Flexible sigmoidoscopy is a procedure used to examine the rectum and sigmoid colon using a thin, flexible tube with a camera. It is commonly used to investigate lower gastrointestinal symptoms such as rectal bleeding or altered bowel habits.
The procedure is typically performed without sedation and takes only a few minutes. Air or carbon dioxide is used to gently expand the bowel for better visibility. Biopsies can be taken, and abnormalities such as polyps or inflammation can be identified.
It is generally safe, with rare risks including bleeding or perforation. Mild discomfort or bloating may occur.
Preparation usually involves the use of enemas or a limited bowel prep to ensure the lower colon is clear.
