Endoscopes, Gastrointestinal Tract, Lower Tract, Video/Ultrasound
Definition : Lower-gastrointestinal-tract endoscopes designed to access, examine, diagnose, and/or treat the lower gastrointestinal tract (rectum and colon) using video cameras and ultrasonic probes. These endoscopes usually consist of an outer (plastic or metal) sheath, a lighting system (e.g., fiber optics), a video camera at the distal tip, an ultrasonic probe with appropriate transducers, and a working channel through which catheters and operative devices are introduced. Lower-tract video/ultrasonic endoscopes are usually flexible devices intended for visual evaluation of the colon and assessment of lesions (e.g., polyps) using ultrasound scanning that may include Doppler techniques.
