The "Y de Roux" gastroplasty, or also known as Gastric Bypass, is the current gold standard procedure for bariatric surgery by the SBCBM (Brazilian Society of Bariatric and Metabolic Surgery). It is one of the most performed weight loss procedures in Brazil. In this procedure, stapling creates a small (15 to 20 cc) stomach pouch. The rest of the stomach is not removed, but completely stapled and separated from the stomach pouch. The exit from this formed pouch passes straight to the underside of the jejunum, thus diverting food absorption. This diversion is done by dividing the small intestine shortly after the duodenum, in order to take it to the stomach and build a connection (anastomosis – connection) with the formed stomach pouch. The other end is attached to the side of the bowel Roux Y loop, creating the "Y" shape that gives the technique its name. The length of one of the bowel segments can be increased to produce lower or higher levels of malabsorption.

Benefits

​

 

  • The average for excessive weight loss, after the procedure of Gastroplasty and “Y de Roux” derivation, is generally higher in a compliant patient than after the pure restrictive procedure;

  • One year after surgery, weight loss can reach 77-100% of excess body weight;

  • Studies show that after 10 to 14 years, 50-60% of excess body weight loss was maintained by some patients;

  • demonstrated  that 70-90% of certain associated health conditions  (back pain, sleep apnea, high blood pressure, diabetes and depression) were improved or resolved;

  • Theoretically it can be reversed.

Scratchs

​

 

  • As food is diverted from the duodenum, all of the risk considerations discussed in the prior art with derivation on malabsorption of some minerals and vitamins also apply to this technique, only to a lesser degree;

  • A condition known as, "rapid emptying syndrome" can occur as a result of the rapid emptying of stomach contents into the small intestine. This is sometimes triggered when too much sugar or too much food is eaten. Although not considered a serious risk to your health, the results can be very unpleasant and include nausea, weakness, sweating, frailty and occasionally diarrhea after meals. Some patients are unable to eat any form of sweets after surgery;

  • The deviated part of the stomach, duodenum and segments of the small intestine cannot be easily visualized using an x-ray or endoscopy if problems such as ulcers, bleeding or malignancy occur.
