A study of Fuji Intelligent Chromo Endoscopy and ultrasonic endoscope in the diagnosis of precancerous lesion and early carcinoma of colon

【Objective】 To investgate the value of Fuji Intelligent Chromo Endoscopy(FICE) and ultrasonic endoscope for the diagnosis of colonrectal neoplasia.【Methods】 667 patients were examined with ordinary colonoscopy.94 patients with colon neoplasm or polypoid lesion were enrolled in this study.The patients were examined with magnifying conventional colonoscopy,magnifying FICE technique and ultrasonic endoscope,the pit pattern and blood capillary form of the lesion were examined,the infiltration depth of the lesion were examined by ultrasonic endoscope.The endoscopic diagnosis was made,and compared with pathologic diagnosis.【Results】 172 neoplasms were detected with FICE technique in the 94 patients,among those 17 lesion were undetected with magnifying conventional endoscopy,The coincident rate of FICE for the diagnosis of tumor and non-tumor lesions were 93.8%、91.3%,which were significant higher than that of chromoendoscopy 88.4%、75.6%(P0.05).【Conclusion】 Magnifying FICE endoscopy had the superiority of high coincident rate in distinguishing neoplastic from non-neoplastic colorectal lesions compared with conventional magnifying colonoscopy.It conduces to find precancerous lesion,and diagnoses preliminary the infiltration depth of the colon lesion.
