This article provides a detailed comparison between Vertical Sleeve Gastrectomy (VSG) and Endoscopic Sleeve Gastroplasty (ESG). Both bariatric procedures create a “sleeve” to restrict food intake. The VSG is a surgical procedure that removes part of the stomach. In contrast, the ESG is an incisionless procedure that reshapes the stomach from the inside.
VSG surgery resets the metabolic system as a result of hormonal changes, while ESG only reduces the food intake.
Here is a breakdown of the key differences between these weight loss procedures:
1. Procedure Mechanics
- VSG (The Surgery): A bariatric surgeon makes small incisions in the abdomen (laparoscopic) and permanently removes about 80% of the stomach. This also removes the portion of the stomach that produces most of the “hunger hormone” (Ghrelin).
- ESG (The Accordion): No incisions are made. A doctor inserts an endoscopic suturing device through the mouth and sutures the stomach from the inside to fold it into a tube. The stomach remains whole but becomes much smaller and “bunched up.”
2. Weight Loss & Health Results
- VSG: Generally more powerful. Patients typically lose 65–85% of their excess weight. It is better for resolving severe obesity-related issues like Type 2 diabetes or sleep apnea.
- ESG: Slightly less potent. Patients typically lose 30–50% of their excess weight. It is often recommended for people with a lower BMI (28–35) who aren’t candidates for major surgery.
3. Recovery & Safety
- VSG: Requires 2–3 days in the hospital and a few weeks of recovery. It is a permanent, non-reversible surgery.
- ESG: Offers a much faster recovery (often “back to work” in a few days) and has no external scarring. It is technically reversible because no tissue is removed.
| Feature | VSG (Gastric Sleeve) | ESG (Endo-Sleeve) |
|---|---|---|
| Incision | 3–5 small abdominal incisions | None (through the mouth) |
| Stomach Removal | Yes (approx. 80% removed) | No (folded and sutured) |
| Hunger Hormones | Drastically reduced | Remain mostly intact |
| Typical Excess Weight Loss | 65% – 85% | 30% – 50% |
| Ideal BMI | 30+ | 28 – 39 |
| Permanence | Permanent | Potentially reversible |
Which is better?
The article suggests that VSG is the “gold standard” for durable, significant weight loss in obese patients. On the other hand, the ESG is an excellent “middle ground” for those who want to avoid surgery or have a lower BMI. Both weight loss surgeries are suitable for patients with high blood pressure, fatty liver disease, and other obesity-related comorbidities.
