Dr Jonathon Schubert
Gastroenterology & endoscopy

High quality endoscopy, with specialist expertise when it matters.

The majority of patients are referred for high quality gastroscopy and colonoscopy for screening, surveillance, investigation of symptoms and diagnostic gastroenterology. Dr Schubert also provides advanced endoscopic assessment and treatment for patients who require more specialised expertise.

About Dr Schubert

Precision, expertise and a specialist focus.

Dr Jonathon Schubert is a Consultant Gastroenterologist and Interventional Endoscopist with a particular focus on advanced diagnostic and therapeutic endoscopy.

Following specialist training in Gastroenterology and Hepatology in South Australia, Dr Schubert completed an Interventional Endoscopy Fellowship at the Royal Brisbane and Women's Hospital. He subsequently undertook further training in flexible endoscopic surgery and ESD in leading centres in Germany and Japan.

His practice includes the assessment and endoscopic treatment of complex mucosal lesions, selected early gastrointestinal cancers, large colorectal polyps, Barrett's-related neoplasia and other conditions requiring advanced endoscopic expertise.

Dr Schubert works closely with referring gastroenterologists, General Practitioners, surgeons, oncologists and multidisciplinary teams to determine the most appropriate approach for each patient.

He also has a background in Engineering and a PhD from the University of Adelaide focused on Helicobacter pylori and gastric cancer risk.

Areas of expertise

Gastroenterology, endoscopy & advanced endoscopy.

Referrals are welcomed for general gastroenterology, high quality endoscopy, screening and surveillance, as well as advanced endoscopic assessment and treatment.

01 / RESECTION

ESD & EMR

Advanced endoscopic resection of selected large, complex or superficially invasive gastrointestinal lesions.

02 / COLORECTAL

Complex colorectal polyps

Assessment and management of large or difficult colorectal lesions, including lesions referred for advanced resection.

03 / OESOPHAGUS

Barrett's oesophagus

Assessment, surveillance and endoscopic treatment of Barrett's-related dysplasia and neoplasia.

04 / EUS

Endoscopic ultrasound

Diagnostic EUS and selected tissue sampling for upper gastrointestinal and pancreaticobiliary conditions.

05 / SMALL BOWEL

Small bowel investigation

Capsule endoscopy and balloon-assisted enteroscopy for selected small bowel disorders and bleeding.

06 / GENERAL GI

General gastroenterology

Assessment of reflux, dysphagia, abdominal pain, altered bowel habit, iron deficiency, gastrointestinal bleeding and other gastrointestinal conditions.

07 / THERAPEUTIC

Dilatation & therapeutic endoscopy

Endoscopic dilatation for selected gastrointestinal strictures, together with other appropriate therapeutic interventions.

For patients & referring doctors

Advanced endoscopy when a more specialised approach is needed.

Most patients do not need advanced endoscopy. For selected lesions, however, techniques such as EMR and ESD can allow removal of significant gastrointestinal lesions without conventional surgery. These procedures require careful assessment of the lesion, its depth and its cancer risk.

EMR

Endoscopic mucosal resection

Removal of selected larger or complex mucosal lesions using an endoscopic technique, commonly in the colon and upper gastrointestinal tract.

ESD

Endoscopic submucosal dissection

A highly specialised technique allowing en-bloc removal of selected superficial gastrointestinal neoplasia, including lesions where conventional polypectomy or EMR may not be suitable.

EUS

Endoscopic ultrasound

Specialist ultrasound performed from within the gastrointestinal tract, including selected tissue sampling and assessment of upper gastrointestinal and pancreaticobiliary conditions.

BALLOON ENTEROSCOPY

Small bowel endoscopy

Deep enteroscopy for selected small bowel lesions, bleeding and other conditions identified through capsule endoscopy or other investigations.

Approach

High quality endoscopy and thoughtful care.

High quality endoscopy is the foundation of good gastroenterology — accurate examination, careful diagnosis and appropriate follow-up, with advanced techniques available when they are needed.

High quality examination

Careful, thorough endoscopy is central to screening, surveillance and the investigation of gastrointestinal symptoms and disease.

Advanced techniques when appropriate

For selected lesions, EMR, ESD, EUS, dilatation and other advanced techniques provide additional options beyond routine endoscopy.

Multidisciplinary decision-making

Complex cases and invasive cancers are considered in conjunction with appropriate gastroenterology, surgical, oncology and pathology expertise.

Clear communication and follow-up

Findings, pathology and recommendations are communicated clearly to patients and their referring doctors, with surveillance or further treatment arranged where required.

Patient journey

From referral to follow-up.

Every pathway is individual, but most patients follow three simple stages.

01 — ASSESSMENT

Review & planning

The referral, previous endoscopy, imaging and pathology are reviewed to determine the appropriate next step.

02 — TREATMENT

Specialist procedure

Where appropriate, treatment is performed in an accredited hospital or day-hospital setting.

03 — FOLLOW-UP

Results & ongoing care

Pathology and findings are reviewed and a surveillance or further-treatment plan is communicated.

For referring doctors

Refer a patient.

Referrals are welcomed from General Practitioners, gastroenterologists, surgeons and other specialists. GPs are welcome to refer patients for both general gastroenterology and specialist endoscopic assessment. A referral outlining the clinical question, with relevant pathology, imaging and previous endoscopy reports where available, helps us arrange the most appropriate care.

Common questions

Before you book.

Can I be referred specifically for ESD or EMR?

Yes. Patients with large or complex gastrointestinal lesions can be referred for an advanced endoscopic opinion. The most appropriate treatment is determined after review of the clinical history, endoscopic findings and pathology where available.

Is advanced endoscopy an alternative to surgery?

For selected early gastrointestinal neoplasia, endoscopic resection may provide definitive treatment while preserving the involved organ. Suitability depends on the depth and nature of the lesion, the risk of lymph-node or metastatic disease, technical considerations and the available alternatives.

What happens after an ESD or EMR?

The resection specimen is reviewed by pathology and the results are used to determine whether endoscopic surveillance, further endoscopic treatment or another treatment approach is appropriate. Recommendations are communicated to the patient and referring doctor.

Where are procedures performed?

Procedures are performed at selected accredited private hospitals and day hospitals in Adelaide. The appropriate location depends on the procedure and the patient's individual requirements.

Advanced endoscopy

Specialist expertise. Thoughtful care.

Advanced endoscopy combines technical expertise with careful patient selection, clear communication and close collaboration with referring doctors.
