Bariatric Surgery
Gastric Sleeve
Sleeve gastrectomy, or longitudinal gastrectomy, is a bariatric surgery procedure that involves removing approximately 80% of the stomach to create a reduced-volume gastric tube. This restrictive technique significantly decreases the amount of food that can be ingested and alters hunger hormones, resulting in significant and lasting weight loss.

How the Procedure Is Performed
Laparoscopy
The procedure is performed laparoscopically (4-5 small incisions of 5-12 mm).
Removal of about 80% of the stomach
The surgeon removes approximately 80% of the stomach, primarily the fundus where ghrelin (the hunger hormone) is produced.
A small-volume gastric tube
The remaining stomach tissue takes the form of a tube or sleeve of approximately 100-150 ml.
Permanent, irreversible removal
The removal is permanent and irreversible.
Sealed staple line
A watertight staple line secures the incision.

Expected Results
The sleeve gastrectomy allows for a 50 to 70% loss of excess weight within 12 to 18 months. The feeling of hunger is significantly reduced thanks to the decrease in ghrelin. There is a dramatic improvement in comorbidities: remission of diabetes in 60-80% of cases, normalization of blood pressure, and resolution of sleep apnea.
