A study of Fuji Intelligent Chromo Endoscopy in the diagnosis of colonrectal neoplasia

Objective To investgate the value of Fuji Intelligent Chromo Endoscopy(FICE)for the diagnosis of colonrectal polympus.Methods 197 patients who had colon polypoid lesion examined with ordinary colonoscopy from March 2009 to January 2010 were enrolled in this study.The patients were examined with magnifying conventional colonoscopy,magnifying FICE technique and magnifying chromoendoscopy technique,the pit pattern and blood capillary form.The endoscopic diagnosis was made,and compared with pathologic diagnosis.Results 359 neoplasms were detected in the197 patients,among those 91.2% were detected with magnifying conventional endoscopy,97.8% were detected with FICE technique ,there was significant difference between the two methods.the structure and form of mucosal blood capillary saw mere clearly in FICE than that in chromoendoscopy technique,(P ＜ 0.01),there was no significant difference between the two methods for showing the pit pattern.The coincident rate of FICE for the diagnosis of tumor and non-tumor polynpus was 90.3%,which was significant higher than that of chromoendoscopy 82.5% (P ＜ 0.01).Conclusion Magnifying FICE endoscopy could show mucosal microstructure and blood capillary form.It hav the superiority of high coincident rate in distinguishing neoplastic from non-neoplastic colorectal polympus compared with conventional magnifying colonoscopy and magnifying chromoendoscopy.The detected rate of early carcinoma of colon is dramatically increased with FICE.FICE could be easily operated,and hare satisfactory clinical practical value.
