Abstract

BACKGROUND: Morbidly obese patients are at increased risk of venous thromboembolism (VTE) following surgery. This study explores the impact of a perioperative complication on the risk of VTE after bariatric surgery.

METHODS: Patients who underwent bariatric surgery were identified from the American College of Surgeons National Surgical Quality Improvement Program dataset (2012-2014). The 17 most common perioperative complications were analyzed by multivariate regression analysis to determine the effect of complications on the risk of VTE.

RESULTS: The postoperative incidence of VTE was 0.5% (n = 59,424 bariatric surgeries). The average time to diagnosis of VTE was 11.6 days. 80% of VTE events occurred after discharge. A major complication occurred prior to VTE in 22.6% of patients. The more complications experienced by an individual patient, the more likely they were to experience VTE. Unadjusted thirty-day mortality increased 13.89-fold following VTE (p < 0.0001).

CONCLUSIONS: Postoperative complications significantly increase the risk of VTE following bariatric surgery.
