His role in your care pathway

The consultation helps us understand your situation and discuss whether surgery may have a place among the possible treatments. Any operation is decided collectively by the multidisciplinary team, with you. Medication, nutritional support and physical activity may also be part of your care pathway.

Surgery and innovation

Robot-assisted surgery is one of the techniques used to perform certain operations. Whether it is used depends on the operation and on your situation.

Dr Fournier is a proctor (trainer) for the robot-assisted surgery platform used at Hôpital de Nyon: he supports other surgeons as they learn this technique³.

In Nyon, including when a specialist referral centre is needed

You can be welcomed and supported at the Centre in Nyon, including when your BMI is over 50. Your assessment, preparation and follow-up can be organised there. If your operation requires a specialist referral centre, we coordinate this step with the appropriate hospital. Wherever possible, and with the agreement of the host centre, Dr Pierre Fournier performs your operation there himself.

Depending on your situation, the appropriate hospital may be a specialist referral centre in Geneva (HUG), Lausanne or Neuchâtel.
