Sleeve gastrectomy also called a vertical sleeve gastrectomy is a bariatric restrictive and non-reversible technique. The surgeon creates a small, tube-shaped stomach by removing the greater portion of the stomach (2/3), particularly cells secreting ghrelin, often termed the “hunger hormone", thus, the patient feels fuller which enables rapid weight loss.
A preoperative examination is required, before the intervention. The surgery takes about two hours and is done under local anesthesia.
Post-operative hospitalisation lasts between 3 to 8 days depending on the patient’s overall condition.
