Newly devised upper gastrointestinal endoscopes, GIF-XQ30 and GIF-P30, were evaluated clinically concerning to insertion, observation and biopsy channel comparing with GIF-XQ20 and GIF-P20.
Endoscopists who examined the same 55 patients with GIF-XQ30 and GIF-XQ20, or GIF-P30 and GIF-P20 answered a questionnaire. It revealed that by using GIF-XQ30 or GIF-P30 examiners could insert endoscopes more easily to the duodenal bulb, observe more widely especially at the down-observation or at the inverted observation, and insert biopsy forceps more easily through the channel even at the inverted observation than by using GIF-XQ20 or GIF-P20.
These results indicate that GIF-XQ30 and GIF-P30 are more useful in the endoscopic diagnosis than the previous endoscopes.
