The Sleeve Gastrectomy is now the most commonly performed weight-loss operation in the United States. It has outstanding results and fewer complications than any other surgical procedure. The operation is performed using the laparoscopic technique, requiring several small incisions, from 1/4 inch to an inch in length. Patients stay in the hospital over night, and the vast majority go home on the day following surgery. Weight loss is rapid and steady, often reaching your target weight within 8 to 12 months.
