Why Early Colorectal Screening Matters

Colorectal cancer is one of the most common cancers affecting both men and women in Singapore, yet many cases can be prevented through regular screening and the removal of precancerous polyps.

Colorectal cancer and colon polyps often develop without noticeable symptoms in their early stages. A colonoscopy allows doctors to detect and remove these polyps, helping to reduce the risk of colorectal cancer.

In Singapore, routine colorectal cancer screening is generally recommended from age 50 for individuals at average risk. However, it’s worth noting that colorectal cancer can also affect younger adults. Screening may involve an annual Faecal Immunochemical Test (FIT) or a colonoscopy at intervals recommended by your doctor.

Individuals with a family history of colorectal cancer, previous polyps or other risk factors may require earlier or more frequent screening. Speak to your doctor about the screening approach most suitable for you.

Bowel and Digestive Symptoms That Require Medical Attention

Experiencing changes in your bowel habits or digestive health? While occasional discomfort may not be a cause for concern, persistent or recurring symptoms should not be overlooked, as they may indicate an underlying condition that requires medical attention.

Dr Leong Quor Meng is a general and colorectal surgeon in Singapore, and the surgeon behind Advanced Colorectal And General Surgery, a one-stop treatment centre for colorectal diseases and conditions at Mt. Alvernia Hospital. He graduated from the University of London in 2000 and obtained his membership to the Royal College of Surgeons of Edinburgh in 2003, the same year he started working at Tan Tock Seng Hospital. He began his Advanced Specialist Training in 2005 and passed his fellowship exams in 2008. In 2010, he received the MOH HMDP scholarship to train under Prof Kim Seon Hahn at Korea University for laparoscopic and robotic colorectal surgery.

Dr Leong performs Single Incision Laparoscopic Surgery (SILS), a minimally invasive technique associated with quicker recovery and less visible scarring. He also trains basic and advanced specialist trainees in laparoscopic surgery and proctors consultant surgeons in complex colorectal cases. He has performed over 10,000 endoscopic procedures, covering diagnostic and therapeutic scopes for both planned and emergency conditions, including direct access colonoscopies and oesophago-gastro-duodenoscopy. His clinical focus covers colorectal cancer, haemorrhoids, gallstones, gastric conditions, hernias, and piles, and he works between minimally invasive techniques and open surgery depending on what the condition calls for.

At Advanced Colorectal And General Surgery, colorectal surgery, colonoscopy screening, and general surgery are brought together under one roof. Patients are assessed by Dr Leong, supported by diagnostic endoscopy and screening, and guided through their treatment options in a single, coordinated care setting. Where suitable, consultation and colonoscopy can take place on the same day, so patients don’t need a separate visit just to get screened, making it easier to catch colorectal conditions early before they progress. Care continues past the procedure itself, with our nursing staff working alongside Dr Leong to support patients through treatment and recovery.

What Is Colorectal Surgery?

Colorectal surgery refers to a group of surgical procedures for conditions affecting the colon, rectum, and anus. These may include cancerous and non-cancerous conditions such as colorectal cancer, inflammatory bowel disease, diverticulitis, rectal prolapse, anal fistulas, haemorrhoids, and complications linked to bowel obstruction or injury. The aim is usually threefold: to remove or repair the affected tissue, to restore normal bowel function as far as possible, and to reduce the risk of complications later on.

Many of these procedures can be carried out using minimally invasive, or keyhole, techniques. Instead of one large cut, the surgeon works through a few small openings. While open surgery remains a suitable choice in some cases, and your colorectal surgeon will talk you through which approach fits your situation.

Common Procedures For Colorectal Surgery In Singapore

The scope of colorectal surgeries in Singapore ranges from minimally invasive laparoscopic procedures to more extensive operations, depending on the severity and nature of the condition being treated.

Some of the procedures a colorectal surgeon may perform include:

Colectomy: This involves the surgical removal of part or the entire colon, often necessary for treating or preventing diseases affecting the colon.
Colostomy: Creates an opening in the abdominal wall for stool to pass into a bag, used in situations where the lower bowel requires rest or removal.
Haemorrhoidectomy: The surgical removal of haemorrhoids, which are swollen veins in the lower part of the anus and rectum.
Polypectomy: Removal of polyps from the colon’s inner lining. Polyps are usually benign but can sometimes develop into cancer.
Rectal Prolapse Surgery: This surgery corrects a rectal prolapse, where the rectum slips outside of the anus.
Anal Fistula Surgery: A procedure to repair an anal fistula, an abnormal tunnel between the anal canal and the perianal skin.
