内镜超声检查对胆总管结石的诊断价值 总被引:8,自引:1,他引:8
目的 探讨内镜超声检查(EUS)对胆总管结石的诊断价值。方法 回顾性总结近3年来术前B超、CT等检查未能确定胆总管结石而行EUS并经内镜乳头切开术(EST)取石或手术治疗证实者资料,共45例。结果 45例中,EUS诊断胆总管结石43例,另2例诊断胆管轻度扩张,经EST取出高位胆管小结石;EUS诊断胆总管结石者中,2例分别经EST和手术(合并胆囊结石),胆管内未见结石。其敏感度为95%,阳性预测值为95%。结石最大1、2cm,最小0.3cm,其中≤0.5cm者26例,45例中B超诊断4例可疑胆总管末端结石,2例怀疑壶腹周围占位性病变。CT诊断3例可疑胆总管结石,1例怀疑壶腹占位性病变。结论 EUS在诊断胆总管结石方面,不论胆管是否扩张,不论结石大小,都明显优于B超和CT,尤其是小结石,可与ERCP相媲美,而比ERCP更少侵袭性,更安全。 相似文献

为评估超声内镜检查术(endoscopic ultrasonography,EUS)对胆总管小结石的诊断价值,纳入2018年1月—2021年7月在东南大学附属中大医院住院并诊断为可疑胆总管结石的患者60例。所有患者于同一次住院期间行EUS及磁共振胰胆管成像(magnetic resonance cholangiopancreatography,MRCP)。以经内镜逆行胰胆管造影、开腹探查或腹腔镜胆总管探查结果为金标准,比较EUS及MRCP对胆总管结石的诊断结果,计算2种检查方法的灵敏度、特异度、阳性预测值、阴性预测值。结果显示,60例患者中46例确诊胆总管结石,EUS诊断准确43例,MRCP诊断准确35例;14例患者证实胆总管结石阴性,EUS诊断准确12例,MRCP诊断准确13例。EUS诊断灵敏度明显高于MRCP[93.48%(43/46)比76.09%(35/46),χ2=4.128,P=0.042]。结石直径≤1.0 cm者45例,其中EUS确诊42例,MRCP确诊34例(诊断准确率93.33%比75.56%,χ2=4.145,P=0.042);直径≤0.8 cm者39例,其中EUS确诊36例,MRCP确诊28例(诊断准确率92.31%比71.79%,χ2=4.266,P=0.039);直径≤0.5 cm者26例,其中EUS确诊24例,MRCP确诊16例(诊断准确率92.31%比61.54%,χ2=5.038,P=0.021)。在胆总管结石的诊断方面,EUS有明显的诊断优势,且诊断准确性不受结石大小的影响,因此对于临床高度怀疑胆总管结石但MRCP结果阴性的患者,需进一步行EUS。 相似文献

Background/Aims: The progression of endoscopy and devices as well as newly developed treatment methods have enabled endoscopic lithotomy. In this study, we examined to what degree is it possible to endoscopically treat patients who are diagnosed as having common bile duct stones. Methodology: Lithotomy was conducted using a backward side-viewing endoscope for patients without surgical history of upper gastrointestinal tract and patients with stomach reconstructed with Billroth-I method, using an ordinary endoscope for patients with stomach reconstructed with Billroth-II method (Bil-II) and using a double balloon endoscope for patients with difficulty in reaching the papilla or patients of Roux-en-Y anastomosis (R-Y). As for treatment methods, we selected endoscopic sphincterotomy as the first choice for papilla treatment and selected endoscopic papillary balloon dilation for patients with bleeding tendency or patients of Bil-II or R-Y. For patients with multiple stones or giant stones, lithotripsy was selected depending on judgment of the endoscopist. Results: Endoscopic complete lithotomy was successful in 97.7% (168/172). An accidental disease was observed in 2.9% (5/172). In one patient with the perforated gastrointestinal tract, a surgery was performed but others were mild. Conclusions: Common bile duct stones can be endoscopically treated safely with high rate. 相似文献

Background. It is controversial whether selective endoscopic sphincterotomy or routine laparoscopic bile duct exploration is the optimal treatment for choledocholithiasis. Magnetic resonance cholangio-pancreatography (MRCP) is a safe and accurate imaging modality; this study evaluated its use in a clinical algorithm for the management of suspected choledocholithiasis. Patients and methods. Consecutive patients presenting with suspected common bile duct (CBD) stones were managed according to an algorithm involving the selective use of MRCP to identify patients who required endoscopic sphincterotomy and bile duct clearance. Following radiological demonstration of a clear CBD, all patients were considered for cholecystectomy. Results. From 157 consecutive patients, 68 proceeded straight to endoscopic sphincterotomy, which was therapeutic in 59. Of 89 who underwent MRCP, choledocholithiasis was demonstrated in 29; subsequent endoscopic sphincterotomy was therapeutic in 22. MRCP demonstrated a clear CBD in the remaining 60 patients. Seventy-four patients subsequently underwent cholecystectomy, with a conversion rate of 9% and a median postoperative stay of 1 day. There were no instances of post-sphincterotomy pancreatitis or haemorrhage requiring transfusion. Conclusion. An algorithm involving selective MRCP with endoscopic sphincterotomy is a safe, effective means of managing suspected choledocholithiasis, particularly where the expertise, equipment or theatre time for laparoscopic bile duct exploration is not routinely available. 相似文献

Endoscopic sphincterotomy was performed within 28 days after cholecystectomy in 20 patients with retained common bile duct stones, of whom 15 (75%) underwent endoscopic sphincterotomy within the first week of surgery. Stone extraction was successful in all patients and no immediate complications were noted. Early endoscopic sphincterotomy for retained common bile duct stones was safe and effective in the early postoperative period. 相似文献

Asymptomatic common bile duct stones 总被引:6,自引:0,他引:6
Patients with asymptomatic bile duct stones exhibit typical signs, such as elevated liver function tests, dilated bile ducts on ultrasound, a history of jaundice, or pancreatitis. The incidence of asymptomatic bile duct stones is about 10%, but up to 2% of patients show no signs of the disease. Bile duct stones can be diagnosed by using clinical judgement, scoring systems, or discriminant function tests. Which diagnostic modality is most reliable, cost-effective and safe, varies with different hospitals. Which therapy is most effective, safe and the cheapest also varies with different departments, but in the future an increasing number of departments will use the one-stage laparoscopic approach. 相似文献

Symptomatic BDS commonly cause significant morbidity and attempt at stone removal should be attempted if possible. Complications of CBDS include biliary colic, jaundice, cholangitis and pancreatitis. Investigations aimed to predict the presence of stones within the bile duct include serum bilirubin, AST, ALP, common bile duct diameter and age as independent predictors of choledocholithiasis. TUS is a sensitive test in detecting bile duct dilatation but the sensitivity is reduced in its ability to detect choledocholithiasis. A NIH consensus statement found that ERC, MRC and EUS were comparable in their sensitivities, specificities and accuracy rates for detection of choledocholithiasis. ERC and stone removal using a balloon or basket is often performed following EST. EBD may be performed if patients have uncorrected coagulopathies but the risk of pancreatitis is higher than for EST (although the risk of bleeding complications is lower for EBD). ML is often required in difficult to remove CBDS and using this device, CBDS can be removed in 90–95% of cases. Other forms of lithotripsy including laser lithotripsy and EHL are confined to specialised centres and the evidence for their use is based on small studies. ESWL may clear stones from the bile duct in up to 93% of patients but frequently ERC and stone fragment removal is required post ESWL. The role of medical therapy in difficult to remove CBDS (or in CBDS in patients with severe co-morbid illness preventing ERC + stone removal) is still currently uncertain due to a lack of large randomised control trials. 相似文献

AIM: To describe characteristics of a poorly expandable (PE) common bile duct (CBD) with stones on endoscopic retrograde cholangiography.METHODS: A PE bile duct was characterized by a rigid and relatively narrowed distal CBD with retrograde dilatation of the non-PE segment. Between 2003 and 2006, endoscopic retrograde cholangiography (ERC) images and chart reviews of 1213 patients with newly diagnosed CBD stones were obtained from the computer database of Therapeutic Endoscopic Center in Chang Gung Memorial Hospital. Patients with characteristic PE bile duct on ERC were identified from the database. Data of the patients as well as the safety and technical success of therapeutic ERC were collected and analyzed retrospectively.RESULTS: A total of 30 patients with CBD stones and characteristic PE segments were enrolled in this study. The median patient age was 45 years (range, 20 to 92 years); 66.7% of the patients were men. The diameters of the widest non-PE CBD segment, the PE segment, and the largest stone were 14.3 ± 4.9 mm, 5.8 ± 1.6 mm, and 11.2 ± 4.7 mm, respectively. The length of the PE segment was 39.7 ± 15.4 mm (range, 12.3 mm to 70.9 mm). To remove the CBD stone(s) completely, mechanical lithotripsy was required in 25 (83.3%) patients even though the stone size was not as large as were the difficult stones that have been described in the literature. The stone size and stone/PE segment diameter ratio were associated with the need for lithotripsy. Post-ERC complications occurred in 4 cases: pancreatitis in 1, cholangitis in 2, and an impacted Dormia basket with cholangitis in 1. Two (6.7%) of the 28 patients developed recurrent CBD stones at follow-up (50 ± 14 mo) and were successfully managed with therapeutic ERC.CONCLUSION: Patients with a PE duct frequently require mechanical lithotripsy for stones extraction. To retrieve stones successfully and avoid complications, these patients should be identified during ERC. 相似文献

BACKGROUND Endoscopic sphincterotomy(EST) for the management of common bile duct stones(CBDS) is used increasingly widely because it is a minimally invasive procedure. However, some clinical practitioners argued that EST may be complicated by post-endoscopic retrograde cholangiopancreatography(ERCP)pancreatitis(PEP) and accompanied by a higher recurrence of CBDS than open choledochotomy(OCT). Whether any differences in outcomes exist between these two approaches for treating CBDS has not been thoroughly elucidated to date.AIM To compare the outcomes of EST vs OCT for the management of CBDS and to clarify the risk factors associated with stone recurrence.METHODS Patients who underwent EST or OCT for CBDS between January 2010 and December 2012 were enrolled in this retrospective study. Follow-up data were obtained through telephone or by searching the medical records. Statistical analysis was carried out for 302 patients who had a follow-up period of at least 5 years or had a recurrence. Propensity score matching(1:1) was performed to adjust for clinical differences. A logistic regression model was used to identify potential risk factors for recurrence, and a receiver operating characteristic(ROC)curve was generated for qualifying independent risk factors.RESULTS In total, 302 patients undergoing successful EST(n = 168) or OCT(n = 134) were enrolled in the study and were followed for a median of 6.3 years. After propensity score matching, 176 patients remained, and all covariates were balanced. EST was associated with significantly shorter time to relieving biliary obstruction, anesthetic duration, procedure time, and hospital stay than OCT(P <0.001). The number of complete stone clearance sessions increased significantly in the EST group(P = 0.009). The overall incidence of complications and mortality did not differ significantly between the two groups. Recurrent CBDS occurred in18.8%(33/176) of the patients overall, but no difference was found between the EST(20.5%, 18/88) and OCT(17.0%, 15/88) groups. Factors associated with CBDS recurrence included common bile duct(CBD) diameter > 15 mm(OR =2.72; 95%CI: 1.26-5.87; P = 0.011), multiple CBDS(OR = 5.09; 95%CI: 2.58-10.07; P< 0.001), and distal CBD angle ≤ 145°(OR = 2.92; 95%CI: 1.54-5.55; P = 0.001). The prediction model incorporating these factors demonstrated an area under the receiver operating characteristic curve of 0.81(95%CI: 0.76-0.87).CONCLUSION EST is superior to OCT with regard to time to biliary obstruction relief, anesthetic duration, procedure time, and hospital stay and is not associated with an increased recurrence rate or mortality compared with OCT in the management of CBDS. 相似文献

AIM:To evaluate the effect of cholecystokinin(CCK)during extracorporeal shockwave lithotripsy(ESWL)in the clearance of common bile duct(CBD)stones in endoscopic retrograde cholangiopancreatography(ERCP).METHODS:Between January 2007 and September2012,patients with large CBD stones who were treated with ESWL and ERCP were identified retrospectively.Patients were randomized in equal numbers to cholecystokinin(CCK)and no CCK groups.For each CCK case,a dose(3 ng/kg per min for 10 min)of sulfated octapeptide of CCK-8 was administered intravenously near the beginning of ESWL.ERCP was performed 4 h after a session of ESWL.The clearance rate of the CBD was assessed between the two groups.RESULTS:A total of 148 consecutive cases(CCK group:74,no CCK group:74)were tallied.Overall there were 234 ESWLs and 228 ERCPs in the 148 cases.The use of CCK showed a significantly higher rate of successful stone removal in the first ESWL/ERCP procedure(71.6%vs 55.4%,P=0.035),but resulted in similar outcomes in the second(42.8%vs 39.4%)and third(41.7%vs 40.0%)sessions,as well as total stone clearance(90.5%vs 83.8%).The use of mechanical lithotripsy was reduced in the CCK group(6.8%vs17.6%,P=0.023),and extremely large stone(≥30mm)removal was higher in the CCK group(72.7%vs41.7%,P=0.038).CONCLUSION:CCK during ESWL can aid with the clearance of CBD stones in the first ESWL/ERCP session.Mechanical lithotripsy usage was reduced and the extremely large stone(≥30 mm)clearance rate can be raised. 相似文献
