Dr Fraser performs a number of different types of specialised endoscopic procedures. These are performed in state of the art endoscopy units in premier Edinburgh hospitals using the latest equipment and expertly trained nurses.


This is a form of endoscopy when an endoscope (also known as a gastroscope) is passed through the mouth and oesophagus (gullet) into the stomach. A local anaesthetic throat spray is often used with or without short acting sedation to make the procedure, which lasts only 8-10 minutes, more comfortable. Gastroscopy is an excellent test for the investigation of acid reflux, dyspepsia (indigestion), possible hiatus hernia, when stomach ulcers are suspected or if biopsies need to be taken (e.g. duodenal biopsies to look for coeliac disease).

 Indications for gastroscopy

  • For the investigation of heartburn caused by acid reflux, indigestion (dyspepsia), difficulty swallowing (dysphagia), painful swallowing (odynophagia), upper abdominal pain or weight loss (for possible stomach ulcers or cancer), anaemia and gastro-intestinal bleeding
  • Surveillance of patients with Barrett’s oesophagus
  • Take biopsies (Barrett’s oesophagus, Helicobacter pylori, coeliac disease)
  • To perform therapy (balloon dilatation of strictures and achalasia, botox injection, endoscopic mucosal resection, polypectomy)
  • To assess the anatomy of the stomach (for hiatus hernia or before anti-reflux surgery)
  • To investigate abnormalities seen at x-ray (after barium swallow)
