Abstract
Pancreatic divisum, a rare developmental anomaly of the pancreas, is infrequently observed in young individuals and is a recognized cause of recurrent acute pancreatitis, ultimately progressing to chronic pancreatitis. Chronic alcoholism is a prevalent and significant etiological factor contributing to both recurrent acute pancreatitis and chronic pancreatitis. This case report details the presentation of a 28-year-old patient with a history of chronic alcoholism, exhibiting recurrent acute pancreatitis evolving into chronic pancreatitis. Diagnostic evaluation revealed the presence of pancreatic divisum with associated pancreatic intraductal calculi, a common trigger for pancreatitis. The patient underwent successful management through endoscopic retrograde cholangiopancreatography, pancreatic lithotripsy, and pigtail pancreatic stent placement. This case highlights the complex interplay between chronic alcoholism leading to recurrent acute pancreatitis and pancreatic divisum, a rare congenital anomaly, which is found later in this case, complicating the disease.

Abstract
Children and adolescents are increasingly impacted by pancreatic disease. Interventional endoscopic procedures, including endoscopic retrograde cholangiopancreatography) and endoscopic ultrasonography, are integral to the diagnosis and management of many pancreatic diseases in the adult population. In the past decade, pediatric interventional endoscopic procedures have become more widely available, with invasive surgical procedures now being replaced by safer and less disruptive endoscopic interventions.

[PMID: 36641286 DOI: 10.1016/j.pan.2022.12.009] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/31/2022] [Revised: 12/06/2022] [Accepted: 12/13/2022] [Indexed: 01/16/2023]
Abstract
INTRODUCTION Pancreas Divisum (PD) is a common pancreatic ductal variant which is twice as common in pediatric patients with acute recurrent pancreatitis (ARP) relative to the general population (14% vs. 7%). Endoscopic retrograde cholangiopancreatography (ERCP) with minor papillotomy has been performed to facilitate drainage of pancreatic juice from the diminutive minor papilla to prevent pancreatitis and pancreatic damage. METHODS We searched our prospectively-maintained endoscopy databases for patients 18 and younger who underwent ERCP with minor papillotomy between 2009 and 2019. Demographic data, indications, procedural interventions and findings, as well as available clinical outcomes data were analyzed. RESULTS 54 ARP/PD patients underwent ERCP with minor papillotomy. Median age was 14 (range 7-18) years, and 26 (48.1%) patients were female. Post-ERCP pancreatitis developed in 10/54 patients (18.5%). 12-month post-ERCP clinical trajectory was available in 47/54 (87%) patients and most patients (38/47, 80.8%) improved clinically after minor papillotomy, with 9/47 (19.1%) experiencing resolution of pancreatitis episodes and none indicated worsening severity or frequency of pancreatitis episodes following ERCP. CONCLUSION The majority of children and adolescents with PD and ARP who underwent ERCP with minor papillotomy experienced subjective improvement in their symptoms following the intervention. These data suggest that ERCP with minor papillotomy for pediatric patients with PD and ARP is beneficial and may be curative in a subset of patients-higher rates of improvement than have been previously reported in adults.

Abstract
Acute pancreatitis is one of the most commonly encountered etiologies in the emergency setting, with a broad spectrum of findings that varies in severity from mild interstitial pancreas to severe forms with significant local and systemic complications that are associated with a substantial degree of morbidity and mortality. In this article the radiological aspect of the terminology and classification of acute pancreatitis are reviewed. The roles of ultrasound, computed tomography, and magnetic resonance imaging in the diagnosis and evaluation of acute pancreatitis and its complications are discussed. The authors present a practical image-rich guide, applying the revised Atlanta classification system, with the goal of facilitating radiologists to write a correct report, and reinforcing the radiologist’s role as a key member of a multidisciplinary team in treating patients with acute pancreatitis. Computed tomography is the most performed imaging test for acute pancreatitis. Nevertheless, MRI is useful in many specific situations, due to its superiority soft tissue contrast resolution and better assessment of biliary and pancreatic duct, for example in the ductal disconnection. The purpose if this article is to review recent advances in imaging acquisition and analytic techniques in the evaluation of AP.

Abstract
CLINICAL/METHODOLOGICAL ISSUE Diagnostic and clinical relevance of pancreas divisum. STANDARD RADIOLOGICAL METHODS Ultrasonography (US), magnetic resonance cholangiopancreatography (MRCP), magnetic resonance imaging (MRI), computed tomography (CT), endoscopic retrograde cholangiopancreatography (ERCP). PERFORMANCE Pancreas divisum is an anatomic variation of pancreatic duct system with an incidence in general population of about 10%. It can become symptomatic in approximately 5% of patients. MRI with MRCP is the method of choice to diagnose pancreas divisum. ACHIEVEMENTS MRCP is equal to ERCP in diagnosing pancreas divisum in routine clinical practice as it is noninvasive, offers the possibility to evaluate the adjacent tissues and has almost no contraindications. PRACTICAL RECOMMENDATIONS It is important to be familiar with the anatomy of the pancreatic duct system in order to plan interventional procedures for symptomatic patients in due time.

Abstract
PURPOSE Wirsungocele is a rare cystic dilatation of the main pancreatic duct seen at the terminal portion of the duct of Wirsung. The purpose of our study is to evaluate the diagnostic value of MRCP in detection of Wirsungocele and the association between the MRCP-determined size of Wirsungocele and the MRCP-clinical findings of pancreatitis. METHODS Thirty-four patients with reported 'Wirsungocele' were analyzed in the study. Two radiologists reviewed MRCP/S-MRCP images for the presence and diameter of Wirsungocele (WD), main pancreatic duct dilatation (MPDD), side branch ectasia (SBE), acinarization, and duodenal filling grade. Electronic medical record review included symptoms (abdominal pain), signs (recurrent acute/chronic pancreatitis), and select laboratory testing (serum amylase and lipase). Inter-reader agreement values were calculated by ICC. Pearson correlation analysis was performed to evaluate the association of WD with radiological and clinical findings. The comparison of WD on MRCP versus S-MRCP was calculated by Wilcoxon test. Mann-Whitney U test was used for two independent variable comparisons. RESULTS The sensitivity of MRCP for the detection of Wirsungocele calculated using the S-MRCP and ERCP as the reference method was 76.9% and 100%, respectively. There was a significant difference in the diameter of Wirsungocele measured by MRCP vs S-MRCP (p < 0.001). There was good inter-reader agreement for the detection of Wirsungocele on MRCP and measurement of WD on MRCP and S-MRCP (ICC: 0.79, 0.89, and 0.80, respectively, p < 0.001). There was a significant difference in WD between the patients with and without MPDD (p < 0.05). There was a significant positive correlation between WD and MPDD (r = 0.66, p < 0.05). WD was significantly associated with recurrent acute pancreatitis (p < 0.05). CONCLUSION MRCP is a highly sensitive and non-invasive imaging tool for detection of Wirsungocele. Greater Wirsungocele diameter is associated with MPDD and recurrent acute pancreatitis.

Abstract
BACKGROUND Islet isolation is an essential process in every human islet transplantation protocol. Intraductal enzyme delivery followed by adequate distention of the pancreas is the most critical step in islet isolation. Anomalies of the pancreatic duct system can significantly affect this process. Thus, identification and characterization of ductal patency is of paramount importance to achieve optimal islet isolation. AIMS To investigate the frequency of duct obliteration in the human pancreas and explore donor/patient characteristics associated with specific ductal variations. METHODS We examined ductal patency of pancreata allocated for islet allotransplantation (n = 597) and autotransplantation (n = 21) after removal of the duodenum during islet isolation procedure. Donor/patient factors were reviewed from the batch files. RESULTS Among 559 deceased donor pancreata without pancreas divisum (n = 38, 6.4%), both ducts were patent in 50.1%, only ventral duct was patent in 46.7%, and only dorsal duct was patent in 3.2%. Donor age was not associated with the frequency of obliterated dorsal duct. Black race tended to have the higher frequency of patent dorsal duct. As expected, pancreas divisum was more frequent in chronic pancreatitis cases (n = 6, 28.6%). Within 7 cases of chronic pancreatitis with unknown etiology, we encountered one case of ventral duct obliteration. CONCLUSIONS The minor duodenal papilla and aging do not likely play an important role in the occurrence of dorsal duct obliteration. Although frequency of obliterated ventral duct was low in our population, physicians, including gastroenterologists and endoscopists, as well as islet transplantation researchers should be aware of this possibility.

Abstract
BACKGROUND/AIM Biliary tree and pancreatic duct can appear in different variations whose proper understanding is obligatory for surgeons. Magnetic resonance cholangiopancreatography (MRCP) is considered a safe and accurate tool for evaluating biliary tree and pancreatic duct. Typical anatomy for right hepatic duct (RHD) and left hepatic duct (LHD) is reported as 57% and 63%, respectively. The most common (4-10%) pancreatic anomaly is divisum. In the present study, we evaluated and determined the prevalence of biliary tree and pancreatic duct variations among patients at a university hospital. MATERIALS AND METHODS The MRCP records of 370 patients from 2015 to 2017 were obtained for cross-sectional study. Images were retrospectively reviewed for variations by two independent senior radiologists. Demographic data were obtained for all the patients. Huang et al. classification was used for RHD and LHD variations. The cystic duct was reported based on its course and insertion pattern. The pancreatic duct was observed for the presence of divisum, its course, and configuration. RESULTS Three hundred and twenty-five patients were included in the final study. Most commonly observed variant for RHD were A1 (34.2%) and A2 (32.2%). For LHD, B1 (71.4%) was the most common variant. Cystic duct insertion was commonly seen as right lateral insertion (27.7%). Pancreatic divisum was observed in 0.6% of cases. Nationality, origin, and gender-specific variations were obtained. CONCLUSION Variations in biliary anatomy and pancreatic duct are very diverse and extend from the intrahepatic biliary system down to the pancreas. Performing a similar study on a larger population is mandatory to illustrate the range of variations present within the community.

Abstract
Developmental anomalies of the pancreas include more common entities such as pancreas divisum and annular pancreas, and unusual entities such as heterotopic pancreas. While these anomalies can present a diagnostic challenge to the radiologist, when the pancreatic tissue involved in these processes develops pancreatitis, the radiographic appearance can present a diagnostic dilemma. Awareness of these pancreatic anomalies and familiarity with their appearance when inflamed is necessary to distinguish pancreatitis in the developmentally anomalous pancreas from other inflammatory or neoplastic processes.

Abstract
The biliary tree and the pancreatic ducts originate from different buds of the primitive foregut. A plethora of anatomical variants and congenital anomalies have been described for both the biliary and the pancreatic duct systems, although they are usually asymptomatic. However, in some cases, these abnormalities can lead to serious clinical scenarios, especially when involving the biliopancreatic junction, with consequent mixing and reflux of the two different juices. To the best of our knowledge, we present the first case of pancreas divisum ducts draining into a choledochal cyst, with the lower third of the choledochus configuring a common biliopancreatic duct, in a child suffering from cholelithiasis and acute pancreatitis.

Abstract
OBJECTIVE This study was designed to assess the diagnostic accuracy of standard nonsecretin-enhanced preprocedural magnetic resonance imaging/cholangiopancreatography (MRI/MRCP) in patients with and without pancreas divisum. METHODS Patients undergoing MRI/MRCP followed by endoscopic retrograde cholangiopancreatography with between 2009 and 2016 were reviewed. The diagnostic accuracy of the MRI/MRCP was evaluated against the pancreatography. A subsequent independent blinded re-review performed by an expert abdominal radiologist was also evaluated. Multivariate binary logistic regression was performed to assess the impact of clinicopathologic factors on the diagnostic accuracy. RESULTS A total of 189 patients were included in analysis. The sensitivity, specificity, positive predictive value, and negative predictive value of MRI/MRCP for pancreas divisum were 63%, 97%, 94%, and 82% initially and 81%, 91%, 91%, and 82% on the expert review. Motion artifact, the presence of pancreatic tumor, and pancreatic necrosis were not found to significantly impact the accuracy. A normal diameter pancreatic duct (P = 0.04) and complete divisum anatomy were correlated with improved accuracy (P = 0.001). CONCLUSIONS Although expert review, normal duct diameter, and complete divisum are associated with increased sensitivity, pancreas divisum may be uncharacterized by preprocedural MRI in 19% to 37% of patients before the index endoscopic retrograde cholangiopancreatography.

Abstract
OBJECTIVES The aim of this study was to evaluate the long-term outcomes of therapeutic endoscopic retrograde cholangiopancreatography (ERCP) for pediatric patients with pancreas divisum (PD) presenting with acute recurrent pancreatitis (ARP) or chronic pancreatitis (CP). METHODS Between May 2008 and August 2017, pediatric patients with PD who received endotherapy at Ruijin Hospital were identified and grouped according to clinical presentation, namely ARP and CP. Primary success was defined as patients' improvement in symptoms after index ERCPs, without further intervention or any analgesic. RESULTS A total of 74 ERCPs were performed in 38 pediatric patients. The frequency of at least 1 genetic mutation identified in patients with ARP and CP was 44.4% and 68.4%, respectively. Patients with CP required more ERCPs than those with ARP (2.4 ± 1.7 vs. 1.1 ± 0.4, P = 0.005). The incidence of post-ERCP complications was 14.9%, including pancreatitis of 13.5% and hemorrhage of 1.4%. During a median follow-up duration of 41 months (range, 12-123 months), the frequency of pancreatitis episodes decreased significantly from 2.31 to 0.45 (P < 0.0001). The 25% recurrence and reintervention rates were estimated at 25 and 48 months, respectively, without significant difference between patients with ARP or CP. There was a nonsignificant trend towards a higher rate of primary success in patients with ARP than those with CP (92.9% vs. 69.6%, P = 0.123). After further endotherapy, 91.3% patients with CP improved clinically. CONCLUSIONS Therapeutic ERCP is an effective and safe intervention for pediatric patients with symptomatic PD. Patients presenting with CP seem to achieve improvement after additional ERCPs.

Abstract
PURPOSE Elucidating the association between pancreatic ductal anomalies and chronic asymptomatic pancreatic hyperenzymemia using magnetic resonance cholangiopancreatography. METHODS We conducted a single-center, retrospective, case-control study. The healthy community group comprised 554 subjects who participated in a paid, whole-body health checkup program. The patient group comprised 14 subjects with idiopathic pancreatic hyperamylasemia or hyperlipasemia. All subjects underwent magnetic resonance cholangiopancreatography. The clinical features and incidence rates of pancreatic ductal anomalies were then compared between the groups. RESULTS Compared to the healthy community group, the patient group was significantly more likely to be ≥ age 65 (71.4% of patient group vs. 22.1% of healthy community group), have a history of diabetes mellitus (21.4% vs. 5.4%) or hypertension (35.7% vs. 11.4%), and to have pancreas divisum (21.4% vs. 2.7%), meandering main pancreatic duct (21.4% vs. 4.1%), Wirsungocele (14.3% vs. 1.1%), or dilated main pancreatic duct (14.3% vs. 2.3%). Multivariate analysis found that age ≥ 65 (odds ratio 8.76), presence of pancreas divisum (odds ratio 13.2), meandering main pancreatic duct (odds ratio 8.95), and Wirsungocele (odds ratio 17.6) were independent factors significantly associated with chronic asymptomatic pancreatic hyperenzymemia. CONCLUSIONS Pancreas divisum, meandering main pancreatic duct, and Wirsungocele were independently associated with chronic asymptomatic pancreatic hyperenzymemia.

Abstract
OBJECTIVES To investigate the radiological findings prognostic for the development of pancreatic adenocarcinoma in a cohort of patients with hepatocellular carcinoma, using multiphasic computed tomography (CT). METHODS A case-cohort study performed in a single university hospital. A database of patients who received hepatocellular carcinoma (HCC) treatment and trimonthly follow-up with four-phase dynamic CT was used (n = 1848). The cohort group was randomly extracted from the database (n = 103). The case group comprised nine patients from the database who developed pancreatic adenocarcinoma. The radiological findings were assessed during follow-up (average, 32 months). RESULTS The incidence of pancreatic mass, inhomogeneous parenchyma, loss of fatty marbling and main pancreatic duct dilatation gradually increased from 4 to 13 months before the diagnosis of pancreatic adenocarcinoma. There was a significantly higher incidence of pancreatic mass, inhomogeneous parenchyma and loss of fatty marbling on CT at baseline (average, 34 months before diagnosis) in the case group compared with the cohort group (P values < 0.01) and those findings at baseline were revealed as prognostic factors for pancreatic carcinogenesis, respectively (log-rank test, P values < 0.001). CONCLUSIONS Several radiological findings observed on multiphasic CT can assist in predicting pancreatic carcinogenesis well in advance. KEY POINTS • Pancreatic findings in multiphasic CT help predict development of pancreatic adenocarcinoma. • Key findings are mass, inhomogeneous parenchyma and loss of fatty marbling. • Those findings were observed 34 months before confirmed diagnosis of adenocarcinoma. • Those findings were prognostic factors for pancreatic carcinogenesis.

Abstract
OBJECTIVE The purpose of this study is to assess the additional value of secretin-enhanced MRCP over conventional (non-secretin-enhanced) MRCP in diagnosing disease in patients with recurrent acute pancreatitis. MATERIALS AND METHODS A retrospective review of a radiology database found 72 patients with recurrent acute pancreatitis who had secretin-enhanced MRCP and ERCP correlation within 3 months of each other between January 2007 and December 2011. Of these patients, 54 had no history of pancreatic tumor or surgery and underwent MRI more than 3 months after an episode of acute pancreatitis. In addition, 57 age- and sex-matched control subjects with secretin-enhanced MRCP and ERCP correlation and without a diagnosis of recurrent acute pancreatitis or chronic pancreatitis were enrolled as the control group. All studies were anonymized, and secretin-enhanced MRCP images (image set A) were separated from conventional 2D and 3D MRCP and T2-weighted images (image set B). Image sets A and B for each patient were assigned different and randomized case numbers. Two blinded reviewers independently assessed both image sets for ductal abnormalities and group A image sets for exocrine response to secretin. RESULTS There were statistically significantly more patients with recurrent acute pancreatitis with reduced exocrine function compared with patients in the control group (32% vs 9%; p < 0.01) on secretin-enhanced images. Patients with recurrent acute pancreatitis were more likely to have side branch dilation (p = 0.02; odds ratio, 3.6), but not divisum, compared with the control group. Secretin-enhanced images were superior to non-secretin-enhanced images for detecting ductal abnormalities in patients with recurrent acute pancreatitis, with higher sensitivity (76% vs 56%; p = 0.01) and AUC values (0.983 vs 0.760; p < 0.01). CONCLUSION Up to one-third of patients with recurrent acute pancreatitis showed exocrine functional abnormalities. Secretin-enhanced MRCP had a significantly higher yield for ductal abnormalities than did conventional MRI and should be part of the MRCP protocol for investigation of patients with recurrent acute pancreatitis.

Abstract
BACKGROUND Magnetic resonance cholangio-pancreatography (MRCP) findings in people with chronic asymptomatic pancreatic hyperenzymemia (CAPH) have shifted the hypothesis that CAPH is always non-pathological. However, there have been no studies including both secretin-MRCP (S-MRCP) and endoscopic ultrasonography (EUS) to examine the pancreatic morphology in these subjects. AIM To prospectively assess the diagnostic approach for CAPH using both pancreatic EUS and S-MRCP. METHODS In a case-control prospective study from January 2010 to December 2014, 68 consecutive subjects with CAPH were scheduled to undergo S-MRCP and EUS (CAPH group) in a tertiary care setting. In the same period, the EUS findings of this group were compared with 68 patients examined by EUS alone for submucosal lesions of the gastric fundus, matched for sex and age (control group). RESULTS EUS detected pancreatic alterations in 60.3% of the CAPH group and 13.2% of controls (p<0.001). S-MRCP showed pancreatic alterations in 51.5% in the CAPH group. With the combined procedures, pancreatic abnormalities were detected in 63.3%. The diagnoses established by the two techniques were concordant in 51 (75%) of the 68 CAPH subjects; in the remaining 17 (25%) the two methods gave additional information. CONCLUSIONS In people with CAPH S-MRCP and EUS are both recommended in order to detect pancreatic abnormalities before this biochemical alteration is confirmed as benign CAPH, or Gullo's syndrome.

Abstract
AIM To determine the non-biased prevalence and clinical significance of ansa pancreatica in patients with acute pancreatitis using magnetic resonance imaging (MRI).
METHODS Our institutional review board approved this cross-sectional study, which consisted of a community-based cohort of 587 consecutive participants in a whole-body health-check program, and 73 subjects with episode of acute pancreatitis (55 patients with a single episode of acute pancreatitis, and 18 patients with recurrent acute pancreatitis). All of the subjects underwent abdominal MRI including magnetic resonance cholangiopancreatography, medical examinations, and blood tests. Two board-certified, diagnostic, abdominal radiologists evaluated the images, and ansa pancreatica was diagnosed based on its characteristic anatomy on MRI.
RESULTS Compared with the community group [5/587 (0.85%)], patients with recurrent acute pancreatitis had a significantly higher frequency of ansa pancreatica [2/18 (11.1%)] (P = 0.016; OR = 14.3; 95%CI: 1.27-96.1), but not compared with patients with single-episode acute pancreatitis [1/55 (1.8%)] (P = 0.42; OR = 2.1; 95%CI: 0.44-19.7). Multiple logistic regression analysis using age, alcohol intake, presence of ansa pancreatica, and presence of autoimmune disease as independent covariates, revealed a significant relationship between the presence of ansa pancreatica and recurrent acute pancreatitis. The presence of autoimmune disease was also significantly associated with the onset of recurrent acute pancreatitis. On the other hand, neither age nor alcohol intake were significantly related to the onset of recurrent acute pancreatitis.
CONCLUSION The present study is the first to provide robust evidence that the presence of ansa pancreatica is significantly associated with recurrent acute pancreatitis.

Abstract
OPINION STATEMENT Recurrent acute pancreatitis (RAP) is defined based on the occurrence of two or more episodes of acute pancreatitis. RAP is differentiated from chronic pancreatitis based on the presence of a normal morphological appearance of the pancreas between episodes. RAP can be due to a variety of etiologies including common bile duct stones or sludge, sphincter of Oddi dysfunction (SOD), pancreas divisum (PD), anomalous pancreaticobiliary junction, genetic mutations, and alcohol related. In approximately 30 % of patients, the etiology of RAP is unclear and the term "idiopathic" is used. Endoscopic retrograde cholangiopancreatography (ERCP) can be utilized in both the diagnosis and the initial management of RAP, but it has known limitations and risks. Since gallbladder sludge and SOD account for most cases with RAP, cholecystectomy and, eventually, endoscopic biliary and/or pancreatic sphincterotomy are performed as a part of management. In patients with PD-associated RAP, data from uncontrolled and primarily retrospective studies point toward a benefit from minor papillary endoscopic intervention. However, given the lack of quality data from prospective randomized controlled trials (RCTs), endoscopic management in such patients remains an individualized decision, and RCTs are needed to ascertain its true long-term benefit. Future studies to investigate the role of endoscopic therapy in preventing progression to chronic pancreatitis are needed.

Abstract
Background Iterative reconstruction methods have attracted attention for reducing radiation doses in computed tomography (CT). Purpose To investigate the detectability of pancreatic calcification using dose-reduced CT reconstructed with model-based iterative construction (MBIR) and adaptive statistical iterative reconstruction (ASIR). Material and Methods This prospective study approved by Institutional Review Board included 85 patients (57 men, 28 women; mean age, 69.9 years; mean body weight, 61.2 kg). Unenhanced CT was performed three times with different radiation doses (reference-dose CT [RDCT], low-dose CT [LDCT], ultralow-dose CT [ULDCT]). From RDCT, LDCT, and ULDCT, images were reconstructed with filtered-back projection (R-FBP, used for establishing reference standard), ASIR (L-ASIR), and MBIR and ASIR (UL-MBIR and UL-ASIR), respectively. A lesion (pancreatic calcification) detection test was performed by two blinded radiologists with a five-point certainty level scale. Results Dose-length products of RDCT, LDCT, and ULDCT were 410, 97, and 36 mGy-cm, respectively. Nine patients had pancreatic calcification. The sensitivity for detecting pancreatic calcification with UL-MBIR was high (0.67–0.89) compared to L-ASIR or UL-ASIR (0.11–0.44), and a significant difference was seen between UL-MBIR and UL-ASIR for one reader (P = 0.014). The area under the receiver-operating characteristic curve for UL-MBIR (0.818–0.860) was comparable to that for L-ASIR (0.696–0.844). The specificity was lower with UL-MBIR (0.79–0.92) than with L-ASIR or UL-ASIR (0.96–0.99), and a significant difference was seen for one reader (P < 0.01). Conclusion In UL-MBIR, pancreatic calcification can be detected with high sensitivity, however, we should pay attention to the slightly lower specificity.

Abstract
There are several common causes of acute pancreatitis, principally excessive alcohol intake and gallstones, and there are many rare causes. However, cases of pancreatitis still occur in the absence of any recognizable factors, and these cases of idiopathic pancreatitis suggest the presence of unrecognized etiologies. Five cases of acute pancreatitis in four patients came to attention due to a strong temporal association with exposure to nerve stimulators and energy drinks. Given that these cases of pancreatitis were otherwise unexplained, and given that these exposures were not clearly known to be associated with pancreatitis, we performed a search for precedent cases and for mechanistic bases. No clear precedent cases were found in PubMed and only scant, weak precedent cases were found in public-health databases. However, there was a coherent body of intriguing literature in support of a mechanistic basis for these exposures playing a role in the etiology of pancreatitis.

Abstract
BACKGROUND The clinical significance of cholesterolosis has not been well established but there are some provocative, if not robust, studies of the role it may play in the pathophysiology of pancreatitis and biliary dyskinesia, as well as hypercholesterolemia. Our aim was to take advantage of a very large cholecystectomy (CCY) database to support or refute these potentially important reported associations. MATERIALS AND METHODS A retrospective review of 6868 patients who underwent CCY from 2001-2013 was performed. Comparisons were made using the student t-test for continuous and chi-square analysis for categorical, variables. RESULTS Among patients for whom the CCY was the primary operation, 1053 (18%) had cholesterolosis and 4596 did not. Compared to those without cholesterolosis, those with cholesterolosis were no more likely to have elevated cholesterol levels (P = 0.64) nor low gallbladder ejection fraction (P = 0.2). To evaluate cholesterolosis as a cause of pancreatitis, all patients with gallstones were eliminated, leaving 639 patients. Among these, not only was cholesterolosis not associated with more pancreatitis, but rather there was not a single patient with or without cholesterolosis who had pancreatitis. CONCLUSIONS Despite prior reports of associations between cholesterolosis and elevated serum cholesterol, depressed ejection fraction, and increased risk of pancreatitis, careful analysis of this current, larger data set does not support these associations. Any patient with stones or sludge, or with biliary dyskinesia, and appropriate symptoms, should be considered for CCY, with or without suspected cholesterolosis.

Abstract
PURPOSE To assess the additional value of secretin-enhanced MRCP (SMRCP) over conventional MRCP in diagnosing divisum. METHODS Retrospective HIPAA-compliant and IRB-approved review found 140 patients with SMRCP and ERCP correlation within 6 months of each other. All studies were anonymized and the SMRCP images (SMRCP image set) were separated from 2D and 3D MRCP and axial and coronal T2-weighted images (conventional MRI image set). Each image set on each patient was assigned different and randomized case numbers. Two reviewers (R1 and R2) independently reviewed the image sets for divisum vs. no divisum, complete divisum vs. incomplete divisum, and the certainty of diagnosis (1 = definitely certain, 2 = moderately certain, and 3 = unsure). ERCP findings were taken as gold standard. RESULTS There was no difference in age and gender between the divisum (n = 97, with 13 incomplete divisum) and no divisum (n = 43) groups. In diagnosing divisum anatomy, the sensitivity was higher for SMRCP compared to conventional MRI for R1 (84.5 vs. 72.2, p = 0.02) but not R2 (89.7 vs. 84.4, p = 0.25). The specificity was higher in SMRCP image set compared to conventional MRI (R1: 88.1 vs. 76.2, p = 0.01; R2: 81.4 vs. 65.1, p < 0.001). The mean area under ROC curve was higher for SMRCP image set (R1: 0.86 vs. 0.74, p = 0.01; R2: 0.87 vs. 0.74, p = 0.01). The certainty of diagnosis was higher in SMRCP image set compared to conventional MRI (p = 0.02 for both reviewers). SMRCP was not found to be superior in distinguishing incomplete from complete divisum. The main reasons for erroneous SMRCP diagnosis were the presence of an ansa loop in the main duct and ductal strictures due to chronic pancreatitis. CONCLUSION Even though the reviewers had more sequences (axial and coronal) to evaluate in the non-secretin image set, there was some improvement in diagnosing divisum with SMRCP.

AIM: To assess the rate of relapses of acute pancreatitis (AP), recurrent AP (RAP) and the evolution of endosonographic signs of chronic pancreatitis (CP) in patients with pancreas divisum (PDiv) and RAP.
METHODS: Over a five-year period, patients with PDiv and RAP prospectively enrolled were divided into two groups: (1) those with relapses of AP in the year before enrollment were assigned to have endoscopic therapy (recent RAP group); and (2) those free of recurrences were conservatively managed, unless they relapsed during follow-up (previous RAP group). All patients in both groups entered a follow-up protocol that included clinical and biochemical evaluation, pancreatic endoscopic ultrasonography (EUS) every year and after every recurrence of AP, at the same time as endoscopic retrograde cholangiopancreatography (ERCP).
RESULTS: Twenty-two were treated by ERCP and 14 were conservatively managed during a mean follow-up of 4.5 ± 1.2 years. In the recent RAP group in whom dorsal duct drainage was achieved, AP still recurred in 11 (57.9%) after the first ERCP, in 6 after the second ERCP (31.6%) and in 5 after the third ERCP (26.3%). Overall, endotherapy was successful 73.7%. There were no cases of recurrences in the previous RAP group. EUS signs of CP developed in 57.9% of treated and 64.3% of untreated patients. EUS signs of CP occurred in 42.8% of patients whose ERCPs were successful and in all those in whom it was unsuccessful (P = 0.04). There were no significant differences in the rate of AP recurrences after endotherapy and in the prevalence of EUS signs suggesting CP when comparing patients with dilated and non-dilated dorsal pancreatic ducts within each group.
CONCLUSION: Patients with PDiv and recent episodes of AP can benefit from endoscopic therapy. Effective endotherapy may reduce the risk of developing EUS signs of CP at a rate similar to that seen in patients of previous RAP group, managed conservatively. However, in a subset of patients, endotherapy, although successful, did not prevent the evolution of endosonographic signs of CP.

Acinarization (parenchymal blush) observed during secretin-enhanced MRCP: clinical implications. AJR Am J Roentgenol 2014; 203:607-14. [PMID: 25148164 DOI: 10.2214/ajr.13.11414] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 01/18/2023]
Abstract
OBJECTIVE T2 hyperintensity of pancreatic acini during secretin-enhanced MRCP is called "acinarization." We sought to determine the clinical significance of this finding. MATERIALS AND METHODS Patients were selected if the radiology report included the phrases "acin*" (where * represented a wild card search) or "blush" using the institution's customized lexicon-search software. Sixty-seven consecutive patients without acinarization on secretin-enhanced MRCP who also underwent ERCP were enrolled as the control group. The intensity of acinarization was classified into three groups: grade 0, no visible acinarization; grade 1, barely visible parenchymal hyperintensity; or grade 2, easily visible parenchymal hyperintensity. ERCP findings of ductal abnormalities and basal pancreatic sphincter manometry were recorded. RESULTS There were higher frequencies of divisum (p = 0.001) and of a clinical history of recurrent acute pancreatitis (p < 0.001) and higher basal pancreatic sphincter of Oddi manometric pressure measurements (p = 0.008) in the acinarization group. There was no difference in the frequency of ERCP-defined chronic pancreatitis (p = 0.10) between the groups. In patients with acinarization, a higher mean sphincter pressure was seen in patients with more intense acinarization than in those with faint acinarization, but this difference was not significant (p = 0.22). Ampullary tumors were found in four patients with acinarization. CONCLUSION Acinarization probably occurs in patients with a propensity for increased pancreatic ductal pressure (i.e., patients with divisum, elevated basal pancreatic sphincter pressure, ampullary tumor) and adequate exocrine function (absence of severe chronic pancreatitis).

Abstract
Clinical literature indicates that pancreas divisum (PD) is present in 3-22% of the population and may be associated with an increased risk of pancreatitis. PD is a developmental variant wherein the duct systems derived from the dorsal and ventral pancreatic buds are not fused. Hence secretions from the head, neck, body, and tail, which develop from the dorsal bud, must pass through the minor duodenal papilla. The smaller uncinate process, derived from the ventral bud, drains through the major duodenal papilla. The purpose of this study was: (1) to do a cadaveric dissection to confirm whether PD is common in donors who had not been selected because they had pancreatitis and (2) to determine the frequency of PD descriptions in anatomy, embryology, pathology, and surgery books in our libraries. For our anatomical study, pancreata of eight human donors were dissected. Dye was injected into the ducts so that any communications between main and accessory ducts could be easily located. For our literature review, 22 anatomy, 14 embryology, 11 pathology, and 26 surgery books were examined for mention of PD. PD was unambiguously identified in two donor cadavers. However, only 14% of the anatomy plus embryology books compared to 70% of the surgery plus pathology books describe PD. Cadaveric dissection confirms that PD is indeed prevalent. The prevalence of PD with its increased risk of pancreatitis merits inclusion of this topic in textbooks of anatomy and embryology.

Abstract
OBJECTIVE A subpopulation of patients with pancreas divisum experience symptomatic events such as recurrent acute pancreatitis and chronic pancreatitis. Minor papilla sphincterotomy has been reported as being an effective treatment. The aim of this study was to evaluate the safety and efficacy of endoscopic balloon dilation for the minor papilla. METHODS Between 2000 and 2012, 16 patients were retrospectively included in this study. After endoscopic balloon dilation for the minor papilla was received, a pancreatic stent or a nasal pancreatic drainage catheter was placed for 1 week. If a stricture or obstruction was evident, it was treated with balloon dilation followed by long-term stent placement (1 year). When an outflow of pancreatic juice was disturbed by a pancreatic stone, endoscopic stone extraction was performed. RESULTS Balloon dilation and stent placement were achieved and were successful in all the cases (16/16; 100%). Clinical improvement was achieved in 7 (84.7%) of the 9 patients with recurrent acute pancreatitis and in 6 (85.7%) of the 7 patients with chronic pancreatitis. Early complications were observed in 1 (6.3%) patient. Pancreatitis or bleeding related to balloon dilation was not observed. CONCLUSIONS Endoscopic balloon dilation for the minor papilla is feasible for the management of symptomatic pancreas divisum.

Abstract
Over the past decades, the incidence and the number of hospital admissions for acute pancreatitis have increased in the Western countries. The two most common etiological factors of acute pancreatitis are gallstones (including small gallstones or microlithiasis) and alcohol abuse. Acute pancreatitis is associated with a significant mortality (4-10%) and 25% in case of pancreatic necrosis, especially. Edematous pancreatitis is benign and oral feeding can be restarted once abdominal pain is decreasing and inflammatory markers are improving. Enteral tube feeding should be the primary therapy in patients with predicted severe acute pancreatitis who require nutritional support. Enteral nutrition in acute pancreatitis can be administered via either the nasojejunal or nasogastric route. In case of necrosis, preventive antibiotics are not recommended. The single indication is infected necrosis confirmed by fine needle aspiration. The incidence trends of acute pancreatitis possibly reflect a change in the prevalence of main etiological factors (e.g. gallstones and alcohol consumption) and cofactors such as tobacco, obesity and genetic susceptibility. Priority is to search for associated causes, especially in cases with atypical symptoms. In case of first acute pancreatitis in patients older than 50 years, the presence of a tumor (benign or malignant) has to be specifically ruled out, using CT-scan, MRI and endoscopic ultrasound.

Abstract
PURPOSE To investigate the multi-modality imaging presentation of the pancreatic retention cyst (PRC) with pathologic correlation. METHODS Imaging data including CT, MRI, endoscopic ultrasonography (EUS) and EUS guided fine needle aspiration (EUS-FNA), and endoscopic retrograde cholangiopancreatography (ERCP) in fifteen patients (five males and ten females; mean age, 44.5 years) with pathologically proven PRC were analyzed retrospectively, and imaging features were correlated with pathological findings. RESULTS Sixteen PRCs of 15 patients were included in this study. The mean size of PRCs was 4.4 × 4.6 cm (range 0.5 × 0.6-8.1 × 10.1 cm). PRC were round (n = 11), oval (n = 2), or lobular (n = 3). Punctiform calcification of the wall on CT (n = 2), thin septa (n = 4), thin wall (n = 3), and dilation of upstream pancreatic duct (n = 6; mean diameter, 4.3 mm) were detected. Dilation of upstream pancreatic duct was smooth in five PRCs and irregular in one PRC with pancreatic duct with punctiform calcification. Communication of PRCs with pancreatic duct was seen in two patients (one on CT, one on ERCP). Pancreatic inflammation and neoplasm were detected in four and two patients, respectively. CONCLUSIONS PRC typically presents as a well-defined, round cystic lesion, and different associated pathologic conditions including pancreatic inflammation and neoplasm may be detected in some patients on the multi-modality imaging examinations. Smooth dilation of upstream pancreatic duct with uncommon communication to the cyst may be helpful for the differentiation. Combination of a variety of imaging modalities could contribute to improve the diagnosis.

Abstract
Pancreaticobiliary maljunction (PBM) is an unusual anomalous condition in which the pancreatic duct and bile duct merge outside the duodenal wall and form a long common channel. Pancreas divisum (PD) is a congenital anomaly in which the dorsal and ventral pancreatic ducts fail to fuse. Endoscopic retrograde cholangiopancreatography (ERCP) is the gold standard for diagnosing PD and magnetic resonance cholangiopancreatography (MRCP) is the non-invasive choice. In this study, four cases of patients with unusual PBM in addition to PD are described. The patients presented with abdominal pain, which was caused by distal biliary stricture diagnosed by MRCP. The patients received ERCP and had a good prognosis.

Abstract
Some patients with pancreas divisum (PD) develop symptoms of recurrent pancreatitis. This is probably caused by insufficient drainage of the pancreatic duct. Magnetic resonance cholangiopancreatography (MRCP) is a non-invasive test reported to be highly accurate in diagnosing PD. Endoscopic minor papilla sphincterotomy is most effective in the treatment of patients with PD and pancreatic stones. We report a case of 17-year-old boy who has suffered from several abdominal pain attacks throughout his childhood without a specific diagnosis. Radiological findings after the first episode of pancreatitis were typical for PD and led to specific treatment and cure.

Abstract
Mutations in the gene encoding the cystic fibrosis transmembrane regulator (CFTR) have been reported to increase the risk of recurrent acute pancreatitis in patients with pancreas divisum. We assessed the CFTR gene in a young male patient with pancreas divisum and recurrent acute pancreatitis. Magnetic resonance cholangiopancreatography and computed tomography revealed that the patient had pancreas divisum, with an enlarged and tortuous pancreatic duct; he also had positive results from the cystic fibrosis sweat test. Genetic analysis did not identify any common CFTR mutations, but did show that he was homozygous for the 5T allele in intron 8 IVS8 5T-12TG (which affects splicing at intron 8). Endoscopic sphincterotomy and stenting of papilla minor was performed. The IVS8 5T-12TG variant has been associated with abnormal organ development, therefore it is possible that CFTR has an important role in the development of the pancreatic duct. We propose this patient has recurrent acute pancreatitis resulting from a developmental defect associated with a suboptimal CFTR function.

Abstract
BACKGROUND Only one case of santorinicele without pancreas divisum pathophysiology (SWOPP) was previously reported. The purpose of the study was to determine the gross prevalence of SWOPP and santorinicele with pancreas divisum (SWPD) in community and patient populations, and investigate their clinical and radiographic features. METHODS This cross-sectional study was performed at a tertiary referral centre. The Patient group comprised 2035 consecutive patients enrolled in the study who underwent magnetic resonance cholangiopancreatography (MRCP) studies. The Community group comprised 2905 consecutive subjects who participated in our whole-body medical check-up program that routinely includes MRCP studies. SWOPP was diagnosed when a saccular dilatation of the terminal portion of the dorsal pancreatic duct was observed unaccompanied by pancreas divisum or dominant dorsal duct. The prevalence of SWOPP and SWPD, and the clinical and radiological features were assessed in each group. RESULTS Five cases of SWOPP were found in the Patient group (age range, 67-85 years; mean age, 73.6 years) (5/2035 = 0.25%; 95% confidence interval, 0.07-0.57); there were no cases of SWOPP in the Community group (0/2905 = 0.00%; 95% confidence interval, 0.00-0.10) (P = 0.01). Previous history of pancreatitis (4/5) and chronic pancreatitis (3/5) was more common in patients with SWOPP than in other subjects in the Patient or Community groups (both P < 0.05). Two cases of SWOPP were accompanied by reverse-Z type meandering main pancreatic duct. Six cases of SWPD were found. These cases were asymptomatic in 4/6, had a larger santorinicele (6.9 mm) than SWOPP patients (4.5 mm; P = 0.02), and were not associated with pancreatitis (0/6). CONCLUSIONS The second to sixth reported cases of SWOPP were presented. SWOPP is a relatively rare condition found mostly in patients suffering pancreatitis, especially chronic pancreatitis, and may be an acquired condition. Santorinicele is not always accompanied by pancreas divisum.

Abstract
Duodenal duplication cysts are rare congenital anomalies that can cause acute pancreatitis. Pancreas divisum is also a congenital anomaly, often discovered incidentally, but is considered a possible cause of acute pancreatitis. We report the case of the combination of both anomalies causing recurrent episodes of acute pancreatitis in a young man. Endoscopic treatment by partial excision of the cyst with a polypectomy snare and sphincterotomy of the minor papilla was successful.

Abstract
Chronic pancreatitis (CP) is a relatively uncommon, complex and heterogeneous disease. The absence of a gold standard applicable to the initial phases of CP makes its early diagnosis difficult. Some of its complications, particularly chronic pain, can be difficult to manage. There is much variability in the diagnosis and treatment of CP and its complications amongst centers and professionals. The Spanish Pancreatic Club has developed a consensus on the management of CP. Two coordinators chose a multidisciplinary panel of 24 experts on this disease. A list of questions was drafted, and two experts reviewed each question. Then, a draft was produced and shared with the entire panel of experts and discussed in a face-to-face meeting. This first part of the consensus addresses the diagnosis of CP and its complications.

Abstract
Pancreas divisum (PD) and meandering main pancreatic duct (MMPD) are common developmental variants of the pancreatic ductal system. They always appear in the head of the pancreas and are associated with idiopathic pancreatitis. The condition of these variants is rarely reported to have changed after birth. We present a rare case of false PD that occurred with alteration of loop-type MMPD after endoscopic retrograde pancreatography (ERP) and brush cytology followed by post-procedural pancreatitis. A 76-year-old female underwent pre-surgical ERP and brush cytology for an incidentally detected, expanding branch-type intraductal papillary mucinous neoplasm in the body of pancreas. The guidewire was inserted along the main pancreatic duct (MPD) and had uncoiled the loop-shaped MPD into a linear shape; soon afterwards, the patient developed post-procedural acute pancreatitis. Follow-up magnetic resonance cholangiopancreatography study 1 month later revealed the morphology of PD with an absent ventral duct. We hypothesize that inflammatory synechia had occluded the uncoiled ventral duct. This single case provides evidence that pancreatic ductal anatomy is flexible in some situations.

Abstract
Chronic pancreatitis (CP) is widely prevalent in Asian countries much more so in India and Japan. The phenotype of CP is somewhat similar to that reported from western countries. The prevalent types of CP are mainly idiopathic and alcohol related. Current evidence suggests that the term "tropical pancreatitis" used for idiopathic CP from India is a misnomer. Gallstones' association with CP reported from China remains controversial. There has been ample evidence that mutations in the SPNIK1 and CFTR genes are strongly associated with idiopathic CP in patients from different ethnic backgrounds. Oxidative stress is important in the pathophysiology and antioxidants have been shown to result in significant pain relief with CP. Home-made balanced diet is effective for treating malnutrition in patients with CP. Endoscopic therapy combined with ESWL may provide significant relief in patients with pancreatic ductal calculi/stricture. Surgery is quite effective in CP and may be better than endotherapy.

Abstract
Background Meandering main pancreatic duct (MMPD), which comprises loop type and reverse-Z type main pancreatic duct (MPD), has long been discussed its relation to pancreatitis. However, no previous study has investigated its clinical significance. We aimed to determine the non-biased prevalence and the effect of MMPD on idiopathic pancreatitis using non-invasive magnetic resonance (MR) technique. Methods and Findings A cross-sectional study performed in a tertiary referral center. The study enrolled 504 subjects from the community and 30 patients with idiopathic pancreatitis (7 acute, 13 chronic, and 10 recurrent acute). All subjects underwent MR scanning and medical examination. MMPD was diagnosed when the MPD in the head of pancreas formed two or more extrema in the horizontal direction on coronal images of MR cholangiopancreatography, making a loop or a reverse-Z shaped hairpin curves and not accompanied by other pancreatic ductal anomaly. Statistical comparison was made among groups on the rate of MMPD including loop and reverse-Z subtypes, MR findings, and clinical features. The rate of MMPD was significantly higher for all idiopathic pancreatitis/idiopathic recurrent acute pancreatitis (RAP) (20%/40%; P<0.001/0.0001; odds ratio (OR), 11.1/29.0) than in the community (2.2%) but was not higher for acute/chronic pancreatitis (14%/8%; P = 0.154/0.266). Multiple logistic regression analysis revealed MMPD to be a significant factor that induces pancreatitis/RAP (P<0.0001/0.0001; OR, 4.01/26.2). Loop/reverse-Z subtypes were found more frequently in idiopathic RAP subgroup (20%/20%; P = 0.009/0.007; OR, 20.2/24.2) than in the community (1.2%/1.0%). The other clinical and radiographic features were shown not associated with the onset of pancreatitis. Conclusions MMPD is a common anatomical variant and might be a relevant factor to the onset of idiopathic RAP.

Abstract
Bertin et al. partially dispel arguments that pancreas divisum (PD) causes pancreatitis, but fascinatingly indicate that PD associates with CFTR gene mutations predisposing to pancreatitis. This association, however, does not definitely confer a pathophysiological role for PD in pancreatitis but may denote that PD co-mingles with CFTR mutations without influencing pancreatitis or CFTR mutations influence pancreatic duct embryogenesis. We advise "idiopathic pancreatitis" patients with PD to undergo genetic testing. In lieu of CFTR mutations undertake no endoscopic/surgical procedure; if CFTR mutations are found, then refer patients for genetic counseling and withhold endoscopic/surgical therapy unless randomized studies show benefit.

Abstract
Endoscopic ampullectomy is a minimally invasive method of treating superficial lesions of the ampulla of Vater. With careful patient selection and lesion assessment it is a safe and efficacious therapeutic procedure that can obviate the need for potentially major surgical intervention. Strategies for safe and successful endoscopic ampullectomy with a focus on resection technique and recognition and management of complications are presented.
