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.

ETFI is a frequent problem in adult hospitalized patients receiving ETF, and it is associated with poor clinical outcomes such as inadequate nutrition and complications of feeding. While the pathophysiology is poorly understood, there also appears to be no standard evidence-based treatment. Studies investigating the mechanisms and optimized management are therefore indicated.

Presence of fat in the pancreas increases the risk of metabolic co-morbidities. Detection and quantification of pancreatic fat is not a routine clinical practice, at least in part because of need to use expensive imaging techniques. We aimed to systematically review common markers of pancreatic fat in blood and to investigate differences in these markers associated with fatty pancreas. The search was conducted in 3 databases (EMBASE, Scopus, and MEDLINE). Studies in humans were eligible for inclusion if they reported on biological markers and percentage of pancreatic fat or fatty pancreas prevalence. Data were pooled for correlation and effect size meta-analysis. A total of 17 studies including 11 967 individuals were eligible for meta-analysis. Markers of lipid metabolism, including circulating triglycerides (r = 0.38 [95% confidence interval (CI) 0.31, 0.46]) and high-density lipoprotein cholesterol (r = -0.33 [95% CI -0.35, -0.31]), and markers of glucose metabolism, including glycated haemoglobin (r = 0.39 [95% CI 0.30, 0.48], insulin (r = 0.38 [95% CI 0.33, 0.43]), and homeostasis model assessment-insulin resistance (r = 0.37 [95% CI 0.30, 0.44], yielded the best correlations with percentage of pancreatic fat. Further, effect size analysis showed large and medium effects for the above markers of lipid and glucose metabolism. Circulating levels of triglycerides and glycated haemoglobin appear to be the best currently available markers of pancreatic fat. The approach of non-invasive and accurate detection of pancreatic fat by blood analysis should be further explored in the future, by investigating other potential biological markers of pancreatic fat.
