Profilaxis de la tromboembolia venosa en cirugía bariátrica: puesta al día de la literatura

Introduction: Rates of obesity have been increasing worldwide and with the current situation obesity now represents an epidemic. Bariatric surgery is one the most effective ways to help reduce weight and sustain weight loss. Venous thromboembolism is a major cause of morbidity and mortality among bariatric surgery patients with no clearly established guidelines on prophylaxis. Areas covered: In this review the authors summarize clinical studies evaluating unfractionated heparin (UFH) and low molecular weight heparins (LMWH) in bariatric surgery patients. The authors present studies that assessed venous thromboembolic (VTE)-related risk stratification but also various dosing regimens of heparin products in this population of patients. Moreover, the authors will also present the feasibility of using direct oral anticoagulants (DOACs) for venous thromboembolism (VTE) prevention along with providing a summary of few current guidelines for VTE prevention in bariatric surgery patients. Expert opinion: Based on the data presented in this review, the authors conclude that LMWHs may be better options than UFH for VTE prophylaxis in bariatric surgery patients. We also conclude that risk stratifying bariatric patients may be a better approach when deciding on the best thromboprophylaxis modality, dose and duration.

El resumen se deja sin traducir para conservar la redacción original de los autores.

Los autores resumen estudios clínicos con heparina no fraccionada (HNF) y heparinas de bajo peso molecular (HBPM) en cirugía bariátrica: estratificación de riesgo tromboembólico, pautas de dosificación, viabilidad de los anticoagulantes orales directos (ACOD) y guías actuales. No hay pautas profilácticas claramente establecidas pese a que la tromboembolia venosa es causa importante de morbilidad y mortalidad. En su opinión, las HBPM quizá sean mejores que la HNF y estratificar el riesgo puede orientar modalidad, dosis y duración.
