Suspected common bile duct stones: reduction of unnecessary ERCP by pre-procedural imaging and timing of ERCP. Surg Endosc 2023; 37:1194-1202. [PMID: 36163565 PMCID: PMC9944135 DOI: 10.1007/s00464-022-09615-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/24/2022] [Accepted: 09/07/2022] [Indexed: 12/07/2022]
Abstract
BACKGROUND Endoscopic retrograde cholangiopancreatography (ERCP) is the procedure of choice to remove sludge/stones from the common bile duct (CBD). In a small but clinically important proportion of patients with suspected choledocholithiasis ERCP is negative. This is undesirable because of ERCP associated morbidity. We aimed to map the diagnostic pathway leading up to ERCP and evaluate ERCP outcome. METHODS We established a prospective multicenter cohort of patients with suspected CBD stones. We assessed the determinants that were associated with CBD sludge or stone detection upon ERCP. RESULTS We established a cohort of 707 patients with suspected CBD sludge or stones (62% female, median age 59 years). ERCP was negative for CBD sludge or stones in 155 patients (22%). Patients with positive ERCPs frequently had pre-procedural endoscopic ultrasonography (EUS) or magnetic resonance cholangiopancreatography (MRCP) imaging (44% vs. 35%; P = 0.045). The likelihood of ERCP sludge and stones detection was higher when the time interval between EUS or MRCP and ERCP was less than 2 days (odds ratio 2.35; 95% CI 1.25-4.44; P = 0.008; number needed to harm 7.7). CONCLUSIONS Even in the current era of society guidelines and use of advanced imaging CBD sludge or stones are absent in one out of five ERCPs performed for suspected CBD stones. The proportion of unnecessary ERCPs is lower in case of pre-procedural EUS or MRCP. A shorter time interval between EUS or MRCP increases the yield of ERCP for suspected CBD stones and should, therefore, preferably be performed within 2 days before ERCP.

Abstract
OBJECTIVES There is a paucity of literature assessing the impact of endoscopic retrograde cholangiopancreatography (ERCP) availability at hospitals and the management of acute biliary pancreatitis (ABP). Thus, we sought to evaluate the impact of ERCP availability on the clinical outcomes of ABP. METHODS The Nationwide Inpatient Sample (2004-2013) was reviewed to identify adult inpatients (≥18 years) with ABP. Clinical outcomes (mortality, severe acute pancreatitis, and health care resource utilization) between hospitals that perform ERCP versus hospitals that do not perform ERCP were compared using multivariate and propensity score-matched analyses. RESULTS A majority of the non-ERCP hospitals were rural (73%) in location. Multivariate analysis demonstrated that the lack of ERCP availability was independently associated with increased mortality from ABP (odds ratio, 1.83; 95% confidence interval, 1.16-2.88). A propensity score-matched cohort analysis confirmed a significant increase in mortality from ABP in non-ERCP hospitals (1.1% vs 0.53%; odds ratio, 2.08; 95% confidence interval, 1.05-4.15, P = 0.037) compared with ERCP hospitals. CONCLUSIONS This national survey reveals increased mortality for patients with ABP admitted to hospitals lacking ERCP services. While there is a need to increase ERCP availability in rural areas, optimizing strategies for early transfer of patients with ABP to hospitals with ERCP availability can potentially offset these limitations.

Abstract
Each year choledocholithiasis results in biliary obstruction, cholangitis, and pancreatitis in a significant number of patients. The primary treatment, ERCP, is minimally invasive but associated with adverse events in 6% to 15%. This American Society for Gastrointestinal Endoscopy (ASGE) Standard of Practice (SOP) Guideline provides evidence-based recommendations for the endoscopic evaluation and treatment of choledocholithiasis. The Grading of Recommendations Assessment, Development and Evaluation (GRADE) framework was used to rigorously review and synthesize the contemporary literature regarding the following topics: EUS versus MRCP for diagnosis, the role of early ERCP in gallstone pancreatitis, endoscopic papillary dilation after sphincterotomy versus sphincterotomy alone for large bile duct stones, and impact of ERCP-guided intraductal therapy for large and difficult choledocholithiasis. Comprehensive systematic reviews were also performed to assess the following: same-admission cholecystectomy for gallstone pancreatitis, clinical predictors of choledocholithiasis, optimal timing of ERCP vis-à-vis cholecystectomy, management of Mirizzi syndrome and hepatolithiasis, and biliary stent therapy for choledocholithiasis. Core clinical questions were derived using an iterative process by the ASGE SOP Committee. This body developed all recommendations founded on the certainty of the evidence, balance of risks and harms, consideration of stakeholder preferences, resource utilization, and cost-effectiveness.

Abstract
BACKGROUND Numerous models have been developed to predict choledocholithiasis. Recent work has shown that these algorithms perform suboptimally. Identification of clinical predictors with high positive and negative predictive value would minimize adverse events associated with unnecessary diagnostic endoscopic retrograde cholangiopancreatography (ERCP) while limiting the use of expensive tests including magnetic resonance cholangiopancreatography (MRCP) and endoscopic ultrasound (EUS) for indeterminate cases. METHODS Consecutive unique inpatients who received their first ERCP at Los Angeles County Medical Center between January 2010 and November 2016 for suspected bile duct stones were reviewed. The primary outcome was the proportion of patients with specific combinations of liver enzyme patterns, transabdominal ultrasound, and clinical features who had stones confirmed on ERCP. As a secondary outcome, we assessed the performance of the American Society for Gastrointestinal Endoscopy (ASGE) risk stratification algorithm in our population. RESULTS Of the 604 included patients, bile duct stones were confirmed in 410 (67.9%). Detailed assessment of liver enzyme patterns alone and in combination with clinical features and imaging findings yielded no highly predictive algorithms. Additionally, the ASGE high-risk criterion had a positive predictive value of only 68% for stones. For the 236 patients for whom MRCP was performed, this imaging modality was shown to have highest predictive value for the presence of stones on ERCP. CONCLUSION Exhaustive exploration of various threshold values and dynamic patterns of liver enzymes combined with clinical features and basic imaging findings did not reveal an algorithm to accurately predict the presence of stones on ERCP. The ASGE risk stratification criteria were also insensitive in our population. Though desirable, there may be no "perfect" combination of clinical features that correlate with persistent bile duct stones. MRCP or EUS may be considered to avoid unnecessary ERCP and associated complications.

Abstract
OBJECTIVES We aimed to investigate the roles of endoscopic ultrasonography (EUS) and magnetic resonance cholangiopancreatography (MRCP) in detecting the causes of acute pancreatitis after negative computed tomography (CT) findings. METHODS Demographic characteristics, blood test results, the severity of pancreatitis, and definite or possible etiology of pancreatitis by EUS and MRCP were evaluated prospectively in 65 consecutively admitted patients after negative CT findings. RESULTS Endoscopic ultrasonography and/or MRCP confirmed the definite causes of pancreatitis in 47.7% (31/65) (choledocholithiasis, 25; pancreatic divisum, 3; pancreatic cancer, 1; and pancreatic intraductal papillary mucinous neoplasm, 1). The possible causes were cholelithiasis in 75.4%, pancreaticobiliary common channel (PBCC) in 70.8%, and both in 89.2%. The diagnostic values of EUS were higher than MRCP for choledocholithiasis (35.4% vs 12.3%, P < 0.05). Cholelithiasis and the common bile duct diameter were independent factors for the definite etiology of acute pancreatitis. Choledocholithiasis was inversely associated with PBCC, and the common bile duct diameter was the only independent factor associated with PBCC. CONCLUSIONS Endoscopic ultrasonography is a useful imaging modality for detecting definite or possible causes of acute pancreatitis. A PBCC as well as biliary lithiasis could be not uncommon causes of acute pancreatitis after negative CT findings.

Abstract
OBJECTIVE Since increasing acute pancreatitis (AP) severity is significantly associated with mortality, accurate and rapid determination of severity is crucial for effective clinical management. This study investigated the value of the revised Atlanta classification (RAC) and the determinant-based classification (DBC) systems in stratifying severity of acute pancreatitis. METHODS This retrospective observational cohort study included 480 AP patients. Patient demographics and clinical characteristics were recorded. The primary outcome was mortality, and secondary outcomes were admission to intensive care unit (ICU), duration of ICU stay, and duration of hospital stay. RESULTS Based on the RAC classification, there were 295 patients with mild AP (MAP), 146 patients with moderate-to-severe AP (MSAP), and 39 patients with severe AP (SAP). Based on the DBC classification, there were 389 patients with MAP, 41 patients with MSAP, 32 patients with SAP, and 18 patients with critical AP (CAP). ROC curve analysis showed that the DBC system had a significantly higher accuracy at predicting organ failure compared to the RAC system (p < .001). Multivariate regression analysis showed that age and ICU stay were independent risk factors of mortality. CONCLUSION The DBC system had a higher accuracy at predicting organ failure. Age and ICU stay were significantly associated with risk of death in AP patients. A classification of CAP by the DBC system should warrant close attention, and rapid implementation of effective measures to reduce mortality.

Abstract
Background/Aims Endoscopic retrograde cholangiopancreatography (ERCP) is the initial therapy recommended for patients with high likelihood of choledocholithiasis. To determine whether endoscopic ultrasonography (EUS) can prevent diagnostic ERCPs in patients with high probability of choledocholithiasis and inconclusive ultrasonography (US). Methods All patients with high likelihood of choledocholithiasis and negative US underwent EUS. ERCP was performed for the patients who showed a definite stone/sludge on EUS. Patients without choledocholithiasis were followed up for 3 months. The primary outcome was avoidance of diagnostic ERCP. Results We included 78 patients (51 women; 27 men). Of these, 25 and 7 (total 41%) were diagnosed with choledocholithiasis and sludge, respectively; stone/sludge was removed in 96.9% of the patients. EUS ruled out choledocholithiasis in 38 patients (48.7%). Two of them were found to have choledocholithiasis on follow-up. The sensitivity, specificity, positive and negative predictive value of EUS for detecting choledocholithiasis were 93.9%, 97.3%, 96.9%, and 94.7%, respectively. Unnecessary ERCP was avoided in 57.7% of the patients by using the EUS-first approach. Conclusions EUS is a highly accurate and safe procedure. EUS can replace ERCP as the initial investigation in patients with a high probability of choledocholithiasis. It avoids unnecessary ERCP; hence, decreasing related costs and complications.

Abstract
Background/Aims EUS can detect bile duct stones (BDS) that are undetectable on multidetector computed tomography (MDCT). BDS associated with acute biliary pancreatitis (ABP) are small and tend to be excreted spontaneously. This study evaluated the usefulness of early EUS in patients with ABP and undetectable BDS on MDCT. Methods Forty-one patients with ABP and undetectable BDS on MDCT underwent EUS within 24 hours of admission and were diagnosed with BDS, sludge, dilated common bile duct (CBD), or normal CBD. ERCP was performed in patients with BDS, sludge, or clinical deterioration. The diagnostic yield and the effects of early EUS on morbidity, mortality, and the length of hospitalization were evaluated. Results EUS detected BDS or sludge in 48.8% of patients examined. BDS was the diagnosis in 13 patients, sludge in seven, and neither for 21 patients. ERCP was performed in 20 patients with BDS or sludge, in two patients with coexisting cholangitis, and in one patient with worsening liver function tests. ERCP identified BDS in 12 patients and sludge in seven. No lesions were diagnosed in four patients by ERCP. All patients improved, and the length of hospitalization in patients with ERCP was 9.0 days, without ERCP 7.1 days. Two patients with major complications by ERCP were hospitalized for a prolonged time. Conclusions Early EUS may be useful to select patients for therapeutic ERCP in cases of suspected ABP with undetectable BDS on MDCT.

Abstract
Predicting the presence of a persistent common bile duct (CBD) stone is a difficult and expensive task. The aim of this study is to determine if a previously described protocol-based scoring system is a cost-effective strategy. The protocol includes all patients with gallstone pancreatitis and stratifies them based on laboratory values and imaging to high, medium, and low likelihood of persistent stones. The patient's stratification then dictates the next course of management. A decision analytic model was developed to compare the costs for patients who followed the protocol versus those that did not. Clinical data model inputs were obtained from a prospective study conducted at The Mount Sinai Medical Center to validate the protocol from Oct 2009 to May 2013. The study included all patients presenting with gallstone pancreatitis regardless of disease severity. Seventy-three patients followed the proposed protocol and 32 did not. The protocol group cost an average of $14,962/patient and the non-protocol group cost $17,138/patient for procedural costs. Mean length of stay for protocol and non-protocol patients was 5.6 and 7.7 days, respectively. The proposed protocol is a cost-effective way to determine the course for patients with gallstone pancreatitis, reducing total procedural costs over 12 %.

Abstract
INTRODUCTION Choledocholithiasis, being the most common cause of extrahepatic cholestasis, is diagnosed on the basis of clinical symptoms, laboratory findings, and imaging results. An important diagnostic and also therapeutic procedure performed in patients with choledocholithiasis is retrograde cholangiopancreatography (ERCP). However, due to the high rate of complications associated with ERCP, the decision on its implementation should be preceded by a thorough analysis of the case, aimed at confirmation of the diagnosis. MATERIAL AND METHODS The present study is a retrospective analysis of 86 patients qualified for ERCP due to suspected choledocholithiasis. The diagnosis was based on clinical symptoms and/or laboratory and/or imaging results. The presence of one or more of the three abovementioned criteria was a key to classify patients in one of three risk groups of choledocholithiasis: high, intermediate and low. RESULTS In the high-risk group, where choledocholithiasis was confirmed by clinical symptoms, laboratory findings and results of imaging tests, the accuracy of diagnosis was 100%. In the intermediate-risk group - choledocholithiasis diagnosed on the basis of clinical symptoms and laboratory results - the accuracy of diagnosis was approximately 81.5% (p < 0.05). In the low-risk group, in which choledocholithiasis was diagnosed only on the basis of clinical symptoms, diagnosis accuracy was approximately 50% (p < 0.05). CONCLUSIONS The combination of clinical symptoms, laboratory tests and imaging findings allows patients to be classified into three risk groups of choledocholithiasis: high, intermediate and low. Taking into account the probability of choledocholithiasis and the risk of ERCP complications, only patients from high and intermediate risk groups should be qualified for the procedure.

Cost-effectiveness analysis of endoscopic ultrasound versus magnetic resonance cholangiopancreatography in patients with suspected common bile duct stones. PLoS One 2015; 10:e0121699. [PMID: 25799113 PMCID: PMC4370382 DOI: 10.1371/journal.pone.0121699] [Citation(s) in RCA: 25] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/11/2014] [Accepted: 02/17/2015] [Indexed: 12/26/2022] Open
Abstract
BACKGROUND Patients with suspected common bile duct (CBD) stones are often diagnosed using endoscopic retrograde cholangiopancreatography (ERCP), an invasive procedure with risk of significant complications. Using endoscopic ultrasound (EUS) or Magnetic Resonance CholangioPancreatography (MRCP) first to detect CBD stones can reduce the risk of unnecessary procedures, cut complications and may save costs. AIM This study sought to compare the cost-effectiveness of initial EUS or MRCP in patients with suspected CBD stones. METHODS This study is a model based cost-utility analysis estimating mean costs and quality-adjusted life years (QALYs) per patient from the perspective of the UK National Health Service (NHS) over a 1 year time horizon. A decision tree model was constructed and populated with probabilities, outcomes and cost data from published sources, including one-way and probabilistic sensitivity analyses. RESULTS Using MRCP to select patients for ERCP was less costly than using EUS to select patients or proceeding directly to ERCP ($1299 versus $1753 and $1781, respectively), with similar QALYs accruing to each option (0.998, 0.998 and 0.997 for EUS, MRCP and direct ERCP, respectively). Initial MRCP was the most cost-effective option with the highest monetary net benefit, and this result was not sensitive to model parameters. MRCP had a 61% probability of being cost-effective at $29,000, the maximum willingness to pay for a QALY commonly used in the UK. CONCLUSION From the perspective of the UK NHS, MRCP was the most cost-effective test in the diagnosis of CBD stones.

Abstract
BACKGROUND Endoscopic ultrasonography is accurate, safe, and cost-effective in diagnosing common bile duct stones, thus suggesting the possibility to avoid invasive endoscopic retrograde cholangiopancreatography. AIM To prospectively evaluate the diagnostic and therapeutic performance of early endoscopic ultrasonography in suspected choledocholithiasis. PATIENTS AND METHODS All consecutive patients presenting to the Emergency Department with suspicion of choledocholithiasis between January 2010 and January 2012 were evaluated and categorized as low, moderate, or high probability of choledocholithiasis, according to accepted criteria. Endoscopic endosonography was carried out within 48 h from the admission and endoscopic retrograde cholangiopancreatography was performed soon in case of confirmed choledocholithiasis. RESULTS Overall 179 patients were included: 48 (26.8%) were classified as low, 65 (36.3%) as moderate, and 66 (36.9%) as high probability of choledocholithiasis. Of the 86 patients with common bile duct stones at endoscopic endosonography, endoscopic retrograde cholangiopancreatography confirmed the finding in 79 (92%). By multivariate analysis only the common bile duct diameter proved an independent predictor of common bile duct stones. CONCLUSIONS Early endoscopic endosonography is accurate in identifying choledocholithiasis allowing immediate endoscopic treatment and significant spare of unnecessary endoscopic retrograde cholangiopancreatography. This approach can be useful as a triage test to select patients not needing endoscopic retrograde cholangiopancreatography, allowing, in selected cases, their early discharge.

Abstract
This guideline presents recommendations for the management of patients with acute pancreatitis (AP). During the past decade, there have been new understandings and developments in the diagnosis, etiology, and early and late management of the disease. As the diagnosis of AP is most often established by clinical symptoms and laboratory testing, contrast-enhanced computed tomography (CECT) and/or magnetic resonance imaging (MRI) of the pancreas should be reserved for patients in whom the diagnosis is unclear or who fail to improve clinically. Hemodynamic status should be assessed immediately upon presentation and resuscitative measures begun as needed. Patients with organ failure and/or the systemic inflammatory response syndrome (SIRS) should be admitted to an intensive care unit or intermediary care setting whenever possible. Aggressive hydration should be provided to all patients, unless cardiovascular and/or renal comorbidites preclude it. Early aggressive intravenous hydration is most beneficial within the first 12-24 h, and may have little benefit beyond. Patients with AP and concurrent acute cholangitis should undergo endoscopic retrograde cholangiopancreatography (ERCP) within 24 h of admission. Pancreatic duct stents and/or postprocedure rectal nonsteroidal anti-inflammatory drug (NSAID) suppositories should be utilized to lower the risk of severe post-ERCP pancreatitis in high-risk patients. Routine use of prophylactic antibiotics in patients with severe AP and/or sterile necrosis is not recommended. In patients with infected necrosis, antibiotics known to penetrate pancreatic necrosis may be useful in delaying intervention, thus decreasing morbidity and mortality. In mild AP, oral feedings can be started immediately if there is no nausea and vomiting. In severe AP, enteral nutrition is recommended to prevent infectious complications, whereas parenteral nutrition should be avoided. Asymptomatic pancreatic and/or extrapancreatic necrosis and/or pseudocysts do not warrant intervention regardless of size, location, and/or extension. In stable patients with infected necrosis, surgical, radiologic, and/or endoscopic drainage should be delayed, preferably for 4 weeks, to allow the development of a wall around the necrosis.

Abstract
Advances in biliary imaging have improved making accurate diagnoses of the presence and causes of biliary obstruction. Abdominal ultrasound is a useful screening tool because it is highly specific for choledocholithiasis. New developments in CT and MRI have also been useful in the diagnosis of biliary disease. Although diagnosis of biliary disease can be achieved in a noninvasive manner, there are limitations to modern MRI and CT cholangiographic techniques; their use may not be necessary or cost effective. MRI and CT imaging of the biliary tract provides opportunities for less-invasive diagnostic techniques but should be used judiciously before interventional endoscopy.

Abstract
It is imperative for gastroenterologists to understand the different formations of bile duct stones and the various medical treatments available. To minimize the complications of endoscopic retrograde cholangiopancreatography (ERCP), it is critical to appropriately assess the risk of bile duct stones before intervention. Biliary endoscopists should be comfortable with the basic techniques of stone removal, including sphincterotomy, mechanical lithotripsy, and stent placement. It is important to be aware of advanced options, including laser and electrohydraulic stone fragmentation, and papillary dilatation for problematic cases. The timing and need for ERCP in those who require a cholecystectomy is also a consideration.

Abstract
Although the effectivity of an urgent endoscopic retrograde cholangio-pancreatography was documented, some aspects relating to this method are still debated. Timing of this procedure has not been established yet. Indications for urgent endoscopic retrograde cholangio-pancreatography with stone extraction from the common bile duct in patients with biliary pancreatitis remains controversial. Biliary decompression and drainage is the cornerstone of acute cholangitis treatment. The timing of endoscopic retrograde cholangio-pancreatography should be based on the grade of the severity of the disease. Using endoscopic retrograde cholangio-pancreatography, the accurate diagnosis and treatment of bile leaks in a timely manner is imperative to limit associated morbidity and mortality. Difficulty in cannulating the common bile duct is one of the main risk factors for pancreatitis occurring after the procedure. Alternative techniques to facilitate difficult cannulation are discussed. Organized training and introduction of objective measures of the investigator's competence are emphasized to improve the performance of the procedure in Hungary.

Abstract
BACKGROUND Endoscopic ultrasonography (EUS) has emerged as an accurate diagnostic alternative to endoscopic retrograde cholangiopancreatography (ERCP). The aim of this study was to perform a systematic review of all randomized controlled trials of EUS-guided ERCP versus ERCP alone in patients with suspected choledocholithiasis. METHODS The search for eligible studies was carried out using the MEDLINE, Cochrane Central Register of Controlled Trials, and Science Citation Index electronic databases. Meta-analysis was conducted using a random-effects model. RESULTS Four trials containing 213 patients randomized to EUS-guided ERCP and 210 to ERCP alone were selected. In the EUS-guided ERCP group, ERCP was avoided in 143 patients (67.1 per cent) when EUS did not detect choledocholithiasis. The use of EUS significantly reduced the risk of overall complications (relative risk 0.35 (95 per cent confidence interval (c.i.) 0.20 to 0.62); P < 0.001) and post-ERCP acute pancreatitis (relative risk 0.21 (95 per cent c.i. 0.06 to 0.83); P = 0.030). CONCLUSION By performing EUS first, ERCP may be safely avoided in two-thirds of patients with common bile duct stones. Application of EUS in the selection of patients for therapeutic ERCP significantly reduces the complication rate.

Abstract
BACKGROUND EUS is being increasingly utilized for the diagnosis of choledocholithiasis and microlithiasis, especially in patients with biliary colic. Simultaneously, there is also a rising interest in the use of EUS for therapeutic interventions. OBJECTIVES Our goal was to assess the effectiveness of EUS-directed common bile duct (CBD) stone removal to compare its safety and effectiveness with ERCP-directed intervention. DESIGN Interim results of a prospective, randomized, single-center blinded clinical trial. SETTING A single tertiary care referral center. PATIENTS Fifty-two patients with uncomplicated CBD stones were prospectively randomized to CBD cannulation and stone removal under EUS or ERCP guidance. MAIN OUTCOME MEASUREMENTS AND INTERVENTIONS: Primary outcome measure was the rate of successful cannulation of the CBD. Secondary outcome measures included successful removal of stones and overall complication rates. RESULTS CBD cannulation followed by stone extraction was successful in 23 of 26 patients (88.5%) in the EUS group (I) versus 25 of 26 patients (96.2%) in the ERCP group (II) (95% CI, -27.65%, 9.88%). Overall, there were 3 complications in the EUS group and 4 complications in the ERCP group. LIMITATION The current study is an interim report from a single center report and performed by a single operator. CONCLUSIONS Our preliminary analysis indicates that outcomes following EUS-guided CBD stone retrieval are equivalent to those following ERCP. EUS-related adverse events are similar to those following ERCP. ERCP and EUS-guided stone retrieval appears to be equally effective for therapeutic interventions of the bile duct. Additional studies are required to validate these preliminary results and to determine predictors of success of EUS-guided stone removal.

Abstract
BACKGROUND EUS may be used to reduce the need of diagnostic ERCP. OBJECTIVE Our purpose was to investigate the benefits and safety of an EUS-guided versus an ERCP-guided approach in the management of suspected biliary obstructive diseases caused by choledocholithiasis, in whom a US study is not diagnostic. DESIGN A randomized study. SETTING A university medical unit. PATIENTS Patients with clinical, biochemical, or radiologic suspicion of biliary obstruction. INTERVENTIONS In the EUS group, therapeutic ERCP was performed at the same EUS session if a lesion was found. In the ERCP group, therapeutic treatment was carried out at the discretion of the endoscopist. MAIN OUTCOME MEASUREMENTS The number of ERCPs avoided, procedure-related complications, and recurrent biliary symptoms on follow-up at 1 year. RESULTS Thirty-three patients were randomized to EUS and 32 to ERCP. Three patients (9.4%) had failed ERCPs, whereas all EUS procedures were successful. Nine (27.3%) patients in the EUS group were found to have biliary lesions that were all treated by ERCP. In the ERCP group, 7 (22%) patients had biliary lesions detected that were treated in the same session. More patients had serious complications (bleeding, acute pancreatitis, and umbilical abscess) in the ERCP group. One patient in each group had recurrent biliary symptoms during follow-up. With EUS used as a triage tool, diagnostic ERCP and its related complications could be spared in 49 (75.4%) patients. CONCLUSIONS In patients suspected to have biliary obstructive disease, EUS is a safe and accurate test to select patients for therapeutic ERCP.

Abstract
The close proximity of the endoscopic ultrasound probe to the pancreas results in superior spatial resolution compared to CT scan and MRI. In addition, endoscopic ultrasound (EUS) is a minimally invasive procedure that does not share the relatively high complication rate of ERCP. Due to these advantages, EUS has evolved into an important technique to assess pancreatobiliary disease. This review will discuss the role of EUS in patients with pancreatitis. The indications can be divided into acute pancreatitis and chronic pancreatitis. In acute pancreatitis, EUS is used to determine the etiology; in suspected chronic pancreatitis it is helpful to establish the diagnosis. Lastly, this review will discuss biliary pancreatitis with suspicion for persistent choledocholithiasis.

Abstract
BACKGROUND Endosonography (EUS) and endoscopic retrograde cholangiopancreatography (ERCP) are highly accurate techniques for evaluating common bile duct stones. AIM To compare the clinical impact and costs of EUS- and ERCP-based strategies for evaluating patients with suspected common bile duct stones but normal transabdominal imaging. METHODS The costs of EUS- vs. ERCP-based strategies were compared in patients with suspected acute biliary obstruction from common bile duct stones but normal transabdominal imaging. RESULTS Over a 15-month period, 110 patients were recruited. EUS detected a common bile duct lesion in 73% (common bile duct stones: 68%; pancreatic cancer: 2%; ampulla tumour: 2%; cholangiocarcinoma: 1%). The sensitivity, specificity, positive predictive value and negative predictive value of EUS were 98%, 100%, 100% and 93%, respectively. EUS prevented 30% unnecessary ERCP. The mean difference in cost per patient between EUS- and ERCP-based strategies was US$166. When stratified according to clinical indications, an EUS-based strategy was costlier only in suspected biliary sepsis. Costs were similar when the indications were cholestatic jaundice, acute pancreatitis and cholestasis. CONCLUSION EUS prior to biliary interventions in patients with suspected common bile duct stones prevented unnecessary ERCP. It allowed a definitive diagnosis to be made prior to more invasive procedures.

Abstract
The rate of choledocholithiasis at the time of elective surgery after mild acute biliary pancreatitis is still unclear because it decreases rapidly after the onset. The aims of this study are as follows: (1) To investigate whether the incidence of choledocholithiasis in mild biliary pancreatitis is higher than in patients with symptomatic cholelithiasis. (2) To evaluate the usefulness of intraoperative cholangiography in the diagnosis of unsuspected choledocholithiasis in mild pancreatitis. Prospective study including 130 patients undergoing laparoscopic surgery and classified into two groups: mild biliary pancreatitis (n = 44) and symptomatic cholelithiasis (n = 86). Choledocholithiasis was evaluated by endoscopic cholangiopancreatography, magnetic resonance, and intraoperative cholangiography. Preoperatively, choledocholithiasis was identified in five patients with symptomatic cholelithiasis and two with biliary pancreatitis (5.81 vs 4.54%; p = 0.472). In 117 cases (90%), intraoperative cholangiography was successfully performed, identifying unsuspected choledocholithiasis in five patients of the colelithiasis group and in three in the group of pancreatitis (5.81 vs 6.81%; p = 0.492). The total number of patients with choledocholithiasis in the whole series was 15 (11.5%); 11.6% in colelithiasis group vs 11.4% in biliary pancreatitis group; p = 0.605. The rate of choledocholithiasis was not significantly different between the groups of patients with mild acute biliary pancreatitis and symptomatic cholelithiasis. Intraoperative cholangiography identified unsuspected choledocholithiasis in 6.81% of patients with mild acute biliary pancreatitis.

Abstract
BACKGROUND Numerous published studies have shown the high diagnostic performance of both EUS and MRCP compared with ERCP for the detection of choledocholithiasis. DESIGN We undertook a systematic review of all published randomized, prospective trials that compared EUS with MRCP with the primary aim being to compare the overall diagnostic accuracy for the detection of choledocholithiasis in patients with suspected biliary disease. METHODS A MEDLINE review was performed. We identified 5 randomized, prospective, blinded trials comparing MRCP and EUS for the detection of choledocholithiasis, with subsequent ERCP or intraoperative cholangiography as a criterion standard. The study-specific variables for EUS and MRCP for choledocholithiasis were calculated from the data, and analyses were performed by using aggregated variables (sensitivity, specificity, positive and negative predictive values, and likelihood ratios). RESULTS The pooled data set consisted of 301 patients. The aggregated sensitivities of EUS and MRCP for the detection of choledocholithiasis were 0.93 and 0.85, respectively, whereas their specificities were 0.96 and 0.93, respectively. The aggregated positive predictive values for EUS and MRCP were 0.93 and 0.87, respectively, with the corresponding negative predictive values of 0.96 and 0.92, respectively. Positive likelihood ratios were >10 for both tests, and corresponding negative likelihood ratios approached 0.10 for both tests. No statistically significant differences between EUS and MRCP were found in our analysis. CONCLUSIONS EUS and MRCP have high diagnostic performance overall. Our analysis showed no statistically significant difference between the modalities. We recommend taking into consideration other factors, such as resource availability, experience, and cost considerations in deciding between these 2 tests.

Abstract
BACKGROUND MRCP and EUS have replaced ERCP in the diagnosis of biliary diseases, but the latter is needed for treatment. This study evaluates a new approach in the management of common bile duct stones, by using an oblique-viewing echoendoscope. METHODS Nineteen patients with acute abdominal pain associated with increased liver tests entered the study. Evaluation of the biliary tree was performed by using an oblique-viewing echoendoscope (JF-UM20; Olympus Europe GmbH, Hamburg, Germany). When biliary stones or sludge were found, bile duct cannulation and sphincterotomy were performed in the same session. RESULTS Bile duct stones were diagnosed by EUS in 4 patients and biliary sludge in 12; the subsequent cholangiography and sphincterotomy with stone extraction confirmed the diagnosis in all patients. Bile duct cannulation failed in 1 patient. EUS showed features of chronic pancreatitis in 3 cases. The mean time for the whole procedure (EUS plus endoscopic retrograde cholangiography with biliary treatment) was 27 minutes. No procedure-related complications were observed. CONCLUSION This new approach appears to be feasible and safe, providing an accurate diagnosis and, at the same time, an appropriate treatment of common bile duct stones when needed. With technical improvements, this extended EUS technique could be used as the first-line procedure in patients with biliopancreatic diseases.

Abstract
BACKGROUND Use of magnetic resonance cholangiopancreatography (MRCP) for confirmation of presence of biliary obstruction is virtually risk-free. However, unlike diagnostic endoscopic retrograde cholangiopancreatography (ERCP), no therapeutic option can be offered simultaneously with MRCP. The aim of the study is to assess the cost-effectiveness of MRCP when compared with the conventional practice of diagnostic ERCP for the investigation of biliary obstruction in adults. METHODS Cost-effectiveness analysis from the perspective of the health care provider. Sensitivity analysis includes presentation of a family of cost effectiveness acceptability curves and the impact of different risks of common bile duct stones associated with ultrasound and liver function test results. The main outcome measure is cost per quality adjusted life year (QALY). RESULTS Baseline results, at 37% probability of common bile duct stones, show that MRCP is the dominant strategy, with expected savings of 149 pounds sterling (325 pounds sterling to - 15 pounds sterling) and expected QALY gain of 0.011 (0-0.030) per case. The probability of avoiding unnecessary therapeutic ERCP is 30%. For patients at high risk of common bile duct stones (probability >60%) ERCP is the preferable strategy. CONCLUSIONS The baseline estimate is that MRCP would be both cost saving and would result in improved quality of life outcomes compared to diagnostic ERCP, but its potential sources of economic benefit are highly dependent on access to, and waiting lists for adequate MRI technology at hospital level.

Abstract
Introduction: Endoscopic retrograde cholangiopancreatography (ERCP) has been the premier diagnostic and therapeutic endoscopic procedure in the management of pancreatic and biliary diseases (PBD). The use of endoscopic ultrasound (EUS), including EUS-guided fine needle aspiration (FNA), of pancreatic and biliary tumours has become more widely available in the last decade and has gradually replaced diagnostic ERCP. Together with EUS, other imaging modalities like magnetic resonance cholangiopancreatography (MRCP) have resulted in a decrease in the number of ERCPs. With the advent of interventional EUS, ERCP is at risk of being completely eclipsed.
Methods: A search of all relevant articles on EUS and ERCP from Medline and peer-reviewed journals.
Results: This review article examines the exact place of ERCP and EUS and their relative contributions in the management algorithm of PBD.
Conclusion: Although diagnostic EUS, including EUS-guided FNA, is well established in the evaluation of PBD, interventional EUS is still in its infancy and its true potential is unknown. Therefore, therapeutic ERCP still has a vital, albeit smaller role to play in the treatment of pancreatic and biliary diseases.

Abstract
BACKGROUND Emergency laparoscopic exploration can be used to identify the causative pathology of acute abdominal pain. Laparoscopic surgery also allows treatment of many intraabdominal disorders. This report was prepared to describe the effectiveness of laparoscopic surgery compared to laparotomy or nonoperative treatment. METHODS A panel of European experts in abdominal and gynecological surgery was assembled and participated in a consensus conference using Delphi methods. The aim was to develop evidence-based recommendations for the most common diseases that may cause acute abdominal pain. RECOMMENDATIONS Laparoscopic surgery was found to be clearly superior for patients with a presumable diagnosis of perforated peptic ulcer, acute cholecystitis, appendicitis, or pelvic inflammatory disease. In the emergency setting, laparoscopy is of unclear or limited value if adhesive bowel obstruction, acute diverticulitis, nonbiliary pancreatitis, hernia incarceration, or mesenteric ischemia are suspected. In stable patients with acute abdominal pain, noninvasive diagnostics should be fully exhausted before considering explorative surgery. However, diagnostic laparoscopy may be useful if no diagnosis can be found by conventional diagnostics. More clinical data are needed on the use of laparoscopy after blunt or penetrating trauma of the abdomen. CONCLUSIONS Due to diagnostic and therapeutic advantages, laparoscopic surgery is useful for the majority of conditions underlying acute abdominal pain, but noninvasive diagnostic aids should be exhausted first. Depending on symptom severity, laparoscopy should be advocated if routine diagnostic procedures have failed to yield results.

Abstract
BACKGROUND There is controversy about the optimal method to detect common bile duct (CBD) stones in patients with mild resolving gallstone pancreatitis. The aim of this study was to evaluate magnetic resonance cholangiopancreatography (MRCP) in detecting choledocholithiasis in this group of patients. STUDY DESIGN A prospective randomized trial was conducted. Patients randomized to group 1 (n = 34) underwent laparoscopic cholecystectomy (LC) and intraoperative cholangiography (IOC). Those randomized to group 2 (n = 29) had preoperative MRCP, of these, patients with negative MRCP underwent LC and IOC, patients with positive MRCP had preoperative ERCP followed by LC. RESULTS Sixty-three patients were randomized (34 to group 1 and 29 to group 2). CBD stones were found in 5 patients in group 1. CBD exploration was performed in 2 patients, preoperative ERCP in 1, and postoperative ERCP in the other 2. MRCP showed CBD stones in 4 patients in group 2. There were two false-positive MRCPs. Four patients with a negative MRCP did not have IOC or ERCP, the remaining 21 patients with a negative MRCP had a negative IOC. The MRCP sensitivity was 100% (95% CI, 16-100%), specificity 91% (95% CI, 72-99%), positive predictive value 50% (95% CI, 7-93%), negative predictive value 100% (95% CI, 84-100%), and accuracy 92% (95% CI, 74-99%). CONCLUSIONS Patients with resolving gallstone pancreatitis and a negative MRCP do not need preoperative ERCP or IOC. Only patients with a positive MRCP will require preoperative ERCP.

Abstract
BACKGROUND This study aimed to compare an 18-s fast spin echo magnetic resonance image sequence (coronal thick-section two-dimensional breathhold) with a three-dimensional axial and coronal thin-section sequence and its secondary reconstruction, and to assess its value in the diagnosis of bile duct pathologies, particularly common bile duct stones (CBDS) before laparoscopic cholecystectomy. METHODS This study prospectively included 72 patients. Because of protocol violations, 14 of these patients had to be excluded. Thus, 58 patients (29 Man and 29 women with a mean age of 51 years) who had cholecystolithiasis or suspected choledocholithiasis were evaluated. Magnetic resonance cholangiopancreatography (MRCP) was performed for all patients with a fast sequence (18 s) and a long sequence (coronal oblique and axial respiratory triggered; 16 min). Two radiologists, blinded with respect to diagnosis, evaluated all the radiographic images. The MRCP results were confirmed for all the patients: 20 by endoscopic retrograde cholangiopancreatography, 46 by intraoperative cholangiography, and 2 by percutaneous transhepatic cholangiography. RESULTS According to the findings, 16 patients (28%) had CBDS, 6 patients (10%) had common bile duct stenosis, and 36 patients (62%) had a clear bile duct. With regard to CBDS, the short sequence had 100% specificity, 94% sensitivity, and an overall accuracy of 98%. Its negative predictive value was 98%, and its positive predictive value was 100%. The long sequence had a specificity of 100% and a sensitivity of 100%. CONCLUSION Because of its high sensitivity and specifity, MRCP has the potential to be the diagnostic method of choice for CBD evaluation. The short sequence is not suitable for the diagnosis of all CBD pathologies, but in cases of suspected CBDS, more than 80% of the patients could be diagnosed correctly, and the complete sequence could be dropped.

Abstract
OBJECTIVE Our purpose was to compare the accuracy of MR cholangiopancreatography and endoscopic sonography for the diagnosis of common bile duct stones in patients with a mild to moderate clinical suspicion of common bile duct stones. SUBJECTS AND METHODS Forty-seven patients were prospectively enrolled. Inclusion criteria included acute pancreatitis, subclinical jaundice, and clinical features of common bile duct stone migration. Radial endoscopic sonography and MR cholangiopancreatography with the single-shot fast spin-echo technique were performed a maximum of 48 hr apart. The gold-standard diagnosis was obtained with ERCP (n = 20) or intraoperative cholangiography (n = 14) if the results of endoscopic sonography or MR cholangiopancreatography were abnormal or if a cholecystectomy was performed, or by clinical and biochemical follow-up (n = 11) if the results of endoscopic sonography and MR cholangiopancreatography were normal. RESULTS The final diagnosis was common bile duct stones in 16 patients, malignant obstructions in four, and another biliary disease in two (lithiasis migration aspect with papillary edema); 23 patients had no biliary disease. The sensitivity and specificity of MR cholangiopancreatography were, respectively, 90.5% and 87.5% for etiologic diagnosis and 87.5% and 96.6% for the detection of common bile duct stones. The corresponding values for endoscopic sonography were 86.4% and 91.3% for etiologic diagnosis and 93.8% and 96.6% for visualization of choledocholithiasis. Accuracy did not significantly differ between the techniques. CONCLUSION In cases of mild to moderate suspicion of choledocholithiasis, the accuracies of endoscopic sonography and MR cholangiopancreatography are similar. Because MR cholangiopancreatography is noninvasive, it may be preferred for this indication.

Abstract
Investigations examining the use of magnetic resonance cholangiography (MRC) for the diagnosis of primary sclerosing cholangitis (PSC) have described comparable accuracy when compared to endoscopic retrograde cholangiopancreatography (ERCP). The effectiveness of MRC based on overall cost, however, remains unknown. Our aim was to determine the average cost per correct diagnosis using MRC or ERCP as the initial testing strategy for the diagnosis of PSC. A decision analysis model was constructed employing diagnostic test parameters prospectively determined among 73 patients with clinically suspected biliary disease. ERCP was performed within 24 hours after MRC. Cost data were derived from average Medicare reimbursement fee schedules. The prevalence of PSC in the study cohort was 32%. The sensitivity and specificity of MRC for the diagnosis of PSC were 82% and 98%, respectively. The average cost per correct diagnosis of PSC was 724.00 US dollars for initial MRC (including the cost of ERCP following a negative MRC examination) versus 793.17 US dollars for initial ERCP. In the absence of biliary obstruction, the average cost per correct diagnosis of PSC was 549.64 US dollars with MRC versus 623.25 US dollars or ERCP. The average cost of managing post-ERCP-related complications among patients with PSC was 2902.20 US dollars (range, 1915.40-5031.54 US dollars). For ERCP to be the optimal initial test strategy, a prevalence rate of PSC greater than 45%, MRC specificity less than 85%, or reduction in the average cost per diagnosis to 538.30 US dollars would be required. In conclusion, MRC has comparable accuracy to ERCP and results in cost savings when used as the initial test strategy for diagnosing PSC.

Abstract
OBJECTIVE The role of endoscopic retrograde cholangiopancreatography (ERCP) in mild acute biliary pancreatitis is controversial. This study examined the results of ERCP in patients with predicted mild disease and analysed biochemical and imaging findings in relation to the occurrence of choledocholithiasis. PATIENTS AND METHODS There were 172 consecutive patients, admitted between January 1998 and December 2000, with the diagnosis of acute pancreatitis. All patients were investigated using transcutaneous ultrasonography and ERCP if biliary aetiology was suspected. Serum bilirubin and alkaline phosphatase were measured, together with abdominal ultrasonographic findings, as potential predictors for choledocholithiasis. RESULTS Biliary calculus was the aetiology in 62.8% of patients (108/172). Among these 108 patients, 79.6% (86/108) suffered from mild disease. There were only 80 patients who underwent ERCP, and the incidence of choledocholithiasis was 45% (36/80). Although significant correlation was shown between all three measured parameters (bilirubin, alkaline phosphatase and ultrasonographic abnormalities) and choledocholithiasis, their individual sensitivities, specificities and predictive values were low. Nonetheless, if all three tests were normal, the incidence of ductal stones was significantly lower than that in cases with abnormalities in any one of these parameters (4.8% vs 59.3%). CONCLUSION Routine ERCP is not recommended for patients with mild, acute biliary pancreatitis when there is no biochemical derangement or ultrasonographic evidence of a dilated biliary system.

Abstract
AIM To evaluate the value and safety of endoscopic retrograde cholangiopancreatography (ERCP) and endoscopic treatment in acute biliary pancreatitis.
METHODS Ninety-one patients with acute biliary pancreatitis including 13 patients with severe acute biliary pancreatitis in the ERCP group underwent ERCP and endoscopic therapy. 15 patients with severe acute biliary pancreatitis were not treated by either surgery, endoscopy or early ERCP in the control group. Etiological factors, therapeutic effects and complications were observed in all the patients of the two groups.
RESULTS In ERCP group, ERCP showed biliary tract disease in 56 cases, common bile duct stones in 26, cholecyst stone in 17, microcholelith in 4, cholangitis in 9, larger diverticula around the papilla in 3, papillitis in 5, pancreatic diverticulum in 2, and normal in 25. 46 cases of biliary tract disease were treated by endoscopy including papillosphincterotomy, endoscopic nasal biliary drainage and endoscopic dilatation of the accessory papilla. There were no significant differences in the recovery days of serum amylase back to normal between ERCP group (3.4±1.6 d) and control group (4.5±2.8 d), but the mean days of disappearance of abdominal pain (4.4±2.0 d), fever (5.0±3.4 d), abnormal white blood cell count (6.5±5.4 d) and hospitalization (21.9±8.4 d) were significantly shorter in the ERCP group than in the control group (8.4±6.1 d, 16.1±19.0 d, 19.1±19.3 d, 41.3±20.0 d, P<0.05). Complication rate (53.9%) and mortality rate (0%) in ERCP group were lower than those of control group (80.0%, 23.1% P<0.05). 17 cases had early complication (18.7%) in ERCP group. Of them, biliary tract infection occurred in 2 cases (2.2%), retroperitoneal pneumatosis in 1 case (1.1%), bleeding of digestive tract in 1 case (1.1%), deterioriation of pancreatitis in 13 cases. 15 patients were cured by medication treatment. Operations were performed in one patient. One patient died.
CONCLUSION ERCP and endoscopic therapy are safe and effective for patients with acute pancreatitis.

Abstract
Acute pancreatitis is an inflammation of the pancreas that can, in a minority of patients, lead to local complications, multiorgan failure, and death. Gallstones are the most common cause of acute pancreatitis in Western countries. The majority of patients with acute gallstone pancreatitis have mild disease and recover within 3 to 5 days with bed rest and intravenous fluid replacement. In up to 20% of patients, severe pancreatitis develops and can involve pancreatic tissue necrosis and multiorgan failure. Recent advances in the care of patients with gallstone-induced pancreatitis include better severity stratification on hospital admission, more aggressive fluid resuscitation in the early disease course, early use of antibiotics in patients with pancreatic necrosis, a shift from parenteral to enteral feeding regimens, a better defined and less aggressive approach to pancreatic surgery, and the possibility to remove impacted gallstones endoscopically. Urgent endoscopic retrograde cholangiopancreatography and sphincterotomy are recommended in patients with signs of cholangitis or jaundice, ultrasound evidence of dilated common bile duct, or evidence of severe disease.

Abstract
OBJECTIVES To investigate the diagnostic efficacy of magnetic resonance cholangiopancreatography (MRCP) in choledocholithiasis and to determine whether use of MRCP may eliminate the need for purely diagnostic endoscopic retrograde cholangiopancreatography (ERCP). PATIENTS AND METHODS A total of 116 patients with suspected biliopancreatic pathology were studied prospectively between November 1996 and February 1998. Choledocholithiasis was initially suspected in 61 patients and rated before ERCP and MRCP as being of low, intermediate, or high probability based on clinical, laboratory, and/or imaging findings (Cotton criteria). RESULTS The sensitivity of choledocholithiasis diagnosis was 91%, with a global efficacy of 90%. The level of duct stone obstruction was visualized in all patients. Suprastenotic dilatation also showed a good correlation to ERCP. Choledocholithiasis was found in 32 patients (65%) and 3 patients (33%) in the high- and intermediate-probability groups, respectively. None of the low-probability patients had choledocholithiasis. Endoscopic retrograde cholangiopancreatography was performed for only a diagnostic (not therapeutic) purpose in 3 patients (6%) and 2 patients (22%) of the high- and intermediate-probability cases, respectively. CONCLUSIONS Magnetic resonance cholangiopancreatography seems to be effective in diagnosing choledocholithiasis. It plays a fundamental role in patients with a low or intermediate risk of choledocholithiasis, contributing to the avoidance of purely diagnostic ERCP.

Abstract
Medical decisions often depend, in part, on cost-effectiveness concerns. Decision analysis is frequently used to help resolve these questions. Unfortunately, this technique has received little attention in neurosurgery. Using an example of moderate head injury, the authors illustrate the utility of this powerful tool in estimating the cost effectiveness of neurosurgical management options.
