Abstract

Background

Venous thromboembolism (VTE) is a significant source of postoperative morbidity and mortality in patients undergoing common oncologic procedures. We sought to estimate the effect of surgical approach on the risk of developing a VTE.

Methods

IBM Watson Health Marketscan Database was used to conduct this retrospective study. In total, 12 938 patients who underwent either a radical prostatectomy, partial colectomy, or hysterectomy via a minimally invasive or open approach. We used a propensity‐weighted logistic regression analysis to assess the independent effect of surgical approach on VTE. The primary outcome of interest was the 90‐day rate of VTE after surgery.

Results

Patients undergoing minimally invasive surgery across all three surgical procedures were noted to have a lower odds of developing a VTE: (radical prostatectomy, odds ratio [OR]: 0.667, 95% confidence interval [CI]: 0.500‐0.891; P = .006 |partial colectomy: OR, 0.620, 95% CI: 0.477‐0.805; P < .001| hysterectomy: OR, 0.549 95% CI: 0.353‐0.854; P = .008).

Conclusion

We found that a minimally invasive approach was associated with significantly lower odds of VTE compared with undergoing the same open procedure. This study highlights how surgical approach may be an independent risk factor for development of VTE and may elucidate potential risk mitigation strategy.
