title: Laparoscopic repair reduces incidence of surgical site infections for all ventral hernias.
abstract: BACKGROUND
  The role of laparoscopic repair of ventral hernias remains incompletely defined. We hypothesize that laparoscopy, compared to open repair with mesh, decreases surgical site infection (SSI) for all ventral hernia types.
  
  
  METHODS
  MEDLINE, EMBASE, and Cochrane databases were reviewed to identify studies evaluating outcomes of laparoscopic versus open repair with mesh of ventral hernias and divided into groups (primary or incisional). Studies with high risk of bias were excluded. Primary outcomes of interest were recurrence and SSI. Fixed effects model was used unless significant heterogeneity, assessed with the Higgins I square (I(2)), was encountered.
  
  
  RESULTS
  There were 5 and 15 studies for primary and incisional cohorts. No difference was seen in recurrence between laparoscopic and open repair in the two hernia groups. SSI was more common with open repair in both hernia groups: primary (OR 4.17, 95%CI [2.03-8.55]) and incisional (OR 5.16, 95%CI [2.79-9.57]).
  
  
  CONCLUSIONS
  Laparoscopic repair, compared to open repair with mesh, decreases rates of SSI in all types of ventral hernias with no difference in recurrence. These data suggest that laparoscopic approach may be the treatment of choice for all types of ventral hernias.
