Sleeve Gastrectomy

What is a Sleeve Gastrectomy?

Sleeve gastrectomy (gastric sleeve) is currently the most commonly performed weight-loss operation worldwide.
About 75–80% of the stomach is removed, leaving a narrow, tube-shaped stomach that restricts food intake and reduces hunger.

Who are suitable candidates?

Sleeve gastrectomy is typically recommended for individuals who:

  • Have a Body Mass Index (BMI) ≥35, regardless of associated health problems.
  • Have repeatedly tried diet, exercise, or other weight-loss methods without lasting success.
  • Have received comprehensive counseling from a specialized bariatric team.
  • Are usually between 18 and 65 years old (younger or older patients may be considered individually).
  • Do not have significant reflux or Barrett’s esophagus; patients with these conditions are usually better served by a bypass-type operation.

The decision is made after full preoperative assessment in collaboration with the multidisciplinary team.

ADVANTAGES

  • Effective weight loss: Typically 25–30% TWL within the first 12–18 months.
  • Appetite reduction: Removes the stomach’s fundus, which produces ghrelin—the “hunger hormone.”
  • Improvement of associated health problems: Benefits type 2 diabetes, high blood pressure, dyslipidemia, and sleep apnea.
  • Technically straightforward: When performed by experienced surgeons, offers excellent safety and reproducibility.
  • Faster recovery: Laparoscopic procedure with early mobilization and short hospital stay.
  • Long-term benefits: Sustained results with proper nutrition, activity, and follow-up.

THE PROCEDURE

  • Surgery duration: 60–80 min
  • Hospital stay: 2–3 days
  • Recovery time: ≈ 2 weeks
  • Major complication rate: ~1–2% | Mortality: 0.1–0.3%
  • Lifelong follow-up: Routine vitamin/mineral supplementation and blood tests are essential.
