Abstract    Objective    To analyze the clinical effectiveness of percutaneous US- or CT- guided catheter drainage (PCD) for severe acute pancreatitis complicated with infective pancreatic necrosis and the possible influencing factors. Methods    The clinical data of 34 cases of infective pancreatic necrosis treated by PCD from January 2008 to February 2010 in Jinling Hospital, Medicine School of Nanjing University were analyzed retrospective. All of them received PCD as the first choice for treatment. After that, they were divided into two groups according to different clinical effectiveness of PCD. The two groups were compared for demographics, systemic and local complications and clinical outcomes. Results    Ninteen of the 34 cases were cured through PCD alone (55.9%). Additionally, the number of catheter used for drainage and bacterial culture result were also similar between the two groups. Only the CT value and distribution range of infective pancreatic necrosis were different between them. The logistic regression analysis revealed similar results too. Conclusion    The CT value and distribution range of infective pancreatic necrosis could influence the success rate of PCD significantly and should be serious considered before the treatment decision.
