Gastric Bypass

Gastric bypass, a type of bariatric surgery (weight loss surgery), is a surgical procedure that alters the digestion process. Bariatric surgery is the only option that currently treats excessive obesity effectively in people who have failed more conservative measures such as diet, exercise and medications. The gastric bypass is the oldest operation.

Gastric bypass Gastric bypass is a mixed surgical technique, which benefits from gastric restriction through a section of the stomach along the lower curvature of the stomach, allowing the patient to feel satisfied with less amount of food and, At the same time, it benefits from poor intestinal absorption by associating a derivation of food so that they do not pass through the first intestinal loops and there is a lower absorption of nutrients and calories. In this way, the mechanisms of weight loss are more effective and perpetuate over time, keeping patients as close to their normal weight as possible.

 

Gastric Band

Gastric band Restrictive gastric operations, such as the procedure with adjustable gastric band, serve only to restrict and decrease food intake and do not interfere with the normal digestive process.

In this procedure, a hollow band made of a special material is placed around the stomach near its upper end, creating a small bag of approximately 15 ml capacity, and a narrow duct within the largest remaining portion of the stomach. This small duct slows the emptying of food from the bag and produces a feeling of fullness.

The gastric band can be tightened or loosened over time to change the size of the duct. Initially, the bag contains about 28 grams (1 ounce) of food and subsequently expands from 57 to 85 gr (2-3 ounces).

White gastric band The adjustable gastric band is a silicone ring with an inflatable chamber inside that is going to be connected to a device that allows to modify its internal diameter. It is a device that is NOT visible from the outside and that does NOT cause discomfort, even after weight loss. This device allows to adjust the internal diameter of the gastric band according to the need of each patient.

 

Gastric Sleeve

Also called tubular gastrectomy, sleeve gastrectomy or gastric sleeve. It is a procedure, restrictive, by laparoscopy, relatively new which results in the decrease in food intake, which induces weight loss.

Previously it was used in patients with high risk of operative morbidity and mortality, or with superobesity, with body mass indexes (BMI) of 60 or more, as a first stage of treatment, considering a second subsequent surgical treatment, according to weight loss of the patient.

It is currently indicated in any type of obesity and even in patients with Diabetes Mellitus (NIDDM or type 2) that is not of long evolution, less than 10 years; since it has been seen that post-surgery glucose levels normalize without the need for diabetes medications. And in many cases diabetes remits with this type of surgery, not because of losing weight, but because of the decrease in hormonal action produced by food intake.
