Lee HJ, et al. - Based on the 2016 Revised International Study Group of Pancreatic Fistula (ISGPF) classification, researchers defined and correlated multidetector CT (MDCT) findings of pancreatic fistula after pancreaticoduodenectomy with surgical grading. Two hundred thirty-five patients with periampullary tumor had pancreaticoduodenectomy and postoperative MDCT between May 2011 and December 2016. With regard to the presence of a pancreatic fistula, the results of postoperative multidetector CT correlate well with surgical grading based on the International Study Group of Pancreatic Fistula classification. Following pancreaticoduodenectomy, multidetector CT may provide reliable information to suggest pancreatic fistula.
