Comparison of risk adjusted excess post-operative pancreatic fistula rates after pancreaticoduodenectomy using cumulative sum analysis.

Background: Post-operative pancreatic fistula (POPF) is a key outcome post pancreaticoduodenectomy. There are numerous POPF risk calculators but no agreed benchmark, a key component of meaningful audit. We compared observed versus predicted POPF for six risk adjusted POPF calculators, to ascertain how they differ and thus contribute to discussion around benchmarking.
