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.

Our Areas Of Expertise

We specialise in the diagnosis and treatment of colorectal, digestive and general surgical conditions, offering both non-surgical and surgical treatment options based on individual needs.

Where surgery is necessary and suitable, minimally invasive techniques may be used to reduce postoperative pain, shorten hospital stays and support faster recovery.

For urgent conditions, same-day surgery may be arranged following medical assessment, depending on the patient’s condition and suitability.

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, restore normal bowel function as much as possible and reduce the risk of further complications.

Many colorectal procedures can be performed using minimally invasive (keyhole) techniques, where surgery is carried out through small incisions rather than one large opening. However, open surgery may still be necessary or more appropriate for certain conditions. Your colorectal surgeon will assess your condition and recommend the most suitable surgical approach based on your individual needs.

Procedures Performed by a Colorectal Surgeon

Colorectal surgeons perform a range of diagnostic and therapeutic procedures, from endoscopic examinations and minimally invasive surgery to more extensive operations, depending on the nature and severity of the condition:

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 collection 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.
Colonoscopy: An endoscopic examination of the colon and rectum to detect abnormalities such as polyps, inflammation and colorectal cancer.
Gastroscopy (OGD): An endoscopic examination of the oesophagus, stomach and duodenum to investigate upper digestive conditions.
