A flexible sigmoidoscopy is a procedure that allows your gastroenterologist (GI specialist) to examine the lower part of your large bowel (the colon). This test uses a thin, flexible tube called an endoscope, which is about the thickness of your index finger.
During a flexible sigmoidoscopy, the endoscope is gently inserted into your bottom (rectum) and the lower part of the colon. Your specialist will be looking at the images on a video monitor. A flexible sigmoidoscopy test is a minimally invasive day case procedure. So, you should be able to return home the same day.
Before your sigmoidoscopy test, you will meet with your gastroenterology consultant. They will explain what the test involves, how to prepare for it, and will answer any questions you may have.
When you discuss the procedure, tell your specialist about any medications or supplements you take, as well as medical conditions that you may have, such as heart or lung disease. You may need to stop taking some of these medicines before the procedure.
