Sleeve gastrectomy, also known as a longitudinal gastrectomy, is a surgical procedure classified under bariatric surgery aimed at weight loss. This operation involves the removal of a significant portion of the stomach, specifically more than 85 percent, which results in the creation of a narrow vertical sleeve. The procedure is performed laparoscopically, meaning it is done through small incisions in the abdomen rather than through a large open incision. This minimally invasive approach typically leads to reduced recovery times and less postoperative pain for patients. During the surgery, a small incision is made to establish pneumoperitoneum, which is the introduction of gas into the abdominal cavity to create space for the surgical instruments. Additional incisions are made in the upper abdomen for the placement of trocars, which are specialized instruments that allow access to the abdominal cavity. A laparoscope, a camera that provides visualization of the surgical area, is introduced through a port created above the umbilicus. The liver is retracted to provide better access to the stomach, and the greater curvature of the stomach is mobilized by dividing the gastric vessels along this curvature. The procedure involves the use of a bougie, which is inserted endoscopically to size the remaining stomach, ensuring that the portion left intact is appropriate for effective weight loss. A gastric stapler is then employed to vertically divide the stomach, and the staple line is meticulously checked for any bleeding, which is managed using electrocautery. Finally, the excised portion of the stomach is removed through one of the ports, and the surgical instruments, including the laparoscope, are withdrawn. The incisions made during the procedure are then closed with sutures, completing the operation.
