Methods MRI and MRCP of 80 cases with obstructive jaundice by malignant disease were analyzed retrospectively. Diagnosis on MPCP were contrasted with pathology-based diagnosis. The findings and accuracy of MRCP-based diagnosis of malignant obstructive jaundice were analyzed. Results The positive rate of the orientation diagnosis and the detection rate of bile ducts on the proximal side of obstruction was 100.0% . The diagnostic accuracy of malignant obstruction was 83. 8% . MRCP was found to have highly diagnosit-ic specificity for determining the location and quality of obstruction. Conclusion MRCP have significance for clinical diagnosis of malignant obstructive jaundice. The diagnostic accuracy of MRCP for malignant obstructive jaundice was remarkadly higher.%目的探讨磁共振胰胆管成像(magnetic resonance cholangiopancreatography,MRCP)对恶性梗阻性黄疸的诊断价值,提高MRCP 对恶性梗阻性黄疸的诊断准确性.方法总结80例恶性病变致梗阻性黄疸的MRCP 及常规MRI(磁共振成像)的影像学特征,将MRCP诊断结果与手术病理检查结果进行对照,分析MRCP诊断的准确性及各种恶性梗阻性黄疸MRCP的特征性表现.结果 MRCP对恶性梗阻性黄疸的定位诊断及梗阻近端胆管显示率为100.0%;对恶性梗阻性黄疸的的诊断准确率为83.8%,定位、定性诊断特异性高.结论 MRCP对恶性梗阻性黄疸的定位诊断准确率达100.0%;在定性诊断中有重要地鉴别诊断价值;能明显提高对恶性梗阻性黄疸的诊断准确率.【总页数】2页(P280-281)【作者】梁长华;毛华杰;王清华;王红坡;孙凤霞【作者单位】453100,新乡医学院第一附属医院;453100,新乡医学院第一附属医院;453100,新乡医学院第一附属医院;453100,新乡医学院第一附属医院;453100,新乡医学院第一附属医院【正文语种】中文【中图分类】R730.41【相关文献】1.2D MRCP、3DMRCP结合冠状位T2WI对胆总管结石诊断价值的对比研究 [J], 刘金有;唐广山;周光礼2.B超、CT、MRI/MRCP联合CA19-9检测对恶性梗阻性黄疸的诊断价值 [J], 姜战武;张新江;高占虎;戴占英;毛永贤;董春燕;王俊霞;刘文礼3.2D-MRCP、3D-MRCP结合冠状位B-TFE序列对胆总管结石诊断价值的比较[J], 郏格拉;张保红;刘建中;魏五洲;姜义杰4.良恶性梗阻性黄疸螺旋CT、MRI、MRCP的诊断价值分析 [J], 张丽蓉5.良恶性梗阻性黄疸螺旋CT、MRI、MRCP的诊断价值分析 [J], 张丽蓉[1]因版权原因,仅展示原文概要,查看原文内容请购买。
梗阻性黄疸的超声诊断目的探讨超声在梗阻性黄疸中的诊断意义。
方法选择16例梗阻性黄疸患者,行超声检查,分析超声检查结果。

肝外梗阻性黄疸15例,其中肝外胆管结石7例,肝门部胆管癌1例,胆囊癌3例,壶腹癌1例,胰头癌3例。
结论超声在梗阻性黄疸中有重要的临床检查意义,值得借鉴。
[Abstract] Objective To explore the diagnostic significance of ultrasound in obstructive jaundice. Methods 16 cases with obstructive jaundice were selected and they were given ultrasound examination,the results of ultrasound examination was analyzed. Results The results of ultrasonic inspection:1 case was intrahepatic obstructive jaundice,and this case was metastatic liver cancer.15 cases were extrahepatic obstructive jaundice,and these cases included 7 cases with extrahepatic bile duct stone,1 case with hilar bile duct carcinoma,3 cases with gallbladder carcinoma,1 case with ampullary carcinoma,3 cases with carcinoma of head of pancreas. Conclusion The ultrasound has important significance clinical examination in obstructive jaundice,and it is worthy of learning.[Key words] Obstructive jaundice;Ultrasound;Diagnosis梗阻性黄疸是由胆汁在肝内至十二指肠乳头之间的任何部位发生阻塞而引起的[1-3],分为肝内梗阻性黄疸和肝外梗阻性黄疸。

【摘要】目的探讨多层螺旋CT对十二指肠乳头旁憩室所致梗阻性黄疸的CT表现,提高对该病的诊断及鉴别诊 断水平。方法本组20例中,男12例,女8例,憩室均发生于十二指肠乳头周围2 cm范围内。所有病例均为突 发性黄疸,13例伴右上腹痛,7例伴全腹压痛及反跳痛,l2例为上消化道慢性炎症急性发作,10例有上消化道 溃疡史,疼痛无规律性,制酸药物不能缓解。以双盲法的形式,分别由2位资深影像学医师对本组病例的CT表 现进行回顾性分析,并与上消化道钡餐造影、十二指肠镜检查及手术结果对照。结果本组病例中有十二指肠乳 头旁憩室28个,单发l5例,多发(2~3个)5例。憩室形态、大小差异较大,最小者0.5 cmx0.6 am,最大者8.0 am ̄ 9.0 cm。15个憩室内见气液平面,20例均显示胆总管和(或)胰管扩张。本组病例螺旋CT扫描及重建显示效果 较好,可清楚显示十二指肠乳头旁憩室内羽毛状黏膜及炎性改变所致梗阻性黄疸的CT异常表现,与手术、上消 化道钡餐造影及十二指肠镜所见基本符合。本组误漏诊2例,其他病例定位、定性均准确。结论多层螺旋CT 作为一种无创性检查技术,对十二指肠乳头旁憩室所致梗阻性黄疸的CT表现有较高的特征性。对其诊断及鉴 别诊断有较高的临床应用价值。 『关键词】十二指肠乳头旁憩室;梗阻性黄疸;螺旋cT;表现 【中图分类号】R445.3 [文献标识码】A 【文章编号】1674—4721(2013)02(b)一01O9—03
CT manifestation of obstructive jaundice caused by duodenal papillary diverticula JIN Guoqing LIU Yuxia LI Yongchi ZHA0 Meiying Depa ̄ment of Radiology,the People S Hospital of Puyang City in He'nan Province,Puyang 457000,China [Abstract]Objective To explore the CT manifestation of obstructive jaundice caused by duodenal diverticula with multi-slice spiral CT scan,in order to improve the skills of diagnosis and differential diagnosis of this disease.Meth- ods Among 20 cases in this group,12 cases were male,8 cases were female.All diverticula were located in less than 2 am from the duodenal papilla.Sudden jaundice occurred in all cases;fight upper abdominal pain occurred in 1 3 cases,7 cases with abdominal tenderness and rebound tenderness.1 2 cases were due to acute attack of chronic upper digestive inflammation,10 patients had a history of upper digestive ulcers,in which,pain was irregular,and anti—acid drugs were not a11eviative.Double-blind method was adopted.Two experienced imaging physician retrospectively ana- lyzed CT scans and compared with findings of upper digestive barium examination,endoscopic findings and operations. Results In this group,28 duodenal diverticula were observed,single in 15 cases,multiple(2-3)in five cases.The dif- ferenee of shape and size of diverticula were significant,in which,the smallest one was 0.5cm×0.6cm,and the largest was 8.0 am×9.Ocm.Air fluid level was found in 15 cases.dilatation of choledoch and/or pancreatic duct were seen in 20 cases.In this study,the imaging of spiral CT scanning and reconstruction were very good,and the CT abnormalities of feathers like mucosa in duodenal diverticula and inflammatory changes caused by obstructive jaundice can be clear— ly observed,which was basically in accordance with the manifestation showed in operation,upper digestive barium imaging and endoscopic findings.Two cases were misdiagnosed,and the location and characteristics of diseases in oth— er cases were all accurate.Conclusion Multi—slice CT as a noninvasive technology has a higher characteristic CT find— ing for obstructive jaundice caused by duodena1 diverticula.and has high clinical value for diagnosis and differential diagnosis of obstructive jaundice caused by duodenal papillary diverticulla. r [Key words]Duodenal papilla diverticula;Obstructive jaundice;Spiral CT;Manifestation j
