MINIMALLY INVASIVE CARE

Colonoscopy

A minimally invasive endoscopic examination of the colon, rectum and caecum to investigate large intestinal disease.

What is Colonoscopy?

Colonoscopy is a minimally invasive endoscopic procedure used to examine the lower gastrointestinal tract including the colon, rectum, caecum and anus. Using a flexible endoscope, the team can directly visualise the inner lining (mucosa) of the large intestine and obtain biopsy samples for accurate diagnosis.

Because of the relatively simple structure of the lower GI tract, it is one of the most effective tools for investigating large intestinal disease. It is performed under general anaesthesia following fasting and bowel preparation, is well tolerated and carries a low risk of complications.

Key Benefits

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

1

No open surgery

Full visualisation of the mucosa without abdominal surgery.

2

Accurate biopsies

Multiple targeted samples support a definitive diagnosis.

3

Lower risk

Lower risk and faster recovery than surgical exploration.

In Detail

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

Why it is important

Diseases affecting the large intestine often cause persistent or recurrent clinical signs that may be difficult to diagnose using non-invasive methods alone.

  • Direct visualisation of the intestinal lining
  • Accurate assessment of inflammation or disease
  • Targeted biopsy sampling
  • The ability to reach a definitive diagnosis in many cases

Understanding the large intestine

The large intestine in dogs and cats consists of the caecum, the colon (ascending, transverse and descending), and the rectum and anus.

An important anatomical landmark is the ileocaecocolic junction, where the small intestine connects to the large intestine. This area is often assessed during colonoscopy and plays a key role in diagnostic evaluation.

Diagnostic capabilities

  • Examine the entire large intestinal lining
  • Identify abnormalities such as inflammation, ulcers or masses
  • Take multiple biopsy samples for laboratory analysis
  • Assess disease severity and distribution

Procedure and preparation

Colonoscopy is performed under general anaesthesia. Preparation is important and typically includes fasting and bowel preparation to clear intestinal contents. The procedure is well tolerated and carries a low risk of complications.

  • A flexible endoscope is inserted into the rectum
  • The colon is carefully examined
  • Biopsy samples are collected if needed

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.
