About Colorectal Practice
Led by Singapore colorectal surgeons Dr Dennis Koh, Dr Sharon Koh, and Dr Pauleon Tan, we offer comprehensive treatments for piles, colon and colorectal surgery.
The bulk of Colorectal Practice's bookings cover Digestive & Internal Medicine. Because this is a focused healthcare operation, most jobs are scoped over WhatsApp first — photos of the issue, property type, and preferred slot — before a price is quoted.
Colorectal Practice covers all of Singapore, which is useful if you live in a less-central estate or need a provider that can follow a recurring job to different addresses. The business is KakiList-verified, meaning a real person has confirmed the operating details and contact channel. Google reviewers currently give Colorectal Practice a strong average of 5/5 across 212 reviews, which is a reasonable signal of consistency for a healthcare provider.
If you want to gauge whether Colorectal Practice is the right fit for your job, the fastest path is a WhatsApp message with photos of the issue, your postal code, and a rough preferred slot. Most providers on KakiList respond within a few hours during business hours and can quote before scheduling a visit.

I recently had a colonoscopy done by Dr. Leong, and I had a very positive experience. The team was professional, attentive, and took great care of me throughout every step of the process. They explained everything clearly and made sure I felt comfortable and well-informed. The procedure went smoothly, and I truly appreciated that Dr. Leong personally came to see me right after the scope to ensure I wasn’t leaving the hospital with any doubts or concerns. That level of care and reassurance meant a lot. Special thanks to Dr. Leong for his expertise and dedication, and to his assistant, Ms. Sharon, for her kindness and support throughout the entire process. I would highly recommend this clinic to anyone looking for thorough and professional medical care.

Dr Leong is an excellent and experienced doctor. I underwent piles surgery under his care, and from consultation to post-operation follow-ups, he was calm, reassuring, and professional. He explained everything clearly and addressed my worries patiently. Recovery wasn’t easy, but Dr Leong monitored my progress closely and guided me well. I truly appreciate his dedication and would recommend him to anyone dealing with similar conditions. I would also like to commend the clinic staff team, they were friendly, caring, and very responsive. Whenever I had issues or concerns after the surgery, I could WhatsApp them and they replied quickly and promptly, which gave me great reassurance during recovery. Thank you all :)

I recently had a colonoscopy performed by Dr. Leong and I couldn’t be more grateful for the outstanding care I received. The entire procedure was smooth, seamless, and went perfectly, truly a success from start to finish. Dr. Leong was incredibly efficient, professional, and provided excellent advice that put me at ease throughout the process. A huge shoutout to the front desk team as well, they were friendly, organized, and made everything run effortlessly. Special thanks to Suzy for her exceptional service and warm demeanor; she really went above and beyond! Highly recommend this practice to anyone needing gastrointestinal care. Thank you for making a potentially stressful experience so positive and comfortable!

⭐️⭐️⭐️⭐️⭐️ Dr Leong – Advanced Colorectal and General Surgery I had an excellent experience under the care of Dr Leong at Advanced Colorectal and General Surgery. From the first consultation, Dr Leong was calm, thorough, and very clear in his explanations. He took the time to walk me through the procedure and what to expect at each stage, which was extremely reassuring. Nothing felt rushed, and all my questions were answered patiently. Special thanks to his team, who were professional, attentive, and kind throughout the process. They made each visit smooth and comfortable. Overall, the entire experience — from consultation to follow-up — was handled seamlessly. I would highly recommend Dr Leong and his team to anyone looking for a knowledgeable, careful, and trustworthy colorectal surgeon.

I had the privilege of being under the care of Dr Leong and his team (Sharon, Suzie, Manru). Underwent a successful hemorrhoidectomy, colonoscopy, and endoscopy with Dr Leong in December 2025. I am now back to a normal lifestyle that was not possible prior to the operation. It's well known that hemorrhoidectomies are generally painful, but I experienced minimal discomfort. Recovery was smooth and the service, outstanding all round. Aside from surgical excellence, what stands out is Dr Leong's warmth, compassion, and equally matched sense of humour. He puts you at ease. I also very much appreciate the care team's responsiveness and efficiency. They are true professionals in their field. Big thank you to all at Advanced Colorectal!
