The procedure involves placing a rigid ring around the upper part of the stomach, preventing it from stretching when food reaches it. The feeling of fullness occurs more quickly. The ring is connected to a small reservoir under the skin. The band can be tightened or slackened by injecting serum into the reservoir.

Advantages

  • expected weight loss of between 40% and 75% of excess weight, i.e. weight loss of approximately 20 kg to 30 kg for a person of average height (1.70 m) with a BMI of 40 kg/m²
  • reversible technique (N.B. if the gastric band is removed, the patient often regains weight)

Disadvantages of the surgery

  • procedure-linked mortality rate is 0.1% (source: HAS)
  • regular X-rays required
  • comfort is very variable when eating and patients frequently show low tolerance (food blockages, vomiting, oesophageal pain)
  • limited duration of efficacy: weight gain is observed when the band is removed
  • complications are possible, even after several years:
    • problems linked to the reservoir (infection, movement, pain etc.)
    • the band can slide, dilating the pouch (causing severe vomiting and eating to become impossible)
    • lesions in the stomach and oesophagus: ulcers, œsophagitis, dilation of the oesophagus
    • having already had a gastric band increases operating risks if another form of gastric surgery is undertaken at a later date
