[ Summary ] |
Colonoscopy has gained wide-spread acceptance as a useful tool for the diagnosis and management of colon disease, however, techniques for its use are not easy and are hazardous to patients. To avoid abdominal pain, due to making a large, non-physical loop with the scope, X-ray guided control is useful. However, we must consider the danger of X-rays to the patient, the colonoscopist, the scope and so on. We have established a new method, using magnetic fields to determine the loop of the colonoscope without the help of X-ray; the Endoscopic Contour Detection Device (Colonavi). Using this new device, we can see the loop of the scope clearly, and resolve dangerous conditions. By using this device, danger to patient during colonoscopy can be decreased. Moreover, good step-by-step educational training to master insertion techniques for colonoscopy may be established. |
