摘要
目的 分析胆总管末端结石定性、定位诊断中彩色多普勒超声的应用价值.方法 选取 2020年 3 月至 2023 年 3 月我院收治的 94 例疑似胆总管末端结石患者,入组者均行彩色多普勒超声检查,以逆行胰胆管造影术(ERCP)诊断结果作为金标准,将彩色多普勒超声、ERCP对不同直径结石、单发或多发结石检出率进行比较,并分析彩色多普勒超声对胆总管末端结石的定性、定位诊断结果.结果 94 例患者经ERCP检查检出阳性 79 例,阴性 15 例;经彩色多普勒超声检查检出阳性 73 例,阴性 21 例;彩色多普勒超声对胆总管末端结石的诊断准确率、特异度及灵敏度分别为 83%、67%、86%;彩色多普勒超声对单发、多发结石检出率分别为 48%、30%;彩色多普勒超声对直径<0.5 cm、0.5～1.0 cm及＞1.0 cm结石检出率分别为 4%、35%、38%;彩色多普勒超声对胰腺段、壶腹段结石检出率分别为 41%、36%;彩色多普勒超声与ERCP检查对胆总管单发或多发结石检出率、不同直径结石检出率及定位诊断结果比较,均差异无统计学意义(P＞0.05).结论 胆总管末端结石诊断中彩色多普勒超声具有较高应用价值,可准确定位结石,为临床诊治提供可靠依据.
Abstract
Objective To analyse the application value of colour Doppler ultrasound in the qualitative and localization diagnosis of stones at the end of the common bile duct.Methods Ninety four patients with suspected common bile duct end stones admitted from March 2020 to March 2023 were selected,and all of them underwent colour ultrasound examination,and the diagnostic results of ERCP were used as the gold standard to compare the detection rates of colour ultrasound and ERCP for stones of different diameters,single or multiple stones,and to analyse the results of the qualitative and localisation diagnosis of common bile duct end stones by colour ultrasound.Results Seventy nine patients were detected positively and fifteen patients were detected negatively by ERCP;73 patients were detected positively and 21 patients were detected negatively by colour ultrasound;the diagnostic accuracy,specificity and sensitivity of colour ultrasound for stones at the end of the common bile duct were 83%,67%,and 86%,respectively;the detection rates of colour ultrasound for single-and multiple-occurring stones were 48%and 30%,respectively;and the diagnostic accuracy and specificity of colour ultrasound for stones with diameters of<The detection rates of colour ultrasound on single and multiple stones were 48%and 30%respectively;the detection rates of colour ultrasound on stones with diameters of<0.5 cm,0.5～1.0 cm and＞1.0 cm were 4%,35%and 38%respectively;the detection rates of colour ultrasound on pancreatic and jugular segments were 41%and 36%respectively;and the comparisons of colour ultrasound and ERCP on the detection rate of single or multiple stones of choledochal ducts,detection rate of stones with different diameters and the localization diagnosis results did not have statistical differences(P＞0.05).There was no statistical difference between colour ultrasound and ERCP examination.Conclusion Colour Doppler ultrasound is of high value in the diagnosis of stones at the end of the common bile duct,which can accurately locate the stones and provide a reliable basis for clinical diagnosis and treatment.
