Our colon is not a straight line, so when the surgeon performs a colonoscopy, he or she does
\nnot simply push the tube-like endoscope through the colon. After the endoscope passes
\nthrough the rectum, it reaches the curvy sigmoid colon, and the two right-angled turns of
\nsplenic flexure and hepatic flexure are waiting ahead. It is relatively easy to pass through the
\nfirst turn, but if the endoscope is being pushed forward at the second or third turn, the
\ncurvature at the first might become too much for the human intestine to hold. In some
\ncases, the endoscope just cannot proceed forward, and in some extreme cases the bend of
\nthe endoscope might even tear apart tissues of the intestinal wall.
\nFor a smooth colonoscopy, it is important to keep the endoscope as straight as possible.
\nAfter the endoscope has passed through a turn of the colon, it is necessary to slightly pull it
\nbackward to reduce the curvature. At the same time, the doctor would remove all gases
\ninside the colon so that the intestinal wall would tightly enwrap the endoscope. When the
\nendoscope reaches the end of the colon, the doctor can slowly pull it backward to examine
\nthe mucosa of the intestinal wall. Keeping the endoscope straight also help avoid the
\ncamera at the head moving too fast at the bends, preventing a careful examinations of the
\nintestinal wall at those turns.
\nIn colonoscopy, precision in the movement of endoscope is the key \u2013 every millimetre
