Establishing a Quantitative Benchmark for Morbidity in Pancreatoduodenectomy Using ACS-NSQIP, the Accordion Severity Grading System, and the Postoperative Morbidity Index

The study aim was to quantify the burden of complications of pancreatoduodenectomy (PD).The Postoperative Morbidity Index (PMI) is a quantitative measure of the average burden of complications of a procedure. It is based on highly validated systems--ACS-NSQIP and the Modified Accordion Severity Grading System.Nine centers contributed ACS-NSQIP complication data for 1589 patients undergoing PD from 2005 to 2011. Each complication was assigned a...
