Adjustable gastric banding surgery

Adjustable gastric banding is a surgical operation intended for weightloss in obese people with a Body mass indexof at least 35 (obesitystarts at BMI 30). It is best done laparoscopically (see : laparoscopy) under general anesthesia. Usually , it takes about one hour. It consists in inserting a hollow plastic band around the stomach.This band is connected by a tubulure to a small box implanted in the abdominal wall. You can constrict the band by filling the box with physiologic serum . Band constriction has a restrictive effect on gastric filling capacity and forces the patient to lower his food intake and it can be modulated by emptying or filling the box with a percutaneous needle. This operation is practised only if the patient is highly motivated for changing his eating habits and after a psychiatric assessment. Like any other surgical procedures , it has risksan side-effects : failure , implant infection , gastric perforation , intra-gastric migration. For very severe obesity ( BMI > 50) gastro-jejunal bypassis indicated in the first place.
