Last month, I had to undergo a colonoscopy and an endoscopy. For those of you who don’t know what these are, a colonoscopy is a procedure where a doctor (usually a Gastroenterologist) inserts a long, thin tube inside the patient’s rectum. The tube has a tiny video camera which is connected to a screen where it shows the live images, and this is used to look at the colon (aka large intestine) for any abnormalities. An endoscopy is pretty much the same thing, but this time the tube is inserted down the patient’s throat to look at his or her digestive tract.
