智能染色技术内镜在鼻咽部病变诊断中的应用探索OACSTPCD

Objective To compare the diagnostic value of white light endoscopy and intelligent scan(i-Scan)endoscopy for nasopharyngeal masses.Methods We collected 127 patients with nasopharyngeal masses from January 2019 to December 2021 and obtained biopsy pathological results.From January 2019 to December 2020,59 cases were treated with white light endoscopy,and from January 2021 to December 2021,68 cases were treated with i-Scan endoscopy.Compare the accuracy of diagnosis between the two groups based on pathological results as the gold standard;Evaluate the microvascular morphology and lesion boundaries of nasopharyngeal masses under i-Scan endoscopy,and conduct correlation analysis with pathological results.Results The specificity and accuracy of i-Scan endoscopy in the diagnosis of nasopharyngeal masses were higher than those of white light endoscopy(91.80%and 86.00%,91.17%and 86.44%),and the sensitivity was lower than that of white light endoscopy(85.71%and 88.89%),but there was no significant difference(P>0.05).The diagnostic consistency of i-Scan group was slightly higher than that of white light group(Kappa=0.619 and 0.588);The lesion site boundary score,microvascular score,and their total score in i-Scan group were positively correlated with the pathological score(r=0.429,r=0.421,r=0.460),the differences were statistically significant(P<0.05);Typical disordered and twisted submucosal vessels(SV)and branching vessels(BV)were observed in nasopharyngeal carcinoma,most benign lesions could observe dilated and regularly distributed SV and BV,regardless of pathological malignancy,no obvious intraepithelial papillary capillary loop(IPCL)was observed in the nasopharynx.Conclusion The diagnostic efficacy of i-Scan endoscopy for nasopharyngeal masses is higher than that of white light endoscopy.
