Diagnostics (Basel) 2023; 13:3256. [PMID: 37892077 PMCID: PMC10606009 DOI: 10.3390/diagnostics13203256] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/19/2023] [Revised: 09/24/2023] [Accepted: 10/17/2023] [Indexed: 10/29/2023] Open
Abstract
Idiopathic acute pancreatitis (IAP) presents a diagnostic challenge and refers to cases where the cause of acute pancreatitis remains uncertain despite a comprehensive diagnostic evaluation. Endoscopic ultrasound (EUS) has emerged as a valuable tool in the diagnostic workup of IAP. This review explores the pivotal role of EUS in detecting the actual cause of IAP and assessing its accuracy, timing, safety, and future technological improvement. In this review, we investigate the role of EUS in identifying the actual cause of IAP by examining the available literature. We aim to assess possible existing evidence regarding EUS accuracy, timing, and safety and explore potential trends of future technological improvements in EUS for diagnostic purposes. Following PRISMA guidelines, 60 pertinent studies were selected and analysed. EUS emerges as a crucial diagnostic tool, particularly when conventional imaging fails. It can offer intricate visualization of the pancreas, biliary system, and adjacent structures. Microlithiasis, biliary sludge, chronic pancreatitis, and small pancreatic tumors seem to be much more accurately identified with EUS in the setting of IAP. The optimal timing for EUS is post-resolution of the acute phase of the disease. With a low rate of complications, EUS poses minimal safety concerns. EUS-guided interventions, including fine-needle aspiration, collection drainage, and biopsies, aid in the cytological analysis. With high diagnostic accuracy, safety, and therapeutic potential, EUS is able to improve patient outcomes when managing IAP. Further refinement of EUS techniques and cost-effectiveness assessment of EUS-guided approaches need to be explored in multicentre prospective studies. This review underscores EUS as a transformative tool in unraveling IAP's enigma and advancing diagnostic and therapeutic strategies.

Abstract
INTRODUCTION Endoscopic ultrasound (EUS) provides high-resolution images of both pancreatic parenchyma and duct and therefore is an integral component of evaluating and treating patients with pancreatitis and its complications. The development of enhanced EUS imaging techniques and newer EUS-specific accessories has expanded the diagnostic and therapeutic role of EUS in patients with acute and chronic pancreatitis (CP). AREAS COVERED This review discusses the current diagnostic and therapeutic role of EUS in acute pancreatitis (AP), CP, and autoimmune pancreatitis (AIP). EXPERT OPINION EUS plays a vital role in patients with AP by confirming the presence of common bile duct (CBD) stones in patients with acute biliary pancreatitis and intermediate probability of CBD stones. It plays an important role in the etiological evaluation of patients with idiopathic acute and recurrent pancreatitis. EUS is also an essential modality for diagnosing and managing pancreatico-biliary as well as gastroduodenal complications associated with CP. EUS-guided FNB using newer generation core biopsy needles has made possible accurate diagnosis of AIP by providing tissue samples with preserved architecture.

Mazza S, Elvo B, Conti CB, Drago A, Verga MC, Soro S, De Silvestri A, Cereatti F, Grassia R. Endoscopic ultrasound diagnostic gain over computed tomography and magnetic resonance cholang iopancreatography in defining etiology of idiopathic acute pancreatitis. World J Gastrointest Endosc 2022; 14:376-386. [DOI: 10.4253/wjge.v14.i6.376] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/28/2022] [Revised: 04/23/2022] [Accepted: 05/23/2022] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND About 10%-30% of acute pancreatitis remain idiopathic (IAP) even after clinical and imaging tests, including abdominal ultrasound (US), contrast-enhanced computed tomography (CECT) and magnetic resonance cholangiopancreatography (MRCP). This is a relevant issue, as up to 20% of patients with IAP have recurrent episodes and 26% of them develop chronic pancreatitis. Few data are available on the role of EUS in clarifying the etiology of IAP after failure of one or more cross-sectional techniques.
AIM To evaluate the diagnostic gain after failure of one or more previous cross-sectional exams.
METHODS We retrospectively collected data about consecutive patients with AP and at least one negative test between US, CECT and MRCP, who underwent linear EUS between January 2017 and December 2020. We investigated the EUS diagnostic yield and the EUS diagnostic gain over different combinations of these cross-sectional imaging techniques for the etiologic diagnosis of AP. Types and frequency of EUS diagnosis were also analyzed, and EUS diagnosis was compared with the clinical parameters. After EUS, patients were followed-up for a median of 31.5 mo to detect cases of pancreatitis recurrence.
RESULTS We enrolled 81 patients (63% males, mean age 61 ± 18, 23% with previous cholecystectomy, 17% with recurrent pancreatitis). Overall EUS diagnostic yield for AP etiological diagnosis was 79% (20% lithiasis, 31% acute on chronic pancreatitis, 14% pancreatic solid or cystic lesions, 5% pancreas divisum, 5% autoimmune pancreatitis, 5% ductal abnormalities), while 21% remained idiopathic. US, CECT and MRCP, taken alone or in combination, led to AP etiological diagnosis in 16 (20%) patients; among the remaining 65 patients, 49 (75%) obtained a diagnosis at EUS, with an overall EUS diagnostic gain of 61%. Sixty-eight patients had negative US; among them, EUS allowed etiological diagnosis in 59 (87%). Sixty-three patients had a negative CECT; among them, 47 (74%) obtained diagnosis with EUS. Twenty-four had a negative MRCP; among them, 20 (83%) had EUS diagnosis. Twenty-one had negative CT + MRCP, of which 17 (81%) had EUS diagnosis, with a EUS diagnostic gain of 63%. Patients with biliary etiology and without previous cholecystectomy had higher median values of alanine aminotransferase (154 vs 25, P = 0.010), aspartate aminotransferase (95 vs 29, P = 0.018), direct bilirubin (1.2 vs 0.6, P = 0.015), gamma-glutamyl transpeptidase (180 vs 48, P = 0.006) and alkaline phosphatase (150 vs 72, P = 0.015) Chronic pancreatitis diagnosis was more frequent in patients with recurrent pancreatitis at baseline (82% vs 21%, P < 0.001). During the follow-up, AP recurred in 3 patients, one of which remained idiopathic.
CONCLUSION EUS is a good test to define AP etiology. It showed a 63% diagnostic gain over CECT + MRCP. In suitable patients, EUS should always be performed in cases of IAP. Further prospective studies are needed.

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
BACKGROUND Idiopathic acute pancreatitis (IAP) has a 25 % pancreatitis recurrence rate. Endoscopic ultrasonography (EUS) may diagnose treatable causes of IAP and hence prevent recurrence. The goal of this systematic review with meta-analysis is to determine the diagnostic yield of EUS and its impact on recurrence. METHODS PubMed, EMBASE and the Cochrane Library were systematically searched for English studies on EUS in adults with IAP. The primary outcome was diagnostic yield. Secondary outcomes included recurrence. Methodological quality was assessed using the QUADAS-2 score. Meta-analysis was performed to calculate the pooled diagnostic yield and risk ratio with 95 % confidence intervals (CI) using a random-effects model with inverse variance method. RESULTS 22 studies were included, with 1490 IAP patients who underwent EUS. Overall diagnostic yield was 59 % (874 /1490; 95 %CI 52 % - 66 %). The most common etiologies were biliary (429 /1490; 30 %, 95 %CI 21 % - 41 %) and chronic pancreatitis (271 /1490; 12 %, 95 %CI 8 % - 19 %). In 2 % of patients, neoplasms were detected (45 /1490; 95 %CI 1 % - 4 %). There was no difference in yield between patients with or without recurrent IAP before EUS (risk ratio 0.89, 95 %CI 0.71 - 1.11). CONCLUSIONS EUS is able to identify a potential etiology in the majority of patients with IAP, detecting mostly biliary origin or chronic pancreatitis, but also neoplasms in 2 % of patients. EUS may be associated with a reduction of recurrence rate. Future studies should include complete diagnostic work-up and preferably include patients with a first episode of IAP only.

Abstract
INTRODUCTION Idiopathic acute pancreatitis (IAP) remains a dilemma for physicians as it is uncertain whether patients with IAP may actually have an occult aetiology. It is unclear to what extent additional diagnostic modalities such as endoscopic ultrasonography (EUS) are warranted after a first episode of IAP in order to uncover this aetiology. Failure to timely determine treatable aetiologies delays appropriate treatment and might subsequently cause recurrence of acute pancreatitis. Therefore, the aim of the Pancreatitis of Idiopathic origin: Clinical added value of endoscopic UltraSonography (PICUS) Study is to determine the value of routine EUS in determining the aetiology of pancreatitis in patients with a first episode of IAP. METHODS AND ANALYSIS PICUS is designed as a multicentre prospective cohort study of 106 patients with a first episode of IAP after complete standard diagnostic work-up, in whom a diagnostic EUS will be performed. Standard diagnostic work-up will include a complete personal and family history, laboratory tests including serum alanine aminotransferase, calcium and triglyceride levels and imaging by transabdominal ultrasound, magnetic resonance imaging or magnetic resonance cholangiopancreaticography after clinical recovery from the acute pancreatitis episode. The primary outcome measure is detection of aetiology by EUS. Secondary outcome measures include pancreatitis recurrence rate, severity of recurrent pancreatitis, readmission, additional interventions, complications, length of hospital stay, quality of life, mortality and costs, during a follow-up period of 12 months. ETHICS AND DISSEMINATION PICUS is conducted according to the Declaration of Helsinki and Guideline for Good Clinical Practice. Five medical ethics review committees assessed PICUS (Medical Ethics Review Committee of Academic Medical Center, University Medical Center Utrecht, Radboud University Medical Center, Erasmus Medical Center and Maastricht University Medical Center). The results will be submitted for publication in an international peer-reviewed journal. TRIAL REGISTRATION NUMBER Netherlands Trial Registry (NL7066). Prospectively registered.

Abstract
BACKGROUND Acute pancreatitis (AP) is one of the most common general acute surgical presentations. Current recommendations are that idiopathic acute pancreatitis (IAP) should account for no more than 20% of AP cases. Some studies suggest gallbladder microlithiasis is the aetiology in up to 75% of IAP patients. Endoscopic ultrasound (EUS) has been reported to be effective in the detection of microlithiasis and choledocholithiasis as well as pancreatic parenchymal, ductal and ampullary disorders. The aims of this study were to evaluate the usefulness of EUS in establishing aetiology in IAP patients and to assess if there is a role for EUS in the selection criteria for laparoscopic cholecystectomy to treat a potential biliary cause in IAP patients. METHODS A systematic review following PRISMA guideline was performed to gather data on patients with IAP undergoing EUS for further investigation. Three databases (MEDLINE, PubMed, and EMBASE) were searched to 28 July 2018. RESULTS Our systematic review included 28 studies, comprising 1850 patients with an initial diagnosis of IAP prior to having EUS. Diagnosis of a potential aetiology or associated pancreatic pathology was established in 1095 (62%, p < 0.001) of cases. A biliary aetiology (microlithiasis or choledocholithiasis) was found in 37%. Chronic pancreatitis and associated pancreatic findings (dilated pancreatic duct, pancreatic duct stricture or stone) were found in 21%. Pancreatic neoplasms were found in 6%. Of the patients who had identifiable biliary pathology on EUS that proceeded to cholecystectomy, 2% had a recurrence of AP during a mean follow-up period of 20.5 months. CONCLUSIONS There is a likely role for the routine use of EUS in the assessment of patients with IAP. The routine use of EUS may decrease the proportion of cases with a diagnosis of IAP. EUS may provide better selection criteria for laparoscopic cholecystectomy in patients with an initial diagnosis of IAP.

Abstract
OBJECTIVES Endoscopic ultrasound (EUS) is a minimally invasive pancreatic imaging modality. We evaluated children with idiopathic acute pancreatitis (IAP) and acute recurrent pancreatitis (ARP) for changes of chronicity (Rosemont criteria) and biliary risk factors. Diagnostic yield of simultaneously performed transabdominal ultrasonography (TUS) was compared with EUS. METHODS This was a prospective observational study. Patients underwent EUS and TUS after 2 months of pancreatitis attack. RESULTS Forty-five (18 IAP, 27 ARP) patients underwent EUS and TUS. Mean (standard deviation) age and weight were 9.1 (2.6) years and 32.66 (12.43) kg in IAP, whereas these were 12.2 (3.1) years and 44.84 (15.12) kg in ARP, respectively. Endoscopic ultrasound demonstrated morphological abnormality in 33.3% and 40.7% of IAP and ARP, respectively (P = 0.61), whereas 16.6% and 25.9% were abnormal in TUS. Endoscopic ultrasound showed unequivocal changes of chronicity (11.1% vs 0%) and risk factors only among ARP (25.9% vs 0%; P = 0.03) and demonstrated slightly higher odds ratio (95% confidence interval) as compared with TUS to detect abnormalities in both IAP (2.43 [0.49-14.17], P = 0.28) and ARP (1.94 [0.60-6.47], P = 0.26). CONCLUSIONS Applying EUS, changes of chronicity and risk factors were noted only in ARP. Endoscopic ultrasound performed better than TUS in detecting chronicity.

Abstract
BACKGROUND AND AIMS Idiopathic acute pancreatitis (IAP) poses a diagnostic challenge for gastroenterologists, because confirmation of the disease etiology has important implications for the selection of the best possible treatment and the prevention of possible recurrence or the development of chronic pancreatitis (CP). ERCP, EUS, and MRCP typically are used to diagnose IAP when conventional radiologic methods fail. However, their exact role in the diagnosis of IAP has not yet been determined. METHODS We searched the PubMed, EMBASE, OVID, Cochrane Library (including CENTRAL), China National Knowledge Infrastructure (CNKI), and Wanfang databases from inception to April 2017. Studies involving the use of EUS and/or MRCP for the etiologic diagnosis of IAP were included. A meta-analysis was performed by using Review Manager Version 5.2 for comparative studies and R software 3.3.3 to determine diagnostic yield of the studies. RESULTS Among the 34 studies that met the inclusion criteria (n = 2338), 7 studies used a combination of EUS and MRCP and totaled 249 patients. The results comparing EUS with MRCP showed a diagnostic yield of 153 of the 239 patients (64%) in the EUS group, which was higher than the yield of 82 of 238 patients (34%) in the MRCP group (P < .001) in the 7 studies, and the diagnostic yield was 60% in the EUS group, 24% in the MRCP group, and 43% in the MRCP after secretin stimulation (S-MRCP) group. In our subgroup analysis of CP and biliary disease, EUS was superior to MRCP (P < .001), but when comparing the efficacy of the modalities in the diagnosis of pancreatic divisum, S-MRCP was obviously superior to MRCP and EUS (12% vs 2% vs 2%). CONCLUSION EUS and MRCP should both be used in the diagnostic work-up of IAP as complementary techniques. EUS had a higher diagnostic accuracy than MRCP (64% vs 34%) in the etiologic diagnosis of IAP and should be preferred for establishing a possible biliary disease and CP diagnosis, whereas S-MRCP was superior to EUS and MRCP in diagnosing a possible anatomic alteration in the biliopancreatic duct system, such as pancreatic divisum.

Abstract
Recurrent acute pancreatitis (RAP) is defined based on the occurrence of two or more episodes of acute pancreatitis. The initial evaluation fails to detect the cause of RAP in 10%-30% of patients, whose condition is classified as idiopathic RAP (IRAP). Idiopathic acute pancreatitis (IAP) is a diagnostic challenge for gastroenterologists. In view of associated morbidity and mortality, it is important to determine the aetiology of pancreatitis to provide early treatment and prevent recurrence. Endoscopic ultrasound (EUS) is an investigation of choice for imaging of pancreas and biliary tract. In view of high diagnostic accuracy and safety of EUS, a EUS based management strategy appears to be a reasonable approach for evaluation of patients with a single/recurrent idiopathic pancreatitis. The most common diagnoses by EUS in IAP is biliary tract disease. The present review aims to discuss the role of EUS in the clinical management and diagnosis of patients with IAP. It elaborates the diagnostic approach to IAP in relation to EUS and other different modalities. Controversial issues in IAP like when to perform EUS, whether to perform after first episode or recurrent episodes, comparison among different investigations and the latest evidence significance are detailed.

Abstract
Magnetic resonance cholangiopancreatography (MRCP), MRCP after secretin stimulation (S-MRCP) and endoscopic ultrasonography (EUS) are all selected to diagnose pancreas divisum. However, the accuracies of three diagnosis remain unclear. The aim is to address the diagnostic accuracies of MRCP, S-MRCP and EUS on pancreas divisum. We searched PubMed, MEDLINE and EMBASE databases from inception to January, 2015. Of the 536 citations retrieved, 16 studies were included. For MRCP diagnosis on pancreas divisum, the area under the hierarchical summary receiver-operating characteristic (HSROC) curve was 0.90 (95% confidence interval [CI] 0.87 to 0.92), and for S-MRCP and EUS, 0.99 (95% CI 0.97 to 0.99) and 0.97 (95% CI 0.96 to 0.98). Sensitivity and specificity for MRCP were 0.59 (95% CI 0.45 to 0.71) and 0.99 (95% CI 0.96 to 1.00); for S-MRCP, 0.83 (95% CI 0.66 to 0.92) and 0.99 (95% CI 0.96 to 1.00); for EUS, 0.85 (95% CI 0.67 to 0.94) and 0.97 (95% CI 0.90 to 0.99). Comprehensive comparison of three diagnostic techniques to pancreas divisum, S-MRCP was more reliable than MRCP and EUS on the effect of the diagnostic test.

Abstract
The application of endoscopic ultrasound (EUS) in children is growing, with studies demonstrating a positive impact of EUS in the management of childhood diseases. EUS has shown to be useful in the evaluation and management of a spectrum of childhood diseases including pancreaticobiliary disease, congenital anomalies, submuocsal lesions, biliary stones disease, inflammatory bowel disease, and eosinophilic esophagitis. Its diagnostic capabilities with fine-needle aspiration and core-needle biopsy are shown to be technically successful, safe, and effective in several pediatric studies. Therapeutic EUS procedures include endoscopic cystgastrostomy, celiac plexus neurolysis, and biliary access. This article discusses the role of EUS for diagnostic and therapeutic purposes in pediatrics.

Abstract
BACKGROUND Japanese (JPN) guidelines for the management of acute pancreatitis were published in 2006. The severity assessment criteria for acute pancreatitis were later revised by the Japanese Ministry of Health, Labour and Welfare (MHLW) in 2008, leading to their publication as the JPN Guidelines 2010. Following the 2012 revision of the Atlanta Classifications of Acute Pancreatitis, in which the classifications of regional complications of pancreatitis were revised, the development of a minimally invasive method for local complications of pancreatitis spread, and emerging evidence was gathered and revised into the JPN Guidelines. METHODS A comprehensive evaluation was carried out on the evidence for epidemiology, diagnosis, severity, treatment, post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis and clinical indicators, based on the concepts of the GRADE system (Grading of Recommendations Assessment, Development and Evaluation). With the graded recommendations, where the evidence was unclear, Meta-Analysis team for JPN Guidelines 2015 conducted an additional new meta-analysis, the results of which were included in the guidelines. RESULTS Thirty-nine questions were prepared in 17 subject areas, for which 43 recommendations were made. The 17 subject areas were: Diagnosis, Diagnostic imaging, Etiology, Severity assessment, Transfer indication, Fluid therapy, Nasogastric tube, Pain control, Antibiotics prophylaxis, Protease inhibitor, Nutritional support, Intensive care, management of Biliary Pancreatitis, management of Abdominal Compartment Syndrome, Interventions for the local complications, Post-ERCP pancreatitis and Clinical Indicator (Pancreatitis Bundles 2015). Meta-analysis was conducted in the following four subject areas based on randomized controlled trials: (1) prophylactic antibiotics use; (2) prophylactic pancreatic stent placement for the prevention of post-ERCP pancreatitis; (3) prophylactic non-steroidal anti-inflammatory drugs (NSAIDs) for the prevention of post-ERCP pancreatitis; and (4) peritoneal lavage. Using the results of the meta-analysis, recommendations were graded to create useful information. In addition, a mobile application was developed, which made it possible to diagnose, assess severity and check pancreatitis bundles. CONCLUSIONS The JPN Guidelines 2015 were prepared using the most up-to-date methods, and including the latest recommended medical treatments, and we are confident that this will make them easy for many clinicians to use, and will provide a useful tool in the decision-making process for the treatment of patients, and optimal medical support. The free mobile application and calculator for the JPN Guidelines 2015 is available via http://www.jshbps.jp/en/guideline/jpn-guideline2015.html.

Abstract
BACKGROUND/AIMS Acute pancreatitis (AP) evades an etiological diagnosis in up to 10 % to 30 % of patients. This group, ie. idiopathic acute pancreatitis (IAP) is prone to a high recurrence (up to 70 %). Endoscopic ultrasound (EUS) is promising, but there is limited data on elucidating the cause of IAP, from India. This observational study was designed to study the role of EUS after the first episode of IAP. METHODS All patients diagnosed to have first episode of IAP were included in the study and taken up for EUS examination after 6 weeks. Patients with conditions known to predispose or precipitate AP, like alcohol binge, drugs, metabolic or autoimmune conditions, or even a positive family history, were excluded from the study. RESULT A total of 51 patients were included. EUS positivity was found in 29 (56.9 %) patients. It included common bile duct (CBD) calculus in 5 (9.8 %), CBD sludge in 4 (7.8 %), gallbladder calculus in 2 (3.9 %), gallbladder sludge in 2 (3.9 %), and chronic pancreatitis (CP) in 16 (31.4 %) patients. Fourteen patients had a normal study and eight patients had indeterminate CP. CONCLUSIONS EUS is safe and has a reasonable diagnostic yield in patients with first episode of IAP. CP and biliary lithiasis are the most frequent positive findings on EUS. EUS should be included in the diagnostic protocol after the first episode of IAP, rather than waiting for recurrent episodes.

Abstract
AIM To define a therapeutic program for mild-moderate acute pancreatitis (AP), often recurrent, which at the end of the diagnostic process remains of undefined etiology. MATERIAL AND METHODS In the period 2011-2012, we observed 64 cases of AP: 52 mild-moderate, 12 severe; biliary 39, biliary in alcoholic chronic pancreatitis 5, unexplained recurrent 20. The clinical and instrumental evaluation of the 20 cases of unexplained AP showed 6 patients with biliary sludge, 4 microlithiasis, 4 sphincter of Oddi dysfunction, and 6 cases that remained undefined. RESULTS Among 20 patients with recurrent, unexplained AP at initial etiological assessment, we performed 10 video laparo cholecystectomies (VLCs), 2 open cholecystectomies and 4 endoscopic retrograde cholangiopancreatography/endoscopic sphincterotomies (ERCP/ES) in patients who had undergone previous cholecystectomy; 4 patients refused surgery. Among these 20 patients, 6 had AP that remained unexplained after second-level imaging investigations. For these patients, 4 VLCs and 2 ERCP/ES were performed. Follow-up after six months was negative for further recurrence. CONCLUSION The recurrence of unexplained acute pancreatitis could be treated with empirical cholecystectomy and/or ERCP/ES in cases of previous cholecystectomy.

Abstract
BACKGROUND/OBJECTIVES Endoscopic ultrasonography (EUS) is an accurate imaging modality for delineating pancreatobiliary structures, however, its clinical application of acute pancreatitis (AP) is limited. Therefore, we sought to characterize the typical EUS features of AP and to determine whether early EUS findings may have prognostic significance. METHODS Between March 2008 and October 2010, 90 patients with AP and 90 patients without pancreatic disease who underwent EUS were enrolled. An EUS examination was performed within 48 h of admission in AP, and all EUS findings were retrospectively analyzed. RESULTS Among 90 patients, 27 (30%) were diagnosed with severe AP. Multivariate analysis revealed the presence of peripancreatic fluid (OR 13.9, 95%, CI: 1.6-123.6), heterogenous (OR 7.2, 95% CI: 1.7-30.4) and hypoechoic parenchymal echogenicity (OR 10.0, 95% CI: 3.9-25.8) were significant EUS features in AP, as compared to those in the control group. Comparison between mild and severe AP showed that geographic hyperechoic area (GHA) of pancreas was a predictive factor (OR 2.9, 95% CI: 1.1-8.2, p = 0.04) for the severe form, and that AP patients with GHA had significantly longer duration of fever, abdominal pain and hospital stay than those without GHA (5.5 vs. 1 day (s), p = 0.002; 4 vs. 3 days, p = 0.023; 11 vs. 8 days, p = 0.021, respectively). CONCLUSIONS Typical EUS features of AP are a heterogenous hypoechoic parenchymal changes with peripancreatic fluid collection. The novel EUS variable of GHA in the early phase of AP seems to have prognostic value and could be correlated with a worse clinical outcome.

Abstract
BACKGROUND In a population-based study, we examined recurrence rates of acute pancreatitis (AP) after cholecystectomy performed to prevent recurrences of AP. METHODS We abstracted data from medical records of all Olmsted county residents who underwent cholecystectomy at Mayo Clinic for the management of presumed gallstone or idiopathic AP between 1990 and 2005 (n = 239). Based on (i) significantly elevated liver enzymes (≥threefold increase of alanine aminotransferase or aspartate aminotransferase) on day 1 and (ii) the presence of gallstones/sludge in the gall bladder, we categorized patients into 4 groups: A (i + ii), B (i but not ii), C (ii but not i), and D (neither i nor ii). Recurrence rates of AP after cholecystectomy were determined in all groups. RESULTS The median follow-up after cholecystectomy was 99 months (range, 8-220). AP recurred in 13 of 142 patients (9%) in group A, 1 of 17 patients (6%) in group B, 13 of 57 patients (23%) in group C, and 14 of 23 patients (61%) in group D (P < .0001 D vs. all other groups and P = .001 C vs. groups A and B). No difference was seen in recurrence rates in groups A vs. B (P = 1.0). Recurrences were more frequent in patients with normal liver enzymes (A + B vs. C + D; P = .000003) and in patients without sonographic evidence of gallstones/sludge (A + C vs. B + D; P = .0008). CONCLUSION When AP is associated with significantly elevated liver enzymes on day 1, recurrence rates after cholecystectomy are low (9%). However, postcholecystectomy recurrence rates of AP are high in those without such laboratory abnormalities (34%), especially in those without gall bladder stones/sludge (61%) on abdominal ultrasonography. Our results raise doubts about the efficacy of cholecystectomy to prevent recurrent AP in patients with the absence of either a significant elevation of liver tests on day 1 of AP or gallstones and/or sludge in the gall bladder on initial ultrasound examination.

Abstract
OBJECTIVES The objectives of the study were to compare endoscopic ultrasonography (EUS) and magnetic resonance cholangiopancreatography (MRCP) in the etiological diagnosis of patients initially diagnosed with idiopathic acute pancreatitis and to determine the clinical and analytical factors related to the end result of these techniques. METHODS Forty-nine patients, initially diagnosed with idiopathic acute pancreatitis, were evaluated prospectively with EUS and MRCP. Diagnoses were compared between the 2 procedures. The clinical-evolutionary characteristics of these patients with regard to the results obtained with these techniques were compared. RESULTS In twenty-eight patients (57%), EUS and/or MRCP diagnosed at least 1 possible cause of acute pancreatitis. The diagnostic yield of EUS was higher than that of MRCP (51% vs 20%; P = 0.001). Cholelithiasis and biliary sludge (24%) were the most frequent EUS diagnoses, and pancreas divisum (8%) was the most frequent MRCP diagnosis. Only in 3 cases (6%) did MRCP identify additional features in patients etiologically undiagnosed using EUS. The EUS yield was lower in patients who had a previous cholecystectomy (11% vs 60%; P = 0.008). CONCLUSIONS Endoscopic ultrasonography and MRCP are useful techniques in the etiological diagnosis of acute pancreatitis of nonestablished cause. Endoscopic ultrasonography should be preferred for establishing a possible biliary etiology in patients who have not had a cholecystectomy.

EUS compared with endoscopy plus transabdominal US in the initial diagnostic evaluation of patients with upper abdominal pain. Gastrointest Endosc 2010; 72:967-74. [PMID: 20650452 PMCID: PMC3775486 DOI: 10.1016/j.gie.2010.04.007] [Citation(s) in RCA: 16] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/13/2009] [Accepted: 04/07/2010] [Indexed: 02/06/2023]
Abstract
BACKGROUND Primary upper endoscopy (EGD) and transabdominal US (TUS) are often performed in patients with upper abdominal pain. OBJECTIVE Primary: Determine whether the combination of EGD and EUS was equivalent to EGD plus TUS in the diagnostic evaluation of upper abdominal pain. Secondary: Compare EUS versus TUS in detecting abdominal lesions, and compare EGD by using an oblique-viewing echoendoscope versus the standard, forward-viewing endoscope in detecting mucosal lesions. DESIGN Prospective, paired design. SETTING Six academic endoscopy centers. PATIENTS This study involved patients with upper abdominal pain referred for endoscopy. INTERVENTION All patients had EGD, EUS, and TUS. The EGD was done using both an oblique-viewing echoendoscope and the standard, forward-viewing endoscope (randomized order) by two separate endoscopists in a blinded fashion, followed by EUS. TUS was performed within 4 weeks of EGD/EUS, also in a blinded fashion. FOLLOW-UP telephone interviews and chart reviews. MAIN OUTCOME MEASUREMENTS Diagnose possible etiology of upper abdominal pain and detect clinically significant lesions. RESULTS A diagnosis of the etiology of upper abdominal pain was made in 66 of 172 patients (38%). The diagnostic rate was 42 of 66 patients (64%) for EGD plus EUS versus 41 of 66 patients (62%) for EGD plus TUS, which was statistically equivalent (McNemar test; P = .27). One hundred ninety-eight lesions were diagnosed with either EUS or TUS. EUS was superior to TUS for visualizing the pancreas (P < .0001) and for diagnosing chronic pancreatitis (P = .03). Two biliary stones were detected only by EUS. Two hundred fifty-one mucosal lesions were similarly diagnosed with EGD with either the standard, forward-viewing endoscope or the oblique-viewing echoendoscope (kappa = 0.48 [95% CI, .43-.54]). EGD with the standard, forward-viewing endoscope was preferred for biopsies. LIMITATIONS No cost analysis. CONCLUSION The combination of EGD with EUS is equivalent to EGD plus TUS for diagnosing a potential etiology of upper abdominal pain. EUS is superior to TUS for detecting chronic pancreatitis. EGD combined with EUS should be considered in the first-line diagnostic evaluation of patients with upper abdominal pain.

Abstract
Endoscopic ultrasound (EUS) is often used to detect the cause of acute pancreatitis (AP) after the acute attack has subsided. The limited data on its role during hospitalization for AP are reviewed here. The ability of EUS to visualize the pancreas and bile duct, the sonographic appearance of the pancreas, correlation of such appearance to clinical outcomes and the impact on AP management are analyzed from studies. The most important indication for EUS appears to be for detection of suspected common bile duct and/or gall bladder stones and microlithiasis. Such an approach might avoid diagnostic endoscopic retrograde cholangio-pancreatography with its known complications. The use of EUS during hospitalization for AP still appears to be infrequent but may become more frequent in future.

Abstract
Idiopathic acute pancreatitis is a diagnostic challenge for gastroenterologists. The possibility of finding a cause for pancreatitis usually relies on how far the diagnostic study is taken. Endoscopic explorations such as endoscopic retrograde cholangiopancreatography and endoscopic ultrasonography can help to determine the cause of pancreatitis. Furthermore, microscopic bile examination and magnetic resonance cholangiopancreatography can also be helpful in the work up of these patients. In this article an approximation to the diagnostic approach to patients with idiopathic acute pancreatitis is made, taking into account the reported evidence with which to choose between the different available explorations.

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
OBJECTIVES To evaluate the diagnostic yield of endoscopic ultrasonography (EUS) in patients with idiopathic acute pancreatitis (IAP), find factors predictive of a positive EUS finding in these patients and investigate whether these etiological findings are maintained during follow-up. MATERIAL AND METHODS We performed EUS in patients with IAP between July 2004 and August 2007. We recorded epidemiological data, the number and severity of previous bouts of pancreatitis and gallbladder status. RESULTS A total of 44 patients were included in the study. EUS was normal in seven patients (16%). In the remaining 37 patients (84%) we found cholelithiasis (n = 3), microlithiasis (n = 20), chronic pancreatitis (n = 14), pancreas divisum (n = 3), pancreatic mass (n = 1), apudoma (n = 1), cystic tumor of the pancreas (n = 2) and choledocholithiasis (n = 2). Positive EUS findings were not influenced by sex, severity of pancreatitis or recurrent disease. Patients aged < 65 years (age > or < 65 years: 73.9% versus 95.2%; P = 0.097) and patients with gallbladder in situ (cholecystectomy versus non-cholecystectomy: 63.6% versus 90.9%; P = 0.054) showed a tendency to have positive EUS findings. Mean follow-up was 28.95 +/- 10.86 months (range 12-64 months; median 28 months). During follow-up the etiological diagnosis was changed in two patients, lowering the diagnostic yield to 79%. CONCLUSIONS EUS identified the cause of IAP in 79% of patients. Patients with gallbladder in situ and patients aged < 65 years showed a tendency to have positive EUS findings. The majority of the diagnoses provided by EUS are maintained during follow-up and seem to be reliable.

Abstract
In the care of acute pancreatitis, a prompt search for the etiologic condition of the disease should be conducted. A differentiation of gallstone-induced acute pancreatitis should be given top priority in its etiologic diagnosis because it is related to the decision of treatment policy. Examinations necessary for diagnosing gallstone-induced acute pancreatitis include blood tests and ultrasonography. Early ERCP/ES should be performed in patients with gallstone-induced acute pancreatitis if a complication of cholangitis and a prolonged passage disorder of the biliary tract are suspected. The treatment for bile duct stones with the use of ERCP/ES alone is not recommended in cases of gallstone-induced pancreatitis with gallbladder stones. Cholecystectomy for gallstone-induced acute pancreatitis should be performed using a laparoscopic procedure as the first option as soon as the disease has subsided.

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
OBJECTIVES Both endoscopic retrograde cholangiopancreatography (ERCP) and endoscopic ultrasonography (EUS) are commonly performed in the evaluation of idiopathic pancreatitis. However, comparative trials of these modalities are lacking, and thus the ideal endoscopic diagnostic strategy to evaluate idiopathic pancreatitis remains unknown. METHODS A decision analysis model of patients with 2 attacks of idiopathic pancreatitis with gallbladder in situ was constructed using TreeAge software. We analyzed cost and overall diagnostic ability of 3 strategies, namely, EUS, ERCP with manometry and bile aspiration, and laparoscopic cholecystectomy. RESULTS Using the base case analysis, initial EUS was the preferred initial modality for the diagnosis. The expected cost for initial EUS was $4469 compared with $4615 for ERCP and $6268 for laparoscopic cholecystectomy. For cholecystectomy to be the preferred strategy, the total cost would need to be less than $1314, well below any realistic cost estimate. If the prevalence of microlithiasis/sludge was greater than 80%, then cholecystectomy would be preferred, whereas ERCP would be preferred with a prevalence of less than 41%. CONCLUSIONS This cost minimization study identifies EUS as the least costly initial test for the diagnostic evaluation of patients with idiopathic pancreatitis with gallbladder in situ.

Abstract
Acute recurrent pancreatitis (ARP) is a common clinical condition that may be difficult to diagnose. Endoscopic ultrasound (EUS) is proposed to be a safe first line test of choice in the majority of patients. When interventions are needed to remove biliary stones, evaluate sphincter of Oddi or pancreas divisum, endoscopic retrograde cholangiopancreatography (ERCP) is recommended. Magnetic resonance cholangiopancreatography (MRCP) can be a suitable alternative from a diagnostic standpoint although may not be widely available. Finally, genetic testing is increasingly used to detect certain mutations that are associated with this diagnosis.

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
Recent advances in understanding of pancreatitis and advances in technology have uncovered the veils of idiopathic pancreatitis to a point where a thorough history and judicious use of diagnostic techniques elucidate the cause in over 80% of cases. This review examines the multitude of etiologies of what were once labeled idiopathic pancreatitis and provides the current evidence on each. This review begins with a background review of the current epidemiology of idiopathic pancreatitis prior to discussion of various etiologies. Etiologies of medications, infections, toxins, autoimmune disorders, vascular causes, and anatomic and functional causes are explored in detail. We conclude with management of true idiopathic pancreatitis and a summary of the various etiologic agents. Throughout this review, areas of controversies are highlighted.

Abstract
Acute pancreatitis is a disease caused by gallstones in 40-60% of patients. Identification of these patients is extremely important, since there are specific therapeutic interventions by endoscopic sphincterotomy and/or cholecystectomy. The combination of trans-abdominal ultrasound (stones in the gallbladder and/or main bile duct) and elevated serum alanine transaminase (circa >60 IU/l within 48 h of presentation) indicates gallstones as the cause in the majority of patients with acute pancreatitis. In the presence of a severe attack this is a strong indication for intervention by endoscopic sphincterotomy. The presence of a significant main bile duct dilatation is also strongly indicative of gallstones and should prompt the use of endoluminal ultrasonography: >8 mm diameter with gallbladder in situ, or >10 mm following cholecystectomy if aged <70 years and >12 mm, respectively, if > or = 70 years. In mild pancreatitis surgically fit patients should be treated by cholecystectomy, and intra-operative cholangiography, as pre-operative biliary imaging is not efficient in this setting. Patients who are not fit for cholecystectomy should undergo prophylactic endoscopic sphincterotomy to prevent further attacks. In the post-acute-phase, pancreatitis patients in whom the aetiology is uncertain should undergo endoluminal ultrasonography. Thisis the most sensitive method for the detection of cholelithiasis and choledocholithiasis and may reveal alternative aetiological factors such as a small ampullary or pancreatic cancer. A number of recent studies have shown that bile crystal analysis, a marker for microlithiasis, increases the yield of positive results over and above endoluminal ultrasonography, and should be considered as part of the modern investigative algorithm.

Abstract
BACKGROUND & AIMS Endoscopic ultrasound (EUS) achieves high-resolution images of the bile duct and pancreas, while avoiding the risks of ERCP (endoscopic retrograde cholangiopancreatography). It appears comparable to MRCP (magnetic resonance cholangiopancreatography), although its use is less widely disseminated. We aimed to summarize EUS test performance in suspected biliary disease with meta-analysis. METHODS MEDLINE search (January 1987-September 2006), selected reference lists, external experts, and manual search of abstracts were used. Studies permitting (re)construction of 2 x 2 tables for EUS versus a gold standard were used. Random-effects models were used to estimate pooled sensitivity and specificity after adjusting for a number of potential confounders. Summary receiver operating characteristic analysis, with the sensitivity corresponding to the point on the receiver operating characteristic curve where sensitivity equals specificity (Q*) and area under the curve, was performed. The effects of sample size, quality, disease prevalence and spectrum, pancreatitis, echoendoscope type, and EUS era on diagnostic performance were assessed. Performance regarding presence of obstruction, choledocholithiasis, and malignancy was analyzed. RESULTS Thirty-six eligible, non-overlapping studies met inclusion criteria (3532 subjects). EUS had a high overall pooled sensitivity (88%; 95% confidence interval, 85%-91%) and specificity (90%; 87%-93%) for biliary obstruction (area under the curve = 0.97; Q* = 0.92). EUS had higher sensitivity (89%; 87%-91%) and specificity (94%; 91%-96%) for choledocholithiasis than for malignancy (sensitivity, 78%; 69%-85%; specificity, 84%; 78%-91%). Smaller studies and ones mainly studying patients with suspected strictures were associated with lower test performance. CONCLUSIONS There is excellent overall accuracy for EUS in diagnosing choledocholithiasis, with less impressive results for malignancy (when fine-needle aspiration is not used).

Abstract
Pancreas is located behind the peritoneum without bone tissues, and general body examination and imaging detection have some limitations in the diagnosis of pancreatic diseases, which leads to the failure of early diagnosis. Endoscopic ultrasonography can provide us with high-resolution images of the pancreas the nearby structures, and it is an effective imaging modality for the diagnosis of pancreatic diseases with a high specificity and sensitivity. In this article, we reviewed the value of endoscopic ultrasonography in the diagnosis and interventional therapy for panceatic diseases.

Abstract
In approximately 20% of patients with acute pancreatitis, a cause is not established by history, physical examination, routine laboratory testing, and abdominal imaging. For those with a single unexplained attack, the role of invasive evaluation with endoscopic retrograde cholangiopancreatography is unsettled but has been generally limited to those patients with suspected bile duct stones or malignancy. Recent studies suggest that microlithiasis is causative in up to 75% of patients with an unexplained attack and gallbladder in situ, whereas sphincter of Oddi dysfunction is most prevalent in those with recurrent attacks who have previously undergone cholecystectomy. EUS has been shown to be highly accurate for the identification of gallbladder sludge, common bile duct stones, and pancreatic diseases. Given this apparent diagnostic utility, an EUS-based strategy may be a reasonable approach to evaluate patients with a single idiopathic attack. ERCP and sphincter of Oddi manometry should generally be reserved for patients with multiple unexplained attacks and negative EUS results, especially for those patients who have previously undergone cholecystectomy.

Abstract
BACKGROUND It is uncertain whether EUS should be performed after a single episode of idiopathic pancreatitis vs. recurrent episodes or if clinical factors can predict positive EUS findings. METHODS Consecutive patients with a single episode of idiopathic pancreatitis or with recurrent episodes underwent EUS (with analysis of bile for bilirubinate and cholesterol crystals, when possible). The diagnostic yield was compared for patients with a single episode of idiopathic pancreatitis and recurrent episodes (stratified by cholecystectomy status). Predictors of positive EUS findings were sought. EUS was considered "positive" if it identified any possible cause of pancreatitis other than chronic pancreatitis. RESULTS A total of 370 patients were studied (246 no-cholecystectomy group [134 single episode of idiopathic pancreatitis, 112 recurrent episodes] and 124 post-cholecystectomy group [67 single episode of idiopathic pancreatitis, 57 recurrent episodes]). Overall, EUS yielded a positive finding in 29.2%. For patients in the no-cholecystectomy group, positive EUS findings were not significantly more frequent in those with a single episode of idiopathic pancreatitis vs. those with recurrent episodes (31.3% vs. 32.1%; p = 0.89). In the post-cholecystectomy group, the yield was not significantly different for single episode of idiopathic pancreatitis (29.9%) vs. recurrent episodes (17.5%) ( p = 0.15). Chronic pancreatitis was the only abnormality identified in 30.9% of patients in the no-cholecystectomy group vs. 26.6% of those in the post-cholecystectomy group ( p = 0.24). It was the most common abnormality found in all 4 subgroups (range 16.4%-42.0%) and was approximately twice as frequent in patients with recurrent episodes vs. a single episode of idiopathic pancreatitis (no-cholecystectomy: 42.0% vs. 21.6%, p = 0.0008; post-cholecystectomy: 38.6% vs. 16.4%, p = 0.008). Analysis of bile revealed crystals in 38/80 (47.5%) patients in whom it could be performed. Patients with positive EUS findings tended to be older. CONCLUSIONS In patients with idiopathic pancreatitis, the yield of EUS is not significantly different after an initial attack or after recurrent attacks. Therefore, it is reasonable to perform EUS after an initial attack of idiopathic acute pancreatitis, especially in older patients.

Abstract
BACKGROUND The aim of the study was to evaluate endoscopic ultrasonography (EUS) as a single method for diagnosing cholecystolithiasis in patients with a clinical suspicion of cholecystolithiasis, but with a normal transabdominal ultrasonography (TUS). METHODS A prospective study was performed on patients with biliary type of colic and normal US of the gallbladder. All patients had at least one normal TUS examination (mean 2.1, range 1-5) performed by an experienced radiologist. All patients were subsequently examined with EUS. EUS examination was performed with either a mechanical radial scanning echo-endoscope (Olympus GF-UM20) or a linear echo-endoscope (Pentax FG32-UA or FG34-UA). Patients in whom EUS demonstrated cholecystolithiasis were offered laparoscopic cholecystectomy within 2 weeks. RESULTS A total of 35 patients (31 F and 4 M) were included. In 18 out of 35 (52.4%) patients cholecystolithiasis was diagnosed by EUS. In 15 out of 17 patients the EUS diagnosis was verified by surgery. At follow-up after 12 months, 13 of the 15 patients (87%) with verified gallbladder stones had no abdominal discomfort, whereas 2 patients (13%) complained of persistent and unchanged abdominal pain. CONCLUSION EUS seems to be a promising imaging method in the detection of microlithiasis in the gallbladder in patients with clear biliary colic and normal transabdominal US.

Abstract
Therapeutic endoscopy is now increasingly used to treat gallstone pancreatitis, acute pancreatitis of other aetiologies, chronic pancreatitis and complications associated with acute or chronic pancreatitis. This chapter is a brief review of the endoscopic interventions currently performed in patients with acute or chronic pancreatitis. These interventions include biliary and pancreatic endoscopic sphincterotomy at the major or minor papilla, stricture dilatation on the common bile duct or main pancreatic duct, stent placement in the biliary or pancreatic ducts, stone extraction with or without extracorporeal shock wave lithotripsy, and transmural or transpapillary drainage of pancreatic fluid collections. As most of the studies reported were uncontrolled and retrospective, uncertainties persist with regard to the best approaches for treating the patients concerned. Appropriate patient selection, adequate expertise, and a supporting multidisciplinary infrastructure are essential prerequisites of a high success rate in improving the clinical condition of these patients.

Abstract
Bile duct crystals collected either from the duodenum after gallbladder contraction or directly from bile duct aspiration are surrogates for gallbladder stones and microlithiasis. Whether bile crystals also serve as surrogates for bile duct stones or microlithiasis that forms in the bile duct after cholecystectomy is not known based on current data. Sphincter of Oddi dysfunction (SOD), due either to muscular spasm or sphincter fibrosis, is a cause of bile duct obstruction. Almost all of the literature on SOD involves patients who have had a prior cholecystectomy. Intuitively, obstruction at the SO following cholecystectomy would seem to lead to biliary stasis and predispose patients to bile duct microlithiasis. However, a recent study did not find bile duct crystals in patients with manometrically diagnosed SOD. The reason for this is unknown, although we hypothesize that cholesterol and bilirubinate crystals are not surrogates for brown pigment stones commonly found in patients following cholecystectomy.

Abstract
INTRODUCTION Compared with traditional radiologic methods for the detection of cholelithiasis, early transient hypertransaminasemia had provided a useful prediction of biliary etiology in patients with acute pancreatitis. AIM To investigate whether this application remains valid in the modern era of imaging for microlithiasis. METHODOLOGY The biochemical detection (LFT) of cholelithiasis was based on an increase in serum alanine transaminase of >or=80 IU/L (normal range, 0-45 IU/L) within 24 hours of admission. We have taken the collective findings of abdominal ultrasound (USS), endoscopic ultrasound (EUS), and postmortem examination to represent the denominator for the diagnosis of cholelithiasis against which comparison with LFT was made. RESULTS Of 68 patients with acute pancreatitis who were treated between October 2000 and December 2001, cholelithiasis was the etiological factor in 44 patients (65%). EUS detected microlithiasis in 5 of 10 patients examined. The etiology remained idiopathic in 3 patients (4.4%). The sensitivity, specificity, and positive and negative predictive values for USS were 86%, 100%, 100%, and 80% respectively; for LFT, they were 91%, 100%, 100%, and 86%; and for USS and LFT combined, they were 98%, 100%, 100%, and 96%, respectively. CONCLUSIONS In patients with acute pancreatitis, the biochemical analysis within 24 hours of admission provided a simple, rapid, and more accurate prediction of cholelithiasis than USS. The combination of LFT and USS detected or excluded a biliary etiology in almost all patients.

Abstract
With advances in noninvasive radiologic technology, additional adjunctive techniques are developing, and the roles for ERCP and EUS are continuously changing. In a diagnostic setting, ERCP is currently best reserved for patients with a high likelihood of needing endoscopic therapy, and EUS is especially useful for cases in which other imaging techniques have been inconclusive or are of inferior diagnostic capability. In a therapeutic setting, ERCP and EUS retain important roles in the management of both benign and malignant pancreatic and biliary disease. Certainly, technological advances also directly affect these modalities and expanded applications for ERCP and EUS for the pancreas and biliary tract are anticipated.

Abstract
Inflammation of the pancreas (pancreatitis) has many presentations in children and adolescents, ranging from intrauterine congenital onset with sequelae of early exocrine pancreatic insufficiency as in the diseases of cystic fibrosis and Shwachman-Diamond syndrome to postnatal onset as a consequence of embryologic anomalies affecting pancreatic drainage postulated to exist in pancreas divisum, or of traumatic, obstructive, hemodynamic, metabolic or biochemical insults. The etiology is often elusive with up to 30% of cases being idiopathic. Modern imaging modalities of endoscopic ultrasonography and magnetic resonance cholangiopancreatography extend the diagnostic power of conventional abdominal ultrasonography and computed tomography. In addition, there is increasing pediatric experience with endoscopic retrograde cholangiopancreatography. Medical management remains supportive, with optimal timing and indications for surgery in cases of pancreatic necrosis and pseudocyst assessed. Three temporal patterns of pancreatitis appear in children: acute pancreatitis, recurrent acute pancreatitis, and chronic pancreatitis. Acute pancreatitis is of abrupt onset, often attributable to a specific cause, and of variable severity and duration but self-limited with eventual resolution. Acute attacks of pancreatitis recurring after periods of remission characterize acute recurrent pancreatitis and indicate an intrinsic problem or susceptibility. Chronic pancreatitis is present in most of these cases in which pancreatic inflammation and destruction never completely remits.
