Gastroscopy
An upper gastrointestinal endoscopy used to examine the oesophagus, stomach and duodenum.
→DIAGNOSTICColonoscopy
An endoscopic examination of the colon that can identify and often remove polyps during the same procedure.
→DIAGNOSTICHigh-resolution Oesophageal Manometry
Measures oesophageal contractions and sphincter relaxation to evaluate achalasia and other motility disorders.
→DIAGNOSTICMRCP
A non-invasive MRI technique focused on the bile and pancreatic ducts.
→Minimally invasive treatment, for the right patient and the right reason.
Every procedure guide goes beyond “what is it?” to cover suitability, preparation, procedure day, risks, alternatives and follow-up.

EVIDENCE-BASED GASTROENTEROLOGY.
PATIENT-CENTRED CARE.
In advanced endoscopy, technical skill matters alongside appropriate indication, evidence, honest discussion of alternatives and helping the patient understand the journey. The clinical profile is presented together with international meetings, live cases, teaching and scientific work.
Know what happens from the first question to follow-up.
If you are travelling for care, make the medical and practical pathway clear before you travel.
Share your records, understand the preliminary review, arrange an online consultation when appropriate and see the pathway from travel to follow-up at home.
