About Us

Julian Ong Endoscopy & Surgery (Pte Ltd) provides a comprehensive range of services for the management of all colorectal conditions. The services include endoscopy, perianal surgery and minimally invasive surgery for the colon and rectum, for both benign and malignant conditions.

As conditions affecting the colon, rectum and anus are very common, you need not have to feel awkward about having a endoscopy and a proper medical check. In fact, it is the best way to determine whether you need to seek any treatment quickly.

Dr Julian Ong’s vast experience lies in surgery for perianal conditions, as well as laparoscopic ("key-hole") and open techniques of colorectal surgery. In addition, his sub-specialty expertise is in advanced minimally invasive surgical procedures, such as single-port, and robotic assisted surgery.

General Practitioners and Family Physicians may arrange for Dr Ong to perform Upper and Lower Gastrointestinal Endoscopy for their patients.
