Gastric Bypass Marylebone, London

The gastric bypass or stomach bypass is one of the surgical techniques for treating morbid obesity. Alongside purely restrictive techniques, such as gastric banding, and largely malabsorptive techniques, such as Biliopancreatic Derivation by Scopinaro, this is a combined technique. As with a purely restrictive intervention such as the adjustable gastric band, this surgery is largely a restriction of the food intake, with reduced digestion a less important factor. However, the long-term results are noticeably better than those for purely restrictive surgery. This is due to reduced food intake and a reduced feeling of hunger.

In this procedure, a hollowband made of special material is placed around the stomach near its upper end,creating a small pouch and a narrow passage into the larger remainder of thestomach. The band is then inflated with a salt solution. It can be tightened orloosened over time to change the size of the passage by increasing ordecreasing the amount of salt solution. The entire procedure is donelaparoscopically, where a laparoscope is inserted through the abdominal wallthrough small surgical incisions. It induces weight loss byreducing the capacity of the stomach, which restricts the amount of food thatcan be consumed. Minimally Invasive Approach

The gastric sleeve is the latest weight loss procedure that shows promising results. By restricting food absorbtion and reducing hunger the gastric sleeve might be your best option. Advantages of gastric sleeve include lower cost, less dumping, fewer complications and does not require adjustments after the initial surgery. How does the Gastric Sleeve work? The vertical sleeve gastrectomy is a restrictive form of weight loss surgery in which approximately 85% of the stomach is removed leaving a cylindrical or sleeve shaped stomach with a capacity ranging from about 60 to 150 cc, depending upon the surgeon performing the procedure.

Gastric sleeve surgery, or a laparoscopic sleeve gastrectomy, is a surgical procedure during which a part of the stomach is removed leaving the remaining part to function as a new smaller stomach. The stomach is an organ which functions as a temporary food reservoir and it also produces hormones, such as gastrin and ghrelin. Ghrelin is associated with the feeling of hunger. Therefore, the removal of a large portion of the pouch can favorably alter the hunger hormone production. After a gastric sleeve procedure a patient’s food intake is decreased and they feel full faster. It is a bariatric surgery, which helps patients to lose as much as 50 to 70 percent of their excess weight.

A gastric bypass is one of the techniques used in bariatric surgery and is done not only to kick-start  the weight loss process, but also to prevent or treat health problems that are associated with excess weight. Even though obesity has been prevalent for ages, only recently has it been recognised as a disease of multifactorial origin. The first attempts to treat obesity for the sole purpose of weight loss began in 1950s, when jejunoileal bypasses were done to induce a state of malabsorption (a condition when nutrient absorption is impaired). Despite reaching desired weight loss results, the procedure had too many post–operative complications to be deemed successful. The gastric bypass was developed years later, in the 1960s. The surgical technique went through numerous modifications in order to decrease the number of complications and is now one of the most frequently performed bariatric surgeries worldwide.

An adjustable gastric band, often called the band, is a bariatric surgery which helps patients lose as much as 40 percent of their excess weight. It is a minimally invasive, reversible and adjustable procedure. Food consumption is decreased by placing a silicone device (the so called band) around the top portion of the stomach. Its tightness can be adjusted by inflation or deflation through a port that is placed subcutaneously in the stomach.
