A comparative study on a new transnasal gastroscopy and routine gastroscopy
2013
Objective To investigate the clinical value of new transnasal Fujifilm EG-530-NW electronic gastroscope. Methods A total of 295 patients who underwent gastroscopy were randomly divided into 2 groups to receive examination by routine endoscope ( n = 172 ) or Fujifilm EG-530-NW transnasal endo- scope (n = 123). The fluctuation of heart rate, blood pressure and compliance during the examination were recorded and compared between the two groups. Results The new Fujifilm EG-530-NW could obtain clear images with same quality of routine gastroscope. The heart rate change and visual analog pain score in pa- tients from EG-530-NW gastroscope group were significantly lower than those of routine gastroscope group ( P 〈 0.05 ). No significant difference in blood pressure fluctuation was observed between the two groups. In patients older than 50 years, the fluctuations of heart rate and blood pressure in EG-530-NW group were significantly less than those of routine gastroscope group. Conclusion Fujifilm EG-530-NW gastroscope can get high quality image with less influence on heart rate and blood pressure fluctuation, which is more signifi- cant in older patients.
