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.
