Abstract

Background: We evaluated the association between operating room time and developing a deep vein thrombosis (DVT)or pulmonary embolus (PE)after emergency general surgery (EGS). Methods: We reviewed six common EGS procedures in the 2013–2015 NSQIP dataset. After tabulating their incidence of postoperative VTE events, we calculated predictors of developing a VTE using adjusted multivariate logistic regressions. Results: Of 108,954 EGS patients, 1,366 patients (1.3%)developed a VTE postoperatively. The median time to diagnosis was 9 days [5–16]for DVTs and 8 days [5–16]for PEs. Operating room time of 100 min or more was associated with increased risk of developing a DVT (OR 1.30 [1.12–2.21])and PE (OR:1.25 [1.11–2.43])with a 7% and 5% respective increase for every 10 min increase after the 100 min. Other independent predictors of VTE complications were older age, and history of cancer, and emergent colectomies on procedure-level analysis. Conclusion: Prolonged operating room time is independently associated with increased risk of developing VTE complications after an EGS procedure. Most of the VTE complications were delayed in presentation.
