Gastric By-pass

Gastric By-pass

What is Gastric By-Pass Surgery?

The stomach is divided into two parts by means of automatic devices called staplers, in such a way as to leave a stomach volume equal to the volume of a medium-sized tangerine. This small stomach part is then connected to a point 2 meters ahead of the small intestine. By this way the possible food intake is limited because the stomach can be filled with contents of 25-30 ml. Moreover, since foods will be delivered to a point 2 meters ahead of the small intestine, the absorption of foods will be reduced by 30%. By this means, a weight loss is achieved.

Its advantages:

  • Fast weight loss.
  • Weight loss that can continue for a period up to 2 years after surgery.
  • Very low possibility to regain weight in the long term after surgery.

Its complications:

General complications

  • Allergic reaction due to drugs
  • Transmission of diseases due to blood transfusion
  • Heart attack, renal failure, urinary tract infection, pulmonary (lung) infection.
  • Rarely death (0,2%)

Complications specific to the procedure

  • Organ injury during surgery
  • Leakage from the stapler line (0,5-7%)
  • Stenosis in the gastro-intestinal connection
  • Dehydration
  • Gastric ulcer
  • Increased risk of gallstone formation due to fast weight loss
  • Dumping syndrome (vomiting, reflux, diarrhea)
