In this procedure a silicon band lined with an inflatable balloon is placed laparoscopically around the stomach near its upper end creating a small pouch (15 to 30 cc vol.) and a narrow passage leads into the larger remainder of stomach.
When a patient eats, the feeling of satiety or fullness of stomach is experienced early and therefore food consumption is reduced, leading to significant weight loss.
This balloon is connected to a small reservoir that is placed under the skin of the abdomen through which the diameter of the band can be adjusted by injecting fluid into it as an outpatient procedure.
Sleeve Gastrectomy is a technique that offers the same results as the Gastric Bypass but with less risk.
The Gastric 'Sleeve' is a new procedure that induces weight loss by restricting food intake (a restrictive procedure).
With this procedure, the surgeon removes approximately 80 percent of the stomach laparoscopically and with the help of staplers so that the stomach takes the shape of a tube or 'sleeve', or a very slim banana which measures from 30 to 50 cc depending upon the surgeon performing the procedure.
In addition to being restrictive, this procedure has seen that the hormone that regulates the appetite, the Ghrelina, diminishes, causing the patient to have less desire to eat.
In a laparoscopic gastric bypass, the stomach is made smaller by creating a small pouch (30 ml) at the top of the stomach using surgical staples. The smaller stomach is connected directly to the middle porting of the small intestine (Jejunum), bypassing the rest of the stomach and the upper portion of the small intestine (Duodenum). The small stomach makes you feel full more quickly and part of small intestine bypass causes reduced calories and nutrient absorption, which ultimately leads to weight loss.
