The Endoscopy Suite

The endoscopy suite is a modern suite in the Riverside treatment centre, with three procedure rooms and ample facilities for one-to-one consultation.

We offer a variety of inpatient and outpatient diagnostic endoscopy tests, including colonoscopy, flexi sigmoidoscopy and gastroscopy.  We also perform a wide number of therapeutic interventions including PEG insertion, oesophageal stenting, balloon dilatation and endoscopy therapy for acute gastrointestinal bleeding.

The suite has a full range of facilities including video-endoscopic equipment.  It has been externally recognised and certified to meet the highest standards relating to clinical audit and training as well as patient safety and experience.  All patients are seen within the national guidance waiting times.  We have advanced endoscopic techniques and equipment to minimise discomfort during colonoscopy and for upper GI endoscopy, we provide sedation if requested.

All endoscopy procedures are performed or supervised by consultants, and there are three endoscopist practitioners, two of whom have achieved national prominence or won national awards. The specialist nursing team is trained to support the clinicians carrying out the endoscopic procedures, to look after patients during the recovery stage and to provide a high standard of support and guidance for patients and their relatives.
