Minimum Excess Weight Required for Obesity Surgery: how far can we go?

The classical indication for obesity surgery, in terms of excess weight, included only patients with an excess weight of 100% or 45 kg. This review challenges this classic indication. Sixty-four out of 170 patients treated with a biliopancreatic diversion had an excess weight below 80%. The specific weight-related complications, reoperations and results are compared with patients above 80% excess weight. The different groups are comparable in complications and results.
