Lose weight
without surgery.
It's possible.

What is the Endosleeve?

The sleeve, without the operating room.

The Endosleeve — or Endoscopic Sleeve Gastroplasty (ESG) — is a minimally invasive technique that reduces stomach volume through the mouth, with no abdominal incision. Using a flexible endoscope and Boston Scientific's OverStitch™ system, Dr. Sitte places internal sutures that tighten the stomach into a tubular shape — the effect of a sleeve, without its surgical risks.

Our commitments

Three fundamental principles
at the heart of your weight loss.

A rigorous, transparent and human medical approach — designed for patients seeking care that meets international standards.

Clinical safety

A minimally invasive method validated by the MERIT study, with reduced morbidity compared with surgery and overseen by a rigorous hospital protocol. No incision, no removal: the stomach is preserved and the procedure remains reversible — the sutures can be adjusted or removed endoscopically.

Documented efficacy

Results validated by the MERIT study (The Lancet, 2022): significant, lasting weight loss and a marked improvement in metabolic comorbidities — diabetes, hypertension, sleep apnoea, hepatic steatosis.

Comprehensive support

A structured 12-month programme alongside a multidisciplinary team — physician, dietitian/nutritionist, physical-activity coach, behavioural support.

Your journey

A structured and caring medical journey. Every step is designed to support you calmly — from the first question to lasting transformation.

Dr. Sitte's expertise

An expert centre, not just a consultation.

Dr. Sitte combines two skills that are rare in Europe: endoscopic gastroplasty (ESG) for metabolic medicine, and endoscopic submucosal dissection (ESD) — a high-precision microsurgical technique.

This dual command places his practice in a distinct category: that of advanced therapeutic interventional endoscopy, at the intersection of medical innovation and early oncological care.
