What is Colonoscopy?

Colonoscopy is a procedure used to examine the lining of the colon and rectum. In Singapore, where colorectal cancer is a common cancer among both men and women, colonoscopy plays a pivotal role in early detection and prevention.

In this procedure, a thin, flexible tube equipped with a camera and light source, called a colonoscope, is inserted through the rectum and guided through the entire length of the colon. This allows the doctor to visualize the colon's lining and identify any abnormalities, such as polyps or signs of inflammation.

Why is Colonoscopy Performed?

Early Detection of Colorectal Cancer: Singapore's high incidence of colorectal cancer underscores the importance of regular screening. Colonoscopy can detect precancerous growths known as polyps, which can be removed before they become cancerous. Early detection is crucial for improving treatment outcomes and increasing survival rates.

Diagnostic Tool for Gastrointestinal Issues: Beyond cancer screening, colonoscopy helps diagnose various gastrointestinal conditions such as inflammatory bowel disease (IBD), Crohn's disease, and ulcerative colitis. It enables doctors to identify the cause of symptoms such as abdominal pain, changes in bowel habits, rectal bleeding, or unexplained weight loss.

How is Colonoscopy Performed?

Preparation: Bowel preparation is crucial for a successful colonoscopy. Patients in Singapore are typically given detailed instructions on dietary restrictions and laxative use to ensure their bowels are adequately cleansed. This may involve consuming a clear liquid diet and taking laxatives to empty the colon completely. Adequate bowel preparation is essential for optimal visualization of the colon and accurate detection of abnormalities.

During the Procedure: Patients are sedated to minimize discomfort during the procedure. The colonoscope is inserted gently through the rectum and advanced slowly through the colon. The camera on the tip of the colonoscope transmits high-definition images to a monitor, allowing the doctor to examine the colon's lining in real-time. If polyps or suspicious areas are detected, they can be removed or biopsied during the procedure for further analysis.
