Using simulators to train surgeons makes them quicker and better, a Danish study has shown.
The research, published in the British Medical Journal, comes after Sir Liam Donaldson, England's chief medical officer, called for more simulation training in the NHS.
In his annual report in March, he said simulators "reduce errors and make surgery much safer".
The Royal College of Surgeons (RCS) has recently opened a new clinical skills unit, where a range of simulation techniques are taught, from simple plastic models, on which trainees can practice stitching, to a simulated operating theatre suite.
Butcher Joe Brennan, and trainee surgeon Mr Tom Palser, battle it out performing keyhole surgery in virtual reality. Prof Mike Larvin, Director of Education at the RCS, monitors their process.
