General Surgery

We provide the whole range of surgical gastroenterology, performing a high volume of routine general and specialist gastrointestinal surgery. We are also busy acute emergency surgical service. We provide a specialist in-house referral service for routine and emergency gastrointestinal surgical problems, and are available for referrals both from our medical colleagues and also other surgical specialties.

The general surgical department for the Trust consists of five full time consultant gastrointestinal surgeons (Mr Peter McDonald, Mr Stuart Gould, Mr Raj Bhutiani, Mr Alberto Isla and Mr Anthony Antoniou). The service is supported by four specialist registrars in general surgery and two experienced clinical fellows.
