| 1.1 Objective:To explore the value of magnifying endoscopy and narrow band imaging in diagnosing the early gastric cancer,and to identify weather there are some relationships between the micro vascular、microsurface and the invasive depth、pathlogical type of early gastric cancer.1.2 Method:.we retrospectively analised 69 patients diagnosed as early gastric cancer by endoscopy examnation,then got endoscopic treatment within 2 weeks during June 2015 to Octomober 2018.Based on pathlogical results,we investigated the value of ME-NBI and white light endoscoy with biposy in diagnosing the early gastric cancer.At the same time,we selected Chi square test or fisher test to explore the relationship between microvascular、microsurface and the invasive depth、pathlogical type of early gastric cancer.If P<0.05,it was considered statistically significant,then we can make a conclusion that there are some relationships among them;otherwise,it makes nonsense.1.3 Result:The clinical information from 69 patients suggested that the accuracy、sensitivity and specifity of ME-NBI in diagnosing early gastric cancer is 95%、88%and 57%;for the biposy,it is 96%、82%and 71%.What’s more,the invasive depth and pathlogical type of early gastric cancer have no connection with the changes of microvascular and microsurface.1.4 Conclusion:Firstly,ME-NBI and white light endoscopy with biposy both have high value in diagnosing the early gastric cancer,but ME-NBI is not equal to white light endoscopy with biposy.Nowdays,biposy is still first choice for the diagnosis of early gastric cancer.Secondly,the abnormals of microvascular and microsurface have no relationship with the invasive depth and pathlogical type of early gastric cancer.By observing the pattern of microvascular and microsurface,the endoscopy physicans could only assure that weather the lession is cancerous or not,but they are not able to predict the invasive depth and pathlogical types of lessions preciously. |
