It is said that the colonoscopy procedure is as much dreaded by patients as a root canal. Colonoscope is a snake-like instrument that traverses the large intestine from rectum to caecum. The development of colonoscopes was considered a quantum advance in abdominal surgery. It was developed by Dr Wolff, in association with Dr Shinya and Olympus.Their most significant achievement was developing the technique of polypectomy during colonoscopy. They also developed the protocol of using one doctor instead of two for the procedure. Currently, 1.6 million colonoscopies are being performed annually in the USA.
