[PMID: 37712446 DOI: 10.1080/00365521.2023.2257825] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/17/2023] [Revised: 09/05/2023] [Accepted: 09/05/2023] [Indexed: 09/16/2023]
Abstract
BACKGROUNDS AND AIMS Magnetic resonance cholangiopancreatography (MRCP) plays a significant role in diagnosing common bile duct stones (CBDS). Currently, there are no studies to detect CBDS by using the deep learning (DL) model in MRCP. This study aimed to use the DL model You Only Look Once version 5 (YOLOv5) to diagnose CBDS in MRCP images and verify its validity compared to the accuracy of radiologists. METHODS By collecting the thick-slab MRCP images of patients diagnosed with CBDS, 4 submodels of YOLOv5 were used to train and validate the performance. Precision, recall rate, and mean average precision (mAP) were used to evaluate model performance. Analyze possible reasons that may affect detection accuracy by validating MRCP images in 63 CBDS patients and comparing them with radiologist detection accuracy. Calculate the correctness of YOLOv5 for detecting one CBDS and multiple CBDS separately. RESULTS The precision of YOLOv5l (0.970) was higher than that of YOLOv5x (0.909), YOLOv5m (0.874), and YOLOv5s (0.939). The mAP did not differ significantly between the 4 submodels, with the following results: YOLOv5l (0.942), YOLOv5x (0.947), YOLO5s (0.927), and YOLOv5m (0.946). However, in terms of training time, YOLOv5s was the fastest (4.8 h), detecting CBDS in only 7.2 milliseconds per image. In 63 patients the YOLOv5l model detected CBDS with an accuracy of 90.5% compared to 92.1% for radiologists, analyzing the difference between the positive group successfully identified and the unidentified negative group not. The incorporated variables include common bile duct diameter > 1 cm (p = .560), combined gallbladder stones (p = .706), maximum stone diameter (p = .057), combined cholangitis (p = .846), and combined pancreatitis (p = .656), and the number of CBDS (p = .415). When only one CBDS was present, the accuracy rate reached 94%. When multiple CBDSs were present, the recognition rate dropped to 70%. CONCLUSION YOLOv5l is the model with the best results and is almost as accurate as the radiologist's detection of CBDS and is also capable of detecting the number of CBDS. Although the accuracy of the test gradually decreases as the number of stones increases, it can still be useful for the clinician's initial diagnosis.

Abstract
Introduction Accurate diagnosis and prompt definitive management of choledocholithiasis are vital in acute gallstone pancreatitis. The sensitivity of detection of choledocholithiasis varies across imaging modalities. Magnetic resonance cholangiopancreatography (MRCP) is the most sensitive but may not be necessary, resulting in both delayed definitive management and increased costs. We aimed to evaluate the range of radiological investigations patients with acute gallstone pancreatitis underwent and the clinical appropriateness of MRCP when performed. Methods This was an observational study of patients diagnosed with acute gallstone pancreatitis between January 1, 2019 and November 30, 2021 in a district general hospital in London, UK. A detailed review of patient records, laboratory and radiological results, and endoscopic and/or operative intervention was undertaken. Results One hundred consecutive patients diagnosed with acute gallstone pancreatitis (median age 57 years) were included. Seventy-nine had a transabdominal ultrasound (USS), 46 had CT, and 40 patients had MRCP. The median waiting time for these investigations was 1, 0, and 4 days, respectively. Choledocholithiasis was identified in 21 patients (4 on USS, 5 on CT, and 12 on MRCP). As definitive management, 37% underwent endoscopic retrograde cholangiopancreatography, and 57% underwent laparoscopic cholecystectomy. A total of 19% of patients were readmitted with pancreatitis prior to definitive management. Conclusions First-line imaging investigations such as USS and CT can detect some cases of choledocholithiasis in patients with acute gallstone pancreatitis, but not all. Despite expenses in terms of cost and length of hospital stay, MRCP remains an essential resource to detect cases of choledocholithiasis not captured by USS or CT. We recommend establishing a guideline to streamline imaging in assessing acute gallstone pancreatitis.

Abstract
BACKGROUND In preparing the Japanese (JPN) guidelines for the management of acute pancreatitis 2021, the committee focused the issues raised by the results of nationwide epidemiological survey in 2016 in Japan METHOD: In addition to a systematic search using the previous JPN guidelines, papers published from January 2014 to September 2019 were searched for the contents to be covered by the guidelines based on the concept of GRADE system. RESULTS Thirty-six clinical questions (CQ) were prepared in 15 subject areas. Base on the facts that patients diagnosed with severe disease by both Japanese prognostic factor score and contrast-enhanced CT grade had a high fatality rate and that little prognosis improvement after 2 weeks of disease onset was not obtained, we emphasized the importance of Pancreatitis Bundles, which was shown to be effective in improving prognosis, and the CQ sections for local pancreatic complications had been expanded to ensure adoption of a step-up approach. Furthermore, on the facts that enteral nutrition for severe acute pancreatitis was not started early within 48 hours of admission and that unnecessary prophylactic antibiotics was used in almost all cases, we emphasized early enteral nutrition in small amounts even if gastric feeding is used and no prophylactic antibiotics in mild pancreatitis. CONCLUSION All the members of the committee have put a lot of effort into preparing the extensively revised guidelines in the hope that more people will have a common understanding and that better medical care will be spread.

Abstract
BACKGROUND AND AIM Magnetic resonance cholangiopancreatography (MRCP) can accurately diagnose common bile duct (CBD) stones but is laborious to interpret. We developed an artificial neural network (ANN) capable of automatically assisting physicians with the diagnosis of CBD stones. This study aimed to evaluate the ANN's diagnostic performance for detecting CBD stones in thick-slab MRCP images and identify clinical factors predictive of accurate diagnosis. METHODS The presence of CBD stones was confirmed via direct visualization through endoscopic retrograde cholangiopancreatography (ERCP). The absence of CBD stones was confirmed by either a negative endoscopic ultrasound accompanied by clinical improvements or negative findings on ERCP. Our base networks were constructed using state-of-the-art EfficientNet-B5 neural network models, which are widely used for image classification. RESULTS In total, 3156 images were collected from 789 patients. Of these, 2628 images from 657 patients were used for training. An additional 1924 images from 481 patients were prospectively collected for validation. Across the entire prospective validation cohort, the ANN achieved a sensitivity, specificity, positive predictive value, negative predictive value, and overall accuracy of 93.03%, 97.05%, 97.01%, 93.12%, and 95.01%, respectively. Similarly, a radiologist achieved a sensitivity, specificity, positive predictive value, negative predictive value, and overall accuracy 91.16%, 93.25%, 93.22%, 90.20%, and 91.68%, respectively. In multivariate analysis, only bile duct diameter > 10 mm (odds ratio = 2.45, 95% confidence interval [1.08-6.07], P = 0.040) was related to ANN diagnostic accuracy. CONCLUSION Our ANN algorithm automatically and quickly diagnoses CBD stones in thick-slab MRCP images, therein aiding physicians with optimizing clinical practice, such as whether to perform ERCP.

Abstract
Acute pancreatitis is one of the most common reasons for gastroenterology-related hospitalization in the United States. With significant morbidity and subsequent mortality related to both the acute presentation and subsequent sequelae, prompt diagnosis and appropriate management are critical, especially in the first 24 hours of illness. It is also important to accurately recognize complications, such as pancreatic fluid collections and vascular events, and identify a definitive cause so that a strategy to prevent future attacks can be implemented.

Abstract
BACKGROUND Around 10% to 30% patients with acute pancreatitis (AP) do not have a cause after the routine investigations, and are considered as having idiopathic acute pancreatitis (IAP). Establishing the etiology in such patients will prevent recurrences and evolution to chronic pancreatitis. Endoscopic ultrasonography (EUS) and magnetic resonance cholangiopancreatography (MRCP) characteristically are used to diagnose IAP when routine methods fail, but their exact role is not determined. METHODS This prospective study was undertaken in a tertiary care hospital, in which patients admitted initially with diagnosis of IAP were evaluated. These patients underwent MRCP and EUS at least 4 weeks after an attack of AP. The results of EUS and MRCP were compared and analyzed with various clinical variables using suitable statistical tests. RESULTS A total of 31 patients with IAP were included. EUS and/or MRCP was able to establish at least one etiology in 17 patients (54.8%). The diagnoses revealed were gallbladder (GB) microlithiasis, GB sludge, choledocholithiasis, pancreatobiliary ductal anomalies, pancreatic adenocarcinoma, and intraductal papillary mucinous neoplasm. Comparing the diagnostic accuracy of both the modalities, EUS (14/31) was able to diagnose more cases than MRCP (8/31). The diagnostic capability of EUS was lower in patients who had a cholecystectomy (12.5% vs. 56.5%; p = 0.03). CONCLUSIONS EUS and MRCP are useful modalities in the etiological diagnosis of IAP and should be used in conjunction. EUS is better for establishing a possible biliary etiology and MRCP for an anatomical alteration in pancreatobiliary ducts.

Abstract
Acute pancreatitis, a common cause of hospitalization in the United States, is often the result of biliary tract disease. In 2016, the American Gastroenterological Association released a guideline that addresses the practical considerations in managing acute pancreatitis within the first 72 hours after the patient presents. The guideline specifically recommends goal-directed hydration therapy, early enteral feeding, judicious use of endoscopic retrograde cholangiopancreatography (ERCP), and gallbladder surgery during the index admission for patients with mild pancreatitis. The authors discuss their approach to these interventions in the context of a patient with recurrent acute pancreatitis who chooses to delay surgery until after hospital discharge. They address hydration and timing of surgery, as well as how they would manage the patient's preferences in the face of existing guidelines.

Abstract
BACKGROUND Choledocholithiasis is present in up to 15% of cholecystectomy patients. Treatment can be surgical, endoscopic, or via interventional radiology. We hypothesized significant heterogeneity between hospitals exists in the approach to suspected common duct stones. METHODS A retrospective review of patients that had a preoperative MRCP, endoscopic ultrasound, endoscopic retrograde cholangiopancreatogram (ERCP), or intra-operative cholangiogram was performed. Comparisons were by Wilcoxon-Mann-Whitney tests with significance of p < 0.05 for paired variables and p < 0.017 for multiple comparisons. RESULTS Twelve participating institutions identified 1263 patients (409 men and 854 women) with a median age of 49 years (IQR: 31-94). Liver function tests (LFT's) were elevated in 939 patients (75%), median bilirubin level 1.75 mg/dl (IQ: 0.8-3.7 mg/dl) and median common duct size 7 mm (IQR 5-10 mm). The most common initial procedure was cholecystectomy with IOC at seven institutions, endoscopy at four and MRCP at one. CONCLUSION Significant variation exists within the surgical community regarding suspected common duct stones. These results underscore the need for a protocol for common duct stones to minimize multiple, redundant interventions.

Abstract
OBJECTIVES This study aims to evaluate the diagnostic value of magnetic resonance cholangiopancreatography (MRCP) in detecting common bile duct (CBD) stones in acute biliary pancreatitis (ABP). METHODS The medical records of patients presenting with ABP from January 2008 to July 2013 were reviewed to assess the value of MRCP in detecting CBD stones in ABP. Endoscopic retrograde cholangiopancreatography (ERCP) was used as the reference standard to assess the diagnostic yield of MRCP in detecting choledocholithiasis. When ERCP was unavailable, intraoperative cholangiography or clinical follow-up was used as the reference standard. RESULTS Seventy-eight patients who underwent MRCP were diagnosed with ABP, and thirty of the 78 patients (38%) were confirmed to have CBD stones per the study protocol. The sensitivity of MRCP in detecting CBD stones in ABP was 93.3% compared to 66.7% for abdominal CT (P < 0.008). The overall accuracy of MRCP in detecting choledocholithiasis was 85.9% compared to 74.0% for abdominal CT (P < 0.041). The area under the receiver operating characteristic curve (AUC) of MRCP in detecting CBD stones was 0.882, which was more accurate than the AUC of 0.727 for abdominal CT (P = 0.039). In 38 patients who underwent ERCP, the sensitivity and negative predictive value of MRCP in detecting CBD stones were both 100% regardless of the dilatation of the bile duct (≥7 mm versus < 7 mm). CONCLUSION MRCP is an effective, noninvasive modality to detect CBD stones in ABP and can help identify patients who require ERCP.

Abstract
Acute recurrent pancreatitis (ARP) is defined as more than two attacks of acute pancreatitis with complete or almost complete resolution of symptoms and signs of pancreatitis between episodes. The initial evaluation fails to detect the cause of ARP in 10%–30% of patients, whose condition is classified as idiopathic ARP. Endoscopic ultrasound (EUS) has gained increasing attention as a useful imaging modality for the pancreas and the extrahepatic biliary tree. The close proximity of the pancreas to the digestive tract allows EUS to obtain detailed images of this organ. This review aims to record pancreaticobiliary endoscopic ultrasound (EUS) and other imaging modalities in the clinical management of patients with idiopathic ARP.

[PMID: 27000127 DOI: 10.1007/s11605-016-3078-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/02/2015] [Accepted: 01/10/2016] [Indexed: 01/31/2023]
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
Acute pancreatitis is an inflammatory condition caused by intracellular activation
and extravasation of inappropriate proteolytic enzymes determining destruction of
pancreatic parenchyma and peripancreatic tissues. This is a fairly common clinical
condition with two main presentations, namely, endematous pancreatitis - a less
severe presentation -, and necrotizing pancreatitis - the most severe presentation
that affects a significant part of patients. The radiological evaluation,
particularly by computed tomography, plays a fundamental role in the definition of
the management of severe cases, especially regarding the characterization of local
complications with implications in the prognosis and in the definition of the
therapeutic approach. New concepts include the subdivision of necrotizing
pancreatitis into the following presentations: pancreatic parenchymal necrosis with
concomitant peripancreatic tissue necrosis, and necrosis restricted to peripancreatic
tissues. Moreover, there was a systematization of the terms acute peripancreatic
fluid collection, pseudocyst, post-necrotic pancreatic/peripancreatic fluid
collections and walled-off pancreatic necrosis. The knowledge about such terms is
extremely relevant to standardize the terminology utilized by specialists involved in
the diagnosis and treatment of these patients.

Abstract
BACKGROUND Endoscopic ultrasound (EUS) and magnetic resonance cholangiopancreatography (MRCP) are tests used in the diagnosis of common bile duct stones in patients suspected of having common bile duct stones prior to undergoing invasive treatment. There has been no systematic review of the accuracy of EUS and MRCP in the diagnosis of common bile duct stones using appropriate reference standards. OBJECTIVES To determine and compare the accuracy of EUS and MRCP for the diagnosis of common bile duct stones. SEARCH METHODS We searched MEDLINE, EMBASE, Science Citation Index Expanded, BIOSIS, and Clinicaltrials.gov until September 2012. We searched the references of included studies to identify further studies and of systematic reviews identified from various databases (Database of Abstracts of Reviews of Effects (DARE), Health Technology Assessment (HTA), Medion, and ARIF (Aggressive Research Intelligence Facility)). We did not restrict studies based on language or publication status, or whether data were collected prospectively or retrospectively. SELECTION CRITERIA We included studies that provided the number of true positives, false positives, false negatives, and true negatives for EUS or MRCP. We only accepted studies that confirmed the presence of common bile duct stones by extraction of the stones (irrespective of whether this was done by surgical or endoscopic methods) for a positive test, and absence of common bile duct stones by surgical or endoscopic negative exploration of the common bile duct or symptom free follow-up for at least six months for a negative test, as the reference standard in people suspected of having common bile duct stones. We included participants with or without prior diagnosis of cholelithiasis; with or without symptoms and complications of common bile duct stones, with or without prior treatment for common bile duct stones; and before or after cholecystectomy. At least two authors independently screened abstracts and selected studies for inclusion. DATA COLLECTION AND ANALYSIS Two authors independently collected the data from each study. We used the bivariate model to obtain pooled estimates of sensitivity and specificity. MAIN RESULTS We included a total of 18 studies involving 2366 participants (976 participants with common bile duct stones and 1390 participants without common bile duct stones). Eleven studies evaluated EUS alone, and five studies evaluated MRCP alone. Two studies evaluated both tests. Most studies included patients who were suspected of having common bile duct stones based on abnormal liver function tests; abnormal transabdominal ultrasound; symptoms such as obstructive jaundice, cholangitis, or pancreatitis; or a combination of the above. The proportion of participants who had undergone cholecystectomy varied across studies. Not one of the studies was of high methodological quality. For EUS, the sensitivities ranged between 0.75 and 1.00 and the specificities ranged between 0.85 and 1.00. The summary sensitivity (95% confidence interval (CI)) and specificity (95% CI) of the 13 studies that evaluated EUS (1537 participants; 686 cases and 851 participants without common bile duct stones) were 0.95 (95% CI 0.91 to 0.97) and 0.97 (95% CI 0.94 to 0.99). For MRCP, the sensitivities ranged between 0.77 and 1.00 and the specificities ranged between 0.73 and 0.99. The summary sensitivity and specificity of the seven studies that evaluated MRCP (996 participants; 361 cases and 635 participants without common bile duct stones) were 0.93 (95% CI 0.87 to 0.96) and 0.96 (95% CI 0.90 to 0.98). There was no evidence of a difference in sensitivity or specificity between EUS and MRCP (P value = 0.5). From the included studies, at the median pre-test probability of common bile duct stones of 41% the post-test probabilities (with 95% CI) associated with positive and negative EUS test results were 0.96 (95% CI 0.92 to 0.98) and 0.03 (95% CI 0.02 to 0.06). At the same pre-test probability, the post-test probabilities associated with positive and negative MRCP test results were 0.94 (95% CI 0.87 to 0.97) and 0.05 (95% CI 0.03 to 0.09). AUTHORS' CONCLUSIONS Both EUS and MRCP have high diagnostic accuracy for detection of common bile duct stones. People with positive EUS or MRCP should undergo endoscopic or surgical extraction of common bile duct stones and those with negative EUS or MRCP do not need further invasive tests. However, if the symptoms persist, further investigations will be indicated. The two tests are similar in terms of diagnostic accuracy and the choice of which test to use will be informed by availability and contra-indications to each test. However, it should be noted that the results are based on studies of poor methodological quality and so the results should be interpreted with caution. Further studies that are of high methodological quality are necessary to determine the diagnostic accuracy of EUS and MRCP for the diagnosis of common bile duct stones.

Abstract
PURPOSE Studies to date have not investigated whether body mass index (BMI) affects the sensitivity and specificity of magnetic resonance cholangiopancreatography (MRCP). The purpose of this study was to investigate the effect of BMI and also concomitant pancreatitis, cholecystitis and cholelithiasis on the sensitivity and specificity of MRCP. MATERIALS AND METHODS Between January 2004 and December 2011, 185 patients were included in the study and divided into 3 groups according to BMI as normal, overweight or obese. Both MRCP and endoscopic retrograde cholangiopancreatography (ERCP) were performed in all patients. ERCP was accepted as the "gold standard." The accuracy, sensitivity and specificity values of the 3 groups were calculated to determine any effects on the results of the MRCP. RESULTS Before separating into groups according to BMI, the statistical results for MRCP in the detection of stone disease were as follows: specificity 74.3%, sensitivity 81.7% and accuracy 79%. After dividing the patients into 3 groups according to BMI, the specificity of stone detection with MRCP in the normal-weight group was 93.8% but decreased to 65.5% in the overweight group and to 72% in the obese group. The sensitivity of stone detection with MRCP in the normal-weight group was 85.2% but decreased to 75% in the overweight group and increased to 88.9% in the obese group. The accuracy was 88.3% in the normal-weight group but decreased to 71.6% in the overweight group and to 81.9% in the obese group. CONCLUSION Our study showed that MRCP performance was decreased in the overweight and obese groups.

Abstract
Background The aim of this study was to evaluate the diagnostic potential of magnetic resonance cholangiopancreatography (MRCP) in preoperative patients with secondary common bile duct stones during the application of laparoscopic trans-cystic common bile duct exploration (LTCBDE). Material/Methods The clinical records of 255 patients were retrospectively analyzed. All patients included in the study were examined by MRCP 3 days prior to LTCBDE. Results Secondary bile duct stones were detected in 220 patients using LTCBDE. Of the patients diagnosed by MRCP, 141 were true-positive, 28 were true-negative, 7 were false-positive and 79 were false-negative. The sensitivity, specificity, accuracy, positive predictive value, and negative predictive value of MRCP for secondary common bile duct stones were 64.09%, 80.00%, 66.27%, 95.27%, and 26.17%, respectively. When the cases with muddy stones were excluded, the outcomes were 80.41%, 79.41%, 69.23%, 94.44%, and 48.21%, respectively. When cases with stones <3 mm (inclusive) in diameter were excluded, the outcomes were 93.75%, 79.41%, 86.27%, 93.75%, and 65.85%, respectively. When cases with stones <5 mm (inclusive) in diameter were excluded, the outcomes were 93.10%, 79.41%, 89.26%, 92.05%, and 81.82%, respectively. Conclusions The effectiveness of preoperative MRCP is overestimated for the diagnosis of secondary common bile duct stones, particularly for muddy and micro-stones.

Abstract
INTRODUCTION The aim of this study was to identify whether magnetic resonance cholangiopancreatography (MRCP) can be used selectively in patients with acute gallstone pancreatitis to detect choledocholithiasis, based on liver function tests (LFTs) and ultrasonography appearance. METHODS All patients admitted between January 2008 and January 2011 with gallstone pancreatitis (amylase >300u/l) who underwent MRCP were included in the study. LFTs and radiology reports were obtained from the respective computer systems. RESULTS Overall, 173 patients with acute gallstone pancreatitis underwent MRCP and 30% (52/173) showed choledocholithiasis. The mean bilirubin level was significantly higher in those with choledocholithiasis (46 ±5μmol/l vs 36 ±3μmol/l, p=0.0388) although there was no significant difference in alkaline phosphatase (276 ±25iu/l vs 229 ±16iu/l, p=0.1154). However, sensitivity of abnormal bilirubin (>21μmol/l) for choledocholithiasis was only 62% and specificity was 41%. Sensitivity of abnormal alkaline phosphatase (>140iu/l) for choledocholithiasis was only 75% and specificity was 37%. There was a significant association between biliary dilatation on ultrasonography and choledocholithiasis on MRCP (p=0.0099) although the sensitivity of biliary dilatation for choledocholithiasis was only 44% and the specificity was 79%. Furthermore, there was no difference in the incidence of choledocholithiasis on MRCP for those patients with persistently deranged LFTs versus those whose LFTs returned to normal (relative risk: 1.07, 95% confidence interval: 0.61-1.89, p=1.00). Overall, 10% of patients with choledocholithiasis on MRCP had entirely normal LFTs on admission and no biliary dilatation or choledocholithiasis on ultrasonography. CONCLUSIONS All patients with acute gallstone pancreatitis should undergo specific imaging, preferably MRCP, to exclude choledocholithiasis as LFTs and ultrasonography are inaccurate in predicting common bile duct stones.

Abstract
Acute pancreatitis is the most common gastro-intestinal indication for acute hospitalization and its incidence continues to rise. In severe pancreatitis, morbidity and mortality remains high and is mainly driven by organ failure and infectious complications. Early management strategies should aim to prevent or treat organ failure and to reduce infectious complications. This review addresses the management of acute pancreatitis in the first hours to days after onset of symptoms, including fluid therapy, nutrition and endoscopic retrograde cholangiography. This review also discusses the recently revised Atlanta classification which provides new uniform terminology, thereby facilitating communication regarding severity and complications of pancreatitis.

Abstract
OBJECTIVE To determine the prevalence of biliopancreatic reflux (BPR) in patients with biliary pancreatitis (BP) undergoing elective cholecystectomy with intraoperative cholangiography (IOC) in comparison with a control group of symptomatic cholelithiasis (CG). PATIENTS AND METHODS Retrospective review of 107 consecutive BP cases. BPR was determined by IOC and liver function tests (LFT) were recorded at admission (A), 48hours, and preoperative examination (P). LFT analysis between A and P were analysed between groups with respect to BPR, time interval to cholecystectomy within the same group and by determination of observed value/maximum normal value ratio (OV/MNV). RESULTS BPR incidence was 38.3% in BP in comparison with 5% in CG (p=0.0001) it was independent from interval time to cholecystectomy, in contrast with Odditis, suggesting an anatomical condition for CCBP and a functional one for Odditis. LFT analysis showed no differences in relation to BPR incidence. LFT excluding AP and GGT returned to normal values with significant differences in OV/MNV when BPR was present which points to an increased cholestasis in BPR group. US dilatation of CBD was noted in 10.3% and was associated to CCBP. CONCLUSIONS BPR in BP increases cholestasis and contributes to confusion in the estimation of common bile duct stones increasing ERCP-EE rates. US and biochemical markers of CBDS show a low specificity due to BPR-CCBP which suggests that MRI-cholangiography is a mandatory exploration before ERCP-EE examination.

Abstract
BACKGROUND The role and timing of endoscopic retrograde cholangiopancreatography (ERCP) in acute gallstone pancreatitis remains controversial. A number of clinical trials and meta-analyses have provided conflicting evidence. OBJECTIVES To systematically review evidence from randomized controlled trials (RCTs) assessing the clinical effectiveness and safety of the early routine ERCP strategy compared to the early conservative management with or without selective use of ERCP strategy, based on all important, clinically relevant and standardized outcomes including mortality, local and systemic complications as defined by the Atlanta Classification (Bradley 1993) and by authors of the primary study, and ERCP-related complications in unselected patients with acute gallstone pancreatitis. SEARCH METHODS We searched the CENTRAL (The Cochrane Library), MEDLINE, EMBASE, and LILACS databases and major conference proceedings up to January 2012, using the Cochrane Upper Gastrointestinal and Pancreatic Diseases model with no language restrictions. SELECTION CRITERIA RCTs comparing the early routine ERCP strategy versus the early conservative management with or without selective use of ERCP strategy in patients with suspected acute gallstone pancreatitis. We included studies in which the population with acute gallstone pancreatitis was a subgroup within a larger group of patients. We only included studies involving only a selected subgroup of patients with acute gallstone pancreatitis (actual severe pancreatitis) in subgroup analyses. DATA COLLECTION AND ANALYSIS Two review authors conducted study selection, data extraction, and methodological quality assessment independently. Using intention-to-treat analysis with random-effects models, we combined dichotomous data to obtain risk ratios (RR) with 95% confidence intervals (CI). We assessed heterogeneity using the Chi² test and I² statistic. To explore sources of heterogeneity, we conducted a priori subgroup analyses according to predicted severity of pancreatitis, cholangitis, biliary obstruction, time to ERCP in routine ERCP strategy, use of selective ERCP in conservative management strategy, and risk of bias. To assess the robustness of our results, we carried out sensitivity analyses using different summary statistics (RR versus odds ratio (OR)) and meta-analytic models (fixed versus random-effects), and per-protocol analysis. We performed influence analysis by exclusion of each study. MAIN RESULTS Five RCTs comprising 644 participants were included in the main analyses. Two additional RCTs, comprising only patients with actual severe acute gallstone pancreatitis, were included only in subgroup analyses. There was statistical heterogeneity among trials for mortality, but not for other outcomes. In unselected patients with acute gallstone pancreatitis, there were no statistically significant differences between the two strategies in mortality (RR 0.74, 95% CI 0.18 to 3.03), local and systemic complications as defined by the Atlanta Classification (RR 0.86, 95% CI 0.52 to 1.43; and RR 0.59, 95% CI 0.31 to 1.11 respectively) and by authors of the primary study (RR 0.80, 95% CI 0.51 to 1.26; and RR 0.76, 95% CI 0.53 to 1.09 respectively). The results were robust to sensitivity and influence analyses except for systemic complications as defined by the Atlanta Classification. There was no evidence to suggest that the results were dependent on predicted severity of pancreatitis. Among trials that included patients with cholangitis, the early routine ERCP strategy significantly reduced mortality (RR 0.20, 95% CI 0.06 to 0.68), local and systemic complications as defined by the Atlanta Classification (RR 0.45, 95% CI 0.20 to 0.99; and RR 0.37, 95% CI 0.18 to 0.78 respectively) and by authors of the primary study (RR 0.50, 95% CI 0.29 to 0.87; and RR 0.41, 95% CI 0.21 to 0.82 respectively). Among trials that included patients with biliary obstruction, the early routine ERCP strategy was associated with a significant reduction in local complications as defined by authors of the primary study (RR 0.54, 95% CI 0.32 to 0.91), and a non-significant trend towards reduction of local and systemic complications as defined by the Atlanta Classification (RR 0.53, 95% CI 0.26 to 1.07; and RR 0.56, 95% CI 0.30 to 1.02 respectively) and systemic complications as defined by authors of the primary study (RR 0.59, 95% CI 0.35 to 1.01). ERCP complications were infrequent. AUTHORS' CONCLUSIONS In patients with acute gallstone pancreatitis, there is no evidence that early routine ERCP significantly affects mortality, and local or systemic complications of pancreatitis, regardless of predicted severity. Our results, however, provide support for current recommendations that early ERCP should be considered in patients with co-existing cholangitis or biliary obstruction.

Santos JS, Kemp R, Ardengh JC, Elias J. Conservative management of cholestasis with and without fever in acute biliary pancreatitis. World J Gastrointest Surg 2012; 4:55-61.

Abstract
The presence of cholestasis in both mild and severe forms of acute biliary pancreatitis (ABP) does not justify, of itself, early endoscopic retrograde cholangiography (ERC) or endoscopic sphincterotomy (ES). Clinical support treatment of acute pancreatitis for one to two weeks is usually accompanied by regression of pancreatic edema, of cholestasis and by stone migration to the duodenum in 60%-88% of cases. On the other hand, in cases with both cholestasis and fever, a condition usually characterized as ABP associated with cholangitis, early ES is normally indicated. However, in daily clinical practice, it is practically impossible to guarantee the coexistence of cholangitis and mild or severe acute pancreatitis. Pain, fever and cholestasis, as well as mental confusion and hypotension, may be attributed to inflammatory and necrotic events related to ABP. Under these circumstances, evaluation of the bile duct by endo-ultrasonography (EUS) or magnetic resonance cholangiography (MRC) before performing ERC and ES seems reasonable. Thus, it is necessary to assess the effects of the association between early and opportune access to the treatment of local and systemic inflammatory/infectious effects of ABP with cholestasis and fever, and to characterize the possible scenarios and the subsequent approaches to the common bile duct, directed by less invasive examinations such as MRC or EUS.

Abstract
BACKGROUND AND AIM Conventional radiological methods, including transcutaneous ultrasonography (US), computed tomography (CT), and magnetic resonance cholangiopancreatography (MRCP) are non-invasive and recommended for the detection of etiologies of acute biliary pancreatitis (ABP). There are still, however, a number of patients whose etiologies cannot be found by these methods. The value of endoscopic ultrasound (EUS) for this population is still unknown. The aim of the present study was to evaluate the role of EUS in exploring the unknown etiology of mild ABP. METHODS The data from patients with mild ABP admitted to Changhai Hospital, Shanghai, China, from June 2006 to December 2009 were retrospectively collected, and the results of the imaging methods in detecting biliary disorders were analyzed. RESULTS A total of 223 patients with mild ABP underwent both US and CT. Of these, 106 underwent additional MRCP. There were still 37 patients with unknown biliary etiologies, even after the use of the conventional methods mentioned earlier. EUS was conducted in 33 of these patients. Abnormalities associated with the etiology of mild ABP were found in 14 cases (42.4%) confirmed by subsequent endoscopic retrograde cholangiopancreatography, with biliary stones in 11 cases, biliary sludge in two cases, and ampullary adenocarcinoma in one case. CONCLUSION The results suggest that EUS is helpful in the identification of the etiology of mild biliary pancreatitis when conventional radiological imaging is negative or equivocal.

Abstract
BACKGROUND/AIMS Endoscopic ultrasonography (EUS) is a useful modality to diagnose causes of pancreatitis. The role of EUS for prediction of pancreatitis severity has not been studied. The aim of this study was to identify the utility of EUS in determining the severity of acute pancreatitis (AP). METHODS All patients diagnosed with pancreatitis consecutively underwent EUS on the 2nd day of their admission. Atlanta criteria were used as the severity index of pancreatitis. RESULTS During the study period, 114 patients (74 females, 40 males; mean age of 53.03 ± 17.7 years) were enrolled in the study. The most common cause of AP was gallstone (78.9%). According to the Atlanta criteria, pancreatitis was mild in 72 (63.2%) and severe in 42 (36.8%) patients. In univariate analysis, the presence of peripancreatic edema, pancreas inhomogeneity, common bile duct dilation and ascites were associated with severe pancreatitis. In multivariate analysis, only the presence of peripancreatic edema in EUS correlated with the severity of AP according to the Atlanta criteria (sensitivity, specificity and accuracy: 65.8, 75.7 and 72.2%, respectively). CONCLUSION EUS may be a new useful imaging modality for prediction of severity of AP and may have prognostic significance in the early phase of AP. and IAP.

Abstract
BACKGROUND Gallstone pancreatitis is a consequence of ampullary obstruction by common bile duct (CBD) calculi. Magnetic resonance cholangiopancreatography (MRCP) has been advocated for routine use to diagnose choledocholithiasis. However, the selective use of MRCP in clinically equivocal situations has not been explored until now. This study examines the diagnostic value of selective MRCP in gallstone pancreatitis. METHODS We conducted a retrospective audit of all presentations of gallstone pancreatitis between January 2001 and December 2007 at Middlemore Hospital, Auckland, New Zealand. Demographic data, clinical presentation, biochemical and radiological findings and outcomes were reviewed. RESULTS There were 339 cases of gallstone pancreatitis during the study period; 236 patients were women and the mean age was 52 years. Overall, choledocholithiasis was diagnosed in 95 patients. A total of 117 patients underwent MRCP within a median of 4 days of admission, with 15 (13.7%) showing choledocholithiasis. There was no significant difference in time to MRCP between positive and negative groups. Endoscopic retrograde cholangiopancreatography (ERCP)/intraoperative cholangiography (IOC) confirmed 13 of 15 stones within a median of 2.5 days. However, MRCP missed 8 cases of choledocholithiasis subsequently demonstrated on ERCP/IOC, where clinical suspicion remained after a negative MRCP. Its sensitivity was 62% and specificity 98%. The positive likelihood ratio was 6.5 and the negative likelihood ratio was 0.1. In all, 222 patients followed different clinical pathways with 82 CBD stones diagnosed by ERCP/IOC. CONCLUSION Selective MRCP is highly specific in gallstone pancreatitis but may not be sensitive enough to exclude choledocholithiasis in this context.

Abstract
Establishing a biliary etiology in acute pancreatitis is clinically important because of the potential need for invasive treatment, such as endoscopic retrograde cholangiopancreatography. The etiology of acute biliary pancreatitis (ABP) is multifactorial and complex. Passage of small gallbladder stones or biliary sludge through the ampulla of Vater seems to be important in the pathogenesis of ABP. Other factors, such as anatomical variations associated with an increased biliopancreatic reflux, bile and pancreatic juice exclusion from the duodenum, and genetic factors might contribute to the development of ABP. A diagnosis of a biliary etiology in acute pancreatitis is supported by both laboratory and imaging investigations. An increased serum level of alanine aminotransferase (>1.0 microkat/l) is associated with a high probability of gallstone pancreatitis (positive predictive value 80-90%). Confirmation of choledocholithiasis is most accurately obtained using endoscopic ultrasonography or magnetic resonance cholangiopancreatography. This Review discusses the pathogenesis of ABP and the clinical techniques used to predict and establish a biliary origin in patients with suspected ABP.

Abstract
OBJECTIVE To analyze influence of pre-operative MRCP on the management of patients with gall stones. PATIENTS & METHODS This prospective randomized study was carried on 250 patients who underwent laparoscopic cholecystectomy within 3 years. In group I, pre-operative MRCP was performed in 125 patients with age range of 18-62 years. Group II included 125 patients managed by laparoscopic cholecystectomy without doing pre-operative MRCP with age range of 21-65 years. RESULTS In group I; pre-operative MRCP screening revealed clinically silent CBD stones in 5 patients (4%), accessory cystic duct in 2 (1.6%), abnormal insertion of cystic duct in 1 (0.8%). Postoperatively, bile duct injury was inflected in 1 patient in group I. On the other hand, there were 2 patients with bile duct injury and 5 patients with residual stones in group II. There was a statistically significant increase of post-operative complications in group II (p <or= 0.5). CONCLUSIONS MRCP is diagnostically useful in management of patients with gall stones prior to laparoscopic cholecystectomy and its routine use can reduce the incidence of post-operative complications.

Abstract
Acute pancreatitis is a common disease most frequently caused by gallstone disease or excess alcohol ingestion. Diagnosis is usually based on characteristic symptoms, often in conjunction with elevated serum pancreatic enzymes. Imaging is not always necessary, but may be performed for many reasons, such as to confirm a diagnosis of pancreatitis, rule out other causes of abdominal pain, elucidate the cause of pancreatitis, or to evaluate for complications such as necrosis or pseudocysts. Though the majority of patients will have mild, self-limiting disease, some will develop severe disease associated with organ failure. These patients are at risk to develop complications from ongoing pancreatic inflammation such as pancreatic necrosis, fluid collections, pseudocysts, and pancreatic duct disruption. Validated scoring systems can help predict the severity of pancreatitis, and thus, guide monitoring and intervention.Treatment of acute pancreatitis involves supportive care with fluid replacement, pain control, and controlled initiation of regular food intake. Prophylactic antibiotics are not recommended in acute pancreatitis if there is no evidence of pancreatic infection. In patients who fail to improve, further evaluation is necessary to assess for complications that require intervention such as pseudocysts or pancreatic necrosis. Endoscopy, including ERCP and EUS, and/or cholecystectomy may be indicated in the appropriate clinical setting. Ultimately, the management of the patient with severe acute pancreatitis will require a multidisciplinary approach.

Abstract
The detection and management of bile duct stones in acute pancreatitis have improved considerably. Now it is possible to identify non-invasively stones in the duct before definitive treatment. Recently new evidence has confirmed that the indication for early endoscopic sphincterotomy should be severe acute pancreatitis with evidence of bile duct obstruction. This review analyses the evidence that defines current best practice in this area. and IAP.

Abstract
Practical guidelines for the diagnosis of acute pancreatitis are presented so that a rapid and adequate diagnosis can be made. When acute pancreatitis is suspected in patients with acute onset of abdominal pain and tenderness mainly in the upper abdomen, the diagnosis of acute pancreatitis is made on the basis of elevated levels of pancreatic enzymes in the blood and/or urine. Furthermore, other acute abdominal diseases are ruled out if local findings associated with pancreatitis are confirmed by diagnostic imaging. According to the diagnostic criteria established in Japan, patients who present with two of the following three manifestations are diagnosed as having acute pancreatitis: characteristic upper abdominal pain, elevated levels of pancreatic enzymes, and findings of ultrasonography (US), CT or MRI suggesting acute pancreatitis. Detection of elevated levels of blood pancreatic enzymes is crucial in the diagnosis of acute pancreatitis. Measurement of blood lipase is recommended, because it is reported to be superior to all other pancreatic enzymes in terms of sensitivity and specificity. For measurements of the blood amylase level widely used in Japan, it should be cautioned that, because of its low specificity, abnormal high values are also often obtained in diseases other than pancreatitis. The cut-off level of blood pancreatic enzymes for the diagnosis of acute pancreatitis is not able to be set because of lack of sufficient evidence and consensus to date. CT study is the most appropriate procedure to confirm image findings of acute pancreatitis. Elucidation of the etiology of acute pancreatitis should be continued after a diagnosis of acute pancreatitis. In the process of the etiologic elucidation of acute pancreatitis, judgment whether it is gallstone-induced or not is most urgent and crucial for deciding treatment policy including the assessment of whether endoscopic papillary treatment should be conducted or not. The diagnosis of gallstone-induced acute pancreatitis can be made by combining detection of elevated levels of bilirubin, transamylase (ALT, AST) and ALP detected by hematological examination and the visualization of gallstones by US.

Abstract
Gallstones are the commonest cause of acute pancreatitis (AP), a potentially life-threatening condition, worldwide. The pathogenesis of acute pancreatitis has not been fully understood. Laboratory and radiological investigations are critical for diagnosis as well prognosis prediction. Scoring systems based on radiological findings and serologic inflammatory markers have been proposed as better predictors of disease severity. Early endoscopic retrograde cholangiopancreatography (ERCP) is beneficial in a group of patients with gallstone pancreatitis. Laparoscopic cholecystectomy with preoperative endoscopic common bile duct clearance is recommended as a treatment of choice for acute biliary pancreatitis. The timing of cholecystectomy, following ERCP, for biliary pancreatitis can vary markedly depending on the severity of pancreatitis.

Abstract
PURPOSE The influence of treatment access regulation and technological resources on the mortality profile of acute biliary pancreatitis (ABP) was evaluated. METHODS The cases seen in a tertiary hospital were studied during two periods of time: 1995-1999 and 2000-2004, i.e., before and after the implementation of medical regulation. RESULTS Among the 727 patients with acute pancreatitis, 267 had ABP and were classified according to APACHE II scores. The cases being referred to the tertiary hospital decreased from 441 to 286 (p < 0.001). The patients' profile regarding age, gender, severity, cholestasis incidence and mortality were similar during the first and second periods of study (n = 154 and n = 113, respectively). The number of patients with hematocrit > or =44% was smaller during the second study period (p<0.002). The use of magnetic resonance cholangiography, videolaparoscopic cholecystectomy, and access to the ICU were found to be more frequent during the second study period. Regarding the deaths occurring within 14 days of hospitalisation, 73.4% and 81.3% were observed during the first and second study periods, respectively. CONCLUSION Since the improvement in clinical and technological approach was not enough to modify the mortality profile of ABP, further studies on the treatment of inflammatory responses should be carried out.

Abstract
The presenting pattern and natural progression of biochemical markers of biliary tract obstruction in patients with gallstone pancreatitis have not been elucidated. We analyzed serial values of bilirubin levels following admission to discharge in 143 patients. Ninety-four of patients demonstrated a Decrescendo (falling) pattern of bilirubin levels from admission until normalization at 21 hours (median). Forty-nine patients demonstrated a Crescendo-Decrescendo (initially rising) pattern with peak levels of bilirubin occurring at 39 hours after admission followed by a subsequent normalization after a median of 119 hours. Patients in the Decrescendo group were significantly younger (33 versus 41 years, P = .02) and more patients had experienced symptoms for greater than 48 hours (65% versus 47%, P = .05). Ten percent of patients in the Decrescendo group and 29% of patients in the Crescendo-Decrescendo group underwent ERCP (P = .02). Normalization of biochemical markers after ERCP was significantly delayed in both groups compared to no ERCP. Older patients present earlier, with higher bilirubin levels and normalize slower than younger patients, perhaps due to fibrosis of the ampulla and decreased compliance of the common bile duct. Patients who disobstruct spontaneously (90%) normalize quicker than patients undergoing ERCP.

Abstract
BACKGROUND Recurrent attacks of acute biliary pancreatitis (RABP) are prevented by (laparoscopic) cholecystectomy. Since the introduction of endoscopic retrograde cholangiopancreaticography (ERCP), several series have described a similar reduction of RABP after endoscopic sphincterotomy (ES). This report discusses the different treatment options for preventing RABP including conservative treatment, cholecystectomy, ES, and combinations of these options as well as their respective timing. METHODS A search in PubMed for observational studies and clinical (comparative) trials published in the English language was performed on the subject of recurrent acute biliary pancreatitis and other gallstone complications after an initial attack of acute pancreatitis. RESULT Cholecystectomy and ES both are superior to conservative treatment in reducing the incidence of RABP. Cholecystectomy provides additional protection for gallstone-related complications and mortality. Observational studies indicate that cholecystectomy combined with ES is the most effective treatment for reducing the incidence of RABP attacks. CONCLUSION From the literature data it can be concluded that ES is as effective in reducing RABP as cholecystectomy but inferior in reducing mortality and overall morbidity. The combination of ES and cholecystectomy seems superior to either of the treatment methods alone. A prospective randomized clinical trial comparing ES plus cholecystectomy with cholecystectomy alone is needed.

Abstract
Acute pancreatitis is one of the more commonly encountered etiologies in the emergency setting. While in the majority of cases it is a self-limiting disease which responds rapidly to conservative management, in some cases acute pancreatitis may present with a more pronounced, sometimes dramatic, clinical picture and requires immediate medical care to avoid fatal complication. In this context, imaging plays a significant role because it enables identification of the development of the disease and local/systemic complications. The purpose of this article is to offer an overview of the disease and a spectrum of imaging findings in patients with acute pancreatitis, emphasizing the role of ultrasound, computed tomography, and magnetic resonance imaging according to the appropriate clinical context and advantages and limitations of each imaging modality are examined.

Abstract
BACKGROUND Whether all patients undergoing cholecystectomy following an episode of biliary pancreatitis require direct common bile duct evaluation is controversial. We hypothesized such evaluation can be omitted safely among select patients at low risk for choledocholithiasis. METHODS One hundred forty-eight patients undergoing cholecystectomy for biliary pancreatitis (January 1995-December 2005) met the following inclusion criteria: (1) no preoperative endoscopic retrograde cholangiography (ERC) or endoscopic retrograde cholangiopancreatography (ERCP); (2) normal or decreasing liver function tests (LFTs) preoperatively; and (3) no ductal dilation on non-invasive preoperative imaging. Group I had intraoperative cholangiography (IOC, n = 27); group II did not (n = 121). RESULTS No differences between groups I and II were evident in postoperative retained-stone related events: recurrent pancreatitis (11% vs 8%, P = .7), cholangitis (0% in both groups), and asymptomatic LFT elevation (0% vs 3%, P > .99). CONCLUSIONS Direct ductal evaluation can be omitted safely in select patients undergoing cholecystectomy for biliary pancreatitis who are at low risk for choledocholithiasis.

Abstract
Several clinical and methodologic difficulties occur when diagnosing acute pancreatitis in the pediatric age group. Due to its uncommonness and heterogeneous symptoms, acute pancreatitis in children is often misdiagnosed, and prospective studies are lacking. Guidelines for classifying, diagnosing, and managing acute pancreatitis are frequently based on standards that are developed and validated in adult patients. Among the broad range of etiologies of pediatric acute pancreatitis in children, gallstones and biliary disease may play a greater role than previously believed. Although it is typically a benign disease in the pediatric population, complications such as pseudocysts may occur. When there are fatalities, they are usually attributed to systemic illness rather than the pancreatitis itself. Improvements in diagnostic and imaging methods and growing awareness cannot account for the recent increases in the observed incidence of pediatric acute pancreatitis.

Abstract
BACKGROUND Early endoscopic retrograde cholangiopancreatography (ERCP) should be performed in all patients with acute biliary pancreatitis (ABP) and coexisting acute cholangitis. In patients without cholangitis and predicted mild ABP it is generally accepted that early ERCP should not be performed. Nevertheless, there is a controversy regarding the role of early ERCP in the treatment of patients with predicted severe ABP without cholangitis. We reviewed randomized trials on early ERCP versus conservative management in patients with ABP without acute cholangitis. METHODS Relevant publications in 3 electronic databases (MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials) were systematically reviewed and meta-analyzed. RESULTS Seven randomized trials on ERCP in acute pancreatitis were found, of which 3 including a total of 450 patients (230 in the invasive arm and 220 in the control arm) qualified for a meta-analysis according to predefined criteria. In all patients with ABP (predicted mild and severe), early ERCP was associated with a nonsignificant reduction in overall complications [risk ratio (RR) 0.76; 95% confidence interval (CI) 0.41-1.04; P = 0.38] and a nonsignificant increase in mortality (RR 1.13; 95% CI 0.23-5.63; P = 0.88). Subgroup analysis based on predicted severity did not affect these outcomes (overall complications: predicted mild: RR 0.86; 95% CI 0.62-1.19; P = 0.36; predicted severe: RR 0.82; 95% CI 0.32-2.10; P = 0.68; mortality: predicted mild: RR 1.90; 95% CI 0.25-14.55; P = 0.53; predicted severe: RR 1.28; 95% CI 0.20-8.06; P = 0.80). CONCLUSION In this meta-analysis, early ERCP in patients with predicted mild and predicted severe ABP without acute cholangitis did not lead to a significant reduction in the risk of overall complications and mortality.

Abstract
OBJECTIVE Evaluate endoscopic retrograde cholangiopancreatography (ERCP) in general hospitals in France. METHODS Prospective study of ERCP procedures performed in 28 centers during an 18-month period. Success was assessed at day 1; morbidity and mortality were assessed at 30 days. RESULTS 2708 ERCP procedures were performed in 28 centers. The rate of success was 92.1% and was higher among centers performing more than 200 procedures annually (OR 2.07 [1.522.86]). Therapeutic success was correlated with diameter of the common bile duct>6 mm (OR 9.1 [7.15-11.57]) and center activity level (OR 1.91 [1.38-2.6]). The rate of complications and deaths were 9.1% and 4%; procedure-specific mortality was 0.8%. Morbidity was lower in centers performing more than 200 procedures annually (OR 0.36 [0.22-0.6]) and when the operator considered the procedure easy to perform (OR 0.5 [0.35-0.74]). Mortality was correlated with ASA score (OR for patients with ASA scores 2, 3, 4 were 9 [1-66], 53.3 [7.3-392] and 164.7 [21.71249]) respectively, occurrence of a complication (OR=3.9 [1.96-7.78]), diameter of the common bile duct, and technical success (OR=0.49 [0.27-0.88]). CONCLUSION This study shows that success of ERCP and post-ERCP morbidity are related to center activity level while post-ERCP mortality is strongly linked with the patient's ASA score.

Abstract
BACKGROUND Acute pancreatitis in pregnancy is rare. We report our institutional therapeutic approaches to this disease and its effect on maternal and fetal outcomes. METHODS A retrospective review of medical records of pregnant women admitted to Brigham and Women's Hospital between 1996 and 2006. RESULTS Twenty-one patients, presenting with 34 episodes of acute pancreatitis were identified. Most attacks (56%) occurred in the second trimester. Twelve patients had biliary pancreatitis. Three had pancreatitis secondary to other causes and six had "undetermined" etiologies. Of those with biliary pancreatitis, six underwent cholecystectomy; in a third of these cases, initial conservative therapy had failed. The other six patients underwent endoscopic sphincterotomy (n=2) or conservative therapy (n=4). Fifty percent of the patients with biliary pancreatitis managed conservatively had a recurrent episode of pancreatitis vs none in the cholecystectomy group. There was no significant difference in length of hospital stay between the three treatment groups (cholecystectomy, sphincterotomy, and conservative therapy). No maternal deaths were observed; there were four preterm labors and one fetal loss. CONCLUSION If treated conservatively, pregnant patients with biliary pancreatitis appear to have a high recurrence rate. Early surgical intervention is appropriate, safe, and does not increase the length of hospital stay.
