摘　　要：目的探讨经腹壁超声、MSCT检查对胆总管结石所致老年ASC的临床应用价值。方法选取本院2017年6月至2019年7月收治46例总胆管结石所致ASC患者的临床资料。所有患者均进行经腹壁超声、MSCT检查,比较患者所得图像进行分析,以手术检查结果为基准,对经腹壁超声、MSCT对胆总管结石、ASC、结石+ASC检出率。结果经腹壁检查对胆总管结石检出率为76.08%,ASC检出率为73.91%,结石+ASC检出率为78.26%,明显低于MSCT检查(97.82%、95.65%、95.65%,P<0.05)。经腹壁超声检查,发现肝、内胆管及胆总管管壁回声有增强、厚度增厚,肝内胆管明显扩张(1cm到2.6cm)。急性期患者见肝脏肿大,回声增强,其中有3例患者可见肝脓肿表现。MSCT图像表现为胆道增宽,管壁存在广泛性毛糙增厚,胆汁密度低于腔内脓液密度,在患者梗阻段可见“新月征”、“环征”、“靶征”以及致密结节石影。结论MSCT检查对胆总管结石所致老年ASC检出率优于经腹壁超声检查,可为临床治疗方案选择提供参考,值得临床广泛应用。Objective To explore the clinical application value of transabdominal ultrasound and MSCT examination for ASC caused by common bile duct stones of elderly patients.Methods The clinical data of 46 patients with ASC caused by common bile duct stones treated in our hospital from June 2017 to July 2019 were selected.All patients underwent transabdominal ultrasound and MSCT examination.The images of patients were analyzed.The results of the surgical examination were used as a reference to compare the detection rates of transabdominal ultrasound,MSCT for common bile duct stones,ASC,stones+ASC.Results The detection rate of transabdominal ultrasound for common bile duct stones was 76.08%,the detection rate for ASC was 73.91%,the detection rate for stone+ASC was 78.26%,which was significantly lower than that of MSCT(97.82%,95.65%,95.65%,P<0.05).The transabdominal ultrasound showed The echoes in the wall of the liver,the inner bile duct,and the common bile duct were enhanced,the thickness was thickened,and the intrahepatic bile duct was significantly expanded(1 cm to 2.6 cm).In the acute phase,the liver of patients was swollen,and the echo was enhanced.Three patients showed liver abscesses.The MSCT images showed widening of the biliary tract.There was extensive roughness and thickening in the wall of the tube.The density of bile was lower than that of pus in the cavity.In the obstruction segment of the patient,the crescent sign,the ring sign,the target sign,and the dense nodular stone shadow were visible.Conclusion MSCT examination is superior to transabdominal wall ultrasound in the detection rate of ASC caused by common bile duct stones in elderly patients,which can provide a reference for clinical treatment,and it is worthy of clinical application.
