Gastroenterology is where the digestive system and its disorders are studied. Hepatology incorporates the study of the liver, gallbladder, biliary tree and pancreas, as well as the management of their disorders.

We offer a general gastroenterology and hepatology service in addition to a number of speciality services outlined below.

In addition we treat viral hepatitis - a dedicated viral hepatitis clinic is run on a Monday afternoon. There is also a nurse-led clinic for viral hepatitis (Thursday morning) which receives direct referral for assessment, monitoring and treatment of hepatitis B and C from primary care and various departments within the hospital including ante natal, fertility and department of sexual health.

Upper gastro-intestinal

Making an appointment
Patients are referred by their GP or by a hospital consultant and are seen in the outpatients department. Appointments can be made by you or your GP via The Electronic Referral Service (e-RS)

If a GP suspects upper GI cancer, a patient will receive a fast-track referral through the system, via our cancer referral office. 

Routine investigations

There are a variety of tests that can diagnose cancer and they will depend on the specific symptoms experienced by the patient. The common investigations undertaken are:

  • endoscopy, uses a thin, flexible telescope to look into the upper part of the gut (oesophagus, stomach and duodenum) for any abnormalities
  • endoscopic ultrasound, a method of combining endoscopy and ultrasound imaging to obtain high quality images of the digestive tract
  • CT (computerised tomography) scan, uses x-rays to take images of the body at different angles, they are more detailed that normal x-rays
  • endoscopic retrograde cholangiopancreatography (ERCP), examines the ducts (drainage routes) of the gall bladder, pancreas and liver (the drainage routes of the liver are known as bile ducts)
  • ultrasound scan, is an investigation that uses sound waves to build up a picture of the inside of the body.

Some investigations may take place prior to the outpatient appointment.

What to expect
There are various treatments available, depending on the type of cancer. Patients who need surgery for their cancer will be seen at Homerton or referred to the Royal London Hospital. Chemotherapy and radiotherapy treatment will take place at St Bartholomew’s Hospital.

Ongoing support
There is a designated upper gastro-intestinal nurse specialist who supports patients throughout their investigations and treatment.
We have a Macmillan cancer information manager who provides support and advice for all patients who are diagnosed with upper gastro-intestinal cancer.
