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.

Jeon CY, Whitcomb DC, Slivka A, Brand RE, Gelrud A, Tang G, Abberbock J, AlKaade S, Guda N, Mel Wilcox C, Sandhu BS, Yadav D. Lifetime Drinking History of Persons With Chronic Pancreatitis. Alcohol Alcohol 2020; 54:615-624. [PMID: 31603464 DOI: 10.1093/alcalc/agz072] [Citation(s) in RCA: 16] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/27/2019] [Revised: 07/30/2019] [Accepted: 08/01/2019] [Indexed: 12/14/2022] Open
Abstract
AIMS Cumulative consumption of alcohol and variations of alcohol intake by age are unknown in chronic pancreatitis (CP) patients in North America. This study summarizes the lifetime drinking history (LDH) by physician attribution of alcohol etiology, smoking status and sex in persons with CP. METHODS We analyzed data on 193 CP participants who completed the LDH questionnaire in the North American Pancreatitis Continuation and Validation Study (NAPS2-CV). We collected data on frequency of drinking and drinks per drinking day for each drinking phase of their lives. We examined differences in total number of alcoholic drinks and weight of ethanol consumed by physician's assessment of CP etiology, sex and smoking status. We also compared intensity of drinking in 20, 30 and 40s by timing of CP diagnosis. RESULTS Persons diagnosed with alcoholic CP consumed median of 34,488 drinks (interquartile range 18,240-75,024) prior to diagnosis of CP, which occurred earlier than in persons with CP of other etiology (47 vs. 52 years). Cumulative drinking was greater in male vs. female patients. Male CP patients with a diagnosis of CP before the age of 45 drank more intensely in their 20s as compared to those with later onset of disease. Current smoking was prevalent (67%) among those diagnosed with alcoholic CP. Twenty-eight percent of patients without physician attribution of alcohol etiology reported drinking heavily in the past. CONCLUSIONS Lifetime cumulative consumption of alcohol and prevalence of current smoking are high in persons diagnosed with alcoholic pancreatitis. Intense drinking in early years is associated with earlier manifestation of the disease.

Abstract
Knowledge of pancreatitis in the 20th century was shaped predominantly by animal data and clinical trials. Several large general population-based cohort studies and comprehensive systematic literature reviews in the 21st century have had a major effect on our understanding of pancreatitis and its sequelae. This Review provides precise and up-to-date data on the burden of acute pancreatitis, chronic pancreatitis and post-pancreatitis diabetes mellitus. Exocrine pancreatic insufficiency and altered bone metabolism following pancreatitis are also discussed. Furthermore, the article introduces a framework for the holistic prevention of pancreatitis with a view to providing guidance on strategies and intervention objectives at primary, secondary and tertiary levels. Concerted efforts by not only gastroenterologists and surgeons but also primary care physicians, endocrinologists, radiologists, pain specialists, dietitians, epidemiologists and public health specialists will be required to reduce meaningfully the burden of pancreatitis and its sequelae over the ensuing decades.

Abstract
AIM Acute pancreatitis is associated with significant morbidity and mortality. In the United States, more than 3,00,000 patients are admitted and about 20,000 die from acute pancreatitis per year. In Taiwan, the incidence rate of acute pancreatitis is 0.03% and the mortality rate among severe acute pancreatitis is 16.3%. The aim of the study was to evaluate the impact of the global budgeting system on health service utilization, health care expenditures, and quality of care among patients with acute pancreatitis in Taiwan. MATERIALS AND METHODS The National Health Insurance Research Database (NHIRD) was used for analysis. Data on patients with acute pancreatitis diagnosed during the period 2000 and 2001 were used as baseline data, and data from 2004 and 2005 were used as post-intervention data. The length of stay (LOS), diagnostic costs, drug cost, therapy costs, total costs, risk of readmission within 14 days, and risk of revisiting the emergency department (ED) within 3 days of discharge before and after implementation of the global budgeting system were compared and analyzed. RESULTS Data on 2810 patients with acute pancreatitis were analyzed in this study. There was a significant difference in mean LOS before and after introduction of the global budget system (7.34 ± 0.22 days and 7.82 ± 0.22 days, respectively; P < .001)). The mean total costs before and after implementation of the global budget system were Taiwan dollars (NT$) 28,290.66 ± 1576.32 and NT$ 42,341.83 ± 2285.23, respectively. The mean rate of revisiting the ED within 3 days decreased from 9.9 ± 0.9% before adoption of global budgeting to 7.2 ± 0.6% after implementation of the system. The mean 14-day re-admission rates before and after introduction of global budgeting were 11.6 ± 1.0% and 7.9 ± 0.7%, respectively. CONCLUSION The global budget system was associated with significantly longer length of stay, higher health care expenditures, and better quality of care in patients treated for acute pancreatitis.

Abstract
Acute pancreatitis can present as sudden, expected death and, therefore, fall under the jurisdiction of the medical examiner/coroner (ME/C). Although its etiologies are varied, alcohol abuse, trauma, and drugs are important to consider in the forensic setting. It is therefore important for the forensic pathologist to have an understanding of these and other etiologies, to have a functional knowledge of the pancreatic anatomy and physiology, and to be able to diagnose acute pancreatitis and distinguish it from postmortem artifact. This review will highlight the forensic aspects of acute pancreatitis, with particular focus on acute hemorrhagic pancreatitis. This will include an overview of the developmental anatomy and normal physiology of the pancreas, the various causes of pancreatitis that may result in deaths coming to the attention of the ME/C, the underlying pathophysiology of the disease, the postmortem diagnosis of acute pancreatitis, and ancillary studies that support the diagnosis.

Abstract
OBJECTIVE This study aimed to investigate the association between chronic pancreatitis and smoking or genetic mutations. METHODS The study sample comprised 148 patients with chronic pancreatitis, 110 chronic alcoholic subjects without pancreatic disease, and 297 volunteer blood donors. RESULTS Of the patients with chronic pancreatitis, 74% had alcoholic etiology and 26% had idiopathic pancreatitis. The frequency of smoking was 91.4% in patients with alcoholic pancreatitis, higher than 73.3% in alcoholic subjects without pancreatitis (P < 0.01). The difference in smoking frequency was not significant between the patients with idiopathic pancreatitis and blood donors. The N34S mutation of serine peptidase inhibitor, Kazal type 1 (SPINK1) was found in 2.7% of patients with chronic alcoholic pancreatitis, in 5.3% of patients with idiopathic pancreatitis, and in 0.4% of blood donors (P = 0.02). The P55S mutation of SPINK1 was found in 2.7% of patients with alcoholic pancreatitis and in 0.7% of blood donors (P = 0.12). The R254W mutation of chymotrypsin C was found in 0.9% of patients with alcoholic pancreatitis, in 0.9% of chronic alcoholic subjects without pancreatitis, and in 0.4% of blood donors (P = 0.75). In all cases, the mutations were heterozygous. CONCLUSIONS Smoking and the N34S mutation of SPINK1 were positively correlated with chronic pancreatitis.

Abstract
Among the numerous etiologies of acute and chronic pancreatitis, several underlying causes (e.g., chronic alcohol abuse, trauma, medical therapy) may result in a death that is reportable to the medical examiner/coroner. As such, forensic pathologists are likely to encounter pancreatitis at autopsy and therefore must be familiar with its etiologies, mechanisms of death, autopsy findings, and medicolegal investigation. This review will focus on the aspects of pancreatitis that may be useful to forensic pathologists in their daily practice. This includes determining if acute or chronic pancreatitis caused or contributed to death as well as determining the etiologically specific proximate cause of death. Current theories of how these various processes result in inflammation of the pancreas are reviewed.

Abstract
BACKGROUND It remains unknown whether nabumetone increases or decreases acute pancreatitis risk. To investigate this, we conducted a population-based case-control study using the database from the Taiwan National Health Insurance Program. METHODS We analysed 5384 cases aged 20-84 years who had their first attack of acute pancreatitis during 1998-2011 and 21,536 controls without acute pancreatitis, and matched them according to sex, age and year in which acute pancreatitis was diagnosed. Never use of nabumetone was defined as subjects who had never received a nabumetone prescription; active use as subjects receiving a minimum of one prescription for nabumetone within 7 days before acute pancreatitis diagnosis and non-active use of nabumetone as subjects who did not receive a prescription for nabumetone within 7 days before but received at least one prescription for nabumetone ≥8 days before. The odds ratio and 95% confidence interval (CI) were estimated to investigate the risk of acute pancreatitis associated with nabumetone use, using the multivariable unconditional logistic regression model. RESULTS The adjusted odds ratio of acute pancreatitis was 3.69 (95%CI 1.69, 8.05) for subjects with active use of nabumetone compared with those with never use. The odds ratios decreased to 1.0 (95%CI 0.88, 1.12) for subjects with non-active use. CONCLUSIONS Active use of nabumetone may increase the risk of acute pancreatitis.

Abstract
Acute pancreatitis is a necro-inflammatory disease of the exocrine pancreas that is characterized by inappropriate activation of zymogens, infiltration of the pancreas by inflammatory cells, and destruction of the pancreatic exocrine cells. Acute pancreatitis can progress to a severe life-threatening disease. Currently there is no pharmacotherapy to prevent or treat acute pancreatitis. One of the more common factors associated with acute pancreatitis is alcohol abuse. Although commonly associated with pancreatitis alcohol alone is unable to cause pancreatitis. Instead, it appears that alcohol and its metabolic by-products predispose the pancreas to damage from agents that normally do not cause pancreatitis, or to more severe disease from agents that normally cause mild pancreatic damage. Over the last 10 to 20 years, a tremendous amount of work has defined a number of alcohol-mediated biochemical changes in pancreatic cells. Among these changes are: Sustained levels of intracellular calcium, activation of the mitochondrial permeability transition pore, endoplasmic reticulum stress, impairment in autophagy, alteration in the activity of transcriptional activators, and colocalization of lysosomal and pancreatic digestive enzymes. Elucidation of these changes has led to a deeper understanding of the mechanisms by which ethanol predisposes acinar cells to damage. This greater understanding has revealed a number of promising targets for therapeutic intervention. It is hoped that further investigation of these targets will lead to the development of pharmacotherapy that is effective in treating and preventing the progression of acute pancreatitis.

Abstract
Gallstone disease is the most common cause of acute pancreatitis in the Western world. In most cases, gallstone pancreatitis is a mild and self-limiting disease, and patients may proceed without complications to cholecystectomy to prevent future recurrence. Severe disease occurs in about 20% of cases and is associated with significant mortality; meticulous management is critical. A thorough understanding of the disease process, diagnosis, severity stratification, and principles of management is essential to the appropriate care of patients presenting with this disease. This article reviews these topics with a focus on surgical management, including appropriate timing and choice of interventions.

Abstract
BACKGROUND AND AIMS Knowledge of the long-term prognosis of acute pancreatitis (AP) is limited. The aims were to investigate: (1) prognostic factors associated with long-term mortality in patients with AP; (2) whether or not the level of serum (S-)amylase at admission had an impact on the prognosis; (3) causes of death in these patients. METHODS During 1977-1982, patients who were admitted to the five main hospitals in Copenhagen with a diagnosis of AP or chronic pancreatitis (CP) were included in a prospective cohort, the Copenhagen Pancreatitis Study (CPS); in 2008, they were followed up by linkage to the Danish Registries. The analyzed subcohort consisted of 352 patients with probable AP (n = 54) or definite AP (n = 298). RESULTS Multivariate Cox regression analysis showed that significant factors associated with mortality were age, alcohol, and diabetes, whereas female gender, co-living and employment were associated with better survival. The S-amylase level had no impact on mortality. The most frequent causes of death were cardiovascular diseases, digestive diseases, and malignancies. CONCLUSIONS Age, alcohol and diabetes had a significant impact on survival whereas the S-amylase level did not.

Abstract
Animal and clinical studies have shown that alcohol and its metabolic products, endotoxin, viral infection, drinking pattern, smoking, obesity, genetic variability, and gene polymorphisms were very important in the pathogenesis of alcoholic acute pancreatitis (AAP). The morbidity of AAP has been increased in the past decade, and male gender is strongly associated with increased risk of AAP. The mortality of AAP is high, while the quality of life of survivors of severe AAP is low. In this paper, we review the pathogenesis and clinical characteristics of AAP.

Abstract
The fundamental problem underlying pancreatic cancer is altered genetics. Rare germ-line mutations lead to familial cancer syndromes that may include pancreatic cancer. But why do some people develop pancreatic cancer while others develop cancer in other organs, or not at all? We discuss the possibility that other common germ-line mutations diminish the ability of pancreatic cells to protect themselves from environmental or metabolic stressors, resulting in reactive molecules that lead to cell injury and DNA damage-with a series of lucky hits knocking out key tumor-suppressor genes and activating oncogenes in at least one cell with clonal growth potential. Inflammation likely accelerates this process, whether or not it is clinically evident. We also note the significant effects of smoking, alcohol, antioxidants, and diet on risk, and that together they confer a major portion of attributable risk that may be linked to the injury-inflammation-cancer pathway. Because we cannot change our genes, lifestyle choices are currently the best way to reduce pancreatic cancer risk until more effective preventative strategies are developed.

Abstract
Acute pancreatitis is a relatively common disease that affects about 300,000 patients per annum in America with a mortality of about 7%. About 75% of pancreatitis is caused by gallstones or alcohol. Other important causes include hypertriglyceridemia, medication toxicity, trauma from endoscopic retrograde cholangiopancreatography, hypercalcemia, abdominal trauma, various infections, autoimmune, ischemia, and hereditary causes. In about 15% of cases the cause remains unknown after thorough investigation. This article discusses the causes, diagnosis, imaging findings, therapy, and complications of acute pancreatitis.

Abstract
Long-term excessive alcohol consumption is the most common risk factor for the development of chronic pancreatitis. Management of patients with alcohol-associated chronic pancreatitis can be complicated by problems associated with dependency, psychosocial burden, and physical changes like malnutrition and hepatic insufficiency. The records of 372 consecutive patients who underwent lateral pancreaticojejunostomy (LPJ, n = 184), pancreatoduodenectomy (PD, n = 97), or distal pancreatectomy (DP, n = 91) for chronic pancreatitis were retrospectively analyzed. Long-term outcome was assessed by patient survey with a median follow up of 5.5 ± 0.2 years. Of 372 patients, 171 underwent surgery for alcohol-associated chronic pancreatitis. According to patient questioning, the prevalence of alcohol cessation before surgery in the 171 patients was 81 per cent. Operative morbidity in the 171 patients was 20 per cent, 50 per cent, and 26 per cent after LPJ, PD, and DP, respectively, with an overall perioperative mortality rate of 2 per cent. None of the patients developed delirium tremens using an alcohol withdrawal protocol. Continued alcohol abuse before surgery did not affect perioperative morbidity ( P > 0.05). Follow up was available for a total of 229 patients, of which 39 per cent with alcohol-associated chronic pancreatitis had died compared with 16 per cent in the nonalcohol group ( P < 0.001). Of the remaining 171 patients, 45 per cent with alcohol-associated chronic pancreatitis had good pain control compared with 49 per cent of the remainder ( P > 0.05). Continuation of alcohol abuse after operation did not affect success for pain control at follow up ( P > 0.05). Surgical treatment of alcohol-associated chronic pancreatitis can be performed with similar morbidity and mortality compared with other forms of chronic pancreatitis. Alcohol cessation is preferred but not mandated to achieve good operative long-term outcome. Caution needs to be taken to prevent postoperative alcohol withdrawal. Long-term follow up with psychosocial support and management of co-existing addictions is important.

Background The complex interactions between recurrent trypsin-mediated pancreatic injury, alcohol-associated pancreatic injury and SPINK1 polymorphisms in chronic pancreatitis (CP) are undefined. We hypothesize that CP occurs as a result of multiple pathological mechanisms (pathways) that are initiated by different metabolic or environmental factors (etiologies) and may be influenced differentially by downstream genetic risk factors. We tested this hypothesis by evaluating the differences in effect size of the high risk SPINK1 N34S haplotype on CP from multiple etiologies after combining clinical reports of SPINK1 N34S frequency using meta-analysis. Methods and Findings The Pubmed and the Embase databases were reviewed. We studied 24 reports of SPINK1 N34S in CP (2,421 cases, 4,857 controls) using reported etiological factors as surrogates for pathways and multiple meta-analyses to determine the differential effects of SPINK1 N34S between alcoholic and non-alcoholic etiologies. Using estimates of between-study heterogeneity, we sub-classified our 24 studies into four specific clusters. We found that SPINK1 N34S is strongly associated with CP overall (OR 11.00; 95% CI: 7.59–15.93), but the effect of SPINK1 N34S in alcoholic CP (OR 4.98, 95% CI: 3.16–7.85) was significantly smaller than in idiopathic CP (OR 14.97, 95% C.I. = 9.09–24.67) or tropical CP (OR 19.15, 95% C.I. = 8.83–41.56). Studies analyzing familial CP showed very high heterogeneity suggestive of a complex etiology with an I2 = 80.95%. Conclusion The small effect of SPINK1 N34S in alcoholic subjects suggests that CP is driven through a different pathway that is largely trypsin-independent. The results also suggest that large effect sizes of SPINK1 N34S in small candidate gene studies in CP may be related to a mixture of multiple etiologic pathways leading to the same clinical endpoint.
