According to the American Society for Bariatric Surgery and the National Institutes of Health, Roux-en-Y gastric bypass is the most frequently performed weight loss surgery in the United States and is the gold standard procedure for weight loss surgery. The average excess weight loss after the Roux-en-Y procedure is generally higher in a compliant patient than with restrictive procedures like gastric banding and sleeve gastrectomy.
In Roux-en-Y, the stomach is divided, and a small pouch, which limits calories that can be taken in on a daily basis to less than 1,000, is formed and at the same time majority of the stomach is sealed off. A portion of the small intestine is then divided and sewn to the newly created small proximal stomach pouch. This laparoscopic surgical process limits the body’s ability to absorb calories taken by patient. This procedure can be performed as a standard open surgery, or as a laparoscopic surgery. This presentation describe some of the important aspect of Laparoscopic Roux-en-Y gastric bypass surgery.
Laparoscopic Gastric bypass procedures (LGBP) are any of a group of similar operations that first divides the stomach into a small upper pouch and a much larger lower "remnant" pouch and then by laparoscopic techniques re-arranges the small intestine to connect to both. Laparoscopic Surgeons have developed several different ways to reconnect the intestine, thus leading to several different GBP names. Any Laparoscopic Gastric Bypass leads to a marked reduction in the functional volume of the stomach, accompanied by an altered physiological and physical response to food.
Laparoscopic Gastric Bypass surgery is performed using several small incisions, or ports: one to insert a laparoscopic surgical telescope connected to a laparoscopic video camera, and others to permit access of specialized operating instruments. The laparoscopic surgeon views his operation on a high definition video screen. Laparoscopy is also called minimal access surgery, reflecting the limitation on handling and feeling tissues due to loss of tactile feedback and also the limited resolution and two-dimensionality of the surgical video image. With experience, a skilled laparoscopic surgeon can perform most general surgical and gynecological procedures as expeditiously as with an open incision, with the option of using an incision should if anytime the need of conversion arise.
