Korpela T, et al. - This study was conducted to determine if the statin use has a protective impact against post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (PEP) and to assess the impact of other drugs on the incidence of PEP. In addition, researchers explored the link between the statin use and the severity of PEP as well as evaluated the effect of other risk and protective factors on the incidence of PEP. STARK is an international multicenter prospective cohort study. STARK study will determine whether statins, a safe, widely used and inexpensive drug, can modify the incidence of PEP. Centers from Spain, Italy, Croatia, Finland and Sweden joined this investigation.
