Smeets XJNM, et al. - In this investigation, researchers studied the relationship between obesity and mortality in acute pancreatitis (AP), as well as examined the link between obesity and necrosis, organ failure, multiple organ failure, and invasive intervention. Four electronic databases for prospective studies on obesity and outcomes in AP were systematically searched. The results of this individual patient data meta-analysis indicated that the development of organ failure and multiple organ failure in AP is independently associated with obesity. However, obesity and mortality, necrosis and intervention are not linked.
