Gastroscopy.
A gastroscopy uses a thin flexible camera to examine the oesophagus, stomach and first part of the small intestine. It is one of the most important diagnostic tools for upper gastrointestinal conditions and is performed under light sedation.
A short, routine day procedure to examine the upper digestive tract.
A direct camera view of the upper digestive tract.
A gastroscopy (also called an upper GI endoscopy) involves passing a thin, flexible tube with a camera and light on the end through the mouth and down into the upper gut. It allows the surgeon to directly visualise the lining of the oesophagus, stomach and duodenum.
The procedure is performed under light anaesthetic sedation. It is very safe, takes approximately 10 minutes, and does not require an overnight admission. During the procedure, biopsies (small tissue samples) can be taken and certain conditions can be treated at the same time.
What you need to know before booking:
- A valid referral from your GP or specialist is required
- Once your referral has been received, our reception team will contact you to complete your booking
- Full preparation instructions, including fasting, medications and transport home, are provided below and confirmed at booking
When a gastroscopy may be recommended.
- Reflux or heartburn not adequately controlled with medication
- Upper abdominal pain or discomfort
- Difficulty swallowing (dysphagia)
- Nausea or vomiting
- Upper gastrointestinal bleeding or anaemia
- Unexplained weight loss
- Surveillance of Barrett's oesophagus
- Pre-operative assessment before upper GI or metabolic bariatric surgery
- Follow-up after treatment for oesophageal or gastric conditions
Before, during and after your gastroscopy.
Before the procedure
You will need to fast for at least 6 hours before your gastroscopy. Please let us know about any medications you take. You will need to arrange transport home, as you will not be able to drive after sedation.
During the procedure
A light intravenous sedative is given. Once you are comfortable, a thin flexible tube is gently passed through your mouth and guided through the oesophagus, stomach and into the duodenum. The procedure takes approximately 10 minutes.
After the procedure
You will recover in a monitored area until the sedation wears off. Most patients can go home within an hour or two. You may have a mild sore throat or feel bloated. Your surgeon will discuss findings with you directly after the procedure, and a written report will follow.
Biopsy results
If biopsies were taken during your gastroscopy, results are typically available within 1 to 2 weeks. Your surgeon or GP will contact you to discuss them and arrange any further steps.
Gastroscopy is often one part of a larger assessment.
Depending on your symptoms and findings, your surgeon may also recommend oesophageal manometry and a 24-hour pH study to fully assess the function of your oesophagus and the degree of acid exposure.
