Review
Acute pancreatitis is a common indication for hospital admission, increasing in incidence, including in children, pregnancy and the elderly. Moderately severe acute pancreatitis with fluid and/or necrotic collections causes substantial morbidity, and severe disease with persistent organ failure causes significant mortality. The diagnosis requires two of upper abdominal pain, amylase/lipase ≥ 3 ×upper limit of normal, and/or cross-sectional imaging findings. Gallstones and ethanol predominate while hypertriglyceridaemia and drugs are notable among many causes. Serum triglycerides, full blood count, renal and liver function tests, glucose, calcium, transabdominal ultrasound, and chest imaging are indicated, with abdominal cross-sectional imaging if there is diagnostic uncertainty. Subsequent imaging is undertaken to detect complications, for example, if C-reactive protein exceeds 150 mg/L, or rarer aetiologies. Pancreatic intracellular calcium overload, mitochondrial impairment, and inflammatory responses are critical in pathogenesis, targeted in current treatment trials, which are crucially important as there is no internationally licenced drug to treat acute pancreatitis and prevent complications. Initial priorities are intravenous fluid resuscitation, analgesia, and enteral nutrition, and when necessary, critical care and organ support, parenteral nutrition, antibiotics, pancreatic exocrine and endocrine replacement therapy; all may have adverse effects. Patients with local complications should be referred to specialist tertiary centres to guide further management, which may include drainage and/or necrosectomy. The impact of acute pancreatitis can be devastating, so prevention or reduction of the risk of recurrence and progression to chronic pancreatitis with an increased risk of pancreas cancer requires proactive management that should be long term for some patients.

Review
There has been an increase in the incidence of acute pancreatitis reported worldwide. Despite improvements in access to care, imaging and interventional techniques, acute pancreatitis continues to be associated with significant morbidity and mortality. Despite the availability of clinical practice guidelines for the management of acute pancreatitis, recent studies auditing the clinical management of the condition have shown important areas of noncompliance with evidence-based recommendations. This underscores the importance of creating understandable and implementable recommendations for the diagnosis and management of acute pancreatitis. The purpose of the present guideline is to provide evidence-based recommendations for the management of both mild and severe acute pancreatitis as well as the management of complications of acute pancreatitis and of gall stone-induced pancreatitis.

Review
Acute pancreatitis is an inflammatory disease of the pancreas. The etiology and pathogenesis of acute pancreatitis have been intensively investigated for centuries worldwide. Many causes of acute pancreatitis have been discovered, but the pathogenetic theories are controversial. The most common cause of acute pancreatitis is gallstone impacting the distal common bile-pancreatic duct. The majority of investigators accept that the main factors for acute billiary pancreatitis are pancreatic hyperstimulation and bile-pancreatic duct obstruction which increase pancreatic duct pressure and active trypsin reflux. Acute pancreatitis occurs when intracellular protective mechanisms to prevent trypsinogen activation or reduce trypsin activity are overwhelmed. However, little is known about the other acute pancreatitis. We hypothesize that acute biliary pancreatitis and other causes of acute pancreatitis possess a common pathogenesis. Pancreatic hyperstimulation and pancreatic duct obstruction increase pancreatic duct pressure, active trypsin reflux, and subsequent unregulated activation of trypsin within pancreatic acinar cells. Enzyme activation within the pancreas leads to auto-digestion of the gland and local inflammation. Once the hypothesis is confirmed, traditional therapeutic strategies against acute pancreatitis may be improved. Decompression of pancreatic duct pressure should be advocated in the treatment of acute pancreatitits which may greatly improve its outcome.

Review
Diabetes following acute pancreatitis (AP) is becoming increasingly recognized. It is unclear what subtype of diabetes mellitus (DM) occurs; however, type 3c diabetes mellitus (T3cDM) is gaining increasing recognition. T3cDM has differing pathophysiology than other subtypes of DM and therefore differing disease course and treatment. Current studies have examined the incidence and prevalence of DM following AP, and meta-analyses have shown around 15% develop DM at 1 year with an increasing proportion developing DM at 5 years. It has been observed that some patients have transient hyperglycemia following AP episode with a subset developing persistent impaired glucose metabolism; however, the exact timeline is not well defined. The data on risk factors for developing DM after AP is limited and mixed; however, it is likely that severity of AP may impact the propensity to develop DM. Screening guidelines have not been established following AP; however, screening 1-year post-event will likely capture a sizable proportion of newly developed DM. The endocrine and exocrine pancreas are closely linked, and studies have found significant overlap in dysfunction of both after AP. Finally, there are some data to suggest that diabetes predisposes patients to structural changes in the pancreas and increased risk of developing AP.

Review
BACKGROUND
Severe acute pancreatitis (AP) continues to be a serious gastrointestinal disease with relevant morbidity and mortality.
SUMMARY
Successful clinical management requires close interdisciplinary cooperation and coordination from experienced gastroenterologists, intensive care physicians, surgeons, and radiologists. While the early phase of the disease is characterized by intensive care aspects that focus primarily on treatment of organ failure, later complications are characterized especially by (infected) necrotic collections. Here, we discuss current clinical standards and developments for conservative and interventional management of patients with severe AP. Key messages: Early targeted fluid therapy within the first 48 h is critical to improve the outcome of severe AP. Thoracic epidural analgesia may have prognostically beneficial effects due to suspected anti-inflammatory effects and increased perfusion of splanchnic vessels. Enteral feeding should be started early during severe AP. Persistent organ failure (>48 h) is the strongest predictor of poor prognosis, and local complications such as infected walled-off necrosis should be primarily treated by minimally invasive endoscopic step-up approaches that are usually superior to surgical therapy options.

Review
Acute pancreatitis may be associated with both local and systemic complications. Systemic injury manifests in the form of organ failure, which is seen in approximately 20% of all cases of acute pancreatitis and defines "severe acute pancreatitis." Organ failure typically develops early in the course of acute pancreatitis, but also may develop later due to infected pancreatic necrosis-induced sepsis. Organ failure is the most important determinant of outcome in acute pancreatitis. We review here the current understanding of the risk factors, pathophysiology, timing, impact on outcome, and therapy of organ failure in acute pancreatitis. As we discuss the pathophysiology of severe systemic injury, the distinctions between markers and mediators of severity are highlighted based on evidence supporting their causality in organ failure. Emphasis is placed on clinically relevant end points of organ failure and the mechanisms underlying the pathophysiological perturbations, which offer insight into potential therapeutic targets to treat.

Review
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.

Review
In the last 20 years, the diagnosis of pancreatitis has become more frequent as a result of improved diagnostic modalities such as abdominal ultrasound examination, advanced imaging, and immunoassays for the measurement of pancreatic lipase. Our aim is to provide a state-of-the-art overview of the clinical diagnosis of acute pancreatitis (AP) in dogs with a particular focus on pancreatic lipase assay validation and clinical performance, in addition to advanced imaging modalities. We also discuss the potential indications for cytology and histopathology in dogs with suspected AP.

Review
Hypertriglyceridemia is an uncommon but a well-established etiology of acute pancreatitis leading to significant morbidity and mortality. The risk and severity of acute pancreatitis increase with increasing levels of serum triglycerides. It is crucial to identify hypertriglyceridemia as the cause of pancreatitis and initiate appropriate treatment plan. Initial supportive treatment is similar to management of other causes of acute pancreatitis with additional specific therapies tailored to lower serum triglycerides levels. This includes plasmapheresis, insulin, heparin infusion, and hemofiltration. After the acute episode, diet and lifestyle modifications along with hypolipidemic drugs should be initiated to prevent further episodes. Currently, there is paucity of studies directly comparing different modalities. This article provides a comprehensive review of management of hypertriglyceridemia induced acute pancreatitis. We conclude by summarizing our treatment approach to manage hypertriglyceridemia induced acute pancreatitis.
