ERCP诊治指南（2010版）（二）

胆管良恶性狭窄的ERCP诊治 一、胆管狭窄的ERCP诊断 1．良性和恶性胆管狭窄在临床上一般均以梗阻性黄疸和（或）胆管炎为主要表现,通过血液检验和一线的影像学检查（如腹部超声、CT、MRI或MRCP等）,通常可确立诊断。ERCP作为二线的检查手段,在对于上述检查仍不能确诊或已确诊需要介入治疗时使用,不建议单纯实施ERCP诊断。     

多种内镜检查方法联合应用对胆管狭窄性疾病的诊断价值

目的评估多种内镜检查方法联合应用对胆管狭窄性疾病的诊疗价值。方法回顾性分析36例胆管狭窄性疾病患者的诊断情况。36例患者均进行了超声内镜检查术（EUS）、经内镜逆行胰胆管造影术（ERCP）、胆管内超声检查术（IDUS）,胆道靶向刷检行细胞学涂片、液基薄层细胞学检查,并结合临床资料及组织学病理检查,综合诊断。结果最终诊断胆管恶性病变21例,其中胆管细胞癌9例、十二指肠乳头癌4例、胰腺癌侵犯胆总管4例、肝癌侵犯胆总管4例;胆管良性病变15例,其中胆总管结石9例、肝吸虫感染所致胆管狭窄4例、单纯胆管炎性狭窄1例、外部压迫所致胆管狭窄1例。EUS、ERCP、IDUS及ERCP＋IDUS对胆管狭窄性疾病鉴别诊断的准确率分别为77．8％、88．9％、91．7％、94．4％,ERCP、IDUS及ERCP＋IDUS均明显高于EUS（P均〈0．05）;ERCP＋IDUS对胆管狭窄性疾病鉴别诊断的敏感度、特异度、阳性预测值与阴性预测值分别为95．2％、93．3％、95．2％、93．3％,均高于EUS、ERCP及IDUS单独检查。胆道刷检细胞学、液基薄层细胞学或组织病理学检查,19例诊断为恶性狭窄,17例诊断为良性狭窄,对鉴别胆管狭窄性质诊断的敏感度为90．5％、特异度为100．0％、准确率为94．4％。结论对于胆管狭窄性病变,ERCP＋IDUS可使诊断准确率得到明显提高;联合应用ERCP＋IDUS＋病变胆管的靶向刷检等多种内镜检查方法,诊断准确率更高。     

管腔内超声对胰胆疾病诊断价值的初探

目的 评价管腔内超声(IDUS)检查在胰胆疾病中的诊断价值.方法 回顾性分析北京协和医院2006年7月至2007年8月期间,对19例胰胆疾病患者的ERCP与IDUS检查结果及其相关临床资料.结果 (1)19例患者中梗阻性黄疸17例,胰腺导管内乳头状黏液瘤(IPMT)2例.17例梗阻性黄疸中胆管癌6例,胰腺癌2例,胆囊癌2例,胆管结石合并胆管狭窄2例,自身免疫性胰腺炎2例,十二指肠乳头腺癌1例,十二指肠乳头腺瘤1例,硬化性胆管炎1例.19例诊断中11例经手术或组织病理学证实.(2)ERCP对胰胆疾病诊断的正确率为73.7%(14/19),IDUS对胰胆疾病诊断的正确率为84.2%(16/19),ERCP联合IDUS对胰胆疾病诊断的正确率89.5%(17/19).(3)ERCP对胆管良恶性狭窄鉴别诊断的敏感性和特异性分别为100.0%(11/11)和83.3%(5/6),IDUS对胆管良恶性狭窄鉴别诊断的敏感性和特异性分别为100.0%(11/11)和100.O%(6/6).(4)ERCP对胆管癌诊断的敏感性和特异性分别为83.3%(5/6)和60.0%(3/5),IDUS对胆管癌诊断的敏感性和特异性分别为100.0%(6/6)和40.0%(2/5).结论 ERCP检查同时进行IDUS检查能提高胰胆疾病的诊断率.IDUS对胆管良恶性狭窄的鉴别诊断具有较高的敏感性和特异性,但在具体区分恶性狭窄的病因上尚存在一定的困难.     

探讨胆汁肿瘤标志物对胆管良恶性疾病的诊断价值

目的探讨胆汁肿瘤标志物对胆管良恶性疾病的诊断价值。方法160例因胆道疾病需要ERCP治疗者,ERCP时取胆汁检测胆汁肿瘤标志物（CA19-9、CEA和CA242）和细菌培养。结果恶性狭窄组与良性疾病组间胆汁和血清CA19-9、CEA、CA242水平差异均有统计学意义（P〈0．05）;根据ROC曲线制定恶性狭窄的胆汁肿瘤标志物界限值：CA19-9239ku／L,CEA40ng／ml,CA24260ku／ml。CEA敏感度、准确度、阴性预测值与血液标志物比较差异有统计学意义（P〈O．05）。3种胆汁标志物的特异性与血清比较差异无统计学意义。胆管癌、胰腺癌、十二指肠乳头癌与胆管旁转移癌、肝癌比较CA19-9水平差异有统计学意义（P〈0．05）;无论是恶性狭窄组还是良性疾病组,细菌阳性胆汁与阴性胆汁组间CA19-9水平比较差异均有统计学意义（P〈0．05）。结论胆汁CA19-9、CEA、CA242水平对鉴别胆道良恶性疾病有一定帮助,但并不明显优于血清标志物。胆汁细菌感染可引起胆汁CA19-9水平升高,但不影响良恶性诊断结果。     

胆管腔内超声对鉴别胆管狭窄性质的临床价值研究

目的 探讨胆管腔内超声(IDUS)对于判断胆管狭窄性质的临床应用价值.方法 收集2006年至2010年因胆管狭窄行胆管腔内超声检查后手术患者,将IDUS结果与手术结果进行对照.结果 49例患者中良性狭窄6例,恶性狭窄43例;IDUS判断胆管狭窄性质的敏感度为97.7％( 42/43),特异度为83.3％ (5/6),阳性预测值为97.7％(42/43),阴性预测值为83.3％(5/6),准确性为95.9％(47/49);显著高于传统的影像学检查(B超、CT及MRCP).32例患者曾行胆道刷片检查,其中21例诊断为恶性狭窄,准确率为65.6％.所有胆道刷片诊断为恶性狭窄病例均已经被IDUS所诊断.结论 胆管腔内超声可以有效判断胆管狭窄的性质,指导临床治疗.ERCP术中IDUS基础上行胆道刷片对于胆管恶性狭窄诊断价值有限,但是对于明确病理诊断有一定的帮助.     

腔内超声联合ERCP、CA19—9对胆管良恶性狭窄的诊断

胆管狭窄多因胆管的良恶性疾病或毗邻脏器的压迫所致,由于难于取到病理活检,临床上对胆管良恶性狭窄诊断较困难。近年来随着医学影像技术的发展和应用,MRCP、ERCP、腔内超声检查（IDUS）等技术在临床逐步推广应用,胆管狭窄的诊断及良恶性鉴别水平有了极大的提高。本文对近年来在我中心就诊的胆管狭窄病例资料进行总结,分析IDUS联合ERCP、CA19—9对胆管良恶性狭窄的诊断情况。     

ERCP联合胆汁肿瘤标志物测定对可疑胰胆管疾病的诊断价值研究

目的探讨胆汁肿瘤标志物测定在ERCP对可疑胰胆管疾病诊断中的辅助作用。方法对经B超、MRCP、生化、血清肿瘤标志物等常规检查未能明确诊断的可疑胰胆管疾病患者,进行ERCP检查或对症治疗,同时行胆汁肿瘤标志物测定,选取29例明确诊断的病例分为良性和恶性组,比较2组在生化、肿瘤标志物上的差别,同时评估和比较B超、EUS、MRCP、ERCP、ERCP＋胆汁肿瘤标志物对可疑胰胆管疾病的诊断价值。结果生化、血清癌胚抗原（CEA）、血清CA19-9、胆汁CA19—9,在2组间差异无统计学意义,而胆汁CEA在恶性组中平均值高于良性组,且差异有统计学意义（P〈0．001）,ERCP联合胆汁CEA测定对可疑胰胆管疾病诊断准确率为69．0％（20／29）,高于单纯的B超6．9％（2／29）、EUS60．0％（6／10）、MRCP37．9％（11／D）和ERCP41．4％（12／29）。结论ERCP联合胆汁的CEA测定能进一步提高可疑胰胆管疾病诊断的准确性,对良恶性疾病的鉴别诊断有着辅助作用。     

Comparative studies of DU-PAN-2, carcinoembryonic antigen, and CA19-9 in the serum and bile of patients with pancreatic and biliary tract diseases: evaluation of the influence of obstructive jaundice

The levels of DU-PAN-2 antigen, carcinoembryonic antigen, and CA19-9 in serum and bile of patients with pancreatic and biliary tract diseases were measured. The sensitivities (true positive) of DU-PAN-2 in serum to pancreatic carcinoma (64%) and to biliary tract carcinoma (62%) were similar to those of CA19-9 in serum (69% and 72%, respectively). Nine of 18 (50%) patients with CA19-9-negative pancreatic carcinoma tested positive for DU-PAN-2. The sensitivities of CEA to pancreatic carcinoma (56%) and to biliary tract carcinoma (52%) were lowest. The measurement of these antigens in bile seemed to be of little diagnostic value in differentiating between malignant and benign diseases. False positives of these three assays occurred frequently in patients with benign pancreatic or biliary tract disease coupled with obstructive jaundice. After percutaneous transhepatic biliary drainage, serum DU-PAN-2 and CA19-9 levels returned to normal ranges in patients with benign diseases, but not in patients with carcinoma of the pancreas or of the biliary tract. Serum CA19-9 and DU-PAN-2 antigens are useful tumor markers for pancreatic and biliary tract carcinomas. Longitudinal assays of these antigens may be useful for the differential diagnosis of patients with obstructive jaundice.     

血清 CA19-9 水平在良性胆管疾病患者中的临床意义

背景: CA19-9是临床常用的肿瘤标记物,对胰胆系恶性肿瘤的阳性率较高,但良性胆管疾病中亦常见CA19-9水平升高。目的: 分析血清CA19-9水平在良性胆管疾病患者中的临床意义。方法: 选取2004年10月～2009年5月北京军区总医院的78例经ERCP证实的良性胆管疾病患者(60例胆总管结石和18例胆总管炎性狭窄)。所有患者于ERCP术前行血清CA19-9水平检测,并分析其在良性胆管疾病中的临床意义。结果: 39例(50.0%)患者血清CA19-9水平正常,其中胆总管结石26例(66.7%)。其余39例(50.0%)患者血清CA19-9水平升高,其中胆总管结石34例(87.2%);4例血清CA19-9水平1000U/ml者的年龄均65岁,并合并有严重化脓性梗阻性胆管炎或重症急性胰腺炎。16例血清CA19-9升高者于ERCP术后行复查,多数患者血清CA19-9水平明显下降。结论: 良性胆管疾病患者中血清CA19-9水平可升高,可作为预测胆管炎症程度的指标,尤其是在老年患者中。     

血清CA19-9对肝胆胰疾病的临床诊断价值

目的 观察血清CA19-9在肝胆胰良恶性疾病中的诊断和鉴别诊断价值.方法 回顾性调查2007年7月-2009年12月福建医科大学附属第一医院收治的180例伴有不同程度肝功能异常或胆管梗阻的肝胆胰良恶性疾病患者中血清CA19-9水平,并结合血清胆红素、肝转氨酶进行分析.结果 胰腺癌组和胆管癌组血清CA19-9水平较良性疾病组明显升高,差异有统计学意义（P＜0.05）,而肝细胞癌组与良性疾病组血清CA19-9水平比较,差异无统计学意义（P =0.143）;在恶性疾病中,胰腺癌组血清CA19-9水平明显高于胆管癌组和肝细胞癌组,差异有统计学意义（P ＜0.001）,胆管癌组则明显高于肝细胞癌组,差异有统计学意义（P=0.003）;血清CA19-9对胰腺癌、胆管癌、肝细胞癌的灵敏度分别为73.5％、53.8％、23.5％,胰腺癌和胆管癌灵敏度比较,差异无统计学意义（P =0.171）,但二者与肝细胞癌相比,灵敏度差异有统计学意义（P ＜0.0125）;良性疾病组血清CA19-9水平与胆红素水平呈明显正相关性（0.8＜r＜0.9,P ＜0.001）,与肝转氨酶相关性较弱（0.16 ＜r＜0.18,P＞0.10）,但恶性疾病组血清CA19-9与血清胆红素、肝转氨酶均无明显相关性（P＞0.10）;通过绘制ROC曲线确定血清CA19-9诊断胆胰癌的最佳阳性参考值为55.2 U/ml.结论 伴有不同程度的肝功能异常或胆管梗阻的肝胆胰疾病中,血清CA19-9对胆胰恶性肿瘤有一定的诊断和鉴别诊断价值,而对肝细胞癌的诊断价值不大;良性疾病中,不同程度的肝功能异常或者胆管梗阻可相应使血清CA19-9水平不同程度升高,但恶性疾病中血清CA19-9水平的高低主要与肿瘤本身表达强弱有关;使用CA19-9的最佳阳性参考值并联合检测其他肿瘤标志物可以明显提高其对胆胰癌的诊断效率.     

The utility of CA 19-9 in the diagnoses of cholangiocarcinoma in patients without primary sclerosing cholangitis

OBJECTIVES: The diagnosis of cholangiocarcinoma is often difficult, making management approaches problematic. A reliable serum tumor marker for cholangiocarcinoma would be a useful additional diagnostic test. Previous studies have demonstrated that elevated serum concentrations of CA 19-9, a tumor-associated antigen, have good sensitivity and specificity for cholangiocarcinoma in patients with primary sclerosing cholangitis. However, the value of this tumor marker for cholangiocarcinoma unassociated with primary sclerosing cholangitis is unclear. Thus, the aims of this study were to determine the usefulness of a serum CA 19-9 determination in the diagnosis of de novo cholangiocarcinoma. METHODS: We prospectively measured serum CA 19-9 concentrations in patients with cholangiocarcinoma (n = 36), nonmalignant liver disease (n = 41), and benign bile duct strictures (n = 26). Serum CA 19-9 concentrations were measured by an immunoradiometric assay (CIS Bio International) without knowledge of the clinical diagnosis. RESULTS: The sensitivity of a CA 19-9 value >100 U/ml in diagnosing cholangiocarcinoma was 53%. When compared with the nonmalignant liver disease and the benign bile duct stricture groups, the true negative rates were 76% and 92%, respectively. Patients with unresectable cholangiocarcinoma had significantly greater mean CA 19-9 concentrations compared to patients with resectable cholangiocarcinoma. CONCLUSIONS: These data suggest that the serum CA 19-9 determination is a useful addition to the available tests for the differential diagnosis of cholangiocarcinoma.     

Intraductal US in evaluation of biliary strictures without a mass lesion on CT scan or magnetic resonance imaging: significance of focal wall thickening and extrinsic compression at the stricture site

BACKGROUND AND OBJECTIVE: The clinical utility of intraductal US (IDUS) for evaluating biliary strictures has been limited because of a lack of easily recognized morphologic criteria to distinguish benign and malignant strictures. We studied the clinical value of 2 easily assessed IDUS findings: wall thickness and extrinsic compression at the stricture site. DESIGN AND SETTING: A retrospective, single-center study. PATIENTS AND METHODS: Forty-five patients without an identifiable mass on CT/magnetic resonance imaging, who underwent ERCP/IDUS for evaluation of biliary strictures were studied. IDUS pictures were reviewed specifically to measure wall thickness and to look for extrinsic compression at the stricture site. MAIN OUTCOME MEASUREMENTS AND RESULTS: The mean age of the patients was 64.2+/-13.3 years. Thirty patients had jaundice at presentation, and in 15 patients a stricture was suspected on imaging. The mean length of biliary strictures was 15.1+/-7.8 mm. Strictures were distal (distal common bile duct) in 25 patients and proximal (mid/proximal common bile duct or common hepatic duct) in 20 patients. Fourteen strictures were finally diagnosed to be malignant. Strictures in 20 patients were caused by extrinsic compression, and tissue diagnosis was readily obtained by EUS-FNA in all these patients. Of 25 strictures without extrinsic compression, 6 were malignant (wall thickness 9-16 mm) and 19 were benign (wall thickness相似文献
