Extended-duration thromboprophylaxis following major abdominopelvic surgery - For everyone or selected cases only?

Major abdominopelvic surgery is an important risk factor for postoperative venous thromboembolism (VTE). VTE is the leading cause of 30-day postoperative mortality in patients with cancer undergoing major abdominopelvic surgery. Randomized controlled trials have shown that extended duration thromboprophylaxis using a low molecular weight heparin or a direct oral anticoagulant significantly decreases the risk of overall VTE (symptomatic events and asymptomatic deep vein thrombosis). Hence, several clinical practice guidelines suggest the use of extended duration thromboprophylaxis for all high-risk patients undergoing major abdominopelvic surgery. Despite these recommendations by clinical practice guidelines, adoption of extended duration thromboprophylaxis in clinical practice remains low and clinical equipoise seems to persist. In this narrative review, we aim is to highlight and summarize the reasons that may explain discrepancy between clinical guideline recommendations and current practice regarding extended duration thromboprophylaxis in this patient population. We also aim to review different personalized approaches based on patients' individualized risk of VTE that may foster shared decision making and improve patient outcomes by reducing decisional conflict, increasing patient knowledge, and increasing risk perception accuracy.
