Due to the consequences of pathological obesity on morbidity and morta
lity, the weight problems of such patients need to be treated energeti
cally. It is legitimate to consider surgical treatment following repea
ted failure of medical management. Due to its potential consequences o
n the patient's nutritional status and lifestyle, obesity surgery can
only be performed by complying with strict selection criteria and by u
sing the least aggressive techniques, i.e. gastroplasty. A new techniq
ue, gastric cerclage, appears to be promising in this context more. Be
cause of the risk of weight resumption after the operation, surgery mu
st be integrated into a more global approach, essentially based on nut
rition, psychotherapy and physical activity.
