Comparison of figure of eight and traditional simple wire closure method to prevent dehiscence after sternal closure

Objective: To investigate significant differences, if any, between figure of-eight method and simple wire closure technique in reducing the incidence of infectious and non-infectious sternal dehiscence in patients undergoing sternal closure.Methods: The systematic review was conducted in the Cardiothoracic Surgery Department at Aga Khan University from 1st December 2015 to 13th December 2017. The review was registered with PROSPERO, the International Prospective Register of Systematic Reviews. Pubmed, Cochrane Library (Wiley) and Scopus databases were searched for articles published up to December 13, 2017. The search was limited to randomised control trials, clinical trials, retrospective cohort studies, journal analyses, systematic reviews and meta analyses. Cadaveric or animal studies and articles published in languages other than English were excluded.Results: Of the 286 articles retrieved, 265(92.6%) were excluded on the basis of study title and abstract. Another 15(5.2%) were excluded for being irrelevant to the topic n hand, and 6(2.1%) formed the final sample. Of them, 4(66.6%) studies showed no significant difference between the two techniques, while 2(33.3%) found figure-of-eight technique to be superior of the two.Conclusions: There was no significant difference between the figure-of eight method and the simple wire technique in reducing the risk of dehiscence in patients undergoing sternal closure
