The laparoscopic gastric bypass is the most commonly performed procedure for weight loss in the United States. The gastric bypass has undergone a steady evolution since 1950’s when the intestinal bypass was created. As obesity continued to grow along with the persistence of physicians in this field, the gastric bypass was designed as a much safer procedure. The gastric bypass is a two step operation. The first step is to reduce the stomach to the size of an egg (restriction strategy), and the other step is to rearrange the gastrointestinal tract to reduce the amount of calories absorbed (malabsorption strategy). The restriction strategy decreases the volume of food eaten at one time while the malabsorption strategy decreases the amount of calories absorbed by the body. Dr. Miranda performs the gastric bypass laparoscopically by placing small openings and a camera through small abdominal incisions, therefore, reducing the incidence of complications, pain, and hospital stay.
The Laparoscopic Adjustable Gastric Banding (or Lap Band): A bariatric surgical procedure where a silicone belt is placed around the upper stomach through small incisions and the use of a small camera. This procedure is called restrictive, where the band limits the amount of food taken by the patient before he/she feels no desire to eat. The band is called adjustable since it has a balloon along its inner surface connected to a reservoir under the skin. Through this reservoir, fluid can be added to the balloon further restricting the passage of food through the band.
