Gastroscopy in Melbourne
Gastroscopy is a minimally invasive procedure that allows direct visualisation of the upper digestive tract, including the oesophagus, stomach, and duodenum, using a thin, flexible instrument called a gastroscope equipped with a high-definition camera.
It is the most accurate method for diagnosing conditions of the upper gastrointestinal tract, from peptic ulcers and Barrett’s oesophagus to upper gastrointestinal bleeding and early-stage cancer.
At Specialist Surgical Group, our Melbourne-based gastrointestinal and upper GI surgeons perform gastroscopy for patients with persistent upper digestive symptoms, those requiring surveillance for known conditions such as Barrett’s oesophagus, and those needing therapeutic interventions, such as the treatment of bleeding ulcers or the dilation of narrowed areas.
We consult from our Essendon and Bundoora clinics, with procedures performed at accredited hospitals in Melbourne. Gastroscopy is part of our broader endoscopy service, which also includes colonoscopy for the investigation of the lower bowel.

Is gastroscopy for you?
Gastroscopy is generally recommended if you:
- Have persistent heartburn, acid reflux, or symptoms of gastro-oesophageal reflux disease (GORD) that have not responded to initial treatment
- Experience difficulty swallowing (dysphagia) or a sensation of food sticking in the throat or chest
- Have unexplained upper abdominal pain, persistent nausea, or vomiting
- Show signs of upper gastrointestinal bleeding, such as dark or tarry stools, vomiting blood, or unexplained iron deficiency anaemia
- Have a known diagnosis of Barrett’s oesophagus or gastric polyps requiring scheduled surveillance
- Have a personal or family history of stomach cancer or oesophageal cancer that warrants periodic screening
- Need confirmation of Helicobacter pylori eradication following treatment
Your suitability will be confirmed during a consultation, where we will review your symptoms, medical history, and current medications to determine whether gastroscopy is the most appropriate next step.
Potential benefits
- Precise diagnosis of upper digestive conditions. Gastroscopy provides direct, high-definition visualisation of the oesophagus, stomach, and duodenum, enabling accurate diagnosis of conditions including gastritis, peptic ulcers, oesophagitis, Barrett’s oesophagus, and upper gastrointestinal tumours. It is the reference standard for upper GI endoscopic quality and diagnostic performance [1].
- Early detection of cancer and precancerous changes. Regular surveillance gastroscopy can identify precancerous changes in the oesophageal lining (dysplasia) associated with Barrett’s oesophagus at a stage when endoscopic treatment is curative, significantly improving survival outcomes compared with late-stage diagnosis [2].
- Targeted biopsy and H. pylori testing. Tissue samples can be collected from any suspicious area during the same examination, allowing pathological diagnosis and accurate H. pylori testing from gastric biopsies. This guides targeted antibiotic therapy without the need for a separate procedure [3].
- Therapeutic interventions during the same examination. Many conditions can be treated at the time of diagnosis, including endoscopic haemostasis for bleeding peptic ulcers, removal of small polyps, and dilation of oesophageal strictures. This avoids the need for separate surgical procedures in the majority of cases [4].
- Safe and well-tolerated with a low complication rate. Gastroscopy is one of the most commonly performed endoscopic procedures worldwide. In experienced hands and with appropriate patient selection, it carries a very low rate of serious adverse events [1].
Potential risks
- Sedation-related effects. Conscious sedation can cause temporary drowsiness, nausea, or a transient drop in blood pressure. Serious cardiorespiratory complications are uncommon and are minimised by careful pre-procedure assessment, appropriate sedation dosing, and continuous monitoring throughout the examination [6].
- Throat soreness and temporary discomfort. Mild throat soreness, hoarseness, or a sensation of bloating from air introduced during the examination are common and typically resolve within 24 hours. These are expected minor effects rather than complications [6].
- Bleeding after biopsy or therapeutic intervention. Minor bleeding following a biopsy is usually self-limiting. Clinically significant bleeding is uncommon and is more likely in patients taking anticoagulant or antiplatelet medications. Medication management instructions will be provided before your procedure [4].
- Perforation. Injury to the oesophageal, gastric, or duodenal wall is a rare but serious complication, occurring in fewer than 1 in 2,500 diagnostic gastroscopies. The risk is higher during therapeutic procedures such as dilation of strictures or endoscopic resection [5].
- Aspiration. Inhaling stomach contents into the lungs is a rare risk, particularly in patients who have not fasted adequately or who have a condition that delays gastric emptying. Strict fasting requirements before the procedure are in place to minimise this risk [6].

Your gastroscopy journey
The following steps provide a brief overview of your gastroscopy journey. Individual experiences will vary based on your specific health circumstances.
1. Initial consultation and health assessment
Your surgeon will review your symptoms, relevant investigations such as prior endoscopy reports or imaging, and your medical and family history. Any risk factors for upper gastrointestinal conditions, including a family history of oesophageal or gastric cancer, will be noted.
Your current medications will also be reviewed. Blood thinners, NSAIDs, and proton pump inhibitors may need to be adjusted before the procedure. Clear written instructions will be provided at your consultation.
2. Pre-procedure preparation
Gastroscopy does not require bowel preparation. You will need to fast from solid food and milk for at least 6 hours before the procedure, though clear fluids are generally permitted up to 2 hours beforehand. An empty stomach is essential for both safety and a clear view of the stomach lining.
Detailed fasting and medication instructions will be provided in advance, including tailored guidance for patients with diabetes or taking blood-thinning medications.
3. Sedation and positioning
You will be admitted to an accredited Melbourne hospital or day procedure facility, where conscious sedation is administered through an IV line and a protective mouthguard is placed. The examination takes 15-30 minutes.
Once sedated and positioned on your left side, your surgeon guides the gastroscope through the mouth and throat into the oesophagus, advancing it through the stomach and into the first part of the duodenum (the pylorus). The entire lining is examined on both the forward and withdrawal passes.
Targeted biopsies are taken from any suspicious areas, and therapeutic interventions, such as haemostasis of a bleeding ulcer, polyp removal, or dilation of a stricture, are performed in the same examination where needed.
4. Recovery and discharge
You will be monitored in the recovery area for 1-2 hours while the sedation wears off. Mild throat discomfort or bloating from the air used during the examination is common and resolves quickly. Preliminary findings will be discussed with you before you leave.
You will need a responsible adult to drive you home and should avoid driving, operating machinery, or making significant decisions for the rest of the day.
5. Results and follow-up
Preliminary findings are discussed before discharge. Biopsy and pathology results are typically available within 7-10 days and will be communicated to you and your referring doctor.
If Barrett’s oesophagus is identified, your surgeon will explain the degree of any dysplasia and your recommended surveillance interval, which may range from 2 years for non-dysplastic Barrett’s to 3 months for confirmed high-grade dysplasia [1].
Follow-up appointments will be coordinated through our clinic.

The cost of a gastroscopy in Melbourne depends on your private health insurance, the clinical indication, and the complexity of the procedure. As a Medicare-eligible procedure, gastroscopy attracts a rebate when performed for an appropriate indication. For privately insured patients with suitable hospital cover, out-of-pocket costs are often low.
For self-funded patients, indicative costs typically range from $800-$1,800 after the Medicare rebate, depending on whether therapeutic interventions are performed. Your specific out-of-pocket costs will be confirmed in writing before your procedure. We recommend contacting your insurer before your appointment to confirm your level of cover.
Yes. You will need to fast from solid food and milk for at least 6 hours before the procedure. Clear fluids such as water, black tea, or coffee are generally permitted up to 2 hours before the procedure.
An empty stomach is essential for both safety, as it reduces the risk of aspiration, and diagnostic quality, as food residue can obscure the view of the stomach lining. Detailed fasting instructions will be provided at your consultation.
Most patients receive conscious sedation, which makes them relaxed and drowsy, largely unaware of the procedure while still able to respond to instructions. Some patients choose to proceed without sedation, which is feasible for a standard diagnostic gastroscopy but less comfortable.
General anaesthesia is used in specific circumstances, such as for complex therapeutic procedures or in patients for whom conscious sedation is not appropriate. Your preferences and any concerns about sedation can be discussed at your consultation.
The examination itself typically takes 15-30 minutes, though this may be longer if biopsies are taken or therapeutic interventions are performed. Including admission, preparation, the procedure, and recovery, you should plan to be at the facility for approximately 2-3 hours. You will need a responsible adult to drive you home, as you cannot drive following sedation.
Mild throat soreness or a feeling of bloating is common and typically resolves within 24 hours. Some patients also notice mild hoarseness. These are expected minor effects of the procedure. Over-the-counter throat lozenges can help with any discomfort. If you experience persistent or worsening throat or chest pain, fever, or difficulty swallowing after you return home, contact our clinic promptly.
Findings visible during the examination will be discussed with you before you leave the facility. If biopsies were taken, complete pathology results are typically available within 7-10 days. Your surgeon or our clinic nurse will contact you with the results and discuss any next steps, including whether further treatment or a follow-up appointment is required.
Yes. Gastroscopy is a Medicare-eligible procedure when performed for an appropriate clinical indication. Relevant Medicare Benefits Schedule (MBS) item numbers apply depending on whether the procedure is diagnostic or therapeutic, and your surgeon will confirm which items are relevant to your case.
Private health insurance typically covers the hospital and anaesthesia component, subject to your level of cover and any applicable waiting periods. We recommend confirming your entitlements with your fund before your appointment.
Surveillance intervals for Barrett’s oesophagus depend on the length of the Barrett’s segment and the presence and degree of dysplasia. Current guidelines recommend surveillance gastroscopy every 3-5 years for patients with non-dysplastic Barrett’s oesophagus, with more frequent surveillance for those with confirmed low-grade dysplasia, and urgent review for high-grade dysplasia, which may warrant endoscopic treatment [2][7]. Your surgeon will recommend a personalised surveillance schedule based on your specific findings.
Gastroscopy examines the upper digestive tract, from the oesophagus through to the first part of the small bowel (duodenum), while colonoscopy examines the large intestine and rectum. They investigate different parts of the gastrointestinal system and are not interchangeable.
Some patients require both procedures, particularly when symptoms suggest pathology at multiple levels of the digestive tract. If both are recommended, they can often be performed on the same day under a single sedation episode.
Gastroscopy can diagnose a wide range of upper gastrointestinal conditions, including gastritis, peptic ulcers, Helicobacter pylori infection, Barrett’s oesophagus, oesophageal and gastric cancer, coeliac disease (via duodenal biopsy), and oesophageal strictures.
In the same examination, it can treat active ulcer bleeding, remove small polyps, dilate strictures, and retrieve swallowed foreign bodies. If gastroscopy identifies reflux-related damage or a hiatal hernia, your surgeon may discuss whether anti-reflux surgery is appropriate for your circumstances.
