MINIMALLY INVASIVE CARE

Gastroscopy

A minimally invasive endoscopic examination of the oesophagus, stomach and upper small intestine for accurate diagnosis of gastrointestinal disease.

What is Gastroscopy?

Gastroscopy (upper gastrointestinal endoscopy) uses a flexible camera passed through the mouth to examine the oesophagus, stomach and upper small intestine (duodenum) in high detail. It is one of the most valuable diagnostic tools in veterinary medicine, particularly when routine tests are unclear or symptoms persist.

A major strength is its ability to detect mucosal disease that may not appear on X-rays or ultrasound. Targeted biopsies can be taken safely with minimal, controlled bleeding, allowing a definitive diagnosis of inflammatory, infectious and neoplastic conditions. It is performed under general anaesthesia and most pets recover quickly.

Key Benefits

Why this minimally invasive approach is the right choice for your pet.

1

Minimally invasive

No large incisions, with very low complication and mortality rates.

2

Accurate biopsies

High-quality tissue samples from mucosal surfaces that imaging can miss.

3

Faster recovery

Most pets recover quickly after the procedure.

In Detail

A closer look at how this procedure works and what it can diagnose and treat.

Why it is important

Gastrointestinal diseases can be complex and difficult to diagnose using external tests alone. Gastroscopy provides a direct and highly accurate assessment of the digestive tract.

  • Routine tests do not provide a clear diagnosis
  • Symptoms persist despite treatment
  • A more precise evaluation of the stomach or intestines is required

Diagnostic accuracy and biopsy

A major strength of gastroscopy is its ability to detect mucosal disease, which may not be visible on imaging such as X-rays or ultrasound.

  • Small tissue samples (biopsies) can be taken safely
  • Bleeding is minimal and controlled
  • Samples are more precise than blind or indirect methods
  • Allows a definitive diagnosis of inflammatory, infectious and neoplastic conditions

Preparation before gastroscopy

Gastroscopy is typically performed after initial, non-invasive investigations to ensure it is necessary and safe.

  • Full clinical history and physical examination
  • Blood tests to assess overall health
  • Faecal analysis (especially in diarrhoea cases)
  • Abdominal imaging (X-rays and ultrasound)

How the procedure works

Gastroscopy is performed under general anaesthesia. The entire process is atraumatic and well tolerated by most patients.

  • A flexible endoscope is inserted through the mouth
  • It is advanced through the oesophagus into the stomach and duodenum
  • The internal lining is examined in detail
  • Biopsies or minor treatments are performed if required

Limitations

While highly effective, gastroscopy has some limitations, so it is often combined with imaging techniques such as ultrasound or radiography for a complete evaluation.

  • It only evaluates the inner lining (mucosa) of the GI tract
  • Some areas beyond reach cannot be assessed
  • It may not detect disease outside the gastrointestinal wall (extramural disease)

What to Expect

1

Initial Investigations

We review history and run initial, non-invasive tests and imaging to confirm the procedure is appropriate and safe.

2

General Anaesthesia

Your pet is placed under general anaesthesia and carefully monitored to ensure comfort and safety.

3

Endoscopic Examination

The endoscope is gently introduced and the relevant structures are examined in high detail.

4

Sampling & Treatment

Biopsies or treatment are carried out during the same procedure where needed, and findings are discussed with you.

Frequently Asked Questions

Yes. The procedure is performed under general anaesthesia to ensure your pet’s comfort, safety and a thorough, pain-free examination. It is minimally invasive and well tolerated when performed by experienced clinicians.
As a minimally invasive technique, it avoids the large incisions of traditional surgery, which means less tissue trauma, lower complication rates and a faster recovery. Your specialist will provide aftercare guidance based on the findings.
