Referral details

Gastroenterolgy referrals

Referrals are welcomed from local GPs and tertiary referrals from any other hospital. All patients are referred by letter from their GP or from other specialists seeking a further opinion. Referrals can also be made via choose and book (CAB).

The centralisation of colorectal services has not changed the referral patterns for GPs or other referrers to the service. Patients can continue to be referred to a particular consultant at a particular hospital. To avoid delay GP referrals should be addressed to a colorectal consultant surgeon or a named consultant surgeon.

Please note, the endoscopy dept at the Royal Free Hospital does not accept direct access referrals to the endoscopy department. However, GPs can refer to the one-stop dyspepsia clinic for direct access upper gastroscopy procedure via paper or CAB referrals.

Referrals to the gastroenterology team will be reviewed by a clinician and one of the following next steps will take place:

  1. You will receive an out-patient appointment at one of our hospitals
  2. You will receive an appointment for a test or an investigation before your first out-patient appointment. This will mean faster diagnosis and treatment
  3. You and your GP will receive a letter explaining how best to manage your symptoms. One of our clinicians has reviewed your symptoms and does not think you need to attend an out-patient appointment

A referral from your GP will not automatically lead to an out-patient appointment at one of our hospitals. Further information about what to expect when you are referred to the Royal Free London can be found on our out-patient page.

If you have any questions about your referral, please contact:

Louise Ryan referrals

The majority of gastrointestinal physiology tests are not first line tests and patients will usually already be under the care of consultant within one of our hospitals.

We accept referrals from other hospitals using our referral form (link coming soon) or a referral letter which provides the essential information. Our preferred method of receipt is by secure email (NHSmail) as this is the quickest route. Referrals can also be faxed to 020 7830 2923 or sent by post.
