BACKGROUND: Although laparoscopic repair of ventral hernia has become increasingly popular, its outcomes relative to open repair have not been well characterized. For this reason, we performed a meta-analysis of studies comparing open and laparoscopic ventral (including incisional) hernia repair. HYPOTHESIS: Laparoscopic ventral hernia repair results in better short-term outcomes than open ventral hernia repair. DATA SOURCES: Structured MEDLINE search for published studies. One unpublished study was also identified. STUDY SELECTION: Studies were selected on the basis of study design (comparison of laparoscopic and open ventral hernia repair). The 3 main outcome measures were perioperative complications, operative time, and length of hospital stay. Of 83 potential studies identified by abstract review, 8 (10%) met the inclusion criteria. DATA EXTRACTION: Two reviewers assessed each article to determine eligibility for inclusion and, where appropriate, abstracted information on patient characteristics and main outcome measures. DATA SYNTHESIS: Across 8 studies, 390 patients underwent open repair and 322 underwent laparoscopic repair. Perioperative complications were less than half as likely to occur in patients undergoing laparoscopic repair (14% vs 27%; P =.03; odds ratio, 0.42; 95% confidence interval, 0.29-0.68). Average length of stay was shorter in the laparoscopic group (2.0 vs 4.0 days; P =.02). No statistically significant difference in operative times was noted between laparoscopic and open repair (99 vs 96 minutes; P =.38). CONCLUSIONS: Laparoscopic ventral hernia repair offers lower complication rates and shorter length of stay than open repair. However, randomized controlled trials and studies with long-term follow-up are needed to confirm these findings and to assess long-term rates of hernia recurrence.
