Review Historical Article
[The systematic review is the foundation of evidence based medicine. One of the most important contributions to clinical medicine of the past decade].
The traditional narrative review has been shown repeatedly to be biased, mostly towards exaggerated treatment size effects. In contrast, the systematic review follows a strict protocol regarding focused questions, explicit criteria for literature searches, inclusion and exclusion criteria, critical appraisal and a synthesis which is quantitative when appropriate. ⋯ In this paper three sources of systematic reviews are identified: the Cochrane Library, reviews published in peer-reviewed journals, and assessments of health technology (HTA-reports). Editors are encouraged to publish systematic reviews after proper critical appraisal, and readers are advised to search for such reviews when in need of guidance on important clinical questions.

During recent years new concepts and methods have been introduced in the management of acute pancreatitis. Severity and risk of complications show wide variation. Outcome is also dependent on the physician's experience and on his local resources. ⋯ Furthermore, guidelines are offered for treatment of mild and severe pancreatitis, as well as for the management of pseudocysts. The role of multidisciplinary intensive care specialist teams in the management of severe disease is emphasized. The guidelines are supported by the Swedish Society of Gastroenterology, the Swedish Society of Gastroenterology, the Swedish Society of Anesthesiology and Intensive Care and by experts from other Nordic countries.
