Safeguard Your Health with a Colorectal Specialist in Singapore

Choosing the right colorectal specialist in Singapore matters, especially when symptoms are easier to treat when picked up early.

A wide range of Singaporeans develop colorectal concerns at some point, from colorectal cancer to non-cancerous conditions such as haemorrhoids, gallstones, hernias, and diverticular disease. Some conditions may only cause mild discomfort at first, but they can become more serious if left unchecked.

Our colorectal clinic is led by Dr QM Leong, a colorectal doctor whose practice centres on early detection, proper diagnosis, and care that fits your condition.

Why Early Colorectal Screening Matters

Many colorectal cancers and polyps cause no symptoms in their early stages, which is why screening matters: it can pick up any internal changes in the colon before symptoms become obvious.Most colorectal cancers begin as small growths called polyps, and these usually take several years to turn malignant. Removing them during a colonoscopy can help mitigate such risks.

Screening is generally recommended from age 50, using a Faecal Immunochemical Test (FIT) each year or a colonoscopy every five to ten years, depending on risk profile and medical advice. And screening is not only for patients with symptoms. It can also support preventive care for those with a family history, previous polyps, or other risk factors that may require closer medical review.

Bowel and Digestive Symptoms That May Require Medical Review

Some colorectal and digestive symptoms may be caused by common conditions such as haemorrhoids, constipation, fissures, indigestion, or inflammation. However, persistent or recurring symptoms should be assessed by a colorectal doctor for a proper diagnosis.

The signs below do not confirm a serious condition on their own, but if any of them last more than a couple of weeks or keep returning, speak with a colorectal doctor for a thorough assessment.

About Dr QM Leong: Colorectal & Hernia Surgeon In Singapore

Dr QM Leong is a general and colorectal surgeon in Singapore who graduated from the University of London in 2000. He obtained his membership to the Royal College of Surgeons of Edinburgh in 2003 and started working at Tan Tock Seng Hospital in the same year. He started his Advanced Specialist Training in 2005, passed his fellowship exams in 2008, and received the MOH HMDP scholarship to train under Prof Kim Seon Hahn at Korea University for Laparoscopic and Robotic colorectal surgery in 2010.

Dr Leong performs Single Incision Laparoscopic Surgery (SILS), a minimally invasive technique that is associated with potentially quicker recovery, and reduced, less visible scarring. He also routinely trains basic and advanced specialist trainees in laparoscopic surgery and proctors consultant surgeons in complex colorectal cases.

Beyond laparoscopic work, he carries out a range of minimally invasive general surgery procedures and has performed over 10,000 endoscopic procedures, covering diagnostic and therapeutic scopes for both planned and emergency conditions. As a colon specialist in Singapore, he performs direct access colonoscopies and oesophago-gastro-duodenoscopy, and aims to complete the procedure on the same day where this is suitable for the patient.

His clinical focus covers colorectal cancer, haemorrhoids, gallstones, gastric conditions, hernias, and piles, among others. Throughout, Dr Leong works around early detection, early intervention, and preventive care, drawing on both minimally invasive techniques and open surgery so the approach fits the condition being treated.

Advanced Colorectal And General Surgery, located at Mt. Alvernia Hospital, is a one-stop treatment centre for colorectal diseases and conditions. The clinic brings colorectal surgery, colonoscopy screening, and general surgery together in one place, so that consultation, investigation, and treatment can be coordinated within a single care setting.

Our focus is digestive health as a whole. Patients are assessed by a colorectal surgeon, supported by diagnostic endoscopy and screening, and then guided through the options relevant to their condition, from minimally invasive surgery to open surgery where that is the appropriate choice.

A central part of what the clinic offers is Same Day Colonoscopy. Where it is suitable, your consultation and colonoscopy can take place on the same day. This encourages patients to seek proper screening and detect colorectal conditions before they increase in severity.

Care does not end at the procedure. Our professional nursing staff are committed to helping our colorectal surgeon and colon specialist provide quality treatment for every patient.

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.
