BackgroundWith the rising prevalence of obesity, its impact on the severity and outcome of acute pancreatitis remains an important consideration when managing obese patients with acute pancreatitis.ObjectiveTo determine the clinical relevance of obesity in acute pancreatitis.MethodsA series of clinically relevant questions were framed which formed the basis of our literature search using PubMed and EMBASE databases. These related to acute pancreatitis severity, systemic inflammatory response, mortality, local and systemic complications. The search was restricted to human studies. Studies were classified according to the Oxford Centre for Evidence Based Medicine levels of evidence 1 for prognostic studies. Obesity was defined according to the guidelines of the World Health Organization. In keeping with studies included the binary classification (mild and severe) of acute pancreatitis was used.ResultsObesity is associated with an amplified systemic inflammatory response in acute pancreatitis and is a prognostic factor for mortality, local, systemic complications and severity in acute pancreatitis. Obesity was not found to be an independent prognostic factor for mortality and organ failure in patients with acute pancreatitis. It was evident that further studies are required to determine whether incorporating obesity into existing scoring systems improves severity prediction. Emerging evidence suggests that an obesity paradox is present in patients with acute pancreatitis.ConclusionThis review demonstrates that obesity has a clinically relevant impact on the course and outcome of acute pancreatitis.Copyright © 2014 IAP and EPC.
