The incidence of obesity has been increasing dramatically in the last 3 decades, affecting more than one third of the general population in Saudi Arabia [ 2 ]. Abbreviation: BMI, body mass index. The dose of LMWH is also higher than standard and could have contributed to bleeding outcomes. Indeed, the majority of studies of pharmacologic prophylaxis in this review evaluated adjusted-dose LMWH after bariatric surgery. There have been two published systematic reviews with meta-analyses addressing the use of VCF in bariatric surgery.

Early mobilization is essential for this population; therefore, the patients in our study were mobilized on post-operative day 1. Dosing of pharmacologic prophylaxis is challenging in postsurgical bariatric surgery patients because dosing by vte prophylaxis obesity surgery weight may lead to excessive anticoagulation and bleeding. Patients in the higher dose group had shorter operative times and length of hospital stay; other reported VTE risk factors were not different between groups. Adding chemoprophylaxis to sequential compression might not reduce risk of venous thromboembolism in bariatric surgery patients. William S. VTE is a challenging problem after bariatric surgery but there are few randomized controlled trials studying thromboprophylaxis in this population. Many proposed regimens of thromboprophylaxis have been used postoperatively in bariatric surgery patients, however, the optimal dose and duration is uncertain.

Conclusion Extended thromboprophylaxis after bariatric surgery appears to be an effective and safe strategy for VTE prevention. A standardized protocol vte prophylaxis obesity surgery 10—14 days of extended thromboprophylaxis was implemented at our institution. Evaluation of strategies to prevent VTE in bariatric surgery patients In this section, the literature evaluating different methods of VTE prevention in bariatric surgery patients is reviewed, including mechanical and pharmacologic approaches. In these evaluations, the effectiveness of prophylaxis and its safety are both considered since anticoagulants are protective against VTE but have the potential to increase postoperative bleeding.

Vte prophylaxis obesity surgery presence of multiple patient and procedural characteristics favoring higher risk of VTE were seen with greater frequency in the VCF group, and they were more likely to receive anticoagulation and SCD. Given the limited data, oral anticoagulants, including warfarin, are not recommended for VTE prophylaxis in bariatric surgery patients. However, the optimal approach remains unclear.

The rationale for the use of DOACs in patients who are obese comes from pharmacokinetic studies that included a small number of obese participants, showing that body weight or BMI had either modest or no effects on DOAC concentration and anti-Xa levels. Friday, July 23, Case 4: Anticoagulation as VTE prophylaxis in morbidly obese patients A year-old man presents for a total hip replacement for chronic osteoarthritis of the right knee. Obesity is a risk factor for osteoarthritis and the need of joint replacement.

In the meta-analysis by Kaw et al, prophylaxks the only vte prophylaxis obesity surgery measure of heterogeneity is I 2. Other centers used 40 mg enoxaparin doses with either once or twice daily dosing frequency. Each guideline is scheduled for periodic review to allow incorporation of pertinent new developments in medical research knowledge, and practice.

In this study, there was no benefit for prophylactic insertion of IVC filters. Comparative effectiveness of unfractionated and low-molecular-weight heparin for prevention of venous thromboembolism following bariatric surgery. Details regarding the patients who developed VTE are shown in Table 2. Blood Res.

Case vte prophylaxis obesity surgery Anticoagulation for acute VTE in a patient who is morbidly surgwry. Case 4 Commentary: This patient can be given the standard prophylactic dose of either dabigatran, rivaroxaban, or apixaban for 10 to 14 days after his knee replacement. A Doppler ultra-sound showed an acute deep vein thrombosis DVT involving the right common femoral, femoral, popliteal, and posterior tibial veins. Abstract Background: Morbidly obese patients are at high risk for developing venous thromboembolism VTE.

Table 2 Inclusion and exclusion criteria for identified publications. Am J Surg. The patients received 0. Am J Med. Morbidly obese patients are at high risk for developing venous thromboembolism VTE.

Fatal PE is a frequent cause of postoperative mortality in the bariatric surgery population [ 89 ]. Postoperative dose adjusted by antifactor-Xa level. Four bleedings occurred requiring transfusions. The optimal duration of thromboprophylaxis was studied in a randomized trial of patients undergoing laparoscopic colectomy for cancer. All events occurred after hospital discharge. The authors concluded that prolonged use of chemoprophylaxis is safe and reduces the risk of VTE compared to using 1 week of heparin 8.

Recent Articles. May Volume 7 Issue 6. Friday, July 16, No thrombotic events were observed postoperatively or at the 1- 3- and 6-month follow-up visits.

In the bariatric surgery literature, studies have indicated an increased risk of Ptophylaxis with open compared with laparoscopic procedures. Enoxaparin 1 mg per BMI unit rounded to nearest 5 mg preoperativethen enoxaparin 1 mg per BMI unit rounded to nearest 10 mg q12h postoperative. Each guideline is scheduled for periodic review to allow incorporation of pertinent new developments in medical research knowledge, and practice. Procedure-related risks factors for VTE Procedure-related factors for VTE after bariatric surgery include operative time, procedure type, postoperative complications, and whether the procedure is open or laparoscopic. Enoxaparin thromboprophylaxis in gastric bypass patients: extended duration, dose stratification, and antifactor Xa activity.

Morbid obesity Background: Evidence-based data on optimal approach for prophylaxis of deep venous thrombosis VTE and pulmonary embolism PE in bariatric operations is discussed. Init prophylqxis estimated that, globally, more than 1. Furthermore, adipose tissue secretes hormones such as leptin, resistin, and various cytokines that upregulate the expression of tissue factor, resulting in a prothrombotic state. Background: Morbidly obese patients are at high risk for developing venous thromboembolism VTE. Methods: Sincethe current situation for bariatric surgery has been examined by quality assurance study in Germany. Abstract Background: Morbidly obese patients are at high risk for developing venous thromboembolism VTE.

Data have not yet been published regarding outcomes using this prophlyaxis and any corresponding varied approaches. Pharacologic prophylaxis against venous thromboembolic coplciations is not mandatory for all laparoscopic Roux-en-Y gastric bypass procedures. Arch Intern Med. The primary outcome of the study was the incidence of symptomatic VTE, including PE, DVT, and splanchnic vein thrombosis within 3 months of bariatric surgery in patients who received thromboprophylaxis. In some cohort studies, different treatment groups were recruited consecutively over several years. Allman-Farinelli MA.

As a prospective multicenter observational study, data on the type, regimen, and prophylzxis course of VTE prophylaxis were documented. ASH Clinical News. Search in posts. Case 1 Commentary: After reviewing the risks and benefits of anticoagulant options, including evidence for the use of DOACs in patients who are morbidly obese, the patient preferred a DOAC over warfarin. None of these patients required a re-laparotomy for hemorrhage control. Current Issue.
