What Is A Colonoscopy, And Why Is It Performed?


A colonoscopy is a key part of colorectal cancer (colonoscopy) screening in Singapore.

It is a procedure where a colonoscope, which is a 1.6m flexible tube with a video camera at the end, is inserted into your colon or rectum wall. It allows your doctor to examine the inside of your colon and its lining for signs of bowel-related conditions, such as colon polyps which can lead to colorectal cancer.

A colonoscopy in Singapore lasts for about 30 minutes to an hour each time, and is a painless procedure conducted under general anaesthesia. Doctors can also utilise the colonoscope to generate images of the colon and rectal wall and identify and remove colon polyps, making a colonoscopy a diagnostic and therapeutic procedure.

As colorectal cancer is the most common cancer in Singapore amongst men, a colonoscopy is a key part of regular colorectal cancer screening tests in Singapore, particularly for residents over the age of 50 (who are also high-risk individuals).

What Is Colorectal Cancer?

Colorectal cancer is a serious malignant disease that affects the colon. Colorectal cancer begins from polyps – a type of growth that’s precancerous or potentially cancerous forming along the inside of the colon. 

They often show no symptoms in the early stages until the cancer has advanced to a more severe stage of metastasis, which will prove far more difficult for a patient’s full recovery. 

Unlike other cancers, colorectal cancer has a far higher rate of full recovery if detected and treated early, with up to 90% of early-detection cases making a full recovery. 

This highlights the importance of colonoscopy in colorectal cancer screening in Singapore to facilitate effective treatment.


Why Do Patients Hesitate To Go For A Colonoscopy In Singapore?

Most people know about colonoscopies in Singapore. However, the two main reasons for avoiding a colonoscopy are fear and misinformation. Many patients either have bad experiences or have heard of bad experiences from their friends or relatives about colonoscopy.

They are told to go on a restrictive diet several days before and to consume only liquids the day before the colonoscopy. They are made to drink 4 litres of bowel preparation the night before the colonoscopy and spend the entire night purging in the toilet.

They come to the hospital early in the morning (dehydrated and sleepy) and they are sedated for a colonoscopy. When the procedure is done, they wake up sleepy and drowsy and are sent home.

The results of the colonoscopy are only known a few weeks after they see the doctor in the clinic. It is no wonder why patients avoid such an essential investigation.

Years later, when they are due for another colonoscopy, most patients will avoid doing it. This is not ideal as it is not in your best interest to delay such an essential investigation.

However, a good specialist will advise that good bowel preparation is important. The state of your stool sample should be watery and free from any solid particles. Contact us to find out more about procedures and preparation for colonoscopy screening in Singapore.

Dr QM Leong will personally review you in the evening after the sedation wears off and explain the colonoscopy findings before you are discharged. Hence, you will undergo the consultation, bowel preparation, colonoscopy screening and results of the procedure all on the same day.
