Two-year outcomes of prehabilitation among obese patients with ventral hernias. A randomized controlled trial (NCT02365194).

All obese patients with a ventral hernia were offered surgery once they had lost 7 per cent of their body weight, or had no weight gain after six months. The addition of a prehabilitation programme did not reduce the rate of perioperative complications (10.2 versus 9.1 per cent, P=0.4), or increase the number of hernia-free patients after two years: 72.9 versus 66.1 per cent, P=0.42, in this study that included 118 patients.

Comment: Either wrong programme or wrong type of patient.
