Cardiology is a branch of medicine that deals with the disorders of the heart as well as some parts of the circulatory system. The field includes medical diagnosis and treatment of congenital heart defects, coronary artery disease, heart failure, valvular heart disease and electrophysiology. Physicians who specialize in this field of medicine are called cardiologists, a specialty of internal medicine. Pediatric cardiologists are pediatricians who specialize in cardiology. Physicians who specialize in cardiac surgery are called cardiothoracic surgeons or cardiac surgeons, a specialty of general surgery.
Laparoscopy & Bariatric Surgeon
The "Roux-en-Y gastric bypass" (RYGB) is considered the "gold standard" for weight-loss surgery by the American Society for Metabolic and Bariatric Surgery and the National Institutes of Health.
RYGB works by restricting food intake and by decreasing the absorption of food. Food intake is limited by a small pouch that is similar in size to the adjustable gastric band. In addition, absorption of food in the digestive tract is reduced by excluding most of the stomach, duodenum, and upper intestine from contact with food by routing food directly from the pouch into the small intestine.
The operation, usually performed laparoscopically, involves making five to six small incisions in the abdomen through which a small scope connected to a video camera and surgical tools are inserted.
The surgeon staples the top portion of the stomach so it is separated from the bottom to create a small stomach pouch. This small pouch restricts food intake. A section of the small intestine called the jejunum is then attached to the small stomach pouch permitting food to bypass the lower stomach, the duodenum. This bypass reduces the amount of calories and nutrients the body absorbs, called malabsorption.
