Study on the effectiveness of colonoscopy narrow band imaging combined with reversal technique in improving the detection rate and diagnostic efficiency of polypoid lesions in the right colon
摘要
Abstract
Objective To investigate the effect of colonoscopy narrow band imaging(NBI)combined with reversal technique on improving the detection rate of polypoid lesions in the right colon and the diagnostic efficacy of the combination of the two techniques.Methods 660 patients who underwent colonoscopy from March 2023 to March 2025 were selected.The patients were divided into the NBI group,the reversal group and the combined group by the random number table method,with 220 cases in each group.Diagnostic protocols varied across groups:the NBI group underwent NBI during colonoscopy,the reversal group received the colonic reversal technique,while the combined group experienced both NBI and reversal techniques concurrently.Comparative analysis focused on polypoid lesion detection rates within the right colonic segments among all three groups.All the detected polyps were taken for pathological examination,and the polyps were divided into neoplastic polyps and non-neoplastic polyps.To compare the diagnostic efficacy of three methods for right colon polypoid lesions.Results The detection rates of re-detected neoplastic polyps,total re-detected polyps(neoplastic+non-neoplastic),total detected neoplastic polyps and total detected polyps(neoplastic+non-neoplastic)in the combined group were significantly higher than those in the reversal group(P<0.0167).The detection rates of re-detected neoplastic polyps and the total number of recurrent polyps(neoplastic+non-neoplastic)in the NBI group were significantly higher than those in the reversal group(P<0.0167).The detection rates of polypoid lesions<5 mm and flat polypoid lesions in the combined group were significantly higher than those in the inversion group(P<0.0167).For detecting polypoid abnormalities in the right colon,NBI demonstrated diagnostic performance metrics of 93.22％sensitivity,95.59％specificity,and 94.49％accuracy.The colonoscopic reversal method yielded values of 68.97％sensitivity,89.58％specificity,and 78.30％accuracy when examining similar lesions.When combining both NBI and reversal techniques,the composite evaluation achieved superior results with 97.10％sensitivity,98.61％specificity,and 97.87％diagnostic accuracy for right colonic polypoid lesions.The sensitivity and accuracy of NBI and NBI+reversal technique in the diagnosis of polypoid lesions in the right colon were significantly higher than those of the reversal technique(P<0.0167).Conclusion Colonoscopy NBI combined with reversal technique can effectively increase the detection rate of polypoid lesions in the right colon,and its diagnostic efficacy is significantly higher than that of colonoscopy reversal technique alone.关键词
