Bariatric Surgery

Bariatric surgery or weight loss surgery is a type of procedure performed on people who are dangerously obese, for the purpose of losing weight. This weight loss is usually achieved by reducing the size of the stomach with an implanted medical device (gastric banding) or through removal of a portion of the stomach (sleeve gastrectomy or biliopancreatic diversion with duodenal switch) or by resecting and re-routing the small intestines to a small stomach pouch (gastric bypass surgery).

The gastric bypass method is designed to decrease your food intake, and is more likely to achieve goals of weight loss in individuals who are suffering from obesity. Gastric bypass surgery can significantly improve your quality of life by improving your physical appearance and increasing your agility, but it can also decrease the number of health problems many overweight individuals are susceptible to. Among the health complications that can occur are diabetes, sleep apnea, heart abnormalities and circulation problems.
This complex procedure is done under general anesthesia, so you will be asleep all throughout the operation. Duration of the surgery can last between one and four hours, which is followed by a three to seven day recovery at the hospital.
Laparoscopic Roux-en-Y-gastric bypass will use several small incisions, and a laparoscopic instrument is inserted, which gives the surgeon a visual guide inside the abdomen during your procedure. This operation results in less scarring, and the recovery is quicker than the traditional gastric bypass.

Gastric sleeve surgery is one of the more recent developments in weight loss surgery. The gastric sleeve surgery involves removing about 85% of the patient’s stomach in order to attain a tube-shape, or, as the name suggests, a sleeve. This weight loss surgery is done laparoscopically, that means that the surgeon will make a few small incisions instead of one large incision.
In various cases, after a person has already lost a considerable amount of weight, the gastric sleeve surgery is followed by duodenal switch surgery or gastric bypass surgery. This is called the “staged” approach, where each surgery is done separately. By breaking down the weight loss surgeries into stages, this approach is considered less risky as compared to a single surgery that has both procedures included.

Gastric banding is an operation used to produce weight loss.Laparoscopic gastric banding is the second most common weight loss surgery, after gastric bypass. Surgeon places an adjustable silicone band around the upper part of the stomach using laparoscopic tools. Squeezed by the silicone band, the stomach becomes a pouch with about an inch-wide outlet. After banding, the stomach can only hold about an ounce of food. A plastic tube runs from the silicone band to a device just under the skin. Saline can be injected or removed through the skin, flowing into or out of the silicone band. Injecting saline fills the band and makes it tighter. In this way, the band can be tightened or loosened as needed. This can reduce side effects and improve weight loss.
Although this surgery was introduced as an ideal method in the first decade but after a while it was excluded by experienced physicians due to lack of appropriate response, poor quality of patient life, the ring side effects, and also patient dependence to physician.
