檢查過程     
Examination Process

在注射靜脈鎮靜或麻醉科醫生監控下麻醉，以確保病人在熟睡情況下進行檢查，是不會感覺不適。
醫生會替病人肛門部位塗上潤滑劑。隨後將一支柔軟，直徑約為 1.5 厘米之內視鏡由病人肛門放進體內進行檢查。檢查過程中如發現瘜肉，醫生一般會即時切除瘜肉，並將組織樣本作化驗。大腸內窺鏡檢查程序由準備至完成需時大概30分鐘。檢查後必須在床上休息至少一小時，待鎮靜劑藥物減退後才可下床離開。

The examination usually takes 15 – 20 minutes, depending on the area being examined. To get a high-quality picture, the breast being examined must be flattened or compressed. The technologist may ask the patient to change position, so your breast is compressed from side to side before the next x-ray is taken.
