Endoscopy & Colonoscopy

Endoscopy and colonoscopy are common procedures used to investigate gastrointestinal (GI) symptoms, diagnose conditions early, and guide the right treatment plan. Thomas performs diagnostic and therapeutic endoscopy for patients across the Hutt Valley, Wairarapa, and Kāpiti Coast, using up-to-date techniques and equipment.

These procedures help identify the cause of symptoms such as abdominal pain, changes in bowel habits, bleeding, reflux, or unexplained digestive discomfort. Many patients find that endoscopy provides clarity and confidence about what is happening inside the body — and what to do next.

What endoscopy involves

Endoscopy uses a thin, flexible camera to examine the inside of the upper or lower GI tract. This allows Thomas to diagnose conditions such as inflammation, ulcers, polyps, diverticular disease, and early signs of cancer.

There are two main types:

  • Gastroscopy (upper endoscopy) — examines the oesophagus, stomach, and duodenum

  • Colonoscopy — examines the colon and rectum

Both are usually performed under light sedation to ensure comfort, and most patients go home the same day.

When an endoscopy may be recommended

You may be referred for endoscopy or colonoscopy if you are experiencing:

  • Persistent abdominal pain

  • Ongoing reflux or indigestion

  • Difficulty swallowing

  • Unexplained weight loss

  • Changes in bowel habits

  • Rectal bleeding

  • Anaemia

  • A family history of bowel cancer

  • Ongoing bloating or digestive issues

Endoscopy helps determine whether symptoms are caused by inflammation, structural problems, infections, polyps, or other underlying conditions.

Benefits of endoscopy

Endoscopy is one of the most effective ways to:

  • Diagnose GI conditions early

  • Detect polyps before they become cancerous

  • Assess inflammation or bleeding

  • Take biopsies for further investigation

  • Remove polyps or treat certain conditions during the procedure

  • Plan the right next steps in your care

It is a key part of modern gastrointestinal investigation and is often the most accurate way to understand the cause of ongoing digestive symptoms.

FAQs

Is the procedure painful?

Endoscopy and colonoscopy are performed under light sedation, so most patients are comfortable and remember very little.

How long does the procedure take?

Most endoscopies take 10–20 minutes. Colonoscopies usually take 20–45 minutes. You’ll remain in recovery until you’re ready to go home.

What preparation is needed?

Colonoscopy requires bowel preparation the day before. Gastroscopy typically requires fasting. Clear instructions will be provided before your appointment.

How soon will I get results?

Thomas will explain the findings on the day. If biopsies are taken, results usually follow within a few days.

Is endoscopy safe?

Yes. Endoscopy is a very safe procedure when performed by trained specialists using modern equipment and techniques.
