Background: Surgical site infections (SSIs) remain prevalent after ventral hernia repair (VHR). In 2013-2014, a safety-net academic hospital initiated a two-pronged quality-improvement (QI) project: (1) Development and implementation of evidence-based guidelines; and (2) creation of a specialized hernia clinic to manage challenging patients and complex ventral hernias. Our objective was to decrease SSI rates after elective VHR., Methods: The primary outcome was SSI 30 days post-operatively, which was assessed in aggregate and with a stratified analysis based on case complexity using the χ 2 test., Results: A total of 399 patients in the pre-QI period and 390 patients in post-QI period (178 patients in general surgery clinics; 212 patients in the specialty hernia clinic) underwent VHR. Patients treated in the post-QI period were less likely to experience an SSI (13.5% vs. 1.5%; p < 0.001). On subgroup analysis of the post-QI clinics, specialty hernia clinic patients had an even lower risk of SSI than those in general surgery clinics (1.4% versus 1.7%)., Conclusions: The QI initiatives of evidence-based guidelines and the specialty hernia clinic were associated with lower SSI rates. Differences in peri-operative management included differences in patient selection and pre-operative preparation and increased use of synthetic mesh and laparoscopy. Future studies must investigate the long-term outcomes of these initiatives.

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.
