摘要
[目的]探讨微型超声探头联合内镜窄带成像技术(NBI)诊断早期肠癌的临床价值。[方法]选取126例大肠息肉样病变患者,均行微型超声探头联合NBI进行诊断,以病理检查结果为金标准,分析诊断结果。[结果]病理检查共检出230个息肉样病变,其中炎性及增生性息肉91个,腺瘤118个,腺癌21个。NBI诊断出NICEⅠ型90个,Ⅱ型117个,Ⅲ型23个。NBI对大肠肿瘤性病变的诊断敏感性、特异性、准确性、阳性预测值、阴性预测值分别为94.24%、90.11%、92.61%、93.57%、91.11%。微型超声探头对肠癌T1、T2、T3期的诊断符合率分别为100.00%、85.71%、80.00%,总体诊断符合率为90.48%。[结论]联合应用微型超声探头和内镜窄带成像技术能有效提高早期肠癌及癌前病变检出率。
[Objective]To investigate the value of miniature ultrasound probe combined with endoscopic Narrow Band Imaging diagnosis for early colorectal cancer.[Methods]126 cases of colorectal polypoid lesions patients were diagnosed by miniature ultrasound probe combined with NBI,analyses of diagnostic results with pathological findings as the gold standard.[Results]The pathological examination was detected 230 polypoid lesions,91 cases were inflammatory and hyperplastic polyps,118 cases were adenomas,21 cases were adenocarcinomas.NBI diagnosed 90 cases were NICE Ⅰ type,117 cases were Ⅱ type,23 cases were Ⅲ type.NBI colorectal neoplastic lesions diagnostic sensitivity,specificity,accuracy,positive predictive value,negative predictive values were 94.24%,90.11%,92.61%,93.57%,91.11%.Miniature ultrasound probe for cancer T1,T2,T3 of the diagnosis rates were 100.00%,85.71%,80.00%,overall accuracy was90.48%.[Conclusion]Miniature ultrasound probe combined with NBI can effectively improve the early detection rate of colorectal cancer and precancerous lesions.
