Abstract
We read with great interest the excellent review article by O’Connor et al. [ [1] O’Connor K. Garcia Whitlock A.E. Tewksbury C. Williams N.N. Dumon K.R. Risk factors for postdischarge venous thromboembolism among bariatric surgery patients and the evolving approach to extended thromboprophylaxis with enoxaparin. Surg Obes Relat Dis. 2021; 17: 1218-1225 Google Scholar ] evaluating risk factors for venous thromboembolism (VTE) in postoperative bariatric surgery patients and discussing approaches to extended prophylaxis. This article reviewed 15 studies that assessed VTE risk factors in post–bariatric surgery patients and concluded that age, increasing weight, and male sex were the most pertinent risk factors. This article also examined the efficacy of VTE risk calculators related to bariatric patients. These risk calculators included in the article were the Caprini score developed in 2005, the pulmonary embolism risk score (PERS), the Michigan Bariatric Surgery Collaborative (MBSC) risk calculator, the Cleveland Clinic risk calculator, and the BariClot tool [ [1] O’Connor K.

Feimster, Slack, and Nimeri on our previously published review on extended thromboprophylaxis. As they accurately point out, the more recent risk calculators available (MBSC and BariClot and the updated Caprini score) view body mass index as a continuous variable. While these calculators have not been systematically validated against the same data set to determine which performs with the best sensitivity and specificity in identifying the best tool for practice, each has its benefits for potential use.
