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.

Procedure of the Intervention
The procedure is performed laparoscopically (4-5 small incisions of 5-12 mm). The surgeon removes approximately 80% of the stomach, primarily the fundus where ghrelin (the hunger hormone) is produced. The remaining stomach tissue takes the form of a tube or sleeve of approximately 100-150 ml. The removal is permanent and irreversible. A watertight staple line secures the incision.
Post-operative monitoring and recovery
Resumption of a liquid diet from day 1, followed by soft textures for 3-4 weeks before gradual reintroduction of solid foods. 2-4 weeks of sick leave. Lifelong vitamin supplementation is mandatory. Regular dietary monitoring is required. Rapid weight loss is expected during the first 6 months, stabilizing at 12-18 months.

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.
