Hepatobiliary and General Surgeon
Most patients are referred by their general practitioners or other specialists.
When you come to your appointment, I will ask questions about your illness and examine you to try to determine or confirm the diagnosis. This process may also require a number of tests (e.g. blood tests, x-rays, scans etc). Often you may have already had investigations such as CT scans and if you are able to bring these with you it will be of great help. In addition, copies of any medical records or test reports can also be of assistance. Sometimes this can all be done during one visit, but for some conditions this will take several follow-up appointments. Occasionally some tests are arranged even before your appointment to try to speed up the process.
