磁共振胆胰管造影在梗阻性黄疸诊断和治疗中的作用

目的：探讨磁共振胆胰管造影(MRCP)对梗阻性黄疸患梗阻定位和定性的诊断价值及对治疗的指导意义。方法：对48例梗阻性黄疸的患进行MRCP检查，34例(70．8％)行手术治疗，14例(29．2％)行非手术治疗。结果：48例患中45例(93．8％)可通过MRCP明确诊断，并经手术或临床证实；2例(4．1％)硬化性胆管炎需结合其他临床资料做出诊断；1例(2．1％)胆总管结石误诊为胆管癌。结论：MRCP对胆道疾患诊断具有无创性、高灵敏度、高准确率等优点，能为梗阻性黄疸患临床治疗提供有效依据。     

CASE OF FASCIOLIASIS: EXTRACTION WITH ENDOSCOPIC RETROGRADE CHOLANGIOGRAPHY

Fascioliasis is a worldwide zoonotic infection with fasciola hepatica and fasciola gigantica. The zoonoses are particularly endemic in sheep‐raising countries and are also endemic in Turkey. Clinical features of fascioliasis relate to the stage and intensity of infection. Fasciola hepatica infection comprises two stages: hepatic and biliary, with different signs and symptoms. Cholestatic symptoms may be sudden, but, in some cases, they may be preceded by a long period of fever, eosinophilia and vague gastrointestinal symptoms. We reported a case with fever and upper‐quadrant abdominal pain since 3 months that comes from an area endemic for fasciola hepatica, with suspected imaging about fasciola hepatica in common bile duct on ultrasonography. After that, fasciola hepatica was extracted with endoscopic retrograde cholangiography.     

胆道癌ERCP诊断(附49例分析)

本文报道用ERCP诊断胆管癌24例、胆囊癌6例、壶腹癌19例、共49例,都经手术或病理证实,诊断符合率为85.7％。 文章描述了胆道癌ERCP的X线表现。依造影所见把胆管癌分为阻塞型、狭窄型和息肉型。狭窄型又分闭塞型、环型及弥漫型三个亚型。胆管癌以阻塞型和闭塞型狭窄多见。胆囊癌表现为胆囊内基底宽广固定不变的充盈缺损。壶腹癌为壶腹部边缘不整的占位病变,可阻塞胆管或胰管或同时阻塞胰胆管。肝内胆管的软藤状改变是胆道恶性肿瘤的特征性表现。     

胆管癌误诊和漏诊的影像学分析

目的：分析胆管癌误诊和漏诊的原因，评价不同检查方法对肝门区胆管癌诊断的价值，提高胆管癌的影像学诊断和鉴别诊断水平。方法：收集31例临床和病理诊断为胆管癌的病例(ERCP检查31例，B超检查31例，25例CT检查，11例行MRCP检查)，回顾性分析不同检查方法的影像学表现。结果：31例中发生在肝门区的胆管癌25例。2例初次ERCP显示胆管内出血，再次行鼻胆管造影后诊断为胆管癌，4例合并有总胆管结石。6例为总胆管中下段癌。初次诊断准确性为90．3％。11例MRCP中9例显示病变，2例显示不满意，7例显示胆管或胆囊结石。25例CT中23例显示肝内胆管扩张，9例显示肝门区肿块，2例见后腹膜转移淋巴结，1例见肝内多发性转移瘤。12例初次诊断正确(48％)。B超检查23例提示肝内胆管扩张，6例提示总胆管结石，18例诊断为胆囊炎、胆囊结石，8例提示胆管占位(25．8％)。结论：良好的直接胆管造影是诊断胆管癌的金标准，MRCP可以在一定程度上准确显示病变的范围，是ERCP的良好补充，很大程度上取代了诊断性ERCP；CT诊断的关键在于显示扩张的胆管和梗阻的定位，肝门区梗阻多为胆管癌所致。多种影像检查方法的结合明显提高了诊断的准确性，对胆管癌治疗方案的选择有重要价值。
