Revolutionizing the Pancreatic Tumor Diagnosis: Emerging Trends in Imaging Technologies: A Systematic Review. MEDICINA (KAUNAS, LITHUANIA) 2024; 60:695. [PMID: 38792878 PMCID: PMC11122838 DOI: 10.3390/medicina60050695] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/27/2024] [Revised: 04/19/2024] [Accepted: 04/21/2024] [Indexed: 05/26/2024]
Abstract
Background and Objectives: The pancreas, ensconced within the abdominal cavity, requires a plethora of sophisticated imaging modalities for its comprehensive evaluation, with ultrasonography serving as a primary investigative technique. A myriad of pancreatic pathologies, encompassing pancreatic neoplasia and a spectrum of inflammatory diseases, are detectable through these imaging strategies. Nevertheless, the intricate anatomical confluence and the pancreas's deep-seated topography render the visualization and accurate diagnosis of its pathologies a formidable endeavor. The objective of our paper is to review the best diagnostic imagistic tools for the pancreas. Materials and Methods: we have gathered several articles using Prisma guidelines to determine the best imagistic methods. The imperative of pancreatic scanning transcends its diagnostic utility, proving to be a pivotal element in a multitude of clinical specialties, notably surgical oncology. Within this domain, multidetector computed tomography (MDCT) of the pancreas holds the distinction of being the paramount imaging modality, endorsed for its unrivaled capacity to delineate the staging and progression of pancreatic carcinoma. In synergy with MDCT, there has been a notable advent of avant-garde imaging techniques in recent years. These advanced methodologies, including ultrasonography, endoscopic ultrasonography, contrast-enhanced ultrasonography, and magnetic resonance imaging (MRI) conjoined with magnetic resonance cholangiopancreatography (MRCP), have broadened the horizon of tumor characterization, offering unparalleled depth and precision in oncological assessment. Other emerging diagnostic techniques, such as elastography, also hold a lot of potential and promise for the future of pancreatic imaging. Fine needle aspiration (FNA) is a quick, minimally invasive procedure to evaluate lumps using a thin needle to extract tissue for analysis. It is less invasive than surgical biopsies and usually performed as an outpatient with quick recovery. Its accuracy depends on sample quality, and the risks include minimal bleeding or discomfort. Results, guiding further treatment, are typically available within a week. Elastography is a non-invasive medical imaging technique that maps the elastic properties and stiffness of soft tissue. This method, often used in conjunction with ultrasound or MRI, helps differentiate between hard and soft areas in tissue, providing valuable diagnostic information. It is particularly useful for assessing liver fibrosis, thyroid nodules, breast lumps, and musculoskeletal conditions. The technique is painless and involves applying gentle pressure to the area being examined. The resulting images show tissue stiffness, indicating potential abnormalities. Elastography is advantageous for its ability to detect diseases in early stages and monitor treatment effectiveness. The procedure is quick, safe, and requires no special preparation, with results typically available immediately. Results: The assembled and gathered data shows the efficacy of various techniques in discerning the nature and extent of neoplastic lesions within the pancreas. Conclusions: The most common imaging modalities currently used in diagnosing pancreatic neoplasms are multidetector computed tomography (MDCT), endoscopic ultrasound (EUS), and magnetic resonance imaging (MRI), alongside new technologies, such as elastography.

Abstract
Chronic pancreatitis is commonly associated with heavy alcohol use and cigarette smoking, though many cases of chronic pancreatitis are idiopathic. Energy drink consumption has been on the rise over the last decade, with an adverse health risk profile including gastrointestinal symptoms such as dyspepsia, reflux, and gastritis. There have been several case reports linking energy drink consumption to presentations of acute pancreatitis in adult patients. To our knowledge, the association between energy drinks and episodes of chronic pancreatitis flares has not been well studied. This article explores a case of chronic pancreatitis pain related to excessive energy drink consumption in an adult male patient. This study aims to shed light on energy drinks as a potential etiology of chronic pancreatitis flares, and emphasizes the importance of counseling patients on the potential risks of excessive energy drink consumption.

Abstract
Chronic pancreatitis is one of the most challenging disorders from the perspective of its early diagnosis and effective treatment. Within the last decade, the diagnosis of early chronic pancreatitis has been firmly introduced into the practice of gastroenterology. The delineation of this form as an initial stage of chronic pancreatitis is based on the need in early and effective treatment that could cease the progression of the disease and reduce the possibility of its complications.
The diagnostic criteria of chronic pancreatitis have been described in details in the literature; however, specifics of the diagnosis in its early stage have been scarcely highlighted. Chronic pancreatitis is commonly diagnosed with a number of imaging techniques (they can show abnormalities in morphology of the pancreas), as well as laboratory tests (showing functional organ deficit). However, morphological and imaging techniques are insufficient for the diagnosis of the early chronic pancreatitis. A new integral strategy towards early diagnosis seems necessary, that would consider not only the morphology, but also potential etiology, risk factors of the disease and its complications in patients with suspected chronic pancreatitis.
The review of the literature presents the definition of the early pancreatitis and discusses the potential of imaging techniques and functional tests in its diagnosis. An adequate strategy for the diagnosis of the early pancreatitis is formulated, based on an individual patient characteristic with suspected early chronic pancreatitis, namely, risk factors, clinical manifestations, imaging results and serological biomarkers.

Abstract
BACKGROUND Chronic pancreatitis (CP) is a long-lasting disease frequently associated with complications for which there is no comprehensive pathophysiological classification.
AIM The aims of this study were to: Propose a pathophysiological classification of the complications of CP; evaluate their prevalence in a surgical cohort prior to, and following surgical management; and assess the impact of the surgical treatment on the occurrence of new complications of CP during follow-up. We hypothesized that optimal surgical treatment can resolve existing complications and reduce the risk of new complications, with the exclusion of pancreatic insufficiency. The primary outcomes were prevalence of complications of CP at baseline (prior to surgical treatment) and occurrence of new complications during follow-up.
METHODS After institutional review board approval, a prospective observational cohort study with long-term follow-up (up to 20.4 years) was conducted. All consecutive single-center adult patients (≥ 18 years of age) with CP according to the criteria of the American Pancreas Association subjected to surgical management between 1997 and 2021, were included. The prevalence of CP complications evaluated, according to the proposed classification, in a surgical cohort of 166 patients. Development of the pathophysiological classification was based on a literature review on the clinical presentation, course, and complications of CP, as well a review of previous classification systems of CP.
RESULTS We distinguished four groups of complications: Pancreatic duct complications, peripancreatic complications, pancreatic hemorrhages, and pancreatic insufficiency (exocrine and endocrine). Their baseline prevalence was 20.5%, 23.5%, 10.2%, 31.3%, and 27.1%, respectively. Surgical treatment was highly effective in avoiding new complications in the first and third groups. In the group of peripancreatic complications, the 15-year Kaplan-Meier prevalence of new complications was 12.1%. The prevalence of pancreatic exocrine and endocrine insufficiency increased during follow-up, being 66.4% and 47.1%, respectively, at 15 years following surgery. Pancreatoduodenal resection resulted optimal results in avoiding new peripancreatic complications, but was associated with the highest rate of pancreatic exocrine insufficiency.
CONCLUSION The proposed complication classification improves the understanding of CP. It could be beneficial for clinical decision making, as it provides an opportunity for more comprehensive judgement on patient’s needs on the one hand, and on the pros and cons of the treatment under consideration, on the other. The presence of complications of CP and the risk of development of new ones should be among the main determinants of surgical choice.

Abstract
INTRODUCTION Despite evidence-based guidelines, exocrine pancreatic insufficiency is frequently underdiagnosed and undertreated in patients with chronic pancreatitis. Therefore, the aim of this study is to provide insight into the current opinion and clinical decision-making of international pancreatologists regarding the management of exocrine pancreatic insufficiency. METHODS An online survey and case vignette study was sent to experts in chronic pancreatitis and members of various pancreatic associations: EPC, E-AHPBA and DPSG. Experts were selected based on publication record from the past 5 years. RESULTS Overall, 252 pancreatologists participated of whom 44% had ≥ 15 years of experience and 35% treated ≥ 50 patients with chronic pancreatitis per year. Screening for exocrine pancreatic insufficiency as part of the diagnostic work-up for chronic pancreatitis is performed by 69% and repeated annually by 21%. About 74% considers nutritional assessment to be part of the standard work-up. Patients are most frequently screened for deficiencies of calcium (47%), iron (42%), vitamin D (61%) and albumin (59%). In case of clinically steatorrhea, 71% prescribes enzyme supplementation. Of all pancreatologists, 40% refers more than half of their patients to a dietician. Despite existing guidelines, 97% supports the need for more specific and tailored instructions regarding the management of exocrine pancreatic insufficiency. CONCLUSION This survey identified a lack of consensus and substantial practice variation among international pancreatologists regarding guidelines pertaining the management of exocrine pancreatic insufficiency. These results highlight the need for further adaptation of these guidelines according to current expert opinion and the level of available scientific evidence.

Abstract
Purpose Computed tomography (CT) is the most used imaging modality for diagnosing chronic pancreatitis (CP), but advances in transabdominal ultrasound (US) technology have given US a position as a viable alternative. We aimed to evaluate the diagnostic accuracy of abdominal CT and pancreatic US compared to the reference standard, a modified Mayo score. Materials and Methods CT, US, and endoscopic ultrasound (EUS) were performed in patients referred due to suspected CP. The modified Mayo score included EUS results, clinical presentation, and results from exocrine and endocrine pancreatic function tests. We scored CT findings according to the modified Cambridge classification and US findings according to the Rosemont classification. Results In total, 73 patients were included. 53 patients (73%) were categorized as CP and 20 (27%) as non-CP. CT and US yielded similar sensitivities (68% and 64%, respectively) and specificities (75 and 85%, respectively) and similar areas under the receiver operating characteristic curves for diagnosing CP. We found no significant differences between the areas under the receiver operating characteristic curves (AUROCs) for CT (AUROC 0.75, 95% CI 0.63-0.87) and US (AUROC 0.81, 95% CI 0.71-0.91). Conclusion We conclude that CT and US had comparable, moderate accuracy in diagnosing CP. Neither modality had high enough sensitivity to exclude the diagnosis as a standalone method.

Abstract
BACKGROUND Both, acute and chronic pancreatitis represent complex disease patterns, whose effective treatment is based on structured diagnostics and therapy by a multi-professional team. There are different systems for an improved objectivity in the classification of the severity of the disease OBJECTIVES: Overview of the common classifications of acute and chronic pancreatitis. MATERIALS AND METHODS Literature research of currently used classifications of acute and chronic pancreatitis. Evaluation of the current chronic pancreatitis guideline. RESULTS For acute pancreatitis, the modified Atlanta Classification and the "determinant-based" classification are most widely used. These classifications are complemented by clinical risk scores such as the Marshall Score and the SOFA Score. In chronic pancreatitis, the image-based Cambridge classification was established. For clinical assessment further classifications such as the ABC classification and the M‑ANNHEIM classification are applied evaluating leading symptoms such as pain, exocrine and endocrine pancreatic insufficiency.

Abstract
Chronic pancreatitis (CP) should be suspected in the case of recurrent upper abdominal pain of unknown origin and/or clinical signs of exocrine pancreatic insufficiency (EPI). Alcohol is the most common etiological factor associated with CP, others being smoking, male gender, and hereditary forms. CP is often associated with recurrent episodes of acute exacerbations.As of today, there is no accepted clinical definition of CP. However, irreversible morphological changes within the pancreas often occur, including dilatation of the main and branch pancreatic ducts, calcifications in ducts and parenchyma, parenchymal atrophy, and development of pseudocysts, though less so in the early phase of CP.

Abstract
Chronic pancreatitis is a complex chronic inflammatory condition that results in pancreas fibrosis and calcification with subsequent exocrine and endocrine insufficiency. Alcohol and nicotine are the most prevalent risk factors, however, recent studies have increasingly discovered genetic associations that increase the risk to develop chronic pancreatitis. Here, we discuss different etiologies of the disease including autoimmune pancreatitis, and present evidence-based diagnostic and therapeutic approaches. In particular, we highlight the interdisciplinary and interventional management of local complications such as pseudocysts, pancreatic duct stones, biliary duct and pancreatic duct stenosis and persistent pain.

Abstract
Abdominal pain, diarrhea with weight loss, and endocrine insufficiency represent the dominant symptoms of chronic pancreatitis (CP). High intensity of pain and constant pain have been shown to reduce quality of life in CP and may result in disability and increased health resource utilization. Various basic challenges and unanswered questions still exist regarding the treatment of pain in CP. Recently, limited evidence has been gained that early surgery for painful disease might be associated with better treatment results. Thus, timing of pancreatic surgery in painful disease represents a major issue that needs to be clarified in future studies. In this context, surveillance of patients is necessary in clinical practice. It appears that a generally accepted classification of the disease represents a major requirement for inter-institutional comparison of data with future progress in clinical research. Among recently proposed classification systems, the M-ANNHEIM classification system of CP with its recently presented M-ANNHEIM Surgery Score might be a useful tool to picture the course of the disease and to monitor treatment results. Future research is required to clarify the possible role of this system in the management of pain in CP. In the present article, we provide an overview of current status, challenges, and unanswered questions in the treatment of pain in CP, and we demonstrate the potential benefits of the M-ANNHEIM classification system in the management of painful CP.

Abstract
Pancreatitis, in both acute and chronic forms, poses a major therapeutic challenge and is associated with great morbidity and several complications. The nature of pancreatic injury in chronic pancreatitis (CP) and the wide range of causative processes that lead to CP have made effective therapy a true unmet need. Multiple physiological, genetic, environmental, and behavioral factors contribute to the development of CP. As a result, several fields of research are aimed at identifying and addressing the factors that contribute to pancreatic injury. In this article, we review the current understanding of the pathogenesis and natural history of CP. We focus on the autonomous nervous system, immune system, and role of a chronobiological therapeutic approach to alleviate symptoms and prevent or reverse pancreatic injury associated with CP. We aim to demonstrate that individualizing chronopharmacological treatments for CP is a promising direction for future treatment using immune, nervous, and circadian systems.

Abstract
Background Oxalate nephropathy is a potentially underestimated cause of kidney failure characterized by massive deposition of calcium oxalate crystals in the renal parenchyma. The prevalence and modes of presentation of this entity are ill-defined. Methods Here we report on the largest consecutive series of cases of adult oxalate nephropathy diagnosed on native kidney biopsies from January 2010 to December 2018 in the UCLouvain Kidney Disease Network. Results We screened 2265 native kidney biopsies and identified 22 cases (1%) of oxalate nephropathy. Patients had a mean age at diagnosis of 61 years (±20) and presented either with acute on chronic kidney disease (CKD) (62%) or with acute kidney injury (AKI) (38%). Mean serum creatinine at biopsy was 8.0 ± 4.5 mg/dl. Kidney biopsies showed abundant calcium oxalate crystal deposits, associated with acute interstitial nephritis and tubular necrosis, and variable degrees of interstitial fibrosis and tubular atrophy. Chronic pancreatitis and gastric bypass were the most common causes of oxalate nephropathy (48%). During a mean follow-up of 29 months, half of the patients (52%) progressed to kidney failure, all within the month following diagnosis. Higher serum creatinine level at presentation and interstitial fibrosis and tubular atrophy score were associated with progression to kidney failure. Conclusion Oxalate nephropathy is the cause of kidney disease in 1% of consecutive native kidney biopsies and typically presents as acute on CKD or AKI. The prognosis of the disease is poor, with a high rate of kidney failure within the first month after the diagnosis.

Abstract
Background It is clinically necessary to validate a new non-invasive and reliable imaging method to detect early chronic pancreatitis. Intravoxel incoherent motion magnetic resonance imaging (MRI) is useful for quantitative assessment in abdominal solid organs. Purpose To investigate the usefulness of intravoxel incoherent motion MRI parameters in the diagnosis of chronic pancreatitis. Material and Methods Sixty patients with early chronic pancreatitis (n = 44) and chronic pancreatitis (n = 16) were assessed with intravoxel incoherent motion imaging. For comparison, a control group of 71 individuals without chronic pancreatitis was also enrolled. The perfusion fraction (f), pseudo-diffusion coefficient (D*), true diffusion coefficient (D), and apparent diffusion coefficient of pancreatic parenchyma were calculated. These measurements were compared between the three groups. The diagnostic accuracy of imaging parameters was assessed. Results The f values of the early chronic pancreatitis group and the chronic pancreatitis group were significantly lower than those of the control group ( P < 0.001 and P < 0.001, respectively). The D* value of the chronic pancreatitis group was significantly lower than that of the early chronic pancreatitis group ( P = 0.0025). The D values of the early chronic pancreatitis group and the chronic pancreatitis group were significantly higher than those of the control group ( P = 0.001 and P = 0.001, respectively). The perfusion fraction showed the highest diagnostic performance with an Az value of 0.76 for discriminating the control group from the early chronic pancreatitis and chronic pancreatitis groups. Conclusion Intravoxel incoherent motion MRI parameters may reflect the minimal histological changes in early chronic pancreatitis.

Abstract
PURPOSE There is an unmet need for new systems with quantitative pancreatic imaging assessments to support better diagnosis and understand development of chronic pancreatitis (CP). The aims were to present such an approach for assessment of imaging features in CP, to apply this system in a multi-center cohort of CP patients (feasibility study), and to report inter-reader agreement between expert radiologists (validation study). METHODS The feasibility study included pancreatic computed tomography (CT) or magnetic resonance imaging (MRI) from 496 patients with definitive CP in the Scandinavian Baltic Pancreatic Club (SBPC) database. Images were assessed according to the new SBPC imaging system (quantitative assessments of ductal and parenchymal features). Inter-reader agreement of reported imaging parameters was investigated for 80 CT and 80 MRI examinations by two expert radiologists. RESULTS Reporting of the imaging features into the imaging system was deemed feasible for > 80% of CT and > 90% of MRI examinations. Quantitative assessments of main pancreatic duct diameters, presence/number/diameter of calcifications, and gland diameters had high levels of inter-reader agreement with κ-values of 0.75-0.87 and intraclass correlation coefficients of 0.74-0.97. The more subjective assessments, e.g., irregular main pancreatic duct and dilated side-ducts, had poor to moderate agreement with κ-values of 0.03-0.44. CONCLUSION The presented system provides a feasible mean for systematic assessment of CP imaging features. Imaging parameters based on quantitative assessment, as opposed to subjective assessments, have better reproducibility and should be preferred in the development of new grading systems for understanding pathophysiology and disease progression in CP.

Abstract
OBJECTIVES The pancreatic burnout hypothesis postulated an increasing absence of pain with simultaneous functional insufficiency in advanced stages of chronic pancreatitis (CP). However, the underlying data remain scarce and contradictory. We aimed to analyze, first, the frequency of a pancreatic burnout in CP, and, second, its association with etiological risk factors. METHODS We performed a multicenter, retrospective, cross-sectional study with 741 patients with CP categorized according to the M-ANNHEIM classification. Pancreatic burnout was defined by different combinations of exocrine or endocrine insufficiency with partial or complete absence of abdominal pain. RESULTS The frequency of a pancreatic burnout increased with prolonged disease duration and was observed in a maximum of 38% of patients after 20 years. Development of a pancreatic burnout was significantly associated with alcohol consumption (P < 0.05, Mann-Whitney U test), but not with other etiological risk factors. After a disease duration of more than 10 years, the likelihood of a burnout was 8 times higher in alcoholic CP than in nonalcoholic CP (95% confidence interval, 1.5-42.0; P = 0.015, logistic regression analysis). CONCLUSIONS A pancreatic burnout does not regularly occur in CP. Increased burnout rates are only observed in patients with alcoholic CP.

Abstract
AIM To assess the use of ERAS in laparoscopic Frey procedure. MATERIAL AND METHODS From August 2012 to November 2017 laparoscopic Frey procedure were performed in 35 patients. Fully laparoscopic were performed 31 (88.5%) procedures. We use fast-track protocol from 13 patients. We included from statistic analyses patients where procedure was changed or was conversion or was simultaneous procedure. The total number of patients analyzed was 27. The patients were divided into two groups: I - before the fast-track protocol (n=11), II - after the protocol implementation (n=16). RESULTS The operating time was 460 (365-530) minutes in I group and 420 (295-540) minutes in II group. Blood loss was 150 (5-300) and 150 (40-700) ml. The median postoperative stay period was 10 (5-25) days and 6.5 (3-11) days (p=0.007). CONCLUSION The combination of laparoscopic technologies and fast-track protocol reduces the duration of the postoperative stay period.

Abstract
The lack of effective therapeutic agents specifically tailored for chronic pancreatitis (CP) has hampered clinical care and negatively impacted patients' lives. New mechanistic insights now point to novel therapies, which involve both recently developed and/or repurposed agents. This working group focused on 2 main outcomes for CP: pain and progression of disease. The goal is to frame the essential aspects of trial design including patient-centered outcomes, proposed methods to measure the outcomes of pain and progression, and study design considerations for future trials to facilitate rapid drug development for patients with CP.

Abstract
Diagnosis of chronic pancreatitis requires a complete medical history and clinical investigations, including imaging technologies and function tests. MR imaging/magnetic resonance cholangiopancreatography is the preferred diagnostic tool for detection of ductal and parenchymal changes in patients with chronic pancreatitis. Ductal changes may not be present in the initial phase of chronic pancreatitis. Therefore, early diagnosis remains challenging.

Abstract
The paper presents the international guidelines for imaging evaluation of chronic pancreatitis. The following consensus was obtained: Computed tomography (CT) is often the most appropriate initial imaging modality for evaluation of patients with suspected chronic pancreatitis (CP) depicting most changes in pancreatic morphology. CT is also indicated to exclude other potential intraabdominal pathologies presenting with symptoms similar to CP. However, CT cannot exclude a diagnosis of CP nor can it be used to exclusively diagnose early or mild disease. Here magnetic resonance imaging (MRI) and MR cholangiopancreatography (MRCP) is superior and is indicated especially in patients where no specific pathological changes are seen on CT. Secretin-stimulated MRCP is more accurate than standard MRCP in the depiction of subtle ductal changes. It should be performed after a negative MRCP, when there is still clinical suspicion of CP. Endoscopic ultrasound (EUS) can also be used to diagnose parenchymal and ductal changes mainly during the early stage of the disease. No validated radiological severity scoring systems for CP are available, although a modified Cambridge Classification has been used for MRCP. There is an unmet need for development of a new and validated radiological CP severity scoring system based on imaging criteria including glandular volume loss, ductal changes, parenchymal calcifications and parenchymal fibrosis based on CT and/or MRI. Secretin-stimulated MRCP in addition, can provide assessment of exocrine function and ductal compliance. An algorithm is presented, where these imaging parameters can be incorporated together with clinical findings in the classification and severity grading of CP.

Abstract
BACKGROUND & OBJECTIVES Autoimmune pancreatitis (AiP) is treated by immunosuppressive therapy. Exact description of disease activity of AiP is essential in clinical practice and research, but a score to describe the disease activity is missing. Thus, we aimed to establish an activity score of AiP. METHODS We retrospectively studied long-term disease courses of 29 patients with AiP (Mannheim, Germany), receiving corticosteroid treatment (CST) by analyzing 613 treatment appointments. Two assumptions were made: First, disease activity is higher at emergency treatments; second, disease activity drops under CST. In all patients, we evaluated established activity- and classification-systems of chronic pancreatitis (cP). Based on the most suitable system, we established an activity score of AiP by including AiP-specific parameters identified from our long-term disease courses and the literature. The new AiP-specific activity score was validated in an external cohort of 14 patients with AiP (Stockholm, Sweden). RESULTS Within published activity indexes of cP, the M-ANNHEIM-classification most significantly correlated with emergency- and treatment-dependent disease activities (p < 0.001 and p < 0.01, conditional-logistic-regression-analysis). Significant correlations of disease activity were found for several clinical parameters (biliary involvement, extrapancreatic lesions, acute pancreatitis, focal pancreatic mass, pancreatic sausage/mass, focal enlargement, ascites; p < 0.05, Wilcoxon-signed-rank-test). Based on these data and disease features from the literature, the M-ANNHEIM-AiP-Activity-Score (MAAS) was established. CST-induced reduction of MAAS disease activity of more than 60% was associated with lower relapse rates (p < 0.05; Chi-Square-test). The results were validated in the external patient cohort. CONCLUSION The MAAS might represent a useful tool to monitor AiP.

Development and Validation of a Chronic Pancreatitis Prognosis Score in 2 Independent Cohorts. Gastroenterology 2017; 153:1544-1554.e2. [PMID: 28918191 DOI: 10.1053/j.gastro.2017.08.073] [Citation(s) in RCA: 33] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/26/2017] [Revised: 08/22/2017] [Accepted: 08/24/2017] [Indexed: 12/17/2022]
Abstract
BACKGROUND & AIMS The clinical course of chronic pancreatitis is unpredictable. There is no model to assess disease severity or progression or predict patient outcomes. METHODS We performed a prospective study of 91 patients with chronic pancreatitis; data were collected from patients seen at academic centers in Europe from January 2011 through April 2014. We analyzed correlations between clinical, laboratory, and imaging data with number of hospital readmissions and in-hospital days over the next 12 months; the parameters with the highest degree of correlation were used to develop a 3-stage chronic pancreatitis prognosis score (COPPS). The predictive strength was validated in 129 independent subjects identified from 2 prospective databases. RESULTS The mean number of hospital admissions was 1.9 (95% confidence interval [CI], 1.39-2.44) and 15.2 for hospital days (95% CI, 10.76-19.71) for the development cohort and 10.9 for the validation cohort (95% CI, 7.54-14.30) (P = .08). Based on bivariate correlations, pain (numeric rating scale), level of glycated hemoglobin A1c, level of C-reactive protein, body mass index, and platelet count were used to develop the COPPS system. The patients' median COPPS was 8.9 points (range, 5-14). The system accurately discriminated stages of disease severity (low to high): A (5-6 points), B (7-9), and C (10-15). In Pearson correlation analysis of the development cohort, the COPPS correlated with hospital admissions (0.39; P < .01) and number of hospital days (0.33; P < .01). The correlation was validated in the validation set (Pearson correlation values of 0.36 and 0.44; P < .01). COPPS did not correlate with results from the Cambridge classification system. CONCLUSIONS We developed and validated an easy to use dynamic multivariate scoring system, similar to the Child-Pugh-Score for liver cirrhosis. The COPPS allows objective monitoring of patients with chronic pancreatitis, determining risk for readmission to hospital and potential length of hospital stay.

Abstract
AIM To compare two tests for exocrine pancreatic function (EPF) for use in M-ANNHEIM staging for pancreatitis. METHODS One hundred and ninety four consecutive patients with acute pancreatitis (AP; n = 13), recurrent acute pancreatitis (RAP; n = 65) and chronic pancreatitis (CP; n = 116) were enrolled. EPF was assessed by faecal elastase-1 (FE-1) estimation and stool fat excretion by the acid steatocrit method. Patients were classified as per M-ANNHEIM stages separately based on the results of the two tests for comparison. Independent Student's t-test, χ2 test, Kruskal-Wallis test, Mann-Whitney U test and McNemar's test were used as appropriate. RESULTS Sixty-one (52.5%) patients with CP had steatorrhoea when assessed by the acid steatocrit method; 79 (68.1%) with CP had exocrine insufficiency by the FE-1 test (χ2 test, P < 0.001). The results of acid steatocrit and FE-1 showed a significant negative correlation (Spearman's rho = -0.376, P < 0.001). A statistically significant difference was seen between the M-ANNHEIM stages as classified separately by acid steatocrit and the FE-1. Thirteen (6.7%), 87 (44.8%), 89 (45.8%) and 5 (2.5%) patients were placed in M-ANNHEIM stages 0, I, II, and III respectively, with the use of acid steatocrit as against 13 (6.7%), 85 (43.8%), 75 (38.6%), and 21 (10.8%) respectively by FE-1 in stages 0, I, II, and III thereby altering the stage in 28 (14.4%) patients (P < 0.001, McNemar's test). CONCLUSION FE-1 estimation performed better than the acid steatocrit test for use in the staging of pancreatitis by the M-ANNHEIM classification since it diagnosed a higher proportion of patients with exocrine insufficiency.

Abstract
BACKGROUND The aim of the study was to evaluate the current opinion and clinical decision-making process of international pancreatologists, and to systematically identify key study questions regarding the diagnosis and treatment of chronic pancreatitis (CP) for future research. METHODS An online survey, including questions regarding the diagnosis and treatment of CP and several controversial clinical case vignettes, was send by e-mail to members of various international pancreatic associations: IHPBA, APA, EPC, ESGE and DPSG. RESULTS A total of 288 pancreatologists, 56% surgeons and 44% gastroenterologists, from at least 47 countries, participated in the survey. About half (48%) of the specialists used a classification tool for the diagnosis of CP, including the Mayo Clinic (28%), Mannheim (25%), or Büchler (25%) tools. Overall, CT was the preferred imaging modality for evaluation of an enlarged pancreatic head (59%), pseudocyst (55%), calcifications (75%), and peripancreatic fat infiltration (68%). MRI was preferred for assessment of main pancreatic duct (MPD) abnormalities (60%). Total pancreatectomy with auto-islet transplantation was the preferred treatment in patients with parenchymal calcifications without MPD abnormalities and in patients with refractory pain despite maximal medical, endoscopic, and surgical treatment. In patients with an enlarged pancreatic head, 58% preferred initial surgery (PPPD) versus 42% initial endoscopy. In patients with a dilated MPD and intraductal stones 56% preferred initial endoscopic ± ESWL treatment and 29% preferred initial surgical treatment. CONCLUSION Worldwide, clinical decision-making in CP is largely based on local expertise, beliefs and disbeliefs. Further development of evidence-based guidelines based on well designed (randomized) studies is strongly encouraged.

Abstract
OBJECTIVES This study aims to compare the M-ANNHEIM, Büchler, and Lüneburg diagnostic tools for chronic pancreatitis (CP). METHODS A cross-sectional analysis of the development of CP was performed in a prospectively collected multicenter cohort including 669 patients after a first episode of acute pancreatitis. We compared the individual components of the M-ANNHEIM, Büchler, and Lüneburg tools, the agreement between tools, and estimated diagnostic accuracy using Bayesian latent-class analysis. RESULTS A total of 669 patients with acute pancreatitis followed-up for a median period of 57 (interquartile range, 42-70) months were included. Chronic pancreatitis was diagnosed in 50 patients (7%), 59 patients (9%), and 61 patients (9%) by the M-ANNHEIM, Lüneburg, and Büchler tools, respectively. The overall agreement between these tools was substantial (κ = 0.75). Differences between the tools regarding the following criteria led to significant changes in the total number of diagnoses of CP: abdominal pain, recurrent pancreatitis, moderate to marked ductal lesions, endocrine and exocrine insufficiency, pancreatic calcifications, and pancreatic pseudocysts. The Büchler tool had the highest sensitivity (94%), followed by the M-ANNHEIM (87%), and finally the Lüneburg tool (81%). CONCLUSIONS Differences between diagnostic tools for CP are mainly attributed to presence of clinical symptoms, endocrine insufficiency, and certain morphological complications.

Abstract
Chronic pancreatitis is defined as a pathological fibro-inflammatory syndrome of the pancreas in individuals with genetic, environmental and/or other risk factors who develop persistent pathological responses to parenchymal injury or stress. Potential causes can include toxic factors (such as alcohol or smoking), metabolic abnormalities, idiopathic mechanisms, genetics, autoimmune responses and obstructive mechanisms. The pathophysiology of chronic pancreatitis is fairly complex and includes acinar cell injury, acinar stress responses, duct dysfunction, persistent or altered inflammation, and/or neuro-immune crosstalk, but these mechanisms are not completely understood. Chronic pancreatitis is characterized by ongoing inflammation of the pancreas that results in progressive loss of the endocrine and exocrine compartment owing to atrophy and/or replacement with fibrotic tissue. Functional consequences include recurrent or constant abdominal pain, diabetes mellitus (endocrine insufficiency) and maldigestion (exocrine insufficiency). Diagnosing early-stage chronic pancreatitis is challenging as changes are subtle, ill-defined and overlap those of other disorders. Later stages are characterized by variable fibrosis and calcification of the pancreatic parenchyma; dilatation, distortion and stricturing of the pancreatic ducts; pseudocysts; intrapancreatic bile duct stricturing; narrowing of the duodenum; and superior mesenteric, portal and/or splenic vein thrombosis. Treatment options comprise medical, radiological, endoscopic and surgical interventions, but evidence-based approaches are limited. This Primer highlights the major progress that has been made in understanding the pathophysiology, presentation, prevalence and management of chronic pancreatitis and its complications.

Abstract
Chronic pancreatitis may lead to steatorrhea, enteric hyperoxaluria, and kidney damage. However, the prevalence and determinants of hyperoxaluria in chronic pancreatitis patients as well as its association with renal function decline have not been investigated.We performed an observational study. Urine oxalate to creatinine ratio was assessed on 2 independent random urine samples in consecutive adult patients with chronic pancreatitis followed at the outpatient clinic from March 1 to October 31, 2012. Baseline characteristics and annual estimated glomerular filtration rate (eGFR) change during follow-up were compared between patients with hyper- and normo-oxaluria.A total of 48 patients with chronic pancreatitis were included. The etiology of the disease was toxic (52%), idiopathic (27%), obstructive (11%), autoimmune (6%), or genetic (4%). Hyperoxaluria (defined as urine oxalate to creatinine ratio >32 mg/g) was found in 23% of patients. Multivariate regression analysis identified clinical steatorrhea, high fecal acid steatocrit, and pancreatic atrophy as independent predictors of hyperoxaluria. Taken together, a combination of clinical steatorrhea, steatocrit level >31%, and pancreatic atrophy was associated with a positive predictive value of 100% for hyperoxaluria. On the contrary, none of the patients with a fecal elastase-1 level >100 μg/g had hyperoxaluria. Longitudinal evolution of eGFR was available in 71% of the patients, with a mean follow-up of 904 days. After adjustment for established determinants of renal function decline (gender, diabetes, bicarbonate level, baseline eGFR, and proteinuria), a urine oxalate to creatinine ratio >32 mg/g was associated with a higher risk of eGFR decline.Hyperoxaluria is highly prevalent in patients with chronic pancreatitis and associated with faster decline in renal function. A high urine oxalate to creatinine ratio in patients with chronic pancreatitis is best predicted by clinical steatorrhea, a high acid steatocrit, and pancreatic atrophy. Further studies will need to investigate the mechanisms of renal damage in chronic pancreatitis and the potential benefits of therapies reducing oxaluria.

Abstract
Introduction Chronic pancreatitis is an inflammatory disease associated with structural and functional damage to the pancreas, causing pain, maldigestion and weight loss and thus worsening the quality of life. Aims and methods Our aim was to find correlations from a multicentre database representing the epidemiological traits, diagnosis and treatment of the disease in Hungary. The Hungarian Pancreatic Study Group collected data prospectively from 2012 to 2014 on patients suffering from chronic pancreatitis. Statistical analysis was performed on different questions. Results Data on 229 patients (74% male and 26% female) were uploaded from 14 centres. Daily alcohol consumption was present in the aetiology of 56% of the patients. 66% of the patients were previously treated for acute exacerbation. One third of the patients had had previous endoscopic or surgical interventions. Pain was present in 69% of the cases, endocrine insufficiency in 33%, diarrhoea in 13% and weight loss in 39%. Diagnosis was confirmed with US (80%), CT scan (52%), MRI-MRCP (6%), ERCP (39%), and EUS (7,4%). A functional test was carried out in 5% of the patients. In 31% of the cases, an endoscopic intervention was performed with the need for re-intervention in 5%. Further elective surgical intervention was necessitated in 44% of endoscopies. 20% of the registered patients were primarily treated with surgery. The biliary complication rate for surgery was significantly smaller (2%) than endoscopy (27%); however, pancreatic complications were higher in the patients treated with surgery. Patients who smoked regularly needed significantly more surgical intervention following endoscopy (66.7% vs. 26.9%, p = 0.002) than non-smokers, and the ratio of surgical intervention alone was also significantly higher (27.3% vs. 10.8%, p = 0.004). The ratio of surgery in patients who smoked and drank was significantly higher (30.09% vs. 12.5%, p = 0.012) than in abstinent and non-smoking patients, similarly to the need for further surgical intervention after endoscopic treatment (71.43% vs. 27.78%, p = 0.004). Conclusions According to the data analysed, the epidemiological data and the aetiological factors in our cohort differ little from European trends. The study highlighted the overuse of ERCP as a diagnostic modality and the low ratio of use of endoscopic ultrasonography. The results proved that alcohol consumption and smoking represent risk factors for the increased need for surgical intervention. Chronic pancreatitis should be treated by multidisciplinary consensus grounded in evidence-based medicine.

Abstract
PURPOSE To determine if T1-weighted MR signal of the pancreas can be used to detect early CP. METHODS A retrospective analysis was performed on 51 suspected CP patients, who had both secretin-enhanced magnetic resonance cholangiopancreatography (S-MRCP) and an intraductal secretin stimulation test (IDST). There were 29 patients in normal and 22 patients in the low bicarbonate group. Bicarbonate level, total pancreatic juice volume, and excretory flow rate were recorded during IDST. Signal intensity ratio of pancreas (SIR), fat signal fraction, pancreatograms findings, and grade of duodenal filling were recorded on S-MRCP by two blinded radiologists. RESULTS There was a significant difference in the signal intensity ratio of the pancreas to spleen (SIRp/s) between the normal and low bicarbonate groups (p < 0.0001). A significant positive correlation was found between pancreatic fluid bicarbonate level and SIRp/s (p < 0.0001). SIRp/s of 1.2 yielded sensitivity of 77% and specificity of 83% for detection of pancreatic exocrine dysfunction (AUC: 0.89). CONCLUSION T1-weighted MR signal of the pancreas has a high sensitivity and specificity for the detection of parenchymal abnormalities related to exocrine dysfunction and can therefore be helpful in evaluation of suspected early CP.

Abstract
OBJECTIVES Obtain summary estimates of sensitivity and specificity for imaging modalities for chronic pancreatitis (CP) assessment. METHODS A systematic search was performed in Cochrane Library, MEDLINE, Embase and CINAHL databases for studies evaluating imaging modalities for the diagnosis of CP up to September 2016. A bivariate random-effects modeling was used to obtain summary estimates of sensitivity and specificity. RESULTS We included 43 studies evaluating 3460 patients. Sensitivity of endoscopic retrograde cholangiopancreatography (ERCP) (82%; 95%CI: 76%-87%) was significant higher than that of abdominal ultrasonography (US) (67%; 95%CI: 53%-78%; P=0.018). The sensitivity estimates of endoscopic ultrasonography (EUS), magnetic resonance imaging (MRI), and computed tomography (CT) were 81% (95%CI: 70%-89%), 78% (95%CI: 69%-85%), and 75% (95%CI: 66%-83%), respectively, and did not differ significantly from each other. Estimates of specificity were comparable for EUS (90%; 95%CI: 82%-95%), ERCP (94%; 95%CI: 87%-98%), CT (91%; 95% CI: 81%-96%), MRI (96%; 95%CI: 90%-98%), and US (98%; 95%CI: 89%-100%). CONCLUSIONS EUS, ERCP, MRI and CT all have comparable high diagnostic accuracy in the initial diagnosis of CP. EUS and ERCP are outperformers and US has the lowest accuracy. The choice of imaging modality can therefore be made based on invasiveness, local availability, experience and costs. KEY POINTS • EUS, ERCP, MRI and CT have high diagnostic sensitivity for chronic pancreatitis • Diagnostic specificity is comparable for all imaging modalities • EUS and ERCP are outperformers and US has the lowest accuracy • The choice of imaging can be made based on clinical considerations.

Abstract
PURPOSE To determine if the T1 relaxation time of the pancreas can detect parenchymal changes in mild chronic pancreatitis (CP). MATERIALS AND METHODS This Institutional Review Board (IRB)-approved, Health Insurance Portability and Accountability Act (HIPAA)-compliant retrospective study analyzed 98 patients with suspected mild CP. Patients were grouped as normal (n = 53) or mild CP (n = 45) based on history, presenting symptomatology, and concordant findings on both the secretin-enhanced magnetic resonance cholangiopancreatography (S-MRCP) and endoscopic retrograde cholangiopancreatography (ERCP). T1 maps were obtained in all patients using the same 3D gradient echo technique on the same 3T scanner. T1 relaxation times, fat signal fraction (FSF), and anterior-posterior (AP) diameter were correlated with the clinical diagnosis of CP. RESULTS There was a significant difference (P < 0.0001) in the T1 relaxation times between the control (mean = 797 msec, 95% confidence interval [CI]: 730, 865) and mild CP group (mean = 1099 msec, 95% CI: 1032, 1166). A T1 relaxation time threshold value of 900 msec was 80% sensitive (95% CI: 65, 90) and 69% specific (95% CI: 56, 82) for the diagnosis of mild CP (area under the curve [AUC]: 0.81). Multiple regression analysis showed that T1 relaxation time was the only statistically significant variable correlating with the diagnosis of CP (P < 0.0001). T1 relaxation times showed a weak positive correlation with the pancreatic FSF (ρ = 0.33, P = 0.01) in the control group, but not in the mild CP group. CONCLUSION The T1 relaxation time of the pancreatic parenchyma was significantly increased in patients with mild CP. Therefore, T1 mapping might be used as a practical quantitative imaging technique for the evaluation of suspected mild CP. LEVEL OF EVIDENCE 3 J. Magn. Reson. Imaging 2017;45:1171-1176.

Risk of Recurrent Pancreatitis and Progression to Chronic Pancreatitis After a First Episode of Acute Pancreatitis. Clin Gastroenterol Hepatol 2016; 14:738-46. [PMID: 26772149 DOI: 10.1016/j.cgh.2015.12.040] [Citation(s) in RCA: 168] [Impact Index Per Article: 21.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/10/2015] [Accepted: 12/09/2015] [Indexed: 02/07/2023]
Abstract
BACKGROUND & AIMS Patients with a first episode of acute pancreatitis can develop recurrent or chronic pancreatitis (CP). However, little is known about the incidence or risk factors for these events. METHODS We performed a cross-sectional study of 669 patients with a first episode of acute pancreatitis admitted to 15 Dutch hospitals from December 2003 through March 2007. We collected information on disease course, outpatient visits, and hospital readmissions, as well as results from imaging, laboratory, and histology studies. Standardized follow-up questionnaires were sent to all available patients to collect information on hospitalizations and interventions for pancreatic disease, abdominal pain, steatorrhea, diabetes mellitus, medications, and alcohol and tobacco use. Patients were followed up for a median time period of 57 months. Primary end points were recurrent pancreatitis and CP. Risk factors were evaluated using regression analysis. The cumulative risk was assessed using Kaplan-Meier analysis. RESULTS Recurrent pancreatitis developed in 117 patients (17%), and CP occurred in 51 patients (7.6%). Recurrent pancreatitis developed in 12% of patients with biliary disease, 24% of patients with alcoholic etiology, and 25% of patients with disease of idiopathic or other etiologies; CP occurred in 3%, 16%, and 10% of these patients, respectively. Etiology, smoking, and necrotizing pancreatitis were independent risk factors for recurrent pancreatitis and CP. Acute Physiology and Chronic Health Evaluation II scores at admission also were associated independently with recurrent pancreatitis. The cumulative risk for recurrent pancreatitis over 5 years was highest among smokers at 40% (compared with 13% for nonsmokers). For alcohol abusers and current smokers, the cumulative risks for CP were similar-approximately 18%. In contrast, the cumulative risk of CP increased to 30% in patients who smoked and abused alcohol. CONCLUSIONS Based on a retrospective analysis of patients admitted to Dutch hospitals, a first episode of acute pancreatitis leads to recurrent pancreatitis in 17% of patients, and almost 8% of patients progress to CP within 5 years. Progression was associated independently with alcoholic etiology, smoking, and a history of pancreatic necrosis. Smoking is the predominant risk factor for recurrent disease, whereas the combination of alcohol abuse and smoking produces the highest cumulative risk for chronic pancreatitis.

Abstract
BACKGROUND Surgical excision by removal of the head of the pancreas to decompress the obstructed ducts is one of the treatment options for people with symptomatic chronic pancreatitis. Surgical excision of the head of the pancreas can be performed by excision of the duodenum along with the head of the pancreas (pancreaticoduodenectomy (PD)) or without excision of the duodenum (duodenum-preserving pancreatic head resection (DPPHR)). There is currently no consensus on the method of pancreatic head resection in people with chronic pancreatitis. OBJECTIVES To assess the benefits and harms of duodenum-preserving pancreatic head resection versus pancreaticoduodenectomy in people with chronic pancreatitis for whom pancreatic resection is considered the main treatment option. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, Science Citation Index Expanded, and trials registers to June 2015 to identify randomised trials. We also searched the references of included trials to identify further trials. SELECTION CRITERIA We considered only randomised controlled trials (RCT) performed in people with chronic pancreatitis undergoing pancreatic head resection, irrespective of language, blinding, or publication status, for inclusion in the review. DATA COLLECTION AND ANALYSIS Two review authors independently identified trials and extracted data. We calculated the risk ratio (RR), mean difference (MD), rate ratio (RaR), or hazard ratio (HR) with 95% confidence intervals (CI) based on an available-case analysis. MAIN RESULTS Five trials including 292 participants met the inclusion criteria for the review. After exclusion of 23 participants mainly due to pancreatic cancer or because participants did not receive the planned treatment, a total of 269 participants (with symptomatic chronic pancreatitis involving the head of pancreas and requiring surgery) were randomly assigned to receive DPPHR (135 participants) or PD (134 participants). The trials did not report the American Society of Anesthesiologists (ASA) status of the participants. All the trials were single-centre trials and included people with and without obstructive jaundice and people with and without duodenal stenosis but did not report data separately for those with and without jaundice or those with and without duodenal stenosis. The surgical procedures compared in the five trials included DPPHR (Beger or Frey procedures, or wide local excision of the head of the pancreas) and PD (pylorus-preserving pancreaticoduodenectomy or Whipple procedure). The participants were followed up for various periods of time ranging from one to 15 years. The trials were at unclear or high risk of bias. The overall quality of evidence was low or very low.The differences in short-term mortality (up to 90 days after surgery) (RR 2.89, 95% CI 0.31 to 26.87; 369 participants; 5 studies; DPPHR: 2/135 (1.5%) versus PD: 0/134 (0%); very low quality evidence) or long-term mortality (maximal follow-up) (HR 0.65, 95% CI 0.31 to 1.34; 229 participants; 4 studies; very low quality evidence), medium-term (three months to five years) (only a narrative summary was possible; 229 participants; 4 studies; very low quality evidence), or long-term quality of life (more than five years) (MD 8.45, 95% CI -0.27 to 17.18; 101 participants; 2 studies; low quality evidence), proportion of people with adverse events (RR 0.55, 95% CI 0.22 to 1.35; 226 participants; 4 studies; DPPHR: 23/113 (adjusted proportion 20%) versus PD: 41/113 (36.3%); very low quality evidence), number of people with adverse events (RaR 0.95, 95% CI 0.43 to 2.12; 43 participants; 1 study; DPPHR: 12/22 (54.3 events per 100 participants) versus PD: 12/21 (57.1 events per 100 participants); very low quality evidence), proportion of people employed (maximal follow-up) (RR 1.54, 95% CI 1.00 to 2.37; 189 participants; 4 studies; DPPHR: 65/98 (adjusted proportion 69.4%) versus PD: 41/91 (45.1%); low quality evidence), incidence proportion of diabetes mellitus (maximum follow-up) (RR 0.78, 95% CI 0.50 to 1.22; 269 participants; 5 studies; DPPHR: 25/135 (adjusted proportion 18.6%) versus PD: 32/134 (23.9%); very low quality evidence), and prevalence proportion of pancreatic exocrine insufficiency (maximum follow-up) (RR 0.83, 95% CI 0.68 to 1.02; 189 participants; 4 studies; DPPHR: 62/98 (adjusted proportion 62.0%) versus PD: 68/91 (74.7%); very low quality evidence) were imprecise. The length of hospital stay appeared to be lower with DPPHR compared to PD and ranged between a reduction of one day and five days in the trials (208 participants; 4 studies; low quality evidence). None of the trials reported short-term quality of life (four weeks to three months), clinically significant pancreatic fistulas, serious adverse events, time to return to normal activity, time to return to work, and pain scores using a visual analogue scale. AUTHORS' CONCLUSIONS Low quality evidence suggested that DPPHR may result in shorter hospital stay than PD. Based on low or very low quality evidence, there is currently no evidence of any difference in the mortality, adverse events, or quality of life between DPPHR and PD. However, the results were imprecise and further RCTs are required on this topic. Future RCTs comparing DPPHR with PD should report the severity as well as the incidence of postoperative complications and their impact on patient recovery. In such trials, participant and observer blinding should be performed and the analysis should be performed on an intention-to-treat basis to decrease the bias. In addition to the short-term benefits and harms such as mortality, surgery-related complications, quality of life, length of hospital stay, return to normal activity, and return to work, future trials should consider linkage of trial participants to health databases, social databases, and mortality registers to obtain the long-term benefits and harms of the different treatments.

Abstract
BACKGROUND Chronic abdominal pain is one of the major symptoms in people with chronic pancreatitis. The role of pregabalin in people with chronic pancreatic pain due to chronic pancreatitis is uncertain. OBJECTIVES To assess the benefits and harms of pregabalin in people with chronic abdominal pain due to chronic pancreatitis. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL) in The Cochrane Library 2015, issue 6, and MEDLINE, EMBASE, Science Citation Index Expanded, trials registers until June 2015. We also searched the references of included trials to identify further trials. SELECTION CRITERIA We considered only randomised controlled trials (RCT) performed in people with chronic pancreatic pain due to chronic pancreatitis, irrespective of language, blinding, or publication status for inclusion in the review. DATA COLLECTION AND ANALYSIS Two review authors independently identified trials and independently extracted data. We calculated the risk ratio (RR) or mean difference (MD) with 95% confidence intervals (CI) with RevMan 5, based on intention-to-treat analysis. MAIN RESULTS Only one study, funded by Pfizer, met the inclusion criteria for the review. A total of 64 participants (with chronic pain due to chronic pancreatitis) were randomly assigned to receive escalating doses of pregabalin (150 mg per day to 600 mg per day; 34 participants) or matching placebo (30 participants). Participants received pregabalin or placebo for three weeks on an outpatient basis; the outcomes were measured at the end of the treatment (i.e. three weeks from commencement of treatment). Potential participants taking concomitant analgesic medication and expected to stay on a stable regime during the trial were allowed to enter the study. This trial was at low risk of bias. The overall quality of evidence was low or moderate.Only the short-term outcomes were available in this trial. The medium and long-term outcomes, number of work days lost, and length of hospital stay due to admissions for pain control were not available. This trial found that the changes in opiate use (MD -26.00 mg; 95% CI -47.36 to -4.64; participants = 64; moderate-quality evidence), and pain score percentage changes from baseline (MD -12.00; 95% CI -21.82 to -2.18; participants = 64; moderate-quality evidence) were better in participants taking pregabalin compared to those taking placebo. This trial also found that there were more adverse events in participants taking pregabalin compared to those taking placebo (RR 1.71; 95% CI 1.20 to 2.43; participants = 64). The differences between pregabalin and placebo were imprecise for short-term health-related quality of life measured with the EORTC CLQ-30 questionnaire (MD 11.40; 95% CI -3.28 to 26.08; participants = 64; moderate-quality evidence), proportion of people with serious adverse events (RR 1.76; 95% CI 0.35 to 8.96; participants = 64; low-quality evidence), and proportion of people requiring hospital admissions (RR 0.44; 95% CI 0.04 to 4.62; participants = 64; low quality evidence). AUTHORS' CONCLUSIONS Based on low- to moderate-quality evidence, short-term use of pregabalin decreases short-term opiate use, and short-term pain scores, but increases the adverse events compared to placebo, in people with chronic pain due to chronic pancreatitis. The clinical implication of the decreases in short-term opiate use and short-term pain scores is not known.Future trials assessing the role of pregabalin in decreasing chronic pain in chronic pancreatitis should assess the medium- or long-term effects of pregabalin and should include outcomes such as, quality of life, treatment-related adverse events, number of work days lost, number of hospital admissions, and the length of hospital stay, in addition to pain scores, to assess the clinical and socioeconomic impact.

Abstract
Pancreatitis, or inflammation of the pancreas, is commonly seen in dogs and cats and presents a spectrum of disease severities from acute to chronic and mild to severe. It is usually sterile, but the causes and pathophysiology remain poorly understood. The acute end of the disease spectrum is associated with a high mortality but the potential for complete recovery of organ structure and function if the animal survives. At the other end of the spectrum, chronic pancreatitis in either species can cause refractory pain and reduce quality of life. It may also result in progressive exocrine and endocrine functional impairment. There is confusion in the veterinary literature about definitions of acute and chronic pancreatitis and there are very few studies on the pathophysiology of naturally occurring pancreatitis in dogs and cats. This article reviews histological and clinical definitions and current understanding of the pathophysiology and causes in small animals by comparison with the much more extensive literature in humans, and suggests many areas that need further study in dogs and cats.

Abstract
The immune system plays a complex role in the development and progression of pancreatic cancer. Inflammation can promote the formation of premalignant lesions and accelerate pancreatic cancer development. Conversely, pancreatic cancer is characterized by an immunosuppressive environment, which is thought to promote tumor progression and invasion. Here we review the current literature describing the role of the immune response in the progressive development of pancreatic cancer, with a focus on the mechanisms that drive recruitment and activation of immune cells at the tumor site, and our current understanding of the function of the immune cell types at the tumor. Recent clinical and preclinical data are reviewed, detailing the involvement of the immune response in pancreatitis and pancreatic cancer, including the role of specific cytokines and implications for disease outcome. Acute pancreatitis is characterized by a predominantly innate immune response, while chronic pancreatitis elicits an immune response that involves both innate and adaptive immune cells, and often results in profound systemic immune-suppression. Pancreatic adenocarcinoma is characterized by marked immune dysfunction driven by immunosuppressive cell types, tumor-promoting immune cells, and defective or absent inflammatory cells. Recent studies reveal that immune cells interact with cancer stem cells and tumor stromal cells, and these interactions have an impact on development and progression of pancreatic ductal adenocarcinoma (PDAC). Finally, current PDAC therapies are reviewed and the potential for harnessing the actions of the immune response to assist in targeting pancreatic cancer using immunotherapy is discussed.

Abstract
Chronic pancreatitis (CP) is a progressive inflammatory and fibrotic disease of the pancreas which encompasses a variety of clinical syndromes ranging from mild to life-threatening complications. Metabolomics has increasingly been applied to identify biomarkers for disease diagnosis with particular interest in diseases at an early stage. In this study, we tested a swine obstructive CP model by subtotal ligation of the main pancreatic duct, and the metabolic profiles of the Bama miniature swine pancreas were investigated using high-resolution magic angle spinning proton magnetic resonance spectroscopy (HR MAS (1)H MRS) combined with principal components analysis (PCA). Increases in lactate and choline for mild CP and decreases in glycerophosphocholine, phosphocholine, betaine and glycine were observed from normal pancreas to mild, moderate and severe CP. PCA results showed visual separations among the groups. The increase of choline at an early stage of CP and the decrease of glycerophosphocholine, phosphocholine, betaine and glycine reveal the pathogenesis of CP at a molecular level. The MRS results presented here demonstrate the potential of metabolic profiles in discriminating a normal pancreas from different stages of CP, which may be used to achieve CP early diagnosis and timely intervention to prevent irreversible destruction of the pancreas.

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
OBJECTIVES There is limited literature on acute pancreatitis (AP), acute recurrent pancreatitis (ARP), and chronic pancreatitis (CP) in children. The International Study Group of Pediatric Pancreatitis: In Search for a Cure (INSPPIRE) consortium was formed to standardize definitions, develop diagnostic algorithms, investigate disease pathophysiology, and design prospective multicenter studies in pediatric pancreatitis. METHODS Subcommittees were formed to delineate definitions of pancreatitis, and a survey was conducted to analyze present practice. RESULTS AP was defined as requiring 2 of the following: abdominal pain compatible with AP, serum amylase and/or lipase values ≥3 times upper limits of normal, and imaging findings of AP. ARP was defined as ≥2 distinct episodes of AP with intervening return to baseline. CP was diagnosed in the presence of typical abdominal pain plus characteristic imaging findings, or exocrine insufficiency plus imaging findings, or endocrine insufficiency plus imaging findings. We found that children with pancreatitis were primarily managed by pediatric gastroenterologists. Unless the etiology was known, initial investigations included serum liver enzymes, triglycerides, calcium, and abdominal ultrasound. Further investigations (usually for ARP and CP) included magnetic resonance or other imaging, sweat chloride, and genetic testing. Respondents' future goals for INSPPIRE included determining natural history of pancreatitis, developing algorithms to evaluate and manage pancreatitis, and validating diagnostic criteria. CONCLUSIONS INSPPIRE represents the first initiative to create a multicenter approach to systematically characterize pancreatitis in children. Future aims include creation of patient database and biologic sample repository.

Abstract
Chronic pancreatitis is a progressive fibroinflammatory disease that exists in large-duct (often with intraductal calculi) or small-duct form. In many patients this disease results from a complex mix of environmental (eg, alcohol, cigarettes, and occupational chemicals) and genetic factors (eg, mutation in a trypsin-controlling gene or the cystic fibrosis transmembrane conductance regulator); a few patients have hereditary or autoimmune disease. Pain in the form of recurrent attacks of pancreatitis (representing paralysis of apical exocytosis in acinar cells) or constant and disabling pain is usually the main symptom. Management of the pain is mainly empirical, involving potent analgesics, duct drainage by endoscopic or surgical means, and partial or total pancreatectomy. However, steroids rapidly reduce symptoms in patients with autoimmune pancreatitis, and micronutrient therapy to correct electrophilic stress is emerging as a promising treatment in the other patients. Steatorrhoea, diabetes, local complications, and psychosocial issues associated with the disease are additional therapeutic challenges.
