Our Services Endoscopic Diagnosis and Treatment Colonoscopy

Colonoscopy is an investigatory procedure which allows the doctor to look at the inner lining of the large bowel (colon) by using a long flexible tube (the size of your index finger) with a light source and a tiny video camera at the end. The tube is passed carefully through the anus and the doctor looks inside the colon for pathologies such as inflammation, bleeding, polyps or tumours. Biopsies (small pieces of tissue) may be taken and polyps can be removed with tiny forceps during colonoscopy. Taking biopsies is painless and safe.

Colorectal cancer screening – Do I need colonoscopy?
Colorectal cancer is the second most common cancer in Hong Kong after lung cancer. Because it starts as a polyp that transforms into cancer in 10-15 years, colorectal cancer is preventable when polyps are found and removed at early stages. A Hong Kong colorectal cancer screening study found that 1 in 8 asymptomatic adults older than 50 had adenomatous polyps in their colons. Their polyps may turn into cancer if not removed.

As most polyps are asymptomatic, those above the age of 45 should consider undergoing colonoscopy regularly to screen for colorectal cancer as a preventive measure. High risk individuals such as those with a family history of colorectal cancer may even consider an earlier test.

Endoscopy Centre
The Centre is managed by a team of dedicated and experienced endoscopists. It is equipped with state-of-the-art endoscopic imaging systems and the aim is to provide high quality services in the diagnosis and treatment of diseases of the gastrointestinal tract, biliary and pancreatic system as well as the respiratory system. If necessary, during the procedure, the patient can be sedated with the help of our experienced anaesthesiologists to minimize any discomfort he/she might encounter during the procedure.

Our specialist will tell you right after the procedure what is seen in your colon. If biopsies are taken, it will take 2 to 3 working days to complete the report. Your specialist or attending doctor will contact you for subsequent follow-up and treatment.
