Abstract

BACKGROUND: Current data suggests that decreasing VTE incidence may require focus on other factors. This study aimed to identify perioperative risk factors for VTE in patients undergoing surgery for gastrointestinal (GI) malignancy.

METHODS: Patients undergoing surgery for GI malignancy from 2013 to 2016 were grouped according to whether or not they developed a postoperative VTE, and groups were compared along demographic, perioperative, and outcome variables.

RESULTS: Patients who developed VTE were more likely to be older (67 ± 11 VTE vs. 61 ± 10 no VTE, p = 0.04), male (92% vs. 59%, p = 0.02), and have a history of atrial fibrillation (39% vs. 11%, p = 0.01). They also experienced higher intraoperative blood loss (328 ± 724 mL no VTE vs. 918 ± 1885 mL VTE, p = 0.01). On multivariable analysis, history of atrial fibrillation was independently associated with development of postoperative VTE (odds ratio = 3.83, 95% confidence interval = 1.13-13.05, p = 0.03).

CONCLUSION: A prior history of atrial fibrillation independently predicts increased risk of developing VTE after surgery for GI malignancy. Improving understanding of the underlying VTE pathophysiology in these patients can help guide effective prevention strategies.
