'''Sigmoidoscopy''' ("sigma", the Greek term for letter "[[Sigma|s/ς]]" + "eidos" + "scopy": namely, to look inside an "s"/"ς"-like object) is the [[invasiveness of surgical procedures#Minimally invasive procedure|minimally invasive]] [[medicine|medical]] examination of the large [[intestine]] from the [[rectum]] through to the nearest part of the [[colon (anatomy)|colon]], the [[sigmoid colon]]. There are two types of sigmoidoscopy: '''flexible sigmoidoscopy''', which uses a flexible [[endoscopy|endoscope]], and '''rigid sigmoidoscopy''', which uses a rigid device. Flexible sigmoidoscopy is generally the preferred procedure. A sigmoidoscopy is similar to, but not the same as, a [[colonoscopy]]. A sigmoidoscopy only examines up to the [[sigmoid colon|sigmoid]], the most distal part of the colon, while colonoscopy examines the whole large bowel.
