Diagnostic Gastroscopy

A diagnostic gastroscopy is a procedure used to diagnose problems with your upper digestive tract. This procedure may be recommended if you are experiencing new or ongoing symptoms and to inform which specific treatments may help.

What is a diagnostic gastroscopy?

A gastroscopy uses a thin flexible tube with a light and camera attached to view the fist part of your upper digestive tract. This includes your oesophagus, stomach and the first part of your upper intestine. The instrument used is called an endoscope and the terms endoscopy and gastroscopy are often used interchangeably to refer to the same procedure. It can also be used to take a biopsy, where small samples of tissue are removed for testing.

Why do I need a diagnostic gastroscopy?

Your GP may refer you for a diagnostic gastroscopy to investigate symptoms including persistent abdominal pain, anaemia, reflux, difficulty swallowing (dysphagia), nausea or vomiting. Dr Hopkins is experienced in detecting inflammation, ulcers or abnormal growths in your gastro-intestinal tract and diagnosing the underlying cause of your pain or symptoms.

The types of conditions that may be identified using a diagnostic gastroscopy include:

• Gastro-oesophageal reflux disease (GORD)

• Inflammation, ulcers and non-cancerous growths (polyps)

• Hiatus hernia

• Disorders that cause difficulty swallowing (such as achalasia or dysphagia)

• Cancers including oesophageal and gastric cancer

• Gastro-intestinal stromal tumours (GISTs)

• Narrowing of the oesophagus (oesophageal stenosis)

How do I prepare for a diagnostic gastroscopy?

You will need to have an empty stomach for your diagnostic gastroscopy to ensure Dr Hopkins can clearly see all areas of your stomach and upper digestive tract. This means no food or drink at least six hours before your procedure. Dr Hopkins will provide instructions about your preparation and what to expect during and after your procedure.

Step by step: diagnostic gastroscopy

• A diagnostic gastroscopy is performed using light sedation called twilight anaesthetic to ensure you are relaxed and comfortable.

• A thin flexible tube (endoscope) will be inserted into your mouth and then into the oesophagus, stomach and first part of the small intestine (duodenum) to view these areas.

• Diagnostic gastroscopy usually takes 15 to 30 minutes.

• You will be able to eat and drink as normal soon after the procedure.

• You may feel drowsy so will need a friend or relative to take you home.

Dr Hopkins will see you after your procedure to discuss the findings. You will also be given a report to take home and instructions about any follow up appointments or procedures required.
