Gastric Bypass

Technical bypass , it presents a difference, because in addition to reducing the size of the stomach, the surgeon creates a kind short circuit causing food food restriction and malabsorption.

Doctors believe that this operation is a success only when their patients recover from morbid obesity, that is to say when they lose, in the eighteen months after the operation, half of their excess weight. This is what happens in 70% of cases. Patients are left with a BMI below 35.

This procedure has a dual role: it treats morbid obesity because it allows a reduction of 70% of excess weight over a period of 12 to 18 months and latest discovery: it can definitely treat type 2 diabetes by its hormonal effects.

In the technique of bypass, open the stomach, the digestive tract and then cut the suture. If healing is bad gut sutures are leaking and gut contents may be found in the abdominal cavity. In this case, an appropriate treatment will be quickly implemented.

Our team has completed more than 800 Bypass, with an average hospital stay of 3 days.

Bypass gastrique-eng
principle Technical restrictive and malabsorptive which decreases the volume of the stomach and slows the passage of food. it reduces both the amount of food ingested (the size of the stomach is reduced to a small pouch) and the assimilation of these foods in the body, with a short circuit of a portion of the stomach and intestine (no organ is removed). Food will directly in the middle part of the small intestine and are therefore treated in smaller quantities.
Weight loss expected Of the order of 70 to 75% of excess weight, which corresponds to a weight loss of about 35 ¹ to 40 kg. The decline of these results is 20 years.
Average duration of the intervention² 1:30 to 2 hours
Mean duration of hospitalization³ 3 to 5 days
Mortality intervention 0.5%
Principal risks of complications
  • Surgical complications: ulceration, leaks or narrowing at the junction between the stomach and the intestine, hemorrhage, obstruction of the intestine;
  • Nutritional deficiencies;
  • Functional complications: hypoglycemia after eating, dumping syndrome * diarrhea.

¹. For a person of average height (1.70 m) with a BMI equal to 40 kg/m2.
². In the absence of complications during intervention.
³. In the absence of complications after surgery.
*. Dumping syndrome : feeling sick (with palpitations, headache, nausea, diarrhea …) that can occur just after a meal. This syndrome is caused the massive and rapid in the gut of foods rich in fats or sugars.

 In our experience, we realize now type 2 Bypass:

¹. Bypass Y, with 2 short circuits (stomach - intestine - and gut-gut)
