| 2 | White light endoscopy,narrow band imaging and chromoendoscopy with magnification in diagnosing colorectal neoplasia显示文摘AIM:To evaluate the sensitivity(Sn),specificity(Sp),positive predictive value(PPV) and negative predictive value(NPV) of 3 different techniques:high resolution white light endoscopy(WLE),Narrow Band Imaging(NBI) and Chromoendoscopy(CHR),all with magnification in differentiating adenocarcinomas,adenomatous and hyperplastic colorectal polyps.METHODS:Each polyp was sequentially assessed first by WLE,followed by NBI and finally by CHR.Digital images of each polyp with each modality were taken and stored.Biopsies or polypectomies were then performed followed by blinded histopathological analysis.Each image was blindly graded based on the Kudo's pit pattern(KPP).In the assessment with NBI,the mesh brown capillary network pattern(MBCN) of each polyp was also described.The Sn,Sp,PPV and NPV of differentiating hyperplastic(Type Ⅰ & Ⅱ-KPP,Type Ⅰ-MBCN) adenomatous(Types Ⅲ,Ⅳ-KPP,Type Ⅱ-MBCN) and carcinomatous polyps(Type Ⅴ-KPP,Type Ⅲ-MCBN) was then compared with reference to the final histopathological diagnosis.RESULTS:A total of 50 colorectal polyps(5 adenocarcinomas,38 adenomas,7 hyperplastic) were assessed.CHR and NBI [KPP,MBCN or the combined classification(KPP & MBCN)] were superior to WLE in the prediction of polyp histology(P < 0.001,P=0.002,P=0.001 and P < 0.001,respectively).NBI,using the MBCN pattern or the combined classification showed higher numerical accuracies compared to CHR,but this was not statistically significant(P=0.625,0.250).CONCLUSION:This feasibility study demonstrated that this combined classification with NBI could potentially be useful in routine clinical practice,allowing the endoscopist to predict histology with higher accuracies using a less cumbersome and technically less challenging method. | Rajvinder Singh Victoria Owen Anthony Shonde Philip Kaye Christopher Hawkey Krish Ragunath | 2009 | World Journal of Gastrointestinal Endoscopy2009，1，1： | 3 |
| 3 | Diagnosis of autoimmune gastritis by high resolution magnification endoscopy显示文摘胃的萎缩的内视镜的可视化通常不与常规内视镜检查法是可行的。放大内视镜检查法是有用的分析潜水艇没有织物的上皮的微脉管的建筑学以及粘膜表面微观结构活体检视。用这种技术,我们能描述正常胃的微脉管系统模式,我们也在自体免疫的萎缩性胃炎的二种情况中识别了典型模式。 | George K Anagnostopoulos Krish Ragunath Anthony Shonde Christopher J Hawkey | 2006 | World Journal of Gastroenterology2006，12，28： | 3 |
