早期胃癌和上皮内瘤变在放大内镜窄带成像技术下的表现
Research on manifestations of early gastric cancer and intraepithelial neoplasia under magnifying endoscopy with narrow-band imaging
摘要
Abstract
Objective To study the diagnostic efficacy of magnifying endoscopy with narrow-band imaging(ME-NBI)in the diagnosis of early gastric cancer and intraepithelial neoplasia,and their manifestations under ME-NBI.Methods In this retrospective research,we enrolled 131 cases of early gastric cancer and intraepithelial neoplasia.Then analyze the ME-NBI manifestations of lesions,compare the diagnostic efficacy of ME-NBI and white light endoscopy(WLI)+biopsy methods in early gastric cancer and intraepithelial neoplasia and study the ME-NBI manifestations of different degrees of lesions.Results The diagnostic accuracy of ME-NBI for diagnosing early gastric cancer,high grade intraepithelial neoplasia(HGIN)and low grade intraepithelial neoplasia(LGIN)was 77.96%,77.96%and 77.96%,respectively.The diagnostic accuracy of WLI+biopsy for above lesions was 60.53%,58.47%and 69.70%,respectively.There was no statistically significant difference in the accuracy of two diagnostic methods for LGIN(P>0.05),while there was a statistically significant difference in the accuracy of two diagnostic methods for early gastric cancer and HGIN(P<0.05).In LGIN,the highest rate of cerebral gyrus glandular duct emergence was 60.46%.The incidence of papillary and villous ducts is highest in HGIN and early gastric cancer,with rates of 57.14%and 52.00%,respectively.Conclusion ME-NBI has more diagnostic efficiency in early gastric cancer than WLI+biopsy.The demarcation line has better sensitivity in differentiated early gastric cancer and intraepithelial neoplasia.Micro-surface tube like villous,papillary structures has higher occurrence rates in early gastric cancer.The cerebral gyrus microglandular duct appeares significantly higher in LGIN than other groups.关键词
