Sleeve gastrectomy, also known as vertical sleeve gastrectomy, is a surgical weight loss procedure in which a large portion of the stomach is removed, leaving behind a smaller, sleeve-shaped stomach. This limits the amount of food that can be consumed and helps patients feel full faster, leading to weight loss. The procedure is typically performed laparoscopically, meaning that it is minimally invasive and involves making small incisions in the abdomen. Sleeve gastrectomy is often used as a standalone procedure for individuals with severe obesity or as the first part of a two-stage approach for those who need further weight loss surgeries. Research in the field of sleeve gastrectomy focuses on its efficacy in achieving weight loss, improving obesity-related comorbidities such as diabetes and hypertension, and its long-term effects on patient outcomes. Studies also explore the optimal surgical technique, postoperative care, and potential complications associated with the procedure.
