Types of Bariatric Surgery:

Laparoscopic Adjustable Gastric Banding

Gastric banding, usually done laparoscopically, is a less invasive and the only adjustable and reversible obesity surgery available. During this procedure, surgeons place an inflatable silicone band around the upper stomach to create a new, tiny pouch that limits the amount of food that can be consumed and slows its progression into the stomach and intestines. The patient feels full sooner and satisfied with smaller amounts of food, ultimately losing up to 40 to 60 percent of his http://www.ossanz.com.au/images/laparoscopic_adjustable_band.jpgor her excess weight over three years. Normal activities can be resumed in one to two weeks. The band itself is adjustable by adding or removing fluid from the band’s interior through a small port that is placed beneath the patient’s skin. Adjustments can be made as necessary in the surgeon’s office, where the surgeon can adjust the band via the port with minimal discomfort to the patient. If the band ever needs to be removed, the stomach will return to its original form and function.





 

Laparoscopic Sleeve gastrectomy

Sleeve gastrectomy is a procedure in which the stomach is reduced to about 25% of its original size to limit the volume of food intake at one time, by surgical removal of a large portion of the stomach along the greater curvature. This is done by using surgical staplers to form a sleeve or a tube with a banana shape.Patients who have sleeve gastrectomy operations generally lose 70 percent of their excess weight within one-and-a-half years.



 



Laparoscopic Gastric Bypass (Roux-en-Y Gastric Bypass)

http://dredwardoliveros.com/droliveros/wp-content/uploads/2013/12/Laparoscopic-Gastric-Bypass-ReY.jpgGastric bypass procedures reduce absorption of food, in addition to restricting food intake. Patients who have bypass operations generally lose 70 percent of their excess weight within one-and-a-half years. In Roux-en-Y gastric bypass (LRYGB), the most common gastric bypass procedure, a small (30 ml) stomach pouch is created by stapling to separate it from the rest of the stomach. Then, a section of the small intestine is attached to the new pouch to allow food to bypass the first portion of the small intestine to reduce calorie and nutrient absorption. The limited quantity of food, combined with reduced absorption of calories, results in faster and perhaps more pronounced weight loss than is normally achieved by the gastric banding procedure. This procedure usually requires a two- to three-day hospital stay, and normal activities can be resumed in four to five weeks.


Laparoscopic mini gastric bypass

Your stomach be divided into two pouches, an upper pouch and lower pouch. The lower portion of your small intestine is fused to the smaller upper pouch.  The creation of a smaller stomach pouch, which holds less than a cup of food, will help you get fuller quicker and feel fuller longer, and you will ultimately lose weight faster. By surgically resecting the small, upper pouch to the lower portion of your bowels, food will not be completely broken down, absorbed, or processed within your system prior to exiting your body
