Obesity surgery

Obese patients undergoing bariatric surgery are at significant risk for venous thromboembolism (VTE). We performed a multicenter, retrospective survey to evaluate the safety and efficacy of enoxaparin for thromboprophylaxis in patients with morbid obesity undergoing primary bariatric surgery. ⋯ The administration of enoxaparin, in various dosing regimens, is safe for thromboprophylaxis in morbidly obese patients undergoing bariatric surgery. Fewer events occurred with perioperative prophylaxis initiated in the hospital. Because all thromboembolic events occurred after the cessation of thromboprophylaxis, extended thromboprophylaxis may be of value.
