surgery or who have an absolute contraindication to it.
High BMI: individualised solution
Even beyond 40 kg/m², a tailor-made solution can be offered, in conjunction with our nutrition and lifestyle-coaching team.
