Endosleeve / ESG / Apollo Endoscopic Sleeve Gastroplasty in Istanbul
Istanbul Bariatric Center is one of the most experienced Endosleeve (Endoscopic Sleeve Gastroplasty, also called ESG, Apollo ESG, ESG-Max or non-surgical gastric sleeve) clinics in Istanbul, Turkey. Dr Murat Ustun was among the first surgeons in Turkey to deliver routine ESG using the Apollo OverStitch suturing system and the clinic has now completed over 2,000 endoscopic weight-loss procedures with international patients from the UK, US, Germany, France, the Netherlands, Australia and the Middle East. The procedure reshapes the stomach into a tubular sleeve through endoscopic suturing — no incisions, no scars, no stomach removed, same-day discharge in most cases.

ESG vs ESG-Max: What's the Difference?
"ESG-Max" is the next-generation extended Endoscopic Sleeve Gastroplasty technique that places additional reinforcement sutures (typically 8–12 vs the standard 6) for greater stomach volume reduction and improved durability in higher-BMI patients. Istanbul Bariatric Center offers both standard Apollo ESG and ESG-Max at the same all-inclusive price — Dr Ustun selects the right configuration during pre-op assessment based on BMI, anatomy and weight-loss goals.

ESG, Endosleeve, Apollo ESG, ESG-Max — Are They the Same?
Yes — these terms all describe the same family of endoscopic stomach-reduction procedures. Endoscopic Sleeve Gastroplasty (ESG) is the formal medical name. Endosleeve is the patient-friendly short name. Apollo ESG or Apollo Endosleeve refers to ESG performed with the Apollo OverStitch device (the FDA-cleared and NICE-endorsed system used at our clinic). ESG-Max is the extended-suture version for higher-BMI patients. They are all delivered by the same endoscopic team at Istanbul Bariatric Center.
