Bariatric, or Weight Loss Surgery, not only helps with losing weight but also in treating of medical conditions caused by obesity, or excess weight. Surgery for weight loss and the treatment of obesity has been around since before the 1950's, however current technology and the advent of laparoscopic surgery has made bariatric surgery safer than ever for the treatment of obesity and weight related medical problems.
Sleeve Gastrectomy / Gastric Sleeve
This procedure involves removal of approximately 80 – 85% of your stomach's volume; the remaining stomach is secured closed with staples and suture. This creates a long vertical tube or banana-shaped stomach. The sleeve gastrectomy does not involve cutting or changing the sphincter muscles that allow food to enter or leave the stomach. When you eat after having this surgery, the smaller stomach will fill up quickly. You will feel full after eating just a very small amount of food. It is important that you follow the diet instructions provided by your surgeon.
There are two parts to this procedure. The creation of a small stomach pouch and then the creation of the Roux-en-Y intestinal bypass. The procedure is done mainly laparoscopically, and rarely through an open incision. After the surgery, food passes from the stomach pouch into the jejunum, bypassing the duodenum. This reduces some absorption of calories and nutrients, though currently research has shown that bariatric surgery works mainly from altering the balance of gut hormones, which decreases the sensation of hunger as well as the set weight that the body tries to maintain.
This procedure also has two parts and is sometimes done in stages. One of the benefits of Duodenal Switch is the preserving of the pyloric value. This procedure is done both Laparoscopic and Open. The stomach or restrictive portion of this procedure is the Sleeve Gastrectomy. The small bowel is divided into two parallel limbs, one limb is attached to the stomach and the other is attached to at the Duodenum (small intestine) this will keep the biliopancreatic juices away from the food you eat, until the last portion of the small intestine were the limbs are reconnected. This is commonly referred to as the common channel.
