A colonoscopy is an essential medical procedure for several reasons.


The purpose of a colonoscopy is to look inside your colon using a flexible endoscope (see Figure 1), for polyps, cancers, ulcers, and other conditions.

  • Cancer Prevention: It helps identify and remove colon polyps before they can develop into colon cancer.
  • Diagnosis: It can diagnose bowel and rectal cancer and other gastrointestinal disorders like ulcerative colitis, Crohn's disease, and colitis.
  • Symptom Investigation: It explores possible causes of abdominal pain, rectal bleeding, chronic diarrhea, and other intestinal problems.

By allowing direct visualisation of the entire colon and rectum, a colonoscopy enables doctors to detect abnormalities that may not be visible through other diagnostic tests. It's a proactive step in maintaining gastrointestinal health and is recommended for individuals aged 50 or older as part of regular cancer screening protocols.

It is important to note that a Colonoscopy is the only complete diagnosis tool for Colorectal (Bowel and Rectal) cancers. Colorectal cancer is the second most common non-cutaneous malignancy in Australia.

  • 15, 367 cases in 2023 (8133 men and 7234 women) and second only to lung cancer in terms of cancer mortality.
  • In 2021 there were 5,350 deaths attributed to colorectal cancer. (Source: Australian Institute of Health and Welfare)
  • Early detection is crucial, with 90% of cases successfully treatable.

Symptoms & Conditions:

There may be several reasons why your GP has recommended you need to have a Colonoscopy or repeat Colonoscopy:

It's crucial to recognise that many individuals may not be aware of their family history of bowel or rectal cancer. Therefore, taking any symptoms seriously is vital.

Furthermore, data from Australia and around the world indicate that colorectal cancers are being diagnosed at younger ages more frequently. For instance, the Australian diagnosed rate of Colorectal cancers in the 20-39 age group has risen from 4.4 per 100,000 people in 2001 to 10.3 per 100,000 people in 2021 (AIHW - Cancer in Australia)

Before the Procedure

During your appointment with Dr. Golani, he will review your symptoms and family history of medical conditions. He will also outline the colonoscopy procedure and discuss the necessary preparations, which include a bowel-preparation regimen to be followed one day before the colonoscopy. Bowel preparation is essential as poor preparation can make it difficult to detect polyps and bowel cancer. This appointment will also cover any adjustments to your current medications.

Additionally, you'll have the opportunity to select the hospital for your procedure and potentially set the date for your colonoscopy.

The best surgical hospitals in Sydney are available for your surgery:

Please note that you will need to take two days off work: one day for the pre-procedure preparations and another for the day of the colonoscopy itself.

During the Procedure

The procedure will approximately take 45mins to 90 mins to complete, as the scope needs to pass through your colon (large bowel) to ensure the examination is thoroughly completed.

Just before the procedure starts, you will receive a sedative to make you sleepy. This sedative will help you avoid discomfort from the procedure. Most people do not remember having the procedure. Dr Golani will begin the colonoscopy with a rectal examination. Then he will then insert the scope into the anus and as it's advanced, and he will inflate the bowel with a stream of carbon dioxide to allow better visualisation of the surface.

The endoscope is a thin, flexible tube that has a light and a camera at the tip. Images from the camera go to a TV monitor in the procedure room, allowing Dr Golani to see the inside of your colon on screen.

Dr Golani will look for polyps, inflammation, cancer, or other abnormalities throughout your colon. He will also remove any polyps that are found.

This is usually done by passing a wire loop through the colonoscope to cut the polyp from the wall of the colon with an electric current. The goal is to avoid advanced cancers at a later stage thus thep olyp should be removed in one piece.

After the Procedure

During the colonoscopies if required biopsies and photographs were taken to help make a diagnosis. After the procedure, you will need to recover for about 30-60 minutes to let the sedative wear off. You may feel some gas during your recovery caused by the gas used to inflate your colon. Most hospitals will require someone to help you get home afterwards.

There is no recovery period after the procedure, and you are able to go back to your usual activities (work) the next day.

You will need to book a post-op consultation 4 weeks after the colonoscopy. This will discuss your findings.

Dr Golani will also help you treat the diagnosis after the colonoscopy.
