(Gastric sleeve, Sleeve gastrectomy, gastrectomy in tube). Consists of removing up to 85% of the stomach. Should be done laparoscopically by a video camera that is inserted into the abdomen through a few small incisions and a special surgical forceps.

During the first few weeks should eat only liquids to go used the stomach.

During the first year may reach up to 80% of losing excess weight. Usually, a normalization of cholesterol and blood pressure after a few months.

The gastric bypass procedure is a type of Bariatric Surgery or weight loss surgery.

Produces an improvement in mobility and quality of life. Thus, will reduce all diseases associated with obesity: Diabetes, hypertension, high cholesterol, etc.

Changes that must be made before the surgery include:

  • Quit smoking.
  • Don’t drink alcohol.
  • Lose some weight.

Is a complex procedure, under general anesthesia. The surgery time is 3 to approximately 4:0, followed by a relocation of 2 to 5 days in the hospital.

Performed laparoscopically, produces less scarring and allows you to recover more quickly than traditional open surgery. During the surgery, we form a small stomach pouch and a part of the small intestine is attached to this miniestômago. This connection is called anastomosis.

At Clínica Luso Espanhola we are in favour of holding of a by-pass with a single anastomosis, in order to avoid complications.

During the first year may reach up to 80% of losing excess weight.

As the food won’t go through the whole intestine, absorption of foods is greatly reduced.

Post-surgery treatments include a general diet plan and regular exercise. In some cases it may be necessary to take vitamin supplements.



The cost of this surgery can exceed € 10.000.



It has been converted into a very attractive technique for patients and physicians due to several factors. This is a new form of surgical treatment of obesity that does not require cutting the digestive tract or introducing a band around the stomach.




  • Bad welding of anastomosis that gives way to fistula.
  • The bleeding caused by the Court.

In the case of these bands may perforate the stomach, especially if you tighten too much.

The gastroplicatura uses another principle by which reduces risks of erosion or fistula. It is also slightly more surgery than previous economic due to less time in surgery and prosthetic material free (band).

Similarly you can sew a garment, also the stomach can be sewn, decreasing its size. The stitches are given in gastric wall without the need for the cut. Even when the points are tied, the stomach is still “closed”.

The innermost layer called gastric mucosa is not exposed.


The slimming of the patients who have the Gastroplicatura has been shown to be identical to that of patients who undergo vertical gastroplasty. Weight loss in Plication is bigger than produced by Gastric Band.



  • Don’t cut yourself part of the stomach, thus avoiding the leakage or fistula.
  • The lack of cuts avoids the risk of bleeding.
  • The lack of prostheses (always a foreign body) avoids the risk of gastric perforation.
  • Absence of risk of vitamins or iron deficiencies caused by the loss of a part of the stomach.
  • The stomach can continue to be watched in case of illness through digestive endoscopy.
  • The surgery is more easily reversible than other techniques for not be crippling.
  • Needs no adjustments as in the case of the Gastric Band.
  • Sick time is quite short.
  • Physical activity can be resumed more quickly.
  • Mortality is less than in other gastric surgeries.
  • If it is not enough to treat the problem there is always the possibility of a more aggressive surgery later.



  • A procedure less tested.
  • There are still no long-term data maintenance of the weight lost.
