Inferior vena cava filters and postoperative outcomes in patients undergoing bariatric surgery: a meta-analysis
Open accessAbstract
Background: Pulmonary embolism(PE)accounts for almost 40% of perioperative deaths after bariatric surgery.Placement of prophylactic inferior vena cava(IVC) filter before bariatric surgery to improve outcomes has shown varied results. We performed a meta-analysis to evaluate post- operative outcomes associated with the preoperative placement of IVC filters in these patients. Methods: A systematic review was conducted by three investigators independently in PubMed, EMBASE, the Web of Science and Scopus until February 28,2013.Our search was restricted to studies in adult patients undergoing bariatric surgery with and without IVC filters. Primary outcomes were postoperative deep vein thrombosis(DVT),pulmonary embolism (PE),and postoperative mortality. Meta-analysis used random effects models to account for heterogeneity,and Sidik- Jonkman method to account for scarcity of outcomes and studies. Associations are shown as Relative Risks(RR) and 95% Confidence Intervals(CI). Results: Seven observational studies were identified (n=102,767), with weighted average inci- dences of DVT(0.9%),PE(1.6%),and mortality(1.0%)for a follow-up ranging from 3 weeks to 3 months. Use of IVC filters was associated with an approximately 3-fold higher risk of DVT and death that was nominally significant for the former outcome, but not the latter (RR2.81,95%CI 1.33-5.97, p=0.007; and RR 3.27,95%CI0.78-13.64, p=0.1, respectively);there was no difference in the risk of PE(RR1.02,95%CI0.31-3.77,p=0.9). Moderate to high heterogeneity of effects was noted across studies. Conclusions: Placement of IVC filter before bariatric surgery Is associated with higher risk of postoperative DVT and mortality. A similar risk of PE inpatients with and without IVC filter placement cannot exclude a benefit, given the potential large imbalance in risk at baseline.Ran- domized trials are needed before IVC placement can be recommended.

In a meta-analysis of six observational studies, inferior vena cava filters were associated with a similar risk of pulmonary embolism (RR 1.02, 95% CI 0.31 to 3.37) in patients undergoing bariatric surgery.
“Meta-analysis of six observational studies suggested higher risk of deep venous thrombosis (OR 2.81, 95% CI 1.33 to 5.97), similar risk of pulmonary embolism (RR 1.02, 95% CI 0.31 to 3.37) and a trend towards higher risk of mortality with inferior vena cava filters (RR 3.27, 95% CI 0.78 to 13.64), albeit with wide interval estimates (Supplementary Table S9) [64].”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
