胆胰疾病行治疗性内镜逆行性胰胆管造影术811例临床分析

目的探讨治疗性内镜逆行性胰胆管造影术(ERCP)在胆胰疾病中的应用价值及其并发症的防治。方法回顾性分析上海中医药大学附属普陀医院2001年9月至2006年9月行治疗性ERCP的811例胆胰疾病患者的临床资料。结果562例胆总管结石患者中行乳头切开术(EST)474例,行乳头气囊扩张术(EPBD)88例,结石总清除率为95%;244例恶性胆道梗阻患者中183例行鼻胆管引流(ENBD),61例行胆道内支架引流术(ERBD);5例恶性胆胰管梗阻患者行胆胰管双支架引流术。行胆道内支架引流可使血清胆红素明显下降,胰管支架置入可使上腹部疼痛有一定程度减轻。并发症:乳头切开处出血13例(1.6%),均发生于EST术后;急性胰腺炎43例(5.3%),其中发生于EST术后32例,EPBD术后7例,ENBD术后2例,ERBD术后2例;EST术后发生急性胆囊炎4例(0.5%);全组死亡2例(0.2%)。结论应用十二指肠镜行治疗性ERCP去除胆管结石,控制胆道炎症,解除胆胰管恶性梗阻是一种理想的微创外科方法,熟练的技术与细致的围手术期处理是防治并发症关键。     

十二指肠乳头旁憩室对诊疗性内镜逆行胰胆管造影术的影响

背景：临床上将十二指肠乳头旁2～3cm范围内的憩室称为十二指肠乳头旁憩室（JPD），约占十二指肠憩室的90％。JPD与胆胰疾病的发生密切相关，并对诊疗性内镜逆行胰胆管造影术（ERCP）的操作有一定影响。目的：探讨JPD与胆胰疾病的关系及其对诊疗性ERCP的影响。方法：回顾性分析JPD与十二指肠乳头的关系及其对造影成功率、治疗性ERCP及其并发症的影响。结果：本组行诊疗性ERCP患者中发现JPD67例，发现率为23、3％。JPD患者61．2％合并有胆管结石．ERCP造影成功率97．0％，胆管显影率91．0％．71．6％的患者行治疗性ERCP。结论：JPD患者易合并胆管结石，给诊疗性ERCP带来困难和风险，但只要操作者耐心、细心、小心，即使是治疗性ERCP也是安全的。     

有关内镜下逆行胰胆管造影术的几点思考

内镜下逆行胰胆管造影术（endoscopic retrograde cholangiopancreatography，ERCP）诞生于60年代后期，1974年内镜下乳头括约肌切开术首次报道。随着影像技术的进步，磁共振胆胰管成像因其无创、无射线、无需造影剂等优点己逐步取代诊断性ERCP，成为胰胆疾病首选的诊断方法。ERCP逐渐转向胰胆疾病的治疗，在短短几十年中ERCP取得了巨大的成就，成为当今胰胆疾病重要的治疗手段。[第一段]

Prospective evaluation of magnetic resonance cholangiopancreatography in patients with biliary disease: comparative study with conventional ultrasonography and endoscopic retrograde cholangiopancreatography: Diagnostic algorithm

BACKGROUND: Magnetic resonance cholangiopancreatography is an accurate technique that can replace invasive diagnostic methods of the biliary and pancreatic duct. AIMS: Our aim was to assess sensitivity and specificity of magnetic resonance cholangiopancreatography and ultrasonography using the results of endoscopic retrograde cholangiopancreatography as reference, and to establish a diagnostic algorithm under which circumstances magnetic resonance cholangiopancreatography can replace endoscopic retrograde cholangiopancreatography. PATIENTS: Eighty-three patients with suspicion of biliary disease based on clinical, biochemical and ultrasonography findings were studied. METHODS: Ultrasonography, magnetic resonance cholangiopancreatography and endoscopic retrograde cholangiopancreatography were performed, comparing the results of the techniques for the determination of their sensitivity and specificity. RESULTS: Sensitivity and specificity results obtained by magnetic resonance cholangiopancreatography were: 100 and 92.8% when dilated ducts were detected (n=61); 97.4 and 97.2% in the diagnosis of choledocholithiasis (n=38); 100 and 96.7% in malignant lesions (n=14) and 81.8 and 98.4% when biliary ducts were normal. The percentage of images of diagnostic quality was 97.6%. Sensitivity and specificity achieved by ultrasonography was: 100 and 57.1% in detection of dilatation, 71 and 97.2% in choledocholithiasis, 92.8 and 96.7% in malignancy and 66.6 and 96.8% in normal ducts. CONCLUSIONS: Magnetic resonance cholangiopancreatography is a technique with high sensitivity and specificity in the evaluation of biliary ducts. Thus, magnetic resonance cholangiopancreatography may replace diagnostic endoscopic retrograde cholangiopancreatography for purely diagnostic purposes, following an initial clinical and ultrasonographic exam.     

Prospective study of diagnostic value of magnetic resonance cholangiopancreatography versus endoscopic retrograde cholangiopancreatography in cholangiopancreatic diseases

OBJECTIVE: To compare the diagnostic value of magnetic resonance cholangiopancreatography (MRCP) versus endoscopic retrograde cholangiopancreato­graphy (ERCP) in the detection of cholangiopan­creatic diseases via a prospective study. METHODS: Magnetic resonance cholangiopancreatography was performed in 63 patients with suspected cholangiopancreatic diseases and followed by ERCP within 24 h. The MRCP and ERCP images were analyzed and compared. RESULTS: Of the 63 patients studied, 56 (88.9%) were correctly diagnosed by using ERCP and seven (11.1%) by using percutaneous transhepatic cholangio­graphy (PTC); however, all these patients were successfully diagnosed by using MRCP. Cholangio­pancreatic diseases were diagnosed by MRCP with a sensitivity of 98.2%, a specificity of 83.3%, a misdiagnostic rate of 16.7% and a missed diagnostic rate of 1.8%. The total concordance rate of MRCP, ERCP and PTC was 85.7%. For specific conditions, the concordance rates were as follows: biliary calculi 100%; tumors of the bile duct 92.9%; papillary lesions 70.6%; hepatic distomiasis 66.7%; chronic pancreatitis 100%. The complications associated with ERCP were five cases of acute pancreatitis and one case of perinephric abscess. The patient with perinephric abscess had previously had a B‐II operation. The complication rate associated with ERCP was 9.5% (6/63), but no complications were associated with MRCP. CONCLUSION: We conclude that MRCP is as effective as ERCP for the diagnosis of bile duct lesions, such as biliary calculi and tumors, but not for papillary lesions and liver fluke infections. Although MRCP can be used in patients who can’t tolerate ERCP or when there are contraindications to using ERCP, it should not be used for therapeutic purposes.     

磁共振胰胆管成像和直接胰胆管造影对胆胰疾病诊断价值自身对比的前瞻性研究

目的 比较直接胰胆管造影（ERCP和PTC）和磁共振胰胆管成像（MRCP）对胆胰疾病的诊断价值。方法 临床怀疑胆胰系疾病63例。每例先行MRCP,在此后24h内行ERCP。影像科和内镜医师分别报告自己所见结果,待研究结束后,以ERCP或PTC为参照标准统一对比分析。结果 63例行ERCP中,成功率为88.9%（56/63例）,7例ERCP失败者改行PTC检查成功;所有MRCP均获成功,成功率为100.0%;MRCP的灵敏度为98.2%、特异度83.3%、误诊率为16.7%、漏诊率为1.8%。MRCP和ERCP（或PTC）总符合率85.7%,其中在胆系结石及胆管肿瘤分别为100.0%和92.9%,乳头病病变为70.6%（12/17例）,在慢性胰腺炎和肝吸虫的诊断符合率分别为3/3和66.7%。63例ERCP者,术后并发胰腺炎5例、肾周脓肿1例（为B-Ⅱ术后）,并发症发生率为9.5%（6/63例）;而MRCP无并发症发生。结论 对胆管内疾病,MRCP可达到ERCP的单纯诊断水平,而对乳头部病变（尤其是小病变）和肝吸虫,MRCP却无法与ERCP相比拟。对不能耐受ERCP及禁忌症者,MRCP是较好的选择。MRCP的最大不便在于不能同时进行治疗。     

Current status of endoscopic retrograde cholangiopancreatography in patients with surgically altered anatomy

Endoscopic retrograde cholangiopancreatography(ERCP)in patients with surgically altered anatomy must be performed by a highly experienced endoscopist.The challenges are accessing the afferent limb in different types of reconstruction,cannulating a papilla with a reverse orientation,and performing therapeutic interventions with uncommon endoscopic accessories.The development of endoscopic techniques has led to higher success rates in this group of patients.Device-assisted ERCP is the endoscopic procedure of choice for high success rates in short-limb reconstruction;however,these success rate is lower in long-limb reconstruction.ERCP assisted by endoscopic ultrasonography is now popular because it can be performed independent of the limb length;however,it must be performed by a highly experienced and skilled endoscopist.Stent deployment and small stone removal can be performed immediately after ERCP assisted by endoscopic ultrasonography,but the second session is needed for other difficult procedures such as cholangioscopy-guided electrohydraulic lithotripsy.Laparoscopic-assisted ERCP has an almost 100%success rate in longlimb reconstruction because of the use of a conventional side-view duodenoscope,which is compatible with standard accessories.This requires cooperation between the surgeon and endoscopist and is suitable in urgent situations requiring concomitant cholecystectomy.This review focuses on the advantages,disadvantages,and outcomes of various procedures that are suitable in different situations and reconstruction types.Emerging new techniques and their outcomes are also discussed.     

Diagnosis of mild chronic pancreatitis （Cambridge classification）： Comparative study using secretin injection-magnetic resonance cholangiopancreatography and endoscopic retrograde pancreatography

AIM： To investigate the usefulness of secretin injection- MRCP for the diagnosis of mild chronic pancreatitis.
METHODS： Sixteen patients having mild chronic pancreatitis according to the Cambridge classification and 12 control subjects with no abnormal findings on the pancreatogram were examined for the diagnostic accuracy of secretin injection-MRCP regarding abnormal branch pancreatic ducts associated with mild chronic pancreatitis （Cambridge Classification）, using endoscopic retrograde cholangiopancreatography （ERCP） for comparison.
RESULTS： The sensitivity and specificity for abnormal branch pancreatic ducts determined by two reviewers were respectively 55%-63% and 75%-83% in the head, 57%-64% and 82%-83% in the body, and 44%-44% and 72%-76% in the tail of the pancreas. The sensitivity and specificity for mild chronic pancreatitis were 56%-63% and 92%-92%, respectively. Interobserver agreement （K statistics） concerning the diagnosis of an abnormal branch pancreatic duct and of mild chronic pancreatitis was good to excellent.
CONCLUSION： Secretin injection-MRCP might be useful for the diagnosis of mild chronic pancreatitis.

Pancreatitis after endoscopic retrograde cholangiopancreatography: A narrative review

Acute post-endoscopic retrograde cholangiopancreatography pancreatitis (PEP) is a feared and potentially fatal complication that can be as high as up to 30% in high-risk patients. Pre-examination measures, during the examination and after the examination are the key to technical and clinical success with a decrease in adverse events. Several studies have debated on the subject, however, numerous topics remain controversial, such as the effectiveness of prophylactic medications and the amylase dosage time. This review was designed to provide an update on the current scientific evidence regarding PEP available in the literature.     

ERCP结合EPT对胆囊切除术后患者诊治价值的探讨

目的 回顾性研究逆行性胰胆管造影（ERCP）结合乳头肌切开术（EPT）对胆囊切除术后患者的诊治价值。方法 170例胆囊切除术后症状再发或反复发作患者,接受ERCP检查和EPT等治疗,诊断结果与B超作对照。同时动态观察内镜下介入诊治术后临床表现的改变。不良反应及血清淀粉酶的变化及高淀粉酶血症的分布情况。结果 经ERCP结合EPT等术后患者临床症状显著改善;与B超对照ERCP对胆囊切除术后胆总管残余结石的诊断率显著提高（P＜0．001）,对胆总管扩张程度的诊断价值显著优于B超（P＜0．05）,并能发现许多B超检查不能发现的胆胰病变;术后主要不良反应表现为出血、高淀粉酶血症,ERCP结合EPT等治疗组高淀粉酶的发生率显著高于单纯ERCP操作组（P＜0．01）。经积极地处理后短期内出血控制,血清淀粉酶多在3日内转为正常。结论 对胆囊切除术后患者,ECRP结合EPT不失为一项非常有价值、安全的诊治措施。
