Why the study?
Although VTE prophylaxis in surgical patients is well established, the best way to prevent VTE in patients undergoing bariatric surgery is less clear.

Optimal VTE prophylaxis after bariatric surgery remains unclear; leaves open need for larger RCTs to guide practice.
Do pharmacological interventions prevent venous thromboembolism in people undergoing bariatric surgery?
Combined mechanical and pharmacological prophylaxis may reduce VTE events in bariatric surgery patients compared to mechanical prophylaxis alone, though evidence for other pharmacological comparisons remains of low certainty.
