This calculates the severity grades according to the ISGPS leak definition for pancreatic fistula and delayed gastric emptying (DGE).
This is a calculator of the new standardized definition for postoperative pancreatic “fistula” (POPF) or “leak”. It should be noted that clearly differentiating between Grade B and C fistula is difficult and for this reason, in most publications, Grade B/C are grouped together as one entity. This calculator is based on International Study Group of Pancreatic Surgery (ISGPS) definitions published by Bassi, et al., Surgery 2005; 138:8-13 and Wente, et al., Surgery 2007; 142:761-8.
We would like to acknowledge that in order to maintain uniformity, we have presented this calculator in a similar format to that of the USA Pancreas Club
