Abstract:
ObjectiveTo evaluate magnifying endoscopy combined with flexible spectral imaging color enhancement(FICE)for diagnosis of early gastric cancer.MethodsThe suspicious small depressive lesions(SDL) was further studied with magnifying endoscopy or magnifying endoscopy combined with FICE from April 2009 to March 2011 in our hospital.The endoscopic diagnostic criteria of early gastric cancer was made according to the structure of the pit,the microvascular and the demarcation line.ResultsIn 74 SDL,17 were pathologically diagnosed as cancer,and 56 were noncancer.The sensitivity,specificity and accuracy of magnifying endoscopy were 41.18％,94.74％and 82.43％,respectively,which were 86.67％,96.49％ and 91.89％,respectively for magnifying endoscopy combined with FICE.The diagnostic sensitivity of magnifying endoscopy combined with FICE was significantly higher than that of magnifying endoscopy (P ＜0.05 ).ConclusionMagnifying endoscopy combined with FICE can reveal the structure of the pit,microvascular and demarcation line more clearly.The endoscopic diagnostic criteria is a more comprehensive description of the mucosal micro-morphological features of early gastric cancer.
