The gastroenterology department deals with all aspects of general gastroenterology (digestive system) and hepatology (liver). This includes outpatient clinics and the management of inpatients.

We carry out endoscopies (a procedure used to examine the interior surfaces of an organ or tissue) at both Epsom and St Helier hospitals, with more complex therapeutic endoscopies, such as ERCP (endoscopic retrograde cholangiopancreatography) and stents, performed at St Helier. The department works closely with the gastrointestinal surgical department and specialist gastrointestinal radiologists.

Services offered include:

  • Gastroenterology outpatients
  • Virtual clinic where we review patients’ records and results and make management plan without seeing them
  • Hepatology - viral hepatitis , non alcoholic fatty liver disease, alcohol related liver disease, primary biliary cholangitis and primary sclerosing cholangitis, liver cirrhosis
  • Inflammatory bowel disease (IBD) services
  • Gastroscopy
