Laparoscopic Gastric Sleeve Procedure
Dr. Lance Mayabi, Bariatric & Endoscopic Weight Loss Specialist, Nairobi
What is Laparoscopic Gastric Sleeve Surgery?
Laparoscopic Gastric Sleeve, also known as Sleeve Gastrectomy, is a minimally invasive weight loss procedure designed to help individuals achieve significant and sustainable weight loss. This procedure involves the surgical removal of approximately 75-80% of the stomach, leaving behind a smaller, sleeve-shaped stomach that limits food intake while promoting a feeling of fullness.
How It Works
During the procedure, the surgeon makes small incisions in the abdomen and uses laparoscopic techniques to remove a large portion of the stomach. The remaining stomach is reshaped into a tube or “sleeve,” reducing its capacity. This results in decreased food consumption and changes in hunger-regulating hormones, leading to effective long-term weight loss.

Benefits of Laparoscopic Gastric Sleeve
-
Significant and sustainable weight loss – Patients typically lose 50-70% of their excess weight within 12-18 months.
-
Minimally invasive – The laparoscopic approach ensures smaller incisions, reduced pain, and faster recovery.
-
Improved metabolic health – Helps in the management and resolution of obesity-related conditions such as type 2 diabetes, high blood pressure, and sleep apnea.
-
No foreign implants – Unlike gastric banding, this procedure does not involve the placement of a device in the body.
-
Enhanced quality of life – Patients experience improved mobility, increased energy levels, and greater self-confidence.
